1. High luminous efficiency
Luminous efficacy of the incandescent lamp is 7～14lm/W, that of fluorescent lamp is 50～80lm/W, that of HV sodium lamp is 80～12lm/W, most of the power consumption turns into thermal loss. Luminous efficacy of the LED reaches 90～120lm/W, with good monochromaticity, narrow light spectrum, optional color temperature and good color rendering property.
2. Less power consumption
    Power of single LED is 1～3W, adopts DC driving, single-tube driving voltage is 3～35V, current is 0.35～1A, with quick reaction speed and high-frequency operation. Under the conditions of same luminous effect, its power consumption is one eighth of that of incandescent bulb, and a half of that of fluorescent tube.
3. Long service life
    The general light sources work to shine by using electronic light radiation filament, so it is easy to burn and have thermal deposition and light attenuation. While, LED light source is featured with small volume, light weight and epoxy resin encapsulation, can withstand high-strength mechanical shock or vibration, theoretical service life as long as 100,000 hours, greatly reducing the maintenance costs.
4. Safe and reliable
    Cold light source, no thermal radiation, the light type and angle can be controlled accurately, with soft light, free from glare, no mercury or sodium or other hazard materials. The built-in microprocessing system controls the luminous intensity and regulates the luminous way.
5. Environmental friendly
    LED is a solid illuminant, is shock resistant, impact resistant, unbreakable. The waste can be recycled, no pollution to the environment.
6. Low use cost
    LED light source is a bit more expensive than traditional light sources, but you can recoup the investment of LED light source by saving the energy in one year. As it is a maintenance-free light source, you can save the maintenance cost in the following years, greatly cut down the use cost.

LED光源特性 Features of LED light source
1. 发光效率高
白炽灯光效为7～14lm/W，荧光灯50～80lm/W，高压钠灯80～12lm/W，大部分的耗电变成热量损耗。LED光效可到达90～120lm/W，而且其光的单色性好、光谱窄，色温可选定，显色性好。
2. 耗电量少
LED单颗功率1～3W，采用直流驱动，单管驱动电压3～35V，电流0.35～1A，反应速度快，可高频操作。同样照明效果的情况下，耗电量是白炽灯泡的八分之一，荧光灯管的二分之一。
3. 使用寿命长
普通光源采用电子光场辐射发光，灯丝发光易烧、热沉积、光衰减等缺点。而采用LED光源体积小、重量轻，环氧树脂封装，可承受高强度机械冲击和震动，不易破碎。理论寿命达10万小时，可以大大降低灯具的维护费用，避免频繁换灯。
4. 安全可靠性强
冷光源，无热辐射，能精确控制光型及发光角度，光色柔和，无眩光；不含汞、钠元素等可能�：】档奈镏�。内置微处理系统可以控制发光强度，调整发光方式。
5. 有利于环保
LED为全固体发光体，耐震、耐冲击不易破碎，废弃物可回收，没有污染。
6. 使用成本低
LED光源比传统光源价格稍高，但是用一年时间的节能可收回光源的投资，LED属免维护光源，可节省以后几年的维修费用，大大降低了使用成本。
