Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a precision orientation lighting lamp. Background Technique

[0002] With the development of technology, the rise of numerically controlled machine tools has brought revolutionary changes to the machinery manufacturing industry. Numerically controlled machine tools not only have good processing flexibility, high precision, high production efficiency, but also can reduce the labor intensity of operators. However, because the processing of numerically controlled machine tools in the workshop runs for a long time, it will be affected by the light changes in the workshop. It is very inconvenient to use numerically controlled machine tools at night or in insufficient light. Most workshops are equipped with lighting devices. Installing lighting lamps in numerically controlled machine tools can provide sufficient lighting when the numerically controlled machine tools are working, which is convenient for observing the clamping and processing of workpieces, as well as the maintenance and cleaning of the machine tools.

[0003] In the prior art, such as a Chinese patent with the application number 202021735530.8, the authorized announcement number CN212617889U, and the invention name "an adjustable lighting lamp for large-precision numerically controlled machine tool processing", the above patent discloses an adjustable lighting lamp for large-precision numerically controlled machine tool processing, including a sliding component, a lamp body, a lamp base, a lamp support rod, and a light-shielding component. The lower side of the lamp body is connected to the lamp base through the lamp support rod. The bottom end of the lamp base is connected to the sliding component. The outside of the lamp body is equipped with a light-shielding component. The light-shielding component includes a sleeve, a vertical rod, a connecting rod, a first-level light guide plate, and a second-level light guide plate. The outer wall of the sleeve is evenly installed with vertical rods along the circumferential direction. There are 6 vertical rods. Connecting rods are connected between the vertical rods. A first-level light guide plate is rotatably installed on the connecting rod through a damping rotating shaft. The outer end of the first-level light guide plate is rotatably installed with a second-level light guide plate through a damping rotating shaft. The inner wall of the sleeve is provided with a thread structure, and the outer wall of the lamp body is provided with a thread structure. The sleeve is installed on the outer wall of the lamp body through the thread structure. The connecting rod is a cylindrical structure.

[0004] In the above patent, by pulling the first-level light guide plate and the second-level light guide plate, the lighting range, angle and light direction can be adjusted quickly and arbitrarily according to needs, the light concentration can be improved, and the operation accuracy can be indirectly improved. For lighting devices such as the above patent, in order to improve the light concentration effect, it includes multiple groups of light guide plates. However, in the process of light concentration in the above patent, the angles of the light guide plates need to be adjusted one by one. When the number of light guide plates is large, the working intensity will be greatly increased, which is not convenient for the use of this lighting device, and there are certain deficiencies.
