The design of a good power supply must comprehensively consider these factors, because the power supply is as important as the human heart in the whole lamp. When LED is used as a display or other lighting equipment or backlight, it is necessary to drive it with constant current. The main reason is to avoid the drive current exceeding the maximum rating value and affecting its reliability.

LED without high quality radiator, then its life may be far less than the current ordinary energy-saving lamps! Because the light decline to the initial light flux of 70%, has marked the end of the life of LED energy-saving lamps.Power supply, whether through the high temperature and humidity, whether through the high voltage safety rules (UL), whether through the electromagnetic compatibility (EMC/EMI), are also some hard indicators, but also determines the real life of LED energy-saving lamp, barrel effect, power supply may be the short board of LED energy-saving lamp.

Many leds with high I value are not achieved by improving their own emission efficiency, but by lengthening the lens and narrowing the irradiation Angle. Although this is useful for LED flashlights, the observable Angle is also limited. In addition, for the same tubular LED, the I value of 5mm is more than twice that of 3mm, but only 1/4 of that of 10mm, because the larger the lens, the better the convergence characteristics. LED luminous Flux (F, Flux) : unit lumen, lm. The amount of light emitted by the light source in unit time is called the luminous flux of the light source.

To enhance the understanding of the critical role power supplies play in LED systems, it’s essential to delve deeper into their design and operational challenges. A high-quality power supply not only ensures the longevity and reliability of LEDs but also optimizes their performance across diverse applications, such as displays, general lighting, or backlighting. The necessity for constant current driving stems from the sensitivity of LEDs to current fluctuations; exceeding the maximum rating can lead to thermal runaway, accelerated degradation, or even catastrophic failure. This underscores the importance of precise current regulation in power supply design.
