The design of the heat sink 37 can effectively dissipate the heat generated by the light source 32, ensure that the temperature of the lamp is maintained within a safe range during long-term use, and extend the life of the light source. The design of the light source bracket 321 ensures stable support of the light source 32, and avoids loosening or damage of the light source due to vibration or collision.

[0036] The working principle of this embodiment is as follows:

[0037] A process of using a rotatable and limited lamp, such as Figure 1 As shown, when the operator wants to change the illumination angle of the lamp, the sealing plate and the rubber ring are removed and the nut is unscrewed so that the lighting lamp body and the main bracket of the lamp can rotate relative to each other. The amplitude limiting structure can limit the rotation angle to prevent excessive rotation and damage to the lighting lamp body. After adjusting the lighting lamp body to a suitable angle, the nut is tightened to lock the lighting lamp body and the main bracket of the lamp, and then the sealing plate and the rubber ring are reinstalled in the original position of the main bracket of the lamp. Repeating the above operation can readjust the rotation angle of the lighting lamp body. It has high flexibility and the user can freely adjust the angle of the lighting lamp body according to actual needs, so as to better meet the lighting needs in different occasions and uses. Through simple disassembly and assembly steps, the user can readjust the angle of the lighting lamp body at any time without the need for professional tools or complicated operations. The amplitude limiting structure can effectively prevent the lighting lamp body from rotating too much, avoid damage caused by excessive twisting, and increase the service life of the product.
