Description

Technical Field

[0001] The utility model relates to the technical field of LED lampshades, in particular to an efficient light-collecting LED compound-eye lampshade. Background Art

[0002] Generally, LED lamps are equipped with lampshades to improve the lighting effect. After a period of use, the lampshades may be dusty and dirty, which may affect the lighting effect. Some LED lamps are installed at high places. Users need to remove the lampshades when cleaning them. However, the lamp body and lampshades are located at high places, which makes it inconvenient for users to remove and clean them. They need to use tools such as ladders, which is inconvenient.

[0003] Moreover, in the prior art, the focusing effect can be improved by using a fly-eye lens array. The specific principle is that the light beam parallel to the optical axis passes through the first lens and is focused at the center of the second lens. The first row of fly-eye lenses intersects the light source to form multiple light source images for illumination. Each small lens of the second row of fly-eye lenses overlaps the small lens of the first row of fly-eye lenses and forms an image on the illumination surface. Since the first row of fly-eye lenses divides the entire wide light beam of the light source into multiple fine light beams for illumination, and the unevenness of the vertical axis of each fine light beam is compensated due to the mutual superposition of the fine light beams in symmetrical positions, the light energy in the entire aperture is effectively and evenly utilized. The light spot emitted from the second row of fly-eye lenses is focused on the illumination surface through a condenser. In this way, each point of the light spot on the illumination surface is illuminated by the light emitted from all points of the light source. At the same time, the light beams emitted from each point on the light source intersect and overlap within the same field of view on the illumination light spot, so a uniform illumination area is obtained. The compound eye lens used can be made of plastic or glass, but the compound eye lens is generally fixed on the lamp body, so when the lens or the condenser is dirty or damaged, it is generally inconvenient to quickly disassemble and install it, which is quite inconvenient.
