Factory-use, Workshop explosion proof lamp power supply appl

       The so-called factory-use explosion-proof lamp is the explosion-proof lamp used in factories or workshops. The main function of the explosion-proof lamp is the lighting effect with explosion-proof protection. Explosion-proof lamps are used in many hazardous production environments, and factory explosion-proof lamps usually require a rigorous power supply design for better security. Then what should be paid attention to when designing the explosion-proof lamp power supply for the factory?

The Factory-use explosion-proof lamp power supply should pay attention to:

1. Factory-use explosion-proof lamp power supply requires constant current output

The characteristics of the LED lighting material determine that the power supply of the explosion-proof lamp is greatly affected by the environment. For example, if the temperature changes, the current of the LED driver will increase, the voltage will increase, and the current of the LED will increase. Working over the rated current for a long time will greatly shorten the life of the LED lamp. The constant current of the LED is to ensure that the operating current value is constant during the influence of environmental factors such as temperature and voltage, to stabilize the life.

2. Factory-use explosion-proof lamp power supplys constant current accurate value is important

The constant current accuracy of some power supply on the market is poor, some the constant current solution on the market has an current error of ±15% , the constant current range is too large. The general requirement is ±8%, according to the 8% design, the production power supply should be fine-tuned to achieve ±8% error.

s working voltage

The recommended operating voltage of general LED is 3.0-3.5V. After testing, most of the work condition is at 3.2V, so it is reasonable to calculate according to 3.2V, total voltage of N lamp beads in series = 3.2*N.

4. If the factory-use explosion-proof lamp power supply need to be isolated or non-isolated?

Generally, if the isolated power supply is made with 30w, it is placed into the power supply tube of the factory-use explosion-proof lamp. The transformer size is very large and difficult to put in. Mainly depends on the specific structure of the space, the isolation can only be achieved 30W, if power more than 30W,  the price is very expensive. Therefore, the cost performance of isolation ed one is not high, generally non-isolated is more mainstream, the volume can be made smaller, the minimum can be as high as 8 mm, in fact, non-isolated security measures are done, there is no problem. Isolated power supply can be use if the space is enough.

5. Pay attention to the factory-use explosion-proof lamp power supply cooling situation
The main factor of the heat dissipation solution is that the factory-use explosion-proof lamp power beads can greatly extend the life when used under the conditions of explosion-proof lamps in non thermal. Generally, aluminum alloy is used, which is easier to dissipate heat. That is to say, the factory-use explosion-proof lamp power beads on the aluminum substrate, and the external heat dissipation area is maximized.

The above five points are matters what needed to be pay attention to in the design of the factory-use explosion-proof lamp power supply. No matter what kind of industry, when choosing the factory-use explosion-proof lamp, we must pay attention to the above matters to help the enterprise choose the explosion-proof lamp suitable for its own company. Explosion-proof lamps are lighting equipment in flammable and explosive areas, which is indispensable for every flammable and explosive dangerous places. Therefore, enterprises must be cautious in selecting explosion-proof lamps.
