In a specific embodiment, in a stairway or multimedia classroom, the distribution of indoor natural light is uneven and obvious, and because the illuminated objects are not on the same horizontal plane, the traditional flat lamp installation mode is adopted, because each flat lamp cannot be adjusted in the later period after being installed, and at the same time, at least one flat lamp can only be turned on/off, and the uniform brightness of each area in the classroom cannot be realized, the sensors capable of collecting the brightness in the classroom environment, the brightness in the full-spectrum LED lamp and the brightness in the outgoing light position of the full-spectrum LED lamp are arranged in each full-spectrum LED lamp, so that the brightness of each area in each stairway is obtained, when the brightness of a certain area does not meet the requirement, the installation height of the full-spectrum LED lamp and/or the light emitting parameters of the full-spectrum LED lamp strip can be adjusted, as the brightness of the environment close to the window in the horizontal plane area is larger than the area far away from the window, the window area is marked as an area I, the area far away from the window area is marked as an area II, if the initial light-emitting parameters of the area I and the area II are the same, when the brightness of the surface of an irradiated object in the area I meets the requirement, the distance from the full-spectrum LED lamp to the irradiation surface can be gradually adjusted through the first brightness, the second brightness and the third brightness, along with the reduction of the distance between the full-spectrum LED lamp and the irradiated object, the light rays directly irradiated to the surface of the irradiated object from the front of the full-spectrum LED lamp can be increased, the energy loss of the part of light rays is small, the energy and the quantity of the light rays indirectly irradiated to the surface of the irradiated object from the back of the full-spectrum LED lamp can be reduced, and therefore the brightness of the surface of the irradiated object meets the requirement.
Furthermore, because the distance between the full-spectrum LED lamp and the irradiated object is reduced, the light rays directly irradiated to the surface of the irradiated object from the front side of the full-spectrum LED lamp can be increased to be not beneficial to the health of eyes, therefore, when the distance is reduced, the quantity of the light rays transmitted from the front side of the full-spectrum LED lamp is reduced and/or the light ray energy is reduced by adjusting the light emitting angle and the voltage parameter of each full-spectrum LED lamp strip in the full-spectrum LED lamp, meanwhile, the quantity of the light rays transmitted from the surface of the full-spectrum LED lamp is increased and/or the light ray energy is increased, the light reaching the surface of the irradiated object is increased in an indirect mode, the ambient light is uniform, and the eye health is facilitated.
It should be noted that: the different luminance areas are not limited to the different luminance areas at the same horizontal plane, and may be luminance differences at different horizontal planes and different areas in a staircase classroom.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
