Description
Technical Field
The utility model relates to a vehicle lighting device especially relates to a high bright lighting device of central authorities for car light.
Background
The safety lighting device car light is inevitably needed to be used in the driving process of the vehicle, the car light is of great importance to the safety of driving at night, and the lighting range of the car light is the key point of driving safety. Along with the popularization of the LED light source, the modeling of the car lamp module is more and more abundant and can provide more light shape adjusting spaces, and the integral illumination intensity can meet the use requirement. When the central brightness of illumination needs to be improved, a light module is usually additionally arranged to provide supplementary illumination for the central area, on one hand, the extra light module easily shields the existing light to influence the light utilization rate, and on the other hand, the supplementary illumination part and the central highlight area are difficult to transit uniformly.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned prior art defect, the utility model discloses a task lies in providing a central authorities high bright lighting device for car light, improves light utilization ratio, guarantees the even transition of light shape luminance.
The utility model discloses technical scheme is such: the central high-brightness lighting device for the car lamp comprises an LED light source, a gradually-enlarged reflection cup, a first lens and a second lens, wherein the LED light source is arranged at a small-diameter end of the gradually-enlarged reflection cup, the second lens is arranged in front of a large-diameter end of the gradually-enlarged reflection cup, the first lens is arranged at the small-diameter end of the gradually-enlarged reflection cup and is positioned in front of the LED light source, the first lens is a single-side convex lens, and one side of the plane of the first lens faces towards the LED light source and is flush with the end face of the small-diameter end of the gradually-enlarged reflection cup.
Further, the second lens is a single-sided convex lens, and one planar side of the second lens faces the first lens.
Further, the divergent reflecting cup, the first lens and the second lens are coaxially arranged.
Further, the diameter of the flat surface side of the first lens is smaller than the diameter of the small-diameter end of the divergent reflecting cup.
Furthermore, an aluminum-plated reflecting layer is arranged on the inner wall surface of the gradually-expanding reflecting cup.
Compared with the prior art, the utility model the advantage lie in:
the light emitted by the LED light source is gathered to the center by the first lens, the light utilization rate is improved by matching with the gradually-expanded reflection cup, the central brightness is improved, light shielding cannot be formed, the overall optical efficiency is high, light transition is uniform, and the structure is simple and compact.

Detailed Description
The present invention will be further described with reference to the following examples, which should not be construed as limiting the invention.
Referring to fig. 1 to 3, a central high-brightness lighting device for a vehicle lamp according to the present embodiment includes an LED light source 1, a gradually expanding reflective cup 2, a first lens 3, and a second lens 4, where the LED light source 1 is a commonly used three-chip light source and is located at a small diameter end of the gradually expanding reflective cup 2, the gradually expanding reflective cup 2 is made of opaque PC or PMMA, and an aluminum-plated reflective layer is disposed on an inner wall surface of the gradually expanding reflective cup 2 to improve a reflectivity.
The first lens 3 is a single-sided convex lens and is made of silica gel or glass, and one side of the plane of the first lens 3 faces the LED light source 1 and is flush with the end face of the small-diameter end of the gradually-enlarged reflection cup 2. The diameter of one side of the plane of the first lens 3 is slightly smaller than that of the small diameter end of the divergent reflection cup 2, and an annular gap is reserved between the first lens 3 and the small diameter end of the divergent reflection cup 2. The second lens 4 is also a single-sided convex lens and is made of silica gel or glass, the second lens 4 is arranged in front of the large-diameter end of the gradually-expanding reflecting cup 2, and one side of the plane of the second lens 2 faces the first lens 3. The central axes of the divergent reflecting cup 2, the first lens 3 and the second lens 4 are coaxially arranged.
Most of light of the LED light source 1 is condensed by the first lens 3, part of the light is directly irradiated to the second lens 4, the other part of the light is irradiated to the inner wall of the gradually enlarged reflection cup 2, the small part of the light of the LED light source 1 is directly irradiated to the inner wall of the gradually enlarged reflection cup 2, the inner wall of the gradually enlarged reflection cup 2 reflects the light and then irradiates to the second lens 4, all the light is shaped by the second lens 4 to form emergent light, the brightness of the central area of the final light is the highest due to the condensation of the first lens 3, and the light reflected by the reflection cup 2 after being condensed by the first lens 3 and directly reflected by the reflection cup 2 forms uniform peripheral light on the periphery of the central area.
