Challenges in illumination design

The chromaticity of LED used as light source does not become the illumination color, so that ASA COLOR LED's "Customized LED" is optimum, as it can take into actual attributes of individual LED.


Adjustment to LED with low light intensity

Light shielding materials are added to caps to adjust appropriate light intensity.

Samples Conditions Light intensity (mcd) Chromaticity x Chromaticity y
1.No light shielding If=20mA 385 0.324 0.337
2.Light shielding Level 1 If=20mA 232 0.323 0.339
3.Light shielding Level 2 If=20mA 81 0.316 0.330
4.Light shielding Level 3 If=20mA 37 0.321 0.335


Chromaticity standards (standard specification)

* This information is just reference data of representative colors and guaranteed specification will be negotiated and finally defined in the delivery specification.


Example of standards (standard specification)

Items Marks Conditions Minimum Standard Maximum Unit
Light intensity IV IF=5mA 41 50 59 mc d


Items Marks Conditions Standard Range of chromaticity
Chromaticity IF=5mA 0.307 0.296 0.312 0.318 0.302
IF=5mA 0.315 0.315 0.334 0.315 0.296



1. No rank for both chromaticity and light intensity
2. Light intensity specification: Standard value +/- 18% approximately
3. Chromaticity specification: +/- 11/1000 approximately in the x direction


*The description above is based on standard specification of NHSB046-XX and NESB017-XX.

*Please consult us, as we can propose standard values to satisfy your needs.


Chromaticity distribution of our volume production products

The distribution of light intensity and chromaticity show normal distribution. Therefore, luminance deviations in and among lots can be eliminated.

Optical properties of narrow specification

The distribution of light intensity and chromaticity show normal distribution. That means luminance deviations in and among lots can be eliminated.
