Everlight Offers Low-Power LED with Overdrive Capabilities for Brighter LED Light Tubes

Everlight's 45-21S series is an upgrade from standard 3020 packages. With efficient thermal dissipation, this compact (3.0x2.0x0.8mm LxWxH) white LED can be overdriven up to 30mA or 60mA while maintaining high efficiency (115lm/W for the cool white and >104lm/W for the warm white versions), and cost effectiveness. These superior product characteristics turn the 45-21S LED into a real cost and energy saver and is a top solution for most general lighting applications, but especially for light bars or panel lights that need more brightness or require fewer LEDs.

Traditionally, light bar applications have been utilizing small 20mA PLCC packages that enable high lumen density and uniformity to emulate the appearance of fluorescent tubes. As the required specifications for fixtures in that market improved, light tube manufacturers are looking for ways to increase the brightness of their fixture without changing the board layout or any part of the mechanical design. The best way to do this is to use an LED that can be overdriven. Another reason for higher brightness PLCC packages are the efforts of some manufacturers to maintain minimum system brightness while decreasing the number of LEDs used. Thus, LEDs that can be overdriven make the entire tube more cost effective.

The Everlight 45-21S series has a CRI of >80Ra and is offered with ANSI CCTs ratings from 2700K to 6500K. This low-power LED provides a typical light output of 20lm (ww) and 22 lm (cw) at 60mA and achieves a very high luminous output of 26-41lm@75mA. The 45-21S package is Pb-free and RoHS compliant.
