摘要： A light emitting diode module is produced using at least one light emitting diode (LED) and at least two selectable components that form or are part of a light mixing chamber that surrounds the LEDs and includes an output port. A first selectable component has a first type of wavelength converting material with a first wavelength converting characteristic and a second selectable component has a second type of wavelength converting material with a different wavelength converting characteristic. The first and second wavelength converting characteristics alter the spectral power distribution of the light produced by the LED to produce light through the output port that has a color point that is a predetermined tolerance from a predetermined color point. Moreover, a set of LED modules may be produced such that each LED module has the same color point within a predetermined tolerance. The LED module may be produced by pre-measuring the wavelength converting characteristics of the different components selecting components with wavelength converting characteristics that convert the spectral power distribution of the LED to a color point that is a predetermined tolerance from a predetermined color point.

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.
摘要翻译：单独的侧发光LED分别定位在波导中，或者一起安装在柔性安装件上，然后将其定位在波导中。结果，每个LED和波导之间的间隙可以很小，这可以改善来自LED到光波导的光的耦合。由于LED分别连接到波导或安装在柔性安装座上，因此减小了由波导形状的变化引起的对各个LED的应力。

摘要： One or more LEDs are mounted within an LCD without the use of any printed circuit board (PCB), thus reducing the thickness of the LCD by about the thickness of the conventional PCB. In one embodiment, the LED and submount are mounted so that the submount is opposing the liquid crystal layer side of the LCD, so that the liquid crystal layers provide the mechanical support for the submount and LED die. The LED die (mounted on the submount) may be inserted into a cavity formed in the “top” surface of the light guide, and the top surface of the light guide is abutted against the liquid crystal layers. In such a configuration, the LED light source, including all supporting components, adds no thickness to the LCD. In another embodiment, on the “bottom” surface of the LCD opposing the LED die is an electrically switchable mirror that is either reflective or transparent. In its transparent state, the LED in the LCD may be used as a flash in a cell phone camera, while the LCD may be viewed to take the picture.

摘要： A light emitting device is produced using one or more light emitting diodes within a light mixing cavity formed by surrounding sidewalls. The light emitting device includes a light adjustment member that is movable to alter the shape or color of the light produced by the light emitting device. For example, the light adjustment member may alter the exposure of the wavelength converting area to the light emitted that is emitted by the light emitting diode in the light mixing cavity. Alternatively, the height of a lens may be adjusted to change the width of the beam produced. Alternatively, a movable substrate with areas of different wavelength converting materials may adjustably cover the output port of the light mixing cavity to alter the color point of the light produced.

摘要： A system for purifying a fluid uses ultra violet (UV) light to inactivate micro-organisms present in the fluid. The system has an arrangement of UV light emitters on perforated plates. The fluid, while passing through perforations in the perforated plates, is exposed to the UV light emitted by the UV light emitters. Micro-organisms present in the fluid pass very close to the UV light emitters. The UV light absorbed by the micro-organisms causes genetic damage and inactivation. The system has feedback units providing feedback about the physical properties of the fluid to a power unit supplying power to the UV light emitters. The power unit varies the amount of power supplied to the UV light emitters, based on the feedback.

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： An illumination source includes at least one light emitting diode, e.g., in array of LEDs that produce short wavelength light. One or more wavelength converting elements, such as phosphor elements, convert at least a portion of the short wavelength light from the LED(s) to longer wavelengths, such as Red and Green. A dichroic element positioned between the LED(s) and the wavelength converting element(s) transmits the light from the LED(s) and reflects the longer wavelengths from the wavelength converting element(s). A color selection panel selects the colors of light to be produced by the illumination device and to be recycled for another opportunity to be converted by the wavelength converting element(s) or to be reflected by the dichroic element. The color selection panel may operate in one or both of the spatial domain and the temporal domain.

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。
