Detailed ways

The implementation of the present application will be described in detail below with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects.

Please refer to FIG. 1 . FIG. 1 is a perspective view of a reflective bowl of a lens headlight according to an embodiment of the present application. As shown in the figure, a reflector bowl for lens headlights includes a bowl wall 10, the bowl wall 10 has a concave bowl surface 20 and a first bowl mouth 30 and a second bowl mouth 40 located on both sides of the bowl surface 20, the bowl surface 20 has a reflective layer 80, and the reflective layer 80 is configured as a light-reflecting composite material; the outer flange portion 50 is arranged on the outside around the first bowl mouth 30; the inner flange portion 60 is arranged on the inner side around the second bowl mouth 40; And a plurality of mounting holes 70 disposed on the outer flange portion 50 . In one embodiment of the present invention, the bowl wall 10 has a relatively connected first bowl mouth 30 and a second bowl mouth 40, the aperture of the second bowl mouth 40 is smaller, so as to install a light bulb, so that the light bulb can be used as a light source to radiate light and irradiate to The bowl surface 20 is acted by the reflective layer 80 to generate reflection of light, which is transmitted to the lens through the first bowl mouth 30 to realize the effect of the low beam and high beam of the vehicle. Among them, the reflective layer 80 is made of a light reflective composite material, which is more uniform in reflected light compared with the spray paint and aluminum plating on the market, and is not easy to wear and fall off, reduces light loss, and has strong practicability.

Please continue to refer to FIG. 2 , which is a front view of the lens headlight of the embodiment of the present application. As shown in the figure, the bowl surface 20 includes an opposite first curved surface 21 and a second curved surface 22, and the first curved surface 21 and the second curved surface 22 are connected through a third curved surface 23; wherein the first curved surface 21 and the second curved surface 22 have the same structure, and the width of the third arc surface 23 is set to 10mm. In this embodiment, the light bulb is installed through the second bowl mouth 40 and is arranged in a column shape, and the light source emitted by it will emit to the surroundings, and the first curved surface 21 and the second curved surface 22 are transitionally connected through the third curved surface 23, Avoiding the direct integral formation of a concave spherical surface, relatively reducing the outgoing distance of light, making the first bowl mouth 30 tend to be elliptical, reducing light loss and concentrating reflection. In addition, the width of the third curved surface 23 is close to the width of the light bulb, and is set to 10mm, which is slightly smaller than the width of the light bulb. On the premise of smoothly connecting the first curved surface 21 and the second curved surface 22, the distance between the two curved surfaces is appropriately reduced, and the reflected light to the lens is more uniform. , which is more convenient to use.

It is worth mentioning that, in the present invention, the thickness of the outer flange portion 50 is set at 1.5 mm to 2 mm, and the thickness of the inner flange portion 60 is set at 1 mm to 1.5 mm. In this embodiment, when the thickness of the outer flange portion 50 is 1.5 mm or 2 mm, it can maintain relatively stable rigidity, and can maintain firm stability when connecting the lens holder through the mounting hole 70 . The inner flanging portion 60 needs to support the light bulb and expose it as a plug at the same time. Therefore, for the convenience of heat dissipation, its thickness should be slightly smaller. When it is set to 1mm, the heat dissipation is strong and the stability is just; The heat dissipation and stability are more balanced and more applicable.

The light reflective composite material provided by the invention includes barium sulfate, titanium dioxide and a binder. The combination of the three has the effect of light reflection. Barium sulfate is used as an extender pigment in paints and plays an important role in improving the thickness, wear resistance, water resistance, heat resistance, surface hardness and impact resistance of coatings. In addition, barium sulfate has high reflectivity for visible light in the wavelength range of 300-400 microns, which can protect the paint film from photoaging, and is an effective and cheap white inorganic light stabilizer. Because of its low oil absorption and high loading, it can keep the cost of coating down. In addition, titanium dioxide has the best opacity, whiteness and brightness, and has better performance. It also has a better shielding effect on non-visible light such as ultraviolet rays. Therefore, after coating on the bowl wall 10, it can prevent the photochemical reaction of the bowl surface 20, effectively Reduce light loss. Adhesive bonds the two for convenience and utility.

In one embodiment of the present invention, for the content of the light-reflecting composite material, the weight ratio of barium sulfate to titanium dioxide is set between 9:1 and 4:6, and the size of the lens headlight is properly adjusted according to the power of the bulb , simple and easy to operate, and the present invention does not repeat them in detail. In addition, the adhesive is set to a resin with a Shore hardness of 20 or less, which is soft and practical, and it is convenient to bond barium sulfate and titanium dioxide. Finally, the reflective layer 80 has a thickness of 15 μm to 200 μm to achieve ultra-thin processing and reduce light loss.

Next, please continue to refer to FIG. 3 , which is a schematic diagram of a reflective layer 80 according to an embodiment of the present application. The reflective layer 80 is provided by laminating the barium sulfate layer 81 with the titanium dioxide layer 82, the thickness of the barium sulfate 81 layer is more than 10 μm, the thickness of the titanium dioxide layer 82 is more than 5 μm, and the total thickness of the two layers is less than 300 μm. In one embodiment of the present invention, the titanium dioxide layer 82 is directly laminated on the barium sulfate layer 81, which avoids the mixing process in other embodiments, improves work efficiency, and does not need to mix formulas specially. On the bowl wall 10, the coating is convenient and the processing is fast, which greatly improves the production efficiency and reduces the cost. At the same time, ensure that the total thickness of the two layers is less than 300 μm, the reflection is uniform, and the light loss is relatively small.
