Embodiment Construction
[0016] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0017] Dimming circuit embodiment
[0018] The present invention proposes a dimming circuit, which includes: a power supply module 1, a control module 2, an indication module 3 and a triac Q2. The power supply module 1 is used to convert AC power to DC power, the control module 2 outputs an adjustment signal, the bidirectional thyristor Q2 is controlled by the control module 2, and the indicating module 3 is used to indicate whether the circuit is connected. The power supply module 1 includes an input terminal and an output terminal. The input terminal of the power supply module 1 is connected to an AC power supply, and the output terminal of the power supply module 1 outputs a DC power supply. The control module 2 includes an input terminal and an output term...

The invention provides a dimming circuit and a lamp. The dimming circuit comprises a control module and a regulating switch, wherein the control module is used for outputting a regulating signal from an output end and comprises an input end and the output end; the input end of the control module is connected with a direct current power supply; the regulating switch is controlled by the control module and comprises a control end, an input end and an output end; the control end of the regulating switch is connected with the output end of the control module; the input end of the regulating switch is connected with an alternating current power supply; the output end of the regulating switch is connected with the lamp; and the size of current in a circuit is regulated by the regulating switch according to the intensity of the regulating signal so that the brightness of the lamp is regulated. By virtue of the dimming circuit, the brightness requirements of an actual field can be met and a waste of energy sources can be avoided.
Description
technical field [0001] The invention relates to a circuit, in particular to a dimming circuit and a lamp. Background technique [0002] Environmental protection and energy saving in today's society have become the theme of people, and how to save energy in lamps has become an important issue. If the brightness of the lamp cannot be adjusted, if the brightness of the lamp is too weak in the occasion that requires strong light, it cannot meet the requirements of the occasion; if some occasions require weak light, but the brightness of the lamp is too strong, it may cause waste of energy. Therefore, whether the brightness of the lamp can be adjusted is extremely important to life and work. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies in the prior art, and propose a dimming circuit and a lamp. Application Requirements Questions. [0004] In order to solve the above technical pr...
