Abstract

The invention relates to a lighting drive device protecting the eyesight. The device comprises a first LED light group, a second LED light group and a third LED light group, the first LED light groupis used for providing main lighting, and the second LED light group and the third LED light group assist in providing lighting and are used for providing illumination with enough strength in sequencewhen the luminance of the first LED light group cannot meet the preset requirement; a first luminous flux sensor is connected to the first LED light group and used for measuring the luminous flux of the first LED light group in real time and feeding the luminous flux back to a control unit; a first current adjusting circuit is used for controlling the luminous flux of the first LED light group under the control of the control unit, and the luminous flux is within the preset range. Accordingly, compared with the mode that adjusting is conducted through the single circuit and the single LED light groups, according to the adjusting mode, the range of an adjusted luminous flux value is larger, the two processes of rough adjustment and precise adjustment can be achieved particularly, multiple constant luminous flux values can be set, and then the processes are implemented through adjustment of multilevel circuits.

Description

technical field [0001] The invention relates to the technical field of lighting devices, in particular to a lighting driving device for protecting eyesight. Background technique [0002] At present, light-emitting diodes (LEDs) are gradually being used in road lighting, office lighting, home lighting, industrial lighting, agricultural lighting and other fields due to their long life, low power consumption, high luminous efficiency, easy control and environmental protection. People use LED's good emission wavelength monochromaticity, by combining LED chips with different emission wavelengths and / or LED chips with the same emission wavelength but using LED packages with different phosphor materials (corresponding to different output spectra) to obtain different LED light sources that output wavelength combinations / spectrums (hereinafter referred to as "combined light sources"). In the field of general lighting, because the human eye is sensitive to the deviation of color temp...
