Control circuit of lamp and lamp

Abstract

The invention discloses a control circuit of a lamp and the lamp. The control circuit comprises a driving power supply, a first switch assembly, a second switch assembly, a first light source, a second light source and a switching circuit. The driving power supply is connected with the input end of the first switch assembly, the input end of the second switch assembly and a first input end of theswitching circuit. The output end of the first switch assembly is connected with the input end of the first light source and a second input end of the switching circuit. The output end of the second switch assembly is connected with the input end of the second light source and a third input end of the switching circuit. The output end of the first light source and the output end of the second light source are grounded. When the first switch assembly is in a connected state and the second switch assembly is in a disconnected state, the first light source is lightened; when the second switch assembly is in a connected state and the first switch assembly is in a disconnected state, the second light source is lightened; when the first switch assembly and the second switch assembly are both ina connected state, the first light source and the second light source are both lightened.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a control circuit of a lamp and a lamp. Background technique [0002] With the development of society, LED lights have gradually entered people's lives. LED lights are widely used in many public places, such as billboards, roads, railway tunnels, bridges, squares, buildings and so on. [0003] However, currently used LEDs still have some deficiencies. For example, most LED lamps can only provide light with one color temperature when illuminating, and cannot provide light with a corresponding color temperature in different applications. If you want to change the light with different color temperatures, you can only replace different lamps, which will affect the user experience. Contents of the invention [0004] In view of this, the present invention provides a control circuit of a lamp and a lamp, which can change the color temperature value of the lamp according ...
