Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a computer screen hanging light. Background Technology

[0002] Traditional lighting fixtures are mostly fixed and bulky, such as chandeliers, recessed lights, and table lamps. When users only need local lighting or localized enhanced lighting, such as only needing to illuminate a screen (e.g., a desktop computer screen, a laptop screen), they generally use lamps placed near the screen. These lamps not only take up desktop space, but the illuminated area is also difficult to adjust to a suitable position. For this reason, screen hanging lights have emerged. Screen hanging lights are lights that are hung on the monitor, which can automatically supplement the ambient light in the office area, without taking up space, avoiding eye fatigue and discomfort, and are suitable for people who work with monitors for long periods of time.

[0003] The prior art (announcement number: CN218268693U, announcement date: 2023.01.10) discloses a screen light holder, in which the first clamping surface and the second clamping surface are arranged opposite to each other, so that both the first clamping surface and the second clamping surface abut against the display, and both the first clamping component and the second clamping component are in surface contact with the display, so as to avoid damage to the display caused by excessive pressure from the first clamping component or the second clamping component.

[0004] The aforementioned screen light can be installed and suspended on the screen, saving desktop space. It also features angle adjustment, allowing for adjustment of the illuminated area on the desktop. However, in the above solution and existing screen lights, because the light strip is very close to the screen display area, it creates reflections on the screen display area when turned on, with the light direction as follows: Figure 12 As shown, this causes the screen's display area to reflect light directly onto the light strip, resulting in glare and severely impacting the user experience. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0006] A computer screen light includes a hanging component and a lamp profile. The hanging component is suspended from the upper edge of the computer screen, and the lamp profile is fixed to the front of the hanging component by screws. A light-emitting groove is formed on the bottom side of the lamp profile, and a light strip is installed inside the lamp profile. The angle between the light strip and the light-emitting groove is an acute angle. A light-concentrating sheet is installed inside the lamp profile, covering the bottom side of the light strip, and the light strip is focused into the light-emitting groove by the light-concentrating sheet. A light-absorbing sheet is installed inside the lamp profile, and the light-absorbing sheet is vertically arranged inside the light-emitting groove.

[0007] Furthermore: a light-diffusing plate is installed inside the light-emitting slot, and the light strip is focused onto the light-diffusing plate by a light-concentrating sheet.

[0008] Furthermore, the included angle between the light strip and the light-diffusing plate is between 15-45°.

[0009] Furthermore, the light-absorbing sheet is vertically disposed on the light-diffusing plate.

[0010] Furthermore: two oblique reflectors are installed inside the lamp profile, and the oblique reflectors are respectively arranged on the front and rear sides of the focusing sheet.

[0011] Furthermore, the side of the lamp profile is formed with several insertion slots, and the lamp strip, light diffuser, light focusing sheet, light absorbing sheet and oblique reflector are inserted into the insertion slots of the lamp profile one by one from the side gap.

[0012] Furthermore, the focusing sheet is a convex lens.

[0013] Furthermore: a circuit board is installed inside the lamp profile, and the circuit board and the lamp strip are electrically connected to each other.

[0014] Furthermore, several control buttons are embedded on the circuit board.

[0015] Furthermore, a distance sensor is embedded in the front side of the circuit board, and a buzzer is electrically connected to the circuit board.

[0016] Furthermore, the distance sensor is either an ultrasonic sensor or an infrared sensor.

[0017] Furthermore, the circuit board is equipped with an input interface, which is a Type-C interface.

[0018] Furthermore, the light-absorbing sheet is made of light-absorbing cotton.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. A light-absorbing sheet is installed inside the lamp profile. When the light strip shines on the light-absorbing sheet, the light cannot be reflected. Therefore, when the lamp strip is used on the screen, there will be no light reflection on the screen.

[0043] like Figure 1-11As shown, this utility model discloses a computer screen hanging light, comprising a hanging component 1 and a lamp profile 2. The hanging component 1 is suspended and installed on the upper edge of the computer screen, and the lamp profile 2 is fixedly installed on the front side of the hanging component 1 by screws. A light-emitting groove 3 is formed on the bottom side of the lamp profile 2, and a light strip 4 is installed inside the lamp profile 2. The included angle between the light strip 4 and the light-emitting groove 3 is an acute angle. A light-concentrating sheet 5 is installed inside the lamp profile 2, covering the bottom side of the light strip 4, and the light strip 4 is focused into the light-emitting groove 3 by the light-concentrating sheet 5. A light-absorbing sheet 6 is installed inside the lamp profile 2, and the light-absorbing sheet 6 is vertically arranged inside the light-emitting groove 3.

[0044] The principle is as follows: A light-absorbing sheet 6 is installed inside the lamp profile 2. When the light strip 4 shines on the light-absorbing sheet 6, the light cannot continue to be reflected. Therefore, when it is used on the screen, there will be no reflection of the light strip 4 onto the screen. In addition, the angle of the lamp profile 2 can be adjusted by using the hanging part 1, thereby adjusting the illumination angle so that the light can shine on the table for illumination without taking up table space and making it convenient for actual use.

[0045] Furthermore, a light-diffusing plate 7 is installed inside the light-emitting slot 3, and the light strip 4 is focused onto the light-diffusing plate 7 by the light-concentrating sheet 5; the light illuminates the tabletop after passing through the light-diffusing plate 7, which can achieve the technical effect of anti-glare.

[0046] Furthermore, the angle between the light strip 4 and the light-diffusing plate 7 is between 15-45°; preferably 26°, which can effectively illuminate the desktop in front of the computer screen and also makes it easy to adjust the illumination angle for use.

[0047] Furthermore, the light-absorbing sheet 6 is vertically disposed on the light-diffusing plate 7; the arrangement of the light-absorbing sheet 6 can prevent light from being reflected onto the display area of ​​the screen, thereby avoiding screen glare and making it more comfortable for the eyes to use.

[0048] Furthermore, two oblique reflectors 8 are installed inside the lamp profile 2, and the oblique reflectors 8 are respectively arranged on the front and rear sides of the light-concentrating sheet 5; the arrangement of the two oblique reflectors 8 can reduce light loss and allow more light to shine on the desktop in front of the computer screen.

[0049] Furthermore, the angle between the light strip 4 and the oblique reflector 8 on the rear side is between 30° and 90°, which can effectively utilize the reflection of light to achieve the effect of illuminating the desktop.

[0050] Furthermore, the angle between the light strip 4 and the front oblique reflector 8 is between 100-160°.

[0051] Furthermore, the side of the lamp profile 2 is formed with several insertion slots 9. The light strip 4, light diffuser 7, light focusing sheet 5, light absorbing sheet 6 and oblique reflector 8 are inserted into the insertion slots 9 of the lamp profile 2 from the side gaps in a corresponding manner. The installation of each component can be completed by side insertion. If a component is damaged, it can be replaced individually, reducing maintenance costs.

[0052] Furthermore, the light-concentrating sheet 5 is a convex lens, which can effectively concentrate light and make the light more focused.

[0053] Furthermore, a circuit board 10 is installed inside the lamp profile 2, and the circuit board 10 and the lamp strip 4 are electrically connected to each other; the brightness of the lamp strip 4 can be controlled by the circuit board 10, thus facilitating practical use.

[0054] Furthermore, the circuit board 10 is equipped with several control buttons 11; the light strip 4 can be turned on and off by controlling the control buttons 11, which is convenient for actual use.

[0055] Furthermore, a distance sensor 12 is embedded in the front side of the circuit board 10, and a buzzer is electrically connected to the circuit board 10. When the circuit board 10 is suspended and mounted on a computer screen for use, the circuit board 10 can sense the distance between itself and the user's eyes through the distance sensor 12. When the distance is less than 50 centimeters for 30 consecutive seconds, the circuit board 10 controls the buzzer to sound, which is used to remind the user that their eyes are too close to the screen, thereby preventing the blue light from the computer screen from causing adverse effects on the eyes. The accompanying drawings of this utility model provide a circuit structure diagram of the circuit board 10, the control button 11, and the distance sensor 12, which can clearly express the control method.

[0056] Furthermore, the distance sensor 12 is either an ultrasonic sensor or an infrared sensor.

[0057] Furthermore, the front side of the lamp profile 2 is formed with a slot 13, and the control button 11 and the distance sensor 12 are both set in the slot 13; the slot 13 can avoid the control button 11 and the distance sensor 12, thereby achieving the technical effect of detecting distance and controlling the light strip 4.

[0058] Furthermore, the circuit board 10 is equipped with an input interface 14, which adopts a Type-C interface; the circuit board 10 can be powered by direct power supply or built-in power supply, thereby ensuring that the screen light can be turned on for a long time.

[0059] Furthermore, the light-absorbing sheet 6 is made of light-absorbing cotton; it has good light-absorbing properties and can effectively prevent the light strip 4 from reflecting onto the display area of ​​the computer screen.

[0060] Furthermore, the suspension component 1 includes a suspension plate 1.1, a front hinge 1.2, and a rear hinge 1.3. The front hinge 1.2 is rotatably mounted on the front side of the suspension plate 1.1, and the rear hinge 1.3 is rotatably mounted on the rear side of the suspension plate 1.1. A suspension edge 15 is formed at the front edge of the bottom side of the suspension plate 1.1. Damping rubber is installed at the rotatable joints between the front hinge 1.2, the rear hinge 1.3, and the suspension plate 1.1. It can be installed on computer screens of various thicknesses at any time through the rotatable joint of the front hinge 1.2 and the rear hinge 1.3. At the same time, the damping rubber allows the front hinge 1.2 and the rear hinge 1.3 to lock themselves after rotating at a certain angle, preventing the screen light from falling off and improving installation stability.

[0061] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
