Light adjusting system for LED (Light Emitting Diode) lighting fixture

Abstract

The invention discloses a light adjusting system for an LED (Light Emitting Diode) lighting fixture. The light adjusting system comprises an LED lighting fixture, a control module and a traditional switch, wherein the LED lighting fixture is electrically connected inside a main circuit, the control module is arranged on the LED lighting fixture, the traditional switch is used for controlling the make-and-break of a circuit of the LED lighting fixture connected inside the main circuit; the LED lighting fixture comprises a driving power source and an LED light source, wherein the driving power source is electrically connected inside the main circuit, and the LED light source is electrically connected on the driving power source and is driven by the driving power source; a field-effect tube is arranged between the control module and the LED lighting fixture; a G pole of the field-effect tube is electrically connected with the control module; a D pole of the field-effect tube is electrically connected with the driving power source; and a S pole of the field-effect tube is electrically connected with the LED light source. The control module integrating multiple control modes is adopted in the light adjusting system and is matched with the low-loss field-effect tube to realize the light adjustment function of the LED lighting fixture; and the light adjusting system is independent of a light adjusting interface provided or not provided by the driving power source of the LED lighting fixture, is suitable for the most of LED lighting fixtures, has concise structure and high generality and is low in cost.

Description

technical field [0001] The invention relates to a dimming system of an LED lamp. Background technique [0002] Due to the characteristics of high efficiency, energy saving, and longevity, LED lamps have been widely used in various fields such as urban public lighting, office lighting, and indoor lighting. In order to further achieve the purpose of energy saving and emission reduction, especially in offices, schools, factories and other places, dimming has become an indispensable function of LED lamps. However, at present, LED lighting products on the market are uneven. Some have no dimming function, and some have dimming function, but they cannot be completely replaced with traditional dimming lamps. Rewiring is required, which increases costs and installation difficulties, and lacks universal However, it cannot meet the user's demand for simple, convenient and intelligent dimming of LED lamps.
