Abstract:
An LED lighting device is provided, having a lamp housing and at least one LED module. The lamp housing has a lamp cover and a housing-type heat-dissipating lamp bracket that directly radiates the heat generated by the LED module. The housing-type heat-dissipating lamp bracket is entirely made of heat-dissipating material, and several radiating hole devices are set on the housing-type heat-dissipating lamp bracket. The radiating hole devices on the housing-type heat-dissipating lamp bracket and the gaps between the LED modules form a mutually-reinforcing thermal honeycomb effect, providing a heat dissipation channel with unhindered air convection. Radiating holes are set at the head and tail of the housing-type heat-dissipating lamp bracket. The radiating holes and the gaps between the modules enhance the heat-dissipating effect and enhance air convection, to improve heat dissipation from the lamp housing and provide improved heat dissipation effect for the entire lamp.
