The specific embodiment
Please refer to Figure 1A, it illustrates the outside drawing according to the light-emitting device of the adjustable color temperature of one embodiment of the invention.The light-emitting device 100 of adjustable color temperature comprises substrate 110, pliability flourescent sheet 120, telescoping mechanism 130 and at least one light source 140.
By extension and the condensation of telescoping mechanism 130, can change the opening angle A1 of pliability flourescent sheet 120, to adjust the colour temperature via the light of pliability flourescent sheet 120 bright dippings.Below further introduce the thin portion structure of the light-emitting device 100 of adjustable color temperature.
Please refer to Figure 1B, it illustrates in Figure 1A the cutaway view along direction 1B-1B '.Pliability flourescent sheet 120 comprises several sub-flourescent sheets 121, and each sub-flourescent sheet 121 is (Figure 1A) ringwise.Adjacent two sub-flourescent sheets 121 connect bendablely, and for example, the thickness of pliability flourescent sheet 120 can make pliability flourescent sheet 120 possess pliability between 0.05 millimeter (mm) and 0.15mm, and under this design, this little flourescent sheet 121 can be integrally formed; Or, although figure does not illustrate, between adjacent two sub-flourescent sheets 121, can adopt column joint, spherojoint or other suitable joint pivot, make pliability flourescent sheet 120 possess pliability.In the extension and condensation course of telescoping mechanism 130, the included angle A 2 of adjacent two sub-flourescent sheets 121 can change between in 30 to 170 degree.
Adjacent two sub-flourescent sheets 121 are respectively doped with the fluorescent material of different color.For example, sub-flourescent sheet 121 ' is doped with red fluorescence powder, and sub-flourescent sheet 121 ' ' doped with yellow fluorescent powder.Due to the expanded angle of the pliability flourescent sheet 120 of Figure 1B, make through the light of sub-flourescent sheet 121 ' less, and through sub-flourescent sheet 121 ' ' light more, change thus bright dipping colour temperature.In one embodiment, sub-flourescent sheet 121 ' ' interior doping yellow fluorescent powder, blue light is many through light, and the light of pliability flourescent sheet 120 bright dippings is high color temperature.
In addition, the material of pliability flourescent sheet 120 comprises polymethyl methacrylate (Polymethylmethacrylate, PMMA) or Merlon (Polycarbonate, PC).
These a little first secondary bracing frames 132 are positioned at the upper end of main backstop 131 and use for pliability flourescent sheet 120 laid thereon.The second secondary bracing frame 133 can drive the first secondary bracing frame 132 to change angle, and then orders about pliability flourescent sheet laid thereon 120 its opening angle of change A1.
Each second secondary bracing frame 133 has relative first end 133e1 and the second end 133e2, and each first end 133e1 is connected in main backstop 131 slidably, and each second end 133e2 is articulated in the first corresponding secondary bracing frame 132.In this example, main backstop 131 has at least one chute 1311, and its long axis direction along main backstop 131 extends, and the first end 133e1 of the second secondary bracing frame 133 slides in chute 1311.
One end 135e1 of flexible member 135 connects this little the second secondary bracing frame 133 or adjusters 134, and it is example explanation that this example be take the prominent bar 1341 that connects adjuster 134.The other end 135e2 of flexible member 135 is fixed on main backstop 131, as is fixed on the inwall of main backstop 131.Flexible member 135 is installed into drift under the expanded angle of the pliability flourescent sheet 120 of Figure 1B, makes flexible member 135 from the state deformation of Figure 1B, store an elasticity potential energy.In another example, the length of flexible member 135 can be installed into drift under the expanded angle of the pliability flourescent sheet 120 of Fig. 2 or Fig. 3 (in rear description).In addition, flexible member 135 can be spring or flexible adhesive tape.
At adjuster 134, adjust in the process of angle A 1 of pliability flourescent sheets 120, adjuster 134 drives the second secondary bracing frame 133 motions, and flexible member 135(is connected with the prominent bar 1341 of adjuster 134) deformation and storage elasticity potential energy.When the length of adjuster 134 release flexible members 135, this elasticity potential energy discharges and drives telescoping mechanism 130 to retract, and makes pliability flourescent sheet 120 get back to the expanded angle of Figure 1B.
Please refer to Fig. 2, its pliability flourescent sheet of light-emitting device that illustrates the adjustable color temperature of Figure 1A is converted into the outside drawing of another expanded angle.By up promoting the position of the adjuster 134 to Fig. 2 of Figure 1A, can drive the second secondary bracing frame 133 to remove to promote the first secondary bracing frame 132, and then order about pliability flourescent sheet 120 and be expanded to state as shown in Figure 2, wherein the included angle A 1 of the pliability flourescent sheet 120 of main backstop 131 2 sides in fact 180 degree, so also can be less than or greater than 180 degree.
In one embodiment, main backstop 131 has a perforation 1312, adjuster 134 also comprises a trip 150, its can be via perforation 1312 draw-in groove 1343 of the prominent bar 1341 of fixed adjuster 134, be used for fixing adjuster 134, avoid the stored elasticity potential energy of flexible member 135 to discharge and pliability flourescent sheet 120 is retracted to the expanded angle of Figure 1B.
In this example, due to the expanded angle A1 of the pliability flourescent sheet 120 of Fig. 2, make through the light of sub-flourescent sheet 121 ' and through sub-flourescent sheet 121 ' ' light quantity identical haply, can obtain an expection colour temperature between the coloured light of 3300K to 5300K, as cold white light.Yet, under the kind and ratio of fluorescent material of adjusting sub-flourescent sheet 121, can obtain cold white light coloured light in addition.
Please refer to Fig. 3, its pliability flourescent sheet of light-emitting device that illustrates the adjustable color temperature of Fig. 2 is converted into the outside drawing of another expanded angle.By up promoting the position of the adjuster 134 to Fig. 3 of Fig. 2, can drive the second secondary bracing frame 133 to remove to promote the first secondary bracing frame 132, and then order about pliability flourescent sheet 120 and be expanded to state as shown in Figure 3, wherein the included angle A 1 of the pliability flourescent sheet 120 of main backstop 131 2 sides surpasses 180 degree.
In this example, the expanded angle A1 due to the pliability flourescent sheet 120 of Fig. 2, makes through sub-flourescent sheet 121 ' ' light less, and more through the light of sub-flourescent sheet 121 ', change thus bright dipping colour temperature.
In addition, light source 140 is for example blue light-emitting diode or ultraviolet light-emitting diodes, and it is located on substrate 110, in order to emission of light via 120 bright dippings of pliability flourescent sheet.The kind of light source 140 is not limit by the present embodiment, and its bright dipping is photochromic can mate with the wavelength conversion characteristics of pliability flourescent sheet 120, to obtain the photochromic of expection, as white light or other coloured light.In this example, several light sources 140 are around the main backstop 131 of telescoping mechanism 130.
Please refer to Fig. 4, it illustrates the cutaway view according to the pliability flourescent sheet of the light-emitting device of the adjustable color temperature of another embodiment of the present invention.Pliability flourescent sheet 220 comprises slide 223 and flourescent sheet 224, and wherein the material of slide 223 comprises polymethyl methacrylate or Merlon, and flourescent sheet 224 covers the outer surface 223s of slide 223.The wavelength conversion characteristics of flourescent sheet 224 can be similar to pliability flourescent sheet 120.
In sum, though in conjunction with above embodiment, disclosed the present invention, it is not in order to limit the present invention.Be familiar with in the technical field of the invention this operator, without departing from the spirit and scope of the present invention, can be used for a variety of modifications and variations.Therefore, protection scope of the present invention should with enclose claim was defined is as the criterion.
