Description
Technical field
The invention belongs to the luminous field of LED, relate in particular to a kind of LED dual-side emissive flat lamp with secondary control.
Background technology
Semiconductor light-emitting-diode (LED) since its excellent performance by people regard as after incandescent lamp, fluorescent lamp and high-voltage gas discharging light the 4th generation lighting source.White-light LED illumination not only power consumption helps simultaneously energy savings, reduces the CO2 discharging far below incandescent lamp and the fluorescent lamp of equal brightness of illumination, and the environmentally harmful heavy metal such as not mercurous.White light LEDs is photochromic pure and concentrate on visible region in addition, has eliminated the harm of non-visible light district electromagnetic wave to human body.White light LEDs is because its unique advantage, is expected to the conventional light source such as replace incandescent, fluorescent lamp and becomes " green light source of 21 century ".
Along with the raising of living standards of the people, also improving constantly for the requirement of lighting source, especially the Landscape Lighting of reading lighting, room lighting, public place not only has certain requirement to brightness, for light pollution certain requirement is arranged also.
The electric light source of existing light fixture is of all kinds, and can be divided into spot light, line source and expansion light source (claiming again the extension light source) by the size of illuminator is area source lamp.The direct glare that existing point light source light-emitting body light fixture produces is exactly a kind of main light pollution source, present LED light fixture generally adopts the lampshade of complete wear sand glass or grid type, litura light source luminescent point, the luminous energy loss is larger like this, also adopt white plastic or the translucent fabric lampshade that have overcome the direct glare that spot light produces, not only the luminous energy loss is larger, and very dangerous.Existing fluorescent lamp line source and ac electroluminescence area source lamp, though it can overcome the direct glare that the point light source light-emitting body produces, but because its processing technology is complicated, cost is higher, particularly the ac electroluminescence area source can only be made into the area source of low-light (level), still can not generally promote the use of.
Area source lamp is exactly to produce direct glare in order to overcome LED point light source light-emitting body, and the LED area source lamp of present various technical schemes progressively enters lighting field, and the LED panel light is exactly wherein a kind of.The LED panel light is because the focus of its good looking appearance, advantage becomes gradually people's research such as easy for installation, light is soft.
The LED flat lamp adopts unique paster LED as lighting source, add LGP and (or) diffuser plate, make light soft not dazzling, illumination is even, and brightness is high, and its ultra-thin thickness can not only provide illumination, and increase artistic aesthetic feeling, very popular in recent years.The at present main use occasion of LED flat lamp has office lighting, classroom illumination, analyse, hotel's illumination, also can be applicable to show the Room, family parlor etc., intersperses environment, creates science and technology sense and stylishness.
Main Problems is that LED flat lamp colour temperature is too high, colour rendering index is excessively low in the case that has been applied on the market, as is applied in indoorly, and for a long time words can produce fixed negative effect to human eye or psychology.
The LED flat lamp ubiquity capacity usage ratio that has existed at present is low, uniformity is bad, and driveability is poor, and large problem decays.On the one hand be since light emitting diode manufacturing technology itself also at development, its power efficiency (Wall-Plug Efficiency) space that still has greatly improved; Heat dissipation technology itself is also at development, actuation techniques is also at development, the efficient (abbreviation secondary efficiency) that on the other hand the light emitting diode spot light is changed into practical surface light source device is also lower, and the leaded light efficient of LGP low be a major reason.At present openly report proposed respectively different LGPs with and scattering mechanism layer structure, and directionality and the leaded light efficient of LGP emergent light made improvement in varying degrees.Yet according to the bibliographical information of academic journal APPLIED PHYSICS upper the 83rd phase of LETTERS (2003), the highest level of the leaded light efficient of existing LGP is merely able to reach 60%, and its scattering machine preparative layer is the reflection microprism array.The invalid bright dipping of this LGP is less, and the rising angle of effective bright dipping has been realized better control; Leaded light efficient is not high and making is difficult, the high in cost of production problem but it still exists.Existing LGP for primary source design all is at LGP interarea arrangement certain scattering machine preparative layer relative with the outgoing interarea, utilizes light to incide that scattering unit changes original reflection path and from the outgoing of outgoing interarea.Although can maximize leaded light efficient by optimal design scattering machine preparative layer and scattering unit, but be invalid emergent light owing to light inevitably can form from the interarea transmission outgoing relative with the outgoing interarea, so there is the upper limit of a principle in its leaded light efficient and can not reaches higher.
Design and fabrication technology and the backlight technology of LGP are closely bound up, also are in the budding stage in China.
Chinese patent CN101608787A discloses a kind of LED flat lamp, comprise LGP, be located at the LED luminescence unit of both sides, LGP front and back and be located at LGP both sides, front and back and the heat sink section bar corresponding with the LED luminescence unit, this heat sink section bar inboard is provided with the capable groove of T that extends along the profile length direction, the outside is provided with some fin, LED luminescence unit and LGP edge are embedded in the T-slot, each fin is outwards done the extension of amplification from bottom to top along heat sink section bar, improve heat dispersion.But still there is complex manufacturing technology in this LED flat lamp structure, cost is high, cost performance is low, taking up room also is unfavorable for more greatly installing, poor radiation, driveability are poor to cause the led decay large, and adopts high-voltage electrolytic capacitor to cause the problems such as service life is short.
