Description

Technical Field

[0001] The utility model belongs to the technical field of lamps and relates to a lamp with adjustable light-emitting angle. Background Art

[0002] Lamps refer to various devices used for lighting. They not only provide light sources, but also beautify the environment and create an atmosphere. According to different occasions and functions, lamps can be divided into many types, such as chandeliers, wall lamps, table lamps, downlights, corner lamps and outdoor lamps. When the lamps are lighting, the lighting angle of the lamps needs to be adjusted according to the use environment.

[0003] Existing lamp angle adjustment structures, for example, Chinese patent literature discloses a packaging device for an LED lamp [patent number: 202110912659.4; application publication number: CN113739086A], which includes a lamp holder, a refraction plate is connected to the inner side of the lamp holder, a U-shaped seat is connected to the back side of the refraction plate, a shaft is connected to the inside of the U-shaped seat, and a second gear is connected to the outside of the shaft. Through the first gear, the second gear, the fixed seat, the shaft and the U-shaped seat, the motors on both sides are turned on to drive the first gear to rotate. Under the connection between the first gear and the second gear, the second gear and the shaft inside the second gear are driven to rotate. Under the connection of the bearing, the shaft rotates along the inside of the fixed seats on both sides, thereby driving the U-shaped seat and the refraction plate to rotate, thereby realizing multi-angle refraction of light.

[0004] The packaging device of the LED lamp of this structure drives the gear to rotate through the motor, so that the refraction plate rotates, refracts the light at multiple angles, and makes the lamp head irradiate with different effects. However, in the process of use, there is a situation where the irradiation of light needs to be fixed in a certain area, and the adjustment structure of this structure is complicated and troublesome to adjust. Summary of the invention

[0005] The utility model aims to solve the above problems in the prior art and proposes a lamp with adjustable light-emitting angle, and solves the technical problem of how to make the light-emitting angle of the lamp easy to adjust and the adjustment structure simple.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a lamp with adjustable light-emitting angle, comprising a shell and a light source arranged in the shell, characterized in that it also includes a first convex lens arranged in the shell and a second convex lens arranged in the shell and can be rotatably positioned, the first convex lens is located between the light source and the second convex lens, the first convex lens is provided with a plurality of protruding first refractive parts on the light emitting side of the second convex lens, and the second convex lens is provided with a plurality of protruding second refractive parts on the light incident side of the first convex lens.

[0007] The light generated by the lamp source is refracted through the first convex lens and the second convex lens. The setting of the first refraction part and the second refraction part will change the refraction path of the lamp source light. By rotating the second convex lens, the operator can change the position of the second refraction part, thereby adjusting the path of the lamp source light and ultimately changing the irradiation direction of the light, that is, changing the light emitting angle of the lamp. The light emitting angle of the lamp can be changed by simply rotating the second convex lens. The adjustment is convenient and the adjustment structure is simple.

[0008] In the above-mentioned lamp with adjustable light-emitting angle, the center of the light-emitting side of the first convex lens has a groove, and the center of the light-entering side of the second convex lens has a convex column, the cross-sections of the groove and the convex column are both circular, and the convex column is embedded in the groove. The groove and the convex column play a positioning role, so that the axial position of the first convex lens and the second convex lens is fixed, and the circumferential direction rotates around the groove and the convex column.

[0009] In the above-mentioned lamp with adjustable light-emitting angle, the first convex lens has an annular step groove at the circumferential edge, the second convex lens has an upwardly protruding abutting ring at the circumferential edge, the top of the abutting ring is embedded in the step groove, and the first refractive part is located above the second refractive part. This structure allows the first convex lens and the second convex lens to form a better whole, and at the same time, the second refractive part will not get stuck with the first refractive part when rotating.

[0010] In the above-mentioned lamp with adjustable light-emitting angle, the first convex lens has a plurality of annular refraction rings on the side close to the light source, the refraction ring with a larger diameter is sleeved outside the refraction ring with a smaller diameter, and the refraction ring has a refraction surface arranged obliquely toward the light of the light source. The refraction ring and the refraction surface play a role of refraction, so that the light can be better gathered into the second convex lens after passing through the first convex lens, so that the light of the lamp is not dispersed, and has a better lighting effect.

[0011] In the above-mentioned lamp with adjustable light-emitting angle, a circular rotating ring is fixedly connected to the housing, a plurality of long arc-shaped rotating holes are arranged at intervals in the rotating ring, a plurality of rotating blocks are arranged on the circumferential outer side wall of the second convex lens, the second convex lens is arranged in the rotating ring, and the rotating blocks are embedded in the corresponding rotating holes. In this structure, the second convex lens can be rotated by applying a certain external force to move the rotating blocks along the rotating holes, the structure is simple, and the light-emitting angle of the lamp can be easily adjusted.

[0012] In the above-mentioned lamp with adjustable light-emitting angle, the rotating block is located at the edge of the bottom of the second convex lens, and the height of the rotating hole is greater than the height of the rotating block, so that the second convex lens can rotate smoothly without the problem of getting stuck.

[0013] Compared with the prior art, the lamp with adjustable light-emitting angle provided by the utility model has the following advantages:

[0014] 1. The light emitting angle of the lamp can be changed by applying a certain external force to rotate the second convex lens and changing the relative position of the first refractive part and the second refractive part. The adjustment is convenient and the adjustment structure is simple.

[0015] 2. The first convex lens and the second convex lens of the lamp are embedded in each other, and the integrity is stronger, ensuring that the light passes through the first convex lens and the second convex lens and then refracts out, thereby ensuring the lighting effect of the lamp.
