A method and sensor for detecting natural light placed in an LED lamp

Abstract

The invention provides a method for detecting natural light in an Led lamp, which is characterized in that only the light intensity of a part of the spectral wavelength range other than the artificial light spectral range emitted by the LED is detected, and the spectral wavelength range of the artificial spectral range is 380nm to 700nm According to the detected light intensity in part of the wavelength range other than the artificial spectrum to characterize the overall light intensity of natural light, the detected light intensity in part of the spectral wavelength range is converted into natural light intensity through sensors and amplifier circuits or data conversion. Also disclosed is a sensor placed in the LED lamp to detect natural light. The invention achieves the purpose of detecting the intensity of natural light by creatively breaking through the limitations of inherent thinking and detecting the invisible light that cannot be emitted by the LED light source. It is exquisite in design, easy to implement, and low in cost. Intensity, to achieve precise control of lamp switch control and continuous brightness adjustment according to the ambient brightness.

Description

technical field [0001] The invention relates to the field of Led lighting, in particular to a method and a sensor for detecting natural light placed in an Led lamp. Background technique [0002] With the large-scale promotion and use of intelligent lighting, existing technologies have been widely used in realizing threshold control based on light. More and more consumers hope to get a better product. When the external light reaches a certain value, the lamp can be turned off by itself, and when it is lower than the set value, it can be turned on by itself, or automatically adjust the brightness of the light according to the brightness of the surrounding light. Brightness, to achieve the interaction of artificial light and natural light, providing on-demand lighting. The light sensor built into the luminaire not only receives the light from the outside natural light, but also receives the artificial light emitted by the luminaire itself or other artificial lights around it. ...

AI Technical Summary

Problems solved by technology

The light sensor built into the luminaire not only receives the light from the outside natural light, but also receives the artificial light emitted by the luminaire itself or other artificial lights around it. Most of the time, the artificial light emitted by the LED itself or the surrounding luminaires The light intensity is far greater than the natural light intensity of the environment, so it cannot effectively and accurately detect the intensity of natural light in the surrounding environment, so it is impossible to truly realize the automatic control of the brightness and on and off of the lamps and lanterns according to the intensity of natural light; in view of this problem and the actual In order to achieve the effect of collecting only natural light, this solution is difficult to wire in actual use. , affect the appearance and use, difficult to promote in large quantities, and the cost is high
