For the above and other objects, features and advantages of the present invention can be become apparent, it is cited below particularly go out preferred embodiment, and coordinate institute's accompanying drawings, be described in detail below.

The PCT Patent Application PCT/CN2007/001966 and PCT Patent Application PCT/CN2006/003037 that the present embodiment is incorporated to applicant herein are referred to as the present invention.

In the following example of the present invention, the manufacture method of main production method, the illuminating module with reflective structure and its heat-conducting mode for illustrating bearing substrate respectively, the lighting apparatus of multiple illuminating modules combination and illuminating module, but the embodiment is merely to illustrate the present invention and is not used to limit the scope of the present invention.

In this manual, so-called " reflective structure " refers to an enclosed construction.In an embodiment of the present invention, though enumerating rectangle such as rectangle or square, the reflective structure area defined for being not limited to the scope of the present invention , Round shapes also may be used；And in other embodiments, area i or can also be other arbitrary shapes that this reflective structure is surrounded.

Reflective structure used in embodiments in accordance with the present invention, can assemble the light sent from the luminescent grain side.And luminescent grain can be made up of the light emitting diode that can send particular light ray, without modular luminescent grain, typically refer to the luminescent grain and be not equiped with adhesive layer or reflective cup, or be a crystal grain.In addition, the row of luminous row refer to the space formed substantially along a specific direction, and it is not limited to longitudinally, laterally or straight line.

Illuminating module with reflective structure

Figure 1A illustrates the illuminating module with reflective structure of present pre-ferred embodiments.Illuminating module 100 includes a shared bearing substrate 102, to carry at least one luminous row 130, each luminous row 130 include multiple without modular luminescent grain 104, such as LED crystal particle, and each luminous row 130 are surrounded by a reflective structure 110, and reflective structure 110 includes the column space of the above-mentioned luminous row 130 of correspondence, with fixed multiple luminescent grains 104 on the bearing substrate 102 in column space.In another embodiment, each luminous row can further include an inner covering layer 108 for being bonded in reflective structure 110 and being covered with above-mentioned multiple luminescent grains 104.Without modular luminescent grain, Typically refer to the luminescent grain and be not equiped with adhesive layer or reflective cup, or therefore the area needed for crystal grain, therefore illuminating module can reduce.In addition, because many luminescent grains are divided into multiple row configuration, and surrounded respectively by the reflective structure of multiple row, therefore, the situation only surrounded compared to whole luminescent grains by a cyclic structure, each luminescent grain of each column and the spacing of reflective structure are not only shorter, and are relatively easy to make the light sent expose to adjacent reflective structure and be difficult to be stopped by other luminescent grains. ·

In addition, optionally (optionally) further includes one and is placed in same column to cover the luminous material layer 106 on multiple surfaces of luminescent grain 104 at least one luminous row, for example it is made up of phosphor particles material, in one embodiment, the covering of luminous material layer continuity is described without modular luminescent grain 104 and extends on the madial wall of the reflective structure.In a specific examples, at least part of luminous material layer 106 can be for example bonded to condense phosphor particles blocking and without sticker by drying mode formation Van der Waals force, in this example, luminous material layer（Fluorescent material granulosa）The upper surface and side of each luminescent grain 104 of 106 complete covering same columns.In another example, illuminating module can further include one and be bonded in reflective structure 110 and be covered with the inner covering layer 108 of above-mentioned luminous material layer 106 to be used as protective layer.

Wherein, the area defined of reflective structure 110 can be polygon, and such as rectangle or pentagon also can be circular or ellipse.Please with particular reference to the schematic diagram of reflective structure 110 shown in Fig. 3.

In general, inner covering layer（Protective layer）108 making except can by being coated with the soft high polymer materials such as silica gel (silicone) in addition in reflective structure, also can be used Bohemian glass layer, epoxy resin or other transparent plastic materials layer, such as makrolon（PC:) or polyethylene (PE Polycarbonate:Polyethylene) material, is pressed on luminescent grain 104 or luminous material layer 106 with being embedded in reflective structure 110.So luminous material layer can be avoided to come off or prevent aqueous vapor from penetrating into.

Because reflective structure 110 can be used to adjust the direction from the emitted light of luminescent grain 104, for example cover, reflect, collect or focus on, therefore when luminous material layer 106 does not cover all luminescent grain side, the problem of can still solving the light leakage phenomena of the side of luminescent grain 104, and improve light colour cast. Reflective structure 110-as the metal material with reflecting surface or can be a plastic body, surface can then form a reflective material layer, the reflectorized material such as one layer of chromium of selection plating, nickel, silver, zinc fluoride or magnesium sulfide.

Wherein, because reflective structure 110 and luminescent grain 104 are arranged on the same face, so if selection heat dissipation characteristics preferably material, such as polishing forms the metal material with reflective surface, then can improve radiating efficiency.

Furthermore, it is possible to set a lens 200 on above-mentioned luminous row, it covers bearing substrate 102, luminescent grain 104, protective layer 108 and reflective structure 110 to adjust light one light source of formation of the luminous row.Lens component with addition to original silica gel material can also use other materials instead except sustainable, because lens are more particular about translucidus, therefore PC or PE perspexs（Plastic), acryl (Acrylic), glass（Glass), makrolon（) etc. Polycarbonate it can also use, and degree is relevant with wavelength thoroughly for light, different wavelengths of light spends difference thoroughly, and lens also can be colored lens, to increase photochromic contrast.In one embodiment, lens 200 can be sealed on the housing of bearing substrate 102 or reflective structure 110 so that formed in a closed chamber, closed chamber can be for a vacuum environment or filled with inert gas, to maintain the stabilization in closed chamber.In another embodiment, it can refill another inner covering layer in the closed chamber of the top of protective layer 108 further to fill up each reflective structure and its superjacent air space to prevent water gas from invading.Or in another embodiment, first do not form protective layer 108, but be covered in lens after bearing substrate, be directly injected into silica gel with cover fluorescent material granulosa simultaneously backfilled enclosed chamber and form the protective layer for being integrally formed and existing without interface.

In another embodiment, the madial wall of reflective structure 110 forms an angle, θ, and 0 with the surface of bearing substrate 102.< θ < 90., but with θ=45.Preferably；The material of reflective structure 110 is metal, e.g. stainless steel material；Or the material such as plastic cement or resin, such as silica gel material can also use other materials, therefore PC or Ρ Ε perspexs instead in addition（Plastic), acryl（), Acrylic glass（Glass), makrolon（) etc. Polycarbonate it can also use, then select one layer of plated film to form reflecting effect then at the surface of reflective structure 110.

Especially in a specific examples, between the phosphor particles in fluorescent material granulosa 106 and without glue, Therefore luminous efficiency can be increased.Wherein, the crystal grain quantity of luminescent grain 104 is determined according to needing；In this example, this crystal grain is light emitting diode.

In addition, in other embodiments, the shape of the area defined of reflective structure 110 can be also properly changed according to needs, e.g. rectangle, Round shapes or other shapes etc.；And reflective structure

110 shapes of itself can also do any change, such as its section shape can be trapezoidal, triangle or arc.In other embodiments, this reflective structure area defined can also be other arbitrary shapes, for example, coordinate the space of backlight module to manufacture appropriate strip reflective structure.

Bearing substrate

Figure 1A is referred to, bearing substrate 102 can be a metal material, such as aluminum metal in the present embodiment.But it is not limited thereto, in other embodiments, such as carbofrax material or ceramics or the good ceramic material of other thermal conductivitys containing alundum (Al2O3) can also be used.In addition, in this example, as shown in Figure 1B, bearing substrate surface can separately form the metal dielectric layer 160 of a hole comprising multiple exposures, such as a metal oxide layer.A kind of embodiment is that μ η ι -50 μ of thickness about 30 porous alumina layer 1 is formed with anode processing on the surface of aluminium base 3, porous alumina layer 1 includes multiple honeycomb holes 4, is isolated between aluminium base 3 and porous alumina layer 1 by a barrier layer 2.

Above-mentioned embodiment, due to metal dielectric layer 160 and bearing substrate 102 can be made to combine closely, therefore thermal resistance reduction, heat transfer efficiency can be improved, that is, above-mentioned bearing substrate is due to preferably heat transfer efficiency, therefore the present embodiment is the problem of can improve many crystal grain issuable radiating is difficult on the same substrate.

It is worth noting that, by the porous metals insulating barrier formed is before without sealing pores, there is hardness softer or there is the characteristic of easily sticky impurity on its surface, therefore, those skilled in the art are before the substrate after being intended to handle on anode carries out subsequent applications or processing (as formed circuit pattern what follows), one of sealing of hole processing procedure can be implemented in advance, by taking the aluminium base with alumina layer as an example, hydration sealing of hole processing procedure and curable materials sealing of hole processing procedure is generally comprised.Aluminium base need to be put into hot water by hydration sealing pores, typically about Celsius more than 90 degree, be soaked 30 ~ 60 minutes, alumina layer and water is generated aqueous alumina to be closed hole and form sealing of hole layer, its wearability is improved whereby.It is curable Material sealing of hole processing procedure is generally coating resin or melting paraffin wax and is subject to consolidate into sealing of hole layer firmly after hole to seal.But, alumina layer after such a sealing pores is when subsequently carrying out high temperature process, the stress that is easy to because of moisture evaporation or caused by sealing of hole layer, the coefficient of expansion difference between aluminium base and alumina layer and rupture alumina layer, crack 5 as shown in Figure 1 C, thus there may be leakage path.To avoid said circumstances, as shown in figure iD, formed in the present embodiment with high temperature process before following patterned conductive layer, substrate after this anodization will be without being hydrated sealing of hole processing procedure or curable materials sealing pores, but the bearing substrate is soaked in insulating oil (material as described below), after described hole 4 is covered with thin film of insulating oil 6, the thin film of insulating oil for staying in bearing substrate upper surface is removed again, therefore, before following patterned conductive layer is formed with high temperature process, the upper surface of bearing substrate will be without any sealing of hole layer or thin film of insulating oil, the temperature of above-mentioned insulating oil is from room temperature to 150 degree Celsius, it is general then to be preferred no more than 300 degree.

Patterned conductive layer

Refer to Figure 1A, in this example, a patterned conductive layer 170 is additionally formed on the surface of planarization insulating layer 160 of bearing substrate 102, it includes engagement pad 170a to connect luminescent grain 104 through wire 190, and the part of above-mentioned patterned conductive layer is so-called circuit pattern.In addition, height and engagement pad 170a-cause to make the bottom of luminescent grain 104, also may be selected to form a supporting part 170b to carry luminescent grain 104 on the surface of planarization insulating layer 160.In one embodiment, the mode set luminescent grain 104 of patterned conductive layer 170 is welded on supporting part 170b using Ji Guang Rong.

In the embodiment of fabricating patterned conductive layer, it can select by plating or the metal material of magnetron sputtering one on planarization insulating layer 160, to be used as patterned conductive layer 170.Another way is with photographic printing（Screen print)-conductive ink (conductive ink) is on planarization insulating layer, and then heat cure conductive ink is on planarization insulating layer 160, to be used as patterned conductive layer 170.

Conductive ink can be a thermosetable polymers resin (conductor filled thermosetting polymer resin ink) for being filled with conductive material, disclosed in example mouthful United States Patent (USP) 5859581

4 blunt paste compositions. Another embodiment is to utilize high temperature process, such as 400-600 degree Celsius, solidification silver paste formation includes engagement pad 170a patterned conductive layer, and the supporting part 170b that can be combined closely with luminescent grain,-as silver paste glass dust or resin material can be mixed into improve adherence, preferably, can be used phosphide material combined silver and glass dust as silver paste and carrys out fabricating patterned conductive layer to increase thermal conductivity.

But as discussed previously, when being subsequently formed patterned conductive layer when on substrate 102, it is possible to be destroyed thin metal-insulator Rotating fields because of 400-600 degree high temperature process, and form leakage path, therefore as shown in figure iD, in addition to avoiding carrying out hydration sealing of hole processing procedure or curable materials sealing of hole processing procedure before formation circuit pattern, it is another to may be selected to be soaked in insulating oil once again after high temperature process formation circuit pattern, for example it is soaked in methyl-silicone oil to lower the different stress that metal and metal dielectric layer are produced by high temperature, it can again insert in hole 4 and be insulated simultaneously.

That is, in one embodiment, when with anode processing mode in the surface of aluminium base 102 formed an alumina layer 160;And when printing conductive ink being formed into a patterned conductive layer 170 on the alumina layer 160 in high temperature sintering mode, separately can be when aluminium base 102 be cooled to below 350 degree, it is soaked in insulating oil of the temperature more than 100 degree and lowers the different stress that metal and metal dielectric layer are produced by high temperature, the chance in crack is formed while producing the effect of insulation to reduce.

In one embodiment, because aluminium base aoxidizes alumina layer (such as alundum (Al2O3) of formation because of anode processing before first）May be when subsequently forming 4 blunt slurry conducting wire in alumina layer surface, it could solidify because silver paste needs about 400-600 degrees Celsius, and alumina layer and aluminium base may produce different internal stress after by 400-600 degree high temperature, thus cause alumina layer rupture to cause silver paste to penetrate into, form leakage path.Therefore the one of this example is characterized as that not yet can be put into about 100 degree Celsius before cooling completely in silver paste curing process soaks into 150 degree or so of insulating oil, typically to be preferred no more than 300 degree.Can so be rushed in Slow in the temperature-fall period after hot setting silver paste and lower silver paste, three kinds of different materials of alumina layer and aluminium base different internal stress for producing after by 400-600 degree high temperature, secondly, issuable leakage path can be isolated by the insulating oil for inserting hole, and in one embodiment, above-mentioned temperature-fall period about takes 5-30 minutes or so. In a selectable processing procedure, the thin film of insulating oil for staying in bearing substrate upper surface can be removed again, therefore, in bearing substrate upper surface, the interface particularly between patterned conductive layer and the metal-insulator layer surface will be without any sealing of hole layer or thin film of insulating oil.It is worth noting that, signified sealing of hole layer refers to produce by sealing of hole processing procedure working process herein, and unprovoked natural exposing is produced by external environment.

Heat radiation module

Referring again to Figure 1A, in the present embodiment, the bottom of bearing substrate 102 separately includes a heat-conducting part 180, and it can accommodate one or more heat conducting pipes 112 to export hot-fluid caused by luminescent grain 104.Wherein the surface of heat-conducting part 180 includes one or more grooves 102a to accommodate the heat conducting pipe 112.

In a preferred embodiment, illuminating module 100 is more alternative including a radiating part 114, and it is located at the lower section of bearing substrate 102.Wherein, radiating part 114 can be by the closely sealed heat conducting pipes 112 of corresponding groove 112a and the ο of bearing substrate 102 in figure ia, the lower surface of radiating part 114 may include radiating fin or cellular, cellular ceramic structure 115 to promote radiating effect, wherein when bearing substrate 102 is carbofrax material layer, can altogether it be burnt with cellular, the cellular ceramic heat-dissipating structure of carborundum and integrally formed.

Interface between reflective structure and bearing substrate

Refer to the illuminating module shown in Fig. 2 Α.In the present embodiment, the bottom of reflective structure 110 is engaged on bearing substrate 102 by sticker 150, there is certain height after solidifying yet with sticker 150, therefore, the side light that the side of luminescent grain 104 is sent will likely some can enter interface between reflective structure 110 and bearing substrate 102, no matter therefore sticker is made up of transparent or opaque resin, into this interface light and can not be reflected by reflective structure, it is thus possible to the luminous efficiency of luminous row can be detracted.

In this example, many luminous powders are mixed with sticker 150 such as transparent resin, such as fluorescent material, the side light at the interface so entered between reflective structure 110 and bearing substrate 102, the luminous powder in sticker can be excited again and made lighting and reentering in luminous row, thus improves luminous efficiency. The arrangement of multiple luminescent grains

Refer to the arrangement mode of the luminous row with multiple luminescent grains shown in Fig. 2 B, Conventional luminescent module is to be surrounded with a reflector based on the packing forms of single chip, the reason for not using many chip array modes is that the side of each luminescent grain may each cover the side light that other luminescent grain sides are sent, and because of Er, Minus has damaged luminous efficiency.

In order to improve luminous efficiency, arrangement mode without modular luminescent grain and reflective structure disclosed in the present embodiment can be applied to the illuminating module described in preceding embodiment.

Illuminating module includes multiple luminous row 130a, 130b, and each luminous row are surrounded by a reflective structure 110.By taking luminous row 130b as an example, it includes multiple luminescent grains, and such as luminescent grain 104a, 104b can be carried on substrate 102.This side wall of reflective structure 110 includes a reflecting surface, the light L sent to Refl-Luminous crystal grain.In luminous row 130b, for the relation between adjacent two luminescent grain, such as described luminescent grain 104a, 104b each include at least side 124a, 124b, and wherein luminescent grain such as 104a side 124a perspective plane is substantially not exclusively overlapping with corresponding luminescent grain 104b side 124b.In another embodiment, such as requirement based on higher photoluminescence efficiency, luminescent grain 104a side 124a perspective plane can be substantially completely not overlapping with corresponding luminescent grain 104b side 124b.Separately by taking quadrangle crystal grain as an example, if 4 sides of adjacent two crystal grain are arranged in the above described manner, highest luminous efficiency can be obtained.

In general, substantially not exclusively the overlapping side 124a for referring to luminescent grain 104a perspective plane is less than the 90% of the perspective plane area with corresponding luminescent grain 104b side 124b lap;The substantial not overlapping side 124a for referring to the luminescent grain such as 104a perspective plane is less than the 10% of the perspective plane area with corresponding luminescent grain 104b side 124b lap;If wherein luminescent grain 104a side 124a perspective plane is substantially less than the 50% of the perspective plane area with corresponding luminescent grain 104b side 124b lap, effect is preferable.Best results when lap is substantially zero, are typically then no more than 70%.

In addition, the luminescent grain may be selected to be made up of polygonal luminescent grain, e.g. four sides Shape or hexagon, and this shape is according to depending on crystal grain cutting technique.

Separately for the relation of luminescent grain and reflective structure, in one embodiment, when a luminescent grain has the direct projection light L essence that side the more sent or when not stopped by other luminescent grains, can obtain higher luminous efficiency towards the reflective structure side wall reflective surface with one page oblique angle；When the direct projection light L that all sides of a luminescent grain are sent essence or with an inclination angle when not stopped by other luminescent grains, highest luminous efficiency is can obtain towards the reflective structure side wall reflective surface.However, also can allow direct projection light in part to be stopped by other luminescent grains when the density requirement of luminescent grain is higher, overlapping area definition as discussed previously.

Separately as shown in Figure 2 B, include a most short spacing p between two adjacent luminescent grain 104a and luminescent grain 104b, the e.g. distance of two plates end points, therefore it can adjust most short spacing p distance and make it that the perspective plane A1 and luminescent grain 104a of luminescent grain 104b side edge surfaces side edge surface A2 essence is not overlapping or not exclusively overlapping, for example, lap substantially accounts for perspective plane area below 10%, preferably be zero；Or essentially less than 70%, preferably is less than 50%.In another embodiment, by way of multiple luminescent grains are set with appropriate spacing, direct projection light essence that each side of at least two neighboring dies is sent can be made or with an angle of inclination towards the side wall of reflective structure, and reaches higher luminous efficiency.

In another embodiment, luminescent grain 104a can be set in diamond array mode, in other words, to avoid excessively stopping light because the side projection surface of adjacent two luminescent grain is overlapping, when the luminescent grain is made up of polygonal luminescent grain, because each luminescent grain includes a diagonal extended by two-end-point, therefore the luminescent grain can be formed a line in the way of diagonal is parallel to the side wall of reflective structure 110.For example, multiple luminescent grains can each include a two-end-point being pointed on oblique angle line, and the two-end-point of the luminescent grain is located parallel on the axis of the reflective structure madial wall, or be located parallel to also may be used on the parallel lines of the axis.

In addition in a specific embodiment, for example in quadrangle crystal grain, two sides that luminescent grain 104a is connected can be made to be set in the way of an angle of inclination is towards same reflective structure side wall, can so make the luminescent grain 104a direct projection light for two sides being connected towards same reflective structure Side wall.In addition, when each side of luminescent grain is different in size, then prioritizing selection makes length most long side or therefore the direct projection light with larger light-emitting area directly or with an angle of inclination is set towards reflective structure side wall.

By the arrangement of above-mentioned luminescent grain, the direct projection light that luminescent grain side is sent can be effectively guided, essence and is difficult to be stopped by other luminescent grains towards the side wall reflecting surface of reflective structure, therefore can effective improving luminous efficiency.
