摘要： Individual side-emitting LEDs are separately positioned in a waveguide, or mounted together on a flexible mount then positioned together in a waveguide. As a result, the gap between each LED and the waveguide can be small, which may improve coupling of light from the LED into the waveguide. Since the LEDs are separately connected to the waveguide, or mounted on a flexible mount, stress to individual LEDs resulting from changes in the shape of the waveguide is reduced.

摘要： Very thin flash modules for cameras are described that do not appear as a point source of light to the illuminated subject. Therefore, the flash is less objectionable to the subject. In one embodiment, the light emitting surface area is about 5 mm×10 mm. Low profile, side-emitting LEDs optically coupled to solid light guides enable the flash module to be thinner than 2 mm. The flash module may also be continuously energized for video recording. The module is particularly useful for cell phone cameras and other thin cameras.

摘要： In an LCD, a backlight having red, green, and blue LEDs is controlled to generate monochromatic light (e,g., blue) during a portion of a cycle, such as an image frame cycle. During another portion of the cycle, all the LEDs are illuminated to create white light. The color filter in the LCD panel contains, for each white pixel, a first color (e.g., red) subpixel filter, a second color (e.g., green) subpixel filter, and a clear subpixel area for passing white light and the monochromatic. The liquid crystal layer shutters are controlled to pass from 0-100% of the light for their associated subpixels to create a color image. With proper control of the shutters, any desired color of each white pixel can be achieved during the cycle. By converting one color filter to a clear area, the transmission efficiency of the display is greatly increased.
摘要翻译：在LCD中，控制具有红色，绿色和蓝色LED的背光，以在诸如图像帧周期的周期的一部分期间产生单色光（例如蓝色）。在循环的另一部分期间，所有的LED都被照亮以产生白光。 LCD面板中的滤色器对于每个白色像素包含第一颜色（例如，红色）子像素滤色器，第二颜色（例如，绿色）子像素滤色器和用于通过白光和单色的透明子像素区域。控制液晶层百叶窗从相关子像素的0-100％的光通过，以产生彩色图像。通过对百叶窗的适当控制，可以在该周期期间实现每个白色像素的任何期望的颜色。通过将一个滤色器转换为透明区域，显示器的传输效率大大提高。

摘要： A white light LED for use in backlighting or otherwise illuminating an LCD is described where the white light LED comprises a blue LED over which is affixed a preformed red phosphor platelet and a preformed green phosphor platelet. In one embodiment, to form a platelet, a controlled amount of phosphor powder is placed in a mold and heated under pressure to sinter the grains together. The platelet can be made very smooth on all surfaces. A UV LED may also be used in conjunction with red, green, and blue phosphor plates. The LED dies vary in color and brightness and are binned in accordance with their light output characteristics. Phosphor plates with different characteristics are matched to the binned LEDs to create white light LEDs with a consistent white point for use in backlights for liquid crystal displays.

摘要： Low profile, side-emitting LEDs are described that generate white light, where all light is emitted within a relatively narrow angle generally parallel to the surface of the light-generating active layer. The LEDs enable the creation of very thin backlights for backlighting an LCD. In one embodiment, the LED emits blue light and is a flip chip with the n and p electrodes on the same side of the LED. Separately from the LED, a transparent wafer has deposited on it a red and green phosphor layer. The phosphor color temperature emission is tested, and the color temperatures vs. positions along the wafer are mapped. A reflector is formed over the transparent wafer. The transparent wafer is singulated, and the phosphor/window dice are matched with the blue LEDs to achieve a target white light color temperature. The phosphor/window is then affixed to the LED.

摘要： High power white light LEDs are distributed within a thin reflective cavity. The cavity depth may be less than 3 cm and, in one embodiment, is about 1 cm. A light output surface of the cavity is a flat reflector with many small openings. A small plastic lens is positioned over each opening for causing the light emitted from each opening to form a cone of light between approximately 50-75 degrees. Alternatively, each hole may be shaped to be a truncated cone to control the dispersion. The light emitted by the LEDs is mixed in the cavity by reflecting off all six reflective walls of the cavity. The light will ultimately escape through the many holes, forming a relatively uniform pattern of light on a surface to be illuminated by the luminaire.

摘要： Amber light LEDs have a higher luminance than red light LEDs. A vast majority of images displayed on television consists of colors that can be created using amber, green and blue components, with only a small percentage of red. In one embodiment of the present invention, the typically red primary light source in a projection display system is augmented with an amber light source. Green and blue primary light sources are also provided. All the light sources are high power LEDs. The particular mixture of the red and amber light is accomplished by varying the duty cycles of the red LEDs and the amber LEDs. If the RGB image to be displayed can be created using a higher percentage of amber light and a lower percentage of red light, the duty cycle of the amber LEDs is increased while the duty cycle of the red LEDs is decreased. Light/pixel modulators for creating the full color image from the three primary light sources are controlled to compensate for the variable amber/red mixture. This technique improves the efficiency of the projection system and generates less heat. A further increase in luminance can be achieved by controlling the light mixture from green and cyan LEDs as a primary light source and/or by controlling the light mixture from blue and blue-cyan LEDs as a primary light source.
摘要翻译：琥珀色LED具有比红色LED更高的亮度。电视上显示的绝大多数图像包括可以使用琥珀色，绿色和蓝色组件创建的颜色，只有少量的红色。在本发明的一个实施例中，投影显示系统中的典型的红色一次光源用琥珀色光源增强。还提供绿色和蓝色的初级光源。所有的光源都是大功率LED。通过改变红色LED和琥珀色LED的占空比来实现红色和琥珀色光的特定混合。如果可以使用更高百分比的琥珀色光和较低百分比的红光来创建要显示的RGB图像，则红色LED的占空比减小时，琥珀色LED的占空比将增加。用于从三个主要光源产生全色图像的光/像素调制器被控制以补偿可变的琥珀色/红色混合物。这种技术提高了投影系统的效率并产生较少的热量。通过控制来自绿色和青色LED的光混合物作为主要光源和/或通过控制来自蓝色和蓝色 - 青色LED的光混合物作为主要光源，可以进一步提高亮度。
