Background technology
The LED illumination promptly is a led lighting, is a kind of semiconductor solid luminescence device.It is to utilize the solid semiconductor chip as luminescent material, in semiconductor, through carrier compound energy of emitting surplus takes place and causes photo emissions, directly sends red, yellow, blue, green, blue or green, orange, purple, white light.The LED illuminating product utilizes LED as the produced ligthing paraphernalia of light source exactly.
Pendent lamp generally must be fixed with chain sling, suspension hook hanging, and the upper end is connected with the built-in fitting of building, and pendent lamp light requires can not hinder people's normal line of sight, also can not hinder the sight line that the people hopes mutually, or make us feeling dazzling.It is appropriate that the canopy Material Selection is wanted, and just can generation not make us uncomfortable dazzle.When the lampshade moulding was complicated, in the environment of moist, many dirt, light fixture got rusty easily, falls lacquer, and lampshade covers dirt light can be day by day dim, did not often maintain, cleaned, and illumination one annual reduces approximately 30 percent according to statistics, does not go out several years, and pendent lamp is with dim nothings brilliance.
The power tube of the LED power supply of the photodetachment heat dissipation LED pendent lamp of existing band groove generally is set directly on the wiring board, causes heat comparatively concentrated like this, is unfavorable for heat radiation; In order to address this problem, the technical staff adopts the set-up mode perpendicular to wiring board, but has increased the stress of pin like this, and long-term the use is prone to cause potential safety hazard.
The power supply lid structure setting of the photodetachment heat dissipation LED pendent lamp of existing band groove is comparatively unreasonable, is unfavorable for heat radiation, also possibly cause foreign material to fall in the power supply, thereby cause the generation of problems such as power supply short circuit.
Summary of the invention
The present invention provides a kind of photodetachment heat dissipation LED pendent lamp with groove, and the power pipe heat dispersion that has mainly solved existing pendent lamp is poor, pin stress is big; The problem of prior art unreasonable structure.
Technical solution of the present invention is following:
The photodetachment heat dissipation LED pendent lamp of this band groove comprises led light source, LED power supply, pendent lamp housing and canopy, and said canopy is arranged at the led light source outside and is connected with pendent lamp housing light source side, and said pendent lamp housing dorsal part is provided with heat abstractor; Said led light source is two, and two led light sources are symmetricly set in pendent lamp housing light source side; Said LED power supply is arranged in the heat abstractor of pendent lamp housing dorsal part; In the centre at the back side, two led light source positions and do not overlap with led light source; Said pendent lamp housing dorsal part is provided with heat abstractor, and said heat abstractor is made up of equally distributed fin, comprises subzero temperature radiating part and streamline radiating part; Described subzero temperature radiating part is arranged on the subzero temperature radiated rib group on the pendent lamp housing short transverse; The streamline radiating part is arranged on the streamline radiated rib group on the pendent lamp housing width, and said pendent lamp housing dorsal part is provided with heat abstractor, and the centre of heat abstractor is provided with groove; The width of groove is 1/3 ~ 1/4 of a fin width, and the degree of depth of groove is 1/2 ~ 9/10 of a fin maximum height; Said LED power supply comprises wiring board, power supply box body and power supply lid; Said wiring board is fixedly set in the power supply box body; The power supply box body is " U " type or " L " type, comprises power pack body sidewall and power supply box plate, and wiring board is fixedly set on the power supply box plate; Power tube is electrically connected with wiring board, and power tube is fixedly set on the power pack body sidewall; The power supply lid is the U type, comprises that the power pack caping covers and be symmetricly set in the limit lid at top cover two ends, and top cover and limit cover a plurality of bar holes that are useful on heat radiation all are set, and the limit covers and also is provided with the slotting formula slotted eye that is used for extracting power supply cord; The width of bar hole is less than 3mm; The bar hole gross area account for power pack caping capping long-pending more than 60%.
The invention has the advantages that:
The power supply of the photodetachment heat dissipation LED pendent lamp of band groove provided by the invention adopts power tube is arranged on the power pack body sidewall; And then pin is connected with wiring board; Because the power pack body sidewall is that heat sink material is processed; And power tube is completely fixed and be fitted on the power pack body sidewall, has promptly solved heat dissipation problem, has solved the stress problem of pin again; Simultaneously, power supply lid dutycycle is provided with rationally, and intensity is high, is beneficial to processing, and cost is low.
