  • Patent number: 8905566
    Abstract: A flat-panel display (such as a liquid crystal display) includes one or more features that reduce temperature changes in an array of light valves disposed on a substrate. In particular, heat generated in a light source and/or electronics is conducted away from the light values. For example, a light-source holder, which contains the light source, may include holes that increase the thermal resistance between the light source and the substrate. Alternatively, the light-source holder may include a material having a thermal conductivity that is higher than that of stainless steel. In addition, the flat-panel display may include materials and/or a geometry that increases the thermal resistance along a direction in a plane of the substrate. By reducing temperature changes in the flat-panel display, these features can reduce or eliminate color changes and other visual artifacts that can degrade the quality of displayed images.

A deflector is secured to the housing and is positioned to extend over some portion of the heat exit. The deflector guides heat away from the housing in a direction. In some configurations, the deflector guides heat away from the housing in a direction that is opposite the direction in which the array of light-emitting elements emit light. Also, some lighting modules have multiple heat exits and may have multiple deflectors extending over a portion of the respective heat exits.

  • Patent number: 8882301
    Abstract: A method for bonding an LED assembly (71) or other electronic package (31) to a substrate PCB containing a heat-sink (52), which utilizes layers of reactive multilayer foil (51) disposed between contacts (32, 34) of the electronic package 31 and the associated contact pads (55) on the supporting substrate PCB. By initiating an exothermic reaction in the reactive multilayer foil (51), together with an application of pressure, sufficient heat is generated between the contacts (32, 34) and the associated contact pads (55) to melt adjacent bonding material (54) to obtain good electrically and thermally conductive bonds between the contacts 32, 34 and contact pads (55) without thermally damaging the electronic package (31), heat-sensitive components (35) associated with the electronic package (31), or other the supporting substrate PCB.

  • Patent number: 8875373
    Abstract: A manufacturing method of heat conductive device for an LED has steps of forming a heat sink and an engagement recess in the heat sink by cold forge, punching a heat-conducting disc to form an LED carrier having a mounting portion and a heat-conducting wall formed around the mounting portion, soldering multiple LEDs on the LED carrier, and heating the heat sink to thermally expand the heat sink and assembling the LED carrier and the heat sink so that the heat-conducting wall is assembled with the engagement recess and further chilling the heat sink to thermally retract and tightly hold the LED carrier. The manufacturing method increases contact area and reduces air gaps between the LED carrier and the heat sink to effectively enhance the heat-conducting efficiency of the LED carrier so that the LEDs are operated at a suitable operating temperature to secure a prolonged life duration.

  • Patent number: 8870417
    Abstract: A modular lighting fixture assembly. Multiple light pods can be removably mounted on both lateral sides of a mechanical thermal element, such as an elongated heat sink. The pods can be easily removed for cleaning, maintenance, and transport, for example. A light strip including multiple LEDs can be mounted to a surface of the heat sink on both sides. Each pod has a portion cutaway such that when the pods are mounted to the heat sink, the cutaway portions align with the light strips. Thus, when mounted, the light strip can be adjacent to or protrude into an interior cavity of the pod. The interior surfaces of the pods are shaped to redirect light in a particular output profile. The assembly may be mounted to a ceiling and used as an overhead fixture designed to efficiently light an aisle in a retail space or a storage facility, for example.
