[specific embodiment]

Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:

As shown in the figure, a kind of Novel LED light, include lamp holder 1, lampshade 2 and rectifier 8, rectifier 8 is installed in the lamp holder 1, circuit board 3 with a plurality of LED lamp pearls 31 is installed on the lamp holder 1, circuit board 3 links to each other by the stem line with rectifier 8, and lampshade 2 is sleeved on outside the foregoing circuit plate 3 and with lamp holder 1 and is fixedly linked.Wherein, be provided with heat dissipation channel 5 in the lamp holder 1, also be provided with the opening 18 that is used for the heat transmission that above-mentioned heat dissipation channel 5 is communicated with outside air on the lamp holder 1, leave the gap 4 of heat transmission between circuit board 3 circumference and lampshade 2 inwalls, gap 4 is communicated with heat dissipation channel 5, the gap 4 of Lian Tonging, heat dissipation channel 5 and opening 18 have formed the path of the hot-air diffusion of being convenient to the LED circumferential edge like this, have reduced LED and have generated heat to the influence in its service life, have prolonged LED service life.
