I am a switching power supply. I used to be an adapter, a charger, and an iron-shell switching power supply. Later, I did LED power, and I started to do some 1W, 3W high-power LED drivers , but I did less. The reason is simple, there is no market. I found that high-power LED constant current power supply, as long as its power exceeds 5W, there is basically no market, only proofing. Because the LED is too expensive. This is also considered to be a wake-up call for friends who are doing power supply. This is my experience. I do not know how many people have fallen into high-power LEDs, high-power LED thunder is loud, rain is small, and many of them are lost in this piece. Still a small power LED market is better. But it doesn't work either. Now the low-power LED driver is blocked by most of the resistor-reducing power supplies. The constant current switching power supply drives the low-power LED, which is good, that is, many people can't accept the cost. I have a constant current type low power LED driver, switching power supply, the efficiency reaches 0.9, stability reliability, constant current accuracy are very good, the price is only five yuan, but many people are still too expensive, because They compare it with a one-way resistance-reducing step-down power supply, of course, the two are simply incomparable. Inside the switching power supply I have, there is an integrated MOS switching power supply chip and a transformer. The cost of the two is put there, of course, the performance is also there. But I believe that the final low-power LED constant current driver will eliminate the RC capacitor. Because consumers will gradually become more rational, a luminaire that is made of a resistor-reducing buck power supply has almost no practical value. It can only be used as a display and toy. If the LED really enters the field of general illumination, the resistance is reduced. The voltage source is simply not up to the task. I can expect that in the future, as the performance of LEDs increases, the price will decrease, and the cost of power will become a very important part of the cost of LED lamps. The real luminaire, the resistance to the pressure drop is simply not competent. Resistor-capacitor buck power supply is popular, just a transition, and finally the constant current power supply is authentic.
I am still optimistic about low-power LED lamps. Low-power LED lights, currently mainly due to too much light decay, the price is not ideal. But now it is still superior to high power for general lighting. I think that low-power LED lamps enter the field of general lighting, and with energy-saving lamps, it will be within five years. The entry of high-power LEDs into general-purpose lighting is certainly something beyond five years. So now I focus on the development and production of low power LEDs. I noticed that the lamps used in general lighting for low-power LEDs are mainly LED desk lamps, LED honeycomb lamps, and LED fluorescent lamps . Especially for LED fluorescent lamps, since the second half of 2007, many people have started research and development, and it can be said that the heat is incredible. Basically, there are eight of the ten people who are looking for me now, so I started to do the power supply of LED fluorescent lamps for a while, so I would like to talk about the development and production of this kind of power supply. Methods and principles. What the individual has experienced.
About the shape
Now LED fluorescent lamp power supply, manufacturers of lamps are generally required to be placed in the lamp, such as in the T8 lamp. Very few are external. I don't know why this is the case. In fact, the built-in power supply is difficult to do, and the performance is not good. But I don't know why there are so many people asking for it. It may be down with the wind. The external power supply should be said to be more scientific and more convenient. But I also have to fall with the wind, what the customer wants, I will do. But doing the built-in power supply is quite difficult. Because the external power supply, the shape is basically not required, how much you want to do, and what shape you want to make does not matter. The built-in power supply can only be made into two types, one is the most used, that is, placed under the light board, the light board is placed on the top, and the power supply is below, so that the power supply is required to be thin, otherwise it cannot be installed. Moreover, the component can only be dropped, and the line on the power supply is only lengthened. I don't think this is a good idea. However, everyone generally likes to do this. I will do it. There is also less use, put the two ends, that is, placed on both ends of the lamp, so that it is better to do, the cost is lower. I have also done it, basically the two built-in shapes.
Car Accessories is a new field of our company develop, which including the USB Charger Socket, LED Light , Car Lighter Plug and etc.
The USB Car Charger is available in many different modal, there is round and rectangle shape. The bottom of this USB Charger could be solder terminal also could be wiring. All the input and output are direct current and it is normally applied in the Marine, Truck, Camper, motor home, boat etc.
The LED Light is IP56 waterproof rating, which could better protect the LED Bulb from the water or harsh environment. Energy Saving
LED Lamp could not only used in RV but also could use in many other application of Marine, Truck, Camper, motor home, Limousine, Travel trailer, caravan, boat etc. There are 12V DC 24VDC Voltage could be choose from. The Emitting Color could choose, including Red, White, Blue and etc. The Working life of the Ceiling Light is 30,000 Hours, which is a long time for use.
Cigarette Lighter Plug is also available in many modals, the input and output are direct current and it is normally applied in the Marine, Truck, Camper, motor home, boat etc.Normally fits 18AWG wire cable
