Description of the invention: [Technical field to which the invention pertains] * The present invention relates to a lighting device, and more particularly to a lighting device for a body. [Prior Art] Light Emitting Diode (LED) has the characteristics of environmental protection, mechanical reliability and high service life. Therefore, the use of Lu as a light source for lighting devices is a new trend. Please refer to FIG. 1, which is a conventional elongated LED lighting device 10 (hereinafter referred to as "LED lighting device"). The LED lighting device includes a light box 11, a circuit board 12, a plurality of side-light LEDs 13, a reflective element 14, a plurality of reflective sheets 15, and a diffusion sheet 16. The light box n is a hollow elongated frame structure having an opening 112. The circuit board 12 is also elongated and correspondingly disposed at the bottom of the light box 11. The plurality of edge-lit LEDs 13 are electrically connected to the upper surface of the circuit board 12. The reflective element 14 is also a box structure that can be inserted into the light box 11 by the opening 112 accordingly. The reflective member 14 has a plurality of mutually connected side walls 142 and a bottom reflecting plate 144, and the inner surfaces of the side walls 142 and the bottom reflecting plate 144 are reflecting surfaces. The bottom reflecting plate 144 is provided with a plurality of through holes 146 corresponding to the plurality of LEDs 13. The light exit portions of the plurality of LEDs 13 pass through the plurality of through holes 146, respectively. The plurality of reflection sheets 15 are correspondingly disposed at the top of the plurality of lEDs 13. The diffuser 16 is capped at the opening 112 of the light box n. The light beam emitted by the plurality of lEDs 13 is reflected by the side wall 142 of the reflective element 14 or the bottom surface reflection plate 144 and finally exits through the diffusion sheet 16. However, although the design of the ED 13 and the anti-1313336 film 15 is adopted in the above LED lighting device 10, the distance between the LED 13 and the diffusion sheet i6 (10) can be appropriately reduced, but there is still a need between the LED 13 and the diffusion sheet 16. A larger distance can ensure that the light emitted from the diffusion sheet W is hooked, so the volume of the coffee device Zhao is not easy to be further reduced, and it is difficult to adapt to the development trend of the product:,. 『< [Summary of the Invention] In the above, it is necessary to provide a small-sized illuminating device. An LED lighting device comprising: (4) a circuit board, at least one light-emitting diode electrically connected to the circuit board, a reflective element, and a lamp cover.

The light box comprises an upper cover, a cover opposite the upper cover, a side wall connecting the upper and lower covers of the plurality of fish, and an opening formed in one of the side walls. The circuit is located at the lower cover of the light box. The portion of the light-emitting side of the at least one light-emitting diode faces the opening of the wire box, and the top surface faces the upper cover. The reflective element is located in the light box, and the light generated by the reflective light emitting diode is emitted from the opening. The lamp cover is capped to the opening. In the above LED lighting device, since the light-emitting side of the coffee is oriented toward the second side, the top of the mouth is facing from the upper surface of the light box, so that the light box is fully utilized in the horizontal direction, and the space of the light box in the thickness direction is obtained. It is easy to make the LED lighting device have a smaller volume, and the development direction of the electronic product is lighter and shorter; in addition, when the LED lighting device is required to have a uniform surface light source, the space of the light box in the horizontal direction is sufficient. Therefore, it is also easy to ensure that there is enough 1313336 distance between the LED and the lamp cover to avoid the LEDs from being reflected and mixed on the lamp cover to generate bright spots.

The reflective assembly 24 includes an upper reflector 241 and a reflector opposite the upper reflector 241. 243, a plurality of side reflectors 245 extending upward from the edge of the lower reflector 243, and a plurality of through holes 247 formed in the lower reflector 243. The upper reflector 241, the lower reflector 243 and the side reflector 245 are combined to have a The opening 217 of the light box 21 has a corresponding opening structure. Each of the through holes 247 corresponds to each of the LEDs 23. In this embodiment, the top surface 235 and the side surface 233 of the LED 23 pass through the through hole 247, respectively, and the reflection assembly 24 The lower reflector 243 1313336 is mounted on the base 231 of the LED 23.

It can be understood that the mask 27 can also be directly fixed to the surface of the lamp cover 25 facing the LED 23 or the light exit side 233 of the LED 23. In the LED lighting device 20, since the light-emitting side surface 233 of the LED 23 faces the opening 217 of the light box 21, the top surface 235 faces the upper cover 211 of the light box 21, so that the length space of the light box 21 in the X direction (ie, the horizontal direction) is fully utilized. The height space of the light box 21 in the Y direction (i.e., the thickness direction) is reduced, so that the LED lighting device 20 is easy to have a smaller volume, and is adapted to the development direction of the light and thin electronic products. In addition, when the LED illumination device 20 requires a uniform surface light source, since the length of the light box 21 in the X direction is fully utilized, it is also easy to ensure sufficient spacing between the LED 23 and the lamp cover 25 to prevent the LED 23 from being reflected. The mixed light exits the lamp cover 25 to produce a bright spot. It can be understood that when the LED lighting device 20 is applied to far field illumination, the lamp cover 25 can also be a transparent plate. The reflective component 24 can also be coated on the inner surface of the cover 211 and the side wall 215 of the light box 21 and the upper surface of the circuit board 22 1313336.
