Definitions

  • LEDs light emitting diodes
  • LEDs provide numerous advantages such as a longer operational life, a reduced power consumption, and an increased efficiency related to the ratio between light energy and heat energy.
  • LED-based lighting solutions there is currently a very large interest in lighting devices and/or arrangements (such as lamps) provided with LEDs, and incandescent lamps are rapidly being replaced by LED-based lighting solutions. It is nevertheless appreciated and desired to have retrofit lighting devices (e.g. lamps) which have the look of an incandescent bulb. For this purpose, it is possible to make use of the infrastructure for producing incandescent lamps based on LED filaments arranged in such a bulb. In particular, LED filament lamps are highly appreciated as they are very decorative.
  • LED filament lamps comprising one or more reflectors. More specifically, LED filament lamps according to the prior art may have an unsatisfactory efficiency.
  • one or more of the LED filament(s) 120, the reflector element(s) 200, 300, etc. may have different shapes, dimensions and/or sizes than those depicted/described.
