The specific embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe the specific embodiment of the present utility model in detail.
Shown in Fig. 1~4, for the utility model provides a kind of preferred embodiment of LED panel light, comprise for the hard-wired top board 5 of LED panel light, be arranged on the pcb board 4 on the top board 5 and be arranged on top board 5 and pcb board 4 between power supply driver.Rule is arranged at intervals with the led light source that connects power supply driver on the pcb board 4, and top board 5 is provided with rectangular shaped rim 1, installs on the rectangular shaped rim 1 and is provided with diffuser plate 3.Pcb board 4, rectangular shaped rim 1, and diffuser plate 3 between constitute light-source chamber.
Power supply driver comprises power pack 7 and connecting line 8, and power pack 7 is fixedly installed on the top board 5 by screw 6.Power pack 7 is provided with and connecting line 8 interface matched, and connecting line 8 is fixed by welding on the power pack 7, and power pack 7 is connected with led light source by connecting line 8.The opposite side of power pack 7 also is provided with electric power connection line, and connecting line herein is externally to carry out power supply to connect.Power supply driver provides electric current for the led light source on the pcb board 4, and the driving LED light source carries out light output.
Pcb board 4 is provided with led light source, and led light source links to each other with power supply by connecting line 8.The pcb board 4 that is provided with led light source is fixed on the top board 5 by screw.
Further, in order to make pcb board 4 and top board 5 tightr contacts, between pcb board 4 and top board 5, use heat-conducting silicone grease.
, illumination even for the light that makes led light source improves, and the location arrangements of the led light source of a kind of LED panel light of the utility model has the consideration of following tripartite face:
(1), adopt which kind of led light source, different led light sources is different at the hot spot that diffuser plate 3 forms.Preferably, a kind of LED panel light that the utility model provides is selected the big led light source of lighting angle, and the lighting angle of led light source is 120 degree.
(2), the spacing of led light source and led light source size suitably.
Spacing between the adjacent led light source can not be too small, is that the led light source lamp that distributes on the unit pcb board 4 is too much because the spacing between the led light source is brought problem for a short time, thereby causes the whole lamp power of LED panel light excessive.The whole lamp power of LED panel light is excessive will inevitably to bring a series of problems such as heat radiation, therefore, will select suitable spacing when arranging led light source on pcb board 4.
On the other hand, the spacing between the adjacent led light source can not be excessive, and spacing is crossed conference and caused LED panel light illumination deficiency.
