摘要： This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light. In one aspect, the light guide has a light input edge into which light is injected and transverse edges transverse to the light input edge. The transverse edges are smooth and act as specular reflectors. The light input edge is rough and provides a diffusive interface. The light emitters are adjacent and centered along the light input edge, with the pitch of the light emitters being about ?L, where ?L is the distance between the transverse edges divided by the number of light emitters. The diffusive light input edge can diffuse light entering into the light guide, and the transverse edges can reflect light with a low level of artifacts and the reflections also act as virtual light sources to facilitate a highly uniform distribution of light within the light guide. The light guide can be provided with light turning features that redirect light out of the light guide. In some implementations, the redirected light can be applied to illuminate a display.
摘要翻译：本公开提供了通过使用光导来分配光来提供照明的系统，方法和装置。在一个方面，光导具有光输入边缘，光注入到该光输入边缘中，横向边缘横向于光输入边缘。横向边缘是光滑的并且用作镜面反射器。光输入边缘粗糙并提供扩散界面。光发射器相邻并沿着光输入边缘居中，发光体的间距约为λL，其中λL是横向边缘之间的距离除以发光体的数量。扩散光输入边缘可以漫射进入光导的光，并且横向边缘可以以低水平的伪像反射光，并且反射也用作虚拟光源，以促进光在光导内的高度均匀分布。光导可以设置有将光从光导引导出的光转向特征。在一些实施方案中，可以应用重定向的光来照亮显示器。

摘要： This disclosure provides systems, methods and apparatus for providing illumination by using a light guide (120) to distribute light. In one aspect, a passivation layer (110) is attached to the light guide of an illumination device. The passivation layer may be an optically transparent moisture barrier and may have a thickness and refractive index which allows it to function as an anti - reflective coating. The passivation layer may protect moisture - sensitive underlying features, such as metallized light turning features (140) that may be present in the light guide. The light turning features may be configured to redirect light out of the light guide. In some implementations, the redirected light may be applied to illuminate a display.

摘要： Various embodiments of the present invention relate to enhancing the brightness of displays that employ illumination systems. In some embodiments, the illumination systems include light guides (915), diffractive microstructure (910), and light-turning features (905). The diffractive microstructure may be configured to receive ambient light at a first angle and produce diffracted light at a second angle greater than the first angle and greater than the critical angle of the light guide. The light is thereby guided within the light guide. The light-turning features may be configured to turn the light guided within the light guide out of a light guide and onto, for example, the pixels (901) of a spatial light modulator at near normal incidence.
