Abstract: Disclosed lens designs enable uniform light distribution without hot spot, achieving wider transfer functions of light compared with traditional lenses, with a benefit of reducing the number of light sources needed and overall cost for direct-lit backlight device. A disclosed lens includes a beam shaping element on the top thereof and a backlight device incorporating the lens and the beam shaping element to eliminate a light hot spot produced by the backlight device and obtain a uniform light distribution at the illumination field. The disclosed lens is especially useful when extremely wider transfer function or extremely thin backlight is needed.

Abstract: A light fixture has two reflective blades that are adjustable. Adjusting the setting on the reflective blades allows for the controlling of how widely or narrowly the light will be focused from the light fixture. The reflective blades reside within the light fixture, and are positioned on either side of the lamp. The reflective blades attach to the light fixture via a fastener on two ends of the light fixture's casing, while alloblade each reflective blade to pivot along the two fasteners. The reflective blades are pivoted along the fasteners, and are held stationary through the use of a spring loaded knob that has a rounded base for embedding itself with in receptacle on the light fixture's casing.

Abstract: Disclosed is a luminaire such as an LED downlight which is suitable for mounting in ceiling cavities of commercial environments. An example luminaire (200) comprises a light source (202) including an integral primary optic which is configured to transmit light toward a second optic (214). The second optic (214) is a lens configured to receive light from the light source (202) via the primary optic and transmit at least part of the received light toward a circular reflector (201). The circular reflector (201) is configured to direct light received from the second optic (214) away from the luminaire (204). A shape of the second optic (214) is interdependent with a shape of the circular reflector (201), and the shape of the second optic (214) and circular reflector (201) act in combination to transmit light away from the luminaire with a non-circular illuminance distribution (206).

Abstract: A retainer ring for a light fixture includes a cylindrical main body section that defines a cylindrical axis, and an inner retaining flange that extends radially inward from a distal end of the main body section. The inner retaining flange extends substantially about a circumference of the distal end. One or more coupling features extend radially inward from the retainer ring. A customization kit for a light engine that defines an optical axis includes a retainer ring configured to couple with the light engine, and two or more primary optics that are mechanically compatible with the light engine, and retainable to the light engine with the retainer ring. When the retainer ring couples with the light engine, a cylindrical axis of the retainer ring coincides with the optical axis.

Abstract: A lampholder and a luminaire are provided. The lampholder includes a recess, a base of which has a luminous unit installing side; and a reflecting flank, extending from the recess and having a reflecting face facing the luminous unit installing side. The luminaire includes the lampholder. With the lampholder and the luminaire, conventionally discrete lampholder and light reflecting shade are made into an integral lampholder, so that structure is more simple, and the connecting step of a light emitting shade and a lampholder is cut down. In addition, the recess configuration of the lampholder is usable for accommodating an externally arranged power supply of a luminous unit, thereby saving the storage space, and reducing the warehousing and logistics costs.
