    摘要: A flashlight that generates a flashlight beam to illuminate an object at a selectable distance from the flashlight by imaging a uniformly bright pattern of light onto the object. A light modifying component can be used to manipulate the pattern of light into particular shapes and images. In one embodiment, light from a light source is coupled into a light pipe. The light is homogenized as it travels along the light pipe. The light exits the light pipe with a more uniform intensity than when it entered. The light exiting the light pipe is then reimaged by an imaging lens onto an object. Yet in other embodiments, one or more lens arrays having two or more lenlets are used to homogenize the light originating from the light source.

    摘要: A flashlight that utilizes an array of one or more light-emitting diodes (LEDs) as a light source, and a light pipe as a light homogenizer to generate a light beam capable of forming a uniformized light distribution at a given distance from the flashlight is disclosed. The LEDs may be all the same color, or some or all may be different colors. A switch, coupled to switching electronics coupled to the LED array, is used to change the state of the LED array to create a variety of different types of light beams, each of which provides relatively uniform and bright illumination at a given distance from the flashlight, wherein the given distance is selectable by adjusting an adjustable imaging lens.
