Description

Technical Field

[0001] The present invention relates to the technical field of optical lens preparation, and particularly to a rotatable angle industrial and mining lamp lens applicable to large-angle and high-power lighting products. Background Art

[0002] Industrial and mining lamp lighting is closely related to industrial production. LED industrial and mining lamps have gradually come into people's view with advantages such as directional light emission, low power consumption, good driving characteristics, fast response speed, high seismic resistance, long service life, and environmental friendliness. Therefore, LED industrial and mining lamps will become the best choice for lighting energy-saving transformation in the field of traditional large industrial plant lighting, and it is also the general trend.

[0003] The beam angles (i.e., light-emitting angles) of conventional industrial and mining lamps have multiple angles such as 60 degrees, 85 degrees, 105 degrees, and 120 degrees. In order to meet the angle requirements of different lamps, lenses with different angles need to be designed, and lenses with different angles are installed according to different lighting requirements. The lenses of conventional industrial and mining lamps are all composed of convex lenses that rotate in a ring. Industrial and mining lamp lenses with different angles are designed according to different curvatures of the convex lenses, so as to meet the angle requirements.

[0004] At present, most LED industrial and mining lamp fixtures on the market have a fixed beam angle. There are also fixtures with multiple-angle lenses made on one fixture, and different beam angles are achieved by lighting the light sources corresponding to different-angle lenses or through different installation methods. For example, a double-circle mosquito coil plate structure is adopted. One circle is designed as a 60-degree beam angle structure, and the other circle is designed as a 120-degree beam angle structure. A number of LED chips need to be arranged in the cavities formed by the light-incident surfaces of the two circles. During installation, according to different scenario requirements, the 60-degree or 120-degree angle structure is selected for installation. When in use, only the LED chips corresponding to the angle can be lit, so as to meet the requirement of different beam angles for different scenarios. Once this structure is installed and fixed, the beam angle remains unchanged. No matter which angle installation structure is selected, the lens structure and LED chips at the other angle are wasted.

[0005] The current solutions on the market need to cover the entire lens substrate with LED chips, which will cause waste of LED chips and lens structures. The beam angle can only vary within 2 or 3 fixed preset angles, and the beam angle cannot be changed after installation. Summary of the Invention

[0006] To solve the problem that for the existing LED industrial and mining lamps, whether they are designed with a single angle or multiple angles, the beam angle remains fixed after installation and cannot be adjusted steplessly within a certain angle range, the present invention provides a rotatable angle industrial and mining lamp lens. By providing multiple annular light-transmitting bands, multiple light-transmitting areas with different angles are provided on the same annular light-transmitting band, and light-transmitting areas with gradually changing angles are provided between the light-transmitting areas with different angles. Moreover, the light-transmitting areas corresponding to the same angle on each adjacent two annular light-transmitting bands are arranged staggeredly. The optical lens and the substrate installed with the LED chip are set to be rotatably connected. After installation, by rotating the lens or the substrate, the beam angle can be changed, achieving the purpose of meeting the requirements of multiple beam angles with the same optical lens and being able to change the angle steplessly within a certain angle range.

[0007] To achieve the above object, the present invention provides a rotatable angle industrial and mining lamp lens, which includes a substrate, an LED chip, and an optical lens. The optical lens is provided with multiple sequentially connected annular light-transmitting bands.
