  • Patent number: 9599563
    Abstract: An LED inspection lamp has plurality of LED sources for emitting electromagnetic radiation at different peak wavelengths for causing visible fluorescence in different leak detection dyes. A lens is associated with each LED. Radiation passing through lenses is superimposed in target area at target distance. Another LED inspection lamp has plurality of LEDs emitting electromagnetic radiation at a peak wavelength. A lens adaptor has lens housing for attachment to LED inspection lamp with a single LED for causing visible fluorescence, and a lens. Substantially all of the radiation from the LED passes through the lens and is focused in a target area at a target distance from the lenses. LED spot lights have a similar configuration. The LEDs may produce white light from distinct LEDs or from white LEDs. The light may be a flashlight or fixed spot light.

  • Patent number: 9546766
    Abstract: The present invention is directed toward light module for a motor vehicle headlamp that has numerous light sources, a primary lens, and a secondary lens. The primary lens is configured to collect light emitted from the light sources, and to convert this light to an intermediate light distribution having the form of a closed, illuminating surface area. The secondary lens has an object-side focal length, and the primary lens and the secondary lens are disposed such that the intermediate light distribution lies, at a spacing of this focal length, in the beam path in front of the secondary lens. The light emission surfaces of the light sources are separated from one another by spacings lying between them, and the primary lens is configured to distribute the light emitted from the light sources such that the spacings in the intermediate light distribution can no longer be perceived.
