Lamp with functions of continuously and accurately adjusting and stabilizing light

Abstract

The invention relates to a lamp with functions of continuously and accurately adjusting and stabilizing the light, comprising 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 power supply module is electrically connected to the electric light source. The controlling module is electrically connected to the power supply module. The manually adjusting module is electrically connected to the controlling module. The controlling module is electrically connected to the indicating module. The detecting module is electrically connected to the controlling module. The controlling module memorizes an illuminance value set by a user, or the operation voltage or current of the light source. The user selects to maintain the light source at appointed operation voltage or current or at the appointed illuminance value. The circuit automatically detects the illuminance and displays the illuminance value, and settles the illuminance value at the appointed value. If the stable illuminance is failure, an alarm signal is sent. 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...
