Embodiment Construction

[0079] The present invention provides a lighting controller and method in which light sources are activated in a repeating phenanthrene overlapping sequence for repeated durations. The end of the duration for one light source is detected to trigger switching on of the next light source in the sequence. This provides non-overlapping control of the light sources and provides an efficient and easy to implement required controller.

[0080] The following embodiments are all lighting devices based on three light sources. However, the invention can be applied to two light sources or to more than three light sources. Each light source may comprise a single LED or a string of LEDs. Furthermore, the present invention is not limited to LEDs, and the same concept can be applied to other light source devices. However, the invention is particularly applicable to LED lighting systems with two or more channels and where space for the driver is limited, such as linear light sources.

Abstract

A lighting controller and method has light sources which are activated for a respective lighting duration in a repeating non-overlapping sequence. The end of the lighting duration for one light source is detected for triggering the switching on of the next light source in the sequence. This provides non-overlapping control of the light sources and provides an efficient and easy to implement the required controller.

Description

technical field [0001] The invention relates to the control of lighting systems, in particular multi-channel light systems. Multiple channels can, for example, provide color mixing and color temperature control, although other effects can also be obtained by using multiple independently controllable light sources. Background technique [0002] Current multi-channel LED light sources, such as the Philips system known as "Smart TLED", face the main problem of limited space allocated to the driver. This system generates white light by independently driving red, green and blue LEDs. In practice, green LEDs utilize a natural blue LED and a green phosphor layer. The system produces warm white light with very high efficiency. Furthermore, multi-channel LED drivers are also encountered in LED modules or LED luminaires, where different channels are used to generate separate beams for general and task lighting, or separate LED strings are used to produce cool white or warm from a s...
