Abstract

The invention discloses a household lighting device capable of adjusting illumination intensity. The household lighting device capable of adjusting the illumination intensity comprises a communication module, a power module, a dimming module and a light emitting module. The power supply module comprises a rectification filter circuit and a power factor correction circuit. The power supply module carries out filtering, rectification and power factor correction on the alternating current of the commercial power and provides a stable direct current power supply for the lighting device provided by the invention. The communication module comprises an instruction input unit, a signal conversion unit and a micro-control unit. The micro-control unit processes the trigger signal and then generates a PWM signal. And the PWM signal acts on the dimming module. The dimming module comprises a signal control circuit and a switching tube circuit. And the signal control circuit is used for maintaining the current stability of the dimming module and controlling the on and off of the switching tube circuit according to the PWM signal so as to dim the household lighting device provided by the invention.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a household lighting device with adjustable light intensity. Background technique [0002] Household lighting is a kind of home lighting device. Among the existing household lighting devices, lighting equipment with a fixed light intensity still occupies the mainstream in practical applications, but with the improvement of people's quality of life, consumers gradually find that this kind of lighting products with a fixed light intensity can no longer be used. Meet people's increasing usage needs. Nowadays, when choosing home lighting, most consumers will first consider the degree of cooperation between the entire home lighting system and the interior design and the comfort level during actual use. That is to say, in addition to the appearance design of the lighting equipment, the selection and deployment of the light color and light intensity of the light source ha...
