Straight sliding type stepless light modulator

Abstract

The invention relates to a direct-slide stepless dimming governor which includes: a box body, a circuit board component, a dimming movement component, a radiating structure and a push rod arranged in the box body, wherein, the circuit board component includes: a switch mechanism, a circuit and a plurality of power cords; the switch mechanism includes: a bidirectional dynamic contact, a unidirectional dynamic contact, a unidirectional static contact and a contact seat; a contact-head of the bidirectional dynamic contact is provided with a bidirectional contact, a tail end is arranged on the contact seat, the contacts of the unidirectional dynamic contact or the static contact are respectively corresponding to the contacts of the bidirectional dynamic contact; the power cords are welded on the circuit board and connected to a power supply and a load; the dimming movement component includes: a linear sliding potentiometer and a push rod cup arranged on a potentiometer handle of the linear sliding potentiometer; the potentiometer and contact seat are arranged on the circuit board, the push rod cup is arranged on the potentiometer handle, which slide between the bidirectional and unidirectional dynamic contacts. The light adjustment is realized by adjusting the resistance of the potentiometer through the push rod. The radiating structure is a radiating plate. Heating elements of the circuit board are connected to the radiating plate, which realizes the purpose of stepless dimming governor, radiating and expansion.

Description

technical field [0001] The invention relates to a dimming device, in particular to a stepless dimmer realized by a straight-sliding potentiometer. Background technique [0002] Lighting equipment emerges in an endless stream in modern society. People's pursuit of lighting devices has changed from appearance to energy-saving type, and then to health-type transition. That is to meet the needs of a conservation-minded society for energy saving. On the other hand, it also reflects the needs of users to adjust the intensity of lighting light according to different environments and lighting conditions due to individual differences; that is to say, people's demand for lighting equipment is not only It is only required to be able to turn on and off, and at the same time, it is also required to be able to continuously adjust the intensity of the lighting light to choose the best lighting state. [0003] Chinese patent 92222201 discloses a kind of stage dimming desk lamp device, and ...

AI Technical Summary

Problems solved by technology

This table lamp has four gears and can adjust three different powers, but this is far from meeting people's needs for adjusting the dimming effect of the adjuster.

In addition, the existing dimmer can only control the lighting equipment in a single line connected to it, which is not conducive to the intensive control of multiple rooms
