Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, and particularly relates to an intelligent dimmable LED lamp capable of improving the light source diffusion degree. Background Art

[0002] LED lamps have many advantages that cannot be compared with traditional light sources, such as energy saving and high efficiency, high luminous efficiency, low power consumption, long service life, pure light color, high stability, strong safety, environmental protection, etc. They are a kind of low-carbon, green and environmental protection lighting source.

[0003] However, the LED light sources inside the existing LED lamps are all fixedly installed, and the irradiation direction of the LED light sources cannot be adjusted. The light output effect of the lamps is single and cannot meet the use requirements of various occasions. At the same time, the existing LED lamps do not emit light evenly, which affects the use effect of the lamps. Summary of the Utility Model

[0004] In view of the above existing technical problems, the utility model provides an intelligent dimmable LED lamp capable of improving the light source diffusion degree.

[0005] The technical solution of the utility model is as follows: an intelligent dimmable LED lamp capable of improving the light source diffusion degree, comprising a lamp housing, a main lamp movably arranged at the bottom end of the lamp housing, and an auxiliary lamp assembly movably arranged on the lamp housing and located outside the main lamp; an installation cavity is arranged inside the lamp housing, and a lamp cover is movably clamped at the bottom end of the lamp housing and located outside the main lamp and the auxiliary lamp assembly;

[0006] The auxiliary lamp assembly includes a first adjusting disc slidably clamped inside the installation cavity, an adjusting sleeve sleeved outside the lamp housing and connected to the first adjusting disc, several auxiliary lamps evenly distributed inside the adjusting sleeve, and a first electric push rod arranged at the center position of the top inside the installation cavity and connected to the first adjusting disc.

[0007] Further, a second adjusting disc is slidably clamped inside the adjusting sleeve, a second electric push rod connected to the second adjusting disc is arranged at the top inside the adjusting sleeve, and fixing frames are arranged at positions corresponding to each auxiliary lamp inside the adjusting sleeve; each auxiliary lamp is rotatably clamped to the corresponding fixing frame through a connecting rotating shaft, and driving gears are sleeved on each connecting rotating shaft; racks meshed with each driving gear are arranged on the lower bottom surface of the second adjusting disc;

[0008] Explanation: The second electric push rod is used to push the second adjusting disc to move inside the adjusting sleeve. During the movement of the second adjusting disc, the driving gears are rotated by the racks, and finally the connecting rotating shafts drive the auxiliary lamps to rotate on the fixing frames, realizing the adjustment of the irradiation directions of the auxiliary lamps, which is beneficial to improving the light source diffusion degree of the utility model.

[0009] Furthermore, several support columns are evenly distributed inside the installation cavity and penetrate through the first adjustment disk respectively. The top ends of the support columns are movably hinged with movable plates. One end of each movable plate close to the first electric push rod is slidably clamped with a first pull rod fixedly connected to the first adjustment disk. One end of each movable plate far from the first electric push rod is slidably clamped with a second pull rod that penetrates through the first adjustment disk and the lamp housing and is connected to the main lamp.

[0010] Explanation: When the first push rod pulls the first adjustment disk to move upward inside the installation cavity, the adjustment sleeve drives each auxiliary lamp to move upward along the outer wall of the lamp housing. At this time, the first pull rod pushes the movable plate to rotate at the top end of the support column, and the second pull rod pushes the main lamp to move downward, so that the light source of the present invention can be diffused around.

[0011] Furthermore, heat dissipation fins are arranged on the outer side wall of the lamp housing.

[0012] Explanation: By arranging the heat dissipation fins, it is beneficial to quickly discharge the heat generated when the main lamp and the auxiliary lamps work, which is beneficial to improving the service life of the present invention.

[0013] Furthermore, a fixing seat is arranged at the top end of the lamp housing.

[0014] Explanation: By arranging the fixing seat, it is beneficial to improve the installation stability of the present invention.

[0015] The working principle of the present invention is as follows:

[0016] During use, when the first push rod is used to pull the first adjustment disk to move upward inside the installation cavity, at this time, the adjustment sleeve drives each auxiliary lamp to move upward along the outer wall of the lamp housing. The first pull rod pushes the movable plate to rotate at the top end of the support column, and the second pull rod pushes the main lamp to move downward. At the same time, the second electric push rod is used to push the second adjustment disk to move inside the adjustment sleeve. During the movement of the second adjustment disk, the rack pushes the driving gear to rotate, and finally the connecting rotating shaft drives the auxiliary lamp to rotate on the fixing frame, so that each auxiliary lamp irradiates the light source to the outside of the lamp housing.

[0017] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects:

[0018] First, the structure of the present invention is reasonably designed. By arranging auxiliary lamps outside the main lamp and using the first electric push rod to pull each auxiliary lamp to move upward along the outer wall of the lamp housing, a certain height difference is formed between the main lamp and the auxiliary lamps, which is beneficial to improving the light source diffusion range of the present invention.

[0019] Second, in the present utility model, each auxiliary lamp is rotationally clamped inside the adjusting sleeve. The second electric push rod is used to push the second adjusting disk to move inside the adjusting sleeve, and the meshing action of the rack and the driving gear is utilized to realize the adjustment of the irradiation direction of each auxiliary lamp, further expanding the light source diffusion degree and the light emission uniformity of the present utility model;

[0020] Third, by arranging heat dissipation fins on the outer part of the lamp housing in the present utility model, it is beneficial to improve the heat dissipation effect during the operation of the present utility model, thereby increasing the service life of the present utility model.
