Description
Technical field
The present invention relates to a kind of LED lighting technical field, refer more particularly to a kind of LED shot-light with honeycomb convection current heat superconducting performance.
Background technology
LED is the solid state light emitter that integrates the plurality of advantages such as luminous efficiency is high, energy-saving and environmental protection, long-life, since being born the sixties in 20th century, just received much concern, through the in recent years lifting of matter and leaping of performance, volume production level LED luminous efficiency surpasses 120Lm/W, replace gradually traditional Halogen lamp LED, fluorescent lamp, sodium vapor lamp etc. and be applied in various lighting fields, it as the 4th generation green illumination light source, existing extensively come into people's life.
LED belongs to photo luminescent devices, is to rely on electron motion and obtain photon from principle LED.World-class chip companies CREE research and development centre information, semiconductor light-emitting-diode (LED) is the same with conventional light source, and LED also can produce heat during operation, and how many heats depends on whole lighting efficiency.Power up outside under the energy, the radiation recombination generation electroluminescent in electronics and hole, semiconductor medium and encapsulation medium that near the light that radiates the P-N knot also need pass through chip (chip) itself just can arrive at external world's (air).Comprehensive electric current injection efficiency, radioluminescence quantum efficiency, chip exterior light take out efficient etc., final probably to only have 30～40% input electric energy conversion be luminous energy, and it mainly transforms heat energy with the form of the lattice vibration of non-radiative compound generation in 60～70% energy.This shows that thermal management is in the LED application product luminous efficiency key issue of high present stage not.
