The fixed LED bulb of hangers of Universal LED bulb constructive method and liquid fluorescenceTechnical field
the fixed LED bulb of hangers that the present invention relates to a kind of Universal LED bulb constructive method and liquid fluorescence, belongs to LED lighting technical field.
Background technology
semiconductor lighting is as lighting engineering of new generation, have that photoelectric conversion rate is high, light source direction is easily controlled, the period and mode is easily controlled, color rendering properties of light source is high, have the five incomparable large power savings advantages of other existing lighting engineering such as higher power factor under appropriate design of throwing light on, be subject to the favor of global investor and vigorously supporting of national governments.The luminous efficiency of current LED illuminating lamp can exceed 70LM/W mostly, has more power savings advantages than traditional electricity-saving lamp.Green light LED luminous efficiency can be up to 683LM/W in theory; The theoretical efficiency of white light LEDs also can reach 182.45LM/W, and the space that therefore LED illumination efficiency promotes is huge.
in existing high-power LED illumination product design, particularly high-powered LED lamp, due to the reason of heat radiation, when a high-powered LED lamp of assembly, adopt LED optical mode group, driving power and the design of light fixture three in oneization, be that the parts such as LED optical mode group, driving power and light fixture must form a complete production network, formed the situation of so-called " LED has lamp without bulb ".This has brought a series of fatal problems such as manufacturing cost is high, use inconvenience, maintenance difficult for LED illuminating product.First manufacture the upper unified standardization that cannot realize the whole nation and even the whole world and produce, cause product specification many, batch lack, price is high; Next is that the product of each family is of all kinds, not general mutually, more can not exchange; The 3rd need to take off maintenance by overall assemblies such as LED optical mode group, driving power, light fixtures while being product bug, and maintenance is inconvenience very, is very easy to form the defects such as fault extension and maintenance delay, maintenance cost is high.These defects have greatly restricted promoting the use of of LED illumination, are the hard defects during LED illuminating product is promoted.
Summary of the invention
the object of the invention is to, the fixed LED bulb of hangers of a kind of Universal LED bulb constructive method and liquid fluorescence is provided.The bulb that the inventive method forms can work independently, it is independent separately on producing and on using to have realized LED bulb, light fixture and illumination control product, makes LED illuminating product reduce significantly production link, improves production lot, is conducive to the industrialization of LED energy-saving illumination product.
