How to choose the high quality led driver for your lighting project? Sep 06
1. Drive mode
The first type: A constant voltage source supplies multiple constant current sources, and each constant current source individually supplies power to each LED.
Advantages: flexible combination, if one LED fails, it will not affect the normal operation of other LEDs.
Disadvantages: the cost will be slightly higher.
The second type: direct power supply with constant current, so that the LEDs can run in series or in parallel.
Advantages: The cost is slightly lower.
Disadvantages: poor flexibility, if one LED fails, the first thing to do is to solve the problem that it does not affect the operation of other LEDs.

2. High efficiency
Since LEDs are energy-saving products, the efficiency requirements of the drive power supply will be relatively high. It is especially important for the structure where the power supply is installed in the luminaire. Because the luminous efficiency of the LED will decrease with the increase of the LED temperature, the heat dissipation of the LED is very important. If the efficiency of the power supply is higher, its power consumption will be smaller, and the heat generated in the lamp will be smaller, thus reducing the temperature of the lamp, which is beneficial to delaying the light decay of the LED.

3, surge protection
The ability of LED to resist surges is relatively poor, especially the ability to resist reverse voltage, so it is very important to strengthen the protection in this area. Due to the initiation of the grid load and the induction of lightning strikes, various surges will be invaded from the grid system, and some of the surges will cause damage to the LED, so the LED drive power supply must suppress the intrusion of the surge and protect the LED from being damaged. ability.

4, protective measures
The life of the driving power supply should be matched with the life of the LED, and it should meet the requirements of installation rules and electromagnetic compatibility. The power supply structure must be waterproof and moisture-proof, and the outer shell must be resistant to sunlight. It is best to increase the negative feedback of the LED temperature in the constant current output to prevent the LED temperature from being too high.

In the end, SMARTS is specialize in all kinds of constant voltage or constant current led driver 12v 24v (mostly). And most of the led drivers got UL/cUL, ETL/cETL, FCC, SAA, CE, ROSH approval to meet most of the applications in North America, EU or AU matket. If you are looking for the right one,such as Bluetooth dimmable led driver, DMX512 dimmable driver, or WIFI dimmable led driver, Zigbee dimmable led driver. pls don’t hesitate to contact with us at
