Detailed description of the invention
Below in conjunction with the accompanying drawing in embodiment of the present invention, the technical scheme in embodiment of the present invention is clearly and completely described.
Please also refer to Fig. 1 and Fig. 2, it is a kind of light fixture 100 provided by the invention.Described light fixture 100 comprises lamp holder 10, lens subassembly 30 and light source assembly 50, and lens subassembly 30 is fixedly connected with light source assembly 50 and is installed in lamp holder 10.
Lamp holder 10 comprises back cover 12, protecgulum 14, support 16 and cable and introduces assembly 18.Protecgulum 14 is installed on back cover 12, lens subassembly 30 and light source assembly 50 to be packaged in back cover 12.Support 16 is installed on back cover 12, for lamp holder 10 is installed on installing rack (not shown).Cable introduces assembly 18 for cable is introduced lamp holder 10, power to light source assembly 50, thus illumination.
As a further improvement on the present invention, back cover 12 comprises multiple rib 120.Described rib 120 is arranged at the diapire of back cover 10, for distributing the heat that light source assembly 50 produces.
Please also refer to Fig. 3 and Fig. 4, lens subassembly 30 comprises multiple lens 32 and location division 34, and described lens 32 are installed in location division 34.Location division 34 comprises location-plate 340 and multiple locating dowel 342.Location-plate 340 is provided with multiple and described lens 32 accepting hole (being blocked by lens 32) one to one, and described lens 32 are installed in described accepting hole.Each locating dowel 342 is protruded from the bottom of location-plate 340, for being fixedly connected with lens subassembly 30 and light source assembly 50.
In the present embodiment, each locating dowel 342 is stud.
Please also refer to Fig. 5 and Fig. 6, light source assembly 50 comprises multiple and described lens 32 light source 52 and substrate 54 one to one, and described light source 52 is fixed on substrate 54.Lens 32 described in each cover light source 52 described in each.
In the present embodiment, substrate 54 is aluminium base.Lens 32 are fully-reflected type lens.Light source 52 is lambert's type light emitting diode.
