Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and specifically to an adjustable focus floodlight. Background Technology

[0002] Currently, floodlights on the market are mainly used for creating atmosphere and lighting. In order to improve the lighting effect of floodlights, they are usually equipped with lenses for focusing. Most existing focusing methods use a threaded connection, which changes the focal length of the lens by adjusting the stroke. With this threaded focusing method, the lamp head is easy to unscrew off the lamp tube, and the threads are easily damaged, resulting in the inability to focus.

[0003] Utility model patent CN221881248U discloses a waterproof magnetic focusing floodlight, including a lamp holder, a lamp barrel, a light source assembly, a first lens, a second lens, and a magnet. The front end of the lamp barrel has a sealing panel, and the rear end of the lamp barrel is sealed to the lamp holder. The light source assembly is fixedly installed inside the lamp barrel, and the second lens is fixedly installed at the front end of the light source assembly. The first lens is located in front of the second lens and has a magnetically conductive component. The first lens is rotatably connected to the lamp barrel through the magnetically conductive component. The magnet, rotating around the lamp barrel, can attract and drive the magnetically conductive component, thereby causing the first lens to rotate relative to the second lens around the central axis of the lamp barrel. This prior art achieves focusing through the cooperation of a magnet and a magnetically conductive component, which is costly and prone to inaccurate rotation of the first lens during focusing.

[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

[0005] To address the problems of existing technologies, this utility model proposes an adjustable-focus floodlight. The light source and a second lens are housed inside the lamp tube. A focusing ring is rotatably mounted on the lamp tube, and a first lens is housed within the focusing ring. Rotating the focusing ring causes the first lens to rotate relative to the second lens. The combination of textures on the first and second lenses alters the beam's emission angle and spot size. By providing a focusing stroke limiting groove on the focusing ring and a stroke limiting post on the lamp tube, with the stroke limiting post corresponding to the focusing stroke limiting groove, the rotation of the focusing ring relative to the second lens during focusing can be made more precise.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows: An adjustable-focus floodlight includes a lamp holder, a lamp base, a lamp tube, and a focusing ring. The lamp base is installed on the lamp holder at an adjustable angle. The lamp tube is fixed on the lamp base and contains a light source and a second lens, with the second lens and the light source corresponding to each other. The focusing ring is rotatably installed on the lamp tube and contains a first lens, with the first lens and the second lens corresponding to each other. When the focusing ring is rotated, the first lens rotates relative to the second lens. The focusing ring has a focusing stroke limiting groove, and the lamp tube has a stroke limiting post, with the stroke limiting post corresponding to the focusing stroke limiting groove.

[0007] According to the above scheme, the focusing stroke limiting groove is a waist-shaped groove, and the focusing stroke limiting groove is located on the outer wall of the focusing ring along the rotation axis. When the focusing ring is installed on the lamp tube, the focusing stroke limiting groove is located inside the lamp tube. The stroke limiting post includes a ball screw, and the stroke limiting post has a fixed end and a ball elastic end. The fixed end of the stroke limiting post is fixed to the lamp tube, and the ball elastic end of the stroke limiting post extends into the focusing stroke limiting groove.

[0008] According to the above scheme, multiple toothed grooves are arranged side by side in the focusing stroke limiting groove, and the elastic end of the ball of the stroke limiting post is engaged with the toothed groove.

[0009] According to the above scheme, the outer wall of the focusing ring is provided with a rotary stroke scale and a ring-shaped anti-slip texture. The rotary stroke scale is located on one side of the focusing stroke limiting groove, and the fixed end of the stroke limiting post is correspondingly set with the rotary stroke scale.

[0010] According to the above scheme, the lens is installed in the focusing ring through the lens fixing component. The inner wall of the focusing ring is formed with a mounting limiting groove, and the outer edge of the lens is formed with a limiting block. The limiting block and the mounting limiting groove are engaged and matched along the rotation axis.

[0011] According to the above scheme, a second waterproof rubber ring is fixed to the first end of the focusing ring, and a sealing panel is fixed to the second end of the focusing ring. The sealing panel is made of tempered glass. When the focusing ring is installed on the lamp tube, the first end of the focusing ring is located inside the lamp tube, and the second waterproof rubber ring is tightly fitted to the inner wall of the lamp tube.

[0012] According to the above scheme, a heat sink is fixed inside the lamp tube, and a light source bracket is fixed on the heat sink. The light source and lens are fixed on the light source bracket.

[0013] According to the above scheme, the lamp holder is provided with an indicator needle, and the lamp base is provided with an angle adjustment scale, with the indicator needle and the scale being set accordingly.

[0014] According to the above scheme, a breathing valve is fixed on the lamp holder, a power drive fixing component is fixed inside the lamp holder, and a power drive component is fixed on the power drive fixing component.

[0015] According to the above scheme, the end face of the lamp holder near the lamp tube is formed with an installation groove, and a waterproof rubber ring is fixed in the installation groove. When the lamp tube is fixed on the lamp holder, the waterproof rubber ring fits tightly with the end face of the lamp tube.

[0016] The beneficial effects of this utility model are: This invention features a design where the light source and lens 2 are housed inside the lamp tube. A focusing ring is rotatably mounted on the lamp tube, and lens 1 is housed within the focusing ring. Rotating the focusing ring causes lens 1 to rotate relative to lens 2.

[0019] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 5As shown, the adjustable-focus floodlight of this utility model includes a lamp holder 1, a lamp base 21, a lamp tube 31, and a focusing ring 41. The lamp base 21 is installed on the lamp holder 1 at an adjustable angle. The lamp tube 31 is fixed on the lamp base 21, and a light source 34 and a second lens 36 are provided inside the lamp tube 31, with the second lens 36 and the light source 34 being correspondingly arranged. The focusing ring 41 is rotatably installed on the lamp tube 31, and a first lens 48 is provided inside the focusing ring 41, with the first lens 48 and the second lens 36 being correspondingly arranged. When the focusing ring 41 is rotated, the first lens 48 can be rotated relative to the second lens 36. The focusing ring 41 is provided with a focusing stroke limiting groove 44, and the lamp tube 31 is provided with a stroke limiting post 32, with the stroke limiting post 32 being correspondingly arranged with the focusing stroke limiting groove 44.

[0021] This configuration places the light source 34 and lens 36 inside the lamp tube 31, and the focusing ring 41 is rotatably mounted on the lamp tube 31. Lens 48 is installed inside the focusing ring 41. When the focusing ring 41 is rotated, lens 48 rotates relative to lens 36. The combination of the patterns on lens 48 and lens 36 can change the beam's output angle and spot size. By providing a focusing stroke limiting groove 44 on the focusing ring 41 and a stroke limiting post 32 on the lamp tube 31, with the stroke limiting post 32 corresponding to the focusing stroke limiting groove 44, the rotation of the focusing ring 41 relative to lens 36 can be more precise when adjusting the focus. Furthermore, this change from the traditional threaded focusing method reduces the size of the lamp and prevents the focusing ring 41 from detaching from the lamp tube 31.

[0022] The length of the focusing stroke limiting groove 44 is consistent with the stroke of the lens 1 48 relative to the lens 2 36 to change the beam angle; after assembly, the lamp holder 21, lamp tube 31 and focusing ring 41 are coaxially arranged.

[0023] Furthermore, the focusing stroke limiting groove 44 is an oblong groove located on the outer wall of the focusing ring 41 along the rotation axis. When the focusing ring 41 is installed on the lamp tube 31, the focusing stroke limiting groove 44 is located inside the lamp tube 31. The stroke limiting post 32 includes a ball screw, and the stroke limiting post 32 has a fixed end and a ball elastic end. The ball elastic end of the stroke limiting post 32 extends into the focusing stroke limiting groove 44. In this way, the focusing stroke limiting groove 44 can limit the initial position and the maximum rotation stroke position when the focusing ring 41 drives the lens 48 to rotate.

[0024] There are two focusing stroke limiting grooves 44, which are symmetrically arranged on the left and right outer walls of the focusing ring 41, and two stroke limiting posts 32, which are symmetrically arranged on the lamp tube 31. When adjusting the focusing distance, the stroke limiting posts 32 are always located within the focusing stroke limiting grooves 44.

[0025] Furthermore, the focusing stroke limiting groove 44 is provided with multiple toothed grooves 45 arranged side by side, and the elastic end of the ball bearing of the stroke limiting post 32 engages with the toothed groove 45. This arrangement allows for a damping sensation when the focusing ring 41 is rotated, and the engagement between the elastic end of the ball bearing and the toothed groove 45 makes the position of the lens 48 more precise when the focusing ring 41 rotates; specifically, when the focusing ring 41 is slightly rotated to rotate the lens 48, the elastic end of the ball bearing moves from one toothed groove 45 to another.

[0026] With the locking engagement between the elastic end of the ball and the toothed groove 45, the focusing ring 41 will not rotate on its own when it is not under force, thus making the rotation of lens 1 48 relative to lens 2 36 to change the beam angle more stable and reliable.

[0027] Furthermore, the outer wall of the focusing ring 41 is provided with a rotational stroke scale 46 and annular anti-slip texture 47. The rotational stroke scale 46 is located on one side of the focusing stroke limiting groove 44, and the fixed end of the stroke limiting post 32 is correspondingly set with the rotational stroke scale 46. With this setting, the rotation angle of the focusing ring 41 can be rotated more accurately according to the corresponding position of the fixed end of the stroke limiting post 32 and the rotational stroke scale 46.

[0028] Furthermore, the lens 48 is mounted inside the focusing ring 41 via a lens fixing member 411. A mounting limiting groove 49 is formed on the inner wall of the focusing ring 41, and a limiting block 410 is formed on the outer edge of the lens 48. The limiting block 410 and the mounting limiting groove 49 are engaged along the rotation axis. This arrangement ensures that rotating the focusing ring 41 causes the lens 48 to rotate synchronously; and under the action of the lens fixing member 411, the lens 48 will not shift after assembly.

[0029] Preferably, there are four installation limit grooves 49 and limit blocks 410.

[0030] Furthermore, the first end of the focusing ring 41 is fixed with a waterproof rubber ring 42, and the second end of the focusing ring 41 is fixed with a sealing panel 412, which is made of tempered glass. When the focusing ring 41 is installed on the lamp tube 31, the first end of the focusing ring 41 is located inside the lamp tube 31, and the waterproof rubber ring 42 is tightly fitted against the inner wall of the lamp tube 31. This arrangement improves the waterproof performance of the focusing ring 41 and the lamp tube 31 after assembly.

[0031] Furthermore, the color of the light can be changed by replacing the encapsulation panel 412 to meet the needs of different users.

[0032] Furthermore, a heat sink 33 is fixed inside the lamp tube 31, and a light source bracket 35 is fixed on the heat sink 33. The light source 34 and the second lens 36 are fixed on the light source bracket 35. This arrangement provides better heat dissipation and thus improves the service life of the lamp.

[0033] The light source 34 is located at the center of the light source bracket 35. After assembly, the light source 34, lens 2 36 and lens 1 48 are coaxially arranged.

[0034] Furthermore, the lamp holder 1 is equipped with an indicator needle 11, and the lamp base 21 is equipped with an angle adjustment scale 22, with the indicator needle 11 and the scale 22 being correspondingly set. This arrangement allows for more precise rotation of the lamp base 21 according to the corresponding positions of the indicator needle 11 and the scale 22, thereby adjusting the illumination range of the lamp.

[0035] Furthermore, a breather valve 24 is fixed on the lamp holder 21, and a power drive fixing component 25 is fixed inside the lamp holder 21, with a power drive component fixed on the power drive fixing component 25. This arrangement allows the breather valve 24 to balance the air pressure inside and outside the lamp holder 21, thereby improving the lamp's service life.

[0036] Furthermore, the lamp holder 21 has a mounting groove 27 formed on one end face near the lamp tube 31, and a waterproof rubber ring 26 is fixed in the mounting groove 27. When the lamp tube 31 is fixed on the lamp holder 21, the waterproof rubber ring 26 fits tightly against the end face of the lamp tube 31. This design improves the waterproof performance after the lamp tube 31 and the lamp holder 21 are assembled.

[0037] The mounting groove 27 is set on the end face of the lamp holder 21, and the waterproof rubber ring 26 is installed in an embedded manner, which reduces the size of the lamp.

[0038] The waterproof rubber rings 26 and 42 provide excellent overall waterproof performance, making the lamp suitable for use under various harsh conditions.

[0039] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present utility model.
