The heart of the LED drive power supply, LED energy-saving lamps
Date: Publisher:

Has long been a driver circuit is an important part of LED application products, LED drive power supply is one of the power supply series products of many species, belong to is to provide LED lighting lamps and lanterns, LED electronic equipment power device, also known as drive power supply, it is to provide energy saving lamps and lanterns lighting electricity and to provide computer related parts need electricity. Are widely used in: LED lights, LED grille lamp, LED interior lights, LED ceiling lamp, building lighting, road and bridge lighting, information graphic display: display board, billboards, dynamic simulation animation, sports venues, car lights and internal reading lamp, car brake lights, tail lights, lights, side lights, explosion-proof lamps, miner's lamp in mining production, etc.

In recent years, the led packaging technology and the continuous development of cooling technology, the stability of the led lights have reached a good level, droop and color drift is mainly some fake products manufacturers, the main reason is that heat dissipation design is not reasonable. As directly restricted the quality of LED drive power LED strong sex, and follow the development of LED industry, LED drive power supply is also gradually mature.

Usually when choosing and design LED drive power supply should consider the following:

  1. Main features high efficiency LED products is energy-saving, so the efficiency of the driving power supply must be high. For the structure of the power supply installed in the lamps and lanterns, is very important. The LED luminous efficiency is increased with the LED temperature decreases, so the LED heat dissipation is very important. The power efficiency is high, its power consumption is small, calorific value is small, also lower the temperature of lamps and lanterns. Good for delaying the LED light failure.
  2. High power factor power factor is the requirement of load of power grid. Generally below 70 watts of electrical appliances, there is no mandatory provisions of the state. Though the power of a single use lower electric power factor, the impact on the grid is not big, but at night you light a lamp and its load is too concentrated, can produce serious pollution to grid. For 30 ~ 40 watts of the LED drive power supply, power factors may have certain index requirements.
  3. High reliability especially like LED street lamp driver power supply, in a sealed environment, high maintenance is not convenient, the cost of maintenance is also big.

The driving mode of 4. Popular now have two kinds: one is a constant voltage source for multiple constant current source, each constant-current source separate for each LED power supply. This way, flexible combination, LED failure all the way, don't affect the work of other leds, but the cost would be slightly higher. The other is a constant current power supply directly, leds in series or parallel operation. It has the advantage of low cost, but poor flexibility, but also solve a LED failure, does not affect other LED running problem. These two forms, for a period of time. Multi-channel constant current output power supply way, in terms of cost and performance will be better. Maybe the mainstream direction of the future.

  1. Surge protection The only under specific environment requires more. LED the ability of anti surge is relatively poor, especially the reverse voltage resistance. Strengthening the protection is also very important. Some LED lights installed outdoors, such as the LED street light. As a result of the power grid load and sling and lightning induction, into the various surge from the grid system and some surge can cause the damage of the LED. So the LED drive power to suppress surge intrusion, ability to protect the LED was damaged.
  2. Protection function Power supply in addition to conventional protection function, it is better to add the LED temperature in the constant current output feedback, prevent LED temperature is too high.
  3. Protection Some environment type lamps and lanterns is installed outside, the power supply structure to waterproof, moistureproof, shell to fast.
  4. The life of the drive power supply and LED the life of the adapter.
  5. To conform to the requirements of safety and electromagnetic compatibility

LED device of the drive power close to demanding, incandescent bulb LED lights are not as popular and can directly connect 220 v ac mains. LED is 2 ~ 3 v low voltage driver, necessary to design complex conversion circuit, different use of LED lights, equipment of the power adapter.
