Description

Technical Field

[0001] The invention relates to the technical field of industrial and mining lamps, and in particular to an industrial and mining lamp capable of electrically zooming. Background Art

[0002] LED mining lamps, also known as high ceiling lamps, are lighting devices that mainly use light-emitting diodes as light sources. They are energy-efficient indoor LED lamps. They are gradually coming into people's view with their advantages such as directional light emission, low power consumption, good driving characteristics, fast response speed, high seismic resistance, long service life, and green environmental protection. They can be widely used in industrial plants, production workshops, supermarkets, sports and entertainment venues, warehouses and other scenes.

[0003] LED mining lamps are mainly composed of a driving power supply, an aluminum alloy heat sink, a light source, and a PC lens. The lighting beam angle of existing LED mining lamps is mainly constrained by the PC lens to produce the required angle. There are currently two technical approaches: 1. A lens design with a fixed single beam angle, the beam angle cannot be changed after the product is produced; 2. Manual three-speed rotation to adjust the lens zoom. After production is completed, the LED mining lamp can be manually switched between the three different beam angles set according to demand.

[0004] However, for industrial and mining lamps with a fixed single beam angle lens design, the following problems exist in actual use: 1. Due to factors such as installation errors in actual construction, the products purchased according to the originally designed beam angle do not meet the construction requirements and acceptance standards, and the non-compliant products need to be disassembled and replaced through aerial work with ladder equipment; 2. For environmental protection and energy saving, when facing multiple beam angles, LED industrial and mining lamps with a fixed single beam angle need to open several sets of molds, which doubles the energy and material consumption of the product, greatly reducing the production and installation efficiency.

[0005] For industrial and mining lamps with manual three-speed rotating lens zoom adjustment, the following problems exist in actual use: 1. During the construction process, due to construction and installation errors and other problems in some locations, the lighting beam angle is too large or too small. Therefore, it is necessary to use a ladder truck to perform a second manual adjustment on the installed lamps to switch to the appropriate beam angle, which leads to an increase in manpower, material and financial resources expenditures, and there is a problem of high difficulty in operation.

[0006] In summary, the LED mining lamps currently on the market have some shortcomings in practical applications, especially the inconvenience in on-site adjustment, the difficulty of operation, and the problem of additional operating costs due to secondary operations.

[0007] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

[0029] See also Figures 1 to 4 The present invention provides an industrial and mining lamp with electric zoom, comprising a housing 1, a lens 2, a radiator 31, a lamp board 4, an electric focusing mechanism and a controller 6, wherein the lens 2 can move relative to the housing 1, and the lamp board 4 is located between the lens 2 and the housing 1; one end of the radiator 31 is fixedly connected to the housing 1, and the other end of the radiator 31 passes through the lamp board 4 and the lens 2; the controller 6 is arranged at the other end of the radiator 31, and the electric focusing mechanism is electrically connected to the controller 6; the fixed end of the electric focusing mechanism is located in the radiator 31, and the transmission end of the electric focusing mechanism is transmission-connected to the lens 2, and the electric focusing mechanism is used to adjust the distance between the lens 2 and the lamp board 4

[0030] The present invention discloses an industrial and mining lamp with electric zoom, which has the advantage of a relatively compact overall structure. The lens 2 can move relative to the shell 1, and the controller 6 feeds back the adjustment distance to the electric focusing mechanism, so that the electric focusing mechanism drives the lens 2 to move up and down to adjust the distance between the lens 2 and the lamp board 4, thereby realizing electric focusing. The focal length of the industrial and mining lamp can be adjusted on-site according to on-site use requirements, and the lamp has high flexibility of use and low adjustment difficulty, so that the focusing operation becomes simpler and more efficient, and the user's operating experience is improved. Furthermore, since the radiator 31 runs through the entire industrial and mining lamp, the stability of the industrial and mining lamp during operation can be improved, so as to achieve the purpose of fast and effective heat conduction, reduce mechanical deformation caused by temperature changes, and ensure accurate focusing of the optical system.

[0031] In this embodiment, the controller 6 may include a wireless communicator to receive wireless control instructions sent by the user. The wireless communicator is a prior art, such as a WIFI wireless communicator.

[0032] For further information, see Figures 2 to 4 The electric focusing mechanism includes a control circuit board 51, a motor 52 and a gear shaft 53; a climbing step 21 is provided on the side of the lens 2; the control circuit board 51 is electrically connected to the motor 52 and the controller 6 respectively; the motor 52 is fixed in the radiator 31, and a driving gear 521 is provided at the output end of the motor 52, and a driven gear 531 is provided at one end of the gear shaft 53, and the driving gear 521 is meshed with the driven gear 531; the other end of the gear shaft 53 passes through the radiator 31 and is provided with a first rack 532, and a second rack is provided on the climbing step 21, and the first rack 532 is meshed with the second rack.

Furthermore, the motor 52 is built into the radiator 31, which not only effectively utilizes the space, but also timely dissipates the heat of the working motor 52 through the radiator 31, which can improve the operating efficiency and service life of the motor 52.
