Embodiment 1

[0024] Such as figure 1 As shown, this embodiment discloses an intelligent light source with adjustable color temperature, which includes an LED light source 1, and the LED light source 1 is composed of a red LED 11, a green LED 12, and a blue LED 13 packaged together. The power supply terminals of the LED 12 and the blue LED 13 are respectively connected to a variable current power supply device whose output current can be adjusted arbitrarily. As can be seen from the figure, this embodiment adopts the common cathode connection mode, the cathodes of the three LEDs are combined to be grounded together, and the anodes of the three LEDs are respectively connected to a variable current power supply device, and the variable current power supply device is composed of an adjustable current IC 21 and an adjustable current power supply. The color temperature signal input device 22 constitutes; one pin of the adjustable current IC 21 is connected to the working voltage of the LED, and ...

Embodiment 2

[0026] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 lies in the power input connection mode of the LED light source. As shown in the figure, the anodes of three LEDs: red LED 11, green LED 12, and blue LED 13 are combined and connected to the same The terminal of the voltage source VCC, and the respective cathodes of the three LEDs are connected to a variable current power supply device.

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 [0001] The invention relates to an LED lamp, in particular to an intelligent light source with adjustable color temperature. Background technique [0002] At present, LED lighting fixtures use LEDs with different wavelengths and color temperatures as light sources. Generally, LED lamps are required to have different color temperatures according to the environment used by the user. [0003] The existing technology is to distribute LEDs of different color temperatures on the light-emitting surface of the lamp, and through the remote control device, the LEDs of the required color temperature are allowed to emit light, and at the same time, the LEDs of other color temperatures are turned off, so as to achieve the purpose of color temperature. [0004] In terms of working principle, this is a static color temperature, and there are only several fixed modes for temperature adjustment, so the types of LEDs with different color temperatures installed on the lamp are...
