In recent years the rapid development of high voltage LED lighting, in particular, landscape lighting, Beijing Olympics, Shanghai World Expo, a large number of applications of LED lighting, the aesthetic of the electro-optical unprecedented shock the senses of the world and popularization of energy-saving LED lighting, LED lighting in the world. Efficient, long life, environmentally friendly concept deeply rooted. Also high due to the cost of LED lighting, LED lamps and fluorescent energy-saving lamp market share of about 5% and 95%, LED lighting into millions of households to take up to 3-5 years.
The successful production of high-voltage high voltage LED lighting source for LED lighting has opened a new horizon, creating a new world. High-voltage LEDs module light source (HV LEDs), forward voltage VF compared LV led high bay hypertension, can be artificially controlled design in the production, the HV the LEDs on the same chip modules, which have been completed in the production PN junction on-chip series, the entire module VF, can be designed to 25V, 35V, 45V, 50V… 270V/DC, the LV LED ten times, several times. Positive operating voltage IF = 20mA, compared with LV LED 350-700mA operating current is reduced by one hundred times, therefore greatly reduce the HVLEDs heat, basically the high voltage LED lighting heat dissipation of the LV bottleneck, significantly reduce the use of the cooling aluminum. System circuit does not require a dedicated AC / DC switching constant current source, effectively reducing power consumption and cost.
