Background
With the rapid development of light source technology, light sources used in automotive lamps are also rapidly developed from halogen light sources to LED light sources. Because the LED light source is small and the luminance value is high, the requirements on the mounting precision of parts such as a reflector, a lens and the like and the LED are high.
Further, in a broad sense, the optical member for a vehicle lamp includes a light source (such as an LED light source, a laser light source, etc.), a primary optical element (such as a reflector, a condenser, etc.), a secondary optical element (such as a lens, etc.), and an assembly member (such as a heat sink, a lens holder, etc.) for positioning and mounting these parts, and the positions and assembly accuracy of the above parts with respect to each other have a great influence on the optical performance of the vehicle lamp product.
In actual production, a traditional positioning and assembling method for an optical element of a vehicle lamp generally selects one component as a reference part, and the other components matched with the component are used as assembling parts. Specifically, taking the assembly of the reflection structure as an example, a pin 1-1 is designed on a heat sink 1 (a reference part), a hole 2-1 (see fig. 1) is designed on a reflector 2 (an assembly part), and the reflector 2 is positioned and mounted on the heat sink 1 by pin-hole fit, as shown in fig. 2. The assembly process can limit the freedom of movement and the freedom of rotation of the assembly parts, and realize positioning.
With the continuous development of the technology, the traditional assembling mode is more and more difficult to meet the requirement of higher and higher vehicle lamp performance on the assembling precision of the optical element. This is because, first, the fitting accuracy between the parts is completely determined by the dimensions of the pin and hole positions and the dimensions of the part shapes, whereas in the art, the manufacturing tolerance of the pin is typically ± 0.05mm according to the industrial design and manufacturing capability, and this dimension is difficult to guarantee in the mass production process; secondly, as shown in fig. 1, the radiator is provided with a plurality of pins, the relative position degree of each pin is provided, and the general tolerance is also +/-0.05 mm, so that the assembly precision is difficult to guarantee after the reflector is arranged on the radiator, if the assembly precision needs to be improved, the pins need to be smaller in size tolerance or smaller in position tolerance, but the radiator is generally a die-casting piece, the difficulty of processing the high-precision pins on the radiator is high, once the processing is wrong, the parts are scrapped, the manufacturing and assembly cost is high, and the production efficiency and the economy are not satisfied; in addition, if the shape and the size of the reference part are deviated during preparation, the matching of the reference part and the assembly part is influenced, so that the quality of the whole product fluctuates, and the quality consistency of the products in the same batch is poor.
