Kind of primary colours most bright spot is brighter and the most bright spot of other primary colours than dark, then can be scaled up the primary colours fluorescent lifetime or
Person's intensity.Since the optical information that human eye senses within the time of a frame picture is the integration to all light in the time, because
This, as shown in (a) in Fig. 2, both can obtain picture in a manner of the low fluorescent lifetime ratio of high brightness (as shown in arrow E1)
Required brightness, can also the high fluorescent lifetime ratio of low-light level mode (as shown in arrow E2) come bright needed for obtaining picture
Degree, as long as total light energy is identical, the display effect of two ways is the same.Wherein, dynamically adjusted according to image information
Fluorescent lifetime ratio and luminous intensity can improve the utilization rate of luminous energy, so as to reduce energy consumption or can promote the bright of monochrome
Degree keeps the brightness of monochrome constant, reduces the power of excitation light source to reduce energy consumption.
Specifically, every frame image information can be analyzed, finds the most bright spot of every two field picture red, green, blue three primary colours, root respectively
It adjusts the fluorescent lifetime ratio of different base colors light in a frame image time according to the brightness ratio of red, green, blue three primary colours and shines strong
It spends to meet display needs.
For example, when showing desert landscape image, it, can be by controlling the light path changing device as shown in (a) in Fig. 2
12 and the first light source 151 of transmitting red laser beam, make the fluorescent lifetime ratio of R primary lights increase, and G, B primary lights it is luminous when
Between ratio reduce, it is possible to low-power consumption mode meets display demand, so as to achieving the purpose that power saving.
And corresponding to the hi-bright mode of projecting apparatus, as shown in (b) in Fig. 2, by increasing fluorescent lifetime ratio and shining
The mode of intensity can obtain the output image of high brightness.
It should be noted that when adjusting primary colours luminous intensity, the luminosity of Wavelength converter and laser light source is to driving
The response of streaming current is all nonlinear.As shown in Figure 3-4, according to the data (having done normalized) of experiment gained, laser
When intensity and fluorescence intensity reach the half of maximum, driving current size respectively about 0.42 and 0.37.Meanwhile driving current
Suddenly change can influence heat dispersal situations, so as to influence the luminous efficiency of Wavelength converter and laser.Therefore, adjusting
, it is necessary to the regulated value of the good driving current of the measured in advance that takes one thing with another during luminous intensity.And when adjusting fluorescent lifetime ratio,
The amplitude of electric current suddenly change is smaller, and situation is slightly different with adjusting primary colours luminous intensity, therefore its current regulation value also can
It is different, it is necessary to separately adjust compared with.

One gamut range F1 is the gamut range that stimulated light can be shown, the second gamut range F2 is the colour gamut model that laser can be shown
It encloses.As seen from Figure 5, after laser is added in as primary lights, the colour gamut of the emergent light of the light-source system 10 has obtained pole
Big expansion.Wherein, if the picture colour gamut of actual needs display is fallen into the colour triangle scope of stimulated light, in this frame
In picture, without lighting the first light source 151 for emitting laser, secondary light source 152, the 3rd light source 153, using only stimulated light
It can meet display requirement as primary lights.If display picture colour gamut beyond stimulated light colour triangle scope,
Colour gamut can be expanded by way of lighting the first light source 151 for emitting laser, secondary light source 152, the 3rd light source 153,
With the color of the primary lights of mixing display frame out true to nature, while picture brightness can also be promoted.It is appreciated that swashed using pure
Light primary lights can also reach the colour gamut of this broadness, but due to the high coherence of laser, it may appear that speckle influences display quality.
This light-source system 100 of the utility model can be according to the fluorescent lifetime ratio of each primary lights of image information dynamic regulation
