Lamp capable of realizing stepless dimming

Abstract

The invention provides a lamp capable of realizing stepless dimming. The lamp comprises a lamp body, an LED light-emitting mechanism and a base; one end of the lamp body is rotatably connected with the LED light-emitting mechanism, and the other end of the lamp body is connected with the base; the lamp further comprises a dimming mechanism arranged on the lamp body, and the dimming mechanism is electrically connected with the LED light-emitting mechanism; the dimming mechanism comprises an insulation shell body, a dimming device internally provided with a diming circuit, a knob switch and a knob switch box; the dimming circuit is composed of a common mode noise suppression module, a rectification filtering module, a dimming power conversion module and an output filtering module which are sequentially connected; the input end of the common mode noise suppression module is electrically connected with an external power supply through the base; the output end of the output filtering moduleis electrically connected with the LED light-emitting mechanism; and the knob switch is connected with the dimming power conversion module. The lamp is simple in circuit structure, low in cost and high in power supply efficiency, so that the service life of the lamp is prolonged; and meanwhile, through the lamp, the illumination range can be adjusted, and moreover, stepless dimming can be achieved.

Description

technical field [0001] The invention relates to the technical field of illumination, and more specifically relates to a lamp capable of realizing stepless dimming. Background technique [0002] Because of its low power consumption, long service life, and low cost, LED lamps are widely used in lighting, display and other fields as a new type of lighting source in the current lighting field, such as LED lighting, LED display screens, LED lighting, etc. . LED lighting equipment can save more than 80% energy than traditional incandescent lamps, and has many advantages such as energy saving and environmental protection. [0003] Due to the particularity of the driving method of LED lighting equipment, general LED lighting equipment cannot be dimmed, which limits many application ranges of LED lighting equipment. At present, there are dimming LED lighting equipment on the market, but some control methods are too complicated and the equipment cost is high, and some control method...

Problems solved by technology

[0003] Due to the particularity of the driving method of LED lighting equipment, general LED lighting equipment cannot be dimmed, which limits many applications of LED lighting equipment

At present, there are dimming LED lighting equipment on the market, but some control methods are too complicated and the equipment cost is high, and some control methods are simple, but the electric energy cannot be fully utilized, which makes the power supply efficiency low and the loss is large, which not only wastes Electric energy, also reduce the service life of LED lighting equipment

[0004] Moreover, most of the existing dimmable LED lighting equipment realizes the brightness adjustment by setting gears, so there are only a few lighting modes to choose from, and it is impossible to choose and adjust according to the lighting requirements, which greatly restricts LED lighting.
