 Traditional lighting dimmers: including thyristor dimmer (-cut), electronic dimmer (-cut), and remote control dimmer (infrared or RF type), as well as some commercial lighting dimming system.


       Electronic dimmer must be constructio n to change the lamp wiring (wall switch is only connected to an AC cord, and can not provide power to the electronic circuit), a higher installation cost. The remote control dimmer can add as many advanced features, such as tone tone light. But the remote control is expensive, easily lost, and public places is inconvenient to use. To make matters worse, the electronic dimmers and remote control are lighting dimmer with the same label, so there is no uniform specifications. Not compatible with each other because each label, so the existing market is very small, the future is unlikely to be popular.


       SCR dimming without changing the wiring, the device costs are lower, the label silicon-controlled dimmer performance and specifications are not very different from European and American families generally installed silicon-controlled dimmer. Therefore, in the process of the commercial led lighting to replace incandescent, you must solve the problem with dimmer with triac dimmers. SCR dimmers LED dimming capabilities has also become a hot topic in the current market.


       At the same time, however, the SCR dimmer three inadequacies: first, the power factor will be worse, the shorter conduction angle, power factor, the more difference. Transferred to 1/4 bright, power factor will be lower than 0.25. Second, the efficiency will be worse, because in the dim, the load will cause the early closure of silicon control, causing the LED lights can not be stable jobs, a flickering problem. To solve the blinking problem, usually the installation of the bleeder resistor bleeder resistor power consumption in order to maintain the normal operation of the silicon control. In this way, waste of energy, contrary to the intent of the original dimmer energy-saving. At light loads, the efficiency of t he SCR dimmer system is only about 10%. , But also the existence of the matching problem to develop a market dozens of brands of SCR dimmer, dimmable LED lighting to ensure the compatibility of it is quite difficult.


       In summary, the current market conditions, at this stage, in order to replace the traditional lamps, led high bay lighting dimming technology development will be efficient, high compatibility SCR dimming solutions. However, after the LED into the mainstream lighting, which will develop the design of more efficient and convenient dimming technology for the LED light source characteristics.
