Dimming lamp

Abstract

The invention relates to dimming driving device and a dimming lamp with the dimming driving device. The dimming driving device comprises a light source drive circuit and is characterized by further comprising a Microprogrammed Control Unit (MCU) and a temporary power supply circuit, wherein the temporary power supply circuit is used for supplying electricity to the MCU after the light source drive circuit stops supplying electricity. The MCU comprises a current detection module, an analysis processing module and a storage module, wherein the current detection module is used for obtaining breakover/cutoff signals of the light source drive circuit and transmitting to the analysis processing module. The storage module is used for storing a curing program for gradual light source brightness and darkness change and status information about light source brightness constancy. The analysis processing module obtains the breakover/cutoff signals of the light source drive circuit, analyzes and processes the curing program for the gradual light source brightness and darkness change or the status information about light source brightness constancy, wherein the curing program for the gradual light source brightness and darkness change or the status information about light source brightness constancy are stored by the storage module, to generate light source brightness regulating signals, and transmits the light source brightness regulating signal to the light source drive circuit. And the light source drive circuit regulates the brightness of the light source according to control signals.

Description

[0001] This application is a divisional application of the following patents [0002] Application number: 201010179404.3 [0003] Application date: May 21, 2010 [0004] Name of invention: a dimming driving method, device and dimming lamp technical field [0005] The invention belongs to the technical field of illuminating lamp control, and relates to a dimming driving method and device and a dimming lamp with the dimming driving device. The dimming driving device controls and adjusts the brightness of a light source together with an on-off switch. Background technique [0006] In the case of increasingly tense energy sources, energy saving of lighting fixtures has become an increasingly important topic. At present, the direction of energy saving of lighting fixtures is mainly to replace traditional incandescent lamps with energy-saving lamps such as fluorescent lamps or LEDs, but there are few directions for dimming. With the development of technology, by timely adjusting...

AI Technical Summary

Problems solved by technology

Since the brightness is changed by calculating the number of ON / OFF switching of the switch, it can only adjust the brightness of the light discretely. The brightness of the light will be divided into several levels, and each different level of brightness corresponds to a different number of ON / OFF switch switching. , it cannot linearly adjust the brightness of the light at will

At the same time, when adjusting the brightness of the lamp, it is necessary to switch the switch ON / OFF frequently, resulting in the frequent on and off of the LED lamp, which is not only cumbersome, but also makes the human eyes uncomfortable, and most importantly, it will reduce the service life of the lamp.
