New description: [New technical field] • This creation is about a luminaire, especially a luminaire that uses a side-lit ‘Side View LED as a light source. [Prior Art] In recent years, due to the continuous improvement of high-power light-emitting diodes (LEDs), white-light bulbs and fluorescent lamps have been gradually replaced in many fields, for example, traffic numbers - lamps, lighting equipment, and lamps. For example, in the case of a luminaire, LED is often used as a light source because the LED has a strong directivity and can emit a uniform light mixture to form a uniform surface light source. Referring to Figure 1, there is shown a cross-sectional view of a conventional internal structure of the luminaire. The internal structure of the luminaire includes a plurality of front-illuminated LEDs 15 , a light panel 25 ′ — a light guide 5 , a reflector 1 〇 , and a heat sink 35 . The LEDs 15 are disposed on one surface of the light panel 25 . The light-emitting surface 12 of the LEDs 15 is parallel to the extending direction of the surface of the light-emitting panel 25 and contacts the light-guiding plate as the luminous efficiency and heat dissipation problem of the general high-power LED, as shown in FIG. Most of the input power will be converted into heat dissipation, and the heat dissipation area of the light board 25 carrying the LEDs 15 is small, so that the heat sink 35 must be added to the other surface of the light board 25 to improve the heat dissipation capability, but The volume occupied by the heat sink 35 is actually much larger than the volume of the LED, and the space occupied by other components such as the control circuit will cause the structural design of the lamp to be thinned and the design of the shape limited, and Using more parts will result in higher production costs. [New content] The purpose of this creation is to provide a lamp structure that not only achieves thinness and heat dissipation, but also simplifies the structure and saves component costs. 3 M413811 In order to achieve the above-mentioned creative purpose, the lamp according to an embodiment of the present invention comprises at least one LED, a heat sink, a light guide and a reflector, wherein the LEDs are used as lamps Illuminating light source. The heat dissipation lamp board has a first surface and a second surface 'a light source for mounting the electronic component and the at least one LED, and at the same time providing a heat dissipation function for the at least one LED light source, wherein the at least one LED The light emitting surface is perpendicular to the first surface and the second surface of the heat dissipation lamp board. The light guide plate is disposed on the heat dissipation lamp board and contacts the light emitting surface of the at least one LED to guide the light emitted by the at least one ui into a light source of one light source. The reflector is disposed on the heat dissipation lamp plate for diverting light transmitted through the light guide plate to the outside of the lamp. According to the luminaire of the present invention, the at least one LED includes a plurality of LEDs extending evenly around the first surface of the heat sink to obtain a uniform light source. According to the luminaire of the present invention, the components of the luminaire are used as much as possible to achieve the purpose of thinning the overall structure. The reflector can be a reflective metal coating layer or a reflective metal coating layer. Too much space. According to the luminaire of the present invention, in which the material of the heat-dissipating lamp board is used, we can use a material with high heat dissipation capability such as a ceramic substrate or a metal substrate, and the heat-dissipating lamp plate has a large heat-dissipating area, thereby increasing the heat-dissipating ability of the lamp to replace the s It is known that the heat dissipation method of the heat sink is utilized, and at the same time, the simplified and thinned structure is achieved, thereby reducing the component cost. According to the luminaire of the present invention, the specific electronic component such as the power control component and its associated wiring may be disposed on the second surface of the heat dissipation lamp board, thereby increasing the space utilization rate. A luminaire according to another embodiment of the present invention may be constructed by using a double-sided smear sap juice. The structure comprises at least two sets of LEDs, a heat sink, two sets of light guides, and two sets of reflectors. The LEDs on the first surface and the second surface of the heat-dissipating lamp board can be controlled by the control unit located outside the lamp structure, so that the M413811 can selectively determine single-sided light emission or double-sided light illumination for use in combination. Demand, so it is more convenient to use. [Embodiment] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

The other lower surface is provided with a number of electronic components (such as power control components) and associated traces. Not shown) to control the luminescent properties of the LEDs 20. In this embodiment, since the heat dissipation lamp plate 30 is a ceramic substrate or a metal substrate having a high thermal conductivity, the upper and lower surfaces of the heat dissipation lamp plate 3 have a large heat dissipation area, so that the heat dissipation lamp plate 30 is The upper and lower surfaces can simultaneously provide heat dissipation to the LEDs, without the need to add additional heat dissipating components as is known in the art. Referring to FIG. 5, a side view of the combination of the light guide plate 5, the LEDs 20 and the heat sink 30 in the lamp 72 of FIG. 2A is shown, wherein the ud 20 is along the upper surface of the heat sink 30.
