Description

Technical Field

[0001] The present invention relates to the field of track lights, and particularly to a track light with adjustable illumination angle. Background Art

[0002] A track light is a lamp installed on a similar track and can adjust the irradiation angle arbitrarily. Generally, it is used as a spot light. The track light must be installed on a matching track. The track contains voltage input, and there are conductive metal strips on both sides inside the track. The joint of the track light has a rotatable conductive copper sheet. When installing, the conductive copper sheet on the track light contacts the conductive metal strip inside the track, and the track light can be powered on and lit.

[0003] Currently, when the spot lights on the track need to change positions, it is necessary to manually remove the track lights, and then install them on the track again after determining the positions. Moreover, for the spot lights used in the track lights, their irradiation angles (horizontal angle or vertical angle) need to be manually adjusted. Generally, the height of the track spot lights from the ground is about 2.5 meters. Manual adjustment requires the use of a step ladder, which is inconvenient and there is a certain danger. In addition, generally, there are multiple spot lights installed on the track, and it is even more inconvenient to quickly adjust the angles and positions of each spot light.

[0049] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0050] Example 1, as Figures 1-3As shown in the figure, an adjustable illumination angle track light includes a track body 8, a junction box 2 and a spotlight 3. The junction box 2 is installed on one side of the track body 8, and the spotlight 3 is located below the track body 8. A support frame 9 is inserted into the track body 8 through a slot. A conductive copper bar 10 for conducting electricity to the lamp is fixed along the length direction of the support frame 9. And a limiting slot 11 is arranged at the bottom of the support frame 9 inside the track body 8. A connection box 4 is arranged at the bottom of the track body 8. An electric pan-tilt 5 for adjusting the horizontal illumination direction and the vertical illumination direction of the spotlight 3 is installed between the connection box 4 and the spotlight 3 (when the electric pan-tilt 5 controls the horizontal illumination direction of the spotlight 3, it mainly depends on the motor in the horizontal rotation direction of its internal output shaft. When controlling the vertical illumination direction of the spotlight 3, it mainly depends on the motor in the vertical rotation direction of its internal output shaft).

[0051] At the top of the connection box 4, a moving limiting component 15 for moving inside the limiting slot 11, a conductive component 14 for conducting electricity with the conductive copper bar 10, and a control component 13 for adjusting the steering of the electric pan-tilt 5 are installed.

[0052] The outside of the track body 8 is connected with a housing 1 through a connecting piece. At the top inside the housing 1, a triggering component for triggering the control component 13 to work is installed.

[0053] Further, the connecting piece includes two connecting plates 16 and two lower guide rails 17. The two connecting plates 16 are respectively fixed on both sides of the bottom inside the housing 1, and the two lower guide rails 17 are respectively fixed on both sides of the bottom outside the track body 8. One side of the connecting plate 16 is inserted into the inside of the lower guide rail 17.

[0054] Further, the moving limiting component 15 includes a limiting box 151 and two L-shaped brackets 153. The limiting box 151 is fixed at the top of the connection box 4. The two L-shaped brackets 153 are symmetrically arranged on both sides inside the limiting box 151. The top of the L-shaped bracket 153 extends above the limiting box 151, and a pulley 154 is rotatably connected to the top of the L-shaped bracket 153 through a rotating shaft. An activity slot 152 for the movement of the L-shaped bracket 153 is opened at the top of the limiting box 151.

[0055] A partition plate 156 is vertically fixed in the middle of the inside of the limiting box 151. Guide posts 157 are fixed on both sides of the partition plate 156. The guide posts 157 penetrate through the L-shaped bracket 153, and a second spring 158 is sleeved outside the guide posts 157 between the L-shaped bracket 153 and the partition plate 156. Pressing pieces 155 for pushing the L-shaped bracket 153 to move are arranged on both sides of the outside of the limiting box 151.

[0056] The pressing piece 155 includes an arc-shaped plate and a connecting column. One end of the connecting column is connected with the arc-shaped plate, and the other end of the connecting column extends into the limiting box 151 and is connected with the L-shaped bracket 153.

[0057] Furthermore, the rotating shaft at the connection between the L-shaped bracket 153 and the pulley 154 is a damping rotating shaft, and the thickness of the pulley 154 is less than the height inside the limiting groove 11.

[0058] Furthermore, the conductive assembly 14 includes a conductive box 141 fixed to the top of the connection box 4. A hollow cavity 148 and two side cavities 142 are provided inside the conductive box 141;

[0059] A conductive rod 143 is arranged inside the side cavity 142. One end of the conductive rod 143 extends to the outside of the conductive box 141, and the other end of the conductive rod 143 extends to the inside of the hollow cavity 148;

[0060] The part of the conductive rod 143 extending to the outside of the conductive box 141 is in a hemispherical structure;

[0061] A conducting wire 147 is connected to the part of the conductive rod 143 extending to the inside of the hollow cavity 148;

[0062] A limiting ring 146 is fixed outside the conductive rod 143 inside the side cavity 142. A limiting plate 144 is fixed outside the conductive rod 143 inside the side cavity 142. A first spring 145 is sleeved on one side of the limiting plate 144 outside the limiting ring 146;

[0063] An isolating plate 149 is fixed at the middle inside the hollow cavity 148.

[0064] Furthermore, the conductive box 141, the limiting ring 146, the limiting plate 144, and the isolating plate 149 are all made of insulating materials. The outside of the first spring 145 is coated with insulating paint to further improve the safety during the conduction process of the conductive rod 143 and avoid electric leakage.

[0065] The working principle of the above technical solution is as follows:

[0066] First, insert the connecting plate 16 into the inside of the lower guide rail 17 to form an integral body of the housing 1 and the track body 8. Then install the housing 1. The shape of the housing 1 is the same as the external structure of the existing track light in the embedded installation type, so the installation method is also the same. After the housing 1 is installed, energize the conductive copper bars 10 in the track body 8 through the junction box 2 (the junction box is a common component of the existing track light. The simplest structure is two terminals. One end of each of the two terminals is connected to the external power supply line, and the other end of each of the two terminals is electrically connected to the conductive copper bars on both sides inside the track. This is a conventional technology and will not be elaborated in detail);

[0067] Press the two pressing members in the movable limit assembly 15 inward to move the two L-shaped brackets 153 and the two pulleys 154 towards each other. Then, push the two pulleys 154 into the interior of the track body 8. After the pulleys 154 are flush with the limit slots 11, release the pressing members. Under the action of the second spring 158 and the guide post 157, the two L-shaped brackets 153 and the two pulleys 154 will reset, thereby enabling the pulleys 154 to enter the limit slots 11, and ensuring that the spotlight 3 can be stably installed at the bottom of the track body 8;

[0068] When the pulley 154 enters the limit slot 11, the conductive rod 143 will also contact the conductive copper bar 10 (since the part of the conductive rod 143 in contact with the conductive copper bar 10 is in a hemispherical structure, and the two sides of the support frame 9 are in an arc transition, therefore, when the conductive rod 143 enters between the conductive copper bars 10, it will not be blocked by the support frame 9);

[0069] Under the action of the first spring 145, the limit plate 144 can be continuously extruded towards the direction of the conductive copper bar 10, thereby ensuring that the conductive rod 143 can be in real-time contact with the conductive copper bar 10 and ensuring the stability during the conduction process;

[0070] The current of the conductive copper bar 10 will be transmitted to the electric pan-tilt 5 and the spotlight 3.

[0071] Embodiment 2, refer to Figures 1-8 As shown, the control assembly 13 includes a support tube 131 fixed to the top of the connection box 4. A cover plate 132 is fixed to the top of the support tube 131. Three parallel grooves 133 are opened on the top of the cover plate 132. An electromagnet 136, a B2 magnet 135, and an A2 magnet 134 are sequentially arranged inside the three parallel grooves 133 from left to right. Limit posts 137 are fixed to the bottoms of the electromagnet 136, the B2 magnet 135, and the A2 magnet 134. The bottoms of the limit posts 137 penetrate through the cover plate 132 and extend into the interior of the support tube 131, and a pressing plate 138 is fixed to the outside of the limit posts 137 near the bottom thereof. Among them, the interior of the limit post 137 at the bottom of the electromagnet 136 is hollow to facilitate the wire to pass through and supply power to the electromagnet 136;

[0072] Light touch switches 139 are installed at the bottom of the cover plate 132 below the electromagnet 136, the B2 magnet 135, and the A2 magnet 134 (the light touch switch is also called a push-button switch. When in use, when the operating force condition is met and pressure is applied in the operating direction of the switch, the switch function is closed and connected. When the pressure is withdrawn, the switch is disconnected. Its internal structure realizes on-off by the force change of the metal elastic sheet. This is a conventional technology). The pressing plate 138 is located below the light touch switches 139.

[0073] Further, the distance from the top of the electromagnet 136, the B2 magnet block 135, and the A2 magnet block 134 to the top of the cover plate 132 is greater than the distance from the top of the pressing plate 138 to the touch end of the touch switch 139.

[0074] Further, the triggering assembly includes a forward and reverse motor 6 and two upper guide rails 7. The two upper guide rails 7 are symmetrically fixed on both sides inside the housing 1. A movable plate 22 is slidably connected between the two upper guide rails 7. The movable plate 22 is located above the track body 8. The forward and reverse motor 6 is installed inside the housing 1, and a main synchronous pulley 19 is fixed on the transmission shaft of the forward and reverse motor 6. The main synchronous pulley 19 is located above the movable plate 22. A slave synchronous pulley is installed at one end of the housing 1 away from the main synchronous pulley 19 through a rotating shaft. A synchronous belt 20 is installed between the main synchronous pulley 19 and the slave synchronous pulley;

[0075] A fixing plate 21 is fixed on the top of the movable plate 22. The fixing plate 21 is fixedly connected to the synchronous belt 20. The bottom of the movable plate 22 is step - fixed with a magnet 25, a B1 magnet block 26, and an A1 magnet block 27. Three guide grooves 12 are opened on the top of the track body 8. The magnet 25, the B1 magnet block 26, and the A1 magnet block 27 can move in the three guide grooves 12 respectively.

[0076] Further, an L - shaped connecting rod 28 is fixed on one side of each of the magnet 25, the B1 magnet block 26, and the A1 magnet block 27. The bottom ends of the three connecting rods 28 are fixed with a reflector 29 on the top of the connecting plate 16. The reflecting colors of the three reflectors 29 are different. A plurality of rectangular holes are opened inside the connecting plate 16. A transparent baffle 18 is installed inside the rectangular holes. A marking plate 23 parallel to the electromagnet 136, the B2 magnet block 135, and the A2 magnet block 134 is fixed on one side of the connection box 4. The upper guide rail 7 is fixed with a limit bolt 24 near its two ends. By irradiating the reflector 29 and the marking plate 23, when the reflector 29 coincides with the marking plate 23, the corresponding states of the current magnet 25, the B1 magnet block 26, and the A1 magnet block 27 and the electromagnet 136, the B2 magnet block 135, and the A2 magnet block 134 can be judged.

[0077] The working principle of the above - mentioned technical solution is as follows:

[0078] (In the present invention, there are two groups of independent power supplies and controls. The first group is the power supply for the forward and reverse motor 6, and the second group is the power supply for the electric pan - tilt 5, the electromagnet 136, and the spotlight 3. In the actual scenario, for the control switches or control panels for the forward and reverse motor 6 and the spotlight 3, they can be the same as household switches and be set on the wall where people can easily touch them. Specific power supply access and control can all adopt conventional technologies).

[0079] During use, the positive and negative motor 6 drives the synchronous pulley 19 to rotate, causing the synchronous belt 20 to drive the fixed plate 21 and the movable plate 22 to move as a whole along the upper guide rail 7. During the movement of the movable plate 22, the magnetic block 25, B1 magnetic block 26, and A1 magnetic block 27 at its bottom will move along the three grooves 133 on the top of the track body 8;

[0080] At this time, keep the whole device powered on. When the A1 magnetic block 27 moves above the A2 magnetic block 134, turn off the positive and negative motor 6. The A1 magnetic block 27 will attract the A2 magnetic block 134 upward, thereby driving the A2 magnetic block 134, the limit post 137 and the pressing plate 138 connected to it to move upward, and then pressing the touch switch 139 corresponding to the lower part of the A2 magnetic block 134. When the touch switch 139 under the A2 magnetic block 134 is turned on, the motor in the horizontal rotation direction of the output shaft inside the electric pan-tilt 5 will work, thereby adjusting the irradiation angle of the spotlight 3 in the horizontal direction;

[0081] When the irradiation angle of the spotlight 3 in the horizontal direction is about to be adjusted, turn on the positive and negative motor 6 again, so that the A1 magnetic block 27 moves away from above the A2 magnetic block 134 and no longer attracts the A2 magnetic block 134. Since there is no upward attraction force on the A2 magnetic block 134, the A2 magnetic block 134 is reset under the influence of gravity, causing the pressing plate 138 below it to separate from the touch switch 139 below it, thereby stopping the motor in the horizontal rotation direction of the output shaft inside the electric pan-tilt 5 to ensure that the horizontal irradiation angle of the spotlight 3 remains in the current state;

[0082] As the positive and negative motor 6 continues to work;

[0083] The B1 magnetic block 26 will move above the B2 magnetic block 135. At this time, turn off the positive and negative motor 6. The B1 magnetic block 26 will attract the B2 magnetic block 135 upward, thereby driving the B2 magnetic block 135, the limit post 137 and the pressing plate 138 connected to it to move upward, and then pressing the touch switch 139 corresponding to the lower part of the B2 magnetic block 135. When the touch switch 139 under the B2 magnetic block 135 is turned on, the motor in the vertical rotation direction of the output shaft inside the electric pan-tilt 5 will work, thereby adjusting the irradiation angle of the spotlight 3 in the vertical direction;

[0084] When the irradiation angle of the spotlight 3 in the vertical direction is about to be adjusted, turn on the positive and negative motor 6 again, so that the B1 magnetic block 26 moves away from above the B2 magnetic block 135 and no longer attracts the B2 magnetic block 135. Since there is no upward attraction force on the B2 magnetic block 135, the B2 magnetic block 135 is reset under the influence of gravity, causing the pressing plate 138 below it to separate from the touch switch 139 below it, thereby stopping the motor in the vertical rotation direction of the output shaft inside the electric pan-tilt 5 to ensure that the vertical irradiation angle of the spotlight 3 remains in the current state;

[0085] So far, the adjustment operations for the horizontal and vertical irradiation directions of the spotlight 3 have been completed;

[0086] Similarly, as the forward and reverse motor 6 continues to operate;

[0087] The magnetic block 25 moves above the electromagnet 136. At this time, the magnetic block 25 will attract the non-energized electromagnet 136 upward, thereby driving the limiting column 137 and the pressing plate 138 connected to the electromagnet 136 to move upward, and then pressing the corresponding tactile switch 139 below the electromagnet 136. When the tactile switch 139 below the electromagnet 136 is turned on, the electromagnet 136 will be energized to further increase the magnetic attraction between the magnetic block 25 and the electromagnet 136;

[0088] As the forward and reverse motor 6 continues to operate, during the movement of the movable plate 22, it will also drive the connection box 4 to move, thereby changing the position of the spotlight 3 on the track body 8. After the position of the spotlight 3 is changed, turn off the power supply of the spotlight 3 to make the electromagnet 136 unable to continue operating. After the magnetic block 25 moves away from above the electromagnet 136, the power supply of the spotlight 3 can be turned on again;

[0089] So far, the operation of adjusting the position of the spotlight 3 on the track has ended, and at the same time, it is also prepared for adjusting the illumination angle or the position of the next spotlight;

[0090] The reason why the rotating shaft at the connection between the L-shaped bracket 153 and the pulley 154 uses a damping rotating shaft is to ensure that only when the electromagnet 136 and the magnetic block 25 are strongly adsorbed, during the movement of the movable plate 22 driving the magnetic block 25, can the connection box 4 be driven to move (if it is the attraction between the A1 magnetic block 27 and the A2 magnetic block 134, and the attraction between the B1 magnetic block 26 and the B2 magnetic block 135, when the movable plate 22 drives the A1 magnetic block 27 or the B1 magnetic block 26 to move, under the action of the damping rotating shaft, the connection box 4 cannot be driven to move);

[0091] In summary, this solution can quickly adjust the horizontal and vertical irradiation angles of the track spotlight, and at the same time quickly change the position of the spotlight on the track. The adjustment process is fast and convenient, without manual contact with the spotlight, which is safer.

[0092] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
