摘要： A light emitting device comprises a flip-chip light emitting diode (LED) die mounted on a submount. The top surface of the submount has a reflective layer. Over the LED die is molded a hemispherical first transparent layer. A low index of refraction layer is then provided over the first transparent layer to provide TIR of phosphor light. A hemispherical phosphor layer is then provided over the low index layer. A lens is then molded over the phosphor layer. The reflection achieved by the reflective submount layer, combined with the TIR at the interface of the high index phosphor layer and the underlying low index layer, greatly improves the efficiency of the lamp. Other material may be used. The low index layer may be an air gap or a molded layer. Instead of a low index layer, a distributed Bragg reflector may be sputtered over the first transparent layer.

摘要： A rounded square lens is used instead of a hemispherical lens in an LED package to produce a substantially Lambertian light emission pattern. A cross-sectional view of the rounded square lens cut along its diagonal forms a semicircular surface so as to emulate a hemispherical lens in areas close to the diagonal. A cross-sectional view of the lens cut along its width bisecting the lens forms a bullet shaped surface narrower than the semicircular surface but having the same height as the semicircular surface. The four corners of the lens are rounded. The surface of the lens smoothly transitions between the two surface shapes. Since the rounded square lens has a diagonal dimension larger than a maximum allowable diameter of a hemispherical lens in the same package body, a larger LED die may be used with the rounded square lens to output more light without increasing the size of the package while maintaining a Lambertian emission.

摘要翻译： 使用圆形方形透镜代替LED封装中的半球形透镜，以产生基本上朗伯的发光图案。 沿其对角线切割的圆形方形透镜的横截面图形成半圆形表面，以便在靠近对角线的区域中模拟半球形透镜。 沿其等距透镜的宽度切割的透镜的横截面视图形成比半圆形表面窄但具有与半圆形表面相同的高度的子弹形表面。 透镜的四个角是圆形的。 透镜的表面在两个表面形状之间平滑过渡。 由于圆形方形透镜的对角线尺寸大于同一封装体中的半球透镜的最大允许直径，因此可以使用较大的LED管芯与圆形方形透镜一起输出更多的光，而不会增加封装的尺寸，同时保持 朗伯式发射。

摘要： A substantially hemispherical lens surrounding an LED die is described that creates a sparkle as an observer views the lens from different angles. The lens is formed of an interconnected array of 100-10,000 or more lenslets. Each lenslet focuses an image of the LED die at an output of the lenslet such that the LED die image area at the output is less than 1/9 the area of the LED die to create a substantially point source image of the LED die at an outer surface of the lens. When the LED die is energized, the shape of each lenslet causes point source images of the LED die to be perceived by an observer at various viewing angles, such that the emitted LED light appears to sparkle and speckle as the observer moves relative to the lens.

摘要： A white light LED flash for a digital camera is described that uses a blue light LED die in conjunction with red and green phosphor or quantum dot material over the LED die. The phosphor or quantum dot characteristics are selected so that the white light substantially matches an ambient light setting in the camera, such as the incandescent ambient light setting. Therefore, when a flash picture is taken under incandescent ambient light, and the flash emits the same type of light as the incandescent light, the flash will effectively brighten the incandescent light. The camera's color compensation algorithm associated with incandescent light illumination is then applied to the photograph and works optimally since the image is only illuminated by incandescent light. This concept is expanded to LED flashes that emulate other types of ambient light having associated color compensation algorithms programmed into the camera.

摘要翻译： 描述了一种用于数字照相机的白光LED闪光灯，其使用蓝光LED管芯与LED芯片上的红色和绿色磷光体或量子点材料相结合。 选择荧光体或量子点特性，使得白光基本上与照相机中的环境光设置（例如白炽环境光设置）匹配。 因此，当在白炽环境光下拍摄闪光灯，并且闪光灯发出与白炽灯相同类型的光时，闪光灯将有效地使白炽灯变亮。 然后将照相机与白炽灯照明相关联的色彩补偿算法应用于照片，并且最佳地工作，因为图像仅被白炽灯照亮。 这个概念扩展到LED闪光灯，其模拟其他类型的环境光，其具有被编入相机的相关联的颜色补偿算法。

摘要： Images are captured within a camera. Upon preliminary image capturing being initiated, color balancing and auto-focus is performed and a predetermined number of images are captured for storage in a first-in-first-out buffer. This is repeated until capture is terminated. Upon a final image capture being initiated, a first image is transferred from the first-in-first-out buffer to a long-term memory within the camera.
