Abstract
A failure determination system for a lighting apparatus determines whether a reflection unit has failed. In particular, the reflection unit forms a projected image by reflecting off light emitted from a light source. The system provides the normalization of the reflection unit and enables to maintain the visibility of the projected image.
Claims15
A failure determination system for a lighting apparatus, the failure determination system comprising:
- a light source unit provided in a housing and configured to emit light;
- a reflection unit, wherein the light emitted from the light source unit is incident on the reflection unit, and the reflection unit is configured to generate a projected image by reflecting the incident light selectively based on a reflection angle;
- an optical sensor spaced apart from the reflection unit in the housing and configured to sense an amount of incident light;
- and
- a controller configured to control the reflection unit and determine whether the reflection unit has failed, based on the amount of the incident light sensed by the optical sensor during failure determination.
