Description
Technical field
This utility model belongs to LED lamp bead technical field, is specifically related to a kind of Bidirectional LED.
Background technology
Along with the progress of science and technology, lighting develops into Halogen light, high-pressure mercury lamp, fluorescent lamp etc., face from electric filament lamp
Exhibition is not stopped paying out to the direction of energy-saving and environmental protection, low cost.In recent years the LED illumination lamp risen, has theoretical life-span length, energy-saving ring
The advantage such as protecting, technology development space is big, growth momentum is swift and violent.Within 30W, low-power LED lamp design brightness has exceeded identical merit
The brightness twice of the common energy-saving lamp tool of consumption, also reaches more than 5 times of common energy-saving lamp tool projected life.LED lamp is with incandescent
Lamp or electricity-saving lamp are compared, and are the most energy-conservation.Market, hotel, hospital, library, underground parking, shop, road and building
Views etc. are the places that emphasis uses LED illumination lamp.The terminal voltage of PN junction constitutes certain potential barrier, when adding forward bias voltage
Potential barrier declines, and the majority carrier in P district and N district spreads to the other side.Owing to electron mobility is more much bigger than hole mobility, so
There will be a large amount of electronics to spread to P district, constitute the injection to P district minority carrier.These electronics and the hole-recombination in valence band,
The energy that compound tense obtains discharges with the form of luminous energy.Here it is the principle that PN junction is luminous.LED full name is semiconductor light emitting
Diode, uses semi-conducting material to make, and directly to convert electrical energy into luminous energy, electricity number is converted into the luminous organ of optical signal
Part；It is characterized in low in energy consumption, high brightness, beautiful in colour, anti-vibration, life-span length (normal luminous 8-10 ten thousand hours), cold light source etc.
Advantage, is real " green illumination ".Lamp decoration product with LED as light source, in the future of 21 century, necessarily replaces incandescent lamp, becomes
Revolution again for mankind's illumination.But existing Bidirectional LED luminous efficiency has much room for improvement, therefore we need a
Novel LED lamp bead, meets the demand of people.
