Furthermore, all connections / linkages mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0031] refer to Figure 1 , Figure 2 and Figure 3 The deep-sea pressure-resistant LED lamp provided by this utility model includes a housing 100, a lens 102, a front cover 101, a rear cover 202, a light source 103, and a driving power supply 201;

[0032] The housing 100 is H-shaped; the housing 100 includes a light source cavity, a power supply cavity, and a partition, with the partition disposed between the light source cavity and the power supply cavity;

[0033] The "H"-shaped design of the housing 100 plays a crucial role in several aspects of deep-sea pressure-resistant LED lighting fixtures. By dividing the housing 100 into a light source cavity and a power supply cavity, the independence of the light source 103 and the power supply is achieved, preventing mutual interference between electrical and optical components and improving the stability and safety of the lighting fixture. The compact structural design reduces the overall size of the lighting fixture, making it lighter, easier to carry, and easier to install. Furthermore, this design ensures that the housing 100 can withstand the high-pressure environment of the deep sea, guaranteeing structural stability and long-term operational capability under extreme conditions.

[0034] The light source 103 is disposed in the light source cavity, the lens 102 is disposed opposite to the light emitting surface of the light source 103, the front cover 101 is connected to the housing 100 and abuts against the lens 102 so that the lens 102 seals the light source cavity; a first sealing member is placed between the lens 102 and the housing 100.

[0035] Lens 102 transmits light emitted from light source 103, ensuring that the light can pass smoothly and illuminate the target area. The high light transmittance of lens 102 minimizes light loss and improves the lighting efficiency of the luminaire. Lens 102 covers the front of light source 103, providing physical protection, extending the lifespan of light source 103, and ensuring the long-term stable operation of the luminaire. Lens 102 can be designed in various ways (such as flat, convex, or concave) to adjust the light distribution, achieve specific lighting effects, optimize light distribution, improve the uniformity and directionality of lighting, and meet the needs of different application scenarios. Lens 102 fits tightly with the front cover 101, and a first sealing member is placed between lens 102 and housing 100, forming a sealed light source cavity. This ensures the waterproof performance of the light source cavity, prevents moisture ingress, protects internal electronic components from damage, and improves the reliability of the luminaire in deep-sea high-pressure environments.

[0036] The drive power supply 201 is located in the power supply cavity, and the rear cover 202 seals the power supply cavity; a watertight connector 203 is provided on the rear cover 202, and the watertight connector 203 is connected to the drive power supply 201.

[0037] The driver power supply 201 is housed within the power supply cavity to provide a stable current to the light source 103, thereby improving the lighting effect and lifespan of the light source 103. The rear cover 202 seals the power supply cavity, preventing moisture from the external environment from entering, ensuring the normal operation of electronic components, and improving the reliability and lifespan of the luminaire. A watertight connector 203 is provided on the rear cover 202 for connecting an external power cord, ensuring that the connection point of the power cord has good waterproof performance, preventing moisture from entering the power supply cavity through the power cord, and further improving the waterproof performance of the luminaire.

[0038] The watertight connector 203 is connected to the drive power supply 201 to ensure that the power cord can transmit power safely and reliably, guarantee the electrical connection stability of the power cord, prevent short circuits or open circuits caused by poor connection, and improve the electrical safety and reliability of the lamp.

[0039] By sealing the power supply cavity with the rear cover 202 and the watertight connector 203, the stable operation of the drive power supply 201 in the high-pressure environment of the deep sea is ensured, the reliability and safety of the lamp are improved, and the high-efficiency, stable and reliable operation of the deep-sea pressure-resistant LED lamp is ensured in extreme environments.

[0040] The light source 103 and the driving power supply 201 are connected by a wire through a small hole in the middle of the partition. The driving power supply 201 provides power to the light source 103. The partition physically isolates the light source cavity and the power supply cavity, and the small hole enables the necessary electrical connection, preventing interference between electrical and optical components. This ensures that the light source 103 can obtain the required current from the driving power supply 201 for normal operation, improving the stability and safety of the luminaire. The small hole design not only ensures the electrical connection but also minimizes the risk of moisture ingress. Furthermore, it reduces complex wiring and connecting components, making the luminaire design more compact and simple, facilitating production and maintenance.

[0041] The rear cover 202 is "E" shaped and matches the housing 100. The rear cover 202 is provided with a first groove and a second groove. A second sealing member is placed in the first groove and a third sealing member is placed in the second groove. Both the second sealing member and the third sealing member abut against the inner wall surface of the housing 100. The rear cover 202 is also provided with an internal thread that matches the external thread on the housing 100. The rear cover 202 is fixed to the housing 100 by tightening the thread.

[0042] The back cover 202 is "E" shaped and fits snugly against the housing 100, ensuring overall sealing and structural stability. The back cover 202 has two grooves, each containing a sealing component that abuts against the inner wall of the housing 100. This double-sealing design effectively improves sealing performance, prevents moisture from entering the power supply cavity, and enhances waterproofing.

[0043] The rear cover 202 has internal threads that mate with the external threads of the housing 100. Tightening the threads simplifies the installation process, reduces the complexity of additional screw fixation, and simultaneously reduces the wall thickness of the housing 100, thus lowering the weight of the luminaire. This design not only improves the reliability and safety of the luminaire but also makes it lighter, easier to carry and install, making it particularly suitable for use in high-pressure deep-sea environments. The double seal and threaded connection together ensure the efficient, stable, and reliable operation of the luminaire.

[0044] Therefore, by adopting the design of the "E"-shaped back cover 202, the combination of two grooves and two sealing components on the back cover 202, and the connection method of internal and external threads, this utility model ensures a tight fit between the back cover 202 and the housing 100. This not only improves the overall sealing performance and enhances the structural stability, but also simplifies the installation and maintenance of the lamp and reduces the weight of the lamp. This effectively prevents moisture from entering the power supply cavity and ensures the waterproof performance and reliability of the lamp in the high-pressure environment of the deep sea.

[0045] In a further embodiment of this utility model, the power supply cavity is provided with silicone potting compound, which is used for heat conduction and sealing of the drive power supply 201.

[0046] The power supply cavity is sealed with silicone potting compound to protect the driver power supply 201, ensuring complete sealing and effectively preventing the ingress of moisture and external impurities. This improves the waterproof performance and reliability of the power supply cavity. The silicone potting compound also has excellent heat dissipation properties, effectively managing internal heat and preventing damage to the driver power supply 201 due to overheating, thus extending its lifespan. Furthermore, after the silicone potting compound cures, the power supply cavity becomes a solid structure, enhancing the luminaire's resistance to pressure in the high-pressure environment of deep sea, ensuring the stable operation of the driver power supply 201. This design not only improves the overall performance of the luminaire but also simplifies the structure of the power supply cavity, reduces maintenance requirements, and ensures efficient, stable, and reliable operation of the luminaire in extreme environments.

[0047] In a further embodiment of this utility model, the housing 100, the rear cover 202, and the front cover 101 are all alloy metal components.

[0048] The housing 100, rear cover 202, and front cover 101 are all made of alloy metal, ensuring the high strength and corrosion resistance of the lamp in the high-pressure environment of the deep sea. Alloy metal materials have excellent mechanical properties, enabling them to withstand the high pressure and impact of the deep sea, ensuring the structural stability and long-term reliability of the lamp.

[0049] In a further embodiment of the present invention, the surfaces of the housing 100, the rear cover 202 and the front cover 101 are coated with an anti-corrosion material layer.

[0050] The surfaces of the housing 100, rear cover 202, and front cover 101 are coated with an anti-corrosion material layer, further enhancing the lamp's corrosion resistance, preventing seawater and salt from corroding the metal surface, and extending the lamp's service life. This design not only improves the lamp's pressure resistance and corrosion resistance in deep-sea environments but also ensures the lamp's aesthetics and durability, enabling it to operate stably for extended periods under extreme conditions.

[0051] In a further embodiment of this utility model, the driving power supply 201 includes: a rectifier bridge BD1, a constant current driving chip U1, an inductor L1, a diode D1, a transistor Q1 and a temperature control switch S1, a first filter capacitor C1, a second filter capacitor C2, a third filter capacitor C3, a fourth filter capacitor C4, a first resistor R1, a second resistor R2, a third resistor R3 and a fourth resistor R4; the light source 103 includes a light-emitting unit LED.

[0052] The rectifier bridge BD1 converts the AC input power to DC power, providing a stable DC voltage for subsequent circuits and ensuring normal circuit operation. Each filter capacitor removes ripple from the rectified DC voltage, reducing voltage fluctuations and thus providing a more stable DC voltage, thereby improving circuit stability and reliability. Each resistor limits current to prevent excessive current from damaging the chip, ensuring normal chip startup and operation.

[0053] The constant current driver chip U1 provides a constant current output, ensuring a stable current for the LED light-emitting unit, improving the brightness stability and lifespan of the LED, and preventing damage to the LED due to current fluctuations. Inductor L1, as an energy storage element, together with diode D1, forms a filter network to smooth the output current, reduce current fluctuations, improve the stability of the output current, and protect the LED. Diode D1 prevents reverse current flow, ensuring unidirectional current flow and avoiding damage to the circuit from reverse current.

[0054] The LED light-emitting unit converts electrical energy into light energy to provide illumination and is the core component of the lamp. Transistor Q1 acts as a switch, controlling the power supply to the constant current drive chip U1. Temperature control switch S1 ensures that the circuit is disconnected when the temperature exceeds a set threshold, providing over-temperature protection to prevent damage to the lamp due to overheating and improving the lamp's reliability and safety.

[0055] The input terminal of rectifier bridge BD1 is connected to the input power supply Vin, introducing AC power into the circuit. The positive output terminal of rectifier bridge BD1 is connected to the positive terminal of the first filter capacitor C1, providing a pre-filtered DC voltage. The first filter capacitor C1 and the second filter capacitor C2 are connected in parallel for further filtering, providing a more stable DC voltage.

[0056] The first end of the first resistor R1 is connected to the positive output terminal of the rectifier bridge BD1, and the second end of the first resistor R1 is connected to the VDD terminal of the constant current driver chip U1; the first resistor R1 limits the current and provides the start-up voltage for the constant current driver chip U1.

[0057] The negative output terminal of rectifier bridge BD1, the negative terminal of the first filter capacitor C1, the negative terminal of the second filter capacitor C2, and the GND terminal of constant current driver chip U1 are all grounded. The CS terminal of constant current driver chip U1 is grounded through the fourth resistor R4. The fourth filter capacitor C4 is connected in parallel with the VDD terminal and the GND terminal of constant current driver chip U1 to ensure stable operation of the circuit.

[0058] The DR terminal of the constant current driver chip U1 is connected to the first terminal of inductor L1, the second terminal of inductor L1 is connected to the anode of diode D1, the cathode of diode D1 is connected to the anode of the LED, and the cathode of the LED is grounded. The third filter capacitor C3 is connected in parallel with the LED. This part of the circuit forms a filter network, providing a stable current output to the LED.

[0059] The collector of transistor Q1 is connected to the VDD port of the constant current driver chip U1, the emitter is grounded, and the base is connected to one end of the temperature control switch S1 through the second resistor R2. The other end of the temperature control switch S1 is grounded through the third resistor R3. This part of the circuit implements over-temperature protection, disconnecting the power supply when the temperature is too high to protect the circuit and the LED unit.

[0060] The temperature control switch S1 is located inside the power supply cavity, which is filled with silicone potting compound for heat conduction and sealing of the drive power supply 201. After curing, the silicone potting compound forms a monolithic structure within the power supply cavity, improving sealing performance and effectively transferring heat from inside the cavity to the surrounding seawater through the lamp's metal casing. The lamp's heat generation primarily originates from the light source 103 and the drive power supply 201. The temperature control switch S1 continuously monitors the temperature changes of the silicone potting compound within the power supply cavity, ensuring the lamp's safe and stable operation in the deep-sea environment.

[0061] Under normal operating conditions, temperature control switch S1 is closed, and the base of transistor Q1 receives a high level through temperature control switch S1, turning on transistor Q1. At this time, the power supply provides a high level to the VDD port of constant current driver chip U1 through transistor Q1, and constant current driver chip U1 operates normally, providing a stable current to the LED, which lights up. When the lamp's operating state malfunctions, such as during water loss, the lamp's temperature rises. When the lamp's temperature exceeds the threshold temperature set by temperature control switch S1, temperature control switch S1 opens, the base of transistor Q1 loses its high level, transistor Q1 is cut off, the VDD port of constant current driver chip U1 no longer receives a high level, constant current driver chip U1 stops working, and the LED turns off. When the lamp's temperature drops below the recovery temperature threshold set by temperature control switch S1, temperature control switch S1 closes again, transistor Q1 turns on, constant current driver chip U1 resumes normal operation, and the LED lights up again.

[0062] Therefore, deep-sea lighting fixtures have good heat dissipation when used underwater, and the temperature generally does not get too high. However, if the fixture is removed from the water environment or malfunctions, the temperature may rise rapidly, leading to damage. The over-temperature protection function, through the cooperation of temperature control switch S1 and transistor Q1, promptly cuts off the power supply to prevent damage to the fixture due to high temperatures, thereby improving the reliability and safety of the fixture. In addition, temperature control switch S1 is a normally closed self-resetting temperature control switch. When the temperature drops to a safe range, temperature control switch S1 automatically resets, restoring the circuit to normal operation without manual intervention, improving the system's automation level and maintenance convenience.

[0063] By employing a constant current drive chip U1, a temperature control switch S1, and a transistor Q1, over-temperature protection for the deep-sea lighting fixture is achieved. This design ensures that the fixture automatically cuts off power in abnormally high temperatures, protecting it from damage, and automatically resumes normal operation once the temperature recovers. This not only improves the reliability and safety of the fixture but also simplifies the maintenance process and ensures long-term stable operation of the deep-sea lighting fixture in extreme environments.

[0064] In summary, deep-sea lighting fixtures are primarily designed for underwater environments and possess excellent waterproof performance. However, when the fixtures are used on the surface, heat dissipation conditions deteriorate significantly, and the temperature can rise rapidly, potentially leading to overheating and damage. Therefore, the fixtures incorporate over-temperature protection. When the temperature control switch S1 detects that the temperature exceeds a preset threshold, it automatically disconnects the circuit, cuts off the power, and extinguishes the LEDs. This effectively prevents damage from high temperatures, ensuring the fixture's reliability and safety in underwater environments. Therefore, this invention, through the combined design of the temperature control switch S1 and the transistor Q1, allows users to operate the fixture only underwater, avoiding prolonged operation on the surface, thereby extending the fixture's lifespan.

[0065] In a further embodiment of this utility model, the first sealing member, the second sealing member, and the third sealing member are all O-rings.

[0066] The first, second, and third sealing components are all O-rings, ensuring the airtightness of the power supply cavity and the light source cavity. This effectively prevents moisture and external impurities from entering, protecting the internal electrical and optical components and extending the lifespan of the luminaire. The elastic properties of the O-rings also absorb external impacts and vibrations, improving the luminaire's impact resistance and stability. This design not only improves the luminaire's waterproof performance and reliability in deep-sea high-pressure environments but also ensures the cleanliness of the light source cavity and power supply cavity, maintaining the light output effect and lighting efficiency of the light source 103, while protecting the safety and reliability of the electrical components within the power supply cavity. The uniform pressure distribution of the O-rings further enhances the sealing effect, preventing seal failure caused by uneven local pressure and ensuring the long-term stable operation of the luminaire.

[0067] In a further embodiment of this utility model, the housing 100 is an integrally formed component.

[0068] The housing 100 is a one-piece molded component, effectively improving the overall structural strength of the luminaire and enabling it to better withstand the high-pressure environment of the deep sea. This design reduces the number of seams in the housing 100, lowering the risk of leakage and further enhancing the luminaire's sealing and reliability. The one-piece molded housing 100 also simplifies the manufacturing process, reduces assembly steps, and lowers production costs. Simultaneously, this design makes the luminaire more compact and lightweight, facilitating carrying and installation, making it particularly suitable for use in deep-sea environments. By improving structural strength and sealing, the one-piece molded housing 100 ensures the stability and reliability of the luminaire under extreme conditions, extending its service life.

[0069] In a further embodiment of this utility model, the watertight connector 203 is fixed to the rear cover 202 by threads.

[0070] The watertight connector 203 is secured to the rear cover 202 with threads, ensuring the sealing and stability of the power cord connection. This design effectively prevents moisture from entering the power supply cavity through the power cord, further improving the luminaire's waterproof performance and ensuring reliability and safety in deep-sea high-pressure environments. The threaded connection simplifies the installation and disassembly process, reducing the complexity of requiring additional screws in traditional methods, making maintenance and repair more convenient and faster. Through threaded fixation, the watertight connector 203 fits tightly against the rear cover 202, ensuring a stable electrical connection and preventing short circuits or open circuits caused by poor connections, thus improving the electrical safety and reliability of the luminaire. This design not only enhances the overall performance of the luminaire but also extends its service life.

[0071] In a further embodiment of this utility model, the light-emitting unit is a COB light source, and the constant current driving chip is model LN2556.

[0072] COB (Chip-on-Board) light sources are characterized by high luminous efficacy and high brightness, making them ideal for the high-illuminance requirements of deep-sea environments. COB light sources integrate multiple LED chips directly onto a single substrate, forming an integrated light source module (103). This design not only improves the uniformity and brightness of light output but also simplifies the internal structure of the luminaire, enhancing its reliability and stability. The high luminous efficacy of COB light sources means they can provide higher light output at the same power, saving energy and extending the luminaire's lifespan. Furthermore, the integrated design of COB light sources reduces the number of components, lowers the failure rate, and facilitates maintenance and replacement. This design ensures the efficient, stable, and reliable operation of deep-sea pressure-resistant LED luminaires in extreme environments.

[0073] The LN2556 was chosen as the constant current driver chip primarily due to its high reliability, wide input voltage range, low power consumption, and built-in protection features. The LN2556 provides a stable current output to the light-emitting unit, ensuring stable brightness under various operating conditions and extending the lifespan of the light-emitting unit. Its wide input voltage range and low power consumption make it adaptable to different power conditions in deep-sea environments, improving energy efficiency. Built-in overcurrent, overheat, and short-circuit protection effectively prevents damage to the light-emitting unit, improving the safety and reliability of the luminaire. Furthermore, the LN2556's package and pin layout design facilitates integration, simplifying circuit design and manufacturing processes. In conclusion, the LN2556 plays a crucial role in deep-sea lighting, ensuring the stability and long-term reliability of the luminaire under harsh conditions such as high pressure, low temperature, and humidity.

[0074] In a further embodiment of this utility model, the lens 102 is a glass component.

[0075] First, the lens 102 should be made of reinforced special glass with high pressure resistance to ensure effective protection of the light source 103 in the high-pressure environment of the deep sea, preventing damage to the light source 103 from external pressure and thus extending the service life of the luminaire. Second, the lens 102 should preferably be made of transparent material to maximize light output, ensure light transmittance and lighting efficiency, and meet the high illumination requirements of deep-sea operations. Furthermore, the lens 102 can also use coating technology to change the color of the light, achieving specific lighting effects for different application scenarios and improving the luminaire's versatility and adaptability. Through these designs, the lens 102 not only improves the optical and protective performance of the luminaire but also ensures its reliability and safety in the high-pressure environment of the deep sea.
