Description

Technical field

[0001] The invention transforms the light emitting diode (LED) point light source into a soft surface light source, thereby realizing a soft light flat panel display (illumination), and belongs to the field of optoelectronics and new materials. Background technique

[0002] Various outdoor billboards and urban (including residential) lighting projects are basically dominated by neon lights, incandescent lights and fluorescent light boxes.

[0003] The advantages of neon lights are high brightness, but the outstanding disadvantages are high voltage, large power consumption, short life, complicated installation, and high maintenance costs.

[0004] The advantages of incandescent lamps and fluorescent lamps are also high brightness, but the prominent disadvantages are also high power consumption, short life span and random burnout.

[0005] Even energy-saving lamps have the disadvantages of high power consumption and random damage. The above-mentioned types are diffi...
