Abstract
The efficiency of one or more LED installations is achieved by holding the junction temperature of an LED at a low level by soldering the LED die to a small threaded metallic piece, such as a nut, which is then clamped to a larger piece having a lower thermal resistance to the air or other heat conducting medium surrounding the combination. Each of the die-nut subassemblies can be fastened to the larger metallic piece closely together without endangering any previously fastened die-nut subassemblies, thus achieving denser groups of installed LEDs. Assemblies according to this invention can operate efficiently in an electrical system several thousand meters long.
Claims8
A light emitting diode assembly comprising
- a light emitting diode,
- a plate member configured for rapid dispersal of heat generated by the diode into a medium surrounding the plate, and
- an intermediate member forming a junction between the diode and the plate member configured to transmit heat generated by the diode to the plate member and to maintain the temperature at the junction below an equilibrium of heat from the diode and heat disbursed by the plate member.
A light emitting diode assembly comprising
- a plurality of light emitting diodes,
- a plate member having a configuration for rapid dispersal of heat generated by the diodes into a medium surrounding the plate member, and
- an intermediate member for each diode forming a junction between the diode and the plate member and configured to transmit heat from the diode to the plate member and maintain the temperature at the junction below an equilibrium of heat from the diode and heat dispersed by the plate member.
