Abstract: A retrofit-style lamp is disclosed. The retrofit-style lamp includes a plurality of light sources, and a one-dimensional linear batwing lens. The one-dimensional linear batwing lens beam shapes light emitted by at least two light sources of the plurality of light sources. The retrofit-style lamp also includes a housing including the plurality of light sources, and attached to the one-dimensional linear batwing lens. The combination of housing and lens is then itself fitted with endcaps, including electrical connectors, for placement within a fixture, such as within an existing conventional fluorescent tube fixture located within a storage structure, for example a refrigeration case. Alternatively, the plurality of light sources, the one-dimensional linear batwing lens, and the housing may be formed, along with a power supply, as a standalone retrofit fixture for use in enclosed storage structures, such as refrigeration cases, where the retrofit fixture replaces a conventional fluorescent fixture.

Abstract: An edge-lit light panel is disclosed, which includes a generally planar, transparent light guide. Light, such as from one or more solid state light source arrays, is coupled into the light guide through its lateral edge, and propagates generally laterally within the light guide via total internal reflection. A diffuser is attached to the front or rear face of the light guide, such as by lamination. The diffuser may have a refractive index matched to that of the light guide. The light guide may have one or more concave features on its lateral edge to reduce reflection losses at high angles of incidence. The concave features may include a single, one-dimensional groove that includes all the solid state light sources along a particular straight edge of the light panel, or may include a series of concave dimples, with one dimple for each solid state light source.

Abstract translation: 公开了一种边缘照明的光板，其包括大致平面的透明光导。 诸如来自一个或多个固态光源阵列的光通过其侧边缘耦合到光导中，并且通过全内反射在光导内通常横向地传播。 扩散器例如通过层压连接到光导的前表面或后表面。 扩散器可以具有与光导的折射率匹配的折射率。 导光体可以在其侧边缘上具有一个或多个凹形特征，以减小高入射角的反射损失。 凹形特征可以包括单一的一维凹槽，其包括沿着光板的特定直边缘的所有固态光源，或者可以包括一系列凹陷凹坑，每个固态光源具有一个凹坑。
