NEW CIRCUIT SOLUTIONS FOR THERMAL DESIGN OF CHANDELIERS WITH LIGHT EMITTING DIODES

A new approach to the design of energy efficient chandeliers with light emitting diodes (LEDs) to illuminate rooms is proposed. The essence of this approach is manufacture of elements of chandelier decorative frame as thermal tubes (TT) and use of light-emitting diode modules (LEDM) installed within them as light sources. TT application allows removing heat from the LEDMs and dissipating it by means of a heat exchange extended surface, which is provided in the TT cooling area. Due to the increase of heat removal efficiency, LEDM power and luminous flux can be increased at least twice in comparison with the correspondent light-emitting diode lamps of direct replacement (DRLEDL).
