Lamp with functions of continuously and accurately adjusting and stabilizing light

Abstract

The invention relates to lamp with functions of continuously and accurately adjusting and stabilizing the light, automatically detecting the luminance value, displaying the luminance value and stabilizing the luminance value at the specified luminance value. The luminance value of the lamp can be set by the use manually, but if the luminance value of the lamp can not meet the requirement of the user due to other factors, the brightness of the lamp can be automatically adjusted by a circuit so that the luminance value of the lamp reverts to the specific luminance value. If the adjustment of the luminance value of the lamp fails, a warning signal can be given, and the circuit can remember the luminance value of the lamp, which is set by the use, can remember the working voltage or current of the light source and can main the working voltage or current at the specific working voltage or current and the luminance value at the specific luminance value. The lamp comprises a power supply module, an electric light source, a manually adjusting module, a displaying module, an indicating module, a controlling module and a detecting module. The detecting module is used for detecting the luminance value, the manually adjusting module is used for inputting the requirement of the user, and the controlling module is used for sending a controlling signal to the power supply module and controlling the work of the electric light source. The lamp can make the luminance meet the requirement and can save the electric energy to the maximum extent.

Description

technical field [0001] The invention relates to a lamp, in particular to a lamp with the functions of continuous and precise dimming and stable illuminance. Background technique [0002] Although the brightness of lamps on the market is adjustable, most of them are manually adjusted, and the accuracy is not high. Although some lamps have the function of stabilizing light, they cannot accurately give the illuminance, and can only ensure that the signal of the photodetector is basically stable. Accurately know the illuminance, let alone keep the illuminance at a certain value accurately. However, some domestic and foreign standards often indicate that the illuminance of certain places must meet certain requirements, such as classrooms, garages, roads, etc., and existing lamps cannot meet the requirements. Contents of the invention [0003] In order to solve the above problems, the main purpose of the present invention is to provide a lamp that can automatically detect and d...
