Embodiment 1

[0034] In this example, see Figure 1-7, a deep-sea LED lighting lamp, composed of a lamp head 1, a lamp front 2, a lamp middle 3, a lamp rear 4 and a watertight connector part 5; the shell part of the lamp front 2 and the lamp housing of the lamp rear 4 Parts are all hemispherical, the shell part of the lamp front part 2 is used as the front lamp housing 21, and the lamp housing part of the lamp rear part 4 is used as the rear lamp housing 43, and the front lamp housing 21 and the rear lamp housing 43 are sealed and connected together to form a spherical lighting The lamp spherical shell, the front lamp housing 21 and the rear lamp housing 43 form an internal chamber mainly composed of the front sealed cavity 63 and the rear driver assembly cavity. The front sealed cavity 63 is mainly located at the front of the lamp front 2, and the rear A part of the front driver assembly cavity is mainly located at the rear of the lamp front 2, and another part of the rear driver assembly ...

Embodiment 2

[0043] This embodiment is basically the same as Embodiment 1, especially in that:

[0044] In this embodiment, in the middle part 3 of the lamp, the continuous shell inner surface formed by connecting the front lamp housing 21 and the rear lamp housing 43 forms the inner wall surface of the middle part 3 of the lamp, and the circuit board of the driving circuit part 31 is in an arc-shaped curved surface, so that the driving The circuit board of the circuit part 31 is closely mounted on the inner wall of the lamp middle part 3, so that the inner wall of the lamp middle part 3 forms a thermal bridge structure between the circuit board of the driving circuit part 31 and the seawater environment medium outside the overall shell of the LED lighting lamp. The hot end surface of the heat dissipation part of the power supply assembly is also closely attached to the inner wall of the lamp middle part 3, so that the inner wall surface of the lamp middle part 3 forms the heat between the ...

Embodiment 3

[0046] This embodiment is basically the same as the previous embodiment, and the special features are:

[0047] In this embodiment, the front lamp housing 21 and the rear lamp housing 43 are tightly connected by screw fit connection fastening and sealing ring sealing. In this embodiment, the front lamp housing 21 and the rear lamp housing 43 are fastened by screw fit, which is convenient for quick disassembly and assembly, takes advantage of modular assembly, reduces the cost of assembly production and maintenance, and improves the efficiency of assembly production and maintenance.

Abstract

The invention discloses a deep-sea LED illuminating lamp to work as underwater illumination light source. A main body of the lamp is a spherical housing to enhance anti-pressing capacity; a lamp holder part is designed in a pressure-compensation way to improve pressure-durableness of a transparent lens in deep sea; phase-changing material is filled into a sealing cavity of the front part of the lamp to improve heat-radiating capacity of an LED base plate; a driving circuit of the LED lamp is a curved-surface circuit plate and tightly applied to the inner wall of a lamp shell; heat produced by the circuit can be directly transmitted to the lamp shell and external environment, so overall heat-radiating effect of the LED illuminating lamp can be enhanced; combination surfaces of parts of the LED lamp are in multi-stage sealing, so sealing effect of the LED lamp in the deep sea can be increased. The deep-sea LED illuminating lamp is mainly applied to deep-sea illumination field; and by the employments of the spherical lamp shell, the LED light source, the pressure compensation structure design and the curved-surface circuit plate structure, energy loss of an underwater device can be reduced and deep-sea LED illumination anti-pressing capacity and heat-radiating effect can be improved and service life of the device can be prolonged.

Description

technical field [0001] The invention relates to an LED illuminating lamp, in particular to an environment pressure-resistant illuminating lamp, which is applied to the field of lighting technology for deep sea research and exploration. Background technique [0002] Undersea research and exploration has always been the focus of scientific research in various countries, and deep-sea manned submersibles are an important tool for human beings to explore the mysteries of the deep sea. In the deep sea, almost no natural light can be seen, so the underwater lighting source has become an indispensable device for seabed survey equipment. The underwater lighting source developed earlier is metal halide lamps, especially metal halide mercury lamps. The working characteristic of metal halide lamps is that they cannot be lit immediately, and it takes about 5 minutes to heat up to achieve full brightness output. After a power outage, it takes 5-20 minutes to cool down the bulb before res...
