DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0029] See also Figure 1-Figure 9In an embodiment of the present invention, a wide-angle spotlight with adjustable light output angle includes a lamp holder 1 and a shell 2 adapted to the lamp holder 1, wherein the shell 2 includes a cylindrical portion and a conical portion respectively located inside and outside the lamp holder 1, the cylindrical portion is adapted to the lamp holder 1, and a reflector 3 is provided on the inner wall of the conical portion; the wide-angle spotlight with adjustable light output angle further includes: a lamp body 4, which is movably arranged in the cylindrical portion and connected to a rotation adjustment mechanism installed at the center of the cylindrical portion, and the rotation adjustment mechanism can drive the lamp body 4 It moves axially along the cylindrical portion in the reflector 3 to change the light output angle; an electrical connection mechanism is arranged in the cylindrical portion and connected to the lamp body 4, and the electrical connection mechanism cooperates with a static contact 7 arranged at the top of the lamp holder 1 and connected to a power source. The cylindrical portion is also provided with two groups of elastic locking mechanisms that cooperate with the lamp holder 1. The elastic locking mechanism is triggered after the shell 2 enters the lamp holder 1, and can drive the electrical connection mechanism to complete the electrical connection with the static contact 7 to energize the lamp body 4.

[0030] Specifically, in actual use, the lamp holder 1 is fixedly installed on the top of the wall or the wall. After the lamp body 4 is powered on, it is reflected by the reflector 3 to achieve irradiation with a specific light output angle. When the light output angle needs to be adjusted, the debugging personnel manipulate the rotation adjustment mechanism to move forward or reversely, so that the rotation adjustment mechanism drives the lamp body 4 to move along the axial direction of the cylindrical portion in the reflector 3. When the lamp beads at the end of the lamp body 4 move toward the outside of the reflector 3, the light output angle increases, otherwise, the light output angle decreases. During assembly, the staff pushes the shell 2 into the lamp holder 1. In the latter part of the stroke of the shell 2, the elastic locking mechanism will be triggered, so that the The shell 2 is connected to the lamp holder 1, and at the same time, the electrical connection mechanism is triggered to complete the electrical connection with the static contact 7, so that the lamp body 4 is connected to the power supply, and the lamp beads at the end of the lamp body 4 are lit to realize the lighting function. Then, the light output angle can be adjusted according to the lighting needs; when the lamp body 4 fails, the staff first operates the elastic locking mechanism to release the locking state between the shell 2 and the lamp holder 1 to remove the shell 2 from the lamp holder 1, thereby realizing the function of easy disassembly and assembly of the spotlight. When the lamp body 4 fails, there is no need to remove it together with the lamp holder 1. Generally speaking, the lamp holder 1 is connected to the wall top or wall through a screw, and the disassembly process is relatively complicated.

[0031] It should be supplemented that, according to the conventional configuration of a spotlight, the spotlight further includes a lens, and the lens, the lamp bead 4 and the housing 2 are integrally configured for assembly and disassembly.

[0032] Please refer again Figure 7 , Figure 8as well as Fig. 9 A through hole 201 is provided at the center of the cylindrical portion, and the rotation adjustment mechanism includes a sleeve 5 arranged in the through hole 201. The outer wall of the sleeve 5 is provided with an external thread, and the inner wall of the through hole 201 is provided with an internal thread, and the two sections of the thread are engaged with each other, and the lamp body 4 is rotatably connected to the sleeve 5.

[0033] Specifically, when debugging the light output angle, the staff can rotate the kit 5 forward or reversely through the portion of the kit 5 that leaks out of the through hole 201. Then, under the cooperation of the threads on the outer wall of the kit 5 and the inner wall of the through hole 201, the kit 5 can be screwed out (screwed in) to the outside (inside) of the through hole 201. Accordingly, the position of the lamp bead at the end of the lamp body 4 in the reflector 3 changes, that is, the light output angle after power-on increases (decreases).

[0034] The electrical connection mechanism includes a moving contact 6 slidably disposed in the through hole 201 and adapted to the static contact 7, and a wire 8 disposed in the through hole 201, wherein the length of the wire 8 is greater than the distance between the moving contact 6 and the lamp body 4 when the lamp body 4 is in a powered state and the light output angle reaches a maximum value. Both ends of the wire 8 are electrically and fixedly connected to the moving contact 6 and the lamp body 4, respectively, and the moving contact 6 cooperates with the elastic locking mechanism through a follower structure.

[0035] The two wires in the loop are integrated in the wire 8, so the lamp body and the moving contact 6 are provided with two contact points to achieve loop closure; one end of the wire 8 is fixed to the lamp body 4, and the other end is fixed to the moving contact 6, so only one end of the moving contact 6 needs to be provided with a contact point;

[0036] The wire 8 is a double-strand wire, and the two wires 8 are integrated together at one end corresponding to the moving contact 6 to form an integrated moving contact 6 .

[0037] It should be noted that the maximum value mentioned above is the light output angle formed by the reflection processing of the reflector 3 when the kit 5 is at the end of the stroke rotated toward the outside of the through hole 201 and the moving contact 6 and the static contact 7 are connected.

[0038] Furthermore, when adjusting the light output angle, the staff will screw the kit 5 out or in the through hole 201, and accordingly, the kit 5 will drive the lamp body 4 to move along the axial direction of the cylindrical portion. Therefore, the length of the wire 8 should have a margin; secondly, the purpose of the rotational connection between the kit 5 and the lamp body 4 is that when adjusting the light output angle, the kit 5 will rotate. If the lamp body 4 and the kit 5 are fixedly connected, the lamp body 4 will rotate with the kit 5. If the kit 5 rotates too many times, the wire 8 will be twisted, and the connection between the wire 8 and the lamp body 4 and the moving contact 6 may become loose or even broken. Therefore, the rotational connection between the lamp body 4 and the kit 5 can effectively protect the wire 8 when adjusting the light output angle.

[0039] Specifically, a circle of flanges may be provided on the outer periphery of the lamp body 4, and a circle of grooves matched with the flanges may be provided on the inner wall of the sleeve 5, and the lamp body 4 and the sleeve 5 may be rotatably connected by the rotational cooperation between the flanges and the grooves.

[0040] It should be emphasized that the two ends of the wire 8 are respectively fixed to the moving contact 6 and the lamp body 4, and the wire 8 is hard and spirally arranged to have a certain elasticity to form a spring conductive wire. The physical properties are similar to those of a cylindrical spring, which cannot be twisted but can be elastically stretched; thus, when the kit 5 is rotated, the wire 8 can have a certain supporting effect on the lamp body 4, and since the lamp body 4 and the kit 5 are rotatably connected, the lamp body 4 will not rotate, thereby avoiding the problem of loose connection between the wire 8 and the lamp body 4 and the moving contact 6 due to the twisting of the wire 8.

[0041] Please refer again Figure 4 , Figure 5 as well as Fig. 9The elastic locking mechanism includes a transverse moving assembly provided at one end of the columnar portion away from the conical portion and an elastic supporting assembly connected to the transverse moving assembly. The elastic supporting assembly is provided along the radial direction of the columnar portion. The transverse moving assembly can move along the radial direction of the columnar portion and penetrate the lamp holder 1 through the elastic supporting assembly, and at the same time, the follower structure drives the moving contact 6 to perform the docking action with the static contact 7. A sliding groove 202 is provided in the radial direction of the columnar portion. The transverse moving assembly includes a slider 9 slidably engaged in the sliding groove 202. A roller 15 is installed on the slider 9. The roller 15 cooperates with a limit block 14 fixed on the inner wall of the lamp holder 1. The limit block 14 is provided in the shape of a right triangle. An extension portion 901 is formed at one end of the slider 9 away from the moving contact 6, and a through opening adapted to the extension portion 901 is provided on the cylindrical portion and the housing 2. When the roller 15 passes through the inclined surface 1401 on the limit block 14, the slider 9 will be prompted to drive the moving contact 6 to retract into the through hole 201 through the follower structure.

[0042] The elastic support assembly includes a guide rod 10 fixed in the slide groove 202 and a cylindrical spring 11 sleeved on the outer periphery of the guide rod 10. The guide rod 10 passes through a protrusion 902 formed on the slider 9 and is slidably connected to the protrusion 902. One end of the cylindrical spring 11 is connected to the inner wall of the slide groove 202, and the other end is connected to the protrusion 902.

[0043] When assembling the housing 2 and the lamp holder 1, the extension portion 901 is first pushed into the interior of the conical portion, and then the housing 2 is pushed into the interior of the lamp holder 1. After the roller 15 contacts the inclined surface 1401, the roller 15 drives the slider 9 to give way. At this time, the slider 9 slides in the slide groove 202 close to the moving contact 6, and drives the moving contact 6 to retract into the through hole 201 through the follower mechanism. Accordingly, the cylindrical spring 11 is compressed. After the roller 15 is disengaged from the inclined surface 1401, the cylindrical spring 11 is compressed. 1 rebounds, so that the slider 9 slides away from the moving contact 6 in the slide groove 202, and the extension portion 901 penetrates the lamp holder 1 through the through opening, so that the fastening connection between the lamp holder 1 and the housing 2 is achieved; it should be noted that when performing the above operation, in order to ensure that the roller 15 and the limit block 14 can be smoothly matched, a guide groove can be provided on the inner wall of the lamp holder 1, and a guide block adapted to the guide groove can be fixedly provided on the outer wall of the columnar portion, so that when the housing 2 and the lamp holder 1 are assembled, the guide block can be aligned with the guide groove.

[0044] When the shell 2 needs to be disassembled, the staff presses the extension portion 901 toward the interior of the lamp holder 1 (with the help of a specific tool) until the roller 15 is misaligned with the limit block 14, and then the fastened connection between the shell 2 and the lamp holder 1 is released, and then the lamp holder 1 can be pulled out of the shell 2; it should also be noted that after the extension portion 901 is pressed toward the interior of the lamp holder 1, the cylindrical spring 11 is compressed. At this time, in order to prevent the extension portion 901 from rebounding, the staff needs to keep pressing the extension portion 901 so that the shell 2 can be smoothly pulled out of the lamp holder 1, which makes the operation more troublesome and increases the difficulty of disassembly. In this regard, a plurality of sets of elastic telescopic rods 16 are provided on the top wall of the lamp holder 1. It includes a guide cylinder fixed on the top wall of the lamp holder 1 and a push rod slidably fitted with the guide cylinder, and a cylindrical spring 11 is connected between the push rod and the inner wall of the guide cylinder. During assembly, as the shell 2 is pushed in, the push rod will be prompted to retract into the guide cylinder and compress the cylindrical spring 11 in the guide cylinder. When the shell 2 is removed, after the extension part 901 is pressed, the cylindrical spring 11 in the guide cylinder can rebound, so that the push rod provides a certain thrust to the shell 2, so that the extension part 901 and the through opening can be misaligned, so that during the removal process, after the extension part 901 is pressed, the staff can directly pull the shell 2 out of the lamp holder 1 without keeping the extension part 901 pressed, thereby simplifying the removal process of the shell 2.

[0045] The follower structure includes a driven arm 13 fixedly connected to the moving contact 6 and inclined, and two connecting arms 12 fixedly mounted on the slider 9 and respectively located on both sides of the driven arm 13. A column is fixedly provided between the two connecting arms 12, and a through groove adapted to the column is provided on the driven arm 13 along its length direction. The column passes through the through groove and is slidably connected to the connecting arm 12.

[0046] When the roller 15 rolls along the inclined surface 1401, the slider 9 gives way, that is, the column is driven by the two connecting arms 12 to move closer to the moving contact 6. At this time, the column will slide with the driven arm 13 through the through groove, causing the driven arm 13 to drive the moving contact 6 to retract toward the inside of the through hole 201. When the roller 15 is disengaged from the inclined surface 1401, the cylindrical spring 11 rebounds quickly, and the column slides with the driven arm 13 again, so that the moving contact 6 slides quickly toward the outside of the through hole 201 and docks with the static contact 7, so that the lamp body 4 is powered on.

[0047] The connection between the moving contact 6 and the stationary contact 7 is a plug-in connection. When the housing 2 is removed, the moving contact 6 is pulled out from the stationary contact 7 .

[0048] Due to the arrangement of the driven arm 13 , the lamp body 4 cannot rotate but can only move along the axial direction.

[0049] To elaborate, before the shell 2 and the lamp holder 1 are fastened together (i.e., before the extension portion 901 passes through the through hole), the moving contact 6 can retract into the through hole 201, and when the shell 2 and the lamp holder 1 are connected, under the rapid rebound force of the cylindrical spring 11, the moving contact 6 is quickly docked with the static contact 7 (i.e., the moving contact 6 is inserted into the static contact 7); in contrast, if the moving contact 6 and the static contact 7 are naturally docked when the shell 2 is pushed to the maximum stroke, the moving contact 6 is gradually inserted into the static contact 7, and if the staff pushes the shell 2 slowly at this time, it is easy to cause an arc and current sound between the moving contact 6 and the static contact 7, which may cause the lamp body 4 to flash, causing damage to the lamp body 4.

[0050] As another embodiment of the present invention, a method for adjusting the light output angle of the wide-angle spotlight is also proposed, comprising the following steps:

[0051] Step 1: fix the lamp holder 1 on the top of the wall or on the wall, so that the static contact 7 is connected to the power supply;

[0052] Step 2: Push the housing 2 into the lamp holder 1, and the housing 2 and the lamp holder 1 are fastened together by the elastic locking mechanism, and the electrical connection mechanism is connected to the static contact 7, so that the lamp body 4 is powered on;

[0053] Step three, operate the rotating adjustment mechanism, and drive the lamp body 4 to move toward the outside or inside of the reflector 3 by the rotating adjustment mechanism, and observe the light output angle until the light output angle meets the lighting requirements.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
