Embodiment Construction

[0024] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] As mentioned in the background art, in the prior art, after the light-emitting diode is manufactured, the color temperature of the emitted light cannot be adjusted, which cannot meet people's dynamic requirements for light-emitting devices with different color temperatures.

[0026] To solve the above problems, the present invention provides a lighting device, which includes a first lighting unit, a second lighting unit, and a controller for the second lighting unit. Wherein, the first light emitting unit is used for emitting white light, the second light emitting unit is used for emitting light of a single color, and the controller of the second light emitting unit is used for changing the light intensity of the second light emi...

Abstract

The invention discloses a luminous device, which comprises a substrate, a first luminous unit, a second luminous unit and a second luminous unit controller. The first luminous unit is arranged on the substrate and used for emitting white light; the second luminous unit is arranged on the substrate and used for emitting the light with one color; the second luminous unit controller is electrically connected with the second luminous unit and used for changing the luminous intensity of the second luminous unit; and the emergent light of the luminous device is the light which is formed by mixing the white light and the light with the one color. The light with the one color sent by the second luminous unit can change the luminous intensity under the control of the second luminous unit controller so as to change the proportion of the luminous intensity of the white light and the light with the one color. The light with the one color is mixed with the white light emitted by the first luminous unit to form the white light with different color temperature so as to meet dynamic requirements of people on different color temperature.

Description

technical field [0001] The invention relates to the field of semiconductor light emitting, in particular to a light emitting device. Background technique [0002] Light Emitting Diode (LED, Light Emitting Diode) is used in various fields due to its advantages of long life and low energy consumption, especially as its lighting performance index is greatly improved day by day, LED is often used as a light emitting device in the lighting field. [0003] Because LED light is limited to basic colors such as red, blue, yellow and green. In order to obtain a white LED lighting source, a variety of technical solutions for obtaining white light have been developed in this field. A Chinese patent with the notification number CN100438026C discloses a white light emitting diode. Refer to figure 1 , shows a schematic diagram of the light-emitting diode in the patent, the light-emitting diode 10 includes: a first light-emitting chip 12 , a second light-emitting chip 14 , a third light-em...
