The LED panel lamp has the beneficial effects that the ceramic circuit board is formed by printing a circuit layer on a ceramic plate by utilizing a screen printing technology through high temperature sintering, so that the integral service life of the lamp is prolonged; the LED lamp beads are uniformly embedded at the inner periphery of the die-casting aluminium sash, so that the light rays emitted by an LED light source are uniformly reflected, the lateral light-emitting angle is changed into the front light-emitting angle, so a uniform face light source is formed, meanwhile, the utilization ratio of the light is improved, and the light-emitting space is larger; the rear cover is provided with the constant current power supply driver, so that light rays of the LED panel lamp are bright, the radiating effect is good, and the service life of the lamp is prolonged.
Description
Technical field
The utility model relates to a kind of LED flat lamp, relates in particular to the LED flat lamp in a kind of photoelectric lighting field.
Background technology
Since 19th-century Edison invented incandescent lamp, brought in the dark bright and happy to the mankind.But because service life of incandescent lamp is short, electro-optical efficiency is low, and most of electric energy is used for generating heat, and small part is luminous, so energy consumption is large, at current Energy-saving Society, will withdraw from gradually electric light source main flow illumination market.European Union progressively eliminates the application of incandescent lamp since on September 1st, 2009.
Second stage, the fluorescent lamp that common halogen-phosphate fluorescent material is made is after the course that has experienced nearly 60 years, although also exist many defects, in constantly improvement, improve among the superiority of its quality, price make it in market always in occupation of suitable share.
Phase III, at twentieth century, the 1970s and 1980s rare-earth trichromatic fluorescent powder is applied to energy-conservation fluorescent lamp.With respect to incandescent lamp, power saving fluorescent lamp is because its light efficiency is high, and the life-span is long, and obvious energy conservation becomes the major product of twentieth century whole world Green Lighting Project.But, by ultraviolet excited light-emitting, there is harmful mercury element in fluorescent lamp, not environmental protection; Stroboscopic; High pressure,, there is potential danger in activated phosphor; Therefore the shortcomings such as ballast and starter power consumption are large are not still a kind of very good green illumination electric light sources.Along with the time is put off also and will be eliminated gradually.
Along with the electric light source scientific technological advance, semiconductor light-emitting-diode (LED) sixties appearred in twentieth century.Through decades development, LED has obtained the technical important breakthroughs such as extension, chip in the nineties, become the 4th generation electric light source, start to enter the practical stage, and demonstrate the large advantage of its tool: optical efficiency is high; The light quality is good; Energy consumption is little; Life-span is long; Reliability and durability; Applying flexible; Safe and reliable; Environmental protection; Response time is short.Particularly through in recent years development, LED is just attracting global sight with its intrinsic superiority., for the application of LED, at the extensively universal of general lighting field, be that people expect the most in the world.At present, the application of illumination LED is confined to the particular forms such as local lighting, decorative lighting, outline lighting, and people wish that urgently LED becomes general lighting light source of new generation, and each illumination company is all at the active development Related product.In addition, many buildings and Lighting designer are thought, use LED to can be them and increase many new designs, and they can utilize LED that the inspiration of oneself and design are specialized, so and the design sample that produces can be watched for people easily, this also is very beneficial for popularizing of LED.With the perfect fusion of manufacturer, designer and user's imagination, the new application that developing traditional lighting light source can't be realized is most important.Along with the LED technology further develops, LED will become the revolutionary green illumination of 21st century mankind a new generation electric light source, will be global Lighting Industry prior development direction from now on.
Traditional LED encapsulating structure, be generally with conduction or non-conductive adhesive is contained in chip in undersized reflector or on slide holder, forms with epoxy encapsulation completed the inside and outside connection of device by spun gold after, and its thermal resistance is up to 250～300 ℃/W.If adopt the LED packing forms of traditional type, will cause because heat radiation is bad junction temperature of chip to rise rapidly and epoxy carbonization flavescence, thereby cause the acceleration light decay of device until lost efficacy, even because causing open circuit, the stress that thermal expansion rapidly produces lost efficacy.
