[0047] Please refer to Figure 1A , Figure 1A A block diagram of a projection device according to a first embodiment of the present invention is shown. The projection device 100 mainly includes: a power supply system 101, a light source 103, an optical machine 105, a lens 107 and an energy recovery module 109 (such as Figure 1A within the dotted line shown). The power supply system 101 provides power for main components such as the light source 103 and the light engine 105 , and also provides power for the fan 110 and the electronic ballast 113 (Ballast). Wherein, the electronic ballast 113 is used for stably rectifying and lighting the light source 103 . The light generated by the light source 103 is guided by the light engine 105 , and after passing through the lens 107 , a projection image is generated. The path of light passing through the light source 103 , the optical machine 105 to the lens 107 forms an optical path 111 . The casing 104 of the projection device 100 ...

[0052] Please refer to figure 2 , figure 2A thermoelectric semiconductor configuration diagram is shown. Different from the first embodiment, in the second embodiment, thermoelectric semiconductors 202a-c can be added to absorb heat energy and convert it into electrical energy. In the entire projection device 200 , the temperature distribution can be used to find the region with a large temperature difference. For example, the temperature near the light source 203 is generally higher, and the temperature difference with the surrounding environment is also larger, so the heat transfer efficiency is higher, so the recyclable energy and efficiency of disposing the thermoelectric semiconductor 202a are also higher. Near the fan 210, the heat flow rate and the temperature difference are relatively large, so the thermoelectric semiconductor 202b can also be placed. Similarly, the thermoelectric semiconductor 202c can also be placed around the electronic ballast 213 . If combin...

[0054] Different from using the flow path system 109a, the method of recovering heat energy in this embodiment is to use a Stirling Engine to perform. Please also refer to Figure 3A and Figure 3B , Figure 3A A graph showing pressure versus specific volume for a Stirling engine. Figure 3B A schematic diagram showing the movement of the pistons in a Stirling engine. As in the first embodiment, the Stirling engine 320 is arranged near the light source, the high temperature emitted by the light source or the high temperature of other electronic components can heat the gas 324 arranged in the Stirling engine 320, so that the Stirling engine 320 Piston 322 reciprocates (such as x1 direction), where P is pressure, V is specific volume (the product of PV is work), and the constant change and circulation of specific volume V and pressure P include compression d1, heat absorption d2, expansion In the four states of d3 and exothermic d4, the piston 322 will continue to move and p...
