A type of lifting surface-mounted downlight device

Abstract

This utility model discloses a lifting device for surface-mounted downlights, relating to the field of surface-mounted downlight technology. It includes an optical reflector and a rope winch. An aluminum alloy lamp body is mounted on the outside of the optical reflector, and a lamp body rear cover is snapped onto the upper part of the lamp body. A rope pulley is mounted at the bottom of the lamp body rear cover, and an insulated rope is fitted around the outside of the rope pulley. A lifting device aluminum disc is mounted on the upper outer side of the insulated rope. Through the rope winch, when maintenance is required, the lifting device controller activates the lifting motor, causing the rope winch to release the insulated rope. The aluminum alloy lamp body then descends under gravity, lowering the lamp's height. This eliminates the need for a ladder when replacing the internal LED light source, making it safer and more convenient. After maintenance, simply rewind the insulated rope with the rope winch to lift the lamp into its designated slot in the ceiling.

Description

Technical Field

[0001] This utility model relates to the field of surface-mounted downlight technology, specifically a lifting surface-mounted downlight device. Background Technology

[0002] LED surface-mounted downlights are ceiling-mounted downlights that use LEDs as the light source. They belong to the category of directional lighting and feature a focused beam angle design, resulting in concentrated light with high luminous efficacy. By concealing the light source, these lights achieve a unified architectural aesthetic and are characterized by being glare-free, energy-efficient, environmentally friendly, long-lasting, having good color rendering, fast response, and being free of harmful substances such as mercury.

[0003] Existing LED surface-mounted downlights are usually installed on the ceiling. Because the ceiling is high, when the LED is damaged and needs to be replaced, or when it needs to be cleaned and maintained, a ladder is usually required, which makes the operation inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting surface-mounted downlight device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting surface-mounted downlight device, comprising an optical reflector and a rope winch. An aluminum alloy lamp body is mounted on the outside of the optical reflector, and a lamp body rear cover is snapped onto the upper part of the aluminum alloy lamp body. A rope pulley is mounted at the bottom of the lamp body rear cover. An insulated rope is sleeved on the outside of the rope pulley, and a lifting device aluminum disc is mounted on the upper outer side of the insulated rope. A lifting device controller is mounted on the top end of the lifting device aluminum disc. The rope winch is located at the upper end of the insulated rope, and a lifting device sheet metal bracket is rotatably connected to one end of the rope winch. A lifting device motor is mounted on one side of the lifting device sheet metal bracket, and the output end of the lifting device motor is fixedly connected to the rope winch.

[0006] Furthermore, the optical reflector has an optical lens installed inside, and a COB bracket is provided on top of the optical lens, with an LED light source fixed inside the COB bracket.

[0007] Furthermore, an LED driver power supply is provided at one bottom end of the lamp body rear cover, and a power-connecting cylinder is fixed at the top of the lamp body rear cover.

[0008] Furthermore, an electrical contact is disposed at the center of the bottom of the aluminum disc of the lifting device, and a limit contact is provided at the bottom of the aluminum disc of the lifting device.

[0009] Furthermore, there are two energizing cylinders, and each energizing cylinder corresponds to an energizing contact.

[0010] Furthermore, an aluminum alloy cylinder for the lifting device is installed on the outer side of the aluminum disc of the lifting device, and an electrical insulating plate is fixed to the bottom of the aluminum disc of the lifting device.

[0011] Furthermore, the top of the aluminum alloy cylinder of the lifting device is engaged with a rear cover of the lifting device cylinder, and a lifting device mounting bracket is installed on the top of the rear cover of the lifting device cylinder.

[0012] Furthermore, the upper end of the sheet metal bracket of the lifting device is fixedly connected to the rear cover of the cylindrical lifting device, and the lower end of the sheet metal bracket of the lifting device is fixedly connected to the aluminum disc of the lifting device.

[0013] This utility model provides a lifting surface-mounted downlight device, which has the following beneficial effects:

[0014] 1. This utility model, through the setting of the hanging rope winch, when the surface-mounted downlight needs maintenance, the lifting device controller will start the lifting device motor to work, so that the hanging rope winch releases the insulated hanging rope. Therefore, the aluminum alloy lamp body will fall under the action of gravity, reducing the height of the lamp. Thus, when replacing the internal LED light source, there is no need to use a ladder, which is safer and more convenient. After maintenance, similarly, you only need to use the hanging rope winch to rewind the insulated hanging rope to lift the lamp into the groove in the ceiling, which helps to improve the convenience of lamp maintenance.

[0015] 2. This utility model, through the setting of the power-connecting cylinder and the power-connecting contact, allows the power-connecting cylinder on the rear cover of the lamp body to separate from the power-connecting contact on the aluminum disc of the lifting device when the aluminum alloy lamp body moves downward, automatically disconnecting the circuit and thus improving the safety during maintenance. Moreover, when the aluminum alloy lamp body moves upward and resets after maintenance, the power-connecting cylinder contacts the power-connecting contact, making the circuit continuous. Therefore, no additional operation is required, which is very convenient. Furthermore, during the upward movement, the limit contact will also contact the rear cover of the lamp body, causing the hoisting rope winch to stop winding, thus playing a limit protection role.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 5 As shown, a lifting surface-mounted downlight device includes an optical reflector 1 and a rope winch 17. An optical lens 2 is housed inside the optical reflector 1, and a COB bracket 3 is mounted on top of the optical lens 2. An LED light source 4 is fixed inside the COB bracket 3. An LED driver 8 drives the LED light source 4 on the COB bracket 3 to emit light. The light passes through the optical lens 2 and is focused out by the optical reflector 1. An aluminum alloy lamp body 5 is mounted outside the optical reflector 1, and a lamp body rear cover 6 is snapped onto the upper part of the aluminum alloy lamp body 5. A rope pulley 7 is mounted at the bottom of the lamp body rear cover 6 to reduce wear. An LED driver 8 is located at one end of the bottom of the lamp body rear cover 6, and a power-connecting cylinder 9 is fixed to the top of the lamp body rear cover 6. An insulated rope 10 is sleeved on the outside of the rope pulley 7, and a lifting device aluminum disc 11 is mounted on the upper outer side of the insulated rope 10 to improve safety during use. A power contact 12 is installed at the center of the bottom of the aluminum disc 11 of the lifting device, and a limit contact 13 is provided at the bottom of the aluminum disc 11 of the lifting device. When the limit contact 13 contacts the rear cover 6 of the lamp body, the hoisting rope winch 17 stops winding, which plays a limit protection role. In addition, the limit contact 13 is a contact switch contact, and the contact switch is one of the commonly used switches. Therefore, this application will not elaborate on its specific structure and circuit connection. There are two power contact cylinders 9, and the power contact cylinders 9 correspond one-to-one with the power contact 12. When the aluminum alloy lamp body 5 moves down, the power contact cylinders 9 on the rear cover 6 of the lamp body will separate from the power contact 12 on the aluminum disc 11 of the lifting device, automatically disconnecting the circuit, thereby improving the safety during maintenance. An aluminum alloy cylinder 14 of the lifting device is installed on the outside of the aluminum disc 11 of the lifting device, and an insulating plate 15 is fixed at the bottom of the aluminum disc 11 of the lifting device. The insulating plate 15 is used to avoid interference between the two power contact 12.

[0024] like Figures 1 to 4 As shown, a lift controller 16 is mounted on one end of the top of the aluminum disc 11 of the lifter. A rope winch 17 is located at the upper end of the insulated rope 10, and one end of the rope winch 17 is rotatably connected to a sheet metal support 18 of the lifter. A lift motor 19 is mounted on one side of the sheet metal support 18 of the lifter, and the output end of the lift motor 19 is fixedly connected to the rope winch 17. The lift motor 19 is started by the lift controller 16, causing the rope winch 17 to release the insulated rope 10. Therefore, the aluminum alloy lamp body 5 will be lifted under the action of gravity. The height of the lamp is lowered, so that when replacing the internal LED light source 4, there is no need to use a ladder, which is safer and more convenient. The top of the aluminum alloy cylinder 14 of the lifter is connected to the rear cover 20 of the lifter cylinder, and the top of the rear cover 20 of the lifter cylinder is equipped with a lifter mounting bracket 21. The upper end of the sheet metal bracket 18 of the lifter is fixedly connected to the rear cover 20 of the lifter cylinder, and the lower end of the sheet metal bracket 18 of the lifter is fixedly connected to the aluminum disc 11 of the lifter. The lifter mounting bracket 21 can be fixed to the ceiling bracket with bolts.

[0025] In summary, when using this lifting surface-mounted downlight device, firstly, the lifting device mounting bracket 21 is fixed to the ceiling bracket with bolts, and the wiring is connected to the lifting device controller 16 and the electrical contact 12. Then, the aluminum alloy cylinder 14 of the lifting device is snapped onto the rear cover 20 of the lifting device cylinder. Next, when the circuit is connected, the LED driver power supply 8 drives the LED light source 4 on the COB bracket 3 to emit light. The light passes through the optical lens 2 and is emitted under the focusing of the optical reflector 1. Then, after a long period of use, when maintenance of the surface-mounted downlight is required, the lifting device motor 19 is started by the lifting device controller 16, causing the hoisting rope winch 17 to release the insulated hoisting rope 10. Therefore, the aluminum alloy lamp body 5 will fall under the action of gravity, lowering the lamp. The height of the aluminum alloy lamp body 5 allows for safer and more convenient replacement of the internal LED light source 4 without the need for a ladder. Simultaneously, when the aluminum alloy lamp body 5 is lowered, the electrical contact cylinder 9 on the lamp body's rear cover 6 will separate from the electrical contact 12 on the lifting device's aluminum disc 11, automatically disconnecting the circuit and improving maintenance safety. After maintenance, simply rewind the insulated rope 10 using the hoisting rope winch 17. The insulated rope 10 will pull the rope pulley 7, lifting the aluminum alloy lamp body 5 to the ceiling slot. The electrical contact cylinder 9 will then contact the electrical contact 12, connecting the circuit. Furthermore, during the ascent, the limit contact 13 will contact the lamp body's rear cover 6, stopping the hoisting rope winch 17 from rewinding, providing a limit protection function.
