Description

Technical Field

[0001] This utility model relates to the technical field of lighting devices, and in particular to a lighting device with adjustable illumination range. Background Technology

[0002] In the lighting field, traditional lighting equipment has long held a dominant position. However, most traditional lighting equipment uses thermal radiation or gas discharge principles to emit light, which has many drawbacks. For example, incandescent lamps have extremely low luminous efficiency, with most of the electrical energy being converted into heat energy, resulting in a large waste of energy. LEDs, on the other hand, are solid-state semiconductor devices that directly convert electrical energy into light energy through the recombination of electrons and holes. Their energy conversion efficiency is far higher than that of traditional lighting equipment, resulting in significant energy savings. Existing lighting devices have a fixed illumination range, typically radiating outwards from the center of the lamp or forming a beam, making it inconvenient to adjust the size of the illumination range as needed. Therefore, an adjustable illumination range lighting device was designed to address the aforementioned problems. Summary of the Invention

[0003] The purpose of this invention is to provide a lighting device with adjustable illumination range to solve the problems mentioned in the background art.

[0004] The technical solution adopted in this utility model is: An adjustable lighting device includes: a lighting lamp disposed at the bottom of a mounting base; an adjustment assembly disposed between the mounting base and the lighting lamp, the adjustment assembly comprising: two ends of a cylinder respectively fixedly connected to the mounting base and the lighting lamp; a motor fixedly disposed on the inner side wall of the bottom of the cylinder; a threaded rod fixedly disposed on the output shaft of the motor; a plate penetrated by the threaded rod and threadedly connected to the threaded rod; one end of a connecting rod inserted into the interior of the cylinder and rotatably connected to the plate; a rotating rod rotatably disposed at the bottom end of the connecting rod, and one end of the rotating rod rotatably connected to the outer side wall of the lighting lamp; and an elastic cloth fixedly disposed at the included angle of the rotating rod.

[0005] In some embodiments, the elastic fabric is a black, light-blocking material.

[0006] In some embodiments, one end of the connecting rod is the same width as the inner side of the groove on the cylinder.

[0007] In some embodiments, five sets of connecting rods and rotating rods are provided.

[0016] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] Given that current technologies generally use lighting fixtures that radiate light outwards from the center or are in the shape of a beam, the size of the illumination range cannot be adjusted as needed, which is inconvenient.

[0018] As shown in the attached figures, this embodiment of the invention provides a lighting device with adjustable illumination range. The device includes: a lighting lamp 12 disposed at the bottom of a mounting base 11; an adjustment assembly 2 disposed between the mounting base 11 and the lighting lamp 12, the adjustment assembly 2 comprising: a cylinder 21 with both ends fixedly connected to the mounting base 11 and the lighting lamp 12 respectively; a motor 22 fixedly disposed on the inner side wall of the bottom of the cylinder 21; a threaded rod 23 fixedly disposed on the output shaft of the motor 22; a plate 24 penetrated by the threaded rod 23 and threadedly connected to the threaded rod 23; a connecting rod 25 with one end inserted into the interior of the cylinder 21 and rotatably connected to the plate 24; a rotating rod 26 rotatably disposed at the bottom end of the connecting rod 25, and one end of the rotating rod 26 rotatably connected to the outer side wall of the lighting lamp 12; and an elastic cloth 27 fixedly disposed at the included angle of the rotating rod 26.

[0019] Specifically, the mounting base 11 needs to be fixed on the bracket, and the lighting lamp 12 and the motor 22 need to be connected to the external power supply. The specific connection method is the same as the existing equipment connection method.

[0020] When the lighting range needs to be adjusted during use, the motor 22 can be controlled to rotate the threaded rod 23 and move the plate 24 up and down while rotating. As the plate 24 moves up and down, it will drive the connecting rod 25 to rotate. The connecting rod 25 pulls the rotating rod 26 to rotate. When the rotating rod 26 rotates, it can pull the elastic cloth 27 to unfold, thereby adjusting the lighting range.

[0021] In some embodiments, the elastic fabric 27 is a black light-blocking material.

[0022] The design of the light-blocking material can better isolate the light source, making the light source more concentrated.

[0023] In some embodiments, one end of the connecting rod 25 is the same width as the inner side of the groove on the cylinder 21.

[0024] The consistent width design makes the plate 24 more stable when moving up and down.

[0025] In some embodiments, five sets of connecting rods 25 and rotating rods 26 are provided.

[0026] It is equipped with five sets to better support the elastic fabric 27. In some embodiments, the mounting base 11 is provided with a mounting component 3, the mounting component 3 including: a protrusion 31 with one end penetrating through the mounting base 11; a through groove 32 formed on the outer side wall of the protrusion 31; and a pin 33 with one end inserted into the interior of the through groove 32.

[0027] When the mounting base 11 needs to be installed and fixed, first fix the protrusion 31 on the plane of the bracket, then fit the mounting base 11 against the plane of the bracket, while the protrusion 31 passes through the mounting base 11, and then the pin 33 passes through the through groove 32 on the protrusion 31 to complete the installation of the mounting base 11.

[0028] In some embodiments, the mounting assembly 3 further includes a cone 34 fixedly disposed at the bottom end of the protrusion 31.

[0029] The design of the cone-shaped 34-point tip makes it relatively easier to pass through the mounting base.

[0030] In some embodiments, the mounting assembly 3 further includes a rubber ring 35 fixedly sleeved on the outer side wall of one end of the pin 33.

[0031] The design of the rubber ring 35 makes it less likely for the pin 33 to fall off after passing through the through groove 32.

[0032] In some embodiments, the mounting components 3 are provided in five groups, all of which are mounted on the mounting base 11.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
