【Detailed ways】

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

Embodiment 1, as shown in Figures 1 to 4, an LED track light includes a hollow shell 1, which is a hollow cylinder with openings at both ends, and a rear radiator 2 is arranged inside the shell 1, and the rear Radiator 2 dissipates heat through fins, housing 1 rear end surface is provided with the heat dissipation plate 6 that covers the rear end opening, heat dissipation plate 6 is provided with a plurality of rear heat dissipation holes 61 communicating with rear heat sink 2, the housing 1, the heat at the rear end can flow out from the rear cooling holes 61. The front end of the rear radiator 2 is provided with an LED lamp 3 and a reflective cup 4 that reflects the light of the LED lamp 3. The reflective cup 4 is conical, the small diameter end covers the LED lamp 3, and the large diameter end faces the rear radiator. 2 extends in the opposite direction. The reflective cup 4 is equipped with a front radiator 5, the front radiator 5 is a hollow cylinder, the reflective cup 4 is installed in the hollow of the front radiator 5, and one end of the front radiator 5 is arranged in the housing 1. The radiator 5 can be threadedly connected with the inner wall of the housing 1, and the front end of the reflector 4 is provided with an anti-glare ring 53 on the hollow inner wall of the front radiator 5, and a plurality of strips are provided on the front radiator 5 to connect the inside of the housing 1. The radiating groove 51 for heat export, the radiating groove 51 is evenly distributed on the outer circumference of the front radiator 5, and the radiating groove 51 extends toward the rear radiator 2.
