When Do We Need a Cold LED Emergency Driver?

5 views

In the past decade, emergency lighting has been increasingly applied in all kinds of public places around the world. With the continuous expansion of market demand and the growing maturity of industrial technology, more and more products with special properties have entered people’s life. The Cold LED Emergency Driver is one of the most representative ones.

On the earth we live together, there are different temperature zones from the poles to the equator, and different countries are located in different temperature zones. For countries which are located in the temperate zone, solutions for emergency lighting are undoubtedly the most convenient, as the mild climates present few extreme challenges.

However, for countries in extremely cold regions, take the northern Hemisphere as an example, such as northern Canada in North America, Russia in the north of Europe, and the four Nordic countries: Denmark, Sweden, Norway and Finland, the winter temperatures are generally below -30℃. In order to win precious time for people out of danger and subsequent maintenance, to maximize the protection of everyone’s life and property safety, the configuration of emergency lighting in public area is essential.

As we all know, when the ambient temperature of the battery is around 0℃or below, there will be some incomplete charging and discharging issues. So how to ensure emergency battery pack to be charged and discharged normally in these extremely low temperature environments has become the primary problem to be solved in the industry.

The existing low-temperature emergency drivers on the market declares that can be used at the minimum temperature of -20℃. These products typically use one of following two solutions:

1)  By adjusting the material formula of the battery cell, to achieve better low temperature resistance. However, due to the limitation of the material formula, the battery cell’s high temperature performance has been limited, usually can only reach +40℃. At the same time, the low-temperature battery cell is 2 to 3 times more expensive than the normal or high-temperature battery… These greatly limit the application scope.

2)  Select the conventional cell and add the heating system, but no insulation system. Under the normal mode, when the ambient temperature drops to a certain level, the heating system starts to heat the battery to ensure that the battery can be charged normally at low temperatures. However, because there is no reliable insulation system in the emergency device, when the mains power is off, the emergency drive enters the emergency mode, and the temperature around the battery will drop rapidly in the case of extremely low temperature, the battery discharge performance will be greatly reduced, and the emergency time of more than 90 minutes cannot be ensured.

Phenix Lighting's first Cold-Pack LED Emergency Driver 18430X-X series  was developed to address these issues.

To solve these issues, under the current technological background, the battery cell, real-time temperature detection and heat preservation material are the three most important factors. In addition to choosing the battery with good low temperature performance, Phenix Lighting also put a lot of effort into developing battery insulation materials. The working principle of the 18430X-X Cold-Pack LED Emergency Driver is to detect the temperature around the battery in real time, heat and keep the battery to a certain temperature so that the battery can be fully charged in normal mode and completely discharged in emergency mode. Therefore, the determining factor is to ensure that the ambient temperature around the battery can sustain battery discharge for more than 90 minutes when the external ambient temperature drops to very low and the system does not heat up. Through more than three years and thousands of experiments, compared the performance of different batteries and insulation materials, Phenix Lighting finally came up with the accurate and reliable curves of the battery running and environmental temperatures, so as to guarantee the product can work properly and be discharged over 90 minutes in emergency mode at -40℃.

Phenix Lighting 18430X-X series is the first Low temperature emergency led driver series in the world, which can guarantee minimum 90 minutes emergency time in wide temperature range from -40°C to +50°C. With its wide output voltage range from 10 to 400VDC, it is perfectly compatible with almost all AC LED luminiaires and DC LED loads. Constant emergency power output 9W/18W/27W optional, output current auto adjustable. 18430X-6 is IP66 rated and can be used directly in outdoor wet locations.
