Embodiment
Below in conjunction with drawings and embodiments, the utility model embodiment is elaborated.
Embodiment mono-
Refer to Figure 1A, Figure 1B and Fig. 1 C, Figure 1A is the vertical view of an embodiment of color block component in the utility model, Figure 1B be in Figure 1A along the cut-open view of section A-A, Fig. 1 C is the back up pad structural representation of the one side of rotation axis dorsad of the color block component housing shown in Figure 1A.Color block component comprises colour wheel 1, shell 2 and the first pugging 3.
Colour wheel 1 comprises the drive unit with rotation axis 4, and is fixed on the optical devices 5 on this rotation axis 4, and this drive unit is used for driving these optical devices 5 to rotate.In the present embodiment, these optical devices 5 comprise the substrate 52 that carries wavelength conversion layer 51, and wherein this substrate 52 is in the form of annular discs, and this wavelength conversion layer 51 is the ring-type concentric with this disk.Wavelength conversion layer 51 comprises material for transformation of wave length, for absorbing a kind of exciting light of color and producing the Stimulated Light of another kind of color.In practice, material for transformation of wave length can be the material that fluorescent powder, quantum dot or fluorescent dye etc. have wavelength conversion capability.Substrate 52 is made by light transmissive material, and a wavelength conversion layer 51 dorsad side of substrate 52 is used for receiving exciting light and in opposite side outgoing Stimulated Light, these Stimulated Light transmission substrate 52 outgoing.
In practice, can also wavelength conversion layer 51 dorsad a side of substrate 52 be provided with transmission exciting light and reflect the optical filter (not shown) of Stimulated Light, to improve the utilization factor of Stimulated Light.This optical filter is also fixed on rotation axis 4, so that rotation axis 4 drives this wavelength conversion layer 51 and optical filter synchronously to rotate.At wavelength conversion layer 51, comprise that at least two sections for the occasion of the material for transformation of wave length of outgoing different colours Stimulated Light, filter area is end to end one to one forms by different section material for transformation of wave length at least two and wavelength conversion layer 51 for this optical filter.
In the present embodiment, because the travel path of exciting light and Stimulated Light lays respectively at the both sides of wavelength conversion layer 51, so light-emitting window 2a and light inlet 2b are located at respectively on shell 2 on two relative with the both sides of wavelength conversion layer 51 respectively faces.
In practice, also the excitation source for generation of exciting light can be positioned in shell 2, on shell 2 without light inlet is set; Or, colour wheel also can be for reflective, be that substrate 52 is reflective substrate, the Stimulated Light that makes wavelength conversion layer 51 outgoing is all from a side outgoing of these wavelength conversion layer 51 back-reflection substrates 52, like this, light inlet on shell 2 and light-emitting window can coincide, and are all positioned in the one side of the light path that is positioned at Stimulated Light outgoing and exciting light incident on shell 2.
To how reducing in the heuristic process of the noise that color block component sends, inventor of the present utility model finds, the high-speed rotation that the noise that color block component sends does not only include due to colour wheel drives near air to form the noise that high velocity air produces, also comprise the noise that Relative Vibration that the vibration producing due to colour wheel high-speed rotation also produces the back up pad of shell causes, and rear portion noise accounts for the major part of noise.Front portion noise can reduce some gully designs of the sealing of colour wheel and outer casing inner wall by shell, and this has been prior art.And reduction to rear portion noise, inventor of the present utility model has done a large amount of trials and design by analysis.Wherein in the conduct vibrations of colour wheel, to the path of back up pad, add a buffer element, to stop the vibration of colour wheel to be delivered in back up pad.Concrete example, is equipped with pilot hole in the rotation axis of colour wheel and back up pad, in this pilot hole, is provided with screw thread.Screw is successively through the pilot hole of pilot hole, rubber ring and the rotation axis of rubber ring, back up pad and tighten, so that by this, both fix.
But experiment discovery, the effect of this kind of method is very faint, and the reduction of noise is very little.By analyzing rear discovery reason, be, for making rotation axis and back up pad mutually stable fixing, screw need be twisted very tightly, to prevent that colour wheel from coming off in the process of rotating, but this also causes between rotation axis and back up pad, deformation to a certain degree has occurred each rubber ring between screw terminal and back up pad, therefore when rotation axis rotates, the buffer action that rubber ring plays is very little, and then the noise reducing is also very little.In like manner, the effect of other noise reductions that play to the method for adding buffer element on the path of back up pad by the conduct vibrations at colour wheel is also very faint.
And in the present embodiment, not to the path of back up pad 21, to add buffer element in the conduct vibrations of colour wheel 1, but in the one side of colour wheel 1, be glued with the first pugging dorsad in back up pad 21, due to the cushion of this first pugging for being made by sound-proof material, at least part of noise that can in the vibration that absorbs back up pad 21, back up pad 21 be produced be reflected back in shell 2, can reduce largely by back up pad 21 and vibrate and the noise that causes.
Because drive unit comprises drive wire, so shell 2 can also comprise an opening (not shown) for this drive wire is stretched out just.In other embodiments, also can customize the drive unit without drive wire, now each drive end of drive unit can be welded in the one side of a PCB, on box, establish an opening, this PCB covers this opening, and at many wires of box outer setting, this wire is electrically connected on each pad of PCB and drive end, thereby the drive wire of drive unit is transferred to the outside of box.
Preferably, the first pugging 3 is close to other positions of removing light-emitting window region in covering back up pad 21, to reduce to a greater degree noise.Certainly, be not provided with in the occasion of light-emitting window in back up pad 21, the first pugging 3 is preferably close to the whole back up pads 21 of covering.
Because the density relationship of pugging arrives the effect of sound insulation, wherein density is larger, and soundproof effect is better.In the present embodiment, the average density of the first pugging is preferably greater than 1.5g/cc, for example silicagel pad.
While being stimulated due to wavelength conversion layer 51, can produce heat, the first pugging is preferably made by Heat Conduction Material, so that shell 2 is dispelled the heat, and heat conduction silica gel pad for example.
In practice, the factors such as the noise content that can reduce according to actual needs, cost and spatial volume decide material, the thickness that the first pugging adopts or number of plies that the first pugging is set etc.Because the first pugging is cushion, in the process of using color block component, easily this cushion is caused to wearing and tearing or other damages, therefore, at the first pugging of color block component dorsad in a side of back up pad, preferably fold and be provided with a cap 6, be used for covering this first pugging 3, to prevent its wearing and tearing.But should be noted, at cap 6 in the one side of the first pugging, this cap 6 is provided with a groove 6a on the region of at least corresponding rotation axis, so that cap 6 is provided with gap between the region of corresponding rotation axis on this cap 6 and the first pugging 3 while covering upper the first pugging 3, and then the vibration of minimizing back up pad is delivered on cap.
As shown in Figures 2 and 3, Fig. 2 is the another kind of structural representation of cap in color block component of the present utility model, and Fig. 3 is along the cut-open view of section B-B in Fig. 2.Preferably, at cap 6 in a side of the first pugging, on the neighboring area around this cap 6, being provided with and comparing other regions 61 is protruding plane 62, when this cap 6 is covered on the first pugging 3, only have this convex plane 62 and the first pugging 3 to be in contact with one another fixing, and all and between the first pugging have certain interval on other regions 61.The vibration that like this, can greatly reduce back up pad is delivered on cap.
At least two pilot hole (not shown) are all set on the neighboring area of cap 6 and back up pad 21, and each pilot hole in back up pad 21 and each pilot hole on cap 6 corresponding one by one.Meanwhile, the position of each pilot hole in back up pad 21 is avoided in the covering position of the first pugging 3.For the fixture that cap 6 and back up pad 21 are interfixed, comprise two lock members (for example screw) and several buffer elements (for example rubber ring).Each lock member is all successively through the pilot hole in a pilot hole, a buffer element and the back up pad of a buffer element, cap 6, so that cap 6 is fixed to back up pad 21.Owing to can twisting tightly as between fixed bias circuit 4 and the screw of back up pad 21 for the fixing screw of cap 6 and back up pad 21, there is not great deformation in the buffer element between screw terminal and cap 6, cap 6 and back up pad 21, the vibration that therefore can further suppress back up pad 21 is delivered on cap 6.
Preferably, cap 6 also adopts sound-proof material to make, and can further noise being reflected back, the noise that color block component is produced is lower.
Preferably, cap 6 adopts Heat Conduction Material to make, to be conducive to the heat radiation of color block component.For example, cap 6 adopts metal material to make.In practice, the shell of color block component is generally made with metal material, and cap 6 preferably adopts the material the same with shell 2, makes color block component seem more attractive in appearance.
