Luminescent lamp body collector lens structure and corresponding lighting device

Abstract

The invention relates to a luminescent lamp body collector lens structure which comprises a lens front end face and a lens rear end face opposite to the lens front end face, wherein the lens structure is a single-piece composite Fresnel lens with a smooth surface. The invention further comprises a lighting device with the lens structure. According to the luminescent lamp body collector lens structure adopting the structure and the corresponding lighting device, a Fresnel refraction area, a convex lens refraction area and a ripple refraction area are arranged on the lens front end face, and an outer edge internal refraction area, a convex refraction area and a total reflection area are arranged on the lens rear end face, so that most of incident lights can be effectively diffused, mixed and refracted; and the other part of lights are reflected, refracted and redirected to focus into a light beam. The luminescent lamp body collector lens structure is simple and practical in structure, economic and practical, as well as stable and reliable in working performance, can adjust width and angle of the focused beam and scattering mixing degree of lights with different colors according to the requirements, is wider in the application range, and brings great convenience for work and life of people.

Description

technical field [0001] The present invention relates to the field of luminous lighting, in particular to the technical field of luminous lighting equipment, in particular to a light-emitting lamp body focusing lens structure and a corresponding lighting device. Background technique [0002] With the continuous progress of human civilization and the continuous development of science and technology, lighting devices have long been widely known. In general, this type of lighting device includes a housing and a light emitting component arranged in the housing. [0003] With the advancement of technology, LEDs have been able to provide enough light energy for lighting purposes. In order to reduce energy consumption for lighting, reduce carbon dioxide emissions, and promote the continuous advancement of the alternative light source market, LED light sources have been used to replace incandescent lamps and halogen lamps. It is the trend of the times. What consumers need is product...

AI Technical Summary

Problems solved by technology

[0008] However, this kind of light has the defect of insufficient light discretion, especially in the spot position (spot position), which is mainly because in this case, only a relatively small spatial angle range in the spot position is covered by the Fresnel lens due to

[0009] At the same time, the conventional Fresnel lens itself cannot achieve the effect of scattering and mixing light of different colors, so it cannot be applied to various occasions that have specific requirements for light sources and light beams
