Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to a light guide component for LED lighting. Background Technology

[0002] LED lights are lighting fixtures with technical characteristics such as high efficiency, energy saving, long life and compact size. When used, they are usually used with light guide components to guide the light. The light guide components can disperse the light emitted by the LED lights to expand the lighting range.

[0003] Chinese patent provides a light guide component for LED lamps, publication number CN215099163U, which includes a lens and a total reflection mirror. The lens is located directly in front of the light source. A portion of the light emitted by the light source directly illuminates the lens, and another portion of the light emitted by the light source is reflected by the total reflection mirror and then illuminates the lens.

[0004] The above-mentioned device, through a total reflection mirror and a lens located directly in front of the light source, replaces the traditional method of setting a reflector cup or a lens for each chip, and has the characteristics of simple and compact structure. More importantly, the present invention can further make the light guide component an integrated structure, that is, the light transmission part and the total reflection mirror are integrated into one structure and fixedly connected to the heat sink through the connecting part, so that the entire LED lamp has the effect of waterproof and dustproof.

[0005] However, the light guide component is fixedly installed under the lamp body. After installation, its light guiding range is fixed and difficult to adjust as needed, resulting in poor flexibility of use. Furthermore, during disassembly and maintenance, the entire lamp cover needs to be disassembled, which is a rather cumbersome process. Utility Model Content

[0006] The purpose of this utility model is to provide a light guide component for LED lamps, which can effectively solve the problems in the background technology where the light guide range is fixed after installation, making it difficult to adjust as needed, resulting in poor flexibility of use, and requiring the entire lamp cover to be disassembled for disassembly and maintenance, which is a cumbersome process.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A light guide assembly for LED lighting fixtures includes a fixing rod, a mounting tube at the bottom end of the fixing rod, and a light guide mechanism on the outer ring of the mounting tube.

[0009] The light guiding mechanism includes a first light guiding reflector, a second light guiding reflector, and a light-transmitting plate. The first light guiding reflector is slidably mounted on the outer ring of the mounting tube via a sliding sleeve. An LED lamp body is mounted on the bottom end of the mounting tube via a lamp mounting base. The second light guiding reflector is mounted on the rear end of the first light guiding reflector via a connecting block and connecting bolts. A fixing plate is fixedly mounted at the connection between the fixing rod and the mounting tube. A movable rod is fixedly connected to the front end of the sliding sleeve. One end of the movable rod passes through the upper and lower ends of the fixing plate through the sliding sleeve, and the movable rod and the fixing plate are slidably connected.

[0010] The bottom ends of the first and second light guide reflectors are fixedly connected with mounting blocks. The top end of the light-transmitting plate is provided with a slot that is compatible with the mounting blocks. The light-transmitting plate is detachably installed at the bottom ends of the first and second light guide reflectors via the slot and mounting blocks. The top end of the light-transmitting plate is provided with a light guide lens that is compatible with the LED lamp body.

[0011] Preferably, a buffer spring is provided around the outer ring of the mounting tube, and the upper and lower ends of the buffer spring are fixedly connected to the opposite surfaces of the fixing plate and the sliding sleeve, respectively.

[0012] Preferably, the outer ring of the movable rod is provided with an external thread, and an adjusting nut is threadedly connected to the upper part of the outer ring of the movable rod via the external thread, the bottom end of the adjusting nut being in contact with the top surface of the fixed plate.

[0013] Preferably, the inner walls of the first light guide reflector and the second light guide reflector are mirrored, and the first light guide reflector and the second light guide reflector are combined into a cone shape. The second light guide reflector is detachably connected to the first light guide reflector through a connecting block and connecting bolts.

[0014] Preferably, the lower part of the light-transmitting plate is made of transparent material, the upper part of the light-transmitting plate is made of metal, and the bottom end of the mounting block is connected to a magnetic suction piece that is compatible with the light-transmitting plate.

[0015] Preferably, the light guide lens is arc-shaped, and the top surface of the light guide lens does not contact the LED lamp body.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This utility model, by setting up a light guide mechanism in conjunction with the LED lamp body, uses a movable rod to drive the light guide reflector plate 1, light guide reflector plate 2, and light-transmitting plate to rise and fall, changing the distance between them and the LED lamp body. This facilitates adjustment of the light guiding range and provides high flexibility in use. Furthermore, by using a buffer spring in conjunction with the light guide reflector plate 1 and the light guide reflector plate 2, when subjected to impact, the light guide reflector plate 1 slides on the mounting tube, while the buffer spring deforms in a timely and effective manner, facilitating the buffering of the impact. The non-fixed installation helps reduce the probability of damage.

[0018] The light-transmitting plate is fixed by the mounting clips. Because the mounting clips are "L"-shaped and have magnetic plates on the bottom, the light-transmitting plate can be fixed by rotating and locking, which facilitates disassembly during subsequent maintenance and reduces the cumbersome steps during maintenance and replacement. In addition, the light-transmitting plate, the second light guide reflector, and the first light guide reflector are not integrated, which makes it easy to replace them separately if damaged.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Combination Figure 1-Figure 3 A light guide assembly for LED lighting fixtures includes a fixing rod 1, a mounting tube 2 at the bottom end of the fixing rod 1, and a light guide mechanism 3 on the outer ring of the mounting tube 2.

[0026] See Figure 2 and Figure 3The light guiding mechanism 3 has a first light guiding reflector 4, a second light guiding reflector 6, and a light-transmitting plate 8. The first light guiding reflector 4 is slidably installed on the outer ring of the mounting tube 2 via a sliding sleeve 11. The bottom end of the mounting tube 2 is equipped with an LED lamp body 10 via a lamp mounting base. The second light guiding reflector 6 is installed at the rear end of the first light guiding reflector 4 via a connecting block 5 and a connecting bolt. A fixing plate 12 is fixedly installed at the connection between the fixing rod 1 and the mounting tube 2. A movable rod 13 is fixedly connected to the front end of the sliding sleeve 11. One end of the movable rod 13 passes through the upper and lower ends of the fixing plate 12 through the sliding sleeve 11, and the movable rod 13 and the fixing plate 12 are slidably connected.

[0027] The bottom ends of the light guide reflector 4 and the light guide reflector 6 are fixedly connected to the mounting block 7. The top end of the light-transmitting plate 8 is provided with a slot that is compatible with the mounting block 7. The light-transmitting plate 8 is detachably installed at the bottom ends of the light guide reflector 4 and the light guide reflector 6 through the slot and the mounting block 7. The top end of the light-transmitting plate 8 is provided with a light guide lens 9 that is compatible with the LED lamp body 10. A buffer spring 15 is provided around the outer ring of the mounting tube 2. The upper and lower ends of the buffer spring 15 are fixedly connected to the opposite surfaces of the fixed plate 12 and the sliding sleeve 11, respectively. The outer ring of the movable rod 13 is provided with an external thread, and an adjusting nut 14 is connected to the upper part of the outer ring of the movable rod 13 through the external thread. The bottom end of the adjusting nut 14 is in contact with the top surface of the fixed plate 12.

[0028] Specifically, by turning the adjusting nut 14, the movable rod 13 can be adjusted to rise and fall on the fixed plate 12, thereby moving the light guide reflector 1 4, the light guide reflector 2 6, and the light guide lens 9 on the light transmission plate 8 away from or closer to the LED lamp body 10, thus changing the light guiding range so that personnel can adjust it according to lighting needs. The light guide reflector 1 4 is slidably mounted on the mounting tube 2, so that when the light guide reflector 1 4, the light guide reflector 2 6, and the light transmission plate 8 are impacted from below, the sliding of the light guide reflector 1 4 can compress the buffer spring 15. The timely and effective deformation of the buffer spring 15 can buffer the impact force. The non-fixed connection can reduce the probability of damage from collisions.

[0029] Example 2

[0030] See Figure 3 Based on Embodiment 1, the inner walls of the first light guide reflector 4 and the second light guide reflector 6 are mirrored, and the combination of the first light guide reflector 4 and the second light guide reflector 6 is conical. The second light guide reflector 6 is detachably connected to the first light guide reflector 4 through the connecting block 5 and the connecting bolt. The lower part of the light-transmitting plate 8 is a transparent plate, and the upper part of the light-transmitting plate 8 is metal. The bottom end of the mounting block 7 is connected to a magnetic absorbing sheet that is compatible with the light-transmitting plate 8. The light guide lens 9 is arc-shaped, and the top surface of the light guide lens 9 does not contact the LED lamp body 10.

[0031] Specifically, the light-transmitting plate 8 can be fixed by rotation and snap-fit, and the magnetic suction piece set at the mounting block 7 can improve the fixing stability. The second light guide reflector plate 6 is installed on the first light guide reflector plate 4 through the connecting block 5. The second light guide reflector plate 6, the light-transmitting plate 8, and the first light guide reflector plate 4 are not integrated, so that they can be replaced individually if damaged.

[0032] In actual operation, by turning the adjusting nut 14, the movable rod 13 can be adjusted to rise and fall on the fixed plate 12, thereby moving the light guide reflector 1 4, the light guide reflector 2 6 and the light guide lens 9 on the light transmission plate 8 away from or closer to the LED lamp body 10, thereby changing the light guiding range so that personnel can adjust it according to lighting needs.

[0033] Furthermore, the light guide reflector 4 is slidably mounted on the mounting tube 2. Thus, when the light guide reflector 4, the light guide reflector 6, and the light-transmitting plate 8 are impacted from below, the sliding of the light guide reflector 4 can compress the buffer spring 15. The timely and effective deformation of the buffer spring 15 can buffer the impact force. The non-fixed connection can reduce the probability of being damaged by the impact.

[0034] Because the inner ring of the light-transmitting plate 8 is provided with a slot that is compatible with the mounting block 7, the light-transmitting plate 8 can be fixed by rotating and engaging. Furthermore, the magnetic suction piece provided at the mounting block 7 can improve the stability of the fixation and facilitate maintenance and repair efficiency.

[0035] Furthermore, the second light guide reflector 6 is mounted on the first light guide reflector 4 via the connecting block 5. The second light guide reflector 6, the light-transmitting plate 8, and the first light guide reflector 4 are not integrated into one piece, so that they can be replaced individually if damaged.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood 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 the scope of the present invention is defined by the appended claims and their equivalents.
