Unflickering LED MR16 spot light with light regulating function

Abstract

The invention relates to an unflickering LED MR16 spot light with the light regulating function, which comprises a power module, wherein the power module is arranged in the LED MR16 lamp body, can receive the controlled silicon light regulation mode, and comprises a first flickering prevention circuit, a rectifier circuit, a second flickering prevention circuit, an LED constant current source, a LED light source, a light regulation signal output circuit and a light regulation signal detection circuit, the input light regulation voltage realizes the unflickering effect through being processed by the first flickering prevention circuit, the rectifier circuit and the second flickering prevention circuit, the light regulation voltage detected by the light regulation signal detection circuit is sent to the light regulation signal output circuit to be processed, light regulation control signals are output to the LED constant current source, and the LED constant current source controls the LED light source to realize the light regulation effect. The invention is required to have wide application prospects in the aspect of LED illumination under the controlled silicon light regulation mode.

Description

Technical field [0001] The present invention relates to an LED MR16 spotlight, more specifically, to a non-flickering LED MR16 spotlight with dimming function. Background technique [0002] In traditional lighting, the halogen MR16 spotlight has a good color temperature, low voltage (12VAC) power supply and because of its good thermal resistance, it is an inductive load, making its dimming effect very perfect, so it has been used in the lighting field for a long time promotional application. However, with the development of science and technology, LED lighting with the characteristics of long life, energy saving, and no ultraviolet radiation has begun to replace traditional lighting. Halogen MR16 spotlights have begun to be replaced by LED MR16 with less power consumption due to their high power consumption. But because LED is a semiconductor device, it is driven by constant current, it is a capacitive load, and its thermal resistance is very small, so the LED MR16 on the ...

Problems solved by technology

But because LED is a semiconductor device, it is driven by constant current, it is a capacitive load, and its thermal resistance is very small, so the LED MR16 on the market cannot realize dimming like the traditional halogen MR16 spotlight; in order to be compatible with the traditional drive power MR16 Supporting equipment - electronic transformer, no matter it is halogen MR16 spotlight or LED MR16 spotlight, it is driven by 20W ~ 50W electronic transformer

However, the power of LEDMR16 is very small (generally less than 7W), while the traditional halogen MR16 spotlight is between 20W and 50W. Even if LED MR16 has no dimming function, because its power is too small, when it is connected to an electronic transformer, it will Strobe appears, not to mention dimming effect
