    Abstract: An optical lens assembly includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eighth lens. The first lens has a convex surface toward an object side of the optical lens assembly and a concave surface toward an imaging side of the optical lens assembly. The first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the seventh lens and the eighth lens are sequentially arranged along an optical axis from the object side to the imaging side.

    Abstract: A light emitting device is provided to produce white light with a stable correlated color temperature and stable color coordinates. The light emitting device includes a blue LED chip and a yellow phosphor. The blue LED chip has a peak wavelength X slightly smaller than the peak wavelength Y of the phosphor such that when the light emitting device is subjected to a predetermined operating current, the phosphor decays due to thermal effect, and the LED chip has its emission spectrum red-shifted to substantially match with the excitation spectrum of the phosphor. At this time, the excitation ability of the LED chip is increased and causes an increase of yellow power output from the phosphor that substantially compensates a decrease of yellow light output caused by the phosphor.

    Abstract translation: 提供发光器件以产生具有稳定的相关色温和稳定色坐标的白光。 发光器件包括蓝色LED芯片和黄色荧光体。 蓝色LED芯片的峰值波长X比荧光体的峰值波长Y稍小，因此当发光元件经受规定的工作电流时，荧光体由于热效应而衰变，LED芯片的发光光谱 红移以与荧光体的激发光谱基本匹配。 此时，LED芯片的激发能力增加，并且导致从荧光体输出的黄色功率的增加，其基本上补偿由磷光体引起的黄光输出的减少。

    Abstract: A diffractive optical assembly includes an input coupler, an output coupler, and an image source. The output coupler is next to the input coupler. One of the input coupler and the output coupler has a most critical holographic optical element (HOE), and another one has a diffractive optical element (DOE). Bragg condition of the most critical HOE is more sensitive than Bragg condition of the DOE. The image source is configured to generate image light that is incident to the input coupler then propagates to the output coupler. The image light has incident angles to the input coupler and wavelengths corresponding to the incident angles. The wavelengths of the image light on the image source have a two-dimensional spatial distribution, such that relationships between the incident angles and the wavelengths of the image light comply with Bragg selectivity of the most critical HOE.

    Abstract: A lamp structure of an adaptive streetlight includes a housing, a plurality of light sources, and a surface-structured diffusion plate. The surface-structured diffusion plate enables the lamp structure to provide a light pattern conforming to the curvature of the road to be illuminated or other sites of application, thus reducing not only the number of lamps or streetlights required for a curvy road section, but also the associated installation cost and power consumption. The lamp structure can enhance road users' safety and the safety of our daily lives by increasing the illuminance on a curvy road and other sites of application that have special requirements.

    Abstract: A holographic device includes a holographic storage device, a shearing interferometer, and an optical receiver. The holographic storage device is configured to provide a disk with a reading light beam to make the reading light beam become a diffracted light beam after the reading light beam is diffracted in the disk. The shearing interferometer is configured to receive the diffracted light beam and to transform the diffracted light beam into a first light beam and a second light beam. The optical receiver is configured to receive the first light beam and the second light beam provided by the shearing interferometer.
