However, LED bulbs with 95% efficiency have really appeared in the industry, underground parking lot lighting, and the solution is from a local LED driver supplier. This is Shenzhen Changyuntong Optoelectronic Technology Co., Ltd., which uses its originality. Sexual de-energy architecture technology has realized this industry miracle. More crucially, Wen Maoqiang, technical director of Changyun Optoelectronics Technology Co., Ltd. pointed out: "The 7W LED bulbs realized by this technology can not only achieve the BOM cost easily within 5 US dollars, but also the power factor can be 90. %the above."

The efficiency of LED bulbs you can see on the market today is basically up to 90%, regardless of which of the world's leading LED driver solutions suppliers or distributors. If you tell people that the efficiency of this LED bulb can be 95%, the underground parking lot lighting, basically all people will ask you: Are you talking about the efficiency of the DC-DC conversion part?
So, how does the de-powered architecture proposed by Changyuntong do this? Wen Maoqiang said that our core philosophy is to remove the transformers required for traditional LED lighting drive power supplies. Our approach is to first develop a 12V or 24V standard high voltage LED with Sanan Optoelectronics, and then package the LED constant current and protection circuit with several LED dies to minimize the BOM cost of the LED bulb. This architecture is actually similar to the LED of Seoul Semiconductor, but we have not integrated the AC-DC rectifier part into the special module of Changyun LED Bulb. The high-voltage LED concept of Epistar is similar to our philosophy. It uses multiple high-voltage LED combinations to effectively reduce the voltage difference between the output and the AC input, so that we no longer need to use lower efficiency and higher cost. A transformer with a large amount of heat and a large volume.
The energy conversion efficiency of today's conventional LED bulbs is mainly determined by the product of the following two parts of efficiency, namely: the efficiency of the AC-DC conversion part and the efficiency of the DC-DC constant current part. Although the energy conversion efficiency of these two parts can exceed 90%, the efficiency of the two parts is difficult to exceed 90%. The de-energized architecture effectively eliminates the AC-DC conversion part of the circuit, so the efficiency is greatly improved, and the underground parking lot is illuminated.
In terms of cost, the industry knows that the cost of LED light source is the main factor for the high cost of LED bulbs. Therefore, in recent years, the industry has been reducing the cost of LED light sources through various methods, such as continuously improving the brightness of LED light sources and developing with flip-chip technology. High-power LED light sources, high-voltage LEDs developed using high-voltage technology, and other substrate technologies (such as silicon carbide, silicon, and metals) that can replace sapphire to develop high-power LEDs.
LED bulbs with 95% efficiency and $5 retail price are no longer underground parking lights
