Self-ballasted LED Lamps for General Lighting

Posted by waterled on April 15th, 2021

The situation is alarming. Solar led light Manufacturers competition has become fierce, and product prices continue to fall. Comparing the Vf BIN distribution table of lamp beads, it is not difficult to find that without effective BIN mixing measures, nearly half of the lamp beads cannot be used in mass production, and the cost of lamp beads purchases indirectly increased significantly. In the unqualified test items, the actual test power of the lamp and the declared power of the product do not meet a large proportion. A low-price strategy that sacrifices product quality or even violates industry norms and regulations is not advisable.

The high incidence of 'quality gate' incidents has seriously damaged the company's own image and the brand image of my country's LED industry on the international stage. The author believes that the first three reasons directly reflect the lack of quality awareness of the manufacturer and have little relevance to the design.

Technical personnel in the LED China Street Lamps Factory industry must explore low-cost solutions under the premise of meeting product quality requirements, so that ordinary people can afford high-quality LED lighting products. As early as 2010, my country has issued the national standard GB/T24908-2010 'Performance Requirements for Self-ballasted LED Lamps for General Lighting',

Article 5. This article takes the LED lamp power deviation out of control as an example, theoretical calculations combined with case calculations, detailed analysis of the constant current accuracy of the driving power supply, and the influence of the LED forward voltage drop distribution on the lamp power deviation, for the reference of designers to improve the design quality of LED products. If the constant current accuracy is 1%, the minimum voltage drop of the lamp string is required to be 32.8%,
