The Ultimate Buyer's Guide for Purchasing PHILIPS Dali Driver

• high reliability

Especially the driving power of the LED street lamp is installed at a high altitude, so the maintenance is not convenient, and the cost of maintenance is also large.

BMT supply professional and honest service.

• high efficiency

LED is an energy-saving product, and the efficiency of driving power is high. It is very important for the power to be installed in the luminaire. The power supply’s efficiency is high, but the power consumption is small, and the heat in the luminaire is small, so the temperature rise of the lamp is also reduced. As a result, delaying LED attenuation is advantageous.

•  high power factors

The power factor is the power grid’s demand for the load. In general, there are no mandatory indicators for electrical appliances with a power rating of fewer than 70 watts. Although the power factor of a single electric appliance is low, it has little influence on the power grid; however, in the evening, the power grid will be seriously polluted by a large amount of lighting and the concentration of the same kind of load. There may be some index requirements for power factors for the 30 watts-40 watts LED driver in the near future.

• driving mode

Now there are two kinds of traffic: one is a constant voltage source for multiple constant current sources, and each constant current source is supplied to each LED individually. In this way, the combination is flexible, and all the LED failures do not affect the work of other LEDs, but the cost will be slightly higher. The other is the direct constant current power supply, that is, the drive mode of “Keke Hui Bao”, which is driven by LED in series or parallel operation. It has the advantage of low cost but poor flexibility, and it also does not affect other LED operation problems when solving an LED failure. The two forms coexist in a period of time. The way of multi-way constant current output power will be better in terms of cost and performance. Maybe it’s the main direction in the future.

•  surge protection

The ability of LED to resist surge is relatively poor, especially the ability to resist reverse voltage. It is also important to strengthen the protection in this area. Some LED lights are outdoors, such as LED street lights. Because of the load shedding and lightning induction, all kinds of surges will be invaded from the power grid, and some surges will cause LED damage. Therefore, the analysis of the driving power of “Zhongke Hui Bao” should be deficient in surge protection. As for the frequent replacement of power and lamps, the LED driver should have the ability to suppress the surge and protect the LED from being damaged.

• protection function

To meet the requirements of safety and electromagnetic compatibility, it is best to increase the LED temperature negative feedback in the constant current output, in addition to the conventional protection.
