Figure 10 illustrates the light emission spare that comprises prismatic film.
Fig. 1 shows an embodiment of light output arrangement, and it has cylindrical light emission spare 100 and LED lighting means 200.In order to facilitate the possibility that can be installed in the known lamp, the plant bulk among this embodiment is selected as the fluorescent lamp corresponding to T5, also can expect being matched with the size of other gas-discharge lamp.
At this moment, so constitute cylindrical light emission spare 100, that is, inject this cylindrical light from LED lighting means 200 and radiated through a light gasing surface 110 that constitutes by side face 102 zones.Stipulate that preferably light is radiated through the almost whole peripheral surface 102 of light emission spare 100; Like this, almost the light emission characteristic with fluorescent lamp is identical for the spatial light radioactive nature.
On the bottom surface 101 of cylindrical light emission spare 100, so be provided with a plurality of LED lighting means 200 respectively, so that the light of these LED lighting means 200 is injected in the cylindrical light emission spare 100 through the surface 120 that is different from light gasing surface 110.
Except single led,, preferably can be provided with LED group or LED module as LED lighting means 200 in order to improve luminous flux.At this moment, it for example can be the high-capacity LED module with a plurality of LED, but these LED have the radiating light that varies in color in this embodiment and in its relative adjustment aspect luminous flux density separately, thereby for example can make colour temperature match best various application.
Cylindrical light emission spare 100 has complete cylinder in this embodiment and also in following other embodiment that will describe; This cylinder is to be made up of material transparent, said transparent be to the spectral region of part at least of the radiating light of LED lighting means 200.In device, so light is for example injected in the light emission spare 100 through a planar bottom surface 101 of this cylinder according to Fig. 1.
In addition, in an improvement project of the present invention, light emission spare 100 can be used as photoconduction and constitutes.In the embodiment in figure 1, in a pipe, be provided with solid photoconduction, this photoconduction is made up of transparent material (for example PMMA, PC or glass).
Shown photoconduction has light outgoing mechanism 130; Be used for for example realizing light output through whole peripheral surface 102 through be arranged in light emission spare 100 peripheries identically; Here; In an improvement project of the present invention's design, can light outgoing mechanism also be arranged on other element of light emission spare 100 regulation.This is for example illustrated by light emission spare shown in Figure 4 100 once more.Light outgoing mechanism 130 preferably can the symmedian prism structure of type of being, or also can be the structure that plays reflection or scattering process.
In an improvement project of the present invention, also can so constitute light outgoing mechanism 130, that is, the light emission of cylindrical light emission spare 100 can only be realized through a limited angular extensions alpha.So these light outgoing mechanisms 130 preferably can be dispersed on the part corresponding to this angular extensions alpha of side face of cylindrical light emission spare 100, just as this for example also in that kind shown in Fig. 4.
Described device allows to realize distribution of light according to the mode of at least two changes that have nothing to do each other and can slightly do; A light emission spare 100 that also has this architectural feature for example also has been shown in Fig. 2.
In an improvement project of the present invention, can be the waveguide tubulose by the regulation photoconduction.This for example as shown in Figures 2 and 3, here, waveguide is to be used for photodistributed first cylindrical elements in the light emission spare 100 of the Fig. 2 that is made up of two parts.The side face of second cylindrical elements constitutes the light gasing surface 110 of cylindrical light emission spare 100 at this moment.Second cylindrical elements has discoloration coating 140 in this embodiment, and this discoloration coating absorbs the light that is sent by LED lighting means 200 and in the spectrum of the light output that at least partly is different from LED lighting means 200, radiates bright dipping again.For example can stipulate that the light that is sent by LED lighting means 200 is only partly absorbed by discoloration coating 140 to, and other spectral component of the light of LED lighting means 200 is exported outside the cylindrical light emission spare 100 still.Particularly advantageously be, for discoloration coating 140 reciprocations, can use the LED that sends blue light, white light or ultraviolet light.
So the discoloration coating 140 that for example is planar setting also has the scatterer effect because of it with synergistic way (in synergetischer Weise) radiating light at random, scatterer for example also can only work to some part of radiating light as stated.
In another embodiment for example like the light output arrangement of Fig. 5-shown in Figure 7; These LED lighting means 200 pass the opening in the side face 102 of cylindrical light emission spare 100 and so are provided with according to the present invention; Promptly; The light of injecting the inner space of LED lighting means 200 so sees through this light emission spare 100, makes light emit to space outerpace through the side face zone 102 of cylindrical light emission spare 100.
This is stressed that,, never gets rid of the combination of embodiment according to the present invention.
In an improvement project of the present invention's design, the output of the light of 200 pairs of light emission spares 100 of LED lighting means has obtained the support of light incident structure, and this light incident structure example is as also having light expansion effect.
For example, advantageous particularly ground stipulates in the embodiment of Fig. 5, and LED lighting means 200 is arranged on one and staggers in the hole that forms with respect to the main shaft of cylindrical light emission spare 100 vertically, and therefore this hole has the effect of light expansion lens.This expansion effect for example can be so supported, that is, LED lighting means 200 also has the light extension mechanism, and it for example is the form of integrally formed lens piece, preferably by heat cured and preferably constitute based on the synthetic resin of epoxides.Therefore, can realize that classification light mixes, here, the mixed light degree for example can be depending on the LED lighting means to be decided.And, other light regulating and controlling mechanism can advantageously be set in this hole, said other light regulating and controlling mechanism for example plays reflection or also plays the effect of scattering.
In an improvement project of the present invention's design for example as shown in Figure 6, the scattering mechanism or the colour filter mechanism that are matched with the application scenario can be set, to improve the light emission performance.The light gasing surface 110 of for example cylindrical light emission spare 100 can have this mechanism, and this mechanism preferably is arranged on second cylindrical elements.In a preferred implementation of the present invention, advise, with the whole scatterer that is designed to of side face of the cylindrical light emission spare that preferably constitutes by glass.For example can on PCB (printed circuit board (PCB)), become row that a plurality of LED lighting means 200 are set, PCB extends to its opposed faces from the bottom surface of cylindrical light emission spare 100.
Scatterer causes the side face at random radiation of light through light emission spare 100, and this has covered up the basic arrangement form of point source of light, the spatial light output characteristics of therefore having imitateed fluorescent lamp.
In a structure very advantageous embodiments, this can have the LED lighting means 100 of blue radiating light or ultraviolet radiating light and combine to realize as the discoloration coating of scatterer through use.
Effect for the scatterer for example supporting to constitute by glass; Ad hoc proposal is used white, jade-green, that best incorporated is blue and red LED or cold White LED; They also have discoloration coating usually, and at this, it we can say that according to aforesaid way the scatterer effect is also arranged.Therefore, realized such structure through plain mode, its appointment that scattering mechanism is arranged on cylindrical light emission spare 100 is used for the zone of light incident.Best said scattering mechanism or colour filter mechanism and the LED lighting means 200 spaces ground that staggers is also realized on an appointment is used for the surface 120 or 125 of light incident.For example, they can constitute with the film arrangement form with scattering process, perhaps through directly on appointment is used for the surface 120 or 125 of light incident, forming structure.
What also must stress is; For example specify on the surface 120 or 125 that is used for light incident and light gasing surface 110 through scattering mechanism 170 is arranged in; Possible words can facilitate light to mix with synergistic way together with colour filter mechanism, and this has also followed the theory of expansion of classification light and light mixing.When the light conductive performance of cylindrical light emission spare 100 only drew attention conditionally, this had especially played effect.
Layout according to Fig. 6 has shown this situation.This cylindrical light emission spare 100 is the improvement to embodiment shown in Figure 5, and has the hole with respect to the axial dislocation of main shaft of light emission spare 100, and the opening that LED lighting means 200 passes the side face 102 of light emission spare 100 enters into this hole.From now on, the light regulating and controlling mechanism realizes that with the form of taper dispersing element 170 it is arranged on specifies the surface 125 that is used for light incident, opposed with LED lighting means 200.
On the one hand; So constitute these dispersing elements 170; The light that they preferably make the side face 102 towards cylindrical light emission spare 100 of LED lighting means 200 send is bent towards the main shaft of cylindrical light emission spare 100, thereby, prolong the light path in light emission spare 100 and facilitated the light mixing.
In an improvement project of the present invention; Stipulate in order to support this aspect; In less than the scope of 1:2 and be preferably in the diameter of selecting this hole in the scope of 1:2 to 1:6 and the diameter ratio of light emission spare 100; Can general stipulate that perhaps light extension mechanism light steering mechanism or scattering mechanism in other words is provided with according to this distance relation each other.
On the other hand, also to consider backscattering towards the hole.Considering to utilize backscattering to come under the situation of mixed light, this device can be by improvement like this, that is, this hole also has the photoconduction performance that is the waveguide form.These dispersing elements 170 can satisfy from the function of the light outgoing mechanism 130 of waveguide output light subsequently simultaneously.Guide properties for example can be confirmed through the respective coatings in hole; And in order to support guide properties; Preferably can stipulate guide properties prevailingly, the feasible refractive index that constitutes the waveguide material of cylindrical light emission spare is matched with the refractive index of the transparent chips coating (Chipabdeckung) of LED lighting means 100.
For example can stipulate in an improvement project of the present invention that the hole coating realizes that with the form of film or individual tubes particularly advantageous is that individual tubes or film also can irrespectively be provided with the diameter in hole.Thereby, for example can realize such device, it has as the outer scattering pipe of light gasing surface 120 and replaces ground, hole to have the interior pipe that another has guide properties or scatterer performance.So; Layout and quantity by dispersing element 170; Can make light mixing and light distribution be matched with this application scenario specially, manage the interactive priority between dispersing element and the outer tube dispersing element in especially passing through to select, or utilize the priority of the light mixing of guide properties through selection.Certainly; Related device with described match selection possibility is as for example through being designed to waveguide suggestion; Both be not limited to light through the openings in the side face of cylindrical light emission spare 100 102 and the situation of incident also is not limited to the situation of waveguide as photoconduction.
In addition, the present invention is in no way limited to the situation of one or more holes of staggering vertically or pipe.Therefore, for example can in the improvement project of the present invention of the embodiment of Fig. 7, stipulate, at 1mm～6mm, preferably between 2mm～4mm, select the wall thickness of cylindrical light emission spare 100.For this reason, the opening in the side face 102 of cylindrical light emission spare 100 of situation light emission spare 100 passes to(for) LED lighting means 200 also has enough steadiness, and being enough at least, part forms the circular cross section of light emission spare 100 and supports guide properties.But light emission spare preferably has circular cross section along its whole length.Therefore; Realize the device of the output light like this that a kind of cost is very low, it for example utilizes the surface that constitutes as scatterer of the cylindrical light emission spare 100 that can be made up of the glass that is preferably with the scattered light surface texture and combines to pass the LED lighting means 200 of the side face 102 of cylindrical light emission spare 100 with lining up long line.By the respective design of side face 102 thickness, can mix or utilize the light of guide properties progressively to change between mixing at the light that utilizes dispersing element 170.As stated, preferably adopt the LED of light green color or cold white in this embodiment.With discoloration coating in combination, preferably can use blue-light-emitting mechanism or ultraviolet LED lighting means 200 again.
