Description

Technical Field

[0001] The utility model relates to the technical field of LED floodlights, and more specifically to an angle adjustment mechanism for LED floodlights. Background Art

[0002] With the continuous progress and development of intelligent lighting technology, the requirements for the accuracy of lighting control are being raised to a new level. The intelligent system not only needs to realize the basic switch control function of the lamp, but also must be able to accurately adjust a series of details such as the projection direction, angle and brightness of the light to meet the diverse lighting needs in different scenarios. In this technical background, the role played by the angle adjustment device of the LED floodlight is particularly important and indispensable.

[0003] However, in actual application, the angle adjustment device still has many shortcomings. For example, the angle adjustment speed of the floodlight is relatively slow, and it cannot respond to control instructions quickly; the accuracy of the angle adjustment is also relatively low, and it is difficult to achieve precise control of the lighting direction of the floodlight, which will undoubtedly greatly affect the lighting effect and user experience. At the same time, most of the existing devices only adjust the angle of a single LED floodlight, but in many actual lighting occasions, such as large indoor exhibitions, outdoor architectural lighting, etc., the light intensity of a single lamp is often difficult to meet the overall lighting needs. Therefore, it is particularly urgent and important to design an angle adjustment mechanism that is both efficient and accurate and can be applied to multiple LED floodlights. Utility Model Content

[0004] In order to overcome the deficiencies in the above-mentioned prior art, the utility model provides an angle adjustment mechanism for an LED floodlight. The mechanism can flexibly adjust the projection angle of the LED floodlight according to different scenes, such as indoor lighting layout, outdoor landscape lighting, etc., thereby improving the applicability of the device and enabling the mechanism to play a role in a variety of lighting demand scenes.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] An angle adjustment mechanism for an LED floodlight comprises a supporting assembly, an adjusting assembly and a floodlight assembly, wherein the supporting assembly comprises a supporting base, a mounting rod and a limiting frame, wherein the mounting rod is arranged on the supporting base, the limiting frames are symmetrically arranged on both sides of the supporting base, and slide grooves are arranged in the limiting frames, the adjusting assembly comprises an installing box, the bottom of the installing box is connected to the mounting rod, and the two sides of the installing box are movably connected to the limiting frames, and the floodlight assembly is arranged in the installing box.

[0007] The installation rod adopts a semi-cylindrical structure, a worm gear is arranged on the outer surface of the installation rod, and the bottom of the installation box is connected to the worm gear.

A driving rod is provided in the limit seat, and a worm is provided outside the driving rod. The worm is meshed with the worm gear, and limit rods are symmetrically provided on both sides of the installation box, and the limit rods are slidably arranged in the limit frame.

[0009] The limiting frame adopts a semicircular frame body.

[0010] A mounting frame is arranged at one side of the mounting box, a driving motor is arranged on the mounting frame, and an output end of the driving motor is fixedly connected to the driving rod.

[0011] A plurality of installation slots are arranged on the upper part of the installation box, and the light projection components are arranged in the installation slots.

[0012] The projection light assembly includes a plurality of power modules and a plurality of LED projection lights. The power modules are correspondingly arranged in each installation slot. The LED projection lights are fixedly arranged above the power modules. Adjacent LED projection lights are connected via a first connecting frame.

[0013] A second connecting frame is arranged on the outermost LED floodlight.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The limit seat provides a rotation support point and limit space for the drive rod, so that the drive rod will not deviate or shake during the rotation process, thereby ensuring the stability of the connection between the drive rod and the worm, and ensuring that the subsequent meshing transmission with the worm wheel can be carried out accurately; the mounting frame can provide a stable installation position for the drive motor to prevent the drive motor from being displaced due to vibration or external force during operation, which helps to ensure that the power output by the drive motor can be stably transmitted to the drive rod, thereby ensuring the normal operation of the entire angle adjustment mechanism; under the combined action of the worm wheel and the worm, it can ensure that the power generated by the drive motor is effectively transmitted to the drive rod. During the angle adjustment process, stable power transmission realizes precise angle adjustment operation; it can also achieve a certain deceleration and force increase effect, which is effective It helps to achieve stable angle adjustment under limited driving motor power; the design of a single power module to control the LED floodlight ensures the independent operation of each LED floodlight, and the number of working LED floodlights can be controlled during use to meet various lighting needs; the design of the limit frame plays a key limiting role when the installation box is adjusted for angle. The cooperation of the limit rod and the limit frame can limit the rotation range of the installation box to prevent the installation box from excessive rotation or shaking during the adjustment process, thereby ensuring the stability of the floodlight assembly during the adjustment process and the accuracy of the angle adjustment; the setting of the first connecting frame ensures the stability between the LED floodlights and prevents a single floodlight from falling. The setting of the second connecting frame facilitates the operator to grab when picking up and placing the LED floodlight. This mechanism flexibly adjusts the projection angle of the LED floodlight and the number of floodlights turned on according to different usage scenarios, which improves the scope of application of the equipment and enables the mechanism to play a role in various lighting demand scenarios.
