Traditional energy-saving lamps and LED horizontal plug-in lamps (LED plug-in tubes)

The LED horizontal insertion lamp does not need to be re-punched, and does not need to waste the lamp cover of the previous downlight, which greatly reduces the cost and reduces the trouble caused by the installation.
The early LED horizontal plug-in power supply mostly used non-isolated. The biggest disadvantage of non-isolation is that the output has high voltage. If the design is unreasonable, the output is not protected, and it is easy to appear LED dead light. More serious is if there is no shell and aluminum substrate. Isolation is good, it is easy to leak and electric shock.
Therefore, if you want to design a good LED horizontal plug-in power supply, you can use the isolated power supply for the long-term stable operation of the horizontal plug-in lamp, but the cost of the isolated power supply is relatively high, and the design is more difficult, especially A large number of stable power supplies are even more difficult. The most effective way to verify that the power supply is stable and unstable is to illuminate for a long time and light up for a long time in a high temperature environment.
The power supply only passes the long-term aging test, and the problem is solved continuously. The problem can be solved stably. Many LED horizontal plug-in lamps have high power input voltage, and the power supply is not working properly, and there will be rapid flicker. Many LED lamps have a nominal voltage of 85-265V. Some inferior electronic components do not meet this requirement, so there will be flicker. Of course, the design scheme is unreasonable. When the voltage is high, the parameters do not match, and the high frequency appears. Flashing, such a problem is also fatal in many household appliances, because the input current is large at the moment of opening. It is easy to damage the luminaire, and the impact power supply will be protected to prevent damage. However, it will also increase some costs. Therefore, when aging, we will add a process, which is impact aging.
Nowadays, the LED downlights and ceiling lamps on the market have found an amazing secret when chatting with friends who are doing traditional lighting products. The export volume of traditional horizontal insertion lamps is at least 500 million a year, and the domestic sales volume reaches 100 million. More than one, why don't we make the plug-in tube inside the LED plug-in tube? The downlight housing can be equipped with your LED plug-in tube is not very good, the sales volume is so large, the cost is low, the LED horizontal plug light has more advantages than the ceiling light and the down light.
