Recently, Nate's main push-free dimmable LED lamps have been put into the application of clothing store lighting. It cooperated with the lightmate company's laboratory in the United States to overcome the technical difficulties and developed the technology of LED chips using "AC technology" as the platform (none Drive lamps) get rid of the drawbacks of traditional LED, heat dissipation, life issues, to the greatest extent to solve the problems of clothing store lighting.
Recently, the non-driven dimmable LED lamps that are mainly promoted by Nateite Garment Lighting have been put into the application of clothing store lighting. They cooperated with the lightmate company's laboratory in the United States to overcome the technical difficulties and developed the technology of LED chips using "AC technology" as the platform. (No drive lamps) get rid of the drawbacks of traditional LED, heat dissipation, life issues, to the greatest extent to solve the problems of clothing store lighting.
LED light source has attracted much attention and rapid development as a fourth-generation lighting fixture that is green, energy-saving, energy-saving, and long-life. The current LED light source is a semiconductor device operating at a low voltage (VF=2→3.6V) and a large current (IF=200→1500mA), and a suitable direct current must be supplied to properly emit light. The technology of direct current (DC) driving LED light source has become more and more mature. Since the power supply used in our daily lighting is high voltage alternating current (AC100-220V), we must use the step-down technology to obtain lower voltage. The commonly used transformer is the transformer. Or the switching power supply is stepped down, and then the alternating current (AC) is converted into direct current (DC), and then converted into a direct current constant current source to cause the LED light source to emit light. Therefore, the system application of DC-driven LED light source must be: transformer + rectification (or switching power supply) + constant current source (Figure 1). LED lamps must have a certain amount of space to house this module, but for E27 standard screw luminaires, the space is very limited and difficult to place. Whether it is via transformer + rectification or switching power supply step-down, the system will have a certain amount of loss. When the DC LED is switched between AC and DC, about 15 to 30% of the power is lost, and the system efficiency is difficult to achieve more than 90%. If the LED light source can be directly driven by alternating current (AC), the system application scheme will be greatly simplified, and the system efficiency will easily reach more than 90%.
Seoul Semiconductor Co., Ltd., today's Seoul Semiconductor, invented AC LEDs that can be directly driven by AC power in 2005, followed by III-N Technology in the United States, and 3N technology to develop a gallium nitride substrate based on MOCVD growth technology. Improve lighting and sensor applications, reduce costs and increase productivity. 6-inch production technology for large and small silicon LEDs. Nate's clothing lighting is also the first step in the era of cooperation with the US lightmate company's laboratory to complete the AC non-drive dimmable LED products, to solve the shortcomings of existing LEDs can not be directly used under AC power, resulting in higher product application costs. It has more energy-saving, longer life and more energy-efficient.
