Description
Technical Field
[0001] The utility model relates to the technical field of lamps, and more specifically, to a marine searchlight. Background Art
[0002] At present, the main light sources of marine searchlights are metal halide lamps and xenon lamps, which occupy most of the market share. Because the light-emitting area of the metal halide lamp is large, it is difficult to achieve a good light-concentrating effect through the optical structure, so it is impossible to achieve long-distance searchlighting. The disadvantage of the xenon lamp is that the light source life is very short, usually only a few hundred hours, and the xenon lamp will generate an ultra-high instantaneous voltage at the moment of lighting, and its product safety and reliability are very poor.
[0003] The LED light source has the advantages of long light source life and stable quality, but it has relatively high requirements for heat dissipation. However, marine searchlights need to have a certain corrosion resistance, and usually stainless steel is used as the housing. However, stainless steel has poor heat dissipation performance. If the LED is used as the light source, the heat dissipation problem of the LED light source is a very important technical problem, because the LED light source has high requirements for heat dissipation, but stainless steel has poor heat dissipation performance. In addition, the working environment of marine searchlights makes them very easy to come into contact with water. Therefore, more rigorous measures are needed to prevent the LED light source from coming into contact with water, such as by adopting a sealed and waterproof lamp barrel structure design. However, good sealing and waterproofing are often in conflict with good heat dissipation. Therefore, the internal structure of the lamp barrel of the marine searchlight is very complex, which inevitably makes the lamp barrel bulky and the manufacturing cost high.
[0004] The market urgently needs a marine searchlight with an LED light source and a stainless steel housing, which can well solve the heat dissipation problem of the LED light source on the premise of ensuring high brightness and long searchlighting distance, so as to ensure the stable and reliable quality of the product. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a marine searchlight with an LED light source and a stainless steel housing, which has good heat dissipation performance, corrosion resistance, waterproof performance and light beam concentrating performance, and is simple in structure, convenient to use and relatively low in cost.
[0006] The purpose of the utility model is achieved as follows:
[0007] A marine searchlight includes a searchlight main body, and the searchlight main body includes: an LED integrated light source, a driving power supply, an optical lens, a radiator and a stainless steel lamp barrel. The radiator is fixed in the stainless steel lamp barrel, and the LED integrated light source is fixed on the substrate of the radiator.
[0008] The radiator is an aluminum radiator, including: a substrate and heat dissipation fins, and the substrate and the heat dissipation fins are integrally manufactured by a cold forging and forming process in one time.
[0009] For the stainless steel lamp cylinder, with the light emission direction as the front, it includes: a stainless steel fixing ring, a stainless steel front lamp cylinder, a stainless steel rear lamp cylinder and a stainless steel rear cover plate. An installation hole is provided on the rear end face of the stainless steel front lamp cylinder. The substrate of the radiator is fixed at the rear end of the stainless steel front lamp cylinder. At the same time, the heat dissipation fins of the radiator pass through the installation hole and are arranged outside the stainless steel front lamp cylinder. The stainless steel rear lamp cylinder is sleeved outside the heat dissipation fins, and the front end face of the stainless steel rear lamp cylinder is connected and fixed to the rear end face of the stainless steel front lamp cylinder. The rear cover plate is detachably fixed at the rear end of the stainless steel rear lamp cylinder. The stainless steel fixing ring is detachably sleeved on the front end of the stainless steel front lamp cylinder. A plurality of heat dissipation holes are provided on the barrel wall of the stainless steel rear lamp cylinder and on the rear cover plate.
[0010] The optical lens includes: a combined lens and a condenser lens. The combined lens is fixed on the substrate of the radiator and is arranged in front of the light emission direction of the LED integrated light source. The condenser lens is a Fresnel lens, and the Fresnel lens is arranged in the stainless steel front lamp cylinder and is close to the front end of the stainless steel front lamp cylinder. The combined lens is an optical device formed by fixing and combining two or more optical glass lenses together through a specific mechanical structure for integrated use, and can be directly purchased on the market according to design requirements.
[0011] For the marine searchlight proposed by the present utility model, due to the adoption of the above technical solution, compared with the prior art, it has the following beneficial effects: The marine searchlight proposed by the present utility model adopts a brand-new lamp cylinder structure. The heat dissipation fins of the radiator and the LED integrated light source are respectively arranged in the stainless steel rear lamp cylinder and the stainless steel front lamp cylinder, and the stainless steel rear lamp cylinder and the stainless steel front lamp cylinder are separated by the cooperation of the radiator substrate and the installation hole to form two relatively independent spaces. The barrel body and the rear cover plate of the stainless steel rear lamp cylinder for accommodating the heat dissipation fins are provided with enough heat dissipation holes to provide excellent heat dissipation performance. The stainless steel front lamp cylinder for accommodating the LED integrated light source provides sealed and waterproof protection for the LED integrated light source. The overall structure is simple, which not only realizes the heat dissipation requirement of the radiator, but also meets the sealing requirement of the LED light source part, and reduces the cost. In addition, for the marine searchlight proposed by the present utility model, the optical structure of the LED integrated light source, the combined lens and the condenser lens is adopted, and relatively small light source power can be used to obtain relatively high brightness and relatively long searchlight distance, and the heat generation is smaller while providing the same brightness, which indirectly overcomes the adverse effect of the stainless steel shell on the heat dissipation of the LED light source and achieves the purpose of ensuring product quality.
[0012] Among them, the barrel wall of the stainless-steel front lamp barrel bulges outward at the front end, thereby forming a barrel wall step on the inner wall, and the Fresnel lens is clamped on the barrel wall step and thus fixed near the front end of the stainless-steel front lamp barrel.
[0013] Preferably, the marine searchlight further includes a toughened glass, which is stacked outside the Fresnel lens. A waterproof gasket is nested on the outer edge of the toughened glass to further enhance the waterproof performance of the marine searchlight. The stainless-steel fixing ring is sleeved on the edge of the front-end port of the stainless-steel front lamp barrel to lock and fix the Fresnel lens and the toughened glass nested with the waterproof gasket in the front-end port of the stainless-steel front lamp barrel.
[0014] Preferably, the edge of the front-end port of the stainless-steel front lamp barrel is provided with a flanging, and the stainless-steel fixing ring is sleeved on the flanging, so that the fixing effect of the stainless-steel fixing ring can be better realized, and the waterproof sealing performance of the marine searchlight is further enhanced.
[0015] Among them, a waterproof silicone rubber is coated on the contact surface between the stainless-steel front lamp barrel and the substrate of the radiator, thereby further enhancing the overall waterproof performance of the lamp.
[0016] Among them, the thickness of the Fresnel lens is 1-5 mm, and the diameter is 100-700 mm; the luminous diameter of the luminous surface of the combined lens is 10-100 mm. Selecting lenses within this range can further enhance the beam condensation effect of the LED integrated light source of the searchlight. The luminous surface of the combined lens refers to the area of the outermost surface of the combined lens that is exposed, that is, the surface where the light rays of the LED light source are refracted by the combined lens and then emitted.
[0017] Among them, the drive power supply is fixed to the rear end of the radiator through a stainless-steel plate.
[0018] Furthermore, in order to facilitate the fixing or installation of the marine searchlight during use, the marine searchlight as described above can also be provided with a support device for providing support to the searchlight body so that the marine searchlight can be placed at the installation location.
[0019] As an achievable method, the support device may include: a support member and two stainless steel fixing blocks for connecting the support member to the searchlight body of the marine searchlight. Specifically, support member mounting holes are provided on both sides of the stainless steel rear lamp tube, and fixing substrates are arranged on both sides of the radiator at positions corresponding to the support member mounting holes. The fixing substrate, the base plate, and the heat dissipation fins are manufactured as a whole through a cold forging one-step forming process, and the two stainless steel fixing blocks are respectively fixed on the fixing substrate on the same side; the support member includes two supporting arms, and the two supporting arms are rotatably connected to the two stainless steel fixing blocks, respectively, so that the searchlight body can rotate around the connecting axis between the supporting arm and the stainless steel fixing block under the action of external force. The specific connection mode between the support arm and the stainless steel fixing block can be realized by any existing structure, such as a hinge structure, a pin structure, a bolt structure, etc., or even simply by not completely tightening the screws, as long as the support arm and the stainless steel fixing block can rotate relative to each other around the connecting axis under the action of external force (for example, by pulling with hands), that is, the searchlight body can rotate around the connecting axis. In this way, the searchlight body can adjust the irradiation direction as needed. Of course, if it is completely fixed, the direction can be adjusted by loosening the fasteners (for example, loosening the completely tightened screws), which is more suitable for the situation where the irradiation direction is relatively fixed.
[0020] The marine searchlight provided by the utility model is manufactured as a whole with the fixed substrate, the base plate and the heat dissipation fins through a cold forging one-time forming process, which can optimize the firmness of the supporting device and increase the service life of the product.
[0021] In addition, the marine searchlight proposed by the present utility model may also include a support adjustment device for adjusting the irradiation direction of the marine searchlight. As an implementable way, the support adjustment device includes: an electric base, including: a base body, on which a rotatable turntable and a vertically movable screw rod are provided; a controller, connected to the electric base, for controlling the electric base to drive the turntable to rotate or the screw rod to move up and down; two stainless steel fixing blocks, support member mounting holes are provided on both sides of the stainless steel rear lamp barrel, and fixing substrates are arranged on both sides of the radiator corresponding to the support member mounting holes. The fixing substrates, the substrate and the heat dissipation fins are integrally manufactured by a cold forging process; the two stainless steel fixing blocks are respectively fixed on the fixing substrates on the same side; two stainless steel connecting cross plates are respectively fixed on the two stainless steel fixing blocks; a first support member, fixed on the turntable, two first support arms extend outward from both sides of the first support member, and the two first support arms are respectively rotatably connected to the first ends of the stainless steel connecting cross plates on the same side, so that the searchlight body can rotate around the connecting axis of the first support arm and the first end under the action of an external force; and a second support member, fixed on the screw rod and capable of moving up and down synchronously with the screw rod, two second support arms extend outward from both sides of the second support member, and the two second support arms are respectively fixedly connected to the second ends of the stainless steel connecting cross plates on the same side.
[0022] As an alternative way, the support adjustment device can also adopt an adjustment structure in the prior art to realize the control of rotation and the adjustment of the up and down angle of the lamp body. For example, a pan-tilt structure can be directly selected and purchased from various products in the market according to the design requirements, as long as it can adjust the height and angle of the searchlight body.

[0033] As Figures 1-3 The marine searchlight shown includes a searchlight main body 1 and a support device 2. The support device 2 is used to provide support to the searchlight main body 1 so that the marine searchlight can be placed at the installation location.
[0034] The searchlight main body 1 includes: a radiator 11, a stainless steel lamp cylinder 12, an LED integrated light source 13, a driving power supply 14, a combined lens 15, a Fresnel lens 16, and tempered glass 17.
[0035] The radiator 11 is an aluminum radiator, including a substrate 111, heat dissipation fins 112, and a fixed substrate 113 that are integrally formed by a cold forging process. The LED integrated light source 13 is fixed on the substrate 111 of the radiator 11, and the driving power supply 14 is fixed to the rear end of the heat dissipation fins 112 through a stainless steel plate 191.
[0036] The stainless steel lamp cylinder 12 includes a stainless steel fixing ring 121, a stainless steel front lamp cylinder 122, a stainless steel rear lamp cylinder 123, and a stainless steel rear cover plate 124. A plurality of heat dissipation holes 125 are provided on the barrel wall of the stainless steel rear lamp cylinder 123 and the rear cover plate 124. An installation hole 126 is provided on the rear end face of the stainless steel front lamp cylinder 122. Combining Figure 4 And Figure 5As shown, the heat dissipation fins 112 of the radiator 11 pass through the mounting hole 126 in the A1 direction and are arranged outside the stainless steel headlight cylinder 121. The substrate 111 is located at the rear end of the stainless steel headlight cylinder 122 and is fixed to the stainless steel headlight cylinder 122 through the substrate 111. A waterproof silicone rubber is coated on the contact surface between the stainless steel headlight cylinder 122 and the substrate 111. The stainless steel rear light cylinder 123 is sleeved outside the heat dissipation fins 112 in the B1 direction, and the front end surface of the stainless steel rear light cylinder 123 is connected and fixed to the rear end surface of the stainless steel headlight cylinder 122. The rear cover plate 124 is detachably fixed to the rear end of the stainless steel rear light cylinder 123.
[0037] The combined lens 15 is an optical device formed by fixing two or more optical glass lenses together through a specific mechanical structure for integrated use and can be directly purchased on the market according to design requirements. The combined lens 15 is fixed on the substrate 111 of the radiator 11 and is arranged in front of the LED integrated light source 13 in the light emission direction. The Fresnel lens 16 is arranged as a condenser lens inside the stainless steel headlight cylinder 122 and near the front end of the stainless steel headlight cylinder 122. Specifically, as shown in Figure 6 and Figure 7 As shown, at the front end of the barrel wall of the stainless steel headlight cylinder 122, it bulges outwards to form a barrel wall step 1221 on the inner wall. At the same time, there is a flanging 1222 at the edge of the front end port of the barrel wall. The Fresnel lens 16 is clamped on the barrel wall step 1221. The outer edge of the tempered glass 17 is nested with a waterproof gasket 18 and is stacked outside the Fresnel lens 16. The stainless steel fixing ring 121 is sleeved on the flanging 1222 at the front end port edge of the stainless steel headlight cylinder 122 and is fixed by screws 128, so as to lock and fix the Fresnel lens 16 and the tempered glass 17 nested with the waterproof ring 18 in the barrel wall step 1221 inside the front end port of the stainless steel headlight cylinder 122.
[0038] In this embodiment, the thickness of the Fresnel lens 16 is 1 - 5 mm, and the diameter is 100 - 700 mm; the luminous diameter of the luminous surface of the combined lens 15 is 10 - 100 mm. Selecting lenses within this range can enable the LED integrated light source to achieve a better beam condensing effect. The luminous surface of the combined lens refers to the area of the outermost surface lens exposed by the combined lens, that is, a surface where the light rays emitted by the LED light source are refracted by the combined lens and then emitted.
[0039] As shown in Figure 8As shown, the support device 2 includes a support member 21 and two stainless steel fixing blocks 23. The support member 21 is connected to the searchlight body 1 of the marine searchlight through the two stainless steel fixing blocks 23. Specifically, support member mounting holes 127 are formed on both sides of the stainless steel rear lamp cylinder 123, and the positions of the support member mounting holes 127 correspond to the positions of the fixing substrates 113 arranged on both sides of the radiator 11. The two stainless steel fixing blocks 23 are respectively fixed on the fixing substrates 113 on the same side; the support member 21 includes two support arms 211, and the two support arms 211 are respectively rotatably connected to the two stainless steel fixing blocks 23, so that the searchlight body 1 can rotate around the connecting shaft of the support arm 211 and the stainless steel fixing block 23 under the action of an external force.
[0040] As Figure 9 Another preferred embodiment of the marine searchlight proposed by the present utility model as shown. In this embodiment, the marine searchlight body is basically the same as the previous structure. The difference is that: the support device 2 in this embodiment adopts a structure similar to a pan-tilt to achieve control of rotation and adjustment of the up and down angles of the lamp body. And the structure of the searchlight body 1 in this embodiment is basically the same as that of the previous embodiment, so it will not be described in detail below. The support device 2 in this embodiment will be described in detail below.
[0041] As Figure 9 As shown, the searchlight body 1 is connected to the support device 2. Among them, the support device 2 includes: an electric base 25, a rocker 24, two stainless steel fixing blocks 23, two stainless steel connecting cross plates 26, a first support member 21 and a second support member 22.
[0042] Among them, the electric base 25 includes a base main body 251, on which a rotatable turntable 252 and a screw rod 253 that can be lifted and lowered are provided. The rocker 24 is connected to the electric base 25 to control the electric base 25 to drive the turntable 252 to rotate or the screw rod 253 to be lifted and lowered. The electric base 21 and the supporting rocker 24 are both publicly available technologies and can be directly purchased in the open market. Similar to the previous embodiment, at positions corresponding to the positions of the fixed substrates arranged on both sides of the radiator 11 on both sides of the stainless steel rear lamp cylinder 123, support member mounting holes 127 are provided. The two stainless steel fixing blocks 23 are respectively fixed on the fixed substrates on the same side. In this embodiment, the two stainless steel connecting cross plates 26 are respectively fixed on the two stainless steel fixing blocks 23. The bottom of the first support member 21 is fixed on the turntable 252, and two first support arms 211 extend outward from both sides thereof. The two first support arms 211 are respectively rotatably connected to the first ends 261 of the stainless steel connecting cross plates 26 on the same side thereof, so that the searchlight main body 1 can rotate around the connecting shaft of the first support arm 211 and the first end 261 under the action of an external force; the bottom of the second support member 22 is fixed on the screw rod 253 through a connecting piece 193 and can move up and down synchronously with the screw rod 253. Two second support arms 221 extend outward from both sides of the second support member 22. The two second support arms 221 are respectively connected and fixed to the second ends 262 of the stainless steel connecting cross plates 26 on the same side thereof.
[0043] During operation, when the rocker 24 controls the horizontal rotation of the turntable 252 on the electric base 25, since the bottom of the first support member 21 is fixed on the turntable 252, the turntable 252 drives the first support member 21 to rotate synchronously, and then drives the searchlight main body 1 to rotate horizontally; when the rocker 24 controls the screw rod 253 on the electric base 25 to move up and down, the second support member 22 also moves up and down synchronously with the screw rod 253. At this time, since the first support member 21 is fixed on the turntable 252 and does not move up and down synchronously, the second support member 22 will provide an upward (when the screw rod 253 rises) or downward (when the screw rod 253 descends) force to the stainless steel connecting cross plate 26 at the second end 262 of the stainless steel connecting cross plate 26 under the drive of the screw rod 253, and then drive the searchlight main body 1 to rotate around the connecting shaft of the first support arm 211 and the first end 261 itself, so that the lamp head of the searchlight main body 1 rotates upward or downward.
[0044] Although the present utility model has been described above based on preferred embodiments, this does not mean that the scope of the present utility model is only limited to the above structures. As long as those skilled in the art of this technology can easily develop equivalent alternative structures after reading the above description, all equal changes and modifications made without departing from the spirit and scope of the present utility model should be covered within the scope of the present utility model patent.
