Abstract

The invention provides an LED strip lens and LED strip lamp with even luminosity of 180 degrees. The upper surface of the LED strip lens comprises two arc-shaped curve surfaces which are symmetrical to each other. The middle part of the lower surface of the LED strip lens is provided with a semi-elliptic groove, and the two side ends of the LED strip lens are provided with clamping parts. The LEDstrip lens and LED strip lamp with even luminosity of 180 degrees have the beneficial effects that by arranging the shape of the upper surface of the LED lens as the two arc-shaped curve surfaces symmetrical to each other, the middle part of the lower surface of the LED strip lens as the structure of semi-elliptic groove, and according to the refractive index and thickness distribution of lens materials, ray of light emitted by LED emitting components in the lens can be reflected and refracted, and finally, the uniform distribution of luminosity at sectional positions of a box body is achieved. The structure of a second LED strip lens is formed by integrating the LED strip lens with a strip seat of the LED lens, the LED emitting components are arranged in the structure, the leakproofness is improved, water vapor is prevented from entering the structure, and the service life of the emitting components on a LED light panel is prolonged.

Description

technical field [0001] The invention relates to the technical field of uniform distribution structure of luminosity of LED lamps, in particular to a 180-degree uniform LED strip lens and LED strip lamp. Background technique [0002] LED lamps are installed in cabinets such as freezers to illuminate the inside of the cabinet and facilitate the picking and placing of items in the cabinet. At present, the uniformity of the luminous brightness of the LED lights installed in the box is not good. In places such as the box body, the distance from the LED lights is brighter, and the distance from the LED lights is darker. This makes the lights in refrigerators and other boxes Inconsistency in brightness will affect the user's visual experience, and it will be inconvenient to pick and place items located in dark places. In addition, due to the gap between the lens and the mounting seat of the LED lamp, the sealing is not good, and water vapor is easy to enter, which has a negative i...
