The personage inside all know, led strip lights will become a new generation of energy conservation and environmental protection lights, but now the whole country each year hundreds of thousands of teams at most production LED fluorescent lamp, and most of the export, the domestic use very few, actually the main question is the question of price, a common energy-saving fluorescent tubes ten yuan money is enough, and a root LED fluorescent tubes have to hundreds of pieces.
The industry insiders know, flexible led strip will become a new generation of energy conservation and environmental protection lights, but now the whole country each year hundreds of thousands of teams at most production LED fluorescent lamp, and most of the export, the domestic use very few, actually the main question is the question of price, a common energy-saving fluorescent tubes ten yuan money is enough, and a root LED fluorescent tubes have to hundreds of pieces. So the current fluorescent tubes is mainly by commercial lighting give priority to. Because the commercial lighting more will be considered the energy conservation, the environmental protection, image, the government support, etc.
But now LED Light Bars product quality is uneven, some even fluorescent lamp life than, useless, as users to know more and more deep products LED fluorescent lamp, fluorescent lamp manufacturers need to resolve LED to the following problems:
First, the drive power constant current driver problems. At present most constant current source is mostly always constant current (also is more parallel light string of sharing a constant current source, because LED lights between the difference of the resistance of the pearl, so each ChuanDeng current size to differ, any a LED lamp is out of order, will affect the other lights string of current so current big those lamp light failure of more serious, its service life greatly will also cut short.)
Second, heat dissipation problems. This is the service life of the fluorescent tubes LED one of the core problems. Currently each manufacturer mostly follow suit with built-in power, to direct can change to fluorescent tubes on the support, so that you have the power to send out quantity of heat to send out quantity of heat and LED itself in an aluminum shell on cooling, and in fluorescent tube, the quantity of heat that how to deal with?
Third, the power modules of electrolytic service life problem? Even if we use the long life electrolytic capacitor, in the high temperature to work, it also can’t and LED the life of the life of the phase equilibrium. But how to provide good working temperature, in order to achieve the most ideal life?
Fourth, the power modules of stability and product safety certification if I can pass the question? Most factories on the market at present the high pressure and isolation scheme is not, and high pressure against type day off power solutions, because the built-in volume is very limited (to put in the tube), so average in the design, it is difficult to put the power do stability. And the various countries to safe authentication are strictly, for high voltage power supply of the safety certification as more difficult to pass.
In fact, the problem above the root of the main to or in the built-in power generated!
Below are some professional people about built-in power and external power source design of the performance of the fluorescent tubes compared:
The power of the fluorescent lamp LED into the built-in and outer type two kinds. The so-called built-in means power can be put inside tubes. The built-in the biggest advantage is that it can be made directly replace existing fluorescent tubes, without giving any changes. So the shape of the built-in is made runner, so that plug into the semicircular tubes.
