The global promotion of low-carbon life, so LED becomes a new generation of environmentally friendly light source. At present, China has named semiconductor LED lighting included in the medium-and long-term technology development plan, which has been initially formed wafer production, chip preparation, encapsulated integrated LED application industry chain. In addition, our national focus on the promotion of LED Panel Light industry. In mid-October, the nation’s first LED theme park settled in Guangdong Science Center, the “Guangdong, Hong Kong and Taiwan LED industry Design Forum held at the same time.
Imitate and simple-build substitution is the bane of the LED street lamp
At present, LED applications and R & D is just to have simple replacement from LED and traditional light source. Almost all LED manufacturers follow the traditional street lamp design ideas, the pursuit of tens of watts, more than 100 watts of power LED street lamp with HPS lamps shape, installed the same way or compatible LED the street light and installed almost all HPS light source suitable for the “snake-heads (Tablet snakeheads) lamps as the standard design and manufacturing, rather than as a starting point for research and development to the law of the street light.
Second is invalid illumination problems. Currently, the majority of the public space, such as corridors, foot ladder, parking, bathrooms, elevator, across the street. Generally rely on the pass with a long time lighting, where is sometimes empty, so the energy is consumed. Therefore the most energy efficient technology is not on the wattage of the lights, but how to make the lights become more intelligent, more humane. When nobody used, it can enter a “sleep” state, and some people emerged, it will slowly wake up.
In addition, there is the visibility problem. The zebra crossing effects and serious air pollution, rain foggy weather environment caused the lights not bright enough on the ground, therefore, to reduce energy consumption, and not influence the ultimate goal of the street light visibility, the most important main direction is to strive to improve lighting uniformity. Good illumination uniformity can be appropriately reduced the average brightness of the lighting, which can achieve the same recognition to identify objects of visual effects, while at the same time to achieve the purpose of energy saving.
