A package LED may include a housing positioned on a supporting submount, sized and dimensioned to accommodate a single LED chip or an array of LED chips. The LED chip(s) may be attached to the submount utilizing the Gold-to-Gold Interconnect (GGI) process or solder-based approaches. In some embodiments, phosphor may be deposited on top of the LED chip(s) or sandwiched between glass plates on top of the LED chip(s). The phosphor layer may be inside or on top of the housing and be secured to the housing utilizing an adhesive. The housing may be adhered to the submount utilizing a thermal epoxy. | 06-17-2010 |
20100066941 | HYBRID LIGHTING PANEL AND LCD SYSTEM - A hybrid lighting panel may have a first light guide and a second light guide proximate to the first light guide. The first light guide may receive light from a light source such as an LED array. The first light guide is configured to distribute the light along the length of the first light guide and distribute the light out a first light guide face such that light exiting the first light guide face enters the second light guide. The second light guide is configured to distribute light across the width of the second light guide and distribute light out a second light guide face. Hybrid lighting panels may be used individually or assembled as a system to provide light. A controller can control lighting to each panel to allow for individual dimming.
