Abstract
The invention relates to a structure for improving glare of an LED light source and a manufacture method for the structure. Such methods as machining, laser processing or etching and the like are used, so that light refraction stripes are formed on the surface of LED light source encapsulating material. The light is uniformly scattered out by the light refraction stripes on the surface of the LED light source encapsulating material, thereby improving a glare phenomenon caused by uneven luminescence of a chip or fluorescent powder.
Description
Technical field
The present invention relates to a kind of luminous original paper and manufacturing approach thereof, especially relate to a kind of structure of improving the led light source dazzle and preparation method thereof, belong to light-emitting diode manufacturing technology field.
Background technology
Semiconductor light-emitting-diode (Light Emitting Diode; Be called for short LED); It is a kind of solid-state semiconductor device that can electric energy be converted into visible light; It can directly be converted into light to electricity, and it is different from the luminous and luminous principle of electricity-saving lamp tricolor powder of incandescent lamp tungsten filament, and adopts electroluminescence.It has that volume is little, power consumption is low, long service life, high brightness, low in calories, environmental protection and advantage such as sturdy and durable; Make LED throw light on this high energy efficiency lighting technology, nowadays all extensively adopting the LED light fixture to flood light, floodlight again from various indicator lights, street lamp, Colour lamp for fastival and holiday, bulkhead lamp capable since the just application of the seventies in last century six.Because its high energy efficiency, people generally believe that replacing traditional bulb, fluorescent lamp with the LED lamp is a kind of way of very environmental protection.
The bulb lamp that room lighting is used, shot-light, ceiling light are for life brings light; Underground lamp, floodlight or the flood light of extensive uses such as mansion, greenbelt, park, sculpture, square are that the city has increased beautiful scenery in the outdoor lighting.Yet many times we can not feel well because of these light, and this is because light fixture produces the effect of dazzle, make to produce the light sensation that human eye can't adapt in the visual field, even possibly cause detest, uncomfortable forfeiture legibility.Dazzle (glare) is meant in the visual field because unsuitable Luminance Distribution; Or there is an extreme brightness contrast in the space or on the time; So that cause vision uncomfortable with the visual condition that reduces the object visibility, its structure such as Fig. 1 and shown in Figure 2 comprise chip 1-3; The gold thread 1-2 and the encapsulating material 1-1 that are arranged on the chip form led light source, and encapsulating material shows smooth.
Up to the present, several kinds of technological means below the realization of anti-dazzle is mainly adopted:
1. add glare filter.Method through adding glare filter can effectively be improved dazzle, and simple in structure, and cost is lower, is fit to produce in batches; But glare filter Core Feature assembly is a nonglare sheet, and its transmitance can not reach 100%, thereby can cause light losing.
2. add anti-dazzling film or Anti Glare Coatings.Need special preparation technology and material, and with add that glare filter is the same can to cause light losing.
3. fitting structure optimization.Light fixture to specific is optimized design, like glare prevention LED fluorescent lamp etc., makes lampshade itself have scattering function.Its shortcoming is that application surface is narrow, can only be directed against specific light fixture.
Summary of the invention
In order to overcome the existing defective of led light source in the prior art; Technical problem to be solved by this invention provides a kind of structure of improving the led light source dazzle; Form the light refraction striped on said led light source encapsulating material surface, the light that light source is sent is dispersed equably.
The technical scheme that the present invention solves the problems of the technologies described above is following: a kind of structure of improving the led light source dazzle, the encapsulating material surface of said led light source is provided with the light refraction striped.
The invention has the beneficial effects as follows: the encapsulating material surface at said led light source is processed to form the light refraction striped, and the light that light source is sent is dispersed equably.The function of existing glare filter or anti-dazzling film is integrated in the said led light source, reduces requirement, reduce the cost of glare filter, improve transmitance simultaneously glare filter.Further, need not to add glare filter or anti-dazzling film in addition, saved material cost and avoided because of adding the light loss that the anti-dazzle material causes.
On the basis of technique scheme, the present invention can also do following improvement.
Further, said light refraction striped is the horizontal stripe shape.
Further, said light refraction striped is latticed.
Further, said light refraction striped is a concentric circles.
Said light refraction striped also can be spiral-shaped, the combinations of striped polygon-shaped, that be made up of little point or above-mentioned any two kinds or several kinds of shapes with one heart.
Said light refraction striped also can be the light refraction striped of regular shape.
The present invention also provides a kind of method of improving the led light source dazzle, may further comprise the steps:
(1) through encapsulating material led chip is encapsulated, form led light source;
(2) be processed to form the light refraction striped on the encapsulating material surface of said led light source.
Further, said led light source forms for formal dress, upside-down mounting or light emitting diode (LED) chip with vertical structure are encapsulated, and said led chip is not limited to above three kinds of structures, also can adopt other all encapsulating structures that are fit to.
Further, said light refraction striped is through machining, and the method for laser or etching is processed to form, and described light refraction striped also can all modes that are fit to process through other.
Further, said encapsulating material is one or several in epoxy resin, silicones, glass, pottery, crystal and the plastics.
