Detailed description of the invention
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing 1 and by detailed description of the invention.
A kind of shot-light with spherical diffusion cover, comprise reflector 1 and lamp holder radiator 2, on the end face of described lamp holder radiator 2, be wholely set heating column 3, the root of described heating column 3 is upwards provided with inclined-plane 7, the top of described heating column 3 is provided with heat-conducting substrate 4, the bottom surface of described heat-conducting substrate 4 is evenly equipped with the first LED light source 5 around the circumferencial direction of described heating column 3, the end face of described heat-conducting substrate 4 is evenly equipped with the second LED light source 8, one end of described heating column 3 is arranged with spherical diffusion cover 10, described the first LED light source 5 and the second LED light source 8 wrap to be respectively located in described spherical diffusion cover 10, the axle center place of the bottom surface of described reflector 1 is provided with the first circular hole, described the first circular hole match with described heating column 3 and bottom surface and the described inclined-plane 7 of described reflector 1 fastening.First light source at heating column top and secondary light source spherical diffusion cover are covered in spherical diffusion cover, in protection light source, make whole lamp luminous more even, can not produce dazzle.
The bottom surface of described lamp holder radiator 2 is provided with insulating barrier 6, the upper surface of described insulating barrier 6 is upwards concaved with the first shrinkage pool and the second shrinkage pool, described the first shrinkage pool and the second shrinkage pool respectively with the first circular hole and the second circular hole close-fitting that are arranged on the bottom surface of described lamp holder radiator 2.This structural design, effectively isolates lamp holder radiator 2 bottom surfaces and lamp socket, thereby effectively stops lamp holder radiator 2 charged.
