    Abstract: A direct-view lighting arrangement (24) suitable for the backlight of a liquid crystal display (LCD) (22) , comprising (in that order) an array of surface-emitting light sources (LEDs) (14) with an angular luminous intensity distribution, an array of beam spreading optical elements (28) , an array of Fresnel lenses (32) to reduce beam divergence and an (optional) diffuser (38) . The refractive properties (convex and concave) of the beam spreading optical elements make the luminous flux essentially constant at the illumination plane (where the LCD is located). Thus, the beam spreading optical elements refract more light into higher beam angles thus compensating for the corresponding fall-off in luminous intensity of the sources. The thin sheet of Fresnel lenses reduces the divergence of the beams and directs them on to the diffuser. The (weak) diffuser serves to add a further beam divergence suitable for various applications, rather than itself producing uniformity in the illumination. The arrangement allows for a slimmer backlight design, eliminating the need for a strong diffuser having a high haze value (>90%). Keywords: Lambertian source,- illuminance, -luminance.

    Abstract translation: 一种适用于液晶显示器（LCD）（22）的背光源的直视照明装置（24），包括（依次）具有角度发光强度的表面发射光源（LED）阵列（14） 光束扩散光学元件阵列（28），减少光束发散的菲涅尔透镜阵列（32）和（可选）扩散器（38）。 光束扩散光学元件的折射特性（凸和凹）使光束在照明平面（LCD所处的位置）基本恒定。 因此，光束扩展光学元件将更多的光折射成更高的光束角度，从而补偿源的发光强度的相应的脱落。 菲涅尔透镜的薄片减少了光束的发散，并将它们引导到扩散器上。 （弱）扩散器用于增加适用于各种应用的另外的光束发散，而不是本身在照明中产生均匀性。 该布置允许更薄的背光设计，消除了对具有高雾度值（> 90％）的强扩散器的需要。 关键词：朗伯源， - 照度，亮度。

    Abstract: A lamp including a two-sided source plate, a plurality of light sources, a lens, a diffuser plate, and a driver insulator is disclosed. One set of the light sources generates white light and is attached to one side of the source plate. Another set of the light sources generates colored light and is attached to the source plate's other side. The lens encapsulates the white light-generating set, and redirects that white light. The driver insulator and the diffuser plate are each in contact with the source plate's other side. The driver insulator, diffuser plate, and that side of the source plate define a light box region that contains the colored light-generating set of light sources. The driver insulator acts as a reflector, and the diffuser plate acts as a diffuser, such that colored light is dispersed from the light box region through the diffuser plate.

    Abstract: A lamp having a candle-like appearance and using one or more light-emitting diodes (LEDs) as its light source. Light is emitted from only a small volume at or near the bulb's center. Heat sink and control electronics are outside the bulb. Inside the bulb, a set of secondary optics guides light to an emission point at a prescribed location in the bulb's interior. The secondary optics include a light pipe that guides light away from an LED chip, and a volume scattering element, made from a transparent base material and including transparent particles of a predetermined size and refractive index, that receives light from the light pipe, scattering it. The density of particles in the volume scattering element, the particle size, and the particle refractive index are chosen to produce a scattering pattern that directs more light toward the bulb's base, while maintaining reasonable efficiency.
