Description
Technical field
The utility model relates to a kind of LED lighting, particularly a kind ofly contains integrated LED chip light source device and light conversion film, and the reeded LED light fixture that can be used for room lighting of radiating appliance.
Background technology
Along with the develop rapidly of World Economics, illumination has become an important energy consumption of countries in the world as indispensable part in the daily life.Semiconductor light emitting body light fixture is with regard to its energy-conservation and environmental protection, under the situation of same brightness, the power consumption of LED lamp is 1/8 of an incandescent lamp bulb, is 1/3 of fluorescent tube, and the LED lamp life-span is generally about 50,000 hours, service life of incandescent lamp was generally 1 to 2,000 hour, fluorescent lifetime 5 to 8,000 hours.The LED lamp does not have fluorescent lamp and the contained noxious material of electricity-saving lamp simultaneously, is real nontoxic environment-friendly products.In addition, the LED fixture color is very abundant, can send the shades of colour effect by computer programming, has splendid visual effect in occasions such as the personalized utilization of lighting effects, advertising, light lighting engineering and commercial light.Therefore replace incandescent lamp as lighting source with LED, be described as after Edison's invention incandescent lamp, in the lighting field mankind's another big invention.According to USDOE prediction, before and after 2010, the U.S. will have 55% incandescent lamp and fluorescent lamp to be substituted by semiconductor lamp, can economize on electricity every year 35000000000 dollars.
At present, the LED lamp has been widely used in lighting field, because existing LED light fixture mostly is point light source light-emitting as light source, see through this light fixture and can be clearly seen that spot light, and produce dazzling dazzle, if watch for a long time, cause that easily visual fatigue even eyesight descend.
Secondly, LED light fixture ubiquity list LEDs caloric value is big, cause the problem of its life-span decline, in order to solve heat dissipation problem, the general good heat dissipation effect that adopt of radiator more, cost is controlled, processes easy relatively die casting aluminium fan fin structure, printed circuit board (PCB) adopts metal-cored printed wiring, as aluminium base or copper base.
And because existing packaging technology makes the shortcoming that has the inconsistent and lack of homogeneity of brightness between the White LED, whole light fixture is easy to generate dazzle, the colored lamp color mainly relies on the LED intrinsic colour, change color and must change LED, versicolor LED intrinsic brightness is also inhomogeneous, look declines phase is inconsistent etc.
In order to solve heat dissipation problem, patent CN101179102A proposes to replace epoxy resin to seal in the periphery of led chip with gas, the convection current that utilizes gas to produce is conducted heat outside the lampshade rapidly, the led chip bottom directly contacts with cup in addition, overcome in the prior art led chip and contacted the shortcoming that causes heat-transfer effect not good, made the present invention have splendid radiating effect by a glue and a cup end.Though these improve one's methods big to solving caloric value, problems such as dazzle have certain effect.But it is single that it fails to solve single LEDs color, and the uneven problem of overall brightness simultaneously in order to solve the problem of heat and dazzle, has been brought the processing technology complexity, the shortcoming that cost significantly increases.
, lack of homogeneity inconsistent for the brightness that improves conventional white light LED light fixture, colour temperature easily departs from and the shortcoming of colour rendering difference, utilize carriers such as glass, plastics, film among the patent CN200993322, combine the formation special material with fluorescent material, and use the blue led light source to excite, make above-mentioned optical problem obtain improvement to a certain degree.But, because LED quantity is few, so this type lamp brightness is on the low side; Fluorescent material combines with glass and plastics, makes fluorescent material content increase, and has improved the cost of this light fixture; The combination of light source and three kinds of materials has in addition limited the size of LED light fixture, also inaccessible good illumination and optical effect.
Patent of invention CN101017814A for another example, the method of the existing white light LEDs defective of several solutions is proposed, film class application mode wherein, though improved the defective of white light LEDs, corresponding invention structure not well and optical design in conjunction with application, and version is single, use underaction, can not on existing light fixture, conveniently use, have the limitation of range of application, can not satisfy the extensive use of existing various LED light fixture.
Combine with the integrated LED chip light source device by light conversion film, and be applied in the LED lighting, solved effectively because semiconductor chip generates heat to harmful effects such as excitation wavelength skew, quantum efficiency that light-converting material caused descend, wear out; Light emission rate, colour temperature, colourity and the uniformity etc. of the LED light fixture of making have also obtained effective improvement; And can effectively prevent glare phenomenon.
Wherein the light conversion film among the present invention is made of diffusion barrier and compo layer thereon, the compo layer is made up of Yellow luminous fluorescent material and/or emitting red light fluorescent material, fluoropolymer resin, two amino silane, diluent and auxiliary agent, wherein: described Yellow luminous fluorescent material is excited by the blue-ray LED of emission spectrum in 440～475nm scope as excitation source, absorbs to inspire the emission spectrum of at least more than one peak wavelength in 525～580nm scope;
Described emitting red light fluorescent material is excited by the blue-ray LED of emission spectrum in 440～475nm scope as excitation source, absorbs to inspire the emission spectrum of at least more than one peak wavelength in 580～650nm scope;
The light of the synthetic white of the recovery that light and blue-ray LED sent that Yellow luminous fluorescent material and emitting red light fluorescent material are sent.
Summary of the invention
