Object detecting apparatus having hydrophilic light radiating window
First Claim
1. An object detecting apparatus for detecting an object, the apparatus comprising:
- a case having a light radiating window and a light receiving window, the windows being made of light transmitting material;
a light radiation unit disposed in the case for radiating a light toward an outside of the case through the light radiating window; and
a light receiver unit disposed in the case for receiving the light reflected by the object through the light receiving window, wherein the light radiating window has a hydrophilic layer on an outer surface thereof exposed to an outside of the case.

Abstract
An object detecting apparatus comprises a case, a light radiation unit and a light receiver unit. The case has a light radiating window and a light receiving window. The light radiating window has a hydrophilic layer on the outermost surface of the light radiating window. The hydrophilic layer restricts water droplets remaining on the light radiating window from functioning as light collecting lenses, so that the light is radiated outward without being scattered by the water droplets. Specifically, the light radiating window further has a glass substrate at an innermost side and a photo-catalyst layer between the glass substrate and the hydrophilic layer. The hydrophilic layer is made of silicon dioxides.
