Description
Technical Field
The invention relates to the field of car lamps, in particular to a composite lens, a manufacturing method thereof, a car lamp and a composite lens manufacturing module.
Background
The lens is an important optical component in the automobile headlamp module, and the light condensing performance of the lens determines the sharpness and the light color consistency of the low-beam cutoff. Chromatic dispersion of the lens material can lead to chromatic aberration of the lens: the glass material has lower dispersion, higher refractive index and higher heat-resistant temperature, but the glass lens has high cost and heavy weight; the synthetic resin material has the advantages of low processing cost and light weight, but high dispersion, is easy to cause the blurring and color development of the cut-off line of the low beam, the blurring of the cut-off line can cause dazzling light to the driver of the opposite vehicle, the colored low beam can influence the vision of the driver, and erroneous judgment is caused.
Among them, the achromatic scheme mainly has the following three kinds:
(1) The traditional achromatic scheme is to combine or glue two or more lenses with different dispersion coefficients, and has better optical effect, but increases the number of lenses and the lens production procedure.
(2) Another achromatic scheme is to use a refractive-diffractive hybrid lens, add a diffractive structure on the traditional refractive optical surface by utilizing the negative dispersion characteristic of diffraction, distribute part of diopter of the lens to the diffractive refraction, cancel each other by the negative chromatic aberration of the diffractive refraction and the positive chromatic aberration of the refractive refraction, reduce the overall dispersion of the lens, and thus improve the dispersion problem without increasing the number of lenses.
(3) Two or more synthetic resin composite lenses are obtained by two-color or multi-color injection molding. The optical performance of the scheme is similar to that of the cemented lens, the assembly and the cementing process are saved, and the method has better mass production and lower cost.
In addition, the lenses currently used for the above-described embodiments have the following problems:
(11) The multi-lens combination/gluing scheme increases the number of lenses, resulting in an increased lens weight and a heavy burden on the dimming mechanism. The car lamp has a wider working temperature range (-40 degrees to +120 degrees), the glue joint is easy to crack due to the extremely large temperature difference, the scheme needs to add an assembly procedure, the assembly precision requirement is high, and the efficiency is low.
(21) The disadvantages of the refractive diffractive hybrid lens are as follows: due to the chromatic dispersion of the synthetic resin material, the diffraction structure has different phase modulation amounts for different wavelengths, and when the wavelength of incident light is inconsistent with the design wavelength of the diffraction structure, the diffraction efficiency is reduced, and stray light is formed; when the incident light is a multi-wavelength mixed light, the farther the light wavelength deviates from the design wavelength, the more serious the parasitic light, and the lower the diffraction efficiency.
(31) The two-color disadvantage is as follows:
a. the combination/multicolor injection molding compound lens between different synthetic resin materials has poor performance, is easy to fall off after cooling, needs to glue in advance at the combination part (increasing the working procedure and the cost), or increases the binding force between the synthetic resins through structural design, but has small size and large bending at the connecting structure, is not beneficial to the flowing of the synthetic resins, and is easy to form injection molding defects;
b. different synthetic resins have different coefficients of thermal expansion, and when the temperature difference of the environment is large, the cemented lens is easy to generate stress cracking.
