Technical Field
[0001] The utility model relates to the technical field of LED lamps, in particular to an LED lamp capable of changing the light projection angle. Background Art
[0002] The LED lamp is an electroluminescent semiconductor material chip, which is cured to the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver wire or gold wire. It is sealed with epoxy resin on all sides to protect the internal core wire, and finally the outer shell is installed.
[0003] Existing LED lighting lamps often have a fixed irradiation angle, which is not convenient to adjust according to needs. When multiple LED lamps need to be adjusted to the same angle, it is easy to cause the angle adjustment of the front and rear LED lamps to be inconsistent, increasing the difficulty of adjustment. For this reason, we propose an LED lamp that can change the projection angle. Utility Model Content
[0004] The main purpose of the utility model is to provide an LED lamp with a variable light projection angle, which can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] In order to facilitate the control of the threaded rod to rotate, as an LED lamp capable of changing the projection angle of the utility model, one end of the threaded rod is fixedly connected to a control handle, and the threaded rod is threadedly connected to the inside of the protective cover.
[0008] In order to make the slide more stable, as an LED lamp capable of changing the light projection angle of the utility model, the front side of the fixing seat is fixedly connected with a fixing plate by bolts, and the fixing plate is fixedly connected to the upper surface of the slide.
[0009] In order to protect the gears and spur gears, as an LED lamp capable of changing the light projection angle of the utility model, the fixing seat is fixedly installed on the inner top wall of the protective cover, and a sliding hole is opened on the outer surface of the protective cover.
[0010] In order to facilitate observation of the position of the control handle, as an LED lamp capable of changing the light projection angle of the utility model, a scale is fixedly connected to the outer surface of the protective cover, and a scale bar is arranged on the front of the scale.
[0011] In order to make the installation of the lamp more stable, as an LED lamp with a variable light projection angle of the utility model, the front and back sides of the protective cover are fixedly connected with mounting plates, and locking bolts are arranged inside the mounting plates.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] The LED lamp capable of changing the projection angle is provided by the matching arrangement among the lamp head, the fixing rod, the rotating shaft, the fixing seat, the gear, the spur gear, the slideway, the threaded rod, the control handle and the scale. When a staff member twists the control handle to rotate the threaded rod, the spur gear can be pushed to move inside the slideway, and when the gear is rotated, the fixing rod can be rotated, so that the angle of the lamp head can be adjusted to meet the illumination demand. Moreover, when the staff member adjusts the position of the control handle of the LED lamp on the scale according to the adjustment, when adjusting the next LED lamp, it only needs to twist the control handle to adjust the control handle to the same position as the control handle of the previous LED lamp, so that the angles of other LED lamps can be adjusted more conveniently, quickly and accurately, saving time and effort.
