Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a lamp. Background Art

[0002] Some lamps, such as variable beam angle lamps or correlated color temperature (CCT) selectable lamps, use switch components such as DIP switches (Dual In-line Package switches, also known as dip switches) to adjust beam angles or color temperature changes.

[0003] However, during the mechanical sliding process of the switch assembly, external water vapor easily enters the interior of the lamp housing, especially in a humid environment. Therefore, the existing lamp has a technical problem that the sliding seal needs to be improved. Utility Model Content

[0004] The inventor of the present application realizes that the switch assembly slides in the sliding groove of the housing, and the position of the switch assembly relative to the sliding groove changes constantly, which easily exposes the sliding groove to the outside, causing water vapor to enter the interior of the housing through the sliding groove, affecting the sealing and safety of the lamp. The purpose of the utility model is to provide a lamp, aiming to solve the technical problem that the sliding sealing of existing lamps needs to be improved.

[0005] The basic concept proposed by the inventor of the present application is to fix a sealing sleeve on the partial structure of the switch assembly exposed from the shell, and the sealing sleeve slides synchronously with the switch assembly and always rests against the outer surface of the shell around the sliding groove during the sliding process, thereby preventing the sliding groove from being exposed to the outside world and preventing water vapor from entering the sliding groove, thereby improving the sealing and safety of the lamp.

[0006] The present application provides a lamp, comprising:

[0007] A housing having an inner cavity and a sliding groove, wherein the sliding groove is communicated with the inner cavity;

[0008] A switch assembly is slidably disposed in the sliding groove, a part of the switch assembly is located in the inner cavity, and another part of the switch assembly is located outside the housing;

[0009] The sealing sleeve is located outside the shell, the sealing sleeve is fixedly sleeved with the switch assembly, the sealing sleeve slides synchronously with the switch assembly, and always abuts against the outer surface of the shell located around the sliding groove.

[0010] In one embodiment, the sealing sleeve includes a mounting body and a convex strip, the mounting body is fixedly sleeved on the switch assembly, one end of the convex strip is connected to the mounting body, the other end of the convex strip abuts against the outer surface of the shell, and the convex strip is arranged around the sliding groove. In this way, the convex strip covers the sliding groove in all directions at 360° to prevent water vapor from entering the sliding groove. The end of the convex strip close to the shell is a free end, which has a certain elasticity and can elastically deform to abut and fit the outer surface of the shell, thereby improving the airtightness between the convex strip and the outer surface of the shell. In addition, when the convex strip slides synchronously with the switch assembly, it sweeps the outer surface of the shell, pushing the water droplets on the outer surface of the shell away from the sliding groove, so that the surrounding surface of the sliding groove is dry.

[0011] In one embodiment, the number of the convex strips is multiple, and the multiple convex strips are spaced apart along the radial direction of the mounting body. Based on this, the multiple convex strips form a multi-level sealing protection in the direction from the center of the sliding groove to the groove wall of the sliding groove, making it difficult for external water vapor to flow into the sliding groove over the multiple convex strips, further enhancing the airtightness of the sliding groove.

[0012] In one embodiment, the switch assembly slides along the length direction of the sliding groove, the width dimension of the sealing sleeve is greater than the width dimension of the sliding groove, and the length dimension of the sealing sleeve is greater than the sum of the length dimension of the sliding groove and the maximum sliding stroke of the switch assembly. In this way, since the width dimension of the sealing sleeve is greater than the width dimension of the sliding groove, the sealing sleeve is sleeved and assembled on the switch assembly, so that the sliding groove is located between the two width sides of the sealing sleeve in the width direction, thereby preventing water vapor from entering the sliding groove in the width direction; and since the length dimension of the sealing sleeve is greater than the length dimension of the sliding groove, the sliding groove is located between the length of the sealing sleeve in the length direction, and even if the switch assembly and the sealing sleeve slide along the length direction of the sliding groove, the maximum sliding stroke of the switch assembly and the length dimension of the sliding groove are still less than the length dimension of the sealing sleeve, thereby ensuring that the sliding groove is still located between the two length ends of the sealing sleeve, thereby preventing water vapor from entering the sliding groove in the width direction.

[0013] In one embodiment, the sealing sleeve is a flexible sleeve. The sealing sleeve is made of a flexible material, and the sealing sleeve flexibly abuts against the outer surface of the shell, and can better fit the outer surface of the shell, and can still ensure sealing even if the outer surface of the shell is relatively rough.

[0014] In one embodiment, the sealing sleeve is a silicone sleeve, a felt sleeve or a plastic sleeve. The silicone sleeve and the felt sleeve have good elasticity and can be closely attached to the outer surface of the shell, and the plastic sleeve has a certain elasticity and can also be elastically attached to the outer surface of the shell, thereby ensuring a sealed fit between the sealing sleeve and the outer surface of the shell.

[0015] In one of the embodiments, the sealing sleeve is integrally formed with the switch assembly, which improves the assembly consistency between the sealing sleeve and the switch assembly and avoids assembly errors. At the same time, the integral molding improves the integrity of the sealing sleeve and the switch assembly, improves the airtightness between the sealing sleeve and the switch assembly, avoids the formation of gaps between the sealing sleeve and the switch assembly due to loose connection, and prevents water vapor from entering the sliding groove through the gaps between the sealing sleeve and the switch assembly.

[0016] In one embodiment, the switch assembly includes an operating part and a switch cover, the operating part is slidably disposed in the sliding groove, the end of the operating part exposed from the shell is connected to the inner side of the switch cover, an isolation gap is provided between the switch cover and the outer surface of the shell, the sealing sleeve is sleeved with the operating part, the sealing sleeve is located between the switch cover and the outer surface of the shell, and seals the isolation gap. In this way, the switch cover covers the end of the operating part to prevent water vapor from entering the sliding groove along the outer wall of the operating part; the switch cover is isolated from the outer surface of the shell to prevent sliding wear between the switch cover and the outer surface of the shell; the sealing sleeve seals the isolation gap to prevent water vapor from entering the sliding groove through the isolation gap.

[0017] In one embodiment, the inner side of the switch cover has a mounting hole; wherein the end of the operating part is snapped and / or bonded in the mounting hole. The end of the operating part is wrapped by the hole wall of the mounting hole, so that the end of the operating part is sealed, and water vapor is further prevented from entering the sliding groove along the outer wall of the operating part. The operating part is snapped and / or bonded and fixed in the mounting hole, which enhances the airtightness of the connection between the operating part and the switch cover.

[0018] In one of the embodiments, the sealing sleeve is sealingly fitted and fixed to the inner wall of the switch cover body, thereby increasing the contact area between the sealing sleeve and the switch cover body, avoiding the formation of a gap between the sealing sleeve and the inner wall of the switch cover body, which would cause water vapor to enter between the sealing sleeve and the inner wall of the switch cover body, and then preventing the water vapor from flowing from the inner wall of the switch cover body to the operating part and the sliding groove.

[0019] In one embodiment, the sealing sleeve body is sleeved with the operating part in an interference fit. Based on this, the interference fit can increase the sleeve airtightness between the sealing sleeve body and the operating part, making it difficult for external water vapor to flow along the outer wall of the operating part toward the sliding groove.

[0020] In one embodiment, the lamp further includes a circuit board, the switch assembly further includes a trigger part, the circuit board is mounted in the inner cavity, the trigger part is mounted on the circuit board, and the operating part is electrically connected to the trigger part. In this way, the operating part slides relative to the trigger part and contacts different positions of the trigger part, so that the trigger part outputs different electrical signals, and then the working state of the lamp such as the beam angle or color temperature is adjusted through the circuit board.

[0021] The beneficial effects of the lamp provided by the utility model are as follows: the sealing sleeve fixes the switch assembly exposed from the part of the shell structure, so that it can slide synchronously with the switch assembly, and during the sliding process, the sealing sleeve always abuts against the outer surface of the shell around the sliding groove, thereby preventing the sliding groove from being exposed to the outside and preventing water vapor from entering the sliding groove, thereby improving the sealing and use safety of the lamp.

[0038] Combination Figure 1 and Figure 2The lamp provided in the present application includes a housing 100, a switch assembly 200 and a sealing sleeve 300. The housing 100 has an inner cavity 101 and a sliding groove 102, and the sliding groove 102 is connected to the inner cavity 101. The switch assembly 200 is slidably arranged in the sliding groove 102, a part of the structure of the switch assembly 200 is located in the inner cavity 101, and another part of the structure is located outside the housing 100. The sealing sleeve 300 is located outside the housing 100, and the sealing sleeve 300 is fixedly sleeved with the switch assembly 200. The sealing sleeve 300 slides synchronously with the switch assembly 200 and always abuts against the outer surface of the housing 100 located around the sliding groove 102.

[0039] For example, combined with Figure 3 , the switch assembly 200 is located at the bottom of the sliding groove 102. At this time, the sealing sleeve 300 surrounds the sliding groove 102 and abuts against the outer surface of the housing 100 located around the sliding groove 102 to prevent water vapor from entering the sliding groove 102. Figure 4 , the switch assembly 200 slides along the length direction X of the sliding groove 102, and the switch assembly 200 slides to the top of the sliding groove 102. At this time, the sealing sleeve 300 still surrounds the sliding groove 102 and abuts against the outer surface of the housing 100 located around the sliding groove 102 to prevent water vapor from entering the sliding groove 102. In this way, during the sliding process of the switch assembly 200 in the sliding groove 102, the switch assembly 200 slides to any position of the sliding groove 102, and the sealing sleeve 300 always abuts against the outer surface of the housing 100 located around the sliding groove 102 to prevent water vapor from entering the sliding groove 102.

[0040] It can be seen that the sealing sleeve 300 fixes the switch assembly 200 that is exposed outside the shell 100, and slides synchronously with the switch assembly 200. During the sliding process, it always rests against the outer surface of the shell 100 around the sliding groove 102, preventing the sliding groove 102 from being exposed to the outside world and preventing water vapor from entering the sliding groove 102, thereby improving the sealing and safety of the lamp.

[0041] In some embodiments, in combination Figure 3 and Figure 4The sealing sleeve 300 includes a mounting body 310 and a convex strip 320. The mounting body 310 is fixedly sleeved on the switch assembly 200. One end of the convex strip 320 is connected to the mounting body 310. The other end of the convex strip 320 abuts against the outer surface of the housing 100. The convex strip 320 surrounds the sliding groove 102. In this way, the convex strip 320 can cover the sliding groove 102 in all directions at 360° to prevent water vapor from entering the sliding groove 102. The end of the convex strip 320 close to the housing 100 is a free end, which has a certain elasticity and can be elastically deformed to abut and fit the outer surface of the housing 100, especially during the sliding process, it can be tightly abutted against the curved surfaces of different positions, shapes and sizes of the housing 100, thereby improving the airtightness between the convex strip 320 and the outer surface of the housing 100. Furthermore, when the convex strip 320 slides synchronously with the switch assembly 200 , it sweeps the outer surface of the housing 100 , pushing water droplets on the outer surface of the housing 100 away from the sliding groove 102 , so that the surrounding surface of the sliding groove 102 is dry.

[0042] In one embodiment, in combination Figure 3 and Figure 4 The number of the convex strips 320 is multiple, and the multiple convex strips 320 are spaced apart along the radial direction of the mounting body 310. Based on this, the multiple convex strips 320 form a multi-level sealing protection in the direction from the center of the sliding groove 102 to the groove wall of the sliding groove 102, making it difficult for external water vapor to flow into the sliding groove 102 over the multiple convex strips 320, further enhancing the airtightness of the sliding groove 102.

[0043] Specifically, combined Figure 3 and Figure 4 The number of the convex strips 320 is three, and the three convex strips 320 are arranged on the outer periphery of the sliding groove 102 from the inside to the outside, forming a three-level sealing protection, so that it is difficult for water vapor to pass through the three-level sealing protection and enter the sliding groove 102. It can be understood that in other embodiments of the present application, the number of the convex strips 320 can be two, four, or five, etc., which will not be repeated here.

[0044] In some embodiments, in combination Figure 5 , the switch assembly 200 slides along the length direction X of the sliding groove 102, and the width dimension W2 of the sealing sleeve 300 is greater than the width dimension W1 of the sliding groove 102, that is, W2>W1, so that the sealing sleeve 300 is sleeved and assembled on the switch assembly 200, and the sliding groove 102 can be located between the width sides of the sealing sleeve 300 in the width direction Y, so as to prevent water vapor from entering the sliding groove 102 along the width direction Y. Figures 3 to 5The length dimension L2 of the sealing sleeve 300 is greater than the sum of the length dimension L1 of the sliding groove 102 and the maximum sliding stroke S of the switch assembly 200, that is, L2>(L1+S), so that the sliding groove 102 is located between the lengths of the sealing sleeve 300 in the length direction X, and the switch assembly 200 and the sealing sleeve 300 slide along the length direction X of the sliding groove 102, and the sliding groove 102 is always located between the lengths of the sealing sleeve 300, thereby preventing water vapor from entering the sliding groove 102 along the width direction Y.

[0045] In some embodiments, in combination Figure 5 The sealing sleeve 300 is a flexible sleeve. The sealing sleeve 300 is made of a flexible material, and the sealing sleeve 300 flexibly abuts against the outer surface of the housing 100, and can better fit the outer surface of the housing 100. Even if the outer surface of the housing 100 is relatively rough or uneven, it can still ensure a sealed fit.

[0046] In some embodiments, in combination Figure 5 The sealing sleeve 300 is a silicone sleeve, a felt sleeve or a plastic sleeve. The silicone sleeve and the felt sleeve have good elasticity and can be closely attached to the outer surface of the housing 100. The plastic sleeve has a certain elasticity and can also be elastically attached to the outer surface of the housing 100 to ensure the sealing fit between the sealing sleeve 300 and the outer surface of the housing 100. At the same time, the plastic sleeve has good rigidity and strength and can well scrape off water droplets around the sliding groove 102 during the sliding process.

[0047] In some embodiments, in combination Figure 3 and Figure 4 The sealing sleeve 300 is integrally formed with the switch assembly 200, which improves the assembly consistency between the sealing sleeve 300 and the switch assembly 200 and avoids assembly errors. At the same time, the integral molding improves the integrity of the sealing sleeve 300 and the switch assembly 200, improves the airtightness between the sealing sleeve 300 and the switch assembly 200, avoids the formation of gaps between the sealing sleeve 300 and the switch assembly 200 due to loose connection, and prevents water vapor from entering the sliding groove 102 through the gap between the sealing sleeve 300 and the switch assembly 200.

[0048] In some embodiments, in combination Figure 3 and Figure 4The switch assembly 200 includes an operating part 210 and a switch cover 220. The operating part 210 is slidably disposed in the sliding groove 102. The end of the operating part 210 exposed from the housing 100 is connected to the inner side of the switch cover 220. The switch cover 220 covers the end of the operating part 210 to prevent water vapor from entering the sliding groove 102 along the outer wall of the operating part 210. An isolation gap 201 is provided between the switch cover 220 and the outer surface of the housing 100 to prevent sliding wear between the switch cover 220 and the outer surface of the housing 100. The sealing sleeve 300 is sleeved on the operating part 210. The sealing sleeve 300 is located between the switch cover 220 and the outer surface of the housing 100 and seals the isolation gap 201 to prevent water vapor from entering the sliding groove 102 through the isolation gap 201.

[0049] In one embodiment, in combination Figure 3 , the inner side of the switch cover 220 has a mounting hole 221. The end of the operating part 210 is snapped into the mounting hole 221, or the end of the operating part 210 is snapped into the mounting hole 221, or the end of the operating part 210 is snapped into the mounting hole 221 and bonded into the mounting hole 221 at the same time. In this way, the end of the operating part 210 is wrapped by the hole wall of the mounting hole 221, so that the end of the operating part 210 is sealed, and water vapor is further prevented from entering the sliding groove 102 along the outer wall of the operating part 210. The snap-fit ​​and / or bonding connection method can enhance the air tightness of the connection between the operating part 210 and the switch cover 220.

[0050] Specifically, combined Figure 3 The sealing sleeve 300 is sealed and fixed to the inner wall of the switch cover 220, increasing the contact area and sealing area between the sealing sleeve 300 and the switch cover 220, avoiding the formation of a gap between the sealing sleeve 300 and the inner wall of the switch cover 220, which would cause water vapor to enter between the sealing sleeve 300 and the inner wall of the switch cover 220, and then preventing the water vapor from flowing from the inner wall of the switch cover 220 to the operating part 210 and the sliding groove 102.

[0051] Specifically, the sealing sleeve 300 is sleeved with the operating part 210 by interference fit. Based on this, the interference fit can increase the sleeve airtightness between the sealing sleeve 300 and the operating part 210, prevent water vapor from entering the sliding groove 102 through the contact position between the sealing sleeve 300 and the operating part 210, and make it difficult for external water vapor to flow along the outer wall of the operating part 210 toward the sliding groove 102.

[0053] In some embodiments, the switch assembly 200 may be a DIP switch.
