The Challenges of Making Small LED Drivers
Over the past 10 years, LED chip technology has evolved rapidly. There are some large semiconductor manufacturers who are constantly involved in the development of LED chips with high luminous efficiency, and they are now capable of producing small-volume and high-efficiency LED chips (lumens per watt). The high performance of these LEDs led to the development of luminaire designs with sleek, slender, and other aesthetically pleasing case shapes. The development of high-power density power supplies has been a slow process for LED driver manufacturers. In other words, high-power density power supplies have a small volume and a high power density (watts per cubic). As the large volume of power supply limits the creative potential of luminaire designers, the need to reduce LED drivers is a priority. Reducing the size of the LED driver will reduce the size of the LED-driven heat sink. As a result, the temperature will rise, reducing the drive's lifespan. Despite the challenges associated with the development of small-volume power supplies, MOONS' has been operating in the field of LED drivers for more than a decade.
