 Why should LED strips and power supply supplies undergo aging test?
LED strips and power supplies are in the category of electrical and electronic products. Its aging test is mainly aimed at the aging of plastic materials. In the use of LED strips, the most important thing is to enable them to be used continuously under the maximum effect. The main factors affecting the normal use of LED lamps are dead light rate, heat dissipation and stable luminous efficiency. The main test method is to increase the voltage and current to complete.
Test the death rate of LED strips. Generally speaking, after the LED lamps are finished, the studio will not have problems under the rated voltage and current. Led light string led technology is advancing with each passing day, its luminous efficiency is making amazing breakthroughs, and prices are constantly decreasing. The era of a white LED entering the home is coming quickly. Impact resistant, strong lightning resistance, no ultraviolet (UV) and infrared (IR) radiation. No filament and glass casing, no traditional lamp tube fragmentation problem, no harm to the human body, no radiation. However, in the course of use, a short time of high voltage or a sudden power failure may inevitably occur. In order to ensure that the lamp can still work normally after this common situation occurs, it is necessary to test the LED lamp before leaving the factory. In order to check whether the power supply structure is qualified, the welding position is firm, and the bearing capacity of the assembly line has reached a certain standard.

Automatically switch the aging test for the power supply every 30 minutes. The aging time has been at least 6 hours.
The LED power supply and the light bar perform the heat dissipation test, and the heat dissipation performance of the LED power supply is directly related to the service life of the capacitor and the luminous efficiency of the light bar. A solar-powered light-emitting diode is a solid-state semiconductor device that converts electrical energy into visible light, which converts electricity directly into light. The heart of the LED is a semiconductor wafer with one end attached to a holder, one end being the negative pole and the other end connected to the positive pole of the power supply, so that the entire wafer is encapsulated by epoxy. The led lamp is an electroluminescent semiconductor material chip, which is cured with silver or white glue to the bracket, and then connected to the chip and the circuit board with silver wire or gold wire, and sealed with epoxy resin to protect the inner core wire. Function, and finally install the outer casing, so the LED lamp has good seismic performance. The LED can directly emit red, yellow, blue, green, cyan, orange, purple, and white light. The aging test method is to make the LED lamp reach its maximum load temperature for a certain period of time. Its internal structure will not be destroyed, and the temperature of each part of the LED lamp will not rise with the increase of the high-intensity working time for a certain period of time.
The LED lamp has high luminous efficiency and good stability. The main factor affecting the luminous efficiency and stability of the LED lamp is the voltage capability of the rectified part of the internal power supply. As long as the power quality is excellent, the general LED lamp can ensure high efficiency within its rated service life and Normal illumination. The general power supply will be equipped with an over-voltage automatic power-off device, which will not have a serious impact on the lamp bead, but will not be excluded. Since the LED light sheet may be wrong during the packaging process, it is necessary to perform a flash test to ensure stable, normal, and efficient operation of the LED light piece. Like other products,
The aging test principle of the LED constant voltage waterproof power supply is also the same, that is, the test capability in various situations that may be encountered in practical applications. The difference is in the way the test is done and the test process.
