Detailed description of the invention
For making there is further understanding to object of the present invention, structure, feature and function thereof, embodiment is hereby coordinated to be described in detail as follows.
Embodiment as shown in Figure 2 A and 2 B, light-emitting device 800 of the present invention comprises first substrate 100, second substrate 200, a plurality of first color temperature light sources 910 and a plurality of second color temperature light sources 920.There is period 1 property projective structure 710 first side 110 of first substrate 100.There is Secondary periodicity projective structure 720 second side 220 of second substrate 200, first color temperature light sources 910 and the second color temperature light sources 920 are arranged on period 1 property projective structure 710 and Secondary periodicity projective structure 720 respectively, and are arranged in the first pairs of bit line 911 and the second pairs of bit line 922 respectively.Wherein, the first color temperature light sources 910 and the second color temperature light sources 920 is better is respectively the LED light source having the first colour temperature and have the second colour temperature.First colour temperature and the second colour temperature is better falls within cold white color system reference color temperature (5000K ~ 6500K respectively, i.e. general cognitive white light in daytime) and warm white system reference color temperature (2700K ~ 3500K, i.e. general cognitive yellowish-white light), but not as limit, first pairs of bit line 911 and the second pairs of bit line 922 are virtual lines, and the present invention is not also defined as straight line.
Period 1 property projective structure 710 and Secondary periodicity projective structure 720 are can the projective structure of interlaced combination.Specifically, as shown in figs. 2 a and 2b, period 1 property projective structure 710 and Secondary periodicity projective structure 720 are preferably can the finger-shaped edge of interlaced combination, but the present invention is not as limit, in different embodiments, processing procedure difficulty or ease, bond strength, manufacturing cost or the factor such as attractive in appearance can be considered, adopt different designs.Such as but not limited to wave structure as shown in Figure 3A, three-legged structure as shown in Figure 3 B or jigsaw structure as shown in Figure 3 C.Wherein, with the jigsaw structure shown in Fig. 3 C, prevent from because can mutually engage between substrate, have preferably intensity, and the second pairs of bit line 922 after the first pairs of bit line 911, design comparatively can there is flexibility.
Embodiment as shown in Figure 2 A and 2 B, a plurality of first color temperature light sources 910 is arranged on first substrate 100 and is arranged in the first pairs of bit line 911, and the first pairs of bit line 911 is better extends on period 1 property projective structure 710.A plurality of second color temperature light sources 920 is arranged on second substrate 200 and is arranged in the second pairs of bit line 922, and the second pairs of bit line 922 is better extends on Secondary periodicity projective structure 720.Wherein, the first pairs of bit line 911 and the second pairs of bit line 922 are virtual lines, and are not defined as straight line.Embodiment as shown in Figure 2 B, when period 1 property projective structure 710 and Secondary periodicity projective structure 720 staggered in conjunction with time, the spacing of the first pairs of bit line 911 and the second pairs of bit line 922 is not more than preset length d, this preset length d is that the distance value that colour temperature uneven phenomenon is more weak appears in light-emitting device, but the present invention is not specifically limited, this preset length d can be determined according to actual service condition, such as, the mode that the present invention adopts period 1 property projective structure 710 to be combined with Secondary periodicity projective structure 720, this preset length d can be made to be less than the diameter of the first color temperature light sources or the second color temperature light sources.
Furthermore, pre-set dimension d is preferably not more than period 1 property projective structure 710 or Secondary periodicity projective structure 720 other outer ends distance to its root.That is, when period 1 property projective structure 710 and Secondary periodicity projective structure 720 staggered in conjunction with time, the first pairs of bit line 911 and the second pairs of bit line 922 are all positioned between the root of period 1 property projective structure 710 and the root of Secondary periodicity projective structure 720.Wherein, in preferred embodiment as shown in Figure 4, when Secondary periodicity projective structure 720 and period 1 property projective structure 710 staggered in conjunction with time, the first pairs of bit line 911 and the second pairs of bit line 922 can coincide with one another, that is now preset length d equals zero.In other words, the first color temperature light sources 910 and the second color temperature light sources 920 arrange along same pair of bit lines.
To sum up, due to light-emitting device 800 of the present invention period 1 property projective structure 710 and Secondary periodicity projective structure 720 staggered in conjunction with time, the spacing of its first pairs of bit line 911 and the second pairs of bit line 922 is less than preset length d, that is the distance side by side between a plurality of first color temperature light sources 910 along the first pairs of bit line 911 spread configuration and a plurality of second color temperature light sources 920 along the second pairs of bit line 922 spread configuration is less than preset length d, therefore (be such as less than the distance of outer end to its root of periodically projective structure when preset length d is less, even equal zero), a plurality of first color temperature light sources 910 can be considered in fact along identical pairs of bit line spread configuration with a plurality of second color temperature light sources 920, jointly to be formed the line source of even light mixing.By this, light-emitting device 800 of the present invention can send the more uniform light of colour temperature, and the different distribution of light sources of Yin Sewen can be avoided in different pairs of bit line cause the phenomenon of light source both sides colour temperature inequality.
Further, if the light that light-emitting device sends could must be obtained by the first color temperature light sources and the 3rd color temperature light sources mixed light being different from the second color temperature light sources in addition, now only need replace second substrate with the 3rd substrate being provided with the 3rd color temperature light sources, original first substrate still can be continued to employ.Not only escapable cost, also can increase use flexibility.On the other hand, the first substrate 100 of light-emitting device 800 of the present invention can combine with Secondary periodicity projective structure 720 is staggered by period 1 property projective structure 710 with second substrate 200, in other words, when first substrate 100 combines with second substrate 200, section structure is had to stretch into the other side respectively.By this, can save required space is set.
In the such as embodiment shown in Fig. 2 A to Fig. 4, first substrate 100 and second substrate 200 are respectively strip, and first substrate 100 is arranged in parallel with second substrate 200.But in different embodiments, first substrate 100 and second substrate 200 are not limited to strip, are also not limited to arranged in parallel.Such as in the different embodiments shown in Fig. 5, first substrate 100 is around second substrate 200, and the radius of first substrate 100 is greater than the radius of second substrate 200.Wherein, the first side 110 surrounds inner space 400 in the inside of first substrate 100, and second substrate 200 can embed inner space 400, and a plurality of Secondary periodicity projective structure 720 is combined with a plurality of period 1 property projective structure 710 is staggered.Specifically, first substrate 100 is loop configuration, and second substrate 200 can be embedded in the class asterism shape structure of first substrate 100.When second substrate 200 is embedded in first substrate 100, the spacing of the first pairs of bit line 911 and the second pairs of bit line 922 is less than preset length d.By this, a plurality of first color temperature light sources 910 can be considered in fact along identical pairs of bit line spread configuration with a plurality of second color temperature light sources 920, jointly to be formed the toroid light source of even light mixing, now, the first pairs of bit line 911 and the second pairs of bit line 922 are ringed line.
Different embodiments as shown in Figure 6, there are third periodic projective structure 730, the 3rd substrate 300, a plurality of 3rd color temperature light sources 930 and a plurality of 4th color temperature light sources 940 in the 3rd side 130 that light-emitting device 800 more comprises first substrate 100, and this first color temperature light sources 910, second color temperature light sources 920, the 3rd color temperature light sources 930 and the 4th color temperature light sources 940 are respectively the light source assembly of colour temperature different from each other.There is period 4 property projective structure 740 4th side 340 of the 3rd substrate 300.A plurality of 3rd color temperature light sources 930 is arranged on the third periodic projective structure 730 of first substrate 100, is arranged in the 3rd pairs of bit line 933, and the 3rd pairs of bit line 933 is better extends on third periodic projective structure 730.A plurality of 4th color temperature light sources 940 is arranged on the period 4 property projective structure 740 of the 3rd substrate 300, is arranged in the 4th pairs of bit line 944, and the 4th pairs of bit line 944 is better extends on period 4 property projective structure 740.When third periodic projective structure 730 and period 4 property projective structure 740 staggered in conjunction with time, the spacing of the 3rd pairs of bit line 933 and the 4th pairs of bit line 944 is less than preset length d.When period 4 property projective structure 740 and third periodic projective structure 730 staggered in conjunction with time, the 3rd pairs of bit line 933 and the 4th pairs of bit line 944 can coincide with one another further.
Specifically, first substrate 100 by the periodicity projective structure being arranged on relative two sides, can combine with the periodicity projective structure of another substrate is staggered respectively.By this, the extendibility of light-emitting device 800 of the present invention can be increased, also by increase number of substrates, number of light sources and light source kind can be increased.Identical concept can be applicable to aforementioned toroidal substrate, and such as, in the different embodiments shown in Fig. 7, the 3rd substrate 300 is around first substrate 100, and the radius of the 3rd substrate 300 is greater than first substrate 100.When first substrate 100 is embedded in the 3rd substrate 300, the spacing of the 3rd pairs of bit line 933 and the 4th pairs of bit line 944 is less than preset length d.By this, a plurality of 3rd color temperature light sources 930 can be considered in fact along identical pairs of bit line spread configuration with a plurality of 4th color temperature light sources 940, jointly to be formed the toroid light source of even light mixing.
Embodiment as shown in Figure 8, light-emitting device 800 comprises the first control unit 610 and the second control unit 620 further.First control unit 610 couples, for controlling the luminous intensity of a plurality of first color temperature light sources 910 with a plurality of first color temperature light sources 910.Second control unit 620 couples, for controlling the luminous intensity of a plurality of second color temperature light sources 920 with a plurality of second color temperature light sources 920.Wherein, the first control unit 610 or the second control unit 620 are optionally controlled, in order to export the luminous intensity of different weight percentage.In other words, first substrate 100 and second substrate 200 respectively with the first control unit 610 and the second control unit 620, the luminous intensity using the first color temperature light sources 910 making to be located on first substrate 100 and the second color temperature light sources 920 be located on second substrate 200 is respectively by the first control unit 610 and the second control unit 620 is independent controls.Therefore, as the colour temperature for changing light-emitting device 800 emitted light, the luminous intensity only changing the first color temperature light sources 910 can be selected, or only change the luminous intensity of the second color temperature light sources 920, or change the luminous intensity of the first color temperature light sources 910 and the second color temperature light sources 920 simultaneously, use the colour temperature controlling light-emitting device 800 emitted light more expediently.
Embodiment schematic diagram as shown in Figure 9, light-emitting device 800 comprises control unit 600 further, and control unit 600 comprises output control circuit 601, first circuit 611 and second circuit 622.Output control circuit 601 stores the parameter value of the output percentage of plural groups first color temperature light sources and the second color temperature light sources luminous intensity.First circuit 611 couples with output control circuit 601 and a plurality of first color temperature light sources 910 respectively.Second circuit 622 couples with output control circuit 601 and a plurality of second color temperature light sources 920 respectively.Wherein, output control circuit 601 according to parameter value, the luminous intensity of the multiple percentage combination of the output of Programmed control to the first circuit 611 and second circuit 622.Specifically, the parameter value that output control circuit 601 stores can such as following table 1:
Table 1: the parameter value that output control circuit stores
For the first color temperature light sources 910 and the second color temperature light sources 920 is respectively cold, light source in warm color, as made the colder colour system of colour temperature of light-emitting device 800 emitted light, the parameter value that output control circuit 601 adopts parameter one or parameter two can be set; As made the inclined warm colour system of the colour temperature of light-emitting device 800 emitted light, the parameter value that output control circuit 601 adopts parameter four or parameter five can be set.By this, can be convenient and control the colour temperature of light-emitting device 800 emitted light rapidly.
