Surface-Mount High-Brightness LED Lamp : TLWD1100B
Designated the TLWD1100B, the new high-brightness white LED lamp is compatible with Pb-free reflow soldering and suitable for automotive interior, LCD backlighting and various indicator applications.
The TLWD1100B is otherwise identical to its predecessor, TLWD1100, in terms of optoelectrical characteristics, reliability, packaging and applications.
Features
- Luminous intensity: 180 mcd (typ.)
Chromaticity coordinates: Cx = 0.32, Cy = 0.31 (typ.)
@Ta = 25 °C, IF = 20 mA - RoHS-compatible
- Suitable for applications that require high brightness at high temperatures (see the derating characteristics).
Application Examples
- Backlighting for various applications
(automotive interiors, LCD panels, various switches, etc.) - Indicators on small-sized equipment
- Decorative lighting for amusement equipment

- Precautions
-
- The TLWD1100B is sensitive to electrostatic discharge and should be handled with care. If the TLWD1100B is exposed to an overvoltage condition, it may be damaged (or permanently destroyed) by its energy.
- Since the TLWD1100B Series is intended to be used for display lighting, the measurement standard is based on the sensitivity of the human eye. It is not intended to be used for applications other than display lighting (e.g.., sensors and optical communication systems).
