LED lighting to enhance the stability

The current market is flooded with LED lighting products, their power input system into two categories: one for the front of the rear end of the AC power input system coupled with the constant current control module, such products include freezer lights, indoor lighting, street lights, lamp, MR16, AR111, etc. Another direct input AC power system integration AC / DC converter and a constant current circuit, including products such as E27 and GU10 LED lamp bulbs, PAR lamps, T5 and T8LED lamps, and so on.

The first category should be selected in addition to the front-end power supply design better efficiency constant-voltage power supply, the back-end constant power supply module is controlled by the use of product characteristics according to their efficiency better power supply design. The advantage is that the front-end AC / DC power supply, such as switching power supplies, DC adapter, such as constant-voltage power supply, optional high and more than a safety certification program, designed to reduce the threshold.

The second class of power supply design due to the integration of the AC / DC circuit and a constant current circuit, it can meet the design space of the smaller agencies, but the power factor, power efficiency, and safety considerations, the design also has some difficulty. Therefore, very few such products on the market today can achieve high luminous efficiency, high power factor ( > 0.9 ) standard. led grow lights https://www.eneltec-led.com/products/led-grow-lights

Currently LED lighting products to achieve high luminous efficiency, and become the next generation of the main light source, the primary consideration in the design of the power modules for different products to choose the right lighting design architecture. In addition, the power supply control IC must also improve power efficiency, power factor, reliability, to develop demand for LED lighting products. best led headlights http://bestledheadlight.com/
