Patent number: 10205046Abstract: Contrary to conventional wisdom, which holds that light-emitting diodes (LEDs) should be cooled to increase efficiency, the LEDs disclosed herein are heated to increase efficiency. Heating an LED operating at low forward bias voltage (e.g., V<kBT/q) can be accomplished by injecting phonons generated by non-radiative recombination back into the LED's semiconductor lattice. This raises the temperature of the LED's active rejection, resulting in thermally assisted injection of holes and carriers into the LED's active region. This phonon recycling or thermo-electric pumping process can be promoted by heating the LED with an external source (e.g., exhaust gases or waste heat from other electrical components). It can also be achieved via internal heat generation, e.g., by thermally insulating the LED's diode structure to prevent (rather than promote) heat dissipation. In other words, trapping heat generated by the LED within the LED increases LED efficiency under certain bias conditions.Type: GrantFiled: June 26, 2017Date of Patent: February 12, 2019Assignee: Massachusetts Institute of TechnologyInventors: Parthiban Santhanam, Dodd Joseph Gray, Rajeev Jagga Ram

Patent number: 7492103Abstract: Disclosed is a multi-functional energy-saving fluorescent lamp in which an illumination sensor for distinguishing day and night, a timer for time control, and an infrared sensor for sensing a human are integrally provided to one lamp as a light source. The sensors measure illumination according to quantity of light or sense existence of a human. If the illumination around the lamp is lower than a certain level, e.g. at night, or a human exists, the sensors send a data signal for driving a lighting control circuit so that the lamp is automatically turned on/off. This lamp has simple structure and ensures low energy consumption. In addition, by addition of a reflection shade, heat emitted from the lamp is blocked and the illumination efficiency is improved. This lamp may be conveniently installed to any place using a socket-type light bulb without any separate sensor, thereby greatly improving convenience of a user.Type: GrantFiled: August 17, 2004Date of Patent: February 17, 2009Inventor: Yoon Kyu Hwang
