Then, power-brightness matching module 402 determines meet condition first according to target brightness value, table 1 and table 2
The-the second target power of target power combines.In the present embodiment, meet the-the second target power of first object power of condition at this time
Combination for example has 90%P1-0%P2 (only having the first lamp source 100 to work at 90%P1, the second lamp source 200 is closed), 70%
P1-70%P2 (the first lamp source 100 works at 70%P1, while the second lamp source 200 works at 70% time), 80%P1-50%
P2 (the first lamp source 100 works at 80%P1, while the second lamp source 200 works at 50% time) and 30%P1-90%P2 (first
Lamp source 100 works at 30%P1, while the second lamp source 200 works at 90% time).Any combination is finally selected as final
First object power and the second target power can be determined by preset selection strategy in processor 400.For example, if
Preset selection strategy is that the first lamp source 100 and the second lamp source 200 is allowed to be determined in a manner of average dispersion brightness, then above-mentioned
It can be this combination of 70%P1-70%P2 to meet the preferred combination in the-the second target power of first object power combination of condition,
So when final first object power and the second target power be respectively 70%P1 and 70%P2；With the side of average dispersion brightness
Formula determines to be advantageous in that the burden of lamp source is average, can be replaced by the gross when more to change the bulb.If preset selection
Strategy is to allow a wherein lamp source to be exported as main brightness, and another lamp source is determined as the mode of auxiliary brightness output,
Then it is above-mentioned meet condition the-the second target power of first object power combination in preferred combination can be 80%P1-50%P2 this
One combination, first object power final at this time and the second target power are respectively 80%P1-50%P2, and the benefit of this strategy exists
In higher power is used for the first lamp source 100, the service life of the first lamp source 100 can be less than the use of the second lamp source 200
Service life, and when the first lamp source 100 can not in use, still can use the second lamp source 200 be single light source work on by projector,
And it is unlikely to the awkward situation that two lamp sources occurs while can not use.Illustrated by taking above two selection strategy as an example, but not with
This is limited, in other embodiment, in the case where there is multigroup the-the second target power of first object power combination to meet condition,
Randomly selected strategy can also be used, it is random to determine to combine as final the-the second target of first object power using which
Power combination.In this present embodiment, preset selection strategy is to allow the first lamp source 100 and the second lamp source 200 with average mark
The mode for dissipating brightness determines.Finally, power regulation module 403 according to preset selection strategy by the of the first lamp source 100
One power adjustment is to 70%P1 (brightness value of corresponding first light beam 101 be 1100lm) and by the second work(of the second lamp source 200
Rate is adjusted to 70%P2 (brightness value of corresponding second light beam 201 is 1000lm).Thus above-mentioned light-source system 1000 can produce
The light beam of light combination 301 that raw brightness is 2100lm.
It should be noted that above-mentioned setting value only illustrates, true brightness number is not represented.It illustrates herein
In explanation, the maximum power of the first lamp source 100 and the second lamp source 200 simultaneously differs, and but not limited to this, in practical operation,
The maximum power of first lamp source 100 and the second lamp source 200 also can be identical.
In practical operation, in order to ensure the brightness value for the light beam of light combination 301 being emitted from closing light pipe 300 is user's needs
Target brightness value, whether the brightness value that light beam of light combination 301 is sensed using brightness sensing device 500 is target brightness value.If closing light
The brightness value of light beam 301 is target brightness value, then brightness sensing device 500 sends the first feedback signal to processor 400, processor
400 work normally according to the first feedback letter command projector, in other words, current first object power the-the second target power group
Conjunction is suitable, under current the-the second target power of first object power combination, the first light beam that the first lamp source 100 is sent out
101 and second the second light beam 201 that sends out of lamp source 200 in the conjunction that can obtain that there is target brightness value after closing light pipe 300
Light light beam 301, in the case, processor 400 can enable projector start work；If the brightness value of light beam of light combination 301 differs
In target brightness value, then the second feedback signal of transmission of brightness sensing device 500 to processor 400, processor 400 are fed back according to second
Signal regenerates new the-the second target power of first object power combination, that is to say, that current first object power-the
The combination of two target powers is inappropriate, under current the-the second target power of first object power combination, the first lamp source 100
The second light beam 201 that the first light beam 101 and the second lamp source 200 sent out is sent out cannot be had after closing light pipe 300
The light beam of light combination 301 of target brightness value, in the case, 400 Bu Ling projectors of processor open work, but regenerate new
The-the second target power of first object power combination.
Specifically, the overall process for regenerating new the-the second target power of first object power combination is as follows：Power-
Brightness matching module 402 receives after the second feedback signal in current the first power-brightness relationship table and the second power-brightness
It is searched in relation table and determines new the-the second target power of first object power combination.If power-brightness matching module 402
