In previous illumination devices, a rich illumination effect can be obtained by combining a plurality of light-emitting diodes to emit different colored lights. In the case of such illumination devices, the energization time of the light-emitting diodes that emit a single color of light is controlled to cause the plurality of light-emitting diodes to emit light in turn to achieve the purpose of emitting different colors of light. However, in order to control the energization time of the plurality of light-emitting diodes, a relatively complicated driving circuit needs to be correspondingly designed, which increases the difficulty of designing the lighting device and is disadvantageous for the promotion of the use of the lighting device.

The two ends of the hollow cylindrical profile are respectively an open end 120 and a closed end 122, wherein the closed end 122 is mechanically coupled to an excitation unit 15, such as a motor or a cylinder, and the open end 120 is provided with a cavity 14A. Further, the illuminating device 1 〇〇 further includes two bearings 16 ′ such as 滚 ball bearings to connect the optical component 12 and the transparent carrier 14 ° Please refer to FIG. 3 together when assembling, firstly, the light source module 11 is The open end 120 is placed in the cavity 14A of the transparent carrier I4. The two ends of the circuit board 111 are inserted into the corresponding groove 1420. Thus, the transparent carrier 14 and the light source module 11 integrally and carrying the light source module 11 ' preferably' the light-emitting diode 1 is located on the axis of the optical element 12. Further, two bearings 16 are sleeved on the two ends 120, 122 of the transparent carrier 14 6 201033532, and the transparent carrier 14 and the two bearings 16 are integrally sleeved into the optical component 12, thereby The two bearings 16 mesh with the open end 120 and the closed end 122 of the optical element 12. Thus, the two bearings 16 connect the transparent carrier 14 to the optical component 12, and the transparent carrier 14 is coaxial with the optical component 12. When the transparent carrier 14 is fixed to energize the excitation unit 15, the excitation unit 15 can drive the optical component 12 to rotate around the transparent carrier 14 and the light source module, and the rotation axis thereof is the central axis of the optical component 12. . The light emitted by the LED 112 can be further transmitted to the optical element 12 after passing through the transparent carrier 14. Referring to FIG. 4-6 together, the working principle of the illumination device 100 provided by the present invention is as follows: Chromaticity Diagram (CIE) as shown in FIG. 5, fluorescent powder 121 (such as red, yellow, green firefly) After the light powder absorbs a single color of light of wavelength A, it is excited and emits other color lights of wavelength B. If only a part of the light of the single color light of wavelength A is absorbed by the phosphor powder 121, the wavelength value of the light emitted after the conversion corresponds to one of the lines on the AB line (excluding points A and B). Taking the embodiment as an example, the LED chip 112 emits blue light A having a wavelength of 465 nm. When the excitation unit 15 drives the optical element 12 to rotate in the direction indicated by the arrow S in FIG. 4, the blue light A is irradiated to the transparent region II. Since the light-transmitting region II is doped with the yellow phosphor powder 121, when the yellow phosphor powder 121 completely absorbs the blue light A, it is converted to emit a wavelength of 575 nm 7 201033532 yellow light B. When the yellow phosphor powder 121 only partially absorbs the blue light A, the wavelength of the light emitted after the conversion corresponds to a point on the AB line. It can be understood that when the yellow phosphor powder 121 has a different absorption ratio for the blue light a, the wavelength of light emitted from the optical element 12 is also different. Alternatively, when the chromatic phosphor 121 absorbs only a portion of the blue light a and converts to emit a different color light than the blue light A, the other color light may be mixed with the completely unabsorbed blue light A to form another color light. ❹ Of course, the curved transparent regions I, II, and III may also be doped with a plurality of glazes 121. As shown in FIG. 6, when the curved transparent region π is doped with green and yellow phosphor powder 121, and the blue light a (wavelength is 465 nm) is completely absorbed by the yellow and green phosphor powders 121, respectively. The light emitted after the conversion is yellow light B and green light c (wavelengths of 575 nm and 540 nm, respectively). If the blue light a is only partially absorbed by the yellow and green phosphor powder κι, the wavelength of the light converted by the yellow and green phosphor powder 121 corresponds to the area enclosed by the three points A, B, and C. One of them (not including VIII, 3, (: three points). Further, the ability of the curved transparent regions I, II, III to absorb and convert the single color light A depends on the light transmission region Ιχ π, ΙΠ The distribution density of the medium phosphor powder 121 is stronger when the distribution density of the phosphor powder ι21 is larger, and in the embodiment, in order to cause the illumination device 100 to emit a richer and gradual color light, preferably The phosphor powder 121 doped by each of the curved transparent regions I, II, and III is distributed differently along the circumferential direction of the optical element 12. For example, the yellow fluorescent light doped in the curved transparent region II 8 201033532 The density of the light powder 121 gradually increases in the opposite direction of the arrow S in FIG. 4, and when the optical element 12 is rotated in the direction indicated by the arrow S in FIG. 4, the blue light A sequentially irradiates the doped yellow phosphor powder of the light-transmitting region η. When the concentration of 121 is small and the area where the concentration of yellow fluorescent powder 121 is large The proportion of yellow light in the light emitted by the optical element 12 will gradually increase, thereby causing the light emitted by the illumination device 100 to exhibit a richer and changing color as the optical element 12 rotates. Φ The optical element 12 may also contain only one type The phosphor powder 121 has a different distribution density along the circumferential direction of the optical element 12. The light-emitting diode 111 emits monochromatic light in the green to violet region to excite the phosphor powder 121. In addition, it can be understood that in order to cause the illumination crack 100 to emit a single blue light during the rotation of the optical element 12, the optical element 12 may further include a transparent region completely doped with the phosphor powder 121, or further The transparent region is hollowed out, whereby the optical element 12 is rotated through the crucible, and a single blue light can be completely transmitted. In another embodiment, the red, yellow, and green phosphor powder 121 may not be doped on the optical element 12. And applied to the surface (such as the inner surface or the outer surface) of the curved light-transmissive region I, U, In of the optical element 12 to form a thin film layer. In terms of driving manner, the present embodiment The excitation unit 15 drives the optical element 12 to rotate, and the light source module η and the transparent support frame are fixed, so that the optical element 12 can rotate around the light source module n. It can be understood that the excitation unit 15 can also mechanically connect the transparent support frame 14 The driving support frame 14 drives the light source module 11 to rotate around its axis, and the optical component 12 is fixed differently, so that the illumination device 1 can be made to emit different colors of light. Of course, the optical The rotation of the component 12 can also be achieved by a manual method. The phosphor powder 121 can also be disposed on the optical component 12 by other forms. Referring to FIG. 7, a plurality of grooves 124 are disposed on the surface of the optical component 12. The phosphor powder (not shown in Fig. 7) is mixed with the liquid colloidal crucible and filled in the plurality of grooves 124, and the colloid is further cured by heating or irradiating UV light. Since the phosphor powder is mixed in the liquid gel, the phosphor powder can be prevented from directly contacting the air to cause aging, and the light conversion property of the phosphor powder can be effectively ensured. Of course, the material of the switchable wavelength may also be doped into the optical element 12 by injection molding, and is not limited to the specific embodiment. The lighting device 1 according to the first and second embodiments of the present invention has the advantages of simple structure, and is advantageous for application and promotion. It can be understood that those skilled in the art can make other changes within the spirit of the present invention.
