DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-3 The utility model provides an implementation scheme: In modern LED lighting equipment, focusing mostly adopts a lens structure, and in order to adjust the focal length, it is often necessary to adjust the distance between the lens and the LED. At present, the focal length of the lens is adjusted by adjusting the distance between the lampshade 4 and the lamp holder 1. However, this method makes the connection position between the lampshade 4 and the lamp holder 1 in an active state, and then during the movement of the lens, dust will enter one side of the lamp holder 1, resulting in poor heat dissipation and lighting effect of the lamp holder 1, affecting the lighting efficiency of the LED.
[0021] In view of the above problems, the present application discloses an optical focusing device for high-efficiency LED lighting, which is composed of a lamp holder 1 and a lamp shade 4, wherein a wiring connection groove is provided on one side of the lamp holder 1, and a reflective cone groove 2 is provided on the other side of the lamp holder 1, and a plurality of LED lamp beads 3 are provided at the center of the reflective cone groove on the lamp holder 1, and a lamp shade 4 is connected to one side of the lamp holder 1, and the light emitted by the plurality of LED lamp beads 3 is enhanced by the reflection of the reflective cone groove and then emitted from one side of the lamp shade 4 to form a lighting beam;
[0022] In order to adjust the illumination beam, a zoom lens 5 is arranged on one side of the lampshade 4, and the zoom lens 5 corresponds to the lamp holder 1. A focal length adjustment component is arranged between the lampshade 4 and the lamp holder 1, and the relative distance between the zoom lens 5 and the lamp holder 1 is adjusted by the focal length adjustment component, so as to realize the change of focal length;
[0023] According to the instruction manual Figure 1-3 It can be known that the focus adjustment assembly includes an inner sleeve 6, which is sleeved outside the reflective conical groove of the lamp holder 1, and the zoom lens 5 is assembled on the end of the inner sleeve 6. A plurality of guide grooves 7 are provided on the inner sleeve 6, and a plurality of guide tracks 8 are provided on the outer ring of the reflective conical groove. The plurality of guide grooves 7 are sleeved on the plurality of guide tracks 8. A limit ring 9 is provided at the end of the inner sleeve 6 and is movably limited and installed with the lampshade 4; a sealing rubber ring 10 is provided at the notch of the reflective conical groove 2, and the sealing rubber ring 10 contacts the inner wall of the inner sleeve 6, and the inner wall of the lampshade 4 is provided with an internal thread, and an external thread is provided at the end of the lamp holder 1 to mesh with the internal thread of the lampshade 4;
[0024] In the specific implementation process, the lampshade 4 is installed outside the lamp holder 1 in a threaded connection manner. The front end of the lampshade 4 is a transparent structure for light emission. The lamp holder 1 is threadedly engaged with the lampshade 4 by rotating the end of the lamp holder 1. Under the action of the thread, the lamp holder 1 and the lampshade 4 perform axial linear motion. Due to the axial limiting effect of the limiting ring 9 and the lampshade 4, the inner sleeve 6 is kept synchronized with the lampshade 4. Furthermore, since the inner sleeve 6 and the reflective conical groove 2 are fitted together, the relative distance between the inner sleeve 6 and the reflective conical groove changes, and the distance between the zoom lens 5 located at the end of the inner sleeve 6 and the LED lamp bead 3 is changed, which plays a role in adjusting the focal length. The cooperation between the guide track 8 and the guide groove 7 plays a guiding role.
[0025] The inner sleeve 6 and the reflective conical groove are coaxially arranged, and the inner sleeve 6 and the sealing rubber ring 10 on the reflective conical groove 2 are interference fit to enhance the sealing effect, thereby preventing dust from entering between the lamp bead and the lens. The focal length can be adjusted through the cooperation between the lampshade 4 and the lamp holder 1, and the operation is also relatively convenient. The threaded cooperation between the lampshade 4 and the lamp holder 1 forms a second layer of closure, further strengthening the sealing.
[0026] As a preferred solution, further, the end of the lamp holder 1 is connected to a driving seat 11, one side of the driving seat 11 is splitly connected to a driving shaft 12, one side of the driving shaft 12 is connected to a driving motor 13, and the driving seat 11 is connected to the lamp holder 1 to support the driving motor 13, and the driving motor 13 drives the driving shaft 12 to rotate, so that the driving shaft 12 drives the gear set to engage with the movable part of the outer shell of the lamp holder 1, so that the rotating outer shell of the lamp holder 1 is threadedly engaged with the lamp cover 4, thereby moving the lamp cover 4.
[0027] As a preferred solution, further, the sealing rubber ring 10 and the inner wall of the inner sleeve 6 are interference fit, so as to improve the sealing property of the position of the inner sleeve 6.
[0028] As a preferred solution, further, the limiting ring 9 is a plate with an annular structure and its diameter is larger than the diameter of the inner sleeve 6 , and a synchronous groove 14 with an annular structure is provided inside the lampshade 4 to match the limiting ring 9 .
[0029] The synchronous groove 14 and the limiting ring 9 are movably matched. In the radial direction of the limiting groove, the synchronous groove 14 and the limiting groove are not limited, but only in the axial direction. In this way, the inner sleeve 6 can be driven to move synchronously through the limiting ring 9 during the movement of the lampshade 4.
[0030] From the above, it can be generally known that the optical focusing device of the high-efficiency LED lighting adopts an inner and outer double-layer structural design. The outer layer is threadedly connected to the lamp holder 1 through the lampshade 4 to play the role of outer layer sealing. The threaded connection between the lampshade 4 and the lamp holder 1 can also adjust the distance between the LED lamp bead 3 and the lens to achieve a zoom effect, and the inner sleeve 6 cooperates with the reflective conical groove 2 protruding on one side of the lamp holder 1 to achieve the closure of the inner layer, thereby improving the sealing effect and preventing dust from entering the focusing range of the LED lighting lamp and causing the efficiency of the LED lighting equipment to be reduced.
[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
