Abstract

The invention relates to an LED lamp with a dimming function. The LED lamp comprises an LED lamp body; a dimming assembly arranged on the LED lamp body and changing the resistance value of the dimmingassembly according to the adjusting signal and / or operation; a control device arranged in the LED lamp body, electrically connected with the dimming assembly and used for detecting the resistance value of the dimming assembly and adjusting the output current according to the resistance value of the dimming assembly; and an output unit connected with the control device, receiving the output current and transmitting the output current to the LED lamp. The LED lamp has the dimming function, has no requirement for the dimming function of a chip, does not need to use a dimmer or be matched with agateway, a sensor, a remote controller and the like, and is simple in dimming function, low in cost and convenient to use.

Description

technical field [0001] The invention relates to the technical field of lamps, and more specifically relates to an LED lamp with dimming function. Background technique [0002] LED lamps on the market (such as LED tubes, LED lamp boards, etc.) cannot be connected with external dimming lines on the wiring of the lamps themselves. The existing dimming methods are mainly: 0-10V or 1-10V dimming, thyristor dimming Light, PWM dimming, etc. These dimming methods require the chip to have a dimming function. Secondly, it needs to be equipped with a corresponding dimmer or a gateway, a sensor, a remote control, etc., or an external power supply for dimming. On the one hand, these dimming methods are limited by the chip solution must have the dimming function, on the other hand, the cost is high, and it is inconvenient to use. Based on the requirements of DLC5.1 for LED lamps, the LED lamp must have the dimming function. Silicon dimming, the existing LED lamps cannot be dimmed. Cont...
