Description

Technical Field

[0001] This utility model belongs to the field of lighting technology, and in particular relates to a leakage-proof lamp holder for double-ended lamp tubes. Background Technology

[0002] During the installation of double-ended fluorescent tubes, factors such as material properties, manufacturing processes, or external conditions can easily lead to a weak current flowing in a path where it shouldn't. This current is called leakage current. The presence of leakage current poses a significant safety hazard to installation personnel.

[0003] The utility model patent with publication number CN217714605U discloses a leakage-proof LED tube, including a lamp cover with plugs installed at both ends. Conductive pins for connecting to lamp holders are provided through the plugs. The plugs include a left plug and a right plug, on which a switch board and a power board are respectively installed. The plugs have clamping grooves for holding the switch board and the power board. The conductive pins are respectively installed on the switch board and the power board. The switch board is equipped with a limit switch that turns the power on and off by touch. The push rod of the limit switch extends outward through the left plug. When the lamp tube is not inserted into the lamp holder, the limit switch is not turned on. When the lamp tube is installed in the two lamp holders, the lamp holder touches the push rod and pushes it into the left plug to turn on the circuit. This ensures that the lamp tube is only powered when it is installed in the lamp tube bracket, thus solving the risk of electric shock when installing the lamp tube. Utility Model Content

[0004] During the installation of double-ended lamps, the lamp head lacks a protective structure to protect the installer and isolate leakage current. The presence of leakage current poses a significant safety hazard to the installer.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a leakage-proof lamp holder for double-ended lamp tubes, including a lamp holder sleeve, a lever groove provided on the upper part of the lamp holder sleeve, a strip-shaped lever provided in the lever groove, and a lever clamp extending into the lamp holder sleeve at the lower end of the strip-shaped lever; a power-off switch connected to the internal circuit of the double-ended lamp tube is provided inside the lamp holder sleeve, and a lever is provided on the power-off switch to control the on / off state, and the lever clamp clamps and fixes the lever.

[0006] Specifically, the pry pliers include a first plier body and a second plier body with identical structures. The upper ends of the first plier body and the second plier body are connected to a strip-shaped pry bar. The first plier body and the second plier body are symmetrical about each other with the central axis of the strip-shaped pry bar as the axis of symmetry.

[0007] Specifically, the lower ends of the first and second clamps are provided with barbed structures, which clamp and fix the lever.

[0008] Specifically, the strip-shaped paddle moves the paddle pliers left and right within the paddle slide groove. During this movement, the paddle pliers clamp the lever and move it left and right. When the strip-shaped paddle moves to both ends of the paddle slide groove, it drives the paddle pliers to move the lever, thus controlling the power-off switch to open or close.

[0009] Specifically, the upper surface of the strip-shaped paddle has several evenly arranged round raised dots.

[0010] Specifically, the lamp holder sleeve has a cylindrical cap-shaped structure, with a lamp post wiring hole on one side of the cap, and a wiring sleeve on the wiring hole.

[0011] Specifically, the lamp holder sleeve, strip-shaped lever, lever pliers, lever, and wiring sleeve are all made of insulating material. The power-off switch is connected to the internal circuitry of the lamp tube; when the power-off switch is off, the internal circuitry of the lamp tube is not energized.

[0012] The beneficial effects of this invention are: it can change the common design of internal leakage current detection chips or external plug-in control on / off to a combined internal and external control method to eliminate leakage current problems. This dual internal and external control method improves the stability and safety of the control. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Example 1: A leakage-proof lamp holder for a double-ended lamp tube includes a lamp holder sleeve 1. The upper part of the lamp holder sleeve 1 is provided with a lever groove 3. A strip-shaped lever 2 is provided in the lever groove 3. The lower end of the strip-shaped lever 2 is provided with a lever clamp 4 extending into the interior of the lamp holder sleeve 1. The lamp holder sleeve 1 is provided with a power-off switch 6 that connects to the internal circuit of the double-ended lamp tube. The power-off switch 6 is provided with a lever 5 to control the on / off state. The lever clamp 4 clamps and fixes the lever 5.

[0020] Leakage current refers to a small current that flows in a circuit or device but should not, due to factors such as material properties, manufacturing processes, or external conditions. This leakage current can affect the normal operation of the circuit, leading to decreased equipment performance or malfunction. In the lighting industry, leakage current is a requirement for the design of double-ended lamps. Although this leakage current is small, it poses a significant safety hazard to installers and operators. With the continuous development of science and technology and culture, and the increasing importance of human safety in various fields, lighting products are indispensable in human life. Therefore, regarding the leakage current safety of double-ended lamps, the North American market was the first to regulate leakage current testing through standards, and the European Union and other countries around the world also have corresponding regulations on this issue.

[0021] Most existing leakage protection devices use residual current devices (RCDs), which are installed in the circuit and automatically cut off the power supply when leakage is detected to prevent electric shock. However, this design requires additional installation and circuit modification, and different adaptations are needed for different lamps, making it very inconvenient to use.

[0022] Therefore, a design is needed that can avoid leakage current problems while possessing high adaptability and easy assembly to ensure the safety of installation personnel in the lighting industry. To expand application scenarios and improve product applicability, this embodiment uses a physical structure design to implement leakage current protection measures. Therefore, a leakage-proof lamp holder for double-ended lamp tubes is designed. This lamp holder design is suitable for most double-ended lamp tubes. The external leakage-proof physical structure controls the internal circuit's power-off switch 6. Before installation, the internal circuit is disconnected via the power-off switch 6, ensuring that the lamp tube's circuit is disconnected during installation, thus eliminating the risk of electric shock from leakage current.

[0023] The strip-shaped paddle 2 can drive the paddle pliers 4 to move left and right within the paddle slide groove 3. During movement, the paddle pliers 4 clamp the lever 5 and move it left and right. When the strip-shaped paddle 2 moves to either end of the paddle slide groove 3, it correspondingly drives the paddle pliers 4 to move the lever 5, controlling the power-off switch 6 to open or close. In this embodiment, when the strip-shaped paddle 2 is at the leftmost end of the paddle slide groove 3, it is in the power-off position. At this time, the paddle pliers 4 control the lever 5 to move to the leftmost end of the power-off switch 6, and the power-off switch 6 is in the off state. When the strip-shaped paddle 2 is at the rightmost end of the paddle slide groove 3, it is in the power-on position. At this time, the paddle pliers 4 control the lever 5 to move to the rightmost end of the power-off switch 6, and the power-off switch 6 is in the on state.

[0024] In this embodiment, the upper surface of the strip-shaped paddle 2 is provided with several evenly arranged round protrusions. The round protrusions increase the friction between the strip-shaped paddle 2 and the user's fingers, making it easier for the user to move the paddle. Since the strip-shaped paddle 2 is connected to the paddle pliers 4 to control the lever 5, moving the paddle is relatively difficult. The round protrusions increase the friction, making it easier for the user to exert force.

[0025] The lamp holder sleeve 1 is a cylindrical cap-shaped structure. A lamp post wiring hole is provided on one side of the cap top, and a wiring sleeve 7 is provided on the wiring hole.

[0026] The lamp holder sleeve 1, strip-shaped lever 2, lever pliers 4, lever 5, and wiring sleeve 7 are all made of insulating material. The power-off switch 6 is connected to the internal circuit of the lamp tube; when the power-off switch 6 is off, the internal circuit of the lamp tube is not energized.

[0027] In this embodiment, the lever is made of non-conductive plastic, and the lever 5 of the DIP switch in contact with it is also made of non-conductive plastic. The lamp tube is installed inside the lamp fixture, and the pin is also located inside the lamp fixture. At this time, regardless of whether the lamp fixture is energized during the replacement process, there is no risk of electric shock to personnel. Furthermore, the leakage protection structure of this lamp holder is a physical structure; this method is based on physical structure control and does not affect the use of multiple lamps simultaneously.

[0028] Before installing the double-ended lamp tube with the leakage protection lamp holder of this application, move the strip-shaped lever 2 to the power-off position. At this time, the lever 4 below the strip-shaped lever 2 controls the lever 5 to contact the power-off contact inside the power-off switch 6, and the power-off switch 6 disconnects the internal circuit. Its working principle is as follows: Figure 4 As shown, for a double-ended lamp, regardless of whether the live wire (L) or the neutral wire (N) is installed first, the lamp's circuit remains open during installation, thus eliminating the risk of electric shock due to leakage current.

[0029] After the lamp tube is installed, the pin is located inside the lamp. Move the strip-shaped lever 2 to the power-on position. At this time, the lever 4 drives the lever 5 to contact the power-on contact of the power-off switch 6. The power-on switch closes the internal circuit, and the circuit can work normally.

[0030] This invention achieves leakage protection through a physical structure, making it applicable to all double-ended lamps requiring leakage current avoidance. It is safe, stable, and effective. It transforms the original design of an internal leakage current detection chip or external plug-in control into a combined internal and external control method to eliminate leakage current problems. This dual control approach improves both stability and safety.

[0031] Example 2: A leakage-proof lamp holder for a double-ended lamp tube includes a lamp holder sleeve 1. The upper part of the lamp holder sleeve 1 is provided with a lever groove 3. A strip-shaped lever 2 is provided in the lever groove 3. The lower end of the strip-shaped lever 2 is provided with a lever clamp 4 extending into the interior of the lamp holder sleeve 1. The lamp holder sleeve 1 is provided with a power-off switch 6 that connects to the internal circuit of the double-ended lamp tube. The power-off switch 6 is provided with a lever 5 to control the on / off state. The lever clamp 4 clamps and fixes the lever 5.

This leakage current can affect the normal operation of the circuit, leading to decreased equipment performance or malfunction. In the lighting industry, leakage current is a requirement for the design of double-ended lamps.

The first clamp body 4.1 and the second clamp body 4.2 are symmetrical about the central axis of the strip-shaped pry bar 2.

[0035] The lower ends of the first clamp body 4.1 and the second clamp body 4.2 are provided with barbed structures, which clamp and fix the lever 5. The barbed structures of the first clamp body 4.1 and the second clamp body 4.2. The barbed structures can increase the bonding force between the lever 4 and the lever 5. At the same time, when assembling the lamp head, the lever 5 can be directly inserted into the lever 4 and then fixed by the barbs, making the assembly more convenient.

[0036] The strip-shaped paddle 2 can drive the paddle pliers 4 to move left and right within the paddle slide groove 3. During movement, the paddle pliers 4 clamp the lever 5 and move it left and right. When the strip-shaped paddle 2 moves to either end of the paddle slide groove 3, it correspondingly drives the paddle pliers 4 to move the lever 5, controlling the power-off switch 6 to open or close.

The round protrusions increase the friction, making it easier for the user to exert force.

[0038] The lamp holder sleeve 1 is a cylindrical cap-shaped structure. A lamp post wiring hole is provided on one side of the cap, and a wiring sleeve 7 is provided on the wiring hole. The power line is connected to the inside of the lamp through the wiring sleeve 7, and the wiring sleeve 7 can prevent leakage current.

[0039] The lamp holder sleeve 1, strip-shaped lever 2, lever pliers 4, lever 5, and wiring sleeve 7 are all made of insulating material. The power-off switch 6 is connected to the internal circuit of the lamp tube; when the power-off switch 6 is off, the internal circuit of the lamp tube is not energized.

[0040] In this embodiment, the lever is made of non-conductive plastic, and the lever 5 of the DIP switch in contact with it is also made of non-conductive plastic. The lamp tube is installed inside the lamp fixture, and the pin is also located inside the lamp fixture. At this time, regardless of whether the lamp fixture is energized during the replacement process, there is no risk of electric shock to personnel. Furthermore, the leakage protection structure of this lamp holder is a physical structure; this method is based on physical structure control and does not affect the use of multiple lamps simultaneously.
