Description

Technical Field

[0001] The present invention belongs to the technical field of daylighting structures, and in particular relates to a mobile sunlight reflecting daylighting system and method. Background Art

[0002] The energy of sunlight is inexhaustible, clean and safe. It is an ideal green renewable resource that is conducive to energy conservation and consumption reduction, improves environmental comfort, and promotes sustainable development.

[0003] At present, most families have rooms on the shady side that are difficult to get sunlight, and most of these rooms are bedrooms for children and the elderly. Since they cannot get sunlight all year round, the rooms become cold, damp and dim, which has a great impact on the living comfort and physical and mental health of children and the elderly. There are also some office buildings and factory areas in the shady areas or areas far away from sunlight, which rely on lights for lighting all year round and cannot see the sunlight. Compared with the staff in the rooms that can see the sunlight, the physical and mental health and enthusiasm of the staff in these rooms will be affected to a certain extent. There are also some laboratory experiments on animals and plants that require a certain amount of sunlight, but due to reasons such as the regional layout, they cannot get sunlight, which affects the experiments.

[0004] Existing solar lighting systems include light pipe systems, fiber optic systems, and fixed mirror reflection systems. The light pipe system requires drilling holes in the roof to install exposed light collectors. The overall system installation is complicated and the light energy loss at the corners of the light pipe is large. The fiber optic system is very expensive. In addition to drilling holes to lay out the exposed light collectors, fiber optic pathways need to be laid indoors and some walls need to be drilled, making fiber optic laying difficult in a home environment. The fixed mirror reflection system, in room areas in different occasions, affects the overall layout of the room area and the overall appearance and neatness of the room area because the lighting mirror system and the reflective mirror are fixed. It cannot be flexibly moved to the required work area and cannot be easily and automatically stored at any time. Summary of the Invention

[0005] The object of the present invention is to provide a mobile reflective solar lighting system and method to overcome the technical problems of existing solar lighting systems such as high cost, difficult deployment and poor flexibility.

[0006] In order to solve the above problems, the present invention adopts the following technical solutions: A mobile reflective sunlight daylighting system comprises a first mobile daylighting machine, a second mobile daylighting machine and a diffuse reflector, wherein the first mobile daylighting machine is arranged in a sunny area, and the second mobile daylighting machine and the diffuse reflector are both arranged in a shaded area; The first mobile daylighting machine and the second mobile daylighting machine respectively include a reflective mirror and a self-movable base, and the reflective mirror is installed on the self-movable base through a mirror lifting drive system; The first mobile daylighting machine, the second mobile daylighting machine and the diffuse reflector are respectively equipped with light sensors.

[0007] Furthermore, the first mobile daylighting machine is a daylighting sweeping machine, and the daylighting sweeping machine adopts a mechanism combining a mirror reflection system and a sweeping robot; The second mobile light collecting machine adopts a companion machine, which adopts a mechanism combining a mirror reflection system and a self-movable base.

[0008] Furthermore, the light-collecting sweeping machine and the companion machine are respectively equipped with cameras.

[0009] Furthermore, the diffuse reflector is arranged on the ceiling of the shaded area.

[0010] Furthermore, the diffuse reflector includes a diffuse reflection mirror surface, and a circular solar panel is provided on the periphery of the diffuse reflection mirror surface.

[0011] Furthermore, an electrified atomizing film is attached to the diffuse reflection mirror surface.

[0012] In a second aspect, a mobile reflected sunlight lighting method is provided, comprising the following steps: According to the real-time altitude and azimuth of the sun, the first mobile daylighting machine in the sunny area adjusts the base rotation angle and mirror tilt angle to complete the collection of sunlight and reflect the sunlight to the second mobile daylighting machine in the shaded area; The second mobile daylighting machine is arranged against the wall on the north side of the shaded area. Based on the position of the diffuse reflector, the base rotation angle and mirror inclination angle of the second mobile daylighting machine are determined. The second mobile daylighting machine in the shaded area receives the sunlight reflected by the first mobile daylighting machine and reflects it to the diffuse reflector to complete the sunlight daylighting.

[0013] Furthermore, the first mobile skylight adjusts the base rotation angle and the mirror tilt angle, including: When A∈(90°, 120°], β= ,β∈(45°,60°], ; When A∈[120°, 180°], β=180° -A, β∈[0°, 60°], α= ; When A∈[180°, 240°], β=180°-A, β∈[-60°, 0°], α= ; When A∈[240°,270°), β= -180°, β∈[-60°, -45°), α=90° ; Among them, A is the solar azimuth angle, H is the solar altitude angle, α is the mirror tilt angle, and β is the base rotation deflection angle.

[0014] Furthermore, based on the position of the diffuse reflector, determining the base rotation angle and mirror tilt angle of the second mobile daylighting machine includes: When the diffuse reflector is located on the ceiling in the east direction of the second mobile daylighting machine, the calculation formulas for the base rotation angle and mirror inclination angle of the second mobile daylighting machine are: =90°-

[0015] β′=135° When the diffuse reflector is located at any position in the southeast direction of the ceiling, the calculation formulas for the base rotation angle and mirror inclination angle of the second mobile daylighting machine are: =90°-

[0016] β′=90°+

[0017] When the diffuse reflector is located on the ceiling in the south direction of the second mobile daylighting machine, the calculation formulas for the base rotation angle and mirror inclination angle of the second mobile daylighting machine are: =90°-

[0018] β' =180° When the diffuse reflector is located at any position in the southwest direction of the ceiling, the calculation formulas for the base rotation angle and mirror inclination angle of the second mobile daylighting machine are: =90°-

[0019] β′=90°+

[0022] Furthermore, when the light sensor on the first mobile light-collecting machine loses the sensing signal, the first mobile light-collecting machine and the second mobile light-collecting machine retract the reflective mirrors and return to the base station for charging, and the energized atomizing film on the diffuse reflector becomes atomized.

[0023] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention provides a mobile reflective solar light lighting system, comprising a first mobile light collector arranged in a sunny area and a second mobile light collector and a diffuse reflector arranged in a shaded area. The first mobile light collector and the second mobile light collector are respectively equipped with reflecting mirrors. Through two-stage reflection (from the first mobile light collector to the second mobile light collector) in conjunction with the diffuse reflector, efficient transmission of light is ensured and uniform coverage of the shaded area is ensured, thereby solving the problem of insufficient lighting in the shaded area. At the same time, compared with existing solar light lighting systems, the "mobile" design breaks through the limitations of traditional fixed lighting systems, realizes the flexible movement of lighting equipment, and solves the technical problem of difficult arrangement.

[0024] Preferably, the mobile light collecting machine is combined with the sweeping machine, which is arranged flexibly, realizes "one machine with two uses", and improves the utilization rate of the equipment.

[0025] Preferably, a circular solar panel is provided on the periphery of the diffuse reflection mirror to power the diffuse reflector, thereby reducing dependence on the indoor power supply system.

[0026] Preferably, in the non-working state, the powered atomizing film is in an atomized state, hiding the diffuse reflection mirror and not affecting the beauty of the room; when working, it becomes transparent when powered on, ensuring that light can pass through and diffusely reflect smoothly, taking into account both functionality and aesthetics.

[0027] Preferably, the diffuse reflector is arranged on the ceiling of the shaded area, and diffuse reflection is performed from a high position so that the light covers the entire room more evenly, thereby improving the lighting range and effect without occupying ground space.

[0028] The present invention provides a mobile reflective sunlight lighting method, which uses a first mobile light collector to adjust its posture according to the angle of the sun to reflect light to a second mobile light collector. The second mobile light collector adjusts its posture based on the position of a diffuse reflector to reflect light to the diffuse reflector, thereby collecting sunlight. Through the "two-stage reflection" mechanism, the problem that sunlight is difficult to directly illuminate shaded areas is solved, and long-distance and accurate transmission of light is achieved. Through the "base station silent-mobile lighting-return to base station" working mode, that is, the mode from the base station to the working point and then from the working point back to the base station, the problems of traditional reflective mirror lighting equipment such as the inability to move intelligently and independently, occupying location space and being unable to be conveniently stored are avoided.

[0029] Preferably, the base rotation angle and mirror inclination angle of the first mobile light-collecting machine are continuously adjusted through the relationship between the posture of the first mobile light-collecting machine and the position of the sun, ensuring that the reflecting mirror of the first mobile light-collecting machine can direct sunlight horizontally parallel to the north-south direction toward the companion machine.

[0030] Preferably, for the situation where the diffuse reflector is at different positions on the ceiling, by continuously adjusting the base rotation angle and mirror inclination angle of the second mobile light collector, it is ensured that the light reflected by the second mobile light collector accurately reaches the diffuse reflector, avoiding lighting failure caused by light deviation.

[0041] The first mobile daylighting machine 2 is charged through the first mobile daylighting machine base station 1 , and the second mobile daylighting machine 2 is charged through the second mobile daylighting machine base station 5 .

[0042] In this embodiment, the automatic charging, self-propelled movement, navigation and obstacle avoidance, scheduled appointment, remote control and other functions of the light-emitting sweeping robot and the companion robot all adopt the mature technologies of existing sweeping robots on the market.

[0043] like Figure 4As shown, the diffuse reflector 4 includes a diffuse reflective mirror 401, a circular solar panel 402 is arranged on the periphery of the diffuse reflective mirror 401, a third light sensor 405 is installed on the circular solar panel 402, and an electrified atomizing film 403 is attached to the surface of the diffuse reflective mirror 401, and the electrified atomizing film 403 is controlled by a third control unit 404; The diffuse reflector 4 is located on the ceiling, and the diffuse reflection mirror surface 401 is a curved mirror surface.

There is a circle of circular solar panels 402 on the edge of the mirror surface, which is used to charge the battery of the diffuse reflector 4; there is a third light sensor 405 on the circular solar panel 402, which is used to control the electrified atomized film 403 to turn on and become transparent after being irradiated by the sunlight reflected by the companion machine.

[0044] The present invention perfectly solves the lighting problem in dark areas such as indoor shaded areas or factory buildings, avoiding the physical and mental health impacts of these rooms or areas due to the darkness and humidity all year round on family members or practitioners; for residential buildings, multi-story factories and laboratories that cannot have holes in the top to set up light pipes and set up fiber optic lighting systems outdoors and lay fiber optic pathways, the present invention provides a simple, feasible and complete lighting solution; the combination of the lighting system and the sweeping robot, and the cooperation of the companion robot, utilizes the mature walking, obstacle avoidance and charging functions of the sweeping robot, which can both light and clean, and serve two purposes in one machine; the mode of this invention from the base station to the working point and then from the working point back to the base station avoids the inability of traditional reflective mirror lighting equipment to move intelligently and independently, avoids the fixed placement in home life or other environments to occupy space, and avoids the technical problem of the inconvenient storage of traditional lighting equipment.

[0045] The present invention also provides a mobile sunlight reflection lighting method, such as Figure 6 As shown, the following steps are included: According to the real-time altitude and azimuth of the sun, the first mobile daylighting machine 2 in the sunny area adjusts the base rotation angle and the mirror tilt angle to complete the collection of sunlight and reflect the sunlight to the second mobile daylighting machine 3 in the shaded area; The second mobile daylighting machine 3 is arranged against the wall on the north side of the shaded area. Based on the position of the diffuse reflector 4, the base rotation angle and mirror inclination angle of the second mobile daylighting machine 3 are determined. The second mobile daylighting machine 3 in the shaded area receives the sunlight reflected by the first mobile daylighting machine 2 and reflects it to the diffuse reflector 4 to complete the sunlight daylighting.

[0046] The lighting process Figure 5 As shown: Specifically, the sun is irradiated with the north direction as 0° azimuth, the sun rotates clockwise as positive, the sun's altitude angle is H, and the sun's azimuth angle is A. When the skylight sweeper points its camera toward the north, the north direction is 0° deflection, the skylight sweeper rotates clockwise as positive, and the deflection angle of rotation is β; the angle between the rising reflective mirror of the skylight sweeper and the upper plane of the sweeper is α, α is 0° or a positive value. The companion machine has the north direction as 0° deflection, and the clockwise rotation is positive, and the deflection angle of rotation is β′. The angle between the rising reflective mirror and the upper plane of the companion machine is The altitude angle of the diffuse reflector is , the azimuth is ; Set up a base station in a suitable location at home (office buildings or factories, etc. can also be set up in a suitable location). Both the skylight sweeper and the companion machine have charging electrodes. When they are not working and in a silent state, they charge at the base station. When they need to work, they leave the base station and return to the base station to charge when the work is finished. When lighting is needed, the daylighting sweeper and the companion machine are both started and run away from the base station. The daylighting sweeper arrives at an area where the sun can shine, such as a balcony or a south-facing room, and the companion machine arrives at a shady room or a shaded area that needs lighting, connects to the diffuse reflector 4, and prepares for lighting operations; When the first light sensor 201 of the daylight sweeper senses sunlight, the first control system 208 calculates the mirror tilt angle α of the mirror according to the real-time solar altitude angle H and solar azimuth angle A according to an algorithm, and simultaneously issues a command to the first mirror drive system 202 to raise the first reflective mirror 201 to the tilt angle α. The first control system 208 controls the first drive wheel 209 of the reflective sweeper to rotate according to the algorithm, so that the base rotates to the deflection angle β. At this time, the sunlight shining on the reflective sweeper is reflected and then directed horizontally and parallel to the north-south direction toward the companion machine. Specifically, the first mobile daylighting machine 2 adjusts the base rotation angle and the mirror tilt angle by: When A∈(90°, 120°], β= ,β∈(45°,60°], ; When A∈[120°, 180°], β=180° -A, β∈[0°, 60°], α= ; When A∈[180°, 240°], β=180°-A, β∈[-60°, 0°], α= ; When A∈[240°,270°), β= -180°, β∈[-60°, -45°), α=90° ; Among them, A is the solar azimuth angle, H is the solar altitude angle, α is the mirror tilt angle, and β is the base rotation angle. The companion machine moves to the shaded area or area that needs lighting. In order not to affect the movement of people and optimize the room layout, the companion machine is close to the north wall of the room or area, where it can also receive all the light reflected directly from the lighting sweeper. Angle, the second driving wheel 309 and the second universal wheel 307 rotate to make the companion machine rotate β Angle, since the position of the diffuse reflector 4 is fixed, the light reflected from the light sweeping machine is reflected by the mirror of the companion machine, and the light hits the diffuse reflector 4. The base rotation angle and mirror inclination angle of the second mobile light sweeping machine 3 are determined based on the position of the diffuse reflector 4, specifically including; When the diffuse reflector 4 is located on the ceiling in the east direction of the second mobile daylighting machine 3, the calculation formulas for the base rotation angle and the mirror inclination angle of the second mobile daylighting machine 3 are respectively: =90°-

[0047] β =135° When the diffuse reflector 4 is located at any position in the southeast direction of the ceiling, the calculation formulas for the base rotation angle and the mirror inclination angle of the second mobile lighting machine 3 are: =90°-

[0048] β′=90°+

[0049] When the diffuse reflector 4 is located on the ceiling in the south direction of the second mobile daylighting machine 3, the calculation formulas for the base rotation angle and the mirror inclination angle of the second mobile daylighting machine 3 are respectively: =90°-

[0050] β =180° When the diffuse reflector 4 is located at any position in the southwest direction of the ceiling, the calculation formulas for the base rotation angle and the mirror inclination angle of the second mobile lighting machine 3 are: =90°-

[0051] β =90°+

[0052] When the diffuse reflector 4 is located on the ceiling in the west direction of the second mobile daylighting machine 3, the calculation formulas for the base rotation angle and the mirror inclination angle of the second mobile daylighting machine 3 are respectively: =90°-

[0053] β =225° in, is the azimuth angle of the diffuse reflector 4, is the altitude angle of the diffuse reflector 4, is the mirror reflection angle of the second mobile lighting machine 3, β The base rotation angle of the second mobile daylighting machine 3.

[0054] Measure the distance from the midpoint of the top surface of the companion machine to the midpoint of the 4 arc surfaces of the diffuse reflector, and then combine the net height obtained by combining the room height, the height of the top surface of the companion machine and the height of the midpoint of the 4 arc surfaces of the diffuse reflector from the roof. According to the sine theorem, the altitude angle of the diffuse reflector is Measure the vertical distance from the midpoint of the diffuse reflector's 4 arc surfaces to the northernmost wall of the room, and measure the vertical distance from the midpoint of the top surface of the companion machine to the northernmost wall of the room, and calculate the difference between them. This difference is combined with the length of the projection of the distance from the midpoint of the top surface of the companion machine to the midpoint of the diffuse reflector's 4 arc surfaces on the horizontal plane. According to the Zhengxuan theorem, the azimuth angle of the diffuse reflector is ; When the third light sensor 405 of the daylight sweeper does not sense sunlight, the daylighting operation ends. The daylight sweeper and the companion machine level off and retract the reflective mirror, self-adjust and move back to the base station for charging, and the energized atomizing film 403 of the diffuse reflector 4 turns off the signal and turns into an atomized state.

[0055] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited thereto. Within the technical concept of the present invention, various simple variations of the technical solution of the present invention may be made, including combining the various technical features in any other appropriate manner. These simple variations and combinations should also be regarded as disclosed in the present invention and fall within the scope of protection of the present invention.
