Challenges in illumination design

The chromaticity of LED used as light source does not become the illumination color, so that ASA COLOR 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

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

Chromaticity distribution

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