DESCRIPTION

This device has been designed to meet the increasing
demand for InGaN technology.

The package of the VLMTG31.. is the PLCC-2.
It consists of a lead frame which is embedded in a

white thermoplast. The reflector inside this package is
filled up with clear epoxy.

APPLICATIONS

• Automotive: Backlighting in dashboards and
switches

• Telecommunication: Indicator and backlighting in
telephone and fax

• Indicator and backlight for audio and video equip­ment

• Indicator and backlight in office equipment

• Flat backlight for LCDs, switches and symbols

• General use
