Description

Technical Field

[0001] This invention relates to the intersection of renewable energy and optical lighting technology, specifically a novel composite passive lighting device. Background Technology

[0002] Given the heat island effect of traditional large glass-roofed buildings in summer, such as train stations where the temperature inside the hall is extremely high during the summer, requiring many large umbrellas to be put up for waiting passengers to escape the heat, the main consideration for using glass roofs is to utilize natural sunlight and reduce energy consumption for lighting. However, the heat island effect in hot summer weather has not been taken into account. Glass roofs cause a surge in heat radiation in summer, and air conditioning energy consumption accounts for 40%-60% of the building's total energy consumption. Therefore, light guides can be installed on the roof of the building to refract sunlight into the interior, replacing direct sunlight through the glass and reducing heat radiation.

[0003] However, existing light guides have shortcomings in use. First, dust and impurities easily accumulate at the top of the light-collecting area, obstructing the light and affecting the lighting effect. Furthermore, since the light guide is located on the roof of the building, manual cleaning is laborious and unsafe, making it quite troublesome to clean. Second, existing light guides only serve to conduct sunlight, lacking lighting functionality at night or in dim environments, making them inconvenient to use. Therefore, a new type of composite passive lighting device is proposed to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a novel composite passive lighting device that solves the problems of existing light guides, such as dust and impurities easily accumulating at the top light-collecting point, affecting the lighting effect and being troublesome to clean, as well as the lack of lighting function and inconvenience in nighttime or dim environments due to their ability to only transmit sunlight.

[0020] This invention provides a novel composite passive lighting device. It has the following beneficial effects:

[0021] 1. This invention uses a dual-axis motor in the cleaning component to periodically start. One output end drives an arc-shaped brush to clean the entire surface of the dome lens, and the other output end drives a strip-shaped brush to clean the surface of the photovoltaic panel.

[0022] 2. This invention features a water storage tank installed on the roof of the building, which collects rainwater during rainy days. When the cleaning components are activated, a water pump is simultaneously started, sending water through a water delivery hose to the nozzles of the arc-shaped and strip-shaped pipes, which then spray the water onto the dome lens and photovoltaic panel surfaces, thereby improving the cleaning effect during sweeping. Only when the level switch detects that the water in the storage tank is insufficient will an external pump be controlled to pump water into the storage tank for cleaning purposes, thus making it more energy-efficient and environmentally friendly.

[0023] 3. This invention, by installing flexible photovoltaic panels on the building roof while setting up light guide tubes, converts excess solar energy into electrical energy stored in batteries during the day. When a photosensitive sensor detects that the ambient light intensity is lower than a set value, the PLC, in conjunction with the PLC, controls the LED beads in the light guide tube to start and uses the stored energy to power them. At the same time, a parabolic reflector diffuses the light source to achieve illumination at night and in dim environments. It can switch between light guiding and lighting modes according to ambient light, achieving energy saving and cost reduction, significantly reducing energy consumption, extending lifespan and reducing maintenance. The Moser lamp design greatly reduces replacement frequency and expensive maintenance costs, enabling intelligent control and scene-based management, on-demand dimming, improving lighting quality and environmental comfort, enhancing safety and emergency functions, and exhibiting excellent adaptability and flexibility.

[0024] 4. This invention activates the cylinder on the side wall of the light guide tube, pushes and pulls the slide to move it within the mounting base. When the position of the two dials changes, it drives the two dial heads to rotate, thereby causing the outer shaft and inner shaft to rotate in opposite directions, changing the state of the two fan plates. By gradually moving the two fan plates further apart, the indoor light intensity can be adjusted according to needs, and it can also play a shielding role when light is not needed, thus meeting the diverse needs of users.

[0053] A filter screen 23 is fitted onto the top of the inner wall of the water storage tank 22 to filter rainwater impurities entering the water storage tank 22 and prevent the nozzle 28 from becoming clogged. A water supply connector 30 is fixedly connected to the rear side of the water storage tank 22 so that water can be supplied from an external water source when the water storage tank 22 is not full.

[0054] Working Principle: The light guide tube 2 is installed on the sealed roof of a building, with its upper end exposed to the outdoors and its lower end extending into the indoor ceiling. The light guide tube 2 is made of a high-refractive-index acrylic material with a refractive index ≥1.49. It is filled with an aqueous solution containing bleach (concentration 0.1%-0.5%) to inhibit algae growth. Under lighting conditions, it refracts sunlight into the room, replacing direct sunlight through glass and reducing heat radiation. It is suitable for energy-saving renovations of glass-roofed buildings such as shopping malls, airports, and train stations, addressing the heat island effect of direct sunlight and the need for continuous day and night lighting. 2. A glass dome lens 3 is installed at the top to enhance the light-gathering effect. This lighting device, along with the light guide tube 2, also features a flexible photovoltaic panel 15 on the building roof. Combined with a solar controller 33 for charging and discharging, excess solar energy is converted into electrical energy and stored in a battery 34 during the day. When the photosensor 32 detects that the ambient light intensity is lower than a set value, the PLC 35 controls the LED beads 37 inside the light guide tube 2 to start and uses the stored energy to power them. Simultaneously, a parabolic reflector 36 diffuses the light source to achieve illumination at night and in dim environments. The system can adjust the lighting according to the ambient light intensity. The ambient light switching between light guiding and illumination modes makes it more convenient to use, reducing indoor temperature peaks by ≥8℃. Daytime illumination is equivalent to a 40-60W bulb, while nighttime LED lighting covers 20㎡, achieving a comprehensive energy saving rate of over 60%. Through dual innovation of "light path reconstruction + energy recycling," it overcomes the functional limitations of Moser lamps, significantly reducing building cooling load. The parabolic reflector 36 uses a nano-prism coating, improving nighttime luminous efficiency by 30%. The light guide tube 2 replaces glass, guiding visible light into the room through total internal reflection while blocking infrared heat radiation. The top dome lens 3 contains a hydrophobic coating and is tilted 30° to adapt to latitude. The light sensor 32 sets the threshold: LED beads 37 are turned off when the daytime light level is ≥500 lux. The light guide tube 2 is fixed by drilling holes in the roof and the gaps are sealed with silicone. The module coverage area is 20㎡ during the day (light guide mode) and 10㎡ at night (LED mode). This achieves energy saving and cost savings, significantly reduces energy consumption, extends lifespan and reduces maintenance. The Moser lamp type greatly reduces the replacement frequency and expensive maintenance costs, realizes intelligent control and scene-based management, dims on demand, improves lighting quality and environmental comfort, enhances safety and emergency functions, and has excellent adaptability and flexibility.

[0055] The dual-axis motor 7 in the cleaning assembly can be periodically activated. One output drive drives the eccentric rod 8 to rotate, causing the sleeve rod 10 and sector gear 11 to swing, which in turn drives the meshing spherical gear 12 to reciprocate along a semi-circular trajectory, allowing the arc-shaped brush 5 to clean the entire surface of the dome lens 3. The other output drive of the dual-axis motor 7, in conjunction with a bevel gear, drives the reciprocating screw 17 to rotate. Under the action of the thread and the guidance of the displacement port 21, the stroke block 19 can reciprocate along the axial direction of the reciprocating screw 17, thereby driving the strip brush 20 to clean the surface of the photovoltaic panel 15, thus automatically removing the residue above the light guide tube 2. The system also removes dust and impurities adhering to the surface of the photovoltaic panel 15, preventing it from blocking sunlight and affecting the lighting effect and power generation efficiency. It is easy to clean. A water storage tank 22 is installed on the roof of the building to collect rainwater on rainy days. When the cleaning component is started, the water pump 24 will be started simultaneously to send water through the water delivery hose 25 to the nozzles 28 of the arc-shaped pipe 26 and the strip-shaped pipe 27 and spray it onto the surface of the dome lens 3 and the photovoltaic panel 15 to improve the cleaning effect during sweeping. Only when the liquid level switch 29 detects that the water in the water storage tank 22 is insufficient will it control the external pump to pump water into the water storage tank 22 for cleaning, thus making it more energy-saving and environmentally friendly.

[0056] By activating the cylinder 43 on the side wall of the light guide tube 2, the slide 44 is pushed and pulled to move within the mounting base 42. When the positions of the two dials 45 change, the two dials 41 will rotate, thereby causing the outer shaft 39 and the inner shaft 40 to rotate in opposite directions, changing the state of the two fan plates 38. By gradually moving the two fan plates 38 further apart, the indoor light intensity can be adjusted according to needs, and a shielding function can be provided when light is not needed, meeting the diverse needs of users. The photosensitive sensor 32 is model TEPT5700, and the liquid level switch 29 is model BZ2401. The electrical components in this lighting device are powered by the storage battery 34.
