Description
Technical field
The present invention relates to a kind of LED, particularly a kind of high-power LED lamp with far throw ability.
Background technology
Metal halogen lamp is current one of classic electric light source in the world, and it has specular removal (65 ~ 140lm/w), the long-life (5000 ~ 20000h), colour rendering good (Ra65 ~ 95) feature such as compact conformation, stable performance.It has concurrently fluorescent lamp, high-pressure sodium lamp, high-pressure mercury lamp advantage, overcome the defect of these lamps, Metal halogen lamp summarizes the major advantage of glow discharge spot lamp.Especially light efficiency is high, the life-span long, photochromic three large advantages. and therefore Metal halogen lamp development is very fast, and purposes is more and more wider.Metal halogen lamp on market is the same with other gas-discharge lamp, has mercury in the filler in lamp, and mercury is noxious material, during lamp note mercury processed, process accidentally, can cause and pollute production environment, damage the healthy of workman, during electric arc tube exhaust, there is the mercuryvapour of trace to discharge, if deal with improperly, directly can enter air, when the lamp used is damaged, all can to environment.By the mixture radiation of analyte of metallic vapour (such as mercury) and halide (halide as elements such as dysprosium, sodium, thallium, indiums) and the gas-discharge lamp of luminescence.Have the characteristic light spectral line adding metal, thus photochromic improvement, also improves light efficiency.About the correlated colour temperature 4000K of this kind of lamp, colour rendering index 70, light efficiency is at more than 701m/W.
Metal halide lamp product parameters adopts the unique olive-shaped configuration design of electric arc tube leading in the world, can bring splendid photochromic uniformity.Effectively solve the COLOR COMPOSITION THROUGH DISTRIBUTION uneven phenomenon because photochromic drift causes.Adopt the rack mounting structure of no-welding-spot, the support solder joint fracture because high-temperature oxydation or vibration cause can be prevented, more improve the reliability of bulb.Electric arc tube by the restriction of working position, can not realize the burning-point of optional position.Luminous efficiency is high, higher by 20% than common Metal halogen lamp light efficiency.The average light efficiency of HPl400/ED/UP/4K is at 110lm/w.Rational some lamp driver uses, has better protective effect to the electrode of lamp, the service life of lamp can be made more lasting.The longlyest reach more than 20000 hours.Specular removal and long-life, the quantity using light source, electrical equipment and light fixture can be reduced in engineering, reduce the number of times of replacing bulb, thus reduce overall maintenance cost.Be applicable to vertical burning-point and horizontally lighted, vertical burning-point better effects if.What be best suited for the higher place such as factory building, large-scale sales field, shopping center, building, advertisement, airport of photochromic coherence request is bright.
But because the problem in above-mentioned is as having mercury in the filler in lamp, mercury is noxious material, during lamp note mercury processed, process accidentally, can cause and pollute production environment, damage the healthy of workman, during electric arc tube exhaust, there is the mercuryvapour of trace to discharge, if deal with improperly, directly can enter air, when the lamp used is damaged, all can to the problem of environment, it is higher that people have turned one's attention to efficiency, the LED replacement metal halide lamp that the life-span is longer.
But powerful led is by the restriction of technique, list only can only accomplish 5w at present, wants to accomplish that more than 30w's is high-power, is usually realized by many LED strip connection or joint in parallel.
When many LED strip connection or parallel connection, each lamp will have good radiator heat radiation, and to ensure the life-span of LED, due to distance dispersion, improving overall far throw ability needs good optical lens to coordinate, and this not only makes cost increase, and also makes process complications.
COB technique effectively can improve the problems referred to above, but single lens want that the effect realizing Metal halogen lamp is very difficult.Set of lenses makes again cost increase.
