LED lighting into the family to reduce costs is the key

LED home lighting can be divided into two aspects, one is to replace the traditional 40W/60W incandescent / fluorescent bulb, this on the one hand, consumers consider the demand mainly by price and energy saving effect; on the other hand is LED lighting model, such as the living room lamp, courtyard lamp, this part emphasizes the intelligent control and color temperature adjustment.

According to the price and energy saving requirements of the 40W/60W bulb bulb, LED power supply IC is being used in many ways to meet the needs of customers. Rich technology Liao Guangbin pointed out that the energy saving effect of high efficiency can significantly enhance the LED bulb, save electricity costs, LED lighting system cost analysis, improve the efficiency of power supply can save in the heat cost expenditure, greatly reduce the cost of the system.

Secondly, the simplification of the peripheral circuit components can also save the cost of the power module, reduce the power module area in order to increase the design flexibility of LED light source configuration and fin configuration.

Focus on intelligent control function

In the dimming and intelligent control part, pay attention to the design of new LED lamps, Liao Guangbin pointed out that household bulbs in Europe and the United States need to have both a wall mounted knob collocation dimming demand, it needs to take into account the existing system compatibility application circuit.

Accumulation of science and technology of lighting products director Yu Zhongwei said that the current accumulation in LED lighting has multiple AC to DC and DC to DC drive technology with emphasis on product line, high conversion efficiency, high power factor, safety and compatibility, support dimming. For dimming, he said that the application of dimming technology can enhance the competitiveness of their products, so the accumulation of positive development of dimming, in addition to provide related products in the PWM and TRIAC dimming aspects, also accumulated is also watching digital addressable lighting control interface (DALI, Digital Address Lighting Interface) development.

DALI is a new generation of lighting control interface standard, the standard interface can be easily integrated lighting systems in buildings, users can edit and adjust the scene illumination through the DALI interface, can realize the control of intelligent lamp intelligent building requirements easily. In addition, Yu Zhongwei pointed out that driving IC through more features (such as EMI protection integration), will be able to effectively reduce the cost of BOM customers.
