Description of the Invention: [Technical Field to Which the Invention Is Ascribed] The present invention relates to a lamp unit. The invention also relates to an illuminator comprising at least one of the lamp units. [Prior Art] A conventional lamp unit such as an incandescent lamp or a white hot wire lamp is generally adapted to 'only emit white light. To emit colored light, a subtractor can be provided to the lamp. The Phillip NightGuide lamp is an example of a lamp unit suitable for emitting white light in a __ direction and emitting a cyan light in a second direction and emitting a yellow-white light in a third direction. In order to achieve this effect, the guilty person has a white light source and a number of colored coatings for properly manipulating the white light. The NightGuide lamp is dedicated to automotive applications. One of the characteristics of the NightGuide is that the color filter reduces the efficiency of the lamp. Another feature is that the effect is static. In order to change this effect, the lamp needs to be replaced. In addition, patent document BE-1015507 discloses a luminaire for providing colored light and white light in different directions. The luminaire comprises two or more kinds of white light, at least one of which is not bright and is provided with a separate enamel for each light on one side and no (different) color filter on the other side. However, one of the disadvantages of this luminaire is that one must replace the conventional illuminator with the luminaire so that the colored light and white light are in different directions. SUMMARY OF THE INVENTION The purpose of this month is to at least partially overcome at least one of the above mentioned problems and disadvantages and to provide a solution for providing different light improvements in different directions. 140523.doc -4* 201009237 It will be apparent from the following description that this and other objects can be achieved by the present invention and other illuminators in accordance with the present invention. a lamp unit comprising: at least one light source comprising: a lamp first light; and at least a second wave adapted to emit the first wavelength spectrum having a first wavelength spectrum The emitting one has - unlike the second light configured to be at least "all", wherein the light unit emits the first light upward and a second light in at least the other direction. The force thus provides a combination of the first light and the second light in different directions in the lamp unit, b ^ 提供 providing the dual functionality of the luminaire or the fixture level. In other words, the w^' lamp is configured to pass itself (rather than the illuminator) such that during the operation, the first second light is emitted in at least the direction and the illumination is emitted. This makes it possible to retrofit a conventional refurbishment lamp in the existing beta, so that it is advantageous to provide the first light and the second light in different directions without replacing the entire illuminator. In addition, the independent light source to emit the first light and the second light facilitates independent control of the first light and the second light. " Preferably, the first light is white light (wide spectrum) and the second light is colored light (small spectrum). Alternatively, the first light may be colored light, but the color is different from the color of the second light. It is also preferred that the socket is adapted to be mounted in a socket, preferably a standard socket. This allows the lamp unit to be reinstalled in a conventional luminaire or luminaire having such a light socket. The standard lamp socket can be, for example, a conventional screw socket or a bayonet socket. In the case of a screw socket 140523.doc -5- 201009237, the lamp holder is a conventional threaded socket with several suitable threads. The direction of the emitted light can be determined by appropriately selecting at least one of the primary optics of the light sources, the orientation of the light sources, and the secondary optics of the light unit such that during operation, the first (eg, white) light is emitted in the at least one determined direction, and the second (eg, colored) light is emitted in at least another direction. Here, a plurality of primary optics are adapted to be directly emitted from the source and are typically incorporated into the source package, and a plurality of secondary optics are typically placed outside of the source envelope and are adapted Light that is emitted from the source and that has been manipulated by the primary optics is manipulated. Such manipulations may, for example, include orientation, reorientation, alignment, reflection, and the like. It is advantageous to use the optics and orientation to determine the direction of the emitted light, as it allows the other parts of the lamp unit to be constructed directly and relatively simply, without the need for any particular design of secondary optics. On the other hand, the use of the secondary optics determines that the direction of the emitted light is repulsive (4) because it allows for more precise control of the direction of the emitted light. In an embodiment, the at least one first light source comprises a plurality of primary optics adapted to direct the first light to the at least one determined direction, and the at least one second light source comprises a plurality of suitable second Light is directed to the primary optics in at least the other direction. For example, the at least one first light source can have a plurality of primary optics for side emission, and the at least one second light source has a plurality of primary optics for top emission to generate, for example, laterally relative to the socket Align the white light with the upwardly aligned colored light. In another embodiment, the light sources are directional light sources, wherein the at least first light source is oriented such that the first light is emitted in the at least one determined direction, and the at least one The two light sources are oriented to emit the second light in the at least one other direction. The directional light source is a light source suitable for generally emitting light in a certain direction or having a limited output angle, such as a top emitter, in contrast to an undirected emitter. In an exemplary variation of this embodiment, the light sources are top emitters, and the at least one first light source is oriented such that white light is aligned to the left relative to the socket, and the at least one second source is Oriented to align the colored light to the right relative to the socket.

In particular, the lamp unit 10 of FIG. 3 includes a side-emitting WLED 16 adapted to emit white light, a side emitting LED 38 adapted to emit a first color of light, and a side emitting LED adapted to emit a second color of light. 40. The second color may be the same or different from the first color. The LEDs can be disposed, for example, in a plurality of centrally located apertures 42, 44, 46 in the light guides, as illustrated. Therefore, the LEDs 16, 38, 40 are also stacked on each other. Each of the light guides further includes a circumferential outcoupling facet 48, 5, 52, wherein the orientation of the facets determines the direction of the light. The facet 48 is oriented at about -45 degrees with respect to the lamp axis 54. The facet 5 is parallel to the lamp axis "and the facet 52 is oriented at about 45 degrees relative to the lamp axis 54. In operation of the lamp unit ίο, the light from the white LED 16 is coupled into the light guide 32 and will be reflected by the TIR at the light guide_air interface of the facet 48 to the light guide. The lower side, because the light is at right angles or nearly right angles to the lower side, the light will overcome the TIR on the lower side of the light guide member, and thus the guide is coupled via the lower side of the light guide member The light member 32 is guided downwardly as depicted by the exemplary ray trace 56. Similarly, light from the color LED 40 is coupled into the light guide 36 and will be guided, as illustrated by the exemplary ray trace 58. On the other hand, most of the light from the color LED 38 coupled into the light guide 34 will be at right angles or almost due to the light and the facet 5 〇 140523.doc -12- 201009237 : At right angles, the facets 50 are directly joined and the mouth is guided to the side, as exemplified by the exemplary ray ray 6G.

The light unit 10 includes a plurality of optical elements that direct and direct light from different directions to different directions. In particular, the lamp unit 1 of Figure 4 includes at least one centrally disposed LED 62 adapted to emit colored light, the LEDs 62 being surrounded by a circle of LEDs 64 suitable for emitting white light. The LEDs 62 and 64 are preferably top emitters. In addition, the lamp unit 10 includes at least one TIR element 66 that is shaped and clamped to align colored light from the LED 62 and redirect white light from the looped white LED 64 to the side. The directions are as depicted by the exemplary ray traces 68 and 70, respectively. The at least one TIR element 66 can be, for example, a funnel shape, and can be provided with one or more air outlets on one of the non-hollow, lenticular light guides 72 disposed on the LEDs, wherein the funnel is placed therein ( These) are centered on colored led. Alternatively, the TIR elements can be used instead of the one or more metal reflectors and the results are similar. The light guide 72 can be made, for example, of transparent or translucent plastic or glass. In yet another embodiment (not shown) of the lamp unit, all 140523.doc 13 201009237 LEDs of the lamp unit are multi-die LEDs (e.g., R (JB or rgbw dies) for use in all directions. In a manner, only white light or only colored light can be produced in all directions, but by appropriately and selectively activating the dies of the different LEDs, the same light unit (with another setting) can still be used to generate Directional white light and colored light. This embodiment is indeed extremely flexible, but additional control is required, as will be explained further below. In another embodiment (not shown), the lamp unit comprises an aluminum cube, The base of the cube is configured to face the socket. At least one color top emitting LED is mounted on top of the cube, and at least one self-color top emission is mounted on each of the four sides of the cube The light from the LEDs is thus directed in five orthogonal directions. The aluminum cube provides good thermal contact. Furthermore, the light sources of the 'secret unit are movable relative to the lamp holder so that even the lamp The seat is mounted in a specific orientation (for example, in the case where the socket is a screw type and the socket is mounted on a screw socket), the direction of the emitted light can still be changed. In the example, the lamp unit includes an inner bayonet coupling 'to attach the socket to other portions of the lamp unit' to allow a user to rotate other portions of the lamp unit, including the light source, even if the lamp The seat is fixed. In other embodiments, the direction of the light source can be electronically motorized. Figures 5a-5b are viewed primarily from the sides of a plurality of illuminators or luminaires comprising a lamp unit in accordance with the present invention. Figure 5a shows a chandelier illuminator hanging on a ceiling 76. The illuminator 74 includes a plurality of colored ambient lights u towards the ceiling 76, 140523.doc -14 - 201009237 and in other The direction of the "normal" white function light or the light of the working light 84 is 1 〇. The lamp units 1 in the illuminator 74 are advantageously mapped in the figure or 4 and described with respect to FIG. 1 or 4. Type of illuminator. For these lights The illuminator (not shown) in which the elementary system is installed upside down requires several light units that emit "down" colored light. "This can be done, for example, by the lamp unit of Figure 3. The white LED replaces the colored LEDs to achieve, and vice versa. Lutu 5b shows a platform illuminator 78 that hangs from a ceiling 8 to a floor 86. The illuminator 78 includes a plurality of ceilings 8 A color ambient light 82 is emitted, and a "normal" white functional light or a working light lamp unit 10 is emitted toward the floor 86. Since the lamp units are placed laterally in the illuminator, several are required to be on one side. A white light unit is emitted. Thus, a lamp unit of the type shown in Fig. 2 and described with respect to Fig. 2 can be advantageously used in the illuminator 78. In some embodiments of the invention, all of the light source units of the lamp unit are turned on/off by a regular light switch associated with the socket in which the lamp unit is mounted. However, any of the above-mentioned lamp units 1 可 may further comprise a controller (not shown) adapted to selectively control the at least one light source suitable for emitting white light and the at least one suitable for emitting color Light source. That is, the white light and the colored light system can be controlled independently of each other to produce a desired illumination or illumination effect, for example, in a door. Several settings for the light source and the emitted light (the settings are controlled by the controller) can include on/off, dim or intensity level, saturation, color temperature, and color or color. 140523.doc 201009237 In an embodiment, the light unit can include a wireless receiver that is consuming or formed as part of the controller, wherein one of the wireless receivers communicates with the controller The remote control is used to selectively control the different light sources of the lamp unit. The controller and the wireless receiver are driven by a regular power source of the lamp unit, i.e., by electrical power provided via the lamp socket in which the lamp unit is placed. Therefore, as long as the =h unit is "substantially" turned on-- the user can use the remote control to selectively operate the different colors of the lamp unit by the rule switch associated with the lamp socket (four). In another embodiment, the controller is adapted to selectively control the light source suitable for emitting white light in accordance with an order of one of a plurality of power switches or on/off switches provided to the lamp unit Issue the light source of color light. - The way to accomplish this is to use a turn-on/off-human south voltage IC that identifies the lamp unit. Each time the -lamp light switch is used to turn the light unit off or on, the light unit is switched to the next setting. For example, as shown in Fig. 6, when the lamp unit is first turned on (step si〇), only the at least one light source suitable for emitting white light is on (step S/2). Only at least one light source suitable for emitting colored light is turned on after the lamp unit is turned off/on (step si4) (step si6). Then, after another closing/on sequence of the lamp unit (step S18), the at least one light source suitable for emitting white light and the at least one light source suitable for emitting colored light are both turned on (step S2〇) ^ After the next turn-off/turn-on switch, the s ^ loop is repeated and only at least one light source suitable for emitting white light is again on. 140523.doc 16 201009237 Other exemplary embodiments are discussed below. Here, the switch is a quick combination of turning on and off (using the rule light switch). In β, after a color cycle, the first switch turns on the white light and the second switch begins to change the color of the light emitted by the at least one light source suitable for emitting colored light. A switch now causes this sequence to stop at the desired color. In another operation, the first switch turns on the white light and the second switch begins a saturation cycle that can be stopped by a new switch at a desired saturation. ^ For such operations 'the lamp unit is better to remember the __ group setting, and when the lamp unit is turned on for a predetermined time (the predetermined time is longer than the: speed switching time), the lamp unit returns There are several settings on it. It is also possible to use a conventional dimmer wire that corresponds to all of the different settings of the white light source and the color light source, such as the intensity of the change, and the like. Those skilled in the art will recognize that the present invention is by no means limited to the preferred embodiments described above, and that many of the U and the variations can be made in the four (4) of the appended claims. For example, several other primary optics, the orientation of the sources, the source, and the plurality of line optics can be combined. At the same time, the LEDs suitable for emitting white light may be replaced by LEDs suitable for emitting colored light to provide, for example, - ambient light of a first color and a second working light of a different color.
