Problems solved by technology

[0003] In the prior art, the shape of the LED lens (LENS) is a traditional arc shape, and the LED chip is a plane light source. In this way, after the LED light source undergoes an optical treatment through the lens, the light-emitting angle is less than or equal to 120°. In some occasions where large-angle LEDs are required, the LED light source needs to be optically designed more than twice. In this way, not only the number of LED parts increases, the structure is complicated, but also the processing technology becomes complicated, which makes the cost of the LED high. After optical treatment, the luminous flux of LED light source is reduced

Abstract

The invention relates to the technical field of light emitting diodes (LEDs), and discloses a large-angle LED and an LED lamp. The large-angle LED comprises a light source piece and a special-shaped optical device for refracting and reflecting the light emitted by the light source piece for many times, wherein the light source piece is placed in the special-shaped optical device, and the special-shaped optical device is provided with a plurality of light control faces and a plurality of light reflection faces. Compared with the prior art, the special-shaped optical device can refract and reflect the light emitted by the light source piece for many times, so that a unidirectional irradiation beam or a surface light source can achieve the irradiation effect of a third-dimensional luminous light source, and the luminous angle of the unidirectional irradiation beam or the surface light source is further more than 180 degrees; and the large-angle LED has simple structure, low cost and high light flux.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a large-angle LED and an LED lamp. Background technique [0002] In the context of rising concerns about global energy shortages, saving energy is an important issue facing us in the future. LED is called the fourth-generation lighting source or green light source. It has the characteristics of energy saving, environmental protection, long life and small size. It can be used in various indications, displays, decorations, backlights, general lighting and urban night lights. A new type of green light source product is widely used in various fields in real life, and it is bound to be the trend of future development. [0003] In the prior art, the shape of the LED lens (LENS) is a traditional arc shape, and the LED chip is a plane light source. In this way, after the LED light source is optically processed through the lens, the light angle is less than or equal to 120°. In some occasi...
