Problems solved by technology

[0004] However, the existing intelligent lamps adjust the color temperature of the light source of the lamp by detecting changes in the external ambient light parameters or the ambient temperature. However, when viewing the illuminated object from the perspective of the human eye, this adjustment method cannot guarantee the created environment adapted to the human eye

Abstract

The invention discloses a light detection device comprising a light receiving part and a light isolation part. The light receiving part is used for receiving light and converting the light into an electric signal. The light isolation part is used for preventing the light outside the preset range from being incident into the light receiving part on one side of the light receiving part. According tothe light detection device, the light intensity of the reflected light of the irradiated object can be detected from the human eyes, and the relative size of the reflection coefficient of the irradiated object can be identified according to the relative change of the light intensity of the reflected light of the irradiated object detected by the light detection device so that the size of the light source color temperature of the lighting device can be regulated and the lighting device is enabled to create the light environment adaptive to the human eyes. The invention also discloses the lighting device comprising the light detection device.

Description

Technical field [0001] The present invention relates to the field of lighting technology, in particular to a light detection device. The invention also relates to a lighting device. Background technique [0002] At present, the application of smart lamps is becoming more and more extensive, bringing more convenience to people's daily life and applications in various fields. At present, common smart lamps include: light intensity detection type lamps, which measure the intensity change of external ambient light through light intensity detection modules (such as photosensitive devices), and adjust the light intensity of the lighting source projected in the lighting area accordingly; color temperature detection type lamps, Use color temperature detection module (such as temperature sensor) to detect the ambient temperature, and then determine the direction of adjusting the color temperature of the lighting source; and use infrared detection module (such as pyroelectric sensor) to d...
