Description

Diffuse light guide lighting fixtures

technical field

The utility model relates to a diffused light-guiding lighting fixture, in particular to a lighting fixture that evenly illuminates and projects the light emitted by a light-emitting diode by means of guiding light.

Background technique

Most of the early light source projection lamps used light bulbs as the light source. In recent years, because the manufacturing technology of light-emitting diodes has become increasingly mature, not only can there be a variety of colors to choose from, but also has practical advantages such as environmental protection, power saving, and long life, and has gradually replaced traditional lamps. However, the light of LEDs is quite concentrated and the irradiation range is small. Direct use is likely to cause uncomfortable glare to users. Therefore, it cannot be used when the light bulb is used for reading or the light bulb must be exposed for direct lighting. For clear light bulbs, it is necessary to eliminate the glare emitted by the bulbs, and the surface of the bulbs must be frosted, so that the manufacturing process of the bulbs will be more complicated, and the brightness will be greatly reduced, resulting in a waste of energy.

Therefore, how to solve the above-mentioned existing problems and shortcomings is a topic that is urgently desired to be researched and developed by the related industry.
