Problems solved by technology
[0002] Illuminated display boards, such as illuminated advertising boards or advertising light boxes, are indispensable advertising supplies for modern life and commerce, and their usage is also increasing. Generally, the light sources of commercial lighting advertising boards or advertising light boxes use tungsten filament bulbs and mercury fluorescent lamps, while Among them, the tungsten filament bulb converts most of the electric energy into radiant heat during the lighting process, so its luminous efficiency is not high, but the radiant heat generated is very high. Excessive temperature affects its service life
Therefore, it is gradually eliminated; and although the luminous efficiency of mercury fluorescent lamps is better than that of tungsten bulbs, it has the disadvantages of large power consumption and short service life, and the mercury coated on the inner wall of the lamp tube of mercury fluorescent lamps will cause damage when the lamp tubes are discarded. Environmental pollution, and the manufacture and assembly of lamp holders used with mercury fluorescent lamp tubes is relatively cumbersome

The invention illuminating display board is mainly composed of illuminating display board body and lighting fixture installed on inside the said body. The features of the invention are as follows: The said lighting fixture incldues an motherboard, multi-LED, two outlet sockets and a reflector piece. There are layers from motherboard up: a base layer, an inner insulating layer, a circuit layer and an outer insulating layer. Part circuit is exposed from the outer insulating layer for soldering the outlet LED and other electronic parts. There are special paper and the reflector piece on sticking layer located on bottom of the base layer. Reflector surface of the reflector piece reflects light to the farther place.
Description
technical field [0001] The present invention relates to a lighting display board using light emitting diodes as light sources, in particular to a lighting display board using multiple light emitting diode combined lamps as light sources, such as illuminated advertising boards or advertising light boxes for advertising. Background technique [0002] Illuminated display boards, such as illuminated advertising boards or advertising light boxes, are indispensable advertising supplies for modern life and commerce, and their usage is also increasing. Generally, the light sources of commercial lighting advertising boards or advertising light boxes use tungsten filament bulbs and mercury fluorescent lamps, while Among them, the tungsten filament bulb converts most of the electric energy into radiant heat during the lighting process, so its luminous efficiency is not high, but the radiant heat generated is very high. Excessive temperature will affect its service life. Therefore, it ...
