Problems solved by technology

This method affects the judgment of the sunlight angle, and most of them manually adjust the distance and relative position between the test piece and the light source
There are also some simulated focused light sources that use full coverage (the light emitted by the light source covers the entire test piece). Since the light source is directly irradiated or fully covered, and the light source is not parallel light but a divergent light source, the focusing angle of the convex mirror The test is not accurate, and the irradiation time and length are different, which will also affect the judgment of the focusing result

Embodiment 1

[0039] A test device for simulating the focused burning of sunlight, such as Figure 1~4 As shown, it is used for the whole lamp assembly with a lens, including an arc track 1 and a test turntable 3. The arc track 1 has a parallel light source 2 that can move along the arc track 1. The test turntable 3 is used to fix the whole lamp to be tested. The lamp assembly 4 is rotatably arranged in the arc-shaped track 1, and the rotation plane is perpendicular to the plane where the arc-shaped track 1 is located; the parallel light source 2 is used to emit parallel light beams and form on the mask 42 of the whole lamp assembly 4 to be tested The light spot X, the parallel light beam points to the lens optical center 41 of the whole lamp assembly 4 to be tested during the movement of the parallel light source 2 along the arc track 1 .

[0040] In this example, if figure 1 As shown, the arc track 1 is semicircular, vertically arranged, and both ends are located on the same horizontal p...

Abstract

The invention relates to a test method for simulating sunlight focusing-induced scorching. The test method is used for a whole lamp assembly with a lens. The test method is characterized by comprising the following steps that: (a) a test device is provided; (b) a whole lamp assembly to be tested is fixed on a test rotary table according to a loading direction, under a condition that the rotation angle of the test rotary table is fixed, a parallel light source moves in a range of 0-90 degrees relative to the whole lamp assembly to be tested along an arc-shaped rail, an area scanned by a light spot on a mask is a light spot scanning area, and the whole mask is divided into a plurality of scanning areas according to different rotation angles of the test rotary table; and (C) the rotation angle of the test rotary table is adjusted, the light spot scanning areas are scanned from one end to the other end of the whole lamp assembly to be tested. Compared with the prior art, the method is ingenious in design, can accurately control focusing time in a test process, simulate actual solar moving orbits, obtain accurate focusing positions and angles, and keep the stability of irradiation energy more easily.

Description

technical field [0001] The invention relates to the technical field of vehicle lamp detection, in particular to a test method for simulating focused burning of sunlight. Background technique [0002] The car light lens reflects the scattered light of the bulb into a parallel beam, which greatly enhances the luminosity, hundreds of times or even thousands of times, ensuring sufficient lighting within the range of 150-400M in front of the car, and there is a clear dividing line between light and dark, which can Clearly illuminate the road surface, and the light can show the effect of low left and right high. In the state of high beam and low beam, the light will not diverge, but the lighting effect on the ground is very good, it will not cause glare, and will not affect the opposite side Therefore, the motor vehicle headlight with lens structure has a higher market share by virtue of its superior performance in appearance, size and performance. [0003] However, due to the st...
