太阳能路灯光衰竭的成因探讨
温度其实就是LED路灯光衰的关键问题，偏偏LED路灯就卡在这个环节。LED路灯由于发光功率大于家用灯具，因此厂商在散热基板鳍片、散热模块的设计上费尽苦心，组装完毕需在灯具散热模块外面，加烤漆保护以防气候侵蚀。不料这个外部保护的喷漆却把散热模块的热度又封了回去，造成散热不良导致LED磊晶光衰。
In fact, temperature is the key problem of LED street lamp's decay. The LED street lamp is stuck in this link. LED street lamps are more luminous than household lamps, so manufacturers in the heat dissipation substrate fins, heat dissipation module design painstaking, assembled in the lamp heat dissipation module outside, with paint to protect against climate erosion. Unexpectedly, this exterior protective spray paint sealed the heat of the cooling module back, resulting in poor heat dissipation leading to LED epitaxial light decay.
LED磊晶发光热能属于小范围的集中热能，在高功率路灯的应用时，电力输入功率也大，LED的接口温度相当的高，在路灯长时间持续工作下，散热模块如不能有效散热，就会影响LED使用寿命及发光表现，像目前的LED路灯严重光衰就是这些因素所造成。LED路灯是在户外使用，有环境气候的干扰因素，所以多半的厂商是将LED路灯散热器外壳以阳极处理保护，或是加喷烤漆，以避免酸碱物质的侵蚀。
LED epitaxial luminous thermal energy belongs to a small range of concentrated thermal energy, in the application of high-power street lamps, power input power is also large, LED interface temperature is quite high, in the long-term continuous work of the street lamp, if the heat dissipation module can not effectively dissipate heat, it will affect the service life and luminous performance of LED, like the current LED street lamp serious light decay. These are the factors. LED streetlights are used outdoors, with environmental and climatic disturbances, so most manufacturers will be LED streetlight radiator enclosure with anodic treatment protection, or spray paint to avoid acid and alkali erosion.
阳极处理的寿命不长，时日稍久还是会氧化变色，如果要拆下重工，不但耗时耗工也会增加维护成本;烤漆保护成本较低，保护的功效也好，但是一般烤漆没有散热功能，漆体本身会形成阻隔作用，等于是加大LED路灯散热器的热阻抗，不但没有帮助，反而因为把热能封锁在散热器内，让LED发光功率降低，最后就导致严重光衰。以上一直在LED灯具业界存在的严重困扰，几乎是目前公共工程LED路灯无法顺利通过采购单位验收的主因。
Anode treatment life is not long, a little longer or will oxidize discoloration, if you want to remove heavy work, not only time-consuming labor will increase maintenance costs; paint protection costs are lower, the protection effect is good, but the general paint does not heat dissipation function, lacquer itself will form a barrier effect, is equivalent to increasing the heat of LED street lamp radiator Impedance, not only does not help, but also because the thermal energy is locked in the radiator, so that the LED light-emitting power is reduced, eventually leading to serious optical decay. The above has been a serious problem in the LED lighting industry, almost is the main reason that public works LED street lamps can not pass the acceptance of procurement units.
