The specific embodiment
For making that object of the present invention, structure, feature and function thereof are had to further understanding, hereby coordinate embodiment 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 the first color temperature light sources 910 and a plurality of the second color temperature light sources 920.The first side 110 of first substrate 100 has period 1 property projective structure 710.The second side 220 of second substrate 200 has property second round projective structure 720, the first color temperature light sources 910 and the second color temperature light sources 920 are arranged at respectively on period 1 property projective structure 710 and property second round projective structure 720, and are arranged in respectively the first pairs of bit line 911 and the second pairs of bit line 922.Wherein, the better LED light source that there is the first colour temperature and there is the second colour temperature that is respectively of the first color temperature light sources 910 and the second color temperature light sources 920.The first colour temperature and the second colour temperature be better falls within respectively cold white color system reference color temperature (5000K～6500K, i.e. general cognitive white light in daytime) and warm white be reference color temperature (2700K～3500K, i.e. general cognitive yellowish-white light), but not as limit, the 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 property second round projective structure 720 be can interlaced combination projective structure.Particularly, as shown in Fig. 2 A and 2B, period 1 property projective structure 710 and property second round projective structure 720 are preferably finger-shaped edge that can interlaced combination, but the present invention is not as limit, in different embodiment, can consider processing procedure difficulty or ease, bond strength, manufacturing cost or the factor such as attractive in appearance, 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, because can mutually engaging and prevent between substrate, have preferably intensity, and the second pairs of bit line 922 can, after the first pairs of bit line 911, there is flexibility in design.
Embodiment as shown in Figure 2 A and 2 B, a plurality of the first color temperature light sources 910 are arranged on and on first substrate 100, are 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 the second color temperature light sources 920 are arranged on and on second substrate 200, are arranged in the second pairs of bit line 922, and the second pairs of bit line 922 is better extends on property second round 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 property second round 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 weak appears in light-emitting device, but the present invention is not specifically limited, can determine this preset length d according to actual service condition, for example, the present invention adopts the mode of period 1 property projective structure 710 and 720 combinations of property second round projective structure, can make this preset length d 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 720 other outer ends of property second round projective structure distance to its root.That is, when period 1 property projective structure 710 and property second round 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 property second round projective structure 720.Wherein, in preferred embodiment as shown in Figure 4, when property second round 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 overlap each other, 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 are along arranging with pair of bit lines.
To sum up, due to light-emitting device 800 of the present invention period 1 property projective structure 710 and property second round 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 be less than preset length d along a plurality of first color temperature light sources 910 of the first pairs of bit line 911 spread configurations and along the distance side by side between a plurality of second color temperature light sources 920 of the second pairs of bit line 922 spread configurations, therefore for example, when preset length d hour (is less than the outer end of projective structure periodically to the distance of its root, even equal zero), a plurality of the first color temperature light sources 910 can be considered in fact along identical pairs of bit line spread configuration with a plurality of the second color temperature light sources 920, jointly to form 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 can avoid distribution of light sources that Yin Sewen is different to cause the phenomenon of light source both sides colour temperature inequality in different pairs of bit line.
Further, if the light that light-emitting device sends must could be obtained by the first color temperature light sources and the 3rd color temperature light sources mixed light that is different from addition the second color temperature light sources, now only need replace second substrate with the 3rd substrate that is 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 be by period 1 property projective structure 710 and the staggered combination of property second round projective structure 720 with second substrate 200, in other words, in the time that first substrate 100 combines with second substrate 200, there is respectively part-structure body to stretch into the other side.By this, can save required space is set.
In the embodiment as 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 embodiment, first substrate 100 and second substrate 200 are not limited to strip, are also not limited to be arranged in parallel.In routine different embodiment as 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, makes a plurality of property second round projective structures 720 and the staggered combination of a plurality of period 1 property projective structures 710.Particularly, first substrate 100 is loop configuration, and second substrate 200 can be embedded in the class asterism shape structure of first substrate 100.In the time that 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 the first color temperature light sources 910 can be considered in fact along identical pairs of bit line spread configuration with a plurality of the second color temperature light sources 920, jointly to form 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 embodiment as shown in Figure 6, the 3rd side 130 that light-emitting device 800 more comprises first substrate 100 has period 3 property projective structure 730, the 3rd substrate 300, a plurality of the 3rd color temperature light sources 930 and a plurality of the 4th color temperature light sources 940, and this first color temperature light sources 910, the second color temperature light sources 920, the 3rd color temperature light sources 930 and the 4th color temperature light sources 940 are respectively for differing from one another the light source assembly of colour temperature.The 4th side 340 of the 3rd substrate 300 has period 4 property projective structure 740.A plurality of the 3rd color temperature light sources 930 are arranged on the period 3 property projective structure 730 of first substrate 100, are arranged in the 3rd pairs of bit line 933, and the 3rd pairs of bit line 933 is better extends on period 3 property projective structure 730.A plurality of the 4th color temperature light sources 940 are arranged on the period 4 property projective structure 740 of the 3rd substrate 300, are 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 period 3 property 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 period 3 property projective structure 730 staggered in conjunction with time, the 3rd pairs of bit line 933 and the 4th pairs of bit line 944 further can overlap each other.
Particularly, first substrate 100 can be by the periodicity projective structure that is arranged on relative two sides, respectively with the staggered combination of periodicity projective structure of another substrate.By this, the extendibility of light-emitting device 800 of the present invention be can increase, also can, by increasing number of substrates, number of light sources and light source kind be increased.Identical concept can be applicable to aforementioned annular base plate, and for example, in the different embodiment shown in Fig. 7, the 3rd substrate 300 is greater than first substrate 100 around the radius of first substrate 100, the three substrates 300.In the time that 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 the 3rd color temperature light sources 930 can be considered in fact along identical pairs of bit line spread configuration with a plurality of the 4th color temperature light sources 940, jointly to form the toroid light source of even light mixing.
Embodiment as shown in Figure 8, light-emitting device 800 further comprises the first control module 610 and the second control module 620.The first control module 610 couples with a plurality of the first color temperature light sources 910, for controlling the luminous intensity of a plurality of the first color temperature light sources 910.The second control module 620 couples with a plurality of the second color temperature light sources 920, for controlling the luminous intensity of a plurality of the second color temperature light sources 920.Wherein, the first control module 610 or the second control module 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 module 610 and the second control module 620, use the luminous intensity that makes to be located at the first color temperature light sources 910 on first substrate 100 and be located at the second color temperature light sources 920 on second substrate 200 respectively by the first control module 610 and second control module 620 is independent controls.Therefore, as the colour temperature of wish change light-emitting device 800 emitted lights, can select only to change the luminous intensity of the first color temperature light sources 910, 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 of controlling more expediently light-emitting device 800 emitted lights.
