Summary of the invention
The present invention provides a kind of rotary photodetachment LED floodlight with groove, and the power tube heat dispersion that has mainly solved existing LED floodlight power supply is poor, pin stress is big; The existing power supply wiring board is provided with unreasonable, the problem of installation and maintenance inconvenience.
Concrete technical solution of the present invention is following:
A kind of rotary photodetachment LED floodlight with groove comprises led light source, LED power supply, floodlight housing and floodlight lampshade, and said floodlight lampshade is arranged at the led light source outside and is connected with floodlight housing light source side; The floodlight dorsal part is provided with fixed connection apparatus; Said fixed connection apparatus comprises firm banking and installing rack, and firm banking is fixedly connected with the floodlight dorsal part, and is provided with the rotation draw-in groove; Installing rack one end is connected with firm banking through the tightening device; The other end is connected with mounting points, and the tightening device moves in draw-in groove, and said floodlight housing dorsal part is provided with heat abstractor; Said led light source is two, and two led light sources are symmetricly set in floodlight housing light source side; Said LED power supply is arranged in the heat abstractor of floodlight housing dorsal part; In the centre at the back side, two led light source positions and do not overlap with led light source; The centre of said 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; Comprise wiring board, power supply box body and power supply lid, said wiring board is fixedly set in the power supply box body, and said power supply box body is " U " type or " L " type; Comprise power pack body sidewall and power supply box plate, wiring board is fixedly set on the power supply box plate; Said power tube is electrically connected with wiring board, and power tube is fixedly set in the power pack body sidewall; Be provided with gap between said wiring board and the power supply box plate less than 5mm.
Be provided with at least three pad posts between above-mentioned wiring board and the power supply box plate, the length of pad post equates with the gap less than 5mm.
Above-mentioned wiring board is fixedly set on the power supply box plate through screw, and screw passes the power supply box plate successively and is fixedly connected with wiring board with the pad post again, and the pad post is provided with and the suitable internal thread of screw external screw thread.
The pad post of above-mentioned power supply is 4, and each fills up post and is symmetrical set, and the distance between wiring board and the power supply box plate is 3mm, and the length of pad post is 3mm.
The invention has the advantages that:
1, the power supply of the rotary photodetachment LED floodlight of this band groove 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.
2, in the power supply of the rotary photodetachment LED floodlight of this band groove, be provided with the space between wiring board and the power supply box plate, the air channel at first can be regarded in this space, is beneficial to the formation air-flow, and secondly, installation and maintenance is comparatively convenient.
