Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, and in particular to an ultraviolet lamp. Background Technology

[0002] Currently, VU lamps on the market are diffused, free-emitting disinfection lamps that cannot freely select the beam or precisely control the light. Furthermore, current UV lamps also pose a risk of harm to the human body due to their inability to effectively protect against ultraviolet rays.

[0003] In addition, existing ultraviolet lamps lack structural flexibility and cannot adequately meet users' needs.

[0004] Therefore, there is an urgent need to provide an ultraviolet lamp to overcome the above-mentioned defects. Utility Model Content

[0005] The main purpose of this utility model is to provide an ultraviolet lamp with advantages such as high safety factor, good light control effect and better rational structure.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An ultraviolet lamp includes: a base mechanism with a support arm protruding from one side, and a lamp body mechanism that is angle-adjustably installed at the other end of the support arm; the lamp body mechanism includes: a lamp housing, a UV light source, an isolation plate, a reflector cup, a protective glass, a focusing tube with a light-absorbing layer, and a fixing assembly sequentially installed in the lamp housing; the focusing tube passes through the fixing assembly and is fixed to the lamp housing by the fixing assembly, and the fixing assembly is detachably snapped into the lamp housing.

[0008] Preferably, the UV light source emits light in the wavelength range of 380-390nm.

[0009] The focusing tube is a hollow cylinder, and one end of the focusing tube protrudes outward with a snap-fit ​​part, which is snapped and limited by the first snap-fit ​​ring of the fixing component.

[0010] Preferably, the fixing component includes: a first snap-fit ​​ring, a fixing body with one side abutting against one side of the first snap-fit ​​ring, and a snap-fit ​​elastic member with one end snapped and fixed to the side of the fixing body and the other end snapped by the first snap-fit ​​ring and extending toward the UV light source.

[0011] Preferably, the snap-fit ​​elastic element is bent in the middle, and each snap-fit ​​elastic element has a trapezoidal structure.

[0012] Preferably, the side of the fixing body is formed with a buckle structure for snapping and fixing the snapping elastic member, the buckle structure forms a snapping and fixing channel, and the snapping elastic member snaps into the snapping and fixing channel.

[0013] Preferably, the buckle structure includes: a first groove formed on the side of the fixing body, and a first / second abutting positioning buckle plate protruding from the first groove and having a gap, wherein a locking groove is formed on one side of the first abutting positioning buckle plate, and the gap and the locking groove form the locking fixing channel.

[0014] Preferably, the abutting positioning buckle plate protrudes from the first groove and is located below the engaging groove to support and abut the engaging elastic member.

[0015] Preferably, a limiting spring piece located within the base mechanism is connected to one end of the support arm that is inserted into the base mechanism.

[0016] Preferably, a notch is formed on the lamp housing, and the support arm is inserted into the lamp housing through the notch to rotate 0-90° around the connection point with the lamp body.

[0017] This utility model discloses an ultraviolet lamp. Within the lamp housing, a UV light source, an isolation plate, a reflector cup, a protective glass, and a focusing tube are sequentially arranged. The UV light source, after being isolated by the isolation plate, is reflected and focused onto the target surface by the reflector cup. Then, after passing through the protective glass, the focusing tube absorbs the secondary light outside the target surface. This allows the product to achieve beam selection and better light control, while also improving the safety factor during use. Furthermore, the lamp body is angle-adjustably connected to the support arm, making the product more flexible in application and demonstrating a well-designed and rational structural configuration.

[0030] Please see Figures 1 to 4An ultraviolet lamp according to this embodiment includes: a base mechanism 1 with a support arm 2 protruding from one side, and a lamp body mechanism 3 that is angle-adjustably installed at the other end of the support arm 2.

[0031] In a preferred embodiment, the base mechanism 1 includes: a base housing with an internal cavity; a control circuit installed inside the base housing; a through hole formed on one end face of the base housing to conduct through the cavity; one end of the support arm 2 passes through the through hole and is connected to a limiting spring 11; the limiting spring 11 connects to the base housing 1; the limiting spring 11 is movably disposed in the cavity and rotates the lamp body mechanism 3; the support arm 2 and the limiting spring 11 are linked together, enabling the lamp body mechanism 3 to achieve 360° rotation.

[0032] The main body of the lamp 21 includes: a lamp housing 31, a UV light source 32, an isolation plate 33, a reflector cup 34, a protective glass 35, and a focusing tube 36 sequentially installed within the lamp housing 31, and a fixing component 37 sleeved on the outer periphery of the focusing tube 36 and snapped into the lamp housing 21. Specifically, the UV light source 31 emits light with a wavelength range of 380-390nm. The ultraviolet light emitted by the UV light source 32 is isolated by the isolation plate 33 and then emitted by the reflector cup 34. The protective glass 35 abuts against the opening at one end of the reflector cup 34, allowing the UV light to be projected out effectively. The protective glass 35 also helps to improve the dustproof and waterproof performance of the product. The focusing tube 36 is a hollow cylinder, and one end of the focusing tube 36 protrudes outward with a snap-fit ​​part 361. The snap-fit ​​part 361 is snapped and limited by the first snap-fit ​​ring 371 of the fixing component 37. More specifically, the focusing tube 36 protrudes from the lamp housing 31, and the focusing tube 36 is made of metal. Its outer layer is provided with a light-absorbing layer that absorbs the secondary light spot emitted by the reflector cup 34, thereby reducing the range of the secondary light spot from L (the original range of the secondary light spot emitted by the reflector cup 34) to L1 (the current range of the secondary light spot). This provides better protection during use, effectively preventing ultraviolet leakage and achieving precise light control. It should be noted that this light-absorbing layer is made of existing materials, and therefore will not be described in detail here.

[0033] Further, the fixing component 37 includes: a first snap-fit ​​ring 371, a fixing body 372 with one side abutting against the first snap-fit ​​ring 371, and a snap-fit ​​elastic member 373 with one end snapped and fixed to the side of the fixing body 372 and the other end snapped by the first snap-fit ​​ring 371 and extending toward the UV light source 32. The snap-fit ​​elastic member 373 is bent in the middle, and each snap-fit ​​elastic member 373 has a trapezoidal structure. A buckle structure for snapping and fixing the snap-fit ​​elastic member 373 is formed on the side of the fixing body 372. The snap-fit ​​fixing channel is provided, and the snap-fit ​​elastic element 373 is snapped onto the snap-fit ​​fixing channel. The snap-fit ​​structure includes: a first groove a1 formed on the side of the fixing body, and a first a2 / second a3 abutting positioning buckle plate protruding from the first groove a1 and having a gap. One side of the first abutting positioning buckle plate a2 has a snap-fit ​​groove formed concavely. The gap and the snap-fit ​​groove form the snap-fit ​​fixing channel. The second abutting positioning buckle plate a3 protrudes from the first groove a1 and is located below the snap-fit ​​groove to support and abut the snap-fit ​​elastic element 373. In use, the first snap ring 371 is abutted against the opening at one end of the fixing body 372. After the snap-fit ​​elastic member 373 is abutted and positioned by the abutting positioning buckle plate a2 and the abutting positioning buckle plate a3, it is snapped into the concave groove on the side of the first snap ring 371 and fixed into the lamp housing 31, thereby fixing the spotlight tube 36. This makes it easy to disassemble and assemble, and facilitates the replacement and disassembly of the spotlight tube 36 accessories.

[0034] Furthermore, one end of the lamp housing 31 is formed with a notch, through which the support arm is inserted into the lamp housing 31, and the lamp housing 31 can rotate around the support arm 2 within the notch, with a rotation angle of 0-90°. Specifically, the end of the support arm 2 that is inserted into the lamp housing 31 is formed with a snap-fit ​​hole, and a rotating shaft is formed on the fixed base inside the lamp housing 31 to snap into the snap-fit ​​hole, and a rotating positioning piece is formed within the snap-fit ​​hole and sleeved by the rotating shaft. When the support arm rotates, it rotates around the rotating shaft, and the rotating positioning piece achieves the effect of angle positioning.

[0035] As can be seen from the above description, this utility model, through its reasonable structural design, enables the product to be used more flexibly, has a good structural design, and has the advantages of higher light control accuracy and higher safety factor.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
