The light emitted by the eye-protection lamp overlaps with the blue light from the mobile phone screen, effectively reducing blue light hazards, reducing visual fatigue, and protecting eyesight. It is especially suitable for people who use mobile phones for long periods of time, improving eye health. However, this device has the following problems: firstly, the device is not convenient to install; secondly, the device cannot effectively improve the uniformity of illumination and visual comfort. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. This device features a connector whose rear end is perfectly aligned with the shape of the insertion groove for easy insertion. Furthermore, the automatic alignment and attraction of magnets A and B create a magnetic quick-release connection, solving the problem of inconvenient installation. By incorporating an arc-shaped diffuser with concentric circle diffusion patterns, it achieves uniform and soft surface lighting, addressing the issue of the device's inability to effectively improve light uniformity and visual comfort.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A screen eye-protection lamp for a handheld electronic device includes a lamp holder with a connecting seat at the lower front end. The lamp holder includes a front shell and a rear shell. A PCB board is mounted on the front side of the rear shell. LED beads are soldered to the upper front end of the PCB board. Multiple metal output terminals are provided at the lower front end of the PCB board. A light-emitting port is provided at the upper front end of the front shell. A light-transmitting sheet is embedded in the light-emitting port. An arc-shaped diffuser is provided on the outside of the light-emitting port. A slot groove is provided at the lower front end of the front shell.

[0007] As a preferred embodiment, the front and rear shells are detachably connected to each other on one side via a snap-fit ​​structure to form a complete lamp holder.

[0008] As a preferred embodiment, the socket groove is generally concave and flattened oval, which is adapted to the shape of the rear end of the connector. The rear end of the connector can be embedded in the socket groove. The socket groove has multiple through holes at its center, and magnet strips A are provided at both the upper and lower ends of the socket groove.

[0009] As a preferred embodiment, the connector has a Type-C interface on the front side and a metal input terminal at the center of the rear side. Magnet strips B are provided at both the upper and lower ends of the rear side of the connector, and the positions and shapes of magnet strips B and magnet strips A correspond to each other.

[0010] As a preferred embodiment, the location of the through hole is consistent with the number and location of the metal output terminals and the metal input terminals.

[0011] As another preferred embodiment, the arc-shaped diffuser covers the outside of the light-emitting port and is integrally injection molded with the front shell, and the inner wall of the arc-shaped diffuser is provided with concentric circle diffusion patterns.

[0012] The beneficial effects of this utility model are:

[0013] (1) In this utility model, the rear end of the connector is adapted to the shape of the socket groove so that it can be embedded. The magnet strip B at the rear end of the connector and the magnet strip A in the socket groove are in the same position and shape, which can form a magnetic quick-release connection. Just insert the Type-C interface into the charging port of the electronic device, and then align the socket groove of the lamp holder front shell with the rear end of the connector for magnetic adsorption connection, which is convenient and easy.

[0014] (2) In this utility model, while the connector and the lamp holder are magnetically connected, the metal input terminal of the connector of the PCB board is aligned and contacted in the through hole to achieve electrical conduction, so as to supply power to the LED lamp beads and form a stable current transmission path.

[0015] (3) In this utility model, an arc-shaped diffuser is set to cover the outside of the light-emitting port, and the inner wall is provided with concentric circle diffusion patterns to make the light soft and uniform. When the point light source emitted by the LED beads on the PCB board passes through the light-transmitting sheet and enters the diffuser, the concentric circle patterns perform multiple micro-refractions and scattering of the incident light, so that the originally concentrated bright light is evenly dispersed and transformed into a light source with a wide coverage angle and uniform brightness distribution, creating a comfortable and natural screen eye protection light.

[0016] In summary, this device has the advantages of convenient installation and creating a comfortable and natural screen light for eye protection, making it particularly suitable for the field of screen eye protection lamp technology. Attached Figure Description

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] Example 1

[0025] like Figures 1 to 5 As shown, this utility model provides a screen eye-protection lamp for a handheld electronic device, including a lamp holder 1. The lamp holder 1 has a connecting seat 2 at the lower front end. The lamp holder 1 includes a front shell 11 and a rear shell 12. A PCB board 13 is installed on the front side of the rear shell 12. LED beads 131 are soldered on the upper front end of the PCB board 13. The LED beads 131 are surface-mount LEDs with low blue light hazard level that meet the requirements of human eye visual comfort. The lower front end of the PCB board 13 has multiple metal output terminals 132. The metal output terminals 132 are pin-type contacts. The upper outer side of the front shell 11 has a light-emitting port 111. A light-transmitting sheet 3 is embedded in the light-emitting port 111. An arc-shaped diffuser 115 is provided on the outer side of the light-emitting port 111. The light emitted by the LED beads 131 first passes through the light-transmitting sheet 3 and then enters the diffuser 115. The lower front end of the front shell 11 has a slot groove 112.

[0026] Furthermore, the front shell 11 and the rear shell 12 are detachably connected to each other on one side by a snap-fit ​​structure to form a complete lamp holder 1. The snap-fit ​​structure design allows users to separate the front and rear shells without tools, which is convenient for later maintenance, replacement of PCB board 13 or cleaning of internal components. The rear shell 12 has mounting points evenly distributed around its front periphery, and the front shell 11 has mounting holes at the mounting points around its rear periphery. The mounting points and mounting holes are matched for a snap-fit ​​detachable connection.

[0027] Furthermore, the socket groove 112 is generally concave and flattened, which is adapted to the shape of the rear end of the connector 2. The rear end of the connector 2 can be embedded in the socket groove 112. The socket groove 112 has multiple through holes 113 at its center. The upper and lower ends of the socket groove 112 are provided with magnetic strips A114. The lamp holder 1 can be magnetically attracted to the connector 2 by simply aligning it with the rear end of the connector 2. Alternatively, the connector 2 and the lamp holder 1 can be fixedly injection molded into a single shell without using a magnetic attraction method.

[0028] Furthermore, the connector 2 has a Type-C interface 21 on its front side. The Type-C interface 21 can be directly plugged into the USB port of a smartphone, tablet, or other electronic device that supports Type-C charging. The Type-C interface 21 has a reversible blind insertion characteristic, which improves the user experience. When the connector 2 is plugged into an electronic device, it draws power through the Type-C interface 21. The connector 2 has a metal input terminal 23 at the center of its rear side. The number of metal input terminals 23 is the same as the number of metal output terminals 132 on the PCB board 13, and their positions correspond. They also use pin-type contacts. However, the metal input terminals 23 protrude only slightly from the rear end of the connector 2, so that they can make contact with the metal output terminals 132 within the through hole 113 to power the LED beads 131. The connector 2 has a magnetic strip B22 at both the upper and lower ends of its rear side. The magnetic strip B22 and the magnetic strip A114 are corresponding in position and shape. When the rear end of the connector 2 approaches the insertion groove 112, the magnetic strip B22 and the magnetic strip A114 automatically correct their offset under the action of the magnetic field and quickly attract into place.

[0029] Furthermore, the position of the through hole 113 is consistent with the number and position of the metal output terminal 132 and the metal input terminal 23. The multiple through holes 113 penetrating the center of the socket groove provide a guide channel, so that the metal output terminal 132 on the PCB board and the metal input terminal 23 on the connector can achieve face-to-face contact and conduction inside the through hole 113.

[0030] Furthermore, the arc-shaped soft light cover 115 covers the outside of the light-emitting port 111. The arc-shaped soft light cover 115 has an upwardly convex ellipsoidal shape and is integrally injection molded with the front shell 11. The arc-shaped soft light cover 115 is injection molded first, and then the material of the front shell 11 is added and injection molded to form an integral combination with the arc-shaped soft light cover 115. The inner wall of the arc-shaped soft light cover 115 is provided with concentric circular diffusion patterns. The concentric circular diffusion patterns are ring patterns that radiate outward from the center point of the innermost part of the arc-shaped soft light cover 115. Each concentric circular diffusion pattern unit is equivalent to a refractive surface. When the light source emitted by the LED beads 131 on the PCB board passes through the light-transmitting sheet 3 and enters the arc-shaped soft light cover 115, the concentric circular patterns scatter the incident light multiple times, so that the originally concentrated bright light is evenly dispersed and transformed into a light source with a wide coverage angle and uniform brightness distribution, creating a comfortable and natural screen eye-protection light.

[0031] Working process: First, the user inserts the Type-C interface 21 on the front of the connector 2 into the charging port of the electronic device to draw power. At this time, the magnetic strip B22 on the rear of the connector 2 and the metal input terminal 23 are in a ready-to-connect state. Next, the user aligns the insertion groove 112 at the lower end of the front shell 11 of the lamp holder 1 with the rear end of the connector 2. Under the magnetic attraction of the magnetic strips A114 and B22, the position is automatically corrected and firmly attached. At the same time, the through hole 113 in the center of the insertion groove 112 guides the metal output terminal 132 at the lower end of the PCB board 13 to make precise contact with the metal input terminal 23 of the connector 2, forming a stable electrical circuit. Subsequently, the current is transmitted through the PCB board 13 to the LED bead 131 at the upper end, causing the LED bead 131 to light up.

[0032] Secondly, the light from the LED bead 131 passes through the light-transmitting sheet 3 embedded in the light-emitting port 111 and enters the arc-shaped diffuser 115. The concentric diffusion pattern on the inner wall of the diffuser 115 scatters the light, making the originally concentrated bright light evenly dispersed and transformed into a light source with a wide coverage angle and consistent brightness distribution, creating a comfortable and natural screen eye-protecting light.
