LED as a new light source, is increasingly being integrated into people's daily lives, it is inseparable from the development of the demand for lighting. Compared to traditional light sources (such as fluorescent and incandescent), LED at close to the theoretical conversion efficiency than conventional light source efficiency 5-20 times higher. Even at this stage of mass production light effects, its level is between 2-15 times, combined with the advantages of its directivity, this gap will be even greater. Since the light-emitting principle of change led screen repair, their life will be much higher than traditional light sources. Mainly used to display advertising fonts (acrylic, plastic) night effects and identified it as a medium of text or logo, top or wall mounted on buildings led, both during the day effects the performance of identity, but also use LED as a light Shenzhen led light display at night showed another effect, which together with LED lighting applications, control systems led manufacturers of text or logo dynamic video control, and in some places thicker atmosphere entertainment, LED light source module has become corporate self-image display of the most important choices. led lights wholesale | Gao Jin photovoltaic (certified) | led by Jinan Optoelectronics Technology Co., Ltd.
