Description

One kind can shaft LED lamp

Technical field

The utility model belongs to LED lamp technical field, and in particular to one kind can adjust direction of illumination, and illuminating effect is more Good can shaft LED lamp.

Background technology

LED lamp, also known as LED lamp, the technical characterstics such as, energy saving, long-lived, small and exquisite efficient with its, are becoming Main force's product of illumination market of new generation, and effectively pull the high speed development of environmental protection and energy-conservation industry.Semiconductor light-emitting-diode Lamps and lanterns, that is, LED (Light Emitting Diode) lamps and lanterns, are a kind of semiconducting solid luminescent devices.It is partly led using solid Body chip causes photon to emit by the compound energy for releasing surplus occurs for carrier in the semiconductors as luminescent material, Directly send out red, yellow, blue, green, green, orange, purple, white light.LED illumination product is exactly to be manufactured using LED as light source Luminaire.Certain potential barrier is constituted in the terminal voltage of the PN junction of its chip when work, when adding forward bias voltage under potential barrier The majority carrier in drop, the areas P and the areas N is spread to other side.Since electron mobility is more much bigger than hole mobility, so will appear A large amount of electronics are spread to the areas P, constitute the injection to the areas P minority carrier.These electronics and the hole-recombination in valence band, compound tense Obtained energy is discharged in the form of luminous energy.Here it is the principles that PN junction shines.The worry of Present Global energy shortage is again It spends under raised background, energy saving is the important problem that we will face in future, and in lighting area, LED luminous products are answered With the sight that just attract common people, LED is as a kind of novel green light source product, the necessarily trend of future development, and 20 Century will enter using LED as the novel illumination light source epoch of representative.LED is referred to as forth generation lighting source or green light source, Have the characteristics that energy-saving and environmental protection, long lifespan, small, can be widely applied to various instructions, display, decoration, backlight, general The fields such as logical illumination and urban landscape.In the world some developed countries around LED developments expand fierceness technology it is competing Match.The U.S. invested 500,000,000 dollars of implementations " National Semiconductor illumination plan " from 2000, and European Union also announces to open in July, 2000 Dynamic similar " rainbow plan ".The Department of Science and Technology of China is put forward for the first time development in June, 2003 and partly leads under the support that " 863 " plan Body illumination plan.With the gradually development of LED illumination lamp, in public arenas such as lighting engineering floor lights, LED illumination lamp Gradually instead of some conventional light source products.2009, LED lamp started to enter key lighting in developed country universal.As LED The purposes of illuminator, LED market developments point several stages.

First stage, LED lamp replacement receive the stage.This stage refers to LED lamp in the early stage of development, major embodiment Go out its light efficiency it is high (, the characteristics of long lifespan.It is mainly that quotient shines market in this stage because price is high.There are one connect client The process received is use habit and apparent transition and receiving first.Under the service condition consistent with conventional light source, LED The economize on electricity that lamps and lanterns embody, it is long-lived the features such as make its acceptant opposite high price of market.Especially in commercial applications.Each factory What quotient spelled is quality price advantage.

Second stage, LED lamp utility model stage.On the basis of on last stage, there is LED lamp product in market Certain recognition and acceptance.The environmental protection of LED lamp, small, other characteristics such as high reliability gradually highlight.It opens therefrom A series of products for being different from conventional light source application completely of hair can propagate its belief on a large scale.Illuminating industry will appear wider array of one of bigger Development space.Light source is no longer to function only as illuminating effect, its changeable point drop made in properer people's Working Life Drop.What each manufacturer spelled is design application advantage.

Phase III, LED lamp intelligent control stage.With the development of the new technologies such as Internet of Things, LED is as semiconductor product Industry will also cost this bullet train, play its high controllability feature.From family to office building, from road to tunnel, from vapour Vehicle is to walking, and from floor light to key lighting, the LED illumination lamp system for having intelligent control will bring greater degree to the mankind Service.

It is predominantly fixed at present based on the main fixed round or bar shaped of current market sales of LED lamp, it is right It is inconvenient in having under special mounting or lighting conditions, this LED lamp be can pivot design, can meet it is more under the conditions of make With.
