Description

本考案は、直管型LEDランプに関する。より詳しくは、本発明は、蛍光灯の代替品として有望視されている直管型LEDランプの新規な構造に関する。   The present invention relates to a straight tube type LED lamp. More specifically, the present invention relates to a novel structure of a straight tube type LED lamp that is regarded as a promising alternative to a fluorescent lamp.

従来から、家庭はもとよりオフィスやショッピングモール等の多くの場所において照明用器具として一般的に使用されている直管型蛍光灯は、内壁に蛍光物質を塗布したガラス管と、両端に取り付けられた電極(フィラメント)と、で構成されており、ガラス管は、空気を抜き真空にされ、少量の水銀とアルゴン等のガスが封入されている。   Conventionally, straight tube fluorescent lamps that are generally used as lighting equipment in many places such as offices and shopping malls as well as homes have been attached to both ends with glass tubes coated with fluorescent material on the inner wall. The glass tube is evacuated and filled with a small amount of gas such as mercury and argon.

このような直管型蛍光灯は放電灯の一種であり、電極間に電圧がかかると電流が流れて加熱された一方の電極から熱電子が放出し、放電が開始されて点灯する。より具体的には、一方の電極から放出して他方の電極に向かって飛び出した熱電子が、ガラス管内で蒸発して気体となっている水銀電子に衝突し、この衝突によって水銀電子が紫外線を発生する。そして、この紫外線がガラス管内に塗布された蛍光物質にあたることにより、可視光が発生して点灯するのである。   Such a straight tube fluorescent lamp is a kind of a discharge lamp. When a voltage is applied between the electrodes, a current flows and thermoelectrons are emitted from one of the heated electrodes, and discharge is started to light up. More specifically, the thermoelectrons emitted from one electrode and jumping toward the other electrode collide with mercury electrons that are evaporated and become gaseous in the glass tube. appear. Then, when this ultraviolet ray hits the fluorescent material applied in the glass tube, visible light is generated and turned on.

ところが、このような直管型蛍光灯は消費電力が多いとともに寿命が短く、環境や人体に悪影響を与え得る蛍光体を含み、また、使用される交流電源は一定の周波数を有することから、光に微弱な揺れを有し人の眼や脳に良くないとも言われている。このため、環境保護及び人体に対する安全性の観点から、かかる直管型蛍光灯の代替品として直管型LEDランプが提案されている(例えば特許文献1参照)。   However, such a straight tube fluorescent lamp has a high power consumption and a short life span, includes a phosphor that can adversely affect the environment and the human body, and the AC power supply used has a certain frequency, so that It is said that it has a slight shaking and is not good for human eyes and brain. For this reason, a straight tube type LED lamp has been proposed as an alternative to such a straight tube type fluorescent lamp from the viewpoint of environmental protection and safety to the human body (see, for example, Patent Document 1).

上記特許文献1には、図3に示すような、透明又は光拡散性を有する断面略円状の直管56の内部において、散乱細長板状基板55に複数のLED(発光ダイオード)素子54を列設し、両端部にはそれぞれ一般蛍光灯照明器具の両端部のソケットに適合する2本のピン端子112が設けられた、直管型LED蛍光灯の一般構造が開示されている。   In Patent Document 1, a plurality of LED (light emitting diode) elements 54 are provided on a scattering elongated plate-like substrate 55 inside a straight tube 56 having a substantially circular cross section having transparency or light diffusibility as shown in FIG. A general structure of a straight tube type LED fluorescent lamp is disclosed in which two pin terminals 112 that are lined up and both ends are fitted to sockets at both ends of a general fluorescent lamp illuminator, respectively.

実用新案登録第3142652号公報Utility Model Registration No. 3142652

しかしながら、上記特許文献1に記載のような一般構造の直管型LED蛍光灯では、LED素子54が発光に伴って熱を発生するところ、直管54の内部に熱がこもり、直管54、基板55、又は基板55の下部に位置する部材(図示せず)を変形させてしまったりして、直管型LED蛍光灯の寿命を損なうおそれがある。   However, in the straight tube type LED fluorescent lamp having a general structure as described in Patent Document 1, when the LED element 54 generates heat with light emission, heat is accumulated inside the straight tube 54, and the straight tube 54, There is a possibility that the life of the straight tube type LED fluorescent lamp may be impaired by deforming the substrate 55 or a member (not shown) located below the substrate 55.

そこで、本考案の目的は、直管型LEDランプにおいて、LED素子からの熱を管の内部に滞留させず効果的に外部に逃がし得る構造であって、管、基板又はその他の部材を熱変形させることがなく直管型LED蛍光灯の寿命を損なわない新規な構造を提供することにある。   Accordingly, an object of the present invention is a structure in which heat from an LED element can be effectively released outside without staying inside the tube in a straight tube type LED lamp, and the tube, substrate or other member is thermally deformed. An object of the present invention is to provide a novel structure that does not impair the life of a straight tube type LED fluorescent lamp.

本考案者らは、直管型LEDランプの構造について鋭意研究を重ねた結果、LED素子からの熱を有効に外部に逃がすためには、LED素子を設置した基板の形状を変更することは比較的困難であるが、当該基板を設置する土台となる部材の形状を変形することは比較的容易でかつ伝熱効果を高め得ることに着目し、鋭意検討の結果、本考案に到達した。   As a result of intensive research on the structure of a straight tube type LED lamp, the present inventors have compared the change of the shape of the substrate on which the LED element is installed in order to effectively release the heat from the LED element to the outside. Although it is difficult, it is relatively easy to change the shape of the base member on which the substrate is installed and the heat transfer effect can be enhanced.

また、上記本考案の直管型LEDランプにおいては、前記LED構造体に設けられた中空部が、管の外部に開放している部分(開放部分)を有するのが好ましい。   Moreover, in the straight tube | pipe type LED lamp of the said invention, it is preferable that the hollow part provided in the said LED structure has a part (open | release part) open | released outside the pipe | tube.

この開放部分は、直管型LEDランプの両端部において、そのまま外部に開放していてもよいが、通常直管型LEDランプの両端部には端子を有する端子部が設置されるところ、例えば当該端子部に上記中空部に連通する開口部を設けて、これを開放部分としてもよい。   This open portion may be open to the outside as it is at both ends of the straight tube LED lamp, but usually a terminal portion having terminals is installed at both ends of the straight tube LED lamp. The terminal portion may be provided with an opening communicating with the hollow portion, and this may be an open portion.

このような構成によれば、本考案の直管型LEDランプにおいて、基板上に設置されたLED素子が発熱したとしても、LED構造体に設けられた中空部を介して外部に熱を逃がすことができ、管、基板又はその他の部材を熱変形させることがなく直管型LED蛍光灯の寿命を損なうことをより効果的に防止することができる。   According to such a configuration, in the straight tube type LED lamp of the present invention, even if the LED element installed on the substrate generates heat, heat is released to the outside through the hollow portion provided in the LED structure. Therefore, it is possible to more effectively prevent the life of the straight tube type LED fluorescent lamp from being deteriorated without thermally deforming the tube, the substrate or other members.

<< Embodiment 2 >>
FIG. 2 is a schematic longitudinal sectional view of the straight tube type LED lamp 11 of the present embodiment (that is, a diagram showing a section that can be seen when cut from a plane substantially perpendicular to the length direction and viewed from the length direction). is there. As shown in FIG. 2, the straight tube type LED lamp 11 of the present embodiment has a long plate-like substrate 16, at least one LED element 18 installed on one surface of the substrate 16, and a length that holds the substrate 16. LED structure 20 comprised of a scale-shaped base 14, and straight tube 12 that forms an internal space with base 14 and encloses substrate 16 and LED element 18 in the internal space, and includes LED structure 20. Among them, the base 14 has a hollow portion 4 a and also has a second hollow portion (gap) 14 b between the base 14 and the substrate 16.

直管12には、土台14に対応する部分にスリットが設けられており(図示せず。)、ここに土台14が組合されることにより、両者で内部空間を形成し、当該内部空間に基板16及びLED素子18が内包される。また、直管12の両端には、図示しないが、それぞれ第一の開口部及び第二の開口部があり、例えば端子を有する板状乃至はソケット状の端子部が設けられている。   The straight pipe 12 is provided with a slit (not shown) in a portion corresponding to the base 14, and the base 14 is combined therewith to form an internal space therebetween, and a substrate is formed in the internal space. 16 and the LED element 18 are included. Moreover, although not shown in figure, the both ends of the straight pipe 12 have a 1st opening part and a 2nd opening part, respectively, for example, the plate-shaped or socket-shaped terminal part which has a terminal is provided.

この直管12は、例えばポリカーボネート等の樹脂又はガラスで構成されており、少なくとも図2における直管型LEDランプ11の上側(即ち、LED素子18が設けられていて光が出射する部分)に光を出射することが可能である。したがって、直管12は透明でも半透明でもよく、通常の蛍光灯のように、光散乱可能な材料を含んでいれば乳白色であってもよい。また、直管12の外表面には、出射光を散乱させてより広い部分を照射可能なように、例えば多数の平行溝を設ける等の加工をしてもよい。   The straight tube 12 is made of, for example, a resin such as polycarbonate or glass, and is at least lighted above the straight tube type LED lamp 11 in FIG. 2 (that is, the portion where the LED element 18 is provided and light is emitted). Can be emitted. Therefore, the straight tube 12 may be transparent or translucent, and may be milky white as long as it contains a material capable of scattering light like a normal fluorescent lamp. Further, the outer surface of the straight pipe 12 may be processed, for example, by providing a number of parallel grooves so that a wider portion can be irradiated by scattering the emitted light.

土台14は、例えばアルミニウムやアルミニウム合金によって形成されており、熱伝導性が高いものである。この土台14は、鋳造等によって容易に作製することができる。また、放熱性を高めるために、土台14の表面には、多数の平行溝を設けたり、微小なフィンを設けたりしてもよい。   The base 14 is made of, for example, aluminum or an aluminum alloy, and has high thermal conductivity. The base 14 can be easily manufactured by casting or the like. Moreover, in order to improve heat dissipation, many parallel grooves or minute fins may be provided on the surface of the base 14.

基板16には、例えばアルミ基板等の金属製基板、FRP、シリコーン樹脂等の基材の表面に銅箔を有する樹脂製基板、金属製基板と樹脂製基板との複合基板等の従来公知の基板を用いることができる。樹脂を用いる場合は、なかでもLED素子8が発熱する場合を考慮して、耐熱性樹脂を用いるのが好ましい。   The substrate 16 may be a conventionally known substrate such as a metal substrate such as an aluminum substrate, a resin substrate having a copper foil on the surface of a base material such as FRP or silicone resin, or a composite substrate of a metal substrate and a resin substrate. Can be used. In the case of using a resin, it is preferable to use a heat resistant resin in consideration of the case where the LED element 8 generates heat.

また、LED素子18としては、従来公知のものを用いることができるが、例えば砲弾型LEDでも矩形の高輝度型LEDであってもよい。   As the LED element 18, a conventionally known one can be used. For example, a bullet-type LED or a rectangular high-brightness LED may be used.

このような構成を有することから、直管型LEDランプ11では、基板16に設置されたLED素子18が発熱したとしても、LED構造体20のうちの土台14に設けられた中空部14a及び第二の中空部(隙間)14bに熱を逃がすことができ、直管12、基板16又はその他の部材を熱変形させることがなく直管型LEDランプ11の寿命が損なわれることを更に効果的に防止することができる。   With such a configuration, in the straight tube type LED lamp 11, even if the LED element 18 installed on the substrate 16 generates heat, the hollow portion 14 a provided in the base 14 of the LED structure 20 and the second LED element 18.
