This routine structural principle is:
1, light distribution structure principle
The lamp pearl that is installed on the lamp plate on the luminous intensity distribution radiator kerve 55 sends the plane directional light after energising, because kerve, two secondary reflecting faces and lampshade have formed airtight reflective cavity, the part scattered light of plane directional light just reflexes to the place that needs illumination by the secondary reflecting face, so reaches the purpose of secondary light-distribution.This measure has improved the utilization rate of light greatly.
2, radiator structure principle
Be installed in lamp pearl on the lamp plate on the luminous intensity distribution radiator kerve 55 after energising, part electric energy is transformed into luminous energy by quantum effect and reflects away, but most of electric energy passes on the lamp plate because of the existence of resistance in the lamp pearl has become heat energy, because lamp plate pastes tightly mutually with luminous intensity distribution heat abstractor kerve, so energy is very fast passes to luminous intensity distribution heat abstractor kerve 55 by lamp plate.Kerve 55 lower ends of this moment have each reinforcement 53 that links to each other with luminous intensity distribution heat abstractor outer wall of divergent state again, and heat can directly pass on the reinforcement 53, and then pass device wall and be dispersed in the atmosphere.Guaranteed that finally the lamp pearl is operated in the temperature range of permission.
The invention provides a kind of LED fluorescent tube luminous intensity distribution heat abstractor, luminous intensity distribution heat abstractor upper end draw-in groove can with the lampshade clamping, to form an integral body, luminous intensity distribution heat abstractor two ends then are fixed with lamp holder by screw.Compared with prior art, the present invention combines the light source secondary light-distribution cleverly with heat radiation, be designed to an integral body, described LED fluorescent tube luminous intensity distribution heat abstractor is provided with the angled secondary light-distribution face that calculates through precision, post reflecting piece on the secondary reflecting face, make the part scattered light reflex to the place that needs illumination, improved the utilization rate of light by reflecting piece; The existing reinforcement effect of luminous intensity distribution heat sink interior reinforcement has also played good conductive force simultaneously.This structure luminous intensity distribution heat abstractor has been simplified the device of light source secondary light-distribution and heat radiation, technology difficulty of dwindling greatly and material cost.
