摘要： An LED array includes three or more strings of bare LEDs mounted in close proximity to each other on a substrate. The strings of LEDs emit light of one or more wavelengths of blue, indigo and/or violet light, with peak wavelengths that are less than 490 nm. Luminescent materials deposited on each of the LED chips in the array emit light of different wavelength ranges that are of longer wavelengths than and in response to light emissions from the LED chips. A control circuit applies currents to the strings of LEDs, causing the LEDs in the strings to emit light, which causes the luminescent materials to emit light. A user interface enables users to control the currents applied by the control circuit to the strings of LEDs to achieve a Correlated Color Temperature (CCT) value and hue that are desired by users, with CIE chromaticity coordinates that lie on, or near to the black body radiation curve. Preferably a transparent material is dispensed on the substrate between the LED semiconductor chips to substantially surround the LED semiconductor chips. Thereafter at least one layer containing luminescent materials is applied on the LED semiconductor chips and the transparent material.
摘要翻译： LED阵列包括在基板上彼此靠近安装的三个或更多个裸露的LED串。 LED串发射蓝色，靛蓝色和/或紫色光的一种或多种波长的光，峰值波长小于490nm。 沉积在阵列中的每个LED芯片上的发光材料发射不同波长范围的光，其具有比来自LED芯片的光发射更长的波长。 控制电路向LED串施加电流，使得串中的LED发光，这导致发光材料发光。 用户界面使用户能够控制由控制电路施加到LED串的电流，以实现用户期望的相关色温（CCT）值和色相，其中CIE色度坐标位于黑色或接近黑色 身体辐射曲线。 优选地，透明材料被分配在LED半导体芯片之间的基板上，以基本上围绕LED半导体芯片。 此后，在LED半导体芯片和透明材料上施加至少一层含有发光材料的层。

摘要： A tunable wavelength filtering device is presented in which the tuning mechanism is based on altering the incident angle to an optical thin film coating stack, or thin film optical filter. Rotating mirrors, such as Micro-Electro-Mechanical Systems (MEMS) tilt-mirrors, are used to alter the incident angle of the optical beam coming from an input fiber, and also to aim or align the exiting beam to an output optical fiber. The optical thin film coating stack can be implemented onto a glass substrate, to form a thin film filter chip. The thin film filter chip can be fixed in place, and the incident angle and exiting angle of the optical beam is varied by adjusting the tilt angle of the two rotating mirrors.
