Abstract
An evaluation device for evaluating mist generation in a light chamber of a vehicle lighting device capable of obtaining a highly accurate result by a bench test. The evaluation device includes a partition wall that partitions a space outside of the lighting device into a front space and a rear space. Further, there is provided a rear space environment setting mechanism for setting the rear space at an environment different from that of the front space. Thus, even if the lighting device is not incorporated into a true vehicle, it is possible to make evaluations of mist generation while the environment in the space outside of the lighting device is maintained so as to be similar to that in a true vehicle.
Claims6
An evaluation device for evaluating mist generation in a vehicle lighting device, the mist being generated in a light chamber of the vehicle lighting device that is composed of a front lens and a lamp body, the lamp body having a vent hole for communicating the light chamber with a space outside of the lighting device, the evaluation device comprising:
- a partition wall that partitions the space outside of the lighting device into a front space and a rear space, wherein the partition wall is positioned at an outer circumferential section of the lighting device;
- a rear space environment setting mechanism that sets the rear space at an environment different from that of the front space;
- and
- a watering mechanism that is adapted to water the front lens, said watering mechanism being arranged in the front space.
