  • Patent number: 10317062
    Abstract: An end cap for a solid-state lighting device is described that provides an electrical connection(s) between an external power source and at least one solid-state emitter disposed in a hollow member of the lighting device. An outer wall extends a first distance and an inner wall extends a second distance from an inward-facing side of the end cap base. A gap between the inner wall and the outer wall accommodates the insertion of the hollow member. A contactor electrically coupled to a conductive member on an opposite side of the end cap extends into the gap. The contactor exerts a force on a flexible conductor and provides a power supply path to or power return path from the at least one solid-state emitter. Preferably, the lighting device includes an array of solid-state emitters disposed on a flexible substrate.

  • Patent number: 10203443
    Abstract: A light emitting device includes a light guide plate and a light source. The light guide plate has a first surface, a second surface that is opposite to the first surface, at least one third surface, and a light incident surface. The third surface and the light incident surface are between the first and second surfaces. The third surface is adjacent to the light incident surface and has a concave-convex structure. The light source is located on the light incident surface. When the light source emits light, the light of the light source enters the light guide plate and transmits to the concave-convex structure, such that the light irradiates out from the concave-convex structure due to refraction, and is reflected back to the light guide plate by the concave-convex structure.
