Description

A kind of LED shot-light
Technical field
The utility model relates to a kind of LED shot-light, relates in particular to the LED shot-light 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.
Lamp develops into second stage, it is mainly the fluorescent lamp that common halogen-phosphate fluorescent material is made, 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.
It is the 1970s and 1980s rare-earth trichromatic fluorescent powder to be applied to energy-conservation fluorescent lamp at twentieth century that lamp develops into the phase III.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.
LED shot-light in the market, specification is uneven, and size is also all lack of standardization.The problem of existing LED shot-light ubiquity excess Temperature, be mainly because the LED electricity conversion is low, and the Conversion of Energy of nearly 80% left and right is heat energy, the LED shot-light is seriously generated heat, and the thermal design of LED shot-light is improper, will cause the LED chip junction temperature too high, shorten device lifetime, and light efficiency reduces.For example some LED shot-light is because volume is little, and area of dissipation is limited, also can cause the heat dissipation problem of this product to be difficult to solve, and has had a strong impact on performance and the life-span of LED.Our company, through large quantity research, adopts unique heat dissipation design, to meet the performance requirement of product.
Environment is many out of doors usually for shot-light, so very high to temperature requirement.Mostly be the many of monochrome concerning the LED shot-light, so normally adding a constant-current driving power supply just can work, the quality of monochromatic constant-current source is very large on the life-span impact of LED shot-light, when ambient temperature raises, LED light source internal resistance meeting reduces, if use the stabilized power source power supply can cause the LED operating current to raise, after surpassing its rated operational current, can affect the service life of LED product, the serious LED light source that will make burns out.For this problem, our company, through large quantity research, adopts advanced non-isolation connection in series-parallel high-efficiency constant-flow power drives technology, is not subjected to the impact of ambient temperature and other factors with the operating current that guarantees LED.
