[0001] The utility model relates to the technical field of ophthalmic lamps, in particular to an ophthalmic LED lamp. Background Art

[0002] With the continuous development of ophthalmic medical technology, the requirements for surgical light sources in ophthalmic surgery are also increasing.

[0003] The existing ophthalmic LED lamps are mostly adjusted by mechanical structures such as rotation or sliding. Although this adjustment method can meet the needs of normal ophthalmic surgery, whether it is the adjustment of the horizontal angle, pitch angle or horizontal position, it is often necessary to fix the adjusted position through an additional fixing device, which increases the complexity of the equipment and leads to low adjustment efficiency. For this reason, we propose an ophthalmic LED lamp. Utility Model Content

[0006] The top surface of the rotating block is provided with a friction assembly that can be raised and lowered, and the friction assembly is used to abut against the mounting plate, the first slide plate and the second slide plate.

[0011] Preferably, a knob is fixedly mounted on the upper end of the threaded rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The ophthalmic LED lamp drives the first slide plate and the LED lamp body to rotate as a whole by rotating the rotating block, thereby changing the horizontal angle position of the LED lamp body, and simultaneously controlling the movement of the first slide plate and the second slide plate to change the horizontal position of the LED lamp body. By only moving the second slide plate, the second slide plate changes the angle between the LED lamp body and the first slide plate through the connecting rod, thereby adjusting the pitch angle of the LED lamp body, thereby improving the flexibility of adjusting the ophthalmic LED lamp.

[0014] 2. For the ophthalmic LED lamp, after adjusting the LED lamp body to the specified position, the knob is turned to drive the threaded rod to rotate, thereby driving the moving plate to move downward, and the moving plate drives the first friction block to contact the mounting plate, so that the horizontal angle position between the rotating block and the mounting plate is fixed, thereby fixing the horizontal angle position of the LED lamp body, and at the same time, the second friction block moves to contact the first slide plate, so that the horizontal position of the first slide plate is fixed, and at this time the third friction block contacts the second slide plate, so that the horizontal position of the second slide plate is fixed, thereby fixing the pitch angle and horizontal position of the LED lamp body, thereby fixing the position of the LED lamp body as a whole, and its fixing method is relatively convenient, which improves the adjustment efficiency of the LED lamp in ophthalmic surgery.
