Using LED lighting, while more and more, we have to ask, as a rising industry soon, why almost all of the commercial lighting will have no doubts about it, LED lighting has what charm it with LED lights ?
1, LED energy saving First, LED consumes less energy, which means consuming less resources, which means less power consumption and corresponding energy consumption in the transportation of the way, thereby also reducing the energy efficiency of the power generation process depletion and environmental pollution due to power generation. Secondly, with respect to the terms of conventional light sources, LED contains less harmful substances. Most conventional light sources containing a large amount of gaseous harmful substances, when light damage be dangerous, when processing will produce harm. LED contains only a small amount of solid substance that avoids harm to us when damaged, the recovery time is also very convenient separation process.
2, LED lifetime LED lighting can reach 50000h good life, the failure rate is very low. In the actual operation of commercial space, and it means that if seven days a week, 12 hours a day, led lamps can serve for 11 years, which is the traditional light sources can not be achieved. Of course, lower bad light caused by lighting effects are inevitable but also far lower than traditional lights, which need to be considered early in the lighting design. For LED lamps, the effective heat dissipation is very important, because the accumulated heat will cause severe attenuation of the luminous efficiency. Therefore, in actual use, be sure to use a good quality thermal design lamps.
3, LED highly efficient? Basically, it is characterized by small particles by a small current, it can issue a large number of directional light. led beam angle is usually 15 ° to 180 °, which can precisely control the light, so that the light fixture in the cavity loss is minimized. This is significantly different from the place of traditional light sources, traditional light-emitting angle is generally very wide, a lot of light in the escape do not need directions. This means that when using the LED light source, less light can achieve the same level of illumination, reducing energy consumption.
On the other hand, LED luminous itself stronger, that is, higher luminous efficiency. Incandescent electro-optical conversion rate is about 5%, fluorescent 30%, LED40%. Another measure is the value of the luminous efficiency of the light source, the light source 1 is converted into the light flux watt power efficiency of the unit is lm / W. Mid-1990s, the first one white LED luminous efficiency of about 0.1lm / W, now commercially cool temperature white LED, the luminous efficiency has reached 160lm / W, laboratory data has more than 250lm / W, LED illustrate the potential is huge.
4, LED cost-effective LED so expensive, why is it said that the high cost-effectiveness of it? Yes, LED expensive, but for the cost-effective, this is just one of the considerations. [Similarly, for now LED products are not expensive, you have to understand, this is just one factor to consider!] If we consider the overall cost-effectiveness, then, from the whole life cycle, that is to have the whole life cycle the concept of cost, not just consider the initial cost. As previously mentioned, LED more energy efficient than traditional light sources, it is estimated that if all light sources are replaced with LED, you can save 30% of energy, and lighting accounts for almost 20% of human energy consumption. For older and more power-hungry incandescent light source such as through simple replacement of LED bulbs, it can achieve 70% energy savings. LED longer life, so replacement costs and lower maintenance costs during the whole life.
LED infrared radiation is almost negligible compared to traditional light sources produce less heat, so the lower the energy consumption of air conditioning systems. LED can be more flexible control by the control system, including switching and dimming by people and daylight sensors, greatly expanding the potential for energy savings. Finally, LED safer and more conducive to recovery, unlike many traditional light sources, because it contains hazardous substances such as mercury, require special equipment and complex process during recovery.
