Vehicle lamp lens sunlight focus point detection device and use method thereof

Abstract

The invention belongs to the technical field of vehicle lamp detection, in particular to a vehicle lamp lens sunlight focus point detection device and a use method thereof. The device comprises a base. A horizontal rotary bench is rotatably connected to the base. A lens adjustment mechanism and a sample piece adjustment mechanism are arranged on the horizontal rotary bench. The lens adjustment mechanism comprises a first support and a first precision rotary bench. The first support is fixed to the horizontal rotary bench. A clamping device is installed on the rotary part of the first precisionrotary bench. The sample piece adjustment mechanism comprises an elevating bench and a second precision rotary bench. The bench seat of the second precision rotary bench is fixed to the elevating bench. A fixed plate is fixed on the rotary part of the second precision rotary bench. The beneficial effects are that positions of reflection focus points and refraction focus points can be calculated;the calculation is precise; it is convenient to carry out analysis to obtain the safe distance where the lens is prevented from burning lamp materials; and after a thermal imager tests the reflectionfocus points and the refraction focus points, a precise and unique temperature value can be obtained.

Description

technical field [0001] The invention belongs to the technical field of vehicle light detection, and in particular relates to a vehicle light lens solar focus point detection device and a use method thereof. Background technique [0002] With the rapid development of automotive lamp technology, compared with traditional lamps, the light shape of the lens is the most standard, with obvious light and dark cut-off lines, and has the advantages of uniform brightness, strong penetrating power, and small light loss. The lens module is more and more popular. More and more models are used. However, during the use of the lamps, it was found that some lamps had ablation of the peripheral parts of the lens. After research, it was found that when the car was parked at a certain angle, after the sunlight was refracted and reflected by the lens, a gap was formed on or around the parts. Focal spots lead to temperature concentration and ablation of components, causing immeasurable losses to...
