Fluorescent tubes have a wide range of applications, supermarkets, schools, office, city, subway, etc. in their daily lives, anything can appear with the public places, you can see the extensive use of the fluorescent How to make high power led life and brightness reached to a satisfactory standard, a considerable significance of the topic! LED fluorescent lamp to maintain long life and high brightness problem to be solved are: power supply, LED light, heat, security, four key technologies.
A. Power supply
Power first and foremost requirement is a high efficiency, high-efficiency products, heat stability is bound to. Usually two options in the power supply section useful for isolation and non-isolated, isolated volume is too large, and less efficient in use, the installation will have a lot of problems, as non-isolated products in the market prospects, we mainly discussed in this non-isolated the driver program.
Two. LED 400W source
Taiwan sulfur Cummings patent structure of the LED light source, its chips placed on a pin, heat silver pin directly to the chip node tropical out, with the-line products, and traditional product placement in the heat qualitatively different from the chip junction temperature is not cumulative, in order to ensure good use of the light source lamp beads, to ensure the long life of the light source lamp beads, low light.
Traditional patch products, through the gold wire connection of the chip is negative, heat is also generated by the chip over gold wire to the silver feet, the conduction of heat and electricity conduction money long thermal accumulation time a direct impact on the life of the LED 200W.
Infrared radiation heat is introduced and applied to the fluorescent tube, is an important means to increase lamp life. In consideration of the heat, we will separate the heat of the LED light source lamp beads, cooling and power, without disturbing each other so as to ensure thermal reasonable.
There are three ways of heat conduction, convection, conduction and radiation. Achieve in a closed environment, convection and conduction is likely to be smaller, heat dissipation by radiation, is considered the focus of fluorescent tubes.
Their safety security, this is mainly PC flame-retardant plastic tube, because the infrared heat can penetrate the PC pipe, we design considerations LED lights use can be considered more a physical plastic insulation, even in the use of non- The isolated power supply can absolutely guarantee the safety of use.
LED Blue 150W lamp has a rather long time, from the energy-saving effect, the face of its future application is very broad, in addition to energy saving, safe, long-life use, we should be concerned!
Safety! Is the first element in the design of LED fluorescent, fluorescent lamp using a PC fire-retardant materials, address security issues, how to improve the life of the above proposed solution to the number of LED fluorescent tube manufacturers to provide more way of thinking!
