Description

technical field [0001] The invention relates to a multi-faceted high-power LED light bulb. Background technique [0002] Traditional light bulbs are generally incandescent light bulbs, which have low illuminance, dim light, and are not energy-saving; after incandescent light bulbs, fluorescent light bulbs (also known as energy-saving lamps) appeared. Powder, so not environmentally friendly. At present, there are more energy-saving and environmentally friendly LED light sources, and LED light bulbs are produced thereupon. LED has many advantages such as high luminous efficiency, energy saving and long life, and its application is becoming more and more extensive, representing the development direction of future lighting sources. Due to the inherent structure of the LED itself, the luminous angle of the LED light source is limited to a certain extent. For the sake of illumination, LED bulbs cannot emit light in all directions of the lamp body like traditional incandescent la...

AI Technical Summary

Problems solved by technology

Due to factors such as the size and shape of the bulb, the existing LED bulbs cannot provide a larger heat dissipation area, which also results in the inability of the existing LED bulbs to install more LEDs to meet the requirements of multi-faceted lighting.

[0004] In order to provide good heat dissipation for existing LED light bulbs, all or part of the lamp housing is generally made of metal such as aluminum, and the light source board integrated with LED chips is connected to the metal lamp housing to improve the heat conduction effect. While improving the effect of heat conduction and heat dissipation, there is a potential danger of short circuit leakage between the metal lamp housing and the drive circuit, which poses a safety hazard, especially in high-voltage lamps, which cannot meet the requirements of relevant safety regulations
