The invention discloses a light detection method and electronic equipment. The electronic equipment is provided with a light selection unit and a waveguide unit. The waveguide unit has a light reception end and a light output end, wherein the light reception end is provided with a beam splitting unit, and the light output end is provided with a photosensitive unit. The method comprises the following steps: obtaining current ambient light through the light selection unit, and enabling the ambient light to be projected to the beam splitting unit in a first direction; splitting the ambient light into different set single-wavelength light beams through the beam splitting unit, and enabling the different set single-wavelength light beams to enter the waveguide unit in different directions respectively through the light reception end; enabling the different set single-wavelength light beams to be reflected and transmitted in the waveguide unit in a first reflection manner through the waveguide unit; detecting light intensity of the different set single-wavelength light beams reflected through the waveguide unit and output through the light output end of the waveguide unit through the photosensitive unit; and generating spectrum of the ambient light according to the light intensity of the different set single-wavelength light beams.

Description

technical field [0001] Embodiments of the present invention relate to light processing technologies, and in particular, to a light detection method and electronic equipment. Background technique [0002] At present, the miniaturization of electronic devices such as mobile phones, tablet computers, and notebook computers is a development trend. In many applications of electronic equipment, it is necessary to detect the current ambient light in many cases. Detection is performed to better simulate the display status of specific items in the current ambient light scene. When the color temperature needs to be detected, the spectrum of light needs to be detected. [0003] At present, the detection method of spectrum generally realizes light splitting through diffraction grating and focusing lens, and performs spectral detection on the split light. Since the diffraction grating uses the diffraction angle to split the light, when detecting the split light, a certain distance is r...
