As a preferable mode, the invention eliminates the difference of natural light received by different areas by collecting illumination brightness of different areas and adjusting the distance between the full spectrum LED lamp and the illuminated object, and adjusts the light emitted from the front surface and the light emitted from the surface to be illuminated by adjusting the angles of all the full spectrum LED lamp bands in the full spectrum LED lamp relative to the front surface and the back surface of the full spectrum LED lamp, thereby adjusting the uniformity of light in the environment, improving the lighting effect and being beneficial to the health of eyes of people.
In a specific embodiment, in a ladder classroom or a multimedia classroom, the indoor natural light distribution is obvious, meanwhile, because the object to be irradiated is not on the same horizontal plane, a traditional panel lamp installation mode is adopted, because each panel lamp cannot be adjusted in the later period after the installation is finished, at least one panel lamp can be turned on/off, and the brightness uniformity of each area in the classroom cannot be realized.
Furthermore, as the distance between the full-spectrum LED lamp and the irradiated object is reduced, the light directly irradiated to the surface of the irradiated object from the front side of the full-spectrum LED lamp is increased, which is unfavorable for the health of eyes, when the distance is reduced, the quantity of the light transmitted from the front side of the full-spectrum LED lamp is reduced and/or the energy of the light is reduced by adjusting the light emitting angle and the voltage parameter of each full-spectrum LED lamp belt in the full-spectrum LED lamp, and meanwhile, the quantity of the light transmitted from the front side of the full-spectrum LED lamp is increased and/or the energy of the light is increased, and the light reaching the surface of the irradiated object is increased in an indirect way, so that the ambient light is uniform, and the eye health is favored.
It should be noted that: the different brightness areas are not limited to the same horizontal plane and different positions, and can be different levels and different areas in a ladder classroom.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
