LED lighting seems on track, However, currently there are still many unresolved issues. Hard decent, universal consumer, the price is often a key consideration, however, the cost of LED lighting is still high, in addition to the yield of the LED itself, too complex, constructi on is also a induction lighting lighting is the main cause of the high cost. Replace incandescent light bulbs LED lighting products, you need to have the substrate LEDs, ACDC conversion, the regulator IC and a large area of ??heat sink, especially a large area of ??the heat sink has long been the bottleneck of LED lighting can not be avoided, although the LED less luminous emanating infrared temperature rise compared to incandescent and fluorescent slow, then LED operation that will produce temperature, and because the package features, easy distribution, need to shed the high temperature through a passive heat sink, LED temperature is maintained at the allowable value, to take in order to reduce the LED heat exhaustion and extended product life, while still aluminum products as the main material, the larger the area, but also make the rising costs.

Different thermal design

Also have considerable relevance for the thermal module design and bulb quality, and good thermal design, the light emitted by the product to be stable and long life; module for interior lighting is so, let alone on the outdoor harsh environments street lights and street lighting modules, especially in the desert or the equator, the temperature of rapid change, it is a major challenge for LED lighting. Long-term development of the traditional lighting products have been already quite mature, and less than the LED lighting variables, has long been in the complex environment in normal operation, LED lighting due to the beginning of development, the manufacturers of components integrated features also can not be completely master, although with the LED lighting products, but the final product design has been poles apart, just there are several different interpretations of the thermal module.

In addition, led lights for homes  hardware is still in the design of the transition period, current products, especially home, to take a more alternative products, LED lighting is to make to adapt to the existing home lighting architecture, rather than to change the existing structure to adapt to the LED lighting. The main reason lies in the existing lighting structure for many years, in order to meet the not yet fully mature LED lighting, but also failed to fully replace the current equipment. In particular to the replacement of fluorescent lights is the most trouble, in particular, the majority of consumers have become accustomed to with the relay, LED lighting, however, do not need high voltage to start the feature, but will cause damage to the product, knowing that to persuade consumers to unload The relay can be natural products, they still need to install one to avoid the relay instantaneous pressure buffer device to avoid in case, but also the costs.
