Hours of LED Life


LED Chips

The series incorporates best of best Nichia LEDs from Japan. The LEDs have the longest LED life and the best performance in the industry.

They are IES lM-80-2008 (Measuring Lumen Maintenance of LED Light Sources) certified for the best reliability and performance.

For eye safety, the LEDs are also IEC 62471:2008 (Photobiological Safety of Lamps and Lamp Systems) certificated.

Micro-Controller Controlled Operations

The whole system is software controlled by a single chip micro-controller. These include battery charging, discharge discharging, system changeover, fault protections, LED indications and infrared remote control.

The improves system reliability and makes the system smarter for the whole operations.


The system will perform automatic diagnostic for the control gear itself and also the battery conditions. It will start the diagnostic every month for the following test:

LED lamp
System changeover
Battery voltage
Battery discharge

Once fault is found, the red LED indicator will flash with different patterns for various error types.

IR Remote Control

The infrared remote control makes maintenance easier than ever. It can be used to set the LED exit sign system settings and self-test functions.

Panel brightness dimming control in normal operation
Flashing model in emergency mode
System changeover test (simulate traditional test button)
On-demand self-test

LED Indications

A rich set of LED indications provide feedback on the system’s status and faults. Operators can use this information to quickly identify and diagnose problems.

Light Guide Panel

Light guide panel is a transparent acrylic panel made from pure PMMA resin, on whose bottom face a dot matrix is printed. The light source is on its edge. It distributes the light coming from the light source evenly over the whole upper face of the acrylic panel.

Light guide panel is characterised by high uniformity of light and efficiency.
