An emergency egress light fixture is disclosed herein. The emergency egress light fixture can include a first light chamber base forming a first light chamber, where the first light chamber base includes at least one first reflector insert coupling feature. The emergency egress light fixture can also include at least one first light source disposed in the first light chamber. The emergency egress light fixture can further include a first reflector insert disposed within the at least one first reflector insert coupling feature, where the first reflector insert divides the first light chamber into a first portion and a second portion, where the at least one first light source is disposed in the first portion, and where the second portion is substantially dark when the at least one first light source is illuminated.

A light fixture includes a circuit board having a plurality of light-emitting elements, and a plurality of collimators positioned adjacent the circuit board. Each of the collimators includes a first end positioned adjacent one of the light-emitting elements, a second end, and an interior wall extending between the first end and the second end. The wall is curved to internally reflect the light output of the associated light-emitting element and focus the light through the second end and provide a light distribution. The light fixture further includes a beam controlling optic positioned adjacent the second end of the plurality of collimators to modify the light output from the plurality of collimators to provide a modified light distribution.

A lamp, comprising at least one light source (3), arranged in a housing (1) having at least one light exit opening, and at least one reflector (4), which is shaped in such a way that the light coming from the light source (3) is divided into at least two light beams, the light exit opening being at least partially covered by a cover panel (5), which has two surface portions (5a, 5b) on which the respectively corresponding light beams impinge, the surface portions (5a, 5b) being shaped in such a way that the predominant part of the light beams that is respectively directed onto a surface portion (5a, 5b) impinges on the surface portion (5a, 5b) at an angle of incidence which is less than 60°, in order to reduce the reflections from the cover panel (5).

In accordance with certain embodiments, systems of lighting components feature multiple illumination panels each having a backing support and, secured thereto, multiple illumination elements. The illumination elements have shapes defined by arrangements of illumination unit cells may be assembled to illuminate an arbitrary two-dimensional area.

A light emitting device includes a mounting board, light sources, a light diffuser, a wavelength conversion layer, and scatter reflection portions. Each of the light sources has an upper face on which a light reflecting layer is disposed. The light diffuser is arranged above the plurality of light sources. The wavelength conversion layer is located at least between the light sources and the light diffuser. The wavelength conversion layer is configured to absorb at least a portion of light from the light sources and to emit light having a wavelength which is different from a wavelength of the light from the light sources. The scatter reflection portions are arranged on a surface of the wavelength conversion layer that is closer to the light diffuser. Each of the scatter reflection portions is arranged above at least a portion of the upper face of a corresponding one of the light sources.

A rectangular wide-beam flashlight that utilizes a plurality of LEDs positioned in specifically formed optical elements to generate a uniform, rectangular beam pattern configured to substantially illuminate one or more walls in a room. The flashlight uses a radial array of LEDs that are disposed at or within optical elements or cavities configured to combine the output of the LEDs to form a substantially uniform and seamless, high-aspect ratio or wide rectangular beam for adequately illuminating one or more walls in a room.

A light emitting device includes: a mounting board; a plurality of light sources positioned on the mounting board; first and second prism array layers stacked with each other; a dichroic layer positioned between the first and second prism array layers and the plurality of light sources; and a wavelength conversion layer positioned between the first and second prism array layers and the dichroic layer.

An optical cup which mixes multiple channels of light to form a blended output, the device having discreet zones or channels including a plurality of reflective cavities each having a remote phosphor light converting appliance covering a cluster of LEDs providing a channel of light which is reflected upward. The predetermined blends of phosphors provide a predetermined range of illumination wavelengths in the output.

A light emitting device includes a base having a light reflecting surface and having a first side on which the light reflecting surface is provided, light sources mounted on the first side, and a half mirror disposed opposite to the base to reflect a part of incident light and to transmit another part of the incident light. Each of the light sources includes a reflecting layer on an upper surface of each of the light sources. The half mirror has an oblique reflectance with respect to wavelengths of light emitted from the light sources in a case where the light travels obliquely toward the half mirror. The half mirror has a perpendicular reflectance with respect to the wavelengths in a case where the light travels perpendicularly toward the half mirror. The oblique reflectance is smaller than the perpendicular reflectance.

A lighting apparatus comprising: a mounting substrate being arranged in the lighting apparatus at an angle below 45° with respect to a vertical direction; a plurality of light sources mounted on a lower or vertical surface of the mounting substrate such that at least two light sources are at a different height; a plurality of lens elements provided to the mounting substrate such that each of the light sources is provided with a corresponding lens element; at least two reflector elements provided to the at least two light sources, such that each of the at least two reflector elements has a reflective surface facing the mounting substrate; wherein each of the at least two reflector elements extends between a first edge, located above a corresponding light source as seen in a vertical direction, and a second edge, located below a corresponding light source as seen in a vertical direction.
