Large-power LED (light emitting diode) integrated light distribution and radiating device

Abstract

The invention discloses a large-power LED (light emitting diode) integrated light distribution and radiating device, and the device provided by the invention can be used for simultaneously realizing heat dissipation and lighting effect scattering. In a light distribution device, a smaller sealing cavity space is formed by a toughened glass cover, a fixed ring, a small O-ring seal, a light distribution plate, a lining plate and a large O-ring seal, thus the service efficiency of a light source is utilized effectively, and the scattering of light is effectively weakened; in a radiating device, the heat conducting parts of radiating fins are provided with fastening holes and pouring holes, and a plastic heat conducting material can be injected; the quantity and specification of the radiating fins are determined by the heat dissipation requirement of a heat source body and the working environment, the fastening holes are used for assembling the radiating fins into a radiator, the fastening holes are in close fit with the heat conducting plate and the radiating fins through heat conducting bolts, and the heat source is uniformly conducted to the radiating fins; and the light distribution device is connected with the heat conducting plate through a screw.

Description

technical field [0001] The invention relates to the field of LED lighting sources, in particular to a high-power LED integrated light distribution and heat dissipation device applied to municipal street lamps, outdoor environmental protection and energy-saving lighting, projecting lamps and indoor lighting lamps. Background technique [0002] At present, there are mainly two types of LED light sources: multiple low-power LED combined street lights and high-power integrated packaged LED street lights. Multiple low-power LED combined street lights are easy to solve heat dissipation, and the lumen value of a single chip package is high, but the visual effect is poor. Stars, overlapping shadows on the road surface, may easily cause visual fatigue or dizziness to the driver, and the circuit system of the lamp is complicated, the circuit port of the lamp is more, the reliability is reduced, the circuit is difficult to realize dimming, easy to be damaged, and the power conversion ra...
