Embodiment Construction

[0022] See the structure diagram Figure 1 to Figure 6 , A miniature light source "light emitting diode (LED) soft flat panel display (illumination) device". Including light source (LED or patch and current limiting protection resistor) 3, light guide plate 2, frame 1, lighting material layer 4, transparent protective plate 5, graphic carrier 6, sealing strip 7, protective plate liftable mechanism 8, printed circuit board 9. The frame 10 (such as the solid light guide plate does not need to use 10) and other components.

[0023] In one example, the surface of the light guide plate is coated (or silk-screened, sprayed, etc.) with lighting materials. After the light-emitting diodes are energized and emit light, the light passes through the light guide plate and the interface through complex optical principles such as light reflection, refraction, and diffraction, and forms on the surface of the lighting material. Soft surface light source.

[0024] In one example, the surface of the ...

Abstract

A subdual flat display device of luminous diode consists of frame, light guide plate, luminuos diode at end edge of light guide plate, transparent protective plate, picture carrier, protective printed circuit board, sealing strips, lifting mechanism and current-limiting resistance.

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...
