Abstract

The application provides a control device for a light emitting diode (LED) lamp. The control device comprises: an electronic controller, which is used for inputting, on the basis of external inputs, a high color temperature control signal, a low color temperature control signal and a light modulation control signal according to preset processing programs; a first group of LED illuminants; a second group of LED illuminants; a first variable output constant current source, which provides current outputs to the first group of LED illuminants; and a second variable output constant current source, which provides current outputs to the second group of LED illuminants. The first variable output constant current source provides final current outputs to the first group of LED illuminants according to the high color temperature control signal and the light modulation control signal. The second variable output constant current source provides final current outputs to the second group of LED illuminants according to the low color temperature control signal and the light modulation control signal. Color temperatures and brightness of LED illuminants can be controlled continuously or controlled in a multi-level manner, a comfortable illumination environment can be provided according to life needs of people, and energy is also effectively saved.

Description

technical field [0001] This application relates to the application and control field of lamps and lanterns using light-emitting diodes (LEDs). Multiple controlled color temperature adjustment ranges, and can achieve the effect that the color temperature does not change significantly when dimming. [0002] The application is beneficial to be used in domestic and commercial LED lamps or other lighting facilities. Background technique [0003] With the development of science and technology, semiconductor lighting technology has been widely used in various fields due to its characteristics of energy saving, environmental protection, and long life. voltage, lumen output and color temperature. [0004] For general lighting, it is hoped that LED lamps can be adjusted like ordinary lamps, and obtain lighting effects similar to sunlight or candlelight. This puts forward higher requirements for the color temperature and brightness adjustment of LED lamps. [0005] At present, seve...
