Strong points of ELGS 1

ELGS allows line illuminations instead of spot illuminations only with LED.

Point source Homogeneous strip

(14)

Strong points of ELGS 2

ELGS can be used for line illuminations with a simple circuit having an LED, no need for many LEDs.

There is no need for sorting the same brightness and chromaticity for LEDs.

Strong points of ELGS 3

Advantages to acrylic resin plate

Only the left-side LED lights (the right-side LED turned off)

Sufficient brightness at the far position of the radiation point(LED)

ELGS

Dark Unlighted

U pattern acrylic resin plate

Further R&D

* Diffusing board (mirror board)

Research a possibility of ELGS, we suggest new style illuminations.
