[0002] With the advancement of science and technology, the exploration and resource development of the deep sea have received increasing attention. The deep sea is a high-pressure liquid environment, and natural light becomes weaker and weaker with increasing depth. Therefore, underwater lighting sources have become an indispensable tool for deep-sea exploration.

[0003] Traditional underwater lights are large and complex, often making them unsuitable for long-term stable operation and hindering deep-sea exploration activities. LED lights, as a new type of light source, have been widely used in deep-sea lighting due to their long lifespan, small size, and high luminous efficiency. However, traditional LED underwater lights lack safety and stability during operation, and can burn out due to overheating. Furthermore, the round lamp head often slips during assembly due to the lack of a fixed support surface, increasing assembly difficulty. Utility Model Content

[0022] A high-power focused LED light fixture for deep-sea applications, such as Figures 1 to 4 As shown, the device includes: a lamp head 2; an mounting straight edge 21, circumferentially disposed on the outside of the lamp head 2; a front cover 1, screwed to the top of the lamp head 2, forming an optical cavity 11 with the lamp head 2; a light source 22, mounted on the lamp head 2 and located within the optical cavity 11; a cylindrical body 3, screwed to the bottom of the lamp head 2, forming a power supply cavity 31 with the lamp head 2; a power supply assembly 32, disposed on the lower surface of the lamp head 2 and located within the power supply cavity 31; a clamping assembly 4, disposed on the outside of the cylindrical body 3; and an oil-filled layer 33, disposed within the cylindrical body 3 and located between the cylindrical body 3 and the power supply assembly 32. The power supply assembly 32 includes a control circuit that monitors the temperature of the oil-filled layer 33 and disconnects the circuit when the temperature exceeds a threshold.

[0023] The front cover 1, lamp head 2, and tail cover 6 form the outer shell of the lamp fixture, which are fixed together by threads. The remaining structures are located inside the outer shell. Two sealing rings are provided between the front cover 1 and the lamp head 2, and one sealing ring is provided between the lamp head 2 and the cylindrical body 3 to improve waterproof performance. The optical cavity 11 formed by the front cover 1 and the lamp head 2 is used to house the light-emitting components such as the light source 22. The power cavity 31 formed by the cylindrical body 3 and the lamp head 2 is used to house the power supply components 32 such as the driving power supply. Multiple openings are provided in the middle of the lamp head 2 to allow wires to be threaded through the power supply cavity 31 and the optical cavity 11 for electrical connection. Multiple symmetrical mounting straight edges 21 are provided on the outer side of the lamp head 2. The power supply components 32 include the driving power supply and the control circuit, which are electrically connected. The remaining space of the power supply cavity 31 is filled with oil to form an oil layer 33, which is used to accelerate the heat dissipation efficiency of the power supply components 32 and improve the heat dissipation performance of the lamp fixture.

[0024] In this embodiment, the lamp head 2 is wider at the top and narrower at the bottom, and the optical cavity 11 is larger than that of a traditional LED underwater lamp, allowing it to accommodate a larger and more powerful light source 22. The bottom of the cylinder 3 is also equipped with a tail cap 6, which is threaded together with the lamp head 22.

[0025] By setting a control circuit to monitor the temperature of the oil-filled layer 33 and disconnecting the control circuit when it exceeds the threshold, safety and stability are improved; by setting the assembly straight edge 21, the lamp head 2 is easy to clamp during production assembly, preventing slippage and simplifying the assembly process.

[0026] Furthermore, such as Figure 2 and Figure 3 As shown, the clamp assembly 4 includes a first clamp 41, a second clamp 42 and a fastener 43. The first clamp 41 is circumferentially disposed on the outer wall of the cylinder 3, and the second clamp 42 is disposed on one side of the first clamp 41. Both the first clamp 41 and the second clamp 42 are provided with corresponding openings (not shown in the figure), and the fastener 43 is connected to the openings.

[0027] The first clamp 41 is used to clamp the cylinder 3, and the second clamp 42 is used to clamp the external environment, thereby achieving the installation and fixation of the lamp. The size and shape of the first clamp 41 correspond to the cylinder 3. Both the first clamp 41 and the second clamp 42 consist of two parts, which are spliced ​​together by screws or clips. The spliced ​​first clamp 41 and the second clamp 42 are connected by a fastener 43. The type of fastener 43 is not limited here, as long as it can firmly connect the two parts, such as clips and screws. The size and shape of the second clamp 42 is not limited here, and various shapes and sizes of second clamps 42 can be used, such as round, rectangular, etc., to achieve the installation and fixation of the lamp on external objects of different shapes.

[0028] In this embodiment, the second clamp 42 has the same shape and size as the first clamp 41, and the first clamp 41 and the second clamp 42 are connected by bolts.

[0029] Specifically, such as Figure 2 and Figure 3 As shown, it also includes a protective sleeve 12, which is circumferentially positioned on the outside of the front cover 1. The material of the protective sleeve 12 is not limited here, as long as it can protect the front cover 1 and possesses good durability and corrosion resistance, such as plastic or rubber. The protective sleeve 12 can be connected to the front cover 1 by screws or by relying on the elasticity of the protective sleeve 12 itself for tightening and fixation. By providing a protective sleeve 12 on the outside of the front cover 1, damage to the front cover 1 due to impact or scratches during assembly and use is prevented.

[0030] Specifically, such as Figure 4 As shown, the control circuit includes a rectifier circuit, a filter circuit, a constant current chip control circuit, and an LED working circuit. The filter circuit is connected to the rectifier circuit and the LED working circuit. The LED working circuit is connected to the constant current chip control circuit. The rectifier circuit includes a rectifier bridge BD1, which is connected to the input terminal. The filter circuit includes a first capacitor C1 and a second capacitor C2. The LED working circuit includes a third capacitor C3. The constant current chip control circuit includes a constant current driver chip U1 and a fourth capacitor C4.

[0031] It also includes a high-frequency oscillation output circuit, which connects to the LED operating circuit, constant current chip control circuit, LED filter circuit, and filter circuit. The high-frequency oscillation output circuit includes diode D1 and transformer L1. The rectifier bridge is connected to the input terminal Vin of the entire circuit to prevent the lamp from burning out due to reverse connection of the input terminal. The filter circuit is used to reduce input ripple and improve safety and reliability. The filter circuit also includes a varistor R1, which is connected between the first capacitor C1 and the second capacitor C2. The constant current chip control circuit also includes resistors R2 and RES. The constant current driver chip U1 includes GND pin, VDD pin, MODE pin, DR pin, CS pin, and three NC pins.

[0032] In this embodiment, the constant current driver chip U1 is model LN2556.

[0033] Furthermore, such as Figure 4 As shown, the control circuit also includes a temperature control component, which includes a switch S1 and an overcurrent relay. The overcurrent relay is only connected to the switch S1, which is connected in series between the rectifier line and the filter line.

[0034] The overcurrent relay is a temperature-sensitive overcurrent relay, combining temperature sensing and overcurrent protection functions. It incorporates a built-in thermistor to monitor temperature changes in the oil-filled layer 33. When the lamp is removed from the water surface while powered on or malfunctions, the temperature of the oil-filled layer 33 rises sharply due to the power supply component 32. When the temperature of the oil-filled layer 33 exceeds a threshold, the thermistor outputs a corresponding signal, causing the switch to quickly open, thus protecting the lamp from overheating damage. When the temperature of the oil-filled layer 33 drops to a safe value, the switch automatically returns to the closed state. By setting a temperature control switch S1 to monitor the temperature of the oil-filled layer 33, over-temperature protection for the lamp is achieved without additional mechanical structures, making the implementation simple, safe, and relatively low-cost.

[0035] Specifically, such as Figure 2 and Figure 3 As shown, a reflector cup 23 is mounted on the light source 22. The reflector cup 23 is located inside the optical cavity 11 and is wider at the top and narrower at the bottom. It is used to reduce the beam angle of the light emitted from the light source 22, thus acting as a focusing agent. The material of the reflector cup 23 is not limited here; it only needs to be able to operate normally in a deep-sea environment, such as a metal or alloy material with good pressure resistance, heat dissipation, and corrosion resistance. Furthermore, such as Figure 2 and Figure 3 As shown, the bottom of the reflector cup 23 is provided with a reflector cup bracket 24, which is located between the reflector cup 23 and the light source 22. The reflector cup bracket 24 fixes the reflector cup 23 and the light source 22 to the lamp head 2 from top to bottom by mounting screws. The close contact between the light source 22 and the lamp head 2 can improve heat dissipation performance, and the close contact between the reflector cup 23 and the light source 22 can improve light utilization and focusing effect.

[0036] Specifically, such as Figure 2 and Figure 3 As shown, an oil bladder assembly 5 is also provided inside the cylinder 3. The oil bladder assembly 5 is pressed and fixed in the cylinder 3 by the bottom of the cylinder 3 and is located between the bottom of the cylinder 3 and the power supply assembly 32. The oil bladder assembly 5 is used to achieve pressure compensation, and the expansion and contraction of the oil bladder 51 balances the air pressure of the power supply chamber 31 and the seawater.

[0037] Furthermore, such as Figure 2 and Figure 3 As shown, the oil bladder assembly 5 includes an oil bladder 51, an oil bladder retaining ring 52, and an oil bladder buckle 53. The oil bladder buckle 53 fixes the oil bladder 51 onto the oil bladder retaining ring 52 to form a compression seal.

[0038] The oil bladder assembly 5 includes an oil bladder 51, an oil bladder retaining ring 52, an oil bladder clip 53, and an oil bladder gasket 54. The tail cap 6 is threadedly connected to the cylinder body 3, pressing and fixing the oil bladder 51 and the oil bladder gasket 54 inside the cylinder body 3. The oil bladder clip 53 is locked with screws, thereby securing the bladder nozzle (not shown in the figure) of the oil bladder 51 inside the oil bladder retaining ring 52, forming a compression seal.

[0039] Specifically, such as Figure 2 and Figure 3 As shown, the lamp holder 2 also includes a light-transmitting sheet 25, which is connected to the top of the lamp holder 2. When the front cover 1 is threadedly connected to the lamp holder 2, the light-transmitting sheet 25 is pressed and fixed onto the lamp holder 2.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
