A light mixing chamber includes a housing having a channel formed therein, with the channel exposed to an exterior of the housing. A chamber is formed in the housing, and an aperture formed in the housing connects the chamber to the channel. The chamber may house an LED, with an optical member being retained within the channel. A light guide plate may be positioned on an exterior of the housing outside the channel.

Light mixing chamber for use with light guide plate

An illumination device including a light source positioned at the distal end of a reflecting unit and a heat sink light transmissive substrate including quantum dots positioned at the proximal end of the reflecting unit with the reflecting unit having one or more reflecting side walls and a reflecting bottom wall and with the light source being separated a distance from the light transmissive substrate including quantum dots. In certain embodiments, the light source is an LED.

Quantum dot containing optical element

A solid state lighting device including a light source capable of emitting white light including a blue spectral component and having a deficiency in a spectral region, and an optical component that is positioned to receive at least a portion of the light generated by the light source, the optical component comprising an optical material for converting at least a portion of the blue spectral component of the light to one or more predetermined wavelengths such that light emitted by the solid state lighting device includes light emission from the light source supplemented with light emission at one or more predetermined wavelengths, wherein the optical material comprises quantum confined semiconductor nanoparticles. Also disclosed is lighting fixture, a cover plate for a lighting fixture and a method.

Solid state lighting devices including quantum confined semiconductor nanoparticles, an optical component for a solid state lighting device, and methods

A glass tube including quantum dots in a polymerized matrix is described. An optical component and other products including such glass tube, a composition including quantum dots, and methods are also disclosed.

Stress-resistant component for use with quantum dots

A light mixing chamber of a backlight includes a housing having a channel and a chamber exposed to the channel, an LED positioned within the chamber, and a capillary containing quantum dots positioned in the channel. A light guide plate is positioned adjacent the housing and adjacent the capillary. Relative dimensions of the elements of the light mixing chamber, as well as features added to the elements of the light mixing chamber, can be varied to balance efficiency and uniformity of light generated in the backlight.
