The replacement series of infrared power LED products thirteen where thesemiconductor power infrared LED’s research has made many achievements in scientific research. LED high bay Including tanks, night vision equipment to replace the incandescentGaAs power infrared LED; DC 1A, work in pulse 24A InP-power infrared LED,dedicated to the single crystal silicon minority carrier lifetime tester, led light battery, replacing thevacuum light . MOCVD epitaxial growth techniques recently developed a power infrared LED with a resonant cavity structure for military targeting systems, complete theupgrading of the product. At the same time has become a series of infrared LED products including the F004 type, F005, F006 type can be applied to the infrared range,type 761, led light battery, the peak wavelength from 900nm to 1100nm, the optical output power from10mW to 180mW, the beam angle from 38 ∘ to 170 ∘ , infrared night vision, infrared communication, points of light automatic control, led light battery, and optical coupling.
The visible power LED luminous efficiency of single-chip 1W single-chip power LED to achieve a new level 13 developed complete product designs have been finalized.Design and production of a proprietary ceramic-metal tubes used for power LED singlechip package shell, and carried out the package case studies include: the current distribution and heat distribution of the various structures of large-size LED power chip ;led light battery, different solder alloys and conductive paste bonding power chip thermal resistance;different potting reliability; eutectic solder and glass microlens production process. F002type shell and tube packaging design and production of white power LED light source, as shown, the luminous efficiency is generally above 30Lm / W, up to 38.6Lm / W;luminous flux in 43Lm above, up to 51Lm, color temperature 3000-8000K, color rendering index of 80 or above,led light battery, the thermal resistance is generally lower than 20 W / ° Ccan be used for special lighting, such as miner’s lamp, reading lights, emergency lights, flashlights and so on.
