    摘要: An apparatus having a light source, a reflector, and a light pipe is disclosed. The light source includes a plurality of LED dies arranged in an array along a first direction, each LED die emitting light in a second direction. The light pipe includes a layer of transparent material having a top surface, a bottom surface, and an edge surface. The reflector reflects light from the LED dies traveling in the second direction into the edge surface of the light pipe such that a portion of the light is reflected by the top and bottom surfaces of the reflector. In one embodiment, the reflector redirects light leaving the LED dies within a predetermined cone of angles about the first direction into the light pipe such that the light in that predetermined cone of angles is totally reflected by the top surface of the light pipe.

    摘要: A light emitting device has a light emitting diode (LED), a reflector cup, and one or more adjustment mechanisms to control the intensity profile of light emitted from the light emitting device. The reflector cup has a base and a sidewall extending outward from the base. A base adjustment mechanism controls the total amount of light reflected from the base and into the beam of light emitted from the light emitting mechanism by controlling the aggregate reflectivity of the base. A sidewall adjustment mechanism controls the angle of the sidewall relative to the base. A vertical adjustment mechanism vertically raises or lowers the LED relative to the base.

    摘要: Disclosed are systems and methods which provide an illuminator configuration in which an optical element is provided integral with a reflector component. Embodiments provide an LED encapsulation optical element having a boundary with a surrounding medium, such as air, which avoids or minimizes total internal reflection phenomena. Such an LED encapsulation optical element is formed integral with a reflector component in order to ensure proper relative placement of the LED light source, optical element, and reflector component and/or to facilitate rapid and predictable mechanical assembly of an illuminator. Plated through holes may be disposed in a substrate beneath the LED light source to dissipate heat from the LED light source, prolonging the life of the LED light source and/or the encapsulation material.

    摘要: A lighting system includes multiple lighting elements, a light guide, and a first selective wavelength reflective element for mixing light outside of the light guide. The lighting elements include a first lighting element having a first wavelength. The light guide receives light from the lighting elements. The first selective wavelength reflective element is positioned between the first lighting element and the light guide to partially transmit light of the first wavelength to the light guide, and to partially reflect light of the first wavelength. Partially reflecting light away from the light guide allows a fraction of the light to be mixed with another color of light prior to entering the light guide. By mixing multiple colors of light outside of the light guide in this manner, discoloration of the LCD panel may be limited or eliminated. Additionally, oversizing the diffusion panel may be limited or eliminated.

    摘要: A virtual display with motion synchronization (“VDMS”) device using one or more arrays of light sources for displaying messages. The VDMS device may include a motion sensor to detect and measure movement of the VDMS device, and synchronization circuitry configured to synchronize the light emission of the individual light sources in the arrays with the movement of the VDMS device. The VDMS device may also include a self-contained power source and a control unit and interface that allow the user to program the messages that are displayed by the VDMS device, as well as memory that stores user messages.
