Concrete example is as follows: to have transmittance in whole optical path be example in order to be excited material, described zone so that to adopt the blue-ray LED array be excitation source, fluorescent material, when a regional controlled selection that carries yellow fluorescent powder enters light path, light source output light presents white, is the secondary colour of blue excitation light and yellow stimulated luminescence.When the heat radiation substrate adopted transparent material or each zone to be nested in the through hole of heat radiation substrate, the utility model device can further include towards described guiding device, was arranged in the heat radiation substrate or near the optical filter or the filter coating of this heat radiation bases; This optical filter or filter coating are used for the light that gating has predetermined wavelength range or predetermined shooting angle scope.For example, blue filter of incision is come the filtering blue light in the light path between described heat radiation substrate and described guiding device, and what go into light path is the zone that carries yellow fluorescent powder if described heat radiation substrate is enterprising, and then light source output light presents yellow; What go into light path is the zone that carries red fluorescence powder if described heat radiation substrate is enterprising, and then light source output light presents redness; What go into light path is the zone that carries green emitting phosphor if described heat radiation substrate is enterprising, and then light source output light presents green; Or the like.Equally, the optical filter with UV light LED and filtering UV light also can cooperate different fluorescent material to produce different color light.When described optical filter or filter coating have gate action to the light output angle, then can improve the dispersion angle of light source output light, even the output light of low dispersion angle can be provided, thereby can consider whether use second collimation lens 5 as one sees fit.Consider that described light wavelength conversion wheel goes up the light of stimulated luminescence and partly understand the directive excitation source, for effectively stimulated luminescence being derived, the utility model device can also be simultaneously on heat radiation substrate 40 or conducting strip 47 plane of incidence of exciting light apply or be provided with a filter coating or the optical filter with optical wavelength selection effect, this filter coating or optical filter reflection stimulated luminescence and permission exciting light pass through, then will effectively derive stimulated luminescence, further improve the brightness that the utilization rate of stimulated luminescence is improved light source output light greatly.Because the optical wavelength of exciting light is less than stimulated luminescence usually, this filter coating or optical filter can adopt optical low-pass filter, also promptly see through short wavelength's light, reflection long wavelength's light.
Further, the control module in the utility model device can also be controlled simultaneously to exciting light and telecontrol equipment.For example when described control module control light wavelength conversion wheel assembly 4 moved, the power supply source of exciting light was cut off in control; When waiting this light wavelength conversion wheel assembly 4 static, the exciting light power supply source is opened in control again.This will produce color and present the stimulated luminescence that jumping characteristic changes.
Can carry out by turns for emergent light color is changed, the utility model is all right to be provided with or predefined change color pattern according to artificial, start described control module in good time or intermittently, carries out predetermined zone selection or optical filter and selects.Described control module can comprise stepper motor, drives described light wavelength conversion wheel assembly motion by this stepper motor driven gear group.Therefore, start and control the intermittence that can utilize existing digital circuit technique to finish above-mentioned control module.Because of it is a prior art, non-the utility model emphasis is not given unnecessary details at this.
In the utility model device, each zone changes the color or colour temperature of light source emergent light in relying on described light wavelength conversion wheel assembly 4, and the means that can also be used in combination comprise the colour temperature of utilizing different excitation sources to adjust the light source emergent light.For example, excitation source described in the various embodiments described above is example with monochromatic light, if excitation source comprises LED or the led array with two or more emission wavelength, for example sneak into red on a small quantity (R) light LED in the blue-ray LED array, be equipped with gold-tinted fluorescent material, then will in the white light output of light source, increase a little ruddiness compositions.Perhaps consider photodistributed uniformity, can organize into described red-light LED separately array, as shown in Figure 6, by beam split Multiplexing apparatus 3 ' become deciliter light to go into the exciting light light beam this ruddiness.These no longer describe in detail because of non-the utility model emphasis.
