Description
Technical field
The utility model relates to a kind of LED shot-light, belongs to the LED field.
Background technology
Learn from progressively eliminating the news briefing of incandescent lamp route map that [0002] National Development and Reform Commission, Department of Commerce, General Administration of Customs, State Administration for Industry & Commerce, State General Administration for Quality Supervision unite and printed and distributed " about progressively nonimportation and the bulletin of selling the general lighting incandescent lamp "." bulletin " decision is from October 1st, 2012, according to watt level progressively nonimportation and sale general lighting incandescent lamp stage by stage.
China is the production and consumption big country of illuminating product, and electricity-saving lamp, incandescent lamp output all occupy first place in the world, and adopts efficient illumination products substitution incandescent lamp, and energy-saving and emission-reduction have a high potential.Progressively eliminate incandescent lamp, for promote the optimization and upgrading of Chinese electric lighting industrial structure, promote to realize " 12 " target for energy-saving and emission-reduction task, to respond actively Global climate change significant.Force in market needs us to quicken the development to the LED product of maturation, and the light fixture of processing as light emitting source with LED at present is more and more, wherein tool favorable comment be exactly the LED shot-light because compare with other LED light fixture, LED shot-light price is lower.The LED shot-light uses low-voltage DC to drive, and has the advantage that load is little, interference is weak, requires lower to environment for use; Can control luminescent spectrum preferably and form, thereby can perform well in part or the accent light in museum and the exhibition center.Luminous directive property is very strong, and brightness decay is more much lower than conventional light source, and the response time is very fast, in the microsecond rank, as long as switch one leaves, and at once will be bright, that can not occur postponing and phenomenon flicker.The light ray energy concentration degree of sending is very high, concentrates in the less wavelength window, and purity is high.Life-span is very long, generally between 50,000-100,000 hours, because LED is a semiconductor devices, even frequent switch can not have influence on service life yet; Its feature of environmental protection is good in addition, do not add in process of production " mercury ", do not need inflation yet, do not need glass shell; Good impact resistance, shock resistance is good, is difficult for fragmentation, is convenient to transportation; Very environmental protection is called as " green energy resource ", and the spectrum of LED shot-light almost all concentrates on visible light frequency band, and its luminous efficiency can reach 80～90%.Common people think that it is great beginning that electricity-saving lamp can save energy 4/5, but the LED shot-light is also more energy-conservation 1/4 than electricity-saving lamp, and this is the greater reform of solid light source.
A series of problems such as yet existing LED shot-light ubiquity heat radiation is difficult, photochromic uniformity is not enough, luminous flux is low, shortage security reliability.
Summary of the invention
The invention of the utility model artificially improves the heat radiation of LED shot-light, photochromic uniformity, luminous flux and security reliability, has specially designed a kind of LED of new structure, and it is made up of LED light emitting source, LED driving power, lens, shot-light Lamp cup, lamp holder etc.
Described LED light emitting source is to be formed by one or many core grain COB encapsulation, and preferred directly COB is encapsulated in MPCB (Metal Printed Circuit Board metal base printed circuit board), and more preferably COB is encapsulated on the Metal Substrate of MPCB.Paste on PCB after every core grain of light emitting source of tradition LED shot-light is encapsulated on the support separately, the utility model directly is encapsulated in respect to conventional art core grain on the Metal Substrate of MPCB and is more conducive to the heat radiation of diode tubercle in the course of the work of LED shot-light again.
Described lens are an optical lens, comprise concave-convex lens, planoconvex spotlight, biconvex lens, biconcave lens, plano-concave lens, meniscus or the like, preferred planoconvex spotlight; The plane places on the core grain that is encapsulated on the MPCB, and its minimum must cover all core grains, and its main purpose is that the LED shot-light is collected light through planoconvex spotlight in the course of the work and can be made the concentrated emission of light; Many the shared lens of core grain have not only been practiced thrift operation and have more been practiced thrift cost, and general lens material all is unfavorable for heat radiation; These practical lens directly do not contact with the core grain; Be more conducive to the evacuation of heat in the course of the work of core grain, the service life of also having improved lens simultaneously is because of acrylic, optical grade material Polycarbonate (being called for short PC) Merlon; Non-refractory is prone to produce deformation under high-temperature condition.So the utility model solves traditional LED shot-light the problems referred to above simultaneously.
Basis is practical newly can further to comprise surface-treated lens; These lens are positioned at the convex lens top, and lens surface is treated to roughened, and described surface roughening is handled and comprised atomizing processing, graphical treatment or the like; It has increased the diffuse reflection of light; The light that makes the LED shot-light is during through these lens, the softer free from glare of light and not dazzling, and it can make the photochromic uniformity that has more of the light of LED shot-light.Preferred single face roughened.
These practical new lens are selected from: resin, silica gel, acrylic, glass, actinic glass, optical grade material PC Merlon.
The LED shot-light Lamp cup of the utility model can be the Lamp cup that possesses reflection function in addition, also can be the Lamp cup of heronsbill type, and preferred heronsbill type possesses the Lamp cup of reflection function, can select according to the actual needs of using.
This practical new its lamp holder of LED shot-light is selected from: GU, MR, B, E, PAR, T are the lamp holder of the various models of beginning of letter, like GU10, MR16, MR11, B22, E60, E50, E40, E27, E26, E14, E12, E11, E10, E5, PAR38, PAR30, PAR25 or the like.
The structural representation of this practical new LED shot-light is seen Fig. 1-Fig. 4.
