Description
Technical field
The present invention relates to projection art, in particular to a kind of color wheel device.
Background technique
Currently, laser fluorescence powder technology is widely used in projection field, LASER Excited Fluorescence powder is used, fluorescent powder is produced
Raw fluorescence, the fluorescence is as light beam of light source, to be used for subsequent projection process.Fluorescent powder be stimulated generate fluorescence during
Heat can be generated, fluorescent powder will appear thermal saturation phenomenon and influence light extraction efficiency, it is therefore desirable to the substrate of driving carrying fluorescent powder
High speed rotation is in order to radiating.In addition, in order to adapt to high speed rotation state, fluorescent powder needs to be fabricated to molding phosphor powder layer.
A kind of existing scheme mixes fluorescent powder with organic adhesives such as silica gel, and the fluorescence for being mixed with organic adhesive is painted
It is applied on aluminum substrate, and aluminum substrate is connected in drive motor, to be fabricated to colour wheel.
The organic adhesives such as silica gel not resistant against high temperatures are limited to, and are not resistant to the strong factor of bloom, such colour wheel
Low-light level light intensity demand can only be met.Higher and higher brightness demand is required in order to realize, seeks a kind of to substitute organic bonding
Bonding agent of the inorganic adhesive of agent as colour wheel fluorescent powder becomes a kind of outlet solved the problems, such as.A kind of current feasible nothing
Machine bonding agent includes glass powder etc..Bonding can be just played since glass powder needs to melt at high temperature and further cool and solidify
Effect, and aluminum substrate cannot bear high temperature required for melting glass powder, therefore, aluminum substrate has been no longer desirable for carrying glimmering
Light bisque.Current thinkable solution is: the carrier using aluminium nitride substrate as carrying fluorescent powder, by fluorescent powder with
Glass powder for being bonded fluorescent powder is coated on aluminum nitride ceramic substrate, by it as sinter molding under high temperature；Further,
The ceramic substrate for carrying phosphor powder layer is Nian Jie using glue with aluminum substrate.Nearly all problem is all addressed.
Colour wheel is very high to requirement for dynamic balance under high speed rotation state；Each region weight of colour wheel it is inconsistent, will lead to color
Wheel waves under high speed rotation state, not only will increase noise, and will increase the load of motor, and then can shorten the longevity of colour wheel
Life.Therefore, generally before colour wheel enters operation, dynamic balancing test and adjusting will be carried out to colour wheel.Point is generally used in industry
The method of glue carries out dynamic balance adjustment to colour wheel.That is, the region point cementing lighter in colour wheel, to increase the weight in the region,
To adjust the dynamic balancing of colour wheel.Certainly, it can also be used and add other materials, such as steel ball, to adjust the dynamic balancing of colour wheel.
It is above-mentioned that aluminum nitride ceramic substrate setting to the colour wheel on aluminum substrate is run into a period of time by dynamic balance adjustment
Afterwards, and there is the unbalance problem of dynamic balancing.Dynamic balancing is adjusted again and is put into operation, is gone out once more after running a period of time
Existing dynamic balancing unbalance.
It has been investigated why colour wheel there is the unbalance problem of dynamic balancing repeatedly, be due to aluminum nitride ceramic substrate and
Caused by glue layer between aluminum substrate.During smearing, glue layer is difficult to smear uniformly, and by aluminium nitride ceramics base
In plate and aluminum substrate bonding process, the pressure for compressing the two applied is also difficult to be uniformly distributed in each area of glue layer
Domain, so that the thickness that will cause aluminium nitride ceramics and each region of glue layer is inconsistent.Glue is being converted into solid mistake from liquid
Cheng Zhong, glue itself generate stress (stress: object is due to external cause, for example, stress, temperature, moisture field variation etc., and when deforming,
In the internal force for generating interaction in object between each section, to resist the effect of this external cause and attempt to make object after deformation
Position be restored to deformation before position).The thickness in each region of glue layer is inconsistent, the stress intensity of the glue of different zones
It is different.
Colour wheel can all undergo biggish difference variation in test verification process and in actual use, test in test
Card during need by -40 DEG C to 85 DEG C high/low temperature recycle, in actual use, also can under operation 80
DEG C and do not switch between the environment temperature under operating status (for example, 20 DEG C or so) the two.Since the heat of aluminium nitride ceramics is swollen
Swollen coefficient is different from the thermal expansion coefficient of aluminum substrate, and the thermal expansion coefficient of aluminum substrate is probably the thermal expansion of aluminum nitride ceramic substrate
4 times of coefficient, the two pull power or pressure to glue layer formation in temperature course, can glue layer be deformed.Due to glue
The thickness in each region of layer is different and stress is also different, and glue layer different zones pull power aluminium nitride ceramics and aluminum substrate
Or different degrees of deformation is generated under pressure, so that the stress difference in each region of glue layer can be aggravated.Glue ply stress not
Under the combined effect of this double factor of uniformity and aluminum nitride ceramic substrate with aluminum substrate hot expansion system difference, glue layer is answered
It insists on to continue and change, also persistently change so as to cause glue layer form, and then lead to colour wheel dynamic balancing shape in use
State also persistently changes, and colour wheel dynamic balancing is unbalance to seriously affect the service life of colour wheel.
The colour wheel dynamic balancing as caused by adhesive layer is unbalance, which to be become, to solve the problems, such as.
