Description

Technical Field

[0001] The invention relates to the technical field of lamps, and in particular to an annular low-glare mixed light lens and a manufacturing mold thereof. Background Art

[0002] Nowadays, many shopping malls, supermarkets, office buildings, homes and other places use some adjustable color temperature lamps for lighting to meet daily lighting needs. However, the commonly used adjustable color temperature lamps on the market basically use light mixers as the main optical accessories, and conventional light mixers only have a light mixing effect but no dimming effect on light, which will inevitably produce some glare, which will reduce the comfort of the entire environment and have a certain adverse effect on health. At the same time, these stray lights also lead to a decrease in light utilization. Therefore, in order to avoid the shortcomings of the existing technology, it is necessary to improve the existing technology. Summary of the invention

[0007] Furthermore, a circular arc-shaped incident surface protruding upward is provided at the bottom of the circular arc-shaped protrusion.

[0008] Furthermore, the arc-shaped convex strip gradually becomes smaller from the outer side of the lens body to the inner side of the lens body.

[0009] Furthermore, the top of the arc-shaped convex strip is higher than the top of the emergent inclined surface.

[0010] Furthermore, the top of the arc-shaped convex strip is higher than the top of the arc-shaped protrusion.

The rest of the light is irradiated onto the exit inclined surface in the shooting groove and the bottom surface of the arc-shaped protrusion. The light is basically accurately refracted in the concentrated direction through the adjustment of the arc-shaped protrusions, the toothed protrusions and the arc-shaped protrusions. The arc-shaped protrusions can reuse some stray light from the LED light source to make the brightness of the entire mixed light lens more uniform and the visual effect more comfortable. At the same time, it can greatly collect light for utilization. Due to the reduction of stray light, glare will be significantly reduced, the lighting effect is good, the light type is clean and focused, the lamp is soft and not dazzling, and the comfort of the lighting environment is increased.
