A multi-light source bulb lamp

Abstract

The invention relates to a multi-light-source bulb lamp. The multi-light-source bulb lamp uses a unique design of a heat dissipation board and multiple sets of light sources, the multiple sets of light sources are arranged according to the structure of the heat dissipation board, the light radiation range of light of the multiple sets of light sources is made not to be overlapped as much as possible, and therefore the multi-light-source bulb lamp has a wide-angel light radiation range. The light radiation range is large than 300 degrees, a three-dimensional high-light effect large than 300 degrees can be generated, after three sets of LED bulbs are powered on to work, heat is radiated into air through corresponding aluminum substrates, an upper heat dissipation piece connected with the aluminum substrates and a metal lamp holder, and therefore the multi-light-source bulb lamp has good heat dissipation performance. The three sets of light sources share one heat dissipation piece for heat dissipation, so the multi-light-source bulb lamp saves space, and is wide in light radiation range, good in heat dissipation performance and long in service life.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a bulb lamp with multiple light sources. Background technique [0002] As a new type of light source, light-emitting diode (LED) has the characteristics of energy saving, environmental protection, long life and small size, and is being widely used in various aspects of the lighting field. LED is a solid-state semiconductor device that can convert electrical energy into visible light. Its basic structure generally includes a bracket with leads, a semiconductor wafer placed on the bracket, and a packaging material (such as fluorescent silicone or epoxy resin) that seals the wafer around. ). The above-mentioned semiconductor wafer contains a P-N structure. When the current passes, electrons are pushed to the P region, where the electrons and holes recombine, and then emit energy in the form of photons, and the wavelength of light is determined by the material forming the P-N structure. .

Problems solved by technology

During the working process of the bulb lamp using LED, only a part of the electric energy is converted into light energy, and the rest is converted into heat energy, which leads to an increase in the temperature inside the bulb lamp, which is the main reason for its performance degradation and failure; ordinary The bulb lamp has only one group of LED lights for upward lighting or middle lighting. The lighting structure is single, the lighting effect is not good, and the coverage angle is small. This disadvantage affects the overall lighting effect of the bulb lamp.
