Abstract
The invention relates to an LED (Light Emitting Diode) lamp and specifically discloses an intelligent light source with adjustable color temperature. The intelligent light source comprises an LED light source which comprises a red LED, a green LED and a blue LED, wherein variable-current power supply devices, of which the magnitude of the output current can be randomly adjusted, are respectively connected with the power ends of the red LED, the green LED and the blue LED. When the intelligent light source with adjustable color temperature is used, the purpose of randomly adjusting the color temperature is achieved by adjusting the output current of the variable-current power supply devices of the monochrome LEDs, and no additional LED light source is required for adjusting the color temperature, so that the intelligent light source is more flexible in mode for adjusting the color temperature and is lower in cost.
Description
Technical field
The present invention relates to a kind of LED light fixture, be specifically related to a kind of colour temperature adjustable intelligent light source.
Background technology
At present, the light source that adopts of LED lighting is that the LED of different wave length, different-colour is as illuminator.The environment that generally uses according to the user needs the LED light fixture that different colour temperatures is arranged.
Present existing technology is to be distributed in the LED of different-colour on the light-emitting area of light fixture, through remote control, lets the luminous work of colour temperature LED that needs, and closes the LED of other colour temperature simultaneously, and reaches the purpose of toning temperature.
Saying that from operation principle this is a kind of toning temperature of static state, have only several kinds of fixed mode temperature adjustments, is limited for the different-colour LED kind of on light fixture, installing therefore.In addition, this mode is in order to make LED light fixture colour temperature adjustable, thereby increased LED quantity, so this kind light fixture cost is higher.
Therefore, the cost of present colour temperature adjustable intelligent light source is high, and the warm mode of mixing colours is dumb.
Summary of the invention
In order to address the above problem, but the object of the present invention is to provide a kind of flexible colour temperature and the lower LED light fixture of cost.
For realizing the foregoing invention purpose, technical scheme that the present invention adopts is following:
A kind of colour temperature adjustable intelligent light source comprises led light source, and said led light source comprises a red LED, a green LED and blue led composition; Power end at said red LED, green LED and blue led connects the variable current supply unit that the big I of its output current is regulated arbitrarily respectively.
In the said colour temperature adjustable intelligent light source, said variable current supply unit comprises adjustable current IC and the toning temperature signal input apparatus that is connected with said adjustable current IC.
In the said colour temperature adjustable intelligent light source, said toning temperature signal input apparatus can be a remote controller, an adjustable resistance, an or controllable silicon dimmer.
The present invention adopts the three primary colours warm principle of mixing colours:
Adopt three primary-color LEDs of 1R1G1B (1 red 1 green 1 Huang) to form the led light source of LED light fixture; The only white that three primary colours are sent under certain situation; When the luminous quantity of any primary colours changes; The colour temperature of whole three primary light source will change, and through regulating the single-primary-color LED operating current of three primary colours, just can reach the colour temperature purpose that changes light fixture.
When the present invention uses, regulate the output current of the variable current supply unit of various monochromatic LEDs, just can reach the purpose of regulated at will colour temperature, do not regulate colour temperature and need not increase extra led light source.
Therefore, the present invention's warm mode of not only mixing colours is more flexible, and cost is lower.
