Embodiment
At first consult Fig. 1, this figure is the synoptic diagram of light source assembly among expression the present invention.As shown in the figure, light source assembly in the present embodiment is to be arranged at a projector inside, it mainly is made up of light shield 10, a solar heat-collection plate 12 and a light source 20 of a hollow, and wherein above-mentioned light source 20 is a based on halogen bulb, in order to provide projector required brightness.
As shown in Figure 1, above-mentioned solar heat-collection plate 12 is arranged between light shield 10 and the light source 20.Then please consult the 2nd, 3 figure and Fig. 4 more simultaneously, during assembling tool by the inner surface that solar heat-collection plate 12 is incorporated into light shield 10, again light source 20 is arranged at light shield 10 in.In the present embodiment, above-mentioned solar heat-collection plate 12 is sides that are positioned at light source 20, and be the central shaft C that is roughly parallel to light source 20, in order to receive the light (shown in arrow among Fig. 4) of the light source 20 part off-center axle C that sends, therefore can receive unemployed loss light further, and convert thereof into and be recycling electric energy.
In Fig. 4, the light that light source 20 is sent mainly is to advance along a first direction A1 who is parallel to central shaft C.Yet, in order to receive the light of off-center axle C effectively, the position that above-mentioned solar heat-collection plate 12 is provided with is than light source 20 more outstanding (as shown in Figure 4) on first direction A1, therefore can more effectively receive the light that is not utilized, and then reach the purpose of energy savings.
Then consult Fig. 5 again, this figure is the system block diagrams of projector among expression the present invention.As shown in the figure, the projector in the present embodiment is to use above-mentioned light source assembly structure, and except above-mentioned light source 20 and solar heat-collection plate 12, it mainly also comprises a microprocessor 30, a cooling system 40 and a power-supply system 50.Above-mentioned microprocessor 30 is to be electrically connected light source 20, in order to the switch of control light source 20.Light source 20 is opened simultaneously and is emitted beam when projector starts, and the loss light that wherein is not utilized then is to be converted to electric energy by solar heat-collection plate 12 receptions.
Particularly, can see through solar heat-collection plate 12 in the present invention as a system protection device, and can whether unusual in order to monitor above-mentioned cooling system 40.Wherein, when light source 20 is opened and the cooling system 40 of projector inside is not activated or during mal-operation, solar heat-collection plate 12 will because of heat up overheated send one the warning signal to microprocessor 30, after microprocessor 30 is received above-mentioned warning signal, drive 40 pairs of light sources of cooling system 20 immediately and implement cooling (for example can increase the rotating speed of fan in the cooling system 40), also can further in time send simultaneously an outage signal and close above-mentioned light source 20, damage because of overheated to avoid bulb.
On the other hand, above-mentioned power-supply system 50 is to be electrically connected above-mentioned solar heat-collection plate 12 and microprocessor 30, by solar heat-collection plate 12 transform light energy is become electric energy, can support and power supply system 50 part electric power, wherein power-supply system 50 also can comprise a chargeable cell apparatus, provide electric energy to battery charge by solar heat-collection plate 12, making projector not need to connect in addition external power source can use, and has improved the convenience that uses significantly.
In sum, the present invention proposes a kind of projector and light-source system thereof, can collect effectively by come out the but remaining luminous energy that do not utilized by ray machine (optical engine) of light source projects by solar heat-collection plate is set, and then can reach the purpose of energy savings.In addition; after bulb is lighted; solar heat-collection plate can be collected light and become electrical energy transfer to microprocessor thermal power transfer; inform that light source is lighted, in case and cooling system not during normal operation, microprocessor then can send the outage message; in time before bulb is impaired, stop power supply and close light source; so above-mentioned solar heat-collection plate also can be considered a system protection device of projector simultaneously except saving the energy, prolongs the serviceable life of light source and total system whereby.
Though disclose as above with preferred embodiment by the present invention; yet it is not in order to limit scope of the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; certainly can do a little changes and retouching, so protection scope of the present invention should be with being as the criterion that claims scope is defined.
