Other objects, features and advantages of the present invention will become apparent upon inspection of the detailed description of the preferred embodiments herein below taken in conjunction with the drawings figures.
The present projecting kaleidoscope may be equipped with a power supply to provide power for rotation or other functions. The power may be wired or wireless supplied for the projecting kaleidoscope from an exterior power source. In the case of wired power supply, the projecting kaleidoscope may include one or more USB ports, direct current ports or alternative current ports. Alternatively, the power supply may be a primary or secondary battery deposited within the projecting kaleidoscope, such as one or more dry cells or rechargeable battery. An exemplary wireless power supply, not limited to, such as inductive power or magnetic power supply.
Next, in the first embodiment, a projecting assembly 30 is positioned between the main body 12 and the assembly of reflector and/or refractor optics 50. The exemplary projecting assembly 30 includes a rotating member 32, a diffuser 34, a pattern plate 36, a translucent film 38 and a base plate 40. Furthermore, the diffuser 34, a pattern plate 36, the translucent film 38 and the base plate 40 are positioned within the rotating member 32. Their combination will be illustrated later. Next, the rotating member 32 may be sleeved onto the sleeve part 125 of the first end 121 of the main body 12.
Next, a light source 14 is positioned within the main body 12. The exemplary light source 14 may include a light emitting diode and the circuit associated therewith. A reflective cup 16 may be located around the light emitting diode. Light derived from the light source 14 irradiates out of the projecting kaleidoscope 2 from the assembly of reflector and/or refractor optics 50 and the lens 54, after passing through the diffuser 34, the pattern plate 36 and the assembly of reflector and/or refractor optics 50 and the lens 54 in sequence. In the case of the projecting kaleidoscope 2 equipped with the light source 14, the main body 12 may includes a power switch 18 and other controls for the control of the light source 14. Next, the main body 12 further includes a base 19 for loading the light source 14. The first end 121 of the main body 12 may include a suitable structure capable of matching and fixing with the second end 523 of the barrel 52.
Further, the translucent film 38 may have a pattern distributed the whole or partial thereon. Thus, a pattern combination of the translucent film 38 and the pattern plate 36 may be acquired, and more different patterns may be acquired by the relative movement of the translucent film 38 and the pattern plate 36 in rotation. In the first embodiment, both of the translucent film 38 and the pattern plate 36 are circular positive pattern film, and the size of the translucent film 38 is bigger than the one of the pattern plate 36, but not limited to. When the rotating member 32 is rotated, the translucent film 38 fixed to the rotating member 32 may be consistent with the rotating member 32, but the movement of the pattern plate 36 may be not consistent with the rotating member 32 because of its smaller size within the relative bigger space 325. Accordingly, more and more patterns are acquired and changeable. It is noted that multitudes of the pattern plates 36 may be positioned within the space 325 to achieve the generation of various patterns.
It is understood that the light derived from the light source 14 may irradiate out the projecting kaleidoscope to project the pattern plate 36 to outside, after passing through the diffuser 34, the pattern plate 36 or the translucent film 38. Thus, the diffuser 34, the pattern plate 36 or the translucent film 38 is translucent in the present invention. Next, the diffuser 34 may be located close to the light source 14 to diffuse the light derived from the light source 14 and enhance the light homogeneousness behind the pattern plate 36 and the translucent film 38. Accordingly, the homogeneousness of the light passing through the assembly of reflector and/or refractor optics 50 may be improved compared to a traditional projecting kaleidoscope, especially the brightness homogeneousness among the boundaries or interfaces of a projected pattern. Thus, the pattern projection in good quality is achieved in the present invention. In the first embodiment, the diffuser 34, not limited to, is formed by coating or pressing non-regular structures on a PET translucent base.
It may be acknowledged that the higher brightness of light source would improve the drawbacks of lower brightness among the boundaries or interfaces for a projected kaleidoscope pattern. However, it is not economic for the projecting kaleidoscope to be equipped with a high power light source. Besides, in practice, the lower brightness of the boundaries or interfaces of the pattern may be not efficiently improved by the use of higher power light source. Thus, the use of the diffuser in the present invention may not only save the energy consumption but also improve the quality of the projected pattern. Moreover, the position of the diffuser closest to the light source is advantageous to treat the light homogeneous before the light passes through the pattern plate to efficiently improve the lower brightness among the boundaries or interfaces, when compared to another position for setting the diffuser. Next, the interior space provided by the projecting kaleidoscope is restricted by the size of the projecting kaleidoscope for the user to hold, which also restricts any member or component to be installed within the projecting kaleidoscope as well. However, the addition of a diffuser within the projecting kaleidoscope in the present invention is still advantageous that the positioning of the diffuser and the assembly convenience for the projecting kaleidoscope are considered in the present invention, as well as the quality enhancement of the projected pattern.
Besides, in the restricted space 127 provided by the main body 12, the reflective cup 16 may be installed around the light emitting diode of the light source 14 to increase the light amount passing through the diffuser 34. Next, a power supply member like a primary or secondary battery (not shown) may be deposited within the space 127 for providing the light source 14 with the power.
Next, the electrical assembly 62 includes a driving member 622, a pivoting member 624 and a supporting member 626. The driving member 622, the pivoting member 624 and the portion of the supporting member 626 are positioned within the main body 42, and the supporting member 626 may be matched with the main body 42. The driving member 622, such as a motor, is configured to drive the pivoting member 624 to rotate, and the sidewall 605 of the projecting assembly 60 in touch with the pivoting member 624 is driven to be rotated. Moreover, the projecting assembly 60 of the translucent box is rotatably and detachably mounted on the supporting member 626. The supporting member 626 has hollow portions 621, 623 corresponding to the light source within the main body 42, such that the light derived from the light source within the main body 42 irradiates out of the projecting kaleidoscope after passing through the hollow portion 623, the diffuser (not shown), the pattern plate 66, the hollow portion 621 and the assembly of reflector and/or refractor optics (including the barrel 72) and out from the lens 64 of the assembly of reflector and/or refractor optics.
