Abstract: Light assemblies comprise a housing having a chamber, one or more light emitting elements connected with the housing, a transparent cover, and one or more reflectors positioned adjacent the light emitting element. The one or more light emitting elements are interposed between the transparent cover and the one or more reflectors, and the one or more light emitting elements and one or more reflectors operate to provide a multi-directional field of illumination that is 180 degrees or more, e.g., between about 180 to 270 degrees. The transparent cover may have a convex outer surface to facilitate light transmission in side oriented directions. The light assembly may include switches or controls for on/off and/or dimming functions. An example light assembly comprises three light emitting elements in the form of LEDs, and includes three reflectors, wherein the LEDs and reflectors are configured to produce the desired field of illumination.

Abstract: A wavelength conversion element includes a support member having a supporting surface, and a wavelength converter disposed above the supporting surface. The wavelength converter contains first fluorescent particles which absorb excitation light and generate fluorescence (second radiation light), and a transparent binder which bonds the first fluorescent particles, and has a joint surface facing supporting surface, and an incident surface disposed opposite to the joint surface, the excitation light entering the incident surface. The excitation light and fluorescence are emitted from the incident surface. The wavelength converter includes projections. At least part of the projections is disposed on the incident surface. The first fluorescent particles are partially exposed from vertices of the projections.
