Abstract

The utility model discloses a projecting lamp with heat isolation function and radiating rib self-cleaning function, comprising a lamp body, a LED lamp board arranged in the lamp body, a LED lamp arranged on the LED lamp board, and a driving circuit connected with the LED lamp circuit board. Radiating ribs are arranged on the back end of the LED lamp board. The utility model is characterized in that the utility model comprises a driving box and at least two isolation pads. The driving circuit is arranged in the driving box. The driving box is arranged at the back end of the radiating ribs. Isolation pads are arranged between the driving circuit and the radiating ribs. Because the driving circuit and the radiating ribs are separated by the isolation pads, the working life of the projecting lamp is extended by reducing the heat-conduction area which prevents heat from conducting to the driving circuit. Moreover, dust accumulated in the radiating ribs is cleared by the natural wind and rain in the outdoor environment and discharges along the interspaces between the driving box lid and the radiating ribs; as a result, the dust covering the radiating ribs can be cleared automatically.
