201005203 九、發明說明: 【發明所屬之技術領域】 本發明係關於一種檯燈,尤其是一種以發光二極體(light emitting diode,LED)作為光源的檯燈。 【先前技術】 發光二極體係一種可將電能轉換為光能之高效率冷光發 光元件’也是一種微小之固態光源(solidstateiUuminat〇r)。 發光一極體之主要構成部分係一半導體p_n接面結構。在此 P-n接面之兩端施加電壓以通入電流後,隨即產生電子與電 洞,電子與電洞往此p-n接面流動並結合而釋放出光子。 第1圖係一典型利用發光二極體元件作為光源之楼燈的 示意圖。如圖中所示,此檯燈10具有一底座12、一發光裝 置14與一支撐結構16。其令,支撐結構16係用以將發光裝 置14支撐於底座12上方一定高度處。發光裝置14具有一發 光面14a,以提供照明。 發光裝置14具有作為光源的複數個發光二極體元件 14b。這些發光二極體元件14b是直接設置於發光面Ma上’ 以&供照明。值得注意的I,由於發光二極體元件⑽是直 接設置於發光面14a上,發光裝置14的厚度至少必於發 光二極趙元件14b加上為了改善發光面14a之發光亮度與均 句度所需設置之光學結構(例如透鏡結構)的厚度。因此, 此種發光裝置14通常難以符合薄形化的要求。 其次’由於此發光裝置14是將多健現點絲發光之發 光二極趙元件14b設置於同-個平面上,來產生面光源的發 5 201005203 光效果,因此,難以避免光強度不均勻的間題,甚至可能會 — 在發光面14a的照明中出現各個發光二極體元件14b的影 • 像。此外,利用多個發光二極體元件14b來產生面光源的發 光效果,還可能導致多重影像的產生,甚至會有部分光線直 接投射至使用者的眼睛而令使用者感到不適。 【發明内容】 本發明之一實施例在於提供一種發光二極體檯燈,可達 到薄型化發光裝置的目的,同時也可以避免產生發光強度不 0 均勻的缺點。 本發明之一實施例在於提供一種具有夜燈功能之發光二 極體楼燈。 本發明之一實施例在於提供一種發光二極體檯燈,可依 據使用者之需求調整其照明的色溫。 本發明的其他目的和優點可以從本發明所揭露的技術特 徵中得到進一步的了解。 • 為達上述之一或部份或全部目的或是其他目的,本發明 之實施例提供一種發光二極體檯燈。此發光二極體檯燈包括 一底座、一發光裝置、一支撐結構與一觸發裴置。其中,發 光裝置具有一發光面。支撐結構之底端係轴接至底座,其頂 端係軸接至發光裝置。並且,支撐結構具有一對應於發光裝 置之本體,且本體具有至少一開孔,對應於發光裝置之發光 面°觸發裝置係設置於支撐結構與發光裝置間。當發光裝置 蓋合於支撐結構之本體時,發光面所產生之光線係經由開孔 向支撐結構之背面投射’同時’觸發裝置被觸發而調降發光 6 201005203 面之發光亮度。 在本發明之一實施例中,發光裝置具有一殼體、一導光 板、至少一光學膜片與至少一發光二極體。導光板係設置於 殼體内,且導光板具有一入光面及一與入光面連接之出光 面。光學膜片設置於導光板之出光面的上方。發光二極體係 鄰近於導光板之入光面。發光二極體所發出之光線經由入光 面入射至導光板’並由出光面出射至光學膜片,經由發光面 形成一面光源。 在本發明之一實施例中’發光裝置内装設有二種不同色 溫的發光二極體元件。並且’發光二極體檯燈具有一驅動電 路。此驅動電路具有一功率級與一控制級。功率級係提供電 流以驅動發光裝置内之發光二極體元件。控制級具有一第一 定電流控制器、一第二定電流控制器與一色溫亮度控制單 元。此色溫亮度控制單元可依據輸入之控制信號,透過第一 定電流控制器與第二定電流控制器,分別控制流經前揭二種 不同色溫之發光二極體元件之電流值。 在本發明之一實施例中’發光二極體檯燈具有一彩色透 光膜係裝設於支撐結構之本體内,並且覆蓋開孔。此彩色透 光膜可以改變經由開孔向外投射之光線的顏色。 傳統之發光二極體檯燈直接將複數個發光二極體元件設 置於發光面上以提供照明,會導致發光裝置難以薄形化,並 且會導致發光強度不均勻的問題。相較之下,本發明之實施 例之發光二極體所產生之光線係在導光板内被均勻混合後, 經由光學膜片,才向外投射,因而可以避免光強度不均勻的 7 201005203 問題,並且有助於達到薄型化的目的。其次,傳統的發光二 極趙檯燈通常僅能調整發光亮度而無法調整照明色溫。相較 ' 之下,本發明之-實施例之發光二極體檯燈具有一色溫亮度 ,制單元’可依據控偷號,透過第―定電流控制器與第二 定電流控_調整魅二種獨色溫之發光二極體元件之電 流大小與比例,以改變發光面的照明色溫。此外,當本發明 之實施例之發光二極雜叙發光裝置蓋合於支撐結構之本 趙時’觸發裝置會被觸發_降發絲之發絲度。同時, • 發光面所產生之光線會經過彩色透光膜朝向支樓結構背面的 方向投射,而呈現彩色的照明,有利於夜晚照明所需。 關於本發明之優點與精神可以藉由以下的發明詳述及所 附圖式得到進一步的瞭解。 【實施方式】 有關本發明之前述及其他技術内容、特點與功效,在以 下配合參考圖式之一較佳實施例的詳細說明中,將可清楚的 呈現。以下實施例中所提到的方向用語,例如··上、下、左、 • 右、前或後等’僅是參考附加圖式的方向。因此,使用的方 向用語是用來說明並非用來限制本發明。 第2Α與2Β圖係本發明發光二極體檯燈1〇〇

置140蓋合於支撐結構16〇之本體161時,觸發裝置即會受 到壓迫而調降發光面14〇a之發光亮度。其次,為了在發光裝 置140蓋合於支樓結構160之本體161後能夠固定發光裝置 140的位置,就一實施例而言,發光裝置14〇朝向支撐結構 160的表面可設置一卡勾,以卡合於支撐結構16〇。 值得注意的是,由於發光裝置140之發光面14〇a所提供 的通常是白色或是太陽色的_,未必符合夜燈所需的照明 色彩。因此’如第2B圖所示’本實施例之發光二極體楼燈 1〇〇具有一彩色透光膜180。支撐結構160之本體161的内部 具有-空間’以容納彩色透光膜18〇。當彩色透光膜⑽設 置於支撐結構160之本體161内的空間時,彩色透光膜 會覆蓋開孔162。當發光裝置140蓋合於支撐結構16〇之本 9 201005203 161時,發光面14〇a產生之光線經過覆蓋開孔162之彩色 透光膜180朝向支稽結構16〇之背面投射。光線的色彩會因 ’ 為彩色透光臈180的顏色而改變。 值得注意的是’在本實施例中,支撐結構160之本體161 内部的空間並具有—開口 164,位於支騎構16()之侧面。 彩色透光膜180係沿著圖令之箭頭方向,透過此開口 164安 裝於支撐結構16G之本體⑹内。並且,制者可以抽換裝 叹於支撐結構16G之本體161内的彩色透細18G,來調整 • 夜燈的顏色。

如第3A圖所示,在本實施例中,作為發光裝置mo之 光源的發光二極體陣列146。係設置於導光板144之長邊側, 對應於導光板144之長邊的側面。不過,本發明並不限於此, 就一實施例而言’發光二極體陣列丨46亦可設置於導光板144 之短邊側,對應於導光板144之短邊的侧面。同時,本發明 亦不限於使用單一個發光二極體陣列146。本實施例之發光 • 裝置140可使用二個以上的發光二極體陣列146,就一實施 例而言,當所使用之發光二極體陣列146的數量為二,此二 個發光二極體陣列146可設置於導光板144之相對兩側。 第4圖係發光二極體146之驅動電路一實施例的示意 圖。請參照第3A圖所示,此發光二極體陣列〗46具有交錯 排列的複數個第一發光二極體元件X與複數個第二發光二極 體元件Y。第一發光二極體元件X與第二發光二極體元件γ 之色溫不同。透過調整第一發光二極體元件X與第二發光二 ❿ 極體元件Y的發光亮度比例,即可達到改變照明色溫的目的。 同時請參照第4圖,雖然該些第一發光二極體元件X與 該些第二發光二極體元件Y是交錯排列於發光二極體陣列 146 ’不過’就電路連接而言,該些第一發光二極體元件X 則是在電性上連接成串’該些第二發光二極體元件γ也是在 電性上連接成串。 如第4圖所示,本實施例之驅動電路2〇〇包括一功率級 220與一控制級240。其中,功率級220係將外界之輸入電壓 201005203 轉換為電流信號,動第-發光二極體元件χ與第二發光 -極雜70件Υ。控制級240具有—第—定魏控制器242、 —第二定電流控制器244與一色溫亮度控制單元246。其中, 第-定電流控制器242與第二定電流控制器244係用以分別 控制流經該些第-發光二極體元件χ與缝第二發光二極體 元件Υ之電流值。色溫亮度控制單元246係依據外界輸入之

控制單元246大幅調降白光發光二極體元件X的發光亮度, 並同時僅小幅調降太陽色發光二極體元件Υ的發光亮度,以 使整體的發光色彩呈現偏黃色。 在本實施例之發光裝置140中,僅使用二種不同色溫的 發光二極體元件Χ,Υ,因此,在驅動電路200中僅搭配有第 12 201005203 一定電流控制器242與第二定電流控制器244,以分別控制 • 流經第一發光二極體元件x與第二發光二極體元件γ的電流 .

導光板144的一侧,發光裝置14〇的厚度只需要大於導光板 13 201005203 144即可,因此,本實施例之發光裝置HO有助於達到薄型 • 化的目的。本實施例之光學膜片145可為菱鏡片、擴散片或 , 是其他光學膜片,以調整發光裝置140之發光面14〇a的發光 光形,防止眩光產生。 其次,傳統的發光二極體檯燈10能調整發光亮度但無法 調整照明色溫。相較之下,如第4圖所示,本發明之實施例

Description of the Invention: [Technical Field] The present invention relates to a desk lamp, and more particularly to a desk lamp using a light emitting diode (LED) as a light source. [Prior Art] A high-efficiency luminescent light-emitting element that converts electrical energy into light energy is also a tiny solid-state light source (solidstateiUuminat〇r). The main component of the light-emitting body is a semiconductor p_n junction structure. After a voltage is applied across the P-n junction to apply current, electrons and holes are generated, and electrons and holes flow to and combine with the p-n junction to release photons. Fig. 1 is a schematic view of a floor lamp typically using a light-emitting diode element as a light source. As shown in the figure, the lamp 10 has a base 12, a light-emitting device 14 and a support structure 16. It is such that the support structure 16 is used to support the light-emitting device 14 at a certain height above the base 12. Illumination device 14 has a light emitting surface 14a to provide illumination. The light-emitting device 14 has a plurality of light-emitting diode elements 14b as light sources. These light-emitting diode elements 14b are directly disposed on the light-emitting surface Ma for illumination. Note that I, since the light-emitting diode element (10) is directly disposed on the light-emitting surface 14a, the thickness of the light-emitting device 14 must be at least added to the light-emitting diode element 14b in order to improve the light-emitting brightness and uniformity of the light-emitting surface 14a. The thickness of the optical structure (eg lens structure) to be placed. Therefore, such a light-emitting device 14 is generally difficult to meet the requirements for thinning. Secondly, since the illuminating device 14 is disposed on the same plane by the illuminating dipole element 14b which emits more light, the surface light source generates a light effect of 5 201005203, and therefore, it is difficult to avoid uneven light intensity. The problem may even be that the image of each of the light-emitting diode elements 14b appears in the illumination of the light-emitting surface 14a. In addition, the use of the plurality of light-emitting diode elements 14b to produce the light-emitting effect of the surface light source may also result in the generation of multiple images, and even some of the light may be directly projected onto the user's eyes to cause discomfort to the user. SUMMARY OF THE INVENTION An embodiment of the present invention provides a light-emitting diode table lamp that can achieve the purpose of thinning a light-emitting device, and can also avoid the disadvantage that the light-emitting intensity is not uniform. An embodiment of the present invention provides a light-emitting diode floor lamp having a night light function. An embodiment of the present invention provides a light-emitting diode table lamp that can adjust the color temperature of the illumination according to the needs of the user. Other objects and advantages of the present invention will become apparent from the technical features disclosed herein. • Embodiments of the present invention provide a light emitting diode table lamp for one or a portion or all of the above or other purposes. The LED table lamp comprises a base, a lighting device, a supporting structure and a triggering device. Among them, the light emitting device has a light emitting surface. The bottom end of the support structure is pivotally coupled to the base, and the top end is pivotally coupled to the illumination device. Moreover, the support structure has a body corresponding to the light-emitting device, and the body has at least one opening, and the triggering device corresponding to the light-emitting surface of the light-emitting device is disposed between the support structure and the light-emitting device. When the light-emitting device is covered by the body of the support structure, the light generated by the light-emitting surface is projected toward the back surface of the support structure via the opening, while the trigger device is triggered to reduce the light-emitting brightness of the light-emitting surface. In an embodiment of the invention, the light emitting device has a housing, a light guide plate, at least one optical film, and at least one light emitting diode. The light guide plate is disposed in the housing, and the light guide plate has a light incident surface and a light exit surface connected to the light incident surface. The optical film is disposed above the light emitting surface of the light guide plate. The light-emitting diode system is adjacent to the light-incident surface of the light guide plate. The light emitted from the light-emitting diode enters the light guide plate through the light incident surface and is emitted from the light exit surface to the optical film, and a light source is formed via the light emitting surface. In one embodiment of the invention, the illuminating device is provided with two different color temperature illuminating diode elements. And the 'light-emitting diode lamp has a drive circuit. The drive circuit has a power stage and a control stage. The power stage provides current to drive the LED components within the illumination device. The control stage has a first constant current controller, a second constant current controller and a color temperature control unit. The color temperature brightness control unit can respectively control the current values of the light emitting diode elements flowing through the two different color temperatures through the first constant current controller and the second constant current controller according to the input control signal. In one embodiment of the invention, the light-emitting diode lamp has a color light transmissive film mounted in the body of the support structure and covering the opening. This color translucent film can change the color of light that is projected outward through the aperture. Conventional light-emitting diode lamps directly place a plurality of light-emitting diode elements on a light-emitting surface to provide illumination, which may cause the light-emitting device to be less thinned, and may cause a problem of uneven luminous intensity. In contrast, the light generated by the light-emitting diode of the embodiment of the present invention is uniformly mixed in the light guide plate, and then projected outward through the optical film, thereby avoiding the problem of uneven light intensity 7 201005203 And help to achieve the purpose of thinning. Secondly, the traditional light-emitting diode table lamp can usually only adjust the brightness of the light and cannot adjust the color temperature of the light. In contrast, the light-emitting diode lamp of the embodiment of the present invention has a color temperature, and the unit can be adjusted according to the control number, through the first constant current controller and the second constant current control. The current magnitude and proportion of the light-emitting diode component of the single-color temperature to change the illumination color temperature of the light-emitting surface. In addition, when the illuminating two-pole illuminating device of the embodiment of the present invention is attached to the support structure, the trigger device is triggered _ the hairline of the hair drop. At the same time, the light generated by the light-emitting surface is projected through the colored light-transmissive film toward the back of the branch structure, and the color illumination is provided for the night illumination. The advantages and spirit of the present invention will be further understood from the following detailed description of the invention. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. The directional terms mentioned in the following embodiments, such as "up, down, left, "right, front or back, etc." are merely directions referring to the additional drawings. Therefore, the terminology used is used to describe that it is not intended to limit the invention. The second and second drawings are schematic views of an embodiment of the light-emitting diode table lamp of the present invention. As shown in the figure, the light-emitting diode lamp 1A includes a base 120, a light-emitting device 140, a support structure 160 and a triggering device (not shown). Wherein the light-emitting device 140 has a light-emitting surface 140a. The illuminating device 140 is pivotally coupled to the top end of the support structure 160 through the rotating shaft 190. The bottom end 160b of the wrap structure 160 is pivotally coupled to the base 120 to maintain the illumination device 140 at a height above the base 120. 8 201005203 The support structure 160 has a cover 61 corresponding to the light-emitting device 14 . The body 161 has at least one opening 162 corresponding to the light-emitting surface 140 a ′ of the light-emitting device 14 and penetrates the body 161 of the support structure 160 .

As shown in Fig. 3A, in the present embodiment, a light-emitting diode array 146 is used as a light source of the light-emitting device mo. It is disposed on the long side of the light guide plate 144 and corresponds to the side of the long side of the light guide plate 144. However, the present invention is not limited thereto. In one embodiment, the light-emitting diode array 46 may be disposed on the short side of the light guide plate 144, corresponding to the side of the short side of the light guide plate 144. Also, the present invention is not limited to the use of a single light emitting diode array 146. The illuminating device 140 of the present embodiment can use two or more LED arrays 146. In one embodiment, when the number of illuminating diode arrays 146 is two, the two illuminating diodes The arrays 146 can be disposed on opposite sides of the light guide plate 144. Fig. 4 is a schematic view showing an embodiment of a driving circuit of the light-emitting diode 146. Referring to Fig. 3A, the LED array 46 has a plurality of first light emitting diode elements X and a plurality of second light emitting diode elements Y arranged in a staggered manner. The color temperature of the first light-emitting diode element X and the second light-emitting diode element γ are different. By adjusting the ratio of the luminance of the first light-emitting diode element X and the second light-emitting diode element Y, the purpose of changing the illumination color temperature can be achieved. Please refer to FIG. 4, although the first LED component X and the second LED components Y are staggered in the LED array 146 'but' in terms of circuit connection, The first light-emitting diode elements X are electrically connected in series. The second light-emitting diode elements γ are also electrically connected in series. As shown in FIG. 4, the driving circuit 2A of the present embodiment includes a power stage 220 and a control stage 240. Among them, the power stage 220 converts the external input voltage 201005203 into a current signal, and moves the first-light-emitting diode element 第二 and the second illuminating----------- The control stage 240 has a first-order controller 242, a second constant current controller 244, and a color temperature control unit 246. The first constant current controller 242 and the second constant current controller 244 are configured to respectively control current values flowing through the first light emitting diode elements and the second light emitting diode elements. The color temperature brightness control unit 246 transmits the current flowing through the first light emitting diode element X and the second wave through the first constant current controller 242 and the second constant current controller 244 according to a control signal input from the outside. The magnitude and proportion of the current of the photodiode element γ to adjust the illuminating brightness and the illuminating color temperature. At the same time, please refer to FIG. 2 . In an embodiment, when the light-emitting device 14 is covered by the body 161 of the support structure 160 , the trigger device is triggered to pass through the color temperature brightness control unit 246 to adjust the brightness of each light. The polar body element Χ, the illuminating brightness of the Υ, to reduce the overall illuminating brightness of the light emitting surface 140a. However, the invention is not limited to this. In another embodiment, the color temperature and brightness control unit 246 does not adjust the brightness of each of the light emitting diode elements Χ, γ, and the first light emitting diode element X and the second light are simultaneously transmitted. The brightness ratio of the diode element ' is used to adjust the color temperature of the illumination. For example, the first light-emitting element X may be a white light-emitting diode element, the second light-emitting diode element may be a solar-colored light-emitting diode element, and the trigger device is greatly adjusted by the color temperature brightness control unit 246. The illuminating brightness of the white light emitting diode element X is lowered, and at the same time, the illuminating brightness of the solar illuminating diode element Υ is only slightly adjusted, so that the overall illuminating color is yellowish. In the light-emitting device 140 of the present embodiment, only two light-emitting diode elements of different color temperatures are used, and therefore, only the 12th 201005203 constant current controller 242 and the second constant current control are matched in the driving circuit 200. The device 244 is configured to respectively control a current value flowing through the first light emitting diode element x and the second light emitting diode element γ. However, the present invention is not limited thereto, and in one embodiment, if the type of the light-emitting diode elements used is increased to three or more types, a corresponding constant current controller is added to the drive circuit 200. Next, in the present embodiment, the first light-emitting diode element X and the second light-emitting body element Y having different color temperatures are staggered in one light-emitting diode array 146. However, the present invention is not limited thereto, and in one embodiment, if the number of the light-emitting diode arrays 146 used is increased to two, the first light-emitting diode element X and the second light-emitting element may be used. The diode elements γ are respectively disposed on the two LED arrays 146.

As shown in Fig. 1A, a conventional light-emitting diode lamp 1b directly places a plurality of light-emitting diode elements 14b on the light-emitting surface 14a to provide illumination, which causes the light-emitting device 14 to be less thinned. Further, since the light-emitting device 14 is provided with a plurality of light-emitting diode elements 14b that emit light that emits a point source on the same ® plane to generate a light-emitting effect of the surface light source, it is difficult to avoid the problem of uneven light intensity.

After the inner portion is uniformly mixed, it is projected outward through the optical film 145 and the light-emitting surface 140a, so that the problem of unevenness in light thinness can be avoided. At the same time, since the light-emitting diode light bar 146 is disposed on one side of the light guide plate 144, the thickness of the light-emitting device 14〇 only needs to be larger than the light guide plate 13 201005203 144. Therefore, the light-emitting device HO of the embodiment is helpful to achieve The purpose of thin type. The optical film 145 of this embodiment may be a diamond lens, a diffusion sheet or other optical film to adjust the illuminating shape of the light-emitting surface 14 〇 a of the light-emitting device 140 to prevent glare.

And color temperature Φ brightness control unit 246. The color temperature brightness control unit 246 adjusts the current flowing through the first light emitting diode element X and the current of the second light emitting diode element γ through the first constant current controller 242 and the second constant current controller 244 according to a control signal. The size and proportion of the light can change the illumination color temperature of the light-emitting surface 140a to match different environments. In addition, as shown in FIG. 2A, when the light-emitting device 140 of the light-emitting diode table lamp 100 of the embodiment of the present invention is attached to the body 161 of the support structure 16〇, the trigger device is triggered to lower the light-emitting surface 14〇. The brightness of a light enters the night light mode. Moreover, the LED housing lamp 100 of the present embodiment has a color light transmissive film 180 disposed in the body (6) of the support structure 160 and covering the opening 162 of the body 161 of the support structure 160.
