2. Product features
Rang Dong’s LED Downlight with battery backup turns on automatically when electricity is cut off. In this case, the downlight will change to battery-use mode. Lighting in blackouts lasts two hours. All the functions of the downlight are controlled by a chip produced by American NXP Semiconductors. This chip is integrated inside the light. Simultaneously, this chip controls the battery discharge, giving it a high reliability.
Moreover, Rang Dong’s Downlights with batteries contain high-voltage protection to shield the device during thunderstorms. They use the anti-burn Li-on battery proven reliability for backup devices. The battery operates a cycle with 1,000 times of discharge. It is eco-friendly and safe for humans.
LED Downlights are mounted on the ceiling of a corridor.
The lifetime of these downlights reaches 20,000 hours. That means we can use them for 8-10 years. Another specialty is a wide range of input voltage, from 170 VAC to 250 VAC. The luminous flux and power do not change when the input voltage swings within this range.
Furthermore, Rang Dong’s LED Downlight with battery backup does not release electromagnetic noise and also is not affected by the electromagnetic noise from the other electronic devices. The color rendering index of all LED lights made by Rang Dong is more than 80, those with battery backup.
These downlights all passed the standards of IEC 62776-2-1:2015 (Luminaire performance - Part 2-1: Particular requirements for LED luminaires) and IEC 60598-1: 2008 (Luminaires - Part 1: General requirements and tests).
