Method of detecting natural light in Led lamp and inductor thereof

Abstract

The invention provides a method of detecting natural light in a Led lamp. The method is characterized by only detecting a light intensity of a part of a spectrum wavelength range which is outside an artificial light spectrum range emitted by an LED, wherein a spectrum wavelength range of the artificial light spectrum range is 380nm-700nm; according to the light intensity of a part of the spectrum wavelength range which is outside the artificial light spectrum, representing an integral illumination intensity of the natural light; through a sensor and an amplification circuit or data conversion, the detected light intensity of the part of the spectrum wavelength range is converted into a natural light intensity. The invention also discloses an inductor of detecting the natural light in the Led lamp. In the invention, an inherent thinking limit is creatively broken through; a purpose of detecting the natural light intensity is realized through detecting invisible light which can not be emitted by a LED light source; the design is exquisite, enforcement is easy and cost is low; an integrated design can be realized; the natural light intensity can be accurately detected; and accurate control of the control to a lamp switch according to ambient brightness, continuous brightness adjustment and the like is realized.

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
