Fluorescent tubes are widely used in daily life, such as supermarkets, schools, office cities, subways, etc., but all public places that can be seen can see the use of fluorescent lamps! How to make the LED life and brightness reach the use The standard of satisfaction is a topic of considerable significance! The LED fluorescent lamp should maintain long life and high brightness. The problems to be solved are: power supply, LED light source, heat dissipation and safety.
1. The first requirement of the power supply is high efficiency and high efficiency. If the heat is low, the stability will be high. Generally, there are two schemes of isolation and non-isolation in the power supply part. The isolation volume is large and the efficiency is low. In use, there are many problems in installation. It is not as good as the market prospect of non-isolated products. Here we mainly discuss non-isolation. Drive solution.
2. The LED light source adopts the patented LED light source of Taiwan Mingmings. The chip is placed on the pin, and the thermal energy passes through the silver foot directly to the tropical part produced by the chip node, together with the traditional in-line product and the traditional patch. The product has different quality in heat dissipation, and the node temperature of the chip does not accumulate, thus ensuring the good use of the light source bead, ensuring the long life of the light source bead and low light decay.
Although the traditional patch products can be connected to the positive and negative electrodes through the gold wire of the chip, and the thermal energy generated by the chip is connected to the silver foot through the gold wire, the conduction of heat and electricity is conducted by money, and the heat accumulation time is long. Will directly affect the life of LED fluorescent tubes.
3. Heat dissipation Introducing infrared radiation heat into the fluorescent tube is an important means to improve the service life of the lamp. In the heat dissipation consideration, we separate the heat dissipation of the LED light source bead and the heat dissipation of the power supply, and do not interfere with each other, thereby ensuring the rationality of heat dissipation.
There are three ways of heat conduction, convection, conduction and radiation. In a closed environment, convection and conduction are less likely to be achieved, and the emission of heat by radiation is the focus of fluorescent tube considerations.
4. Safety and security, here mainly refers to PC flame-retardant plastic tube, because infrared heat can penetrate PC tube, we design to consider the safety of LED light when using it, use physical insulation of plastic, even The use of non-isolated power supplies also guarantees the safety of use.
The development of LED fluorescent lamps has been going on for quite a long time. From the perspective of energy saving, its future application is quite broad. In addition to energy saving, its safe and long-life use is something we should pay more attention to!
Safety! In the design of LED fluorescent lamps, it is the first element. The fluorescent lamps using PC flame retardant materials can improve the life after solving the safety problems. The solutions proposed by the above projects are expected to be provided to many LED fluorescent tube manufacturers. More ways to think!
