    Abstract: A method for calculating the surfaces of optical lenses including the steps of: providing a desired light distribution to be generated with light passing through the lens; deforming a first surface of the lens to generate light source images of different sizes; deforming a second surface of the lens to displace the light source images such that they lie at their highest point directly at or on a light/dark border in a resulting light distribution; determining a quality of the resulting light distribution by a comparison with the predefined light distribution; if the quality lies above a predefined limit value, storing the calculated surfaces for the lens; otherwise, renewed deformation of the first surface; renewed deformation of the second surface; repeating the previous two steps until the quality of the resulting light distribution lies above the limit value; and storing the calculated surfaces for the lens.

    Abstract: An LED vehicle headlamp includes an LED light source, at least one electrochromic device optically coupled to the LED light source, and a collimator positioned between the LED light source and the electrochromic device. The electrochromic device has an alterable light transmission characteristics in response to voltage/current level applied thereto. The collimator is configured for collimating and converging light emitted from the LED light source and directing light into the electrochromic device. When a forward bias voltage/current is applied to the electrochromic device, the visible light transmission of the electrochromic device decreases accordingly to generate a first light intensity distribution pattern, which is a low beam.

  • Publication number: 20140376250
    Abstract: This invention is to provide an in-vehicle interior light unit that protects a base from a thermal damage attributable to a thermal factor and reduces cost. This is achieved by adopting a general-purpose compact bulb cassette which does not have a heat shielding function although the bulb cassette still uses a heat-resistant resin as the material thereof, and the thermal deformation due to the radiant heat from a bulb is prevented by a heat shield plate integrally formed when punch-molding a bus bar, which is formed of a conductive metal member. Thus, the radiant heat from the bulb is blocked by the heat shield plate.
