Description

Technical Field

[0001] This application relates to the field of lighting fixtures, and in particular to a searchlight. Background Technology

[0002] A handheld searchlight is a high-intensity, portable lighting tool whose core function is to provide illumination for specific scenarios by projecting strong light over long distances. It is widely used in professional search and rescue operations, industrial inspection, special operations (ocean-going vessels, power line repair, railway maintenance, etc.), and outdoor exploration.

[0003] However, common handheld searchlights only have one power supply mode, making them unsuitable for various application scenarios. Utility Model Content

[0004] Therefore, it is necessary to provide a searchlight that can adapt to a variety of application scenarios.

[0005] This application provides a searchlight, including: a main body, an illumination part, and a power supply part. The illumination part is disposed on the main body, and the power supply part includes a first power supply and a second power supply, which can independently supply power to the illumination part.

[0006] In one embodiment, the searchlight further includes a circuit switcher for switching the power supply mode of the power supply unit. The power supply mode includes a first power supply mode powered by the first power source and a second power supply mode powered by the second power source. It is understood that this configuration allows for manual switching of the power supply mode via the circuit switcher, making operation very convenient.

[0007] In one embodiment, the first power supply and the second power supply are respectively disposed in different independent circuits, or the first power supply and the second power supply are disposed in the same circuit.

[0008] In one embodiment, the first power supply is set as the primary power supply, and the second power supply is set as the backup power supply. A voltage identifier is provided on the circuit connecting the power supply unit and the lighting unit. The voltage identifier is used to identify the voltage on the circuit and, when the voltage on the circuit is lower than a preset value, to switch the circuit to be powered by the second power supply. It is understood that by setting the first power supply as the primary power supply and the second power supply as the backup power supply, this embodiment can meet the long-term lighting needs of the searchlight while avoiding frequent replacement of the power supply, thereby reducing operating costs. Since the voltage drops rapidly when the power supply is about to run out, the voltage identifier can identify the power consumption of the first power supply, and automatically switch the circuit to be powered by the second power supply when the first power supply is low. This is very convenient and does not require user operation, and avoids damage to the power supply performance caused by the first power supply running out of power.

[0009] In one embodiment, the illumination unit is rotatably connected to one end of the main body. It is understood that this arrangement allows for adjustment of the illumination angle, improving the flexibility and convenience of using the searchlight.

[0010] In one embodiment, the main body includes a grip and a base located at one end of the grip, with the illumination unit located at the end of the grip away from the base. It is understood that this configuration allows the searchlight to be held by hand via the grip and also placed on the base, thus adapting the searchlight to various usage scenarios.

[0011] In one embodiment, one of the first power source and the second power source is located within the grip, and the other is located within the base. It is understood that this arrangement allows for efficient use of the internal space of the base and the grip.

[0012] In one embodiment, the base is provided with a suspension part, and the suspension part and the base are rotatably connected.

[0013] In one embodiment, the suspension part includes a suspension body and a hook, wherein the suspension body is rotatably connected to the base, and the hook is rotatably connected to the suspension body. It is understood that with this configuration, the suspension part can rotate relative to the base, and simultaneously, the hook of the suspension part can rotate relative to the suspension body, thereby making it very convenient to hang the searchlight on objects that are inconvenient to pass through, such as ropes, thus making hanging use more convenient.

[0014] In one embodiment, one of the first power source and the second power source is non-removably disposed in the main body, while the other is detachably disposed in the main body; and / or, the first power source is a lithium battery, nickel-metal hydride battery, lead-acid battery, or lithium iron phosphate battery; and / or, the second power source is a dry cell battery, lithium battery, nickel-metal hydride battery, lead-acid battery, or lithium iron phosphate battery. It is understood that since one of the first power source and the second power source is non-removably disposed in the main body, while the other is detachably disposed in the main body, the power supply unit includes both detachable and non-removable parts. This allows for replacement of the first or second power source by disassembly and installation, or direct charging without disassembling the first or second power source. The first power source is a lithium battery, nickel-metal hydride battery, lead-acid battery, or lithium iron phosphate battery, and is a rechargeable battery that can be repeatedly charged. The second power source is a dry cell battery, lithium battery, nickel-metal hydride battery, lead-acid battery, or lithium iron phosphate battery; that is, the second power source can be either a non-rechargeable or rechargeable battery.

[0015] Compared with the prior art, the searchlight provided in this application has two power supply modes by setting a first power supply and a second power supply. When in use, the lighting part can be powered by either the first power supply or the second power supply. When either the first power supply or the second power supply is depleted, the lighting part can be powered by the other power supply, thereby extending the usage time of the searchlight. It can be seen that the searchlight is applicable to a variety of application scenarios. Attached Figure Description

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0026] Please see Figures 1 to 3This application provides a searchlight, including a main body 10, an illumination part 20, and a power supply part 30. The illumination part 20 is disposed on the main body 10. The power supply part 30 includes a first power supply 31 and a second power supply 32, which can independently supply power to the illumination part 20. Thus, by providing the first power supply 31 and the second power supply 32, the searchlight can have two power supply modes. During use, the illumination part 20 can be powered by either the first power supply 31 or the second power supply 32. When either the first power supply 31 or the second power supply 32 is depleted, the other power supply 31 can be used to power the illumination part 20, thereby extending the searchlight's operating time. Therefore, this searchlight is suitable for various application scenarios.

[0027] Furthermore, one of the first power supply 31 and the second power supply 32 is non-removably disposed in the main body 10, while the other is detachably disposed in the main body 10. Thus, the power supply unit 30 includes both detachable and non-removable parts, allowing the first power supply 31 or the second power supply 32 to be replaced by disassembly and installation, or charging to be achieved directly without disassembling the first power supply 31 or the second power supply 32. It is understood that the non-removable power supply (first power supply 31 or second power supply 32) can be configured as a rechargeable power supply, allowing for repeated charging and use, as the power supply does not need to be disassembled. The detachable power supply (first power supply 31 or second power supply 32) can be configured as either a rechargeable or non-rechargeable power supply, allowing for replacement with a new power supply or charging through disassembly.

[0028] Furthermore, the searchlight also includes a circuit switch 40, which is used to switch the power supply mode of the power supply unit 30. The power supply modes include a first power supply mode powered by a first power source 31 and a second power supply mode powered by a second power source 32. In this way, the power supply mode of the power supply unit 30 can be manually switched via the circuit switch 40, making operation very convenient.

[0029] Furthermore, the circuit switching component 40 is configured as a button or push button. Buttons or push buttons have a relatively simple structure, are easy to operate, and are very convenient to use.

[0030] In one embodiment, the first power supply 31 and the second power supply 32 are respectively disposed in different independent circuits, so that the two independent circuits do not interfere with each other. However, it is not limited to this. In other embodiments, the first power supply 31 and the second power supply 32 can also be disposed in the same circuit, for example, they can be disposed in a parallel circuit, so that the first power supply 31 and the second power supply 32 can independently supply power to the lighting unit 20.

[0031] Furthermore, the first power supply 31 is set as the primary power supply, and the second power supply 32 is set as the backup power supply. A voltage identifier (not shown) is provided on the circuit connecting the power supply unit 30 and the lighting unit 20. The voltage identifier is used to identify the voltage on the circuit and to switch the circuit to be powered by the second power supply 32 when the voltage on the circuit is lower than a preset value. In this embodiment, by setting the first power supply 31 as the primary power supply and the second power supply 32 as the backup power supply, the long-term illumination needs of the searchlight can be met, and the frequent replacement of new power supplies can be avoided, thereby reducing the operating cost. Since the voltage drops rapidly when the power supply is about to run out, the voltage identifier can identify the power consumption of the first power supply 31, and automatically switch the circuit to be powered by the second power supply 32 when the power of the first power supply 31 is low. This is very convenient and does not require user operation, and avoids damage to the power supply performance caused by the first power supply 31 running out of power.

[0032] Please see Figure 2 and Figure 3 In one embodiment, the illumination unit 20 is rotatably connected to one end of the main body 10. This allows for adjustment of the illumination angle of the illumination unit 20, improving the flexibility and convenience of using the searchlight.

[0033] In this embodiment, the lighting unit 20 is rotatably connected to the main body 10 via a bracket 50. The bracket 50 can be fixedly connected to the main body 10 and rotatably connected to the lighting unit 20. Furthermore, the bracket 50 and the lighting unit 20 can be interference-fitted via protruding ribs, thereby allowing the lighting unit 20 to be fixed at any angle. That is, the lighting unit 20 can rotate relative to the bracket 50 at multiple angles, and after rotating at a certain angle relative to the bracket 50, the lighting unit 20 can maintain that rotational position, thus making it more convenient to use.

[0034] It is understood that the wiring connecting the lighting unit 20 and the power supply unit 30 can be arranged along the bracket 50. The circuit switching unit 40 can be arranged on the bracket 50 or on the main body 10, and this application does not limit this.

[0035] Furthermore, the main body 10 includes a grip 11 and a base 12 located at one end of the grip 11, and an illumination unit 20 is located at the end of the grip 11 away from the base 12. In this way, the searchlight can be held by hand via the grip 11 or placed on the base 12, for example, on the ground, a table, or a platform, thus adapting the searchlight to various usage scenarios.

[0036] Furthermore, one of the first power source 31 and the second power source 32 is located within the grip portion 11, and the other is located within the base 12. This allows for efficient use of the internal space of the base 12 and the grip portion 11. Furthermore, one of the first power source 31 and the second power source 32 is non-removably located within the grip portion 11 and is a rechargeable power source, while the other is detachably located within the base 12. This allows the non-removable power source to be repeatedly charged and used, while the detachable power source, located within the base 12, facilitates easier disassembly. In this embodiment, the first power source 31 is non-removably located within the grip portion 11, and the second power source 32 is detachably located within the base 12. This allows for replacement of the second power source 32 via the bottom surface of the base 12, making it more convenient to use. Furthermore, the first power source 31 is a rechargeable power source and has a charging interface for charging. The charging interface of the first power source 31 can be located within the base 12, the grip portion 11, or the bracket 50; this application does not impose any limitations on this.

[0037] Furthermore, the base 12 is provided with a suspension part 60, which is rotatably connected to the base 12. Thus, by providing the suspension part 60, the searchlight can be suspended for use, making it more convenient.

[0038] Furthermore, the suspension part 60 includes a suspension body 61 and a hook 62. The suspension body 61 is rotatably connected to the base 12, and the hook 62 is rotatably connected to the suspension body 61. In this way, the suspension part 60 can rotate relative to the base 12, and at the same time, the hook 62 of the suspension part 60 can rotate relative to the suspension body 61, so that the searchlight can be easily hung on objects that are inconvenient to pass through, such as ropes, making the suspension use more convenient.

[0039] Furthermore, the first power source 31 is preferably a lithium battery, which has advantages such as high energy density, lightweight, long life, fast charging, energy saving and environmental protection. However, it is not limited to this. The first power source 31 can also be a nickel-metal hydride battery, a lead-acid battery, a lithium iron phosphate battery, etc. This application does not limit it.

[0040] In one embodiment, the second power source 32 is a dry cell battery, which is small in size, lightweight, easy to carry, and inexpensive. However, it is not limited to this; the second power source 32 can also be a lithium battery, nickel-metal hydride battery, lead-acid battery, lithium iron phosphate battery, etc.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
