Technical field

The invention relates to the field of lighting technology, and relates to an LED lamp, in particular to a multi-faceted lamp. Background technique

Conventional light bulbs are generally incandescent light bulbs, which have low brightness, are not bright, and are not energy efficient. Fluorescent bulbs appear after incandescent bulbs. Although they are more energy efficient and brighter, they are not environmentally friendly due to the large amount of phosphor used.

With the increasing innovation of electronic technology in recent years, the accelerated power-saving LED lamp has replaced the traditional tungsten light bulb, which is widely used in various electronic products. LED lamps have high luminous efficiency, long energy saving and long life. And many other advantages, its application is more and more extensive, representing the development direction of future lighting sources. Due to the inherent structure of the LED itself, it is determined that the illumination angle of the LED light source is limited.
