Below in conjunction with accompanying drawing and embodiment the utility model embodiment is elaborated.
Technical term is explained:
Thermal conductivity factor: under the steady heat transfer condition, the material that 1m is thick, the temperature difference of both side surface is 1 degree (K), the heat that in 1 second, transmits through 1 square metre of area, unit be watt/(Mi Du), i.e. W/ (mk).
Embodiment one
See also Fig. 2, Fig. 2 is the side view of an embodiment of the utility model embodiment medium wavelength conversion equipment.
Wavelength converter 2 comprises and is used to the wavelength conversion layer 100 that absorbs exciting light and produce Stimulated Light; Be used to drive the drive unit 200 that this wavelength conversion layer 100 makes wavelength conversion layer 100 periodic rotary; And the thermal insulation layer 300 between wavelength conversion layer 100 and drive unit 200, wavelength conversion layer 100 is fixedly connected on the drive unit 200 through this thermal insulation layer 300.
Through in the middle of substrate 110 and drive unit 200, thermal insulation layers 300 being set; To avoid substrate 110 to contact with the direct of drive unit 200; Effectively stoped the heat of wavelength conversion layer 100 to be delivered on the drive unit 200, avoided the problem of drive unit because of the higher decline in service life of long-term work temperature.In the utility model; With the drive surface of drive unit 200 be the bottom surface, with the thickness (being the distance of drive surface to wavelength conversion layer) of thermal insulation layer 300 for the thermal conductivity factor of high each several part in cylindrical is the weighted average of weight during less than 10W/ (mk) with the volume of each several part, can reach heat insulation purpose.Be understood that easily; As long as above-mentioned cylindrical in; Change along thermal conductivity factor on the direction that is parallel to drive surface; And along constant perpendicular to thermal conductivity factor on the direction of drive surface, the thickness that then above-mentioned columniform each several part is with thermal insulation layer 300 is high cylindricality, and this moment, above-mentioned weighted average should be the weighted average of weight with the base area of the each several part in cylindrical promptly.
In the present embodiment, thermal insulation layer 300 is the thermal insulation board 300 of the drive surface (being the end face of rotating shaft 210) of covering drive unit 200.Thermal insulation board 300 is a solid slab; And adopt the relatively poor material of heat conductivility to process; For example thermal conductivity factor is less than the material of 10W/ (mk); Thereby be the bottom surface, be that the weighted average of weight is less than 10W/ (mk) for the thermal conductivity factor of high each several part in cylindrical with the volume of each several part with the thickness (being the distance of drive surface to wavelength conversion layer) of thermal insulation board 300 with the drive surface of drive unit 200; Thereby the heat that can stop wavelength conversion layer 100 to produce effectively is delivered on the drive unit 200, makes the long-term work temperature of drive unit 200 lower.
More preferably, above-mentioned weighted average is less than 1W/ (mk).The thermal insulation board 300 preferred relatively poor macromolecule polymeric materials of heat conductivility that adopt are processed, for example rigid plastics, lucite.In addition, the material of thermal insulation layer preferably has higher intensity, and the fixture of thermal insulation layer both sides brings its stress when bearing revolution.Rigid plastics for example because its thermal conductivity factor low (often less than 1W/ (mk)), mechanical strength good be easy to machining characteristics, become the preferred material of present embodiment thermal insulation board 300.
In addition, because the luminous efficiency and the inversely proportional relation of temperature of material for transformation of wave length, promptly the temperature of material for transformation of wave length is low more, and the luminous efficiency of material for transformation of wave length is just high more.The most directly effective method that reduces the material for transformation of wave length temperature is to use the good material of heat conduction to make the substrate that carries the material for transformation of wave length sheet.Material for transformation of wave length is excited the heat that produced like this, have quite a few and led away and spread by substrate and come, and then the temperature of material for transformation of wave length is minimized.Therefore, the substrate 110 preferred thermal conductivity factors that adopt are processed greater than the material of 40W/ (mk).More preferably, substrate 110 fits tightly with material for transformation of wave length sheet 120, and adopts thermal conductivity factor to process greater than the metal of 40W/ (mk), for example aluminium, copper or iron.
Compared with prior art; In the present embodiment; Through between wavelength conversion layer and drive unit, thermal insulation board being set; And be the bottom surface, be that the thermal conductivity factor of high each several part in cylindrical is that the weighted average of weight is less than 10W/ (mk) with the volume of each several part with the thickness of thermal insulation board with the drive surface of drive unit; Thereby the heat that can stop wavelength conversion layer to produce is delivered on the drive unit, make the long-term work temperature of drive unit low and service life is higher, thereby the service life of colour wheel and whole light source is also higher.And the material for transformation of wave length in the present embodiment is owing to be arranged at heat conductivility preferably on the substrate, thereby material for transformation of wave length has, and temperature is lower, the luminous efficiency advantage of higher, and has the advantage of growing service life owing to temperature is lower.
