The the first filament branch road formed by least one the first filament is comprised according to LED of the present utility model, and the second filament branch road formed by least one second filament.First filament and the second filament are formed by LED chip string respectively.The LED chip string forming the first filament and the second filament can have the connected mode of the LED chip of various mode, such as the combination etc. of series connection, series and parallel connections.The syndeton forming the LED chip string of the first filament can be identical or different with the syndeton of the LED chip string forming the second filament, also can comprise the LED chip of identical or different quantity.First filament and the second filament can be formed as elongated strip to simulate the tungsten filament for conventional incandescent as line source, also can form the various shape such as spirality, W shape.
LED chip string for the first filament and the LED chip string for the second filament are capped with different light-converting materials, such as different phosphorescence silicon coatings.The light that LED chip sends can be converted to the light with specific colour temperature by different light-converting materials.By providing different light-converting material coatings to the first filament and the second filament, make the first filament and the second filament can launch the light with the first colour temperature and the second colour temperature respectively, wherein, the first colour temperature is different with the second colour temperature.
General principle of the present utility model is, although the colour temperature of the light obtained by often kind of light-converting material is uncontrollable, by the mixed proportion regulating two or more to have the light of different-colour, can obtain the continuous adjustment of the colour temperature to mixed light.The ratio of this pigment be similar to by regulating different colours obtains new color.
In order to enable the light of the first colour temperature sent by the first filament in the first filament branch road regulate with the ratio of the light of the second colour temperature sent by the second filament in the second filament branch road, wish the light intensity that can regulate the luminescence of the first filament and the second filament individually or associatedly.Because LED chip normally works usually under rated voltage, therefore its luminous intensity can be regulated by regulating the size of current of the LED chip be supplied in the first filament and the second filament.
In order to regulate arbitrarily the electric current through the first filament and the second filament, the mode of most convenient be make the first filament branch road and the second filament branch road completely independent from one another.Like this, by respectively the first filament branch road being connected to different drivers from the second filament branch road, and by controlling this two drivers respectively, the first filament branch road and the second filament branch road can be made to obtain arbitrary size of current ratio, to obtain the continuous adjustment of the colour temperature to mixed light.
And in order to save cost and space, can only provide a driver to control the first filament branch road and the second filament branch road simultaneously, make to be changed to some extent by the size of current of the first filament branch road and the second filament branch road, also obtain continuous print to make the ratio of electric current to regulate, thus obtain the continuous adjustment to the colour temperature of mixed light.In this case, first filament branch road and the second filament branch road can share one end (such as first end) or a pole to be connected to the first pin in the pin 8 of driver, and the other end (such as the second end) of the first filament branch road and the second filament branch road is then connected respectively to the second pin in driver pin 8 and the 3rd pin independently of one another.Certainly, the two ends of the first filament branch road and the second filament branch road also can be independent of each other.
As shown in Figure 1, according in an embodiment of the present utility model, the column 2 that LED comprises supporting member 1 and extends from supporting member 1 along the longitudinal axis.First electrode retaining collar is arranged on the far-end (one end away from supporting member 1) of column 2, and comprises the inner ring 31 and outer shroud 32 that are directly electrically connected each other by connector 33, and its outer-loop 32 is arranged around inner ring 31.Second electrode retaining collar 4 and the 3rd electrode retaining collar 5 are arranged on the near-end (one end near supporting member 1) of column 2, and the 3rd electrode retaining collar 5 is arranged around the second electrode retaining collar 4.First electrode retaining collar 3, second electrode retaining collar 4 and the 3rd electrode retaining collar 5 are fixed on column 2 or supporting member 1 insulated from each otherly, and are electrically connected on three pins 8 being formed in supporting member 1 respectively, for receiving three controlled signal respectively.These three pins 8 can be connected on two outer electrodes of lamp by other electronic devices (such as power line carrier module and wireless control module) in lamp.These two outer electrodes are used for being electrically connected with two electrodes in the lamp socket installing this lamp with the power supply received from civil power.The signal of telecommunication from these two outer electrodes is changed into the three road controlled electrical signal being respectively used to these three pins 8 by the electronic device of such as power line carrier module and wireless control module in lamp, to control the electric current by the first filament branch road and the second filament branch road respectively.
First filament branch road comprises the multiple first filament strings 6 (being 3 the first filament strings 6 in Fig. 1) be connected in parallel between its first end and the second end.The first end of each first filament string 6 is electrically connected to the inner ring 31 of the first electrode retaining collar, and the second end of each first filament string 6 is electrically connected to the second electrode retaining collar 4.Second filament branch road comprises the multiple second filament strings 7 (being 6 the second filament strings 7 in Fig. 1) be connected in parallel between its first end and the second end.The first end of each second filament string 7 is electrically connected to the outer shroud 32 of the first electrode retaining collar, and the second end of each second filament string 7 is electrically connected to the 3rd electrode retaining collar 5.Like this, the first filament string 6 is arranged on inner ring around column 2, and the second filament string 7 is arranged on outer ring around the first filament string 6.Advantageously, the first filament string 6 and the second filament string 7 are arranged evenly and at intervals around column 2 respectively, circumferentially to provide basic uniform Light distribation around the whole of column 2.The quantity of the first filament string 6 and the quantity of the second filament string 7 can be individual arbitrarily, and the two can be identical or different.
In the embodiment shown in Fig. 1, the diameter of the second electrode retaining collar 4 is greater than the diameter of the inner ring 31 of the first electrode retaining collar, and the diameter of the 3rd electrode retaining collar 5 is greater than the diameter of the outer shroud 32 of the first electrode retaining collar, the first filament string 6 and the second filament string 7 is made to be arranged as the truncated cone-shaped extended along column respectively.Like this, can obtain the Light distribation more concentrated than near-end at the far-end of column 2 (i.e. the far-end of lamp), this is conducive to obtaining the light distribution basically identical with the axis of column 2 at the far-end of lamp.But this not necessarily.The diameter of the first electrode retaining collar, the second electrode retaining collar 4 and the 3rd electrode retaining collar 5 can be arranged arbitrarily, and the first filament string 6 and the second filament string 7 can be parallel from column 2 or become any space angle to extend and with different shapes around column 2, and the first filament string 6 and the second filament string 7 also can distribute around column 2 with uneven arbitrary form.Thus, the first filament string 6 and the second filament string 7 can form various shape around column 2.
Like this, because the first filament string 6 is electrically connected to inner ring 31, and the second filament string 7 is electrically connected to outer shroud 32, and inner ring 31 and outer shroud 32 are electrically connected to each other by connector 33 and form equipotential first electrode retaining collar, one end of being connected with the common electrical of the second filament string 7 as the first filament string 6 of this first electrode retaining collar thus, and the first pin 8 be drawn out in supporting member 1 by the first electrode retaining collar is connected to driver using as the public electrode being used for the first filament string 6 and the second filament string 7.Certainly, the first electrode retaining collar also only can arrange a ring, and one end of the first filament string 6 and the second filament string 7 can all be connected on same ring, and this can make the first electrode retaining collar as the public connecting end of the first filament string 6 and the second filament string 7 equally.And the second electrode retaining collar 4 and the 3rd electrode retaining collar 5 are electrically connected the other end of the first filament string 6 and the second filament string 7 respectively, and be spaced apart from each other between the second electrode retaining collar 4 and the 3rd electrode retaining collar 5 and insulate, thus, the second pin on supporting member 1 is drawn out to by the second electrode retaining collar 4 and the 3rd electrode retaining collar 5 and the 3rd pin can be connected to driver as the electrode being respectively used to the first filament string 6 and the second filament string 7.By above structure, achieve the first filament string 6 being connected in parallel (i.e. the first filament branch road) between first pin and the second pin of lamp, and the second filament string 7 being connected in parallel (i.e. the second filament branch road) between first pin and the 3rd pin of lamp.
First electrode retaining collar, the second electrode retaining collar 4 and the 3rd electrode retaining collar 5 can be made up of various conductive material.In one embodiment, the first electrode retaining collar, the second electrode retaining collar 4 and the 3rd electrode retaining collar 5 are formed by copper wire.In an alternative embodiment, the first electrode retaining collar, the second electrode retaining collar 4 and the 3rd electrode retaining collar 5 are sheet metal component.Sheet metal component is easy to manufacture, and has higher mechanical strength.Like this, when each filament is series-connected on each electrode retaining collar, not easily produce due to the connection by filament string between each electrode retaining collar stressed and cause distortion.
Each first filament string 6 can form to launch the light with the first colour temperature by single the first filament as described above, and each second filament string 7 can form to launch the light with the second colour temperature by single the second filament as described above.But, as an alternative, each first filament string 6 or the second filament string 7 can have more complicated structure, such as, any series and parallel structure of multiple first filament can be comprised in first filament string 6, and any series and parallel structure of multiple second filament in the second filament string 7, can be comprised.Multiple filament parts in each filament string not only contribute to the luminous intensity improving each filament string, also obtain different impedances by the different series parallel structure of the filament of varying number, to be conducive to obtaining the pressure drop different from the second filament branch road two ends at the first filament branch road two ends simultaneously.For the same driver control two-way filament branch road of use, to obtain the adjustment of the ratio of the electric current by two-way branch road be important for this, because thus these two branch roads exist coupling on circuit owing to sharing a pole and being jointly connected to same driver.These two branch roads must have different impedances or pressure drop to obtain different curent change degree.But, must ensure can only there is the first filament in the first filament string 6, and the second filament can only be there is in the second filament string 7.
The structure of lamp described above also may be used for the situation that the first filament branch road and the second filament branch road individually control.In this case, inner ring 31 and the outer shroud 32 of the first electrode retaining collar are not electrically connected each other, thus individually for the first filament string 6 and the second filament string 7, and inner ring 31 and outer shroud 32 are by the different pin of two of being electrically connected to respectively in supporting member 1.Like this, four pins will be formed in supporting member 1.
Fig. 2 shows the composite LED filament 9 that can be used in the LED of Fig. 1.In this composite LED filament 9, same transparency carrier 90 is furnished with two string LED chip, i.e. the first LED chip string 91 and the second LED chip string 92.In the embodiment shown in figure 2, the first LED chip string 91 has 5 LED chip of mutually connecting, and the second LED chip string 92 has 3 LED chip of mutually connecting.But be to be understood that, first LED chip string 91 and the second LED chip string can have the LED chip of any amount, and any series and parallel combination of LED chip, and the quantity of LED chip in the first LED chip string 91 and the second LED chip string can be identical or different.
The first end of the first LED chip string 91 and the first end of the second LED chip string form shared the second end of the first electrode 94, first LED chip string 91 and the second end of the second LED chip string 92 forms the second electrode 95 and the 3rd electrode 96 respectively.Thus, the first LED chip string 91 and the second LED chip string 92 structure to aforementioned in the first filament string 6 similar with the structure of the second filament string 7.Certainly, the two ends of the first LED chip string 91 and the second LED chip string also can be made all independent of one another and form totally four electrodes.Like this, the respective electrode at the two ends of two chip strings is connected respectively by different drivers to carry out independent control to two chip strings.
As shown in Figure 3, the first LED chip string 91 is coated with the first cover 97, the second LED chip string 92 is coated with the second cover 98.First cover 97 and the second cover 98 are at least partial light permeability, and have the first light-converting material coating and the second light-converting material coating respectively in the inner side of the first cover 97 and the second cover 98.This first light-converting material coating is suitable for the light sent by the first LED chip string 91 to be converted to the light with the first colour temperature, and this second light-converting material coating is suitable for the light sent by the second LED chip string 92 to be converted to the light with the second colour temperature, wherein the first colour temperature is different from the second colour temperature.This first light-converting material and the second light-converting material are such as the phosphorescence silicon coatings with different light conversion characteristics.
By three pins of three electrodes 94,95,96 on above composite LED filament 9 respectively at driver are connected, namely by the ratio of driver control by the electric current of the first LED chip string 91 in composite LED filament 9 and the second LED chip string 92, thus the ratio of the intensity of the light of the first colour temperature regulating composite LED filament 9 to produce and the light of the second colour temperature, and then the colour temperature of the light of the mixing of the generation of adjustment composite LED filament 9.
This composite LED filament 9 is arranged on same substrate to form an overall filament part due to the device next-door neighbour of the light by generation two kinds of colour temperatures, therefore, distance between the light of the two kinds of colour temperatures produced is very near, it is mixed with each other immediately after light source sends, more uniform light mixed effect can be obtained thus, make the colour temperature of mixed light more consistent.
Certainly, the same transparency carrier 90 of this composite LED filament 9 also can be arranged the LED chip more than two strings, and for often going here and there the light-converting material coating that LED chip provides different.Like this, the mixing of the arbitrary proportion of the light more than two kinds of colour temperatures can be realized.
In another embodiment, the colour temperature of each self issued light of string LED chip in this composite LED filament 9 is not identical, namely respectively goes here and there between LED chip differing from each other.But, identical light conversion material layer is covered to each string LED chip.Like this, the colour temperature of the light self sent due to each string LED chip is just not identical, and the colour temperature of the light that the light that each string LED sends produces after the conversion through identical light-converting material is still not identical yet.This equally can by the object regulating the light intensity of each string LED chip to reach the mixed proportion of the light regulating each colour temperature thus the colour temperature of adjustment mixed light.
This composite LED filament 9 may be used in LED described above as shown in Figure 1, to replace the first filament string 6 and the second filament string 7 arranged separately.Wherein, first electrode 94 of composite LED filament 9 is electrically connected to inner ring 31 or the outer shroud 32 of the first electrode retaining collar, second electrode 95 is connected to one in the second electrode retaining collar 4 and the 3rd electrode retaining collar 5, and the 3rd electrode 96 is connected to another in the second electrode retaining collar 4 and the 3rd electrode retaining collar 5.Multiple composite LED filament 9 can be so set.Like this, the parallel connection of multiple composite LED filament 9 is connected electrically in the first electrode retaining collar, between the second electrode retaining collar 4 and the 3rd electrode retaining collar 5, wherein the first LED chip string 91 of each composite LED filament 9 is as the first filament or the second filament, and the second LED chip string 92 of each composite LED filament 9 is as the second filament or the second filament, obtain the first filament branch be made up of the first filament and the second filament branch be made up of the second filament thus.
When using composite LED filament 9, only need to provide the circle filament around column 2 can realize the continuous adjustment with the colour temperature of mixed light that is uniformly distributed of mixed light.Meanwhile, the first electrode retaining collar also only needs to arrange a ring.
The combination of the filament of use two kinds of different-colours is all only described in above embodiment.In theory, by suitably regulating the ratio of the electric current of these two kinds of filaments, just can regulate continuously the colour temperature of the mixed light obtained after the mixing of the light of the different-colour of these two kinds of filaments.But be to be understood that, the alight silk with different-colour more than two kinds is provided in LED, or provide the composite LED filament can launched more than the different-colour of two kinds to be also feasible, and scope of the present utility model is intended to contain all these embodiments.In addition, although only provide two filament branch roads in above embodiment in LED, i.e. two circle filament strings (circle first filament string 6 and a circle second filament string 7), but be to be understood that, also can provide more filament branch road for LED, namely the different filament of more multi-turn number is provided.Further, more than one filament also can with arbitrary arranged in form in LED, as long as the filament of identical type pin is electrically connected to identical electrode retaining collar.And the position of the first electrode retaining collar also can be exchanged with the second electrode retaining collar and the 3rd electrode retaining collar.Further, the first electrode retaining collar, the second electrode retaining collar and the 3rd electrode retaining collar also need not be circular, and can be arbitrary shape.
