[0002] The existing lighting system with adjustable illumination angle includes a base and a lamp rotatably arranged between side walls on both sides of the base. When in use, after being fixed at a specific position by the base, to adjust the illumination direction, it is only necessary to rotate the lamp. Since this lighting system with adjustable illumination angle needs to be fixed at a specific position, its flexibility of use is greatly limited, and it is very inconvenient when the installation position needs to be changed. Summary of the invention

[0003] The purpose of the utility model is to provide a lighting system with adjustable illumination angle, which can overcome one or more of the above-mentioned disadvantages and is flexible to use and easy to install.

[0004] The utility model is implemented as follows, including a bracket, and a long strip light rotatably arranged on the bracket. The special feature of the utility model is that an inlay groove is arranged on the top of the bracket, and a conductive cable is inlaid through the inlay groove. Positioning side plates are arranged at both ends of the bracket facing away from the inlay groove. The long strip light is rotatably arranged between the two positioning side plates. A needle thorn is arranged at the bottom of at least one end of the inlay groove. The position of the needle thorn matches the position of the wire of the conductive cable embedded in the inlay groove. The conductive wire is connected between the long strip light and the needle thorn. Positioning structures for positioning the conductive cable in the inlay groove are arranged at both ends of the inlay groove. The positioning structure above the needle thorn presses the conductive cable toward the needle thorn, so that the needle thorn penetrates into the conductive cable and is in close contact with the wire.

[0005] When in use, the wire cables are arranged according to the design, and then the lighting system with adjustable illumination angle of the utility model is fixed on the conductive cable through the positioning structure, and the needles on the lighting system with adjustable illumination angle are inserted into the conductive cable to closely contact the wires to complete the power connection and fixation. Due to the use of cable quick connection technology, the lighting system with adjustable illumination angle of the utility model can be conveniently and quickly disassembled and assembled to conveniently adjust the layout position of the lighting system with adjustable illumination angle of the utility model, and the mobility of the conductive cable can be utilized to conveniently move and set the lighting system with adjustable illumination angle of the utility model as needed. After the position of the lighting system with adjustable illumination angle of the utility model is set, the illumination direction of the light can be adjusted by rotating the long strip light.

[0006] By adopting the technology of this patent application, the flat shape of the wire cable (because the wires of the conductive cable are arranged horizontally side by side, the wire cable is flat) is utilized in combination with the inlay groove to ensure the stability of the bracket and stabilize the lighting direction.

[0007] Preferably, the bracket includes an intermediate frame body with an inlay groove on the top, a positioning frame body with inlay grooves on the tops of both ends of the intermediate frame body, the positioning side plates are located on the positioning frame body, the needle piercing is arranged on the inlay groove of the positioning frame body, the positioning structure is arranged on the positioning frame body, a positioning inlay groove is arranged at the end of the intermediate frame body, a matching inlay block is arranged at the facing position of the positioning inlay groove of the positioning frame body, and the inlay block is inlaid into the positioning inlay groove to position the positioning frame body at both ends of the intermediate frame body.

[0010] Preferably, the bottom of the cylindrical recess is provided with concave-convex patterns distributed along the circumference, and a matching positioning marble is provided on the cylindrical rotating head of the long strip light. When the long strip light is rotated, the positioning is achieved by the positioning marble being stuck on the concave-convex patterns, which neither affects the rotation of the long strip light to adjust the illumination angle.

DETAILED DESCRIPTION

[0018] The lighting system with adjustable illumination angle of the utility model is now described in further detail with reference to the accompanying drawings and embodiments:

[0019] The lighting system with adjustable illumination angle of the utility model is realized as follows, including a bracket 1, and a long strip light 2 rotatably set on the bracket 1. The special feature is that a mounting groove 3 is set on the top of the bracket 1, and a conductive cable 4 is embedded in the mounting groove 3. Positioning side plates 5 are set at both ends of the bracket 1 facing away from the mounting groove 3. The long strip light 2 is rotatably set between the two positioning side plates 5. A needle thorn 6 is set at the bottom of at least one end of the mounting groove 3. The position of the needle thorn 6 matches the position of the wire 401 of the conductive cable 4 embedded in the mounting groove 3. The conductive wire 7 is connected between the long strip light 2 and the needle thorn 6. Positioning structures 8 for positioning the conductive cable 4 in the mounting groove 3 are set at both ends of the mounting groove 3. The positioning structure 8 on the needle thorn 6 presses the conductive cable 4 toward the needle thorn 6, so that the needle thorn 6 penetrates into the conductive cable 4 and is in close contact with the wire 401.

[0020] The positioning structure 8 includes a threaded hole 801 disposed on the mounting groove 3 and reaching the bottom of the mounting groove 3, and a screw 802 screwed on the threaded hole 801. Figure 2 As shown, the top surface of the screw rod 802 is provided with a structure 803 that can be rotated by a screwdriver, or as shown in FIG. Figure 4 As shown, a knob 804 is provided on the screw 802 for convenient manual rotation. When in use, the screw 802 is rotated by a screwdriver; or the knob 804 is rotated manually, and the screw 802 presses the conductive cable 4 toward the needle 6, so that the needle 6 penetrates into the conductive cable 4 and is in close contact with the wire 401, and at the same time, the conductive cable 4 is fixed at both ends of the embedding groove 3.

[0021] An optical sheet 203 is provided on the light emitting surface of the long strip lamp holder 202, which can realize single deflection, double deflection, or change the light shape.

[0022] Due to the structure of the long strip lamp holder 202 and the position where it is installed, the light emitted by the long strip lamp holder 202 is irradiated forward, but not to the sides. Even if the long strip lamp holder 202 is rotated to expand the fan-shaped range that can be irradiated, it still cannot meet the irradiation requirements, such as irradiating the ceiling.

[0023] A single-biased optical sheet 203 is provided. Through the light deflection effect of the optical sheet 203, the fan-shaped range illuminated by the long strip lamp head 202 is expanded. With the rotation of the long strip lamp head 202, the fan-shaped range of the light irradiated by the long strip lamp head 202 is greatly increased, and can even illuminate the ceiling.

[0024] The double polarizing optical sheet 203 is used to expand the fan-shaped range of the light emitted by the long strip lamp holder 202 to both sides.

[0025] Due to the structure of the long strip lamp holder 202, its light source is often composed of multiple lamp beads arranged side by side, and the light emitted by the lamp beads is often a circular scattering range, resulting in discontinuous and uneven light. After using the optical sheet 203 that changes the light shape, the circular scattering range can be changed into a square scattering range, making the light emitted by the long strip lamp holder 202 continuous and uniform.

[0026] Preferably, the bracket 1 includes an intermediate frame 101 with an inlay groove 3 on the top, and a positioning frame 102 with inlay grooves 3 on the tops of both ends of the intermediate frame 101. The positioning side plates 5 are located on the positioning frame 102 and form a whole with the positioning frame 102. The needle puncture 6 is arranged on the inlay groove 3 of the positioning frame 102. The positioning structure 8 is arranged on the positioning frame 102. A positioning inlay groove 9 is arranged at the end of the intermediate frame 101. A matching inlay block 10 is arranged on the positioning frame 102 facing the positioning inlay groove 9. The inlay block 10 is inlaid into the positioning inlay groove 9 so that the positioning frame 102 is positioned at both ends of the intermediate frame 101.

[0027] Preferably, a cylindrical recess 11 is provided on the positioning side plate 5 facing the long strip light 2, and a cylindrical rotating head 12 is provided on the long strip light 2 corresponding to the cylindrical recess 11. The cylindrical rotating head 12 is rotatably connected in the cylindrical recess 11 through a screw 19 located on the rotation axis. In this way, the long strip light 2 can smoothly rotate along the cylindrical recess 11 to adjust the illumination angle.

[0028] Preferably, the bottom of the cylindrical recess 11 is provided with concave-convex patterns 13 distributed along the circumference, and a matching positioning marble 14 is provided on the cylindrical rotating head 12 of the long strip light 2. When the long strip light 2 is rotated, the positioning is achieved by the positioning marble 14 being stuck on the concave-convex pattern 13, which does not affect the rotation of the long strip light 2 to adjust the illumination angle. At the same time, after the angle is completed, the positioning can be achieved by the positioning marble 14 being stuck on the concave-convex pattern 13.

[0029] Preferably, the front end of the cylindrical rotating head 12 is an arc-shaped wall 15, and baffles 16 are provided on the inner sides of both ends of the arc-shaped wall 15. A stopper 17 is provided at the bottom of the cylindrical recess 11 at the rotation trajectory of the baffle 16 corresponding to the arc-shaped wall 15, so that the baffle 16 of the arc-shaped wall 15 at the front end of the cylindrical rotating head 12 is blocked by the stopper 17 to stop the cylindrical rotating head 12. At the same time, the conductive wire 7 connected to the acupuncture 6 is freely arranged in the space above the arc-shaped wall to prevent the conductive wire 7 from being blocked by obstacles and damaged when it rotates and moves with the cylindrical rotating head 12.

[0030] Preferably, the long strip light 2 includes a long strip light body 201 with a point light source and a long strip light head 202, the long strip light head 202 is fixedly connected together through an inlay hole and an inlay head structure 20, the cylindrical rotating head 12 and the positioning marble 14 are arranged on the long strip light head 202, the long strip light head 202 is provided with a through hole 18, and the conductive wire 7 passes through the through hole 18 and is connected to the point light source of the long strip light body 201. The structure of the long strip light body 201 and the long strip light head 202 is convenient for manufacturing and assembling of the long strip light 2.

[0031] When in use, the conductor cable 4 is arranged according to the design, and then the lighting system with adjustable illumination angle of the utility model is fixed on the conductive cable 4 through the positioning structure 8, and the needle 6 on the lighting system with adjustable illumination angle is inserted into the conductive cable 4 and in close contact with the conductor 401.
