Description
Technical Field
The invention relates to an optical lens, in particular to a thin V-shaped groove optical precision lens, and belongs to the technical field of optical lenses.
Background
Because the light emitting diode has the advantages of small volume, high light emitting power, low pollution and the like, the light emitting diode has become a light emitting source of various electronic products, such as screens of mobile phones, computers, televisions and the like, and the light emitting diode is used as a light energy source. In addition, as the research and development of the light emitting diode are gradually matured, the light intensity emitted by the light emitting diode is gradually increased, so the light emitting diode has wider application as illumination, and is considered to replace the existing light sources such as bulbs, halogen lamps and the like, and the trend of future illumination is considered to be that the lens is required to refract and focus the light rays when the illumination is realized, so the light sources can be fully utilized, but the thin optical lens in the prior art cannot effectively fully utilize the light sources, so the design of the thin V-shaped groove optical precision lens is necessary.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide the thin V-shaped groove optical precision lens, wherein the reflection lens is arranged in the groove to improve the brightness of light, a gap is arranged between the first lens and the second lens, the light can irradiate into the first lens through the gap, and the light source is fully utilized.
In order to achieve the above purpose, the invention adopts the following technical scheme: a thin V-shaped groove optical precision lens comprises a first lens and a second lens.
The surface of the second lens is provided with a groove, the first lens is inlaid in the second lens through the groove, a groove is formed in the first lens, and a reflecting lens is arranged on the surface of the groove.
As a further optimization of the technical scheme, a gap is arranged between the second lens and the first lens of the thin V-shaped groove optical precision lens.
As a further optimization of the technical scheme, the first lens of the thin V-shaped groove optical precision lens is cylindrical with thick upper part and thin lower part.
As a further optimization of the technical scheme, the grooves of the thin V-shaped groove optical precision lens are inlaid on the surface of the wall of the first lens, a plurality of groups of grooves are formed, and each group of grooves can find the other group of grooves which are symmetrical with respect to the center of the first lens.
As a further optimization of the technical scheme, the second lens of the thin V-shaped groove optical precision lens is in a round table shape, the surface of the second lens is provided with the convex blocks, and the convex blocks are provided with a plurality of groups.
Due to the application of the technical scheme, compared with the prior art, the invention has the following advantages:
according to the thin V-shaped groove optical precision lens, the gap is formed between the first lens and the second lens, so that the light source can irradiate the inside of the first lens from the gap, the utilization rate of the light source is increased, the groove is inlaid in the surface of the wall of the first lens, the reflecting lens is arranged in the groove, the reflectivity of light is improved, and the light entering the eye is brighter.
