Problems solved by technology

However, after the assembly of the vehicle is completed, the lamps are tested. The test time is relatively late. If improvements are required after the test, it is easy to delay the launch date of the entire product.

Embodiment 1

[0051] Such as figure 1 and figure 2 As shown, this application discloses a method for testing the anti-fogging performance of lamps. An ultrasonic atomization method is adopted to obtain an atomization area. After the lamp to be tested is individually powered on, the lamp is placed into the atomization area and the lamp is turned on to achieve the preset value. After setting the length of time, observe the condition of the condensation water on the lampshade to judge whether the anti-fogging performance is qualified.

[0052] The anti-fogging performance of the lamp to be tested in this application at a specific ambient temperature and humidity allows the lamp to be tested before assembly, which facilitates optimization and improvement of the lamp in advance, and ensures that the product is launched on time. In addition, this application can test the vehicle lights in high beam and low beam modes respectively. This application can first observe when the first preset time is rea...

Embodiment 3

[0107] Such as figure 1 and Figure 4 As shown, this application discloses a method for testing the anti-fogging performance of lamps. An ultrasonic atomization method is adopted to obtain an atomization area. After the lamp to be tested is individually powered on, the lamp is placed into the atomization area and the lamp is turned on to achieve the preset value. After setting the length of time, observe the condition of the condensation water on the lampshade to judge whether the anti-fogging performance is qualified.

Abstract

The invention discloses a testing method for the anti-fogging performance of a lamp. The testing method comprises the following steps that an atomization area is obtained by adopting an ultrasonic atomization method; a to-be-detected lamp is put into the atomization area and turned on after being connected to a power supply separately; and after a preset time, the condensed water drop attachment condition of a lampshade part of the lamp is observed, and whether or not the anti-fogging performance is qualified is judged. According to the testing method, by means of the anti-fogging performanceof the to-be-detected lamp at specific environmental temperature and humidity, a car lamp can be tested before being assembled, therefore, the car lamp can be conveniently optimized and improved in advance, and on-time marketing of the product is guaranteed.

Description

Technical field [0001] This application relates to the technical field of lamp detection, and in particular to a method for testing the anti-fogging performance of lamps. Background technique [0002] When the temperature difference between the inside and outside of the lampshade is too large, the water molecules in the humid air will be sucked into the cavity of the lamp group through the rubber vent tube or vent of the lamp, and condense on the surface of the inner lampshade, causing the lamp to fog up. . Fog in the car lights will not only affect the light transmittance of the car lights, make it difficult to see the road conditions, but also easily form astigmatism, causing dazzling light pollution to vehicles in the opposite direction, and worse, it will cause corrosion to the related electrical components of the lamp set , Has laid a huge hidden danger to driving safety. [0003] In the prior art, in order to avoid safety accidents caused by fogging of vehicle lights, the s...
