Rohm announces the availability of compact high-performance, surface-mount LEDs with integrated lenses that help prevent light loss in automotive instrument clusters. The new product line includes 18 features, including the CSL0901 series with standard brightness and the CSL0902 series with high brightness.
The position of the light source in standard LEDs has been increased from 0,18 mm to 0,49 mm, which significantly reduces light losses to the environment. In addition, the size of the LEDs has been reduced by about 18 times compared to conventional reflector LEDs.
All LEDs are designed so that the brightness does not deteriorate even at high temperatures. For blue, green and white LEDs, a new kind of resin was developed. The company was able to improve the residual brightness compared to conventional products by about 85% during high-temperature tests with blue LEDs (20 ° C, IF = 1000 mA, 80 hours of operation). In addition, the high precision of the manufacturing process, while retaining the compact size of 1608, enables a five to seven times increase in core brightness over conventional LEDs.
