Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.

As shown in Figs 1-4, the radiator of a kind of LED provided by the utility model, including tubular shell 10, wherein one End is provided with LED illuminating source 11, and the other end connects light source output route 12, and nearly illuminating source end 11 is provided with a radiator 13, the radiator 13 and tubular shell 10 are integrally formed, and the radiator 13 includes bottom case 131, and the bottom case 131 has one Groove 1311 holds the outlet line 12 of LED illuminating source 11 to being placed in one, and the outlet line 12 is worn from radiator 13 It crosses, the two sides perpendicular separation of the bottom case 131 extends several cooling fins 132 being parallel to each other, the another two sides of the bottom case 131 Face extends two heat-conducting plates 133, and the cooling fin 132 and the heat-conducting plate 133 form an accommodating cavity 1341, and a fan 134 holds In in accommodating cavity 1341, the cooling fin 132 is provided with a positioning protrusion 135, and such fan 134 is dissolved in accommodating cavity 1341 When middle, fan 134 is stuck in the position for leaving 131 certain distance of bottom case by positioning protrusion 135, can more preferably play fan 134 in this way Fan heat function, the radiator 13 further includes a fan cover 136, and the fan cover 136 has multiple U-shaped ventilation holes 1361,

Gap between the adjacent cooling fin 132 of radiator 13 as above forms perforative air duct, and fan 134 blows to LED hair The outlet line 12 of radiant 11, the air duct that the rear gap by between cooling fin 132 is formed return, after by fan cover 136 Ventilation hole 1361 blowout and ambient air formed convection current, the device is by will form perforative wind between abutting fins 132 The wind direction of the ventilation hole 1361 of road and fan 136 is consistent with air duct, improves radiating efficiency.

Further, the heat-conducting plate 135 is extended through the another two sides of bottom case 131 and bottom case 131 is to be integrally formed, Extend with cooling fin 132 with bottom case 131.This design not only maximizes the contact area of heat-conducting plate 133 and cooling fin 132, has Effect improves heat conduction efficiency.

Further, fan cover 136 has multiple U-shaped ventilation holes 1361, keeps the hot gas blown out through passing through fan 136 fast The discharge shell 10 of speed accelerates heat dissipation.

Further, LED light source component 14 is also equipped on shell 10, the LED light source component 14 includes LED illuminator 141, the fixed shell 142 of lens, lens 143 and irradiation end cap 144, the lens fix screw thread of the shell 142 by one end It is fixedly connected with shell 10, the screw thread of the other end and the irradiation end cap 144 are screwed connection.

Further, the outlet line 12 is placed in the groove 1311 of bottom case 131, and fan can directly blow to the output Route 12 is then together shed its heat by the heat dissipation wind channel that heat-conducting plate 133 and cooling fin 132 are formed as early as possible, will not Keep the temperature of outlet line 12 excessively high, to protect outlet line 12.

The radiating principle of the utility model are as follows: in the actual operation process, the heat and defeated that LED light source component 14 generates The heat of route 12 is exported via heat-conducting plate 133 out, while the heat of outlet line 12 is dispelled by fan 134 and passes through heat-conducting plate 133 are transmitted to cooling fin 132, then dispel through fan 134 into air.
