The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Extremely shown in Figure 6 like Fig. 1; The described a kind of LED light fixture of the utility model comprises lampshade 1, is fixed at the mounting disc 2 of lampshade 1 cover mouth; Be provided with power supply 4 in the said lampshade 1; Said mounting disc 2 is fixed with some light source modules 3 on lateral surface, promptly described lampshade 1, mounting disc 2 and light source module 3 have the utility model of formation main element.
Said lampshade 1 top is provided with fixed hole position 5, is used to install and fix the utility model.
Said mounting disc 2 forms some Connection Blocks 21 on lateral surface, said Connection Block 21 is provided with fixing hole 22.Said mounting disc 2 is made by metal material, is evenly distributed with some louvres 23 on it in addition, with further raising radiating effect.
Said light source module 3 comprises lens cover 35, and light shell outer cover 31 is located at the circuit board 33 between lens cover 35 and the light shell outer cover 31.Said circuit board 33 is provided with locating hole, and locating hole connects circuit board 33 both sides, is provided with heat conduction screw rod 32 in the said locating hole.Said heat conduction screw rod 32 1 end end faces are provided with LED34; Also being circuit board 33 is provided with some LED near a side of lens cover 35; The through hole that said heat conduction screw rod 32 other ends pass on the light shell outer cover 31 is fixedly connected with mounting disc 2; Particularly, the other end of said heat conduction screw rod 32 is threaded with fixing hole 22.
