This invention provides low voltage lighting assemblies and lighting systems that are easy to install, and are particularly useful in landscape lighting applications. Electrical connections between all components, including lighting assemblies, switches, power supplies, etc., are simplified through use of connectors. In one embodiment a lighting assembly comprises a circuit card having first and second zones, and a spanning zone that separates the first zone from the second zone by a selected distance. The electrical connectors and other elements are disposed in the first zone, and at least one lighting element such as an LED is disposed in the second zone. Installation of the embodiments requires little or no modification of the structures in which they are installed, since the spanning zone is adapted to span across the structure. The electrical connectors and other elements in the first zone are concealed by the structure, and substantially only the compact, low-profile second zone with the LED is exposed, producing a highly aesthetic result.

A light-emitting module that includes a light source and an optical lens is provided. The light source emits an original beam along a direction of a light-emitting axis, and the optical lens is disposed on a transmission path of the original beam. The original beam passes the optical lens and becomes an illumination beam. A light shape of the illumination beam has a first full width at half maximum (FWHM) along a first direction and has a second FWHM along a second direction, and a ratio of the second FWHM to the first FWHM is large than 3. The first direction and the second direction are perpendicular to the direction of the light-emitting axis. A light-emitting device is also provided.
