“…Linear dimming changes LED current directly to control the luminance, it does not have the above two drawbacks that exist in PWM dimming, but it requires putting analog factors into the design considerations and its power consumption is far greater than the PWM dimming. Besides, its color temperature variations become obvious for low brightness LED applications [4].…”

This paper studies spectrum optimization of four-package LEDs to improve performance of light sources with respect to properties such as luminous efficacy and colour rendering as well as luminous efficacy of radiation under photopic and mesopic conditions and circadian efficacy of radiation for non-visual biological effects. For colour mixing of four-package LEDs, the proportion of each LED in the package follows a linear relationship as does luminous efficacy. For optimization of luminous efficacy of radiation and circadian efficacy of radiation, an inverse proportion function model is proposed. An example of spectrum optimization for a four-package LED shows that by using the proposed model, high performance can be achieved with different weighting coefficients for different applications.
