High-power LED tunnel lamp with hollow heat dissipation channel

The utility model discloses a high-power LED tunnel lamp with a hollow heat dissipation channel, which comprises a luminophor formed by arranging a plurality of unit high-power LEDs, a drive circuit board, a lamp holder body, light distribution lamp cups and a heat dissipation device, wherein all the unit high-power LEDs electrically connected with the drive circuit board are respectively arrangedin the lamp cups of corresponding quantity and in front of the lamp holder body, and the drive circuit board and the heat dissipation device are arranged at the back of the lamp holder body. The LEDtunnel lamp is characterized in that the lamp holder body is provided with a hollow heat dissipation channel running through the left side and the right side of the lamp holder body and two sides of the luminophor at the front part of the lamp holder body are provided with preposed fins. The LED tunnel lamp has the beneficial effects: since the hollow heat dissipation channel running through the left side and the right side of the lamp holder body is arranged, tunnel air can run through the cavity of the lamp holder body; since the preposed fins are arranged at two sides of the luminophor at the front part of the lamp holder body and the heat dissipation device of the part usually faces down or low side, the dust can be prevented from falling on the heat dissipation device of the part, thus optimizing the heat dissipation performances and prolonging the service life of the high-power LED.
