First, after LED lamps are produced, dim light, flicker, failure, intermittent lighting and other phenomena often occur, and sometimes the products are not bright at all. The service life of LED lamps can't reach the expected length, which affects the quality of LED products. There are three main reasons for the above phenomenon of LED. They are:

1. When LED is used as the product, there are some problems in the welding process, such as too high welding temperature, too long welding time and poor antistatic work. These are all caused by imperfect management in the process of LED packaging.

2. The quality of the LED itself or the poor quality of the LED caused by the manufacturing process.

3. The heart of the LED lamp-the quality of the LED driver itself is problematic.

Second, in order to prevent LED lamps from being damaged due to LED quality problems, or to prevent LED lamps from being damaged in the packaging process, we generally take three preventive measures. 1. Before assembling the LED lamp, the LED driver shall be subjected to aging test to ensure that the LED driver is in good condition before assembly. 2. Control the welding manufacturing process. 3. Use LED aging line to test the aging of LED products. Among them, the aging test with LED aging line is an essential link in the production of LED lamps, and the aging test of LED products is an important measure to ensure the reliability of electronic products and the last essential step in product production.

Thirdly, the use of LED aging line in LED lamps can improve the efficiency after aging, which is helpful to the stability of efficiency in later use. LED aging test is based on the characteristics of product failure rate curve, that is, bathtub curve, in order to improve the reliability of products. Aging test is at the expense of the life of a single LED product, but on the premise of winning the reputation of customers.

Four, LED aging test includes two ways: constant current aging and constant voltage aging.

Constant current aging is the most scientific method of LED aging, which accords with the working characteristics of LED current. Over-current impact aging is also the latest aging method adopted by manufacturers. By using a constant current source with adjustable frequency and current, this kind of aging can be carried out, so as to judge the quality life of LEDs in a short time and pick out many hidden LEDs that can not be picked out by conventional aging.

Effectively prevent individual LEDs in LED products from being shoddy.

Verb (abbreviation of verb) In a word, if LED lamp manufacturers want to survive in the future, it is essential to age the LED aging line of LED lamps in the production process, which is the guarantee of LED lamp product quality.
