In this way, when the rotation angle of the lighting component needs to be adjusted, the light-emitting end of the lighting component can be rotated and also translated a certain distance accordingly, so that the initially set lighting conditions (i.e., light intensity, light spot shape, shading angle, etc.) can continue to be maintained, thereby fully improving the adaptability and adjustment ability of the lamp and improving the user's comfort and recognition.

Description

Technical Field

[0001] The invention relates to a lamp, in particular to a deep anti-glare lamp with adjustable illumination angle. Background Art

[0002] Anti-glare lamps are widely used in interior decoration and outdoor operations because they can provide floodlighting. Anti-glare lamps can not only improve the comfort of indoor users, such as exhibition hall cut-off lights used to project geometric light spots, but also provide convenience for outdoor workers, such as anti-glare ceiling lights used for construction. The main working principle of anti-glare lamps is to provide a shading angle with a reflector (or lens) inside to prevent light from directly entering the human eye. When the shading angle is greater than 30°, it can directly reduce the generation of glare.

[0003] Existing anti-glare lamps (especially deep anti-glare lamps) mostly use a fixed-axis rotation (rotation around the horizontal axis) adjustment method to adjust the illumination angle. Specifically, Figure 3 This is a schematic diagram of the internal structure of the first existing deep anti-glare lamp. The first lighting assembly 701a interferes with the first lens 702a during rotation, resulting in a small adjustment range for the illumination angle. Furthermore, during the fixed-axis rotation adjustment process, the shielding angle gradually increases, reducing or even losing the anti-glare effect. Figure 4 This is a schematic diagram of the internal structure of the second type of existing deep anti-glare lamp. In order to avoid rotation interference and increase the adjustment range, a notch is provided on the second lens 702b to ensure the rotation of the second lighting component 701b. Although this structure can increase the adjustment range of the illumination angle, when the light passes through the notch of the second lens 702b, a secondary light spot will be generated, thereby reducing the lighting capacity and anti-glare effect. At the same time, it also does not solve the technical problem of the increased shading angle during the adjustment process. In addition, the existing anti-glare lamps have technical problems such as variable and unstable light spots and inconvenient disassembly and assembly during use. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a deep anti-glare lamp with an adjustable illumination angle, which can maintain a stable shading angle during the adjustment of the illumination angle, and also has the advantages of easy assembly and disassembly and stable lighting.

[0041] According to the above structure, the deep anti-glare lamp with adjustable illumination angle proposed in the present invention mainly includes a lamp body, a movable component and a lighting component 100, wherein the lighting component 100 can link the movable component to move along the lamp body when rotating, so that when the rotation angle of the lighting component 100 needs to be adjusted, the light-emitting end of the lighting component 100 can be rotated and translated a certain distance at the same time, so that the initially set lighting conditions (i.e., light intensity, light spot shape and shading angle, etc.) can continue to be maintained, thereby fully improving the adaptability and adjustment ability of the lamp, thereby improving the user's comfort and recognition.

[0042] In some embodiments of the present invention, Figure 1 、 Figure 2 As shown, a linkage structure is provided on the lighting component 100 and the mobile component, and a guide structure is provided on the lamp body corresponding to the linkage structure.

[0045] In some embodiments of the present invention, Figure 1 、 Figure 2As shown, the lamp body includes a lamp holder 500 and a rotating ring 400. The lower end of the rotating ring 400 is rotatably set on the upper end of the lamp holder 500. A sliding mounting position 402 is set on the rotating ring 400. The moving component is slidably installed in the sliding mounting position 402. The straight rack 401 is set at the upper end of the rotating ring 400. The straight rack 401 and the sliding mounting position 402 are parallel to each other. Under this structure, the rotating ring 400 can not only provide a sliding mounting position for the moving component to meet the structural conditions of the linked translation, but also can rotate on the lamp holder 500 to drive the moving component and the lighting component 100 to rotate as a whole, providing another adjustment method to improve practicality.

[0046] In some embodiments of the present invention, Figure 1 、 Figure 2 As shown, the sliding mounting position 402 is a horizontal groove opened on the inner wall of the rotating ring 400, and the moving component is provided with a sliding foot 302 corresponding to the horizontal groove. The moving component can achieve translation along the rotating ring 400 by sliding the sliding foot 302 in the sliding mounting position 402.

[0047] In some embodiments of the present invention, Figure 1 As shown, the sliding mounting position 402 is a T-slot, and the upper and lower ends of the T-slot are symmetrically arranged. Correspondingly, the sliding foot 302 is correspondingly arranged in a T shape. Under this structure, the sliding stability of the moving component can be improved.

After the clamping block 501 is clamped into the rotary fitting recess 403, the rotating ring 400 can rotate stably on the lamp holder 500.

[0049] In some embodiments of the present invention, Figure 1 、 Figure 2 As shown, the movable component includes an outer shell 300 and an inner shell 200, the inner shell 200 is rotatably set in the outer shell 300, the sliding foot 302 is set on the outer wall of the outer shell 300, and the lighting component 100 can be detachably set in the inner shell 200. Through the assembly connection between the inner shell 200, the outer shell 300 and the lighting component 100, a practical adjustment method and a convenient use method can be formed while forming an assembled structure that is easy to disassemble and assemble.

[0050] In some embodiments of the present invention, Figure 1 、 Figure 2 As shown, a positioning hole is provided at the lower end of the inner shell 200 , and a connecting hole is provided on the outer shell 300 corresponding to the positioning hole. A rotating shaft 201 is provided in the positioning hole and the connecting hole for rotating installation of the inner shell 200 .

[0051] In some embodiments of the present invention, Figure 1 As shown, the side wall of the outer shell 300 is provided with an arc-shaped opening corresponding to the arc-shaped rack 202, so that the arc-shaped rack 202 can be detachably installed on the side wall of the inner shell 200 while being exposed on the surface of the outer shell 300, thereby facilitating user observation and use or designing a measurement structure for the rotation angle, such as setting scales and readings around the arc-shaped opening on the outer wall of the outer shell 300.

[0052] In some embodiments of the present invention, Figure 1 As shown, an opening is provided on one side of the outer shell 300 close to the rotation direction of the inner shell 200 for facilitating the disassembly and assembly of components.

[0053] In some embodiments of the present invention, Figure 1 、 Figure 2 As shown, the light-emitting end of the lighting component 100 is provided with a clearance gap to avoid interference with the lighting channel during rotation, so that while performing rotation-linked translation, it can avoid the occurrence of problems such as light spot deformation (i.e., large changes in brightness), weakening of intensity, and reduction of anti-glare performance caused by the reduction of the shading angle during the fixed-axis rotation of traditional lamps.

[0054] In some embodiments of the present invention, Figure 1 、 Figure 2 As shown, a truncated cone-shaped reflective cup is provided in the lighting channel. The reflective cup is provided with an upper opening and a lower opening that are interconnected, and the inner diameter of the upper opening is smaller than the inner diameter of the lower opening. The light-emitting end of the lighting assembly 100 is close to the upper opening to fully cooperate with the rotating linkage adjustment structure to meet the lighting usage requirements.

[0055] In some embodiments of the present invention, Figure 2 As shown, the shading angle of the reflective cup (i.e., the angle between the inner wall of the lower opening and the horizontal plane) is generally set to be above 35° (including 35°), and of course it can also be prefabricated according to the actual needs of the customer.

[0056] In some embodiments of the present invention, Figure 1 、 Figure 2 As shown, a heat dissipation fin is provided at the end of the lighting assembly 100 opposite to the light-emitting end, so as to improve the heat dissipation performance and service life of the lighting assembly 100 .

[0057] In combination with the above specific structure, it can be obtained that the deep anti-glare lamp with adjustable illumination angle proposed in the present application mainly includes three adjustment methods: the lighting component 100 rotates around the horizontal axis, the linkage shell 300 moves horizontally, and the rotating ring 400 rotates around the vertical axis. By adopting this split combined structure that is easy to disassemble and assemble, the user can drive the arc-shaped rack 202 to rotate when rotating the lighting component 100, and then drive the rotation of the circular gear 301 engaged therewith. When the circular gear 301 rotates, it will move horizontally along the straight rack 401, so that the linkage whole composed of the lighting component 100, the inner shell 200 and the outer shell 300 moves along the rotating ring 400, thereby making the light-emitting end of the lighting component 100 (compare Figure 2 、 Figure 3 or Figure 4 ) can rotate around the upper opening of the reflective cup and translate a set distance, thereby ensuring that the light emitted by the lighting assembly 100 can be stably distributed during the entire adjustment process, thereby providing stable and efficient lighting conditions (i.e. maintaining stable light intensity, light spot shape and shading angle, etc.) to fully meet the user's usage needs.
