Heat-dissipating led lamp with multiple light-emitting surfaces

Abstract

The invention discloses a heat-dissipation-type LED (light-emitting diode) lamp with multiple light-emitting surfaces. The heat-dissipation-type LED lamp comprises a heat sink, an aluminium base plate, a lampshade and a lamp bead arranged on the aluminium base plate, wherein the heat sink is a polygonal column body, and the aluminium base plate is correspondingly arranged on each side of the heat sink; and the lampshade is an olivary convolution body, the upper and lower ends of the lampshade are provided with locating holes which are matched and fixed together with the heat sink by virtue of fasteners, and the heat sink is internally provided with an outer through heat dissipation channel. The LED lamp provided by the invention has the advantages of wide irradiating surface, good heat dissipation effect, long service life and the like.

Description

technical field [0001] The invention relates to an LED lamp, more specifically, to a heat dissipation LED lamp with multiple light emitting surfaces. Background technique [0002] LED lamps use the luminous properties of semiconductors to emit light after they are energized. They have the advantages of energy saving, low power consumption, and long service life. Therefore, they have become the development direction of replacing traditional lighting sources and becoming emerging light sources. The current LED lamp technology is not yet mature. For example, a bubble-shaped LED lamp is composed of a lamp cap with a radiator, an aluminum-based circuit board, a lamp bead and a lamp cover. The heat of the aluminum-based circuit board is dissipated through the radiator of the lamp cap. Limited by aluminum-based circuit boards and heat generation bottlenecks, it cannot solve the heat dissipation problem well, because poor heat dissipation will cause the lamps to age easily, thereby ...

AI Technical Summary

Problems solved by technology

Limited by aluminum-based circuit boards and heat generation bottlenecks, it cannot solve the heat dissipation problem well, because poor heat dissipation will cause the lamps to age easily, thus shortening the service life of the lamps and other issues

Moreover, LED lights are usually only set up as a single aluminum-based circuit board to achieve one-way illumination and have the disadvantage of a small illuminated surface.

Not very suitable for street lights or outdoor high-altitude lighting that require irradiated surfaces, high power, and long working hours

At present, although there are LED lights with multi-faceted illumination, the heat generated by them increases several times, but it cannot solve the problem of heat dissipation in long-term lighting work.
