Description

Technical Field

[0001] This utility model relates to a lighting fixture, and more particularly to a waterproof lamp. Background Technology

[0002] For some lamps, the switch or brightness needs to be controlled by a knob installed on the lamp cup. However, since the switch inside the lamp cup needs to be controlled by the knob, a channel that may allow water to enter can be created between the knob and the inside of the lamp cup. Once exposed to the external environment, water can easily enter the lamp cup and damage the lamp.

[0003] For example, a multi-functional bulb lamp with dimming function, disclosed in Chinese patent literature (publication number CN217109197U), includes a lamp head. The top of the lamp head is sequentially arranged with a lower lamp cup, a rotary switch cap, an upper lamp cup, and a bulb shell. The lower lamp cup contains a circuit board with an integrated chip. The circuit board has multiple stationary contacts arranged in a circular array. Different stationary contacts result in different resistance values ​​between the DIM pins on the integrated chip and ground. A rotary switch driver board is snapped into the bottom of the rotary switch cap, and conductive posts are fixedly connected to both sides of the bottom of the rotary switch driver board. The drawback of this patent is the lack of a waterproof structure between the rotary switch cap and the lamp cup. If used in an outdoor environment, water can easily enter the lamp cup, leading to damage to the lamp. Utility Model Content

[0004] The present invention aims to overcome the problem that existing lamps with knobs used in open-air environments are prone to water damage due to the lack of a waterproof structure. It provides a waterproof lamp that can improve the waterproof effect of lamps with knobs and prevent them from being damaged by water ingress.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model discloses a waterproof lamp, including a lamp cup, a rotating ring installed on the lamp cup, an adjustment switch installed inside the lamp cup, an adjustment part adapted to the position of the adjustment switch on the inner side of the rotating ring, a movable opening on the lamp cup at the adjustment switch, a waterproof groove between the rotating ring and the lamp, and a sealing ring installed in the waterproof groove.

[0007] The rotating ring controls the adjustment switch via an adjustment part, thereby controlling the lamp's on / off state and brightness. Since the adjustment part needs to pass through the movable opening, without a waterproof structure, rainwater can easily enter the lamp cup through the opening. This application addresses this by providing a waterproof groove and a sealing ring between the rotating ring and the lamp, preventing rainwater from entering the lamp cup and avoiding damage to the lamp.

[0008] Preferably, the inner side of the rotating ring is provided with a contact portion, the inner diameter of which gradually increases from top to bottom, and the upper part of the contact portion forms an interference fit with the lamp cup.

[0009] Preferably, the outer side of the lamp is provided with a clamping part that contacts the contact part.

[0010] Preferably, the rotating ring is provided with a vertically arranged rib, the lower end of which is located below the bottom of the rotating ring and contacts the lamp cup.

[0011] Preferably, the lamp cup is provided with a switch mark, and the raised rib is located at the switch mark.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1, as Figure 1-4 As shown, a waterproof lamp includes a lamp cup 1, a lamp shade 2, and a lamp holder 3. This waterproof lamp is mainly used in outdoor environments, especially environments where it may be exposed to rain.

[0025] A rotating ring 4 is installed on the lamp cup 1, and an adjustment switch 5 is installed inside the lamp cup 1. An adjustment part 6, adapted to the position of the adjustment switch 5, is provided on the inner side of the rotating ring 4. An movable opening 7 is also provided on the lamp cup 1 at the adjustment switch 5. A friction strip 8 is provided on the outer side of the rotating ring 4 to increase the friction between the operator's hand and the rotating ring 4. The friction strip 8 can be vertically arranged or inclined relative to the vertical direction. The rotating ring 4 includes a contact part, a rotating part, and a sealing part from top to bottom. The contact part is used to form contact with the lamp cup 1, and the inner diameter of the contact part gradually increases from top to bottom. The upper part of the contact part forms an interference fit with the lamp cup 1. When installing the rotating part, it is only necessary to put the rotating part on the outside of the lamp cup 1 from top to bottom. The friction generated by the contact part ensures that the lamp cup 1 and the rotating ring 4 will not naturally separate due to gravity. However, when the operator twists the rotating part by hand, the friction can be overcome to rotate it. The outer diameter of the rotating part is larger than that of the contact part, and a transition part in the shape of a frustum is provided between the rotating part and the contact part. The thickness of the rotating part is greater than that of the contact part to avoid damage caused by the force applied by the operator when twisting.

[0026] The adjustment switch 5 is mounted on the filament assembly 9, and a commercially available filament assembly 9 with an adjustment switch 5 is selected. Either a level adjustment or a stepless adjustment adjustment switch 5 can be used; both types of filament assemblies 9 are existing technologies. The movable opening 7 provides space for the movement of the adjustment switch 5. The adjustment part 6 includes two adjustment plates 10, forming an adjustment groove between them, and the adjustment switch 5 is located within the adjustment groove. When the rotating ring 4 rotates, the adjustment part 6 also rotates, thereby driving the adjustment switch 5 to switch and change the brightness of the lamp or control the lamp's on / off state.

[0027] A waterproof groove 11 is provided between the sealing part of the rotating ring 4 and the lamp fixture. The waterproof groove 11 is formed by the gap between the inner side of the sealing part and the outer side of the lamp fixture. Rainwater in the gap will flow to the outside of the lamp cup 1 under the action of gravity. A sealing ring 12 is installed in the waterproof groove 11. The sealing ring 12 is used to further prevent rainwater from entering between the rotating ring 4 and the lamp fixture, especially to prevent rainwater from entering the location of the movable opening 7. Therefore, the sealing part is located below the displacement rotating part.

[0028] The rotating ring 4 has a vertically arranged protruding rib 13, the lower end of which is located below the bottom of the rotating ring 4 and contacts the lamp cup 1. The contact between the protruding rib 13 and the lamp cup 1 increases the damping during rotation of the rotating ring 4, thus preventing it from rotating spontaneously without human intervention. The lamp cup 1 has a switch mark, and the protruding rib 13 is located at the switch mark. By indicating the switch mark with the protruding rib 13, the operator can determine the current brightness level of the lamp and the corresponding rotation direction of the rotating ring 4 when adjusting the lamp.

[0029] The lampshade 2 is provided with a lampshade rib 14 that fits into the lamp cup 1. Correspondingly, the lower side of the lamp cup 1 is provided with a mounting groove 15 that fits the lampshade rib 14. The opening width of the mounting groove 15 is greater than the width of the lampshade rib 14. The space between the lampshade rib 14 and the lamp cup 1 is filled with sealant. During installation, the mounting groove 15 is first filled with sealant, and then the lampshade rib 14 is inserted into the mounting groove 15 before the sealant hardens.

[0030] The lamp holder 3 is installed on the upper part of the lamp cup 1, and the lamp holder 3 and the lamp cup 1 are connected by threads. Furthermore, the lamp holder 3 is installed on the lamp base. In actual use, the upper end of the rotating ring 4 is blocked by the lamp base and will not be affected by rainwater. Therefore, only the sealing between the lower end of the rotating ring 4 and the lamp cup 1 needs to be considered.

[0031] Example 2, as Figure 5 As shown, a waterproof lamp includes a lamp cup 1, a lamp shade 2, and a lamp holder 3. This waterproof lamp is mainly used in outdoor environments, especially environments where it may be exposed to rain.

An adjustment part 6, adapted to the position of the adjustment switch 5, is provided on the inner side of the rotating ring 4. An movable opening 7 is also provided on the lamp cup 1 at the adjustment switch 5. A friction strip 8 is provided on the outer side of the rotating ring 4 to increase the friction between the operator's hand and the rotating ring 4. The friction strip 8 can be vertically arranged or inclined relative to the vertical direction. The rotating ring 4 includes a contact part, a rotating part, and a sealing part from top to bottom. The contact part is used to form contact with the lamp cup 1, and the inner diameter of the contact part gradually increases from top to bottom. The upper part of the contact part forms an interference fit with the lamp cup 1. When installing the rotating part, it is only necessary to put the rotating part on the outside of the lamp cup 1 from top to bottom. The friction generated by the contact part ensures that the lamp cup 1 and the rotating ring 4 will not naturally separate due to gravity. However, when the operator twists the rotating part by hand, it can overcome the friction and rotate it. A clamping part 16 is provided on the outer side of the lamp fixture to contact the contact part. The tightening part 16 can be used to further press down the rotating ring 4 to adjust the tightness of the fit between the rotating ring 4 and the lamp cup 1. Especially after the lamp has been used for a period of time, the contact part may wear due to friction generated during rotation. By pressing down the rotating part again, the worn contact part can continue to form an interference fit with the lamp cup 1. The outer diameter of the rotating part is larger than the outer diameter of the contact part, and a frustum-shaped transition part is provided between the rotating part and the contact part. The thickness of the rotating part is greater than that of the contact part to avoid damage caused by the force applied by the operator when tightening.

[0033] The adjustment switch 5 is mounted on the filament assembly 9, and a commercially available filament assembly 9 with an adjustment switch 5 is selected. Either a level adjustment or a stepless adjustment adjustment switch 5 can be used; both types of filament assemblies 9 are existing technologies.

[0034] A waterproof groove 11 is provided between the sealing part of the rotating ring 4 and the lamp fixture. The waterproof groove 11 is formed by the gap between the inner side of the sealing part and the outer side of the lamp fixture. Rainwater in the gap will flow to the outside of the lamp cup 1 under the action of gravity. A sealing ring 12 is installed in the waterproof groove 11. The sealing ring 12 is used to further prevent rainwater from entering between the rotating ring 4 and the lamp fixture, especially to prevent rainwater from entering the location of the movable opening 7. Therefore, the sealing part is located below the displacement rotating part.

[0035] The rotating ring 4 has a vertically arranged protruding rib 13, the lower end of which is located below the bottom of the rotating ring 4 and contacts the lamp cup 1. The contact between the protruding rib 13 and the lamp cup 1 increases the damping during rotation of the rotating ring 4, thus preventing it from rotating spontaneously without human intervention. The lamp cup 1 has a switch mark, and the protruding rib 13 is located at the switch mark. By indicating the switch mark with the protruding rib 13, the operator can determine the current brightness level of the lamp and the corresponding rotation direction of the rotating ring 4 when adjusting the lamp.
