Description

Technical Field

[0001] This invention relates to the field of mechanical engineering technology, and in particular to a photoelectric separation safety lighting line and lighting system. Background Technology

[0002] Traditional lighting systems generally suffer from the following problems: Electrical safety hazards: The light source and lamps of existing lighting equipment are usually directly connected to the power supply, which makes the lighting end live and poses a risk of electric shock, leakage and even fire. Especially in dangerous environments such as swimming pools, gas stations and mines, short circuits or leakage in electrical circuits may cause serious safety accidents.

[0003] Complex structure and difficult maintenance: Traditional lighting fixtures require large heat sinks to handle the heat generated by the light source, resulting in large size and weight of the fixture, high installation and maintenance costs, and a risk of falling. In addition, the electrical wiring is complex, the construction period is long, and subsequent maintenance requires frequent power outages, leading to low efficiency.

[0004] Poor environmental adaptability: Traditional lighting fixtures are difficult to meet the needs of special scenarios (such as underwater, high temperature, and corrosive environments). For example, pool lights are prone to short circuits due to water vapor intrusion, and mining lights require explosion-proof design, but existing solutions still have safety hazards.

[0005] Limited functionality: Most existing lighting systems are monochrome and always-on modes, lacking dynamic dimming or full-color lighting capabilities, and cannot meet the needs of plaza ambient lighting and personalized scenes. Summary of the Invention

[0006] In view of the above, it is necessary to provide a photoelectric separation safety lighting line and lighting system.

[0007] This invention provides a photoelectric separation safety lighting line and lighting system, comprising: Powered light-emitting host, used to connect to an external power source and generate illumination light; At least one passive light-emitting terminal is installed in the application area; A light energy transmission device, the input end of which is optically connected to the light output end of the power supply light-emitting host, and the output end of which is optically connected to the passive light-emitting terminal, is used to transmit the illumination light from the power supply light-emitting host to the passive light-emitting terminal. The passive light-emitting terminal has no electrical connection with the power supply light-emitting host and the external power source.

[0008] In one possible implementation, the optical energy transmission device includes a light-guiding optical fiber.

[0009] In one possible implementation, the power supply and light-emitting host includes a control module and a light-emitting unit. The control module is configured to control the light emission parameters of the illumination light emitted by the light-emitting unit and to communicate with at least one other power supply and light-emitting host to achieve synchronous control among multiple hosts.

[0010] In one possible implementation, the control module receives an external signal to control the illumination emitted by the light-emitting unit to be either a monochrome constant-on mode or an RGBW full-color dynamic change mode.

[0011] In one possible implementation, the passive light-emitting terminal has a non-fixed form customized according to the application scenario; the application scenario includes hazardous environments or ordinary lighting environments.

[0012] In one possible implementation, the hazardous environment is a swimming pool, a mine shaft, or a gas station; the passive light-emitting terminal is a corresponding underground light, pool light, mining light, or gas station light, and its material is a corrosion-resistant material.

[0013] In one possible implementation, the corrosion-resistant material is stainless steel.

[0014] In one possible implementation, the signal communication is a synchronization signal based on a wired or wireless communication protocol, used to control the illumination light output by multiple power-powered light-emitting hosts to remain synchronized in terms of color, brightness, or dynamic effects.

[0015] This invention also protects a photoelectric separation safety lighting line for use in a photoelectric separation safety lighting system, comprising: Optical energy transmission device; At least one passive light-emitting terminal, the input end of which is integrated with the output end of the light energy transmission device.

[0016] In one possible implementation, the optical energy transmission device is a light-guiding optical fiber, which is covered with a protective sheath.

[0017] 1. In the aforementioned photoelectric separation safety lighting line and system, electrical energy is converted into light energy by a power-powered light-emitting host and then transmitted to a passive light-emitting terminal via optical fiber. The terminal has no electrical components, completely eliminating the risk of electric shock or leakage. Optical fiber transmission involves no current flow and generates no heat source, preventing overheating that could lead to fire or explosion, making it suitable for flammable and explosive environments. The passive light-emitting terminal is made of stainless steel and has a fully sealed structure, preventing moisture and dust intrusion, making it suitable for complex environments such as swimming pools, underground installations, and underwater installations.

[0018] 2. The optical fiber loss rate in this invention is ≤0.2 dB / km, enabling long-distance optical energy transmission, reducing the need for repeater equipment, and lowering energy consumption. The passive light-emitting terminal requires no heat sink, resulting in a lightweight lamp structure and a lifespan extended to over 20 years. Maintenance only requires replacing the optical fiber or adjusting optical components, without power interruption, reducing maintenance costs by 50% compared to traditional systems.

[0019] 3. This invention, through its passive light-emitting terminal, can be designed into any form, such as in-ground lights, pool lights, mining lights, and commercial lighting fixtures, adapting to both hazardous environments and general lighting needs. It supports a single-color constant-on mode or an RGBW full-color dynamic mode, and achieves intelligent dimming by receiving external signals through a control module. Multiple powered light-emitting hosts synchronously output parameters via wired / wireless communication protocols, ensuring consistent color and brightness in large-area lighting, suitable for scenarios such as plazas and tunnels.

[0020] 4. The optical fiber in this invention has a small diameter and is flexible and bendable, making it easy to deploy in narrow spaces and shortening the construction cycle by more than 30%. The optical energy transmission device and the passive light-emitting terminal are integrated into one unit, reducing on-site assembly steps and improving installation efficiency by 50%.

[0021] 5. In this invention, no current flows through the optical fiber, avoiding the impact of electromagnetic radiation on surrounding equipment. It eliminates the need for frequent replacement of electrical components, extends the lifespan of the lamps, reduces electronic waste, and aligns with the trend of green lighting development.

[0024] Explanation of key component symbols: 1. External power supply; 2. Power supply for light-emitting host; 3. Light energy transmission device; 4. Passive light-emitting terminal. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-2 This embodiment provides a technical solution: a photoelectric separation safety lighting line and lighting system, comprising: The power supply and light-emitting host 2 is used to connect to the external power supply 1 and generate illumination light; At least one passive light-emitting terminal 4 is installed in the application area; The light energy transmission device 3 has its input end optically connected to the light output end of the power supply light-emitting host 2 and its output end optically connected to the passive light-emitting terminal 4, and is used to transmit the illumination light from the power supply light-emitting host 2 to the passive light-emitting terminal 4. The passive light-emitting terminal 4 has no electrical connection with the power supply light-emitting host 2 and the external power supply 1.

[0027] It should be noted that the power supply and light-emitting host 2 contains a power input module (for connecting to an external power supply 1) and a light-emitting unit, such as an LED light source or a laser.

[0028] The light-emitting unit converts electrical energy into light energy through an optical coupler and outputs it to the passive light-emitting terminal 4 through the light energy transmission device 3.

[0029] The main unit's casing is designed to be explosion-proof, and the internal circuitry is completely isolated from the external environment, allowing it to be installed in a safe environment, such as indoors.

[0030] The optical energy transmission device 3 uses a high-reflectivity optical fiber or optical guide tube. The input end is connected to the light-emitting unit of the host through an optical fiber lock, and the output end is optically connected to the reflector or diffuser of the passive light-emitting terminal 4.

[0031] The surface of the optical fiber is wrapped with a waterproof and wear-resistant protective layer, such as fluororubber, to ensure that light energy loss is minimized during transmission.

[0032] The passive light-emitting terminal 4 contains only a reflector, a diffuser, and a mounting bracket, and has no electrical components.

[0033] After the light energy is transmitted to the passive light-emitting terminal 4 through the optical fiber, it is concentrated by the reflector or homogenized by the diffuser before being output.

[0034] Among them, the passive light-emitting terminal 4 can be designed as any form such as an in-ground light, ceiling decorative light, pool light, gas station light, etc., and is suitable for dangerous environments or ordinary lighting environments such as swimming pools, mines, and gas stations.

[0035] The passive light-emitting terminal 4 has a casing made of stainless steel, such as 304 stainless steel, with an epoxy resin anti-rust coating on the surface, which is corrosion-resistant and has a long service life.

[0036] In summary, the passive light-emitting terminal 4 has no electrical connection to the power supply unit 2 and the external power source 1, completely eliminating the risk of electric shock and leakage, making it particularly suitable for hazardous environments such as swimming pools and gas stations. The system requires no heat sinks or high-heat-generating components, preventing fires or explosions caused by overheating. Fiber optic transmission replaces traditional high-voltage and low-voltage wiring, simplifying the construction process and reducing the risk of leakage, such as from pool lights. Maintenance of the passive light-emitting terminal 4 only requires replacing the fiber optic cable or adjusting the optical components; no power outage is required, reducing maintenance costs by 50% compared to traditional systems.

[0037] In some embodiments, the optical energy transmission device 3 includes a light-guiding optical fiber.

[0038] The optical fiber is made of high-purity quartz glass or polymer material, and its inner wall is coated with a high-reflectivity coating, such as aluminum or silver. Both ends of the fiber are connected to the coupler of the power supply light-emitting host 2 and the reflector of the passive light-emitting terminal 4 via fiber optic clasps, ensuring efficient light energy transmission.

[0039] Optical fiber's low-loss characteristics (loss rate ≤0.2 dB / km) enable long-distance transmission of light energy to the terminal, making it suitable for long-distance lighting scenarios such as large warehouses and tunnels. The fiber diameter can be as small as 1 mm, facilitating deployment in confined spaces such as mine tunnels and reducing installation costs. The fiber surface can be designed with a hydrophilic coating to enhance the interaction between light and water in water feature lighting, creating dynamic light and shadow effects.

[0040] Water features: such as the interior of swimming pool lights.

[0041] Optionally, the power supply and light-emitting host 2 includes a control module and a light-emitting unit. The control module is configured to control the light-emitting parameters of the illumination light emitted by the light-emitting unit and to communicate with at least one other power supply and light-emitting host 2 to achieve synchronous control between multiple hosts.

[0042] The control module integrates a microprocessor and a communication chip, supports RS485 / Wi-Fi protocols, and is used to adjust the brightness, color temperature, and dynamic effects of the light-emitting unit.

[0043] Multiple power-powered light-emitting main units 2 are interconnected through a communication bus, and the synchronous control module calibrates the output parameters of each main unit in real time to ensure the consistency of lighting in multiple areas.

[0044] Utilizing PWM or linear dimming technology, it supports monochrome constant illumination and RGBW full-color switching modes to meet diverse needs such as architectural outline lighting and festive decorations. Synchronous signal communication coordinates the light output of multiple hosts, avoiding brightness differences or flicker interference caused by independent control. The control module can receive environmental sensor signals, such as illuminance and temperature signals, and automatically adjust the luminous parameters to optimize energy consumption.

[0045] Among them, the microprocessor should preferably be the ARM Cortex-M series; the communication bus should preferably be the CAN bus.

[0046] Furthermore, the control module receives external signals to control the illumination emitted by the light-emitting unit to be either a monochrome constant-on mode or an RGBW full-color dynamic change mode.

[0047] The control module receives commands from external devices via a USB interface or wireless module to switch the light emission mode. In monochrome constant-on mode, the light-emitting unit outputs light of a fixed wavelength, such as 550 nm green light; in RGBW mode, it generates arbitrary color gamuts covering more than 90% of the CIE 1931 chromaticity diagram through the combination of four-color LEDs.

[0048] Monochrome mode is suitable for scenarios requiring high spectral stability, such as medical and industrial testing; RGBW mode can simulate natural light or create artistic lighting effects. External signal control simplifies the operation process, allowing non-professionals to quickly configure lighting schemes via a mobile application.

[0049] The wireless module primarily uses Bluetooth; external devices include PCs and mobile phones.

[0050] In some embodiments, the passive light-emitting terminal 4 is a non-fixed form customized according to the application scenario; the application scenario includes hazardous environments or ordinary lighting environments.

[0051] The hazardous environment is a swimming pool, a mine shaft, or a gas station; the passive light-emitting terminal 4 is a corresponding underground light, pool light, mining light, or gas station light, and its material is corrosion-resistant.

[0052] Furthermore, the corrosion-resistant material is stainless steel.

[0053] For general lighting environments: the terminal is designed as an embedded panel light or pendant light, and the reflector adopts a parabolic structure to maximize light efficiency.

[0054] Hazardous environment: In-ground light: The outer shell is made of 304 stainless steel, with an epoxy resin anti-rust coating on the surface, and a bottom sealing ring to prevent water leakage.

[0055] Pool lights: The light-emitting surface is encapsulated with sapphire glass, with a pressure resistance of ≥10 MPa and a salt spray corrosion resistance of ≥1000 h.

[0056] Mining lamps: The terminal has an embedded explosion-proof partition, is ATEX certified, and is suitable for Class II explosive gas environments.

[0057] In summary, customized form factors and corrosion-resistant materials such as stainless steel ensure long-term stable operation of the terminal under extreme conditions. The fully sealed structure with an IP68 protection rating isolates the internal optical interface from the external environment, preventing the intrusion of moisture and dust.

[0058] In some embodiments, the signal communication is a synchronization signal based on a wired or wireless communication protocol, used to control the illumination light output by multiple power-powered light-emitting hosts 2 to remain synchronized in terms of color, brightness, or dynamic effects.

[0059] Signal communication is based on a time synchronization protocol, such as IEEE 1588, and control signals are transmitted via wired or wireless means. The synchronization accuracy is controlled within ±1 ms to ensure that the light output of multiple powered light-emitting hosts 2 is completely consistent in color and brightness.

[0060] Synchronization signals eliminate timing discrepancies between multiple hosts, avoiding visual interference such as flicker caused by asynchrony. The communication protocol is highly compatible, supporting future expansion to lighting networks with thousands of terminals.

[0061] Among them, wired connections prioritize fiber optics; wireless connections prioritize ZigBee.

[0062] In some embodiments, a photoelectric separation safety lighting line is used in a photoelectric separation safety lighting system, comprising: Optical energy transmission device 3; At least one passive light-emitting terminal 4, the input end of which is integrated with the output end of the light energy transmission device 3.

[0063] In some embodiments, the optical energy transmission device 3 is a light-guiding optical fiber, and the light-guiding optical fiber is covered with a protective sheath.

[0064] Optical energy transmission device 3: The outer layer of the optical fiber is wrapped with a fluororubber protective sleeve that is resistant to temperatures from -20°C to 200°C, and the inner layer is a polyimide insulating layer.

[0065] Passive light-emitting terminal 4: The fiber optic end and the terminal reflector are integrated through a snap-fit ​​structure, and the reflector surface is coated with a nano anti-fouling coating such as titanium dioxide.

[0066] The protective sheath resists UV aging and mechanical abrasion, ensuring a fiber optic lifespan of ≥20 years. The integrated design reduces on-site construction steps and lowers labor costs.

[0067] Furthermore, the buried light, pool light, or mining light has a fully sealed structure, and its light-emitting surface is encapsulated by a light-transmitting material, thus isolating the internal optical interface from the external environment.

[0068] In practical applications, firstly, install the powered light-emitting host 2, connect it to an external power source 1, and fix it in a safe environment. The light-emitting unit inside the host converts electrical energy into light energy through an optical coupler. At this time, it is necessary to check the explosion-proof design of the host casing and the isolation status of the internal circuit from the external environment to ensure that there is no electrical exposure. Secondly, install the light energy transmission device 3, connecting the input end of the optical fiber to the light-emitting unit of the host through an optical fiber lock head. The surface of the optical fiber is wrapped with a waterproof and wear-resistant protective layer, and the output end is optically connected to the reflector or diffuser of the passive light-emitting terminal 4. When laying the optical fiber, sharp edges should be avoided to ensure that the transmission path is free from excessive bending that could cause light loss. Thirdly, install the passive light-emitting terminal 4. Select a customized terminal according to the application scenario, such as an in-ground light, pool light, or mining light. The terminal casing is made of stainless steel and coated with an anti-rust layer. During installation, it is necessary to ensure that its fully sealed structure isolates the internal optical interface from the external environment. For example, when installing a pool light, the pressure resistance of the sapphire glass encapsulation and the waterproof effect of the bottom sealing ring need to be checked. The fourth step is system debugging and control. The brightness, color temperature, and dynamic effects of the light-emitting units are adjusted via the control module of the power supply and light-emitting host 2. Multiple hosts achieve signal synchronization through wired or wireless communication protocols to ensure color and brightness consistency across multiple lighting areas. During debugging, it is necessary to verify that the light energy loss of fiber optic transmission is below 0.2 dB / km and test the uniformity and softness of the light emitted from the terminals. The fifth step is daily maintenance and safety checks. Regularly clean the dust from the fiber optic surface and the terminal reflectors / diffusers, check the wear of the fiber optic protective sheath and the integrity of the terminal sealing structure, especially in hazardous environments where the condition of the explosion-proof partition and corrosion-resistant coating is crucial. Maintenance does not require power interruption; only fiber replacement or optical component adjustment is needed. Simultaneously, the intelligent management function of the control module monitors environmental parameters and automatically optimizes light-emitting parameters to reduce energy consumption. Finally, in an emergency, operators can immediately disconnect the external power supply 1 and shut down the host. Utilizing the non-conductive properties of fiber optics to ensure no system leakage risk, damaged fiber optics or terminal components can be quickly replaced to restore lighting functionality.
