Referring to fig. 1, the present embodiment provides a light source assembly 130 and a projector optical engine 100 including the light source assembly 130. This projector ray apparatus 100 can be applied to the projecting apparatus, has the good characteristics of radiating effect, is favorable to avoiding or reducing because of the overheated light decay phenomenon that leads to of light source and burning out the light source, can make the light source heat dissipation good, guarantees the result of use and the life of projecting apparatus to promote user experience.
In the embodiment of the present invention, the projector optical engine 100 includes a fan 110, a heat sink 120 and a light source assembly 130, wherein the light source assembly 130 may include a heat spreader 131 and at least one light source module 132, the at least one light source module 132 is disposed on the heat spreader 131, the heat spreader 131 is connected to the heat sink 120, and the fan 110 is configured to flow air through the heat sink 120 to take away heat from the heat sink 120.
It should be understood that in embodiments of the present invention, light source module 132 operates and generates heat when projector light 100 is in use. The light source module 132 is disposed on the heat spreader 131, and heat generated by the light source module 132 is transferred to the heat spreader 131 and then transferred to the heat sink 120 through the heat spreader 131. The fan 110 can take away heat transferred to the heat sink 120 in the form of air flow. That is, in the embodiment of the present invention, the heat transfer paths of the light source module 132 are sequentially: the light source module 132, the soaking plate 131, the heat sink 120, and the fan 110 takes away the heat of the heat sink 120 in the form of air flow, thereby achieving heat dissipation of the light source.
In the embodiment of the present invention, the soaking plate 131 has good heat conduction efficiency, and can well diffuse heat into the whole soaking plate 131 structure, thereby achieving better heat dissipation. For the light source module 132, the heat generated during the operation is concentrated on the soaking plate 131 directly contacting with the light source module 132, and the soaking plate 131 can transfer the heat of the portion to other portions of the soaking plate 131, that is, the soaking plate 131 can rapidly diffuse the heat of the portion contacting with the light source module 132 to other portions, thereby realizing the heat dissipation of the portion contacting with the light source module 132 and the soaking plate 131, and also realizing the heat dissipation of the light source module 132. The heat sink 120 is connected to the soaking plate 131, and the heat of the soaking plate 131 is further transferred to the heat sink 120; the fan 110 can promote the air flow of the heat sink 120 and its vicinity, and the air flow takes away the heat, thereby dissipating the heat from the heat sink 120.
It should be noted that, in the prior art, the light source of the projector optical engine 100 transfers heat to the heat pipe (or the heat conducting copper pipe) through the heat conducting copper block, the heat pipe is connected with the heat dissipating fins, and the heat on the fins is taken away through the fan 110. That is, in the prior art, the heat transfer path is sequentially as follows: the heat of the light source, the heat conducting copper block, the heat pipe and the fins is taken away in the form of air flow through the fins of the fan 110, and the heat dissipation of the light source is realized. Generally, the heat conduction copper pipe is attached to the heat conduction copper block, namely the heat conduction copper block and the heat conduction copper pipe are two different parts and are connected through a heat conduction material, and the heat conduction material can bring large thermal resistance and influence the timely heat transfer; that is, heat is accumulated on the heat conducting copper block and cannot be timely transferred to the heat conducting copper pipe, which affects the heat dissipation effect of the light source. Meanwhile, the sizes of the heat conducting copper block and the heat conducting copper pipe are different, and heat on the heat conducting copper block cannot be uniformly transferred to the heat conducting copper pipe when being transferred to the heat conducting copper pipe; that is to say, the heat transfer of the part of the heat-conducting copper block directly connected with the heat-conducting copper pipe is faster, while the heat transfer of other parts is slower, and the heat transfer of the light source heat can be influenced by the uneven heat on the heat-conducting copper block.
In the projector optical engine 100 according to the embodiment of the present invention, the soaking plate 131 can rapidly disperse the concentrated heat to each part of the soaking plate 131, and the heat is substantially uniform on the soaking plate 131; the light source module 132 is disposed on the soaking plate 131, and rapid heat transfer can be achieved. The soaking plate 131 can make the heat on the soaking plate 131 substantially uniform, and then the heat of the soaking plate 131 is transferred to the heat sink 120 through the heat sink 120. Compared with the prior art, the embodiment of the invention has better heat dissipation effect and is beneficial to reducing or avoiding overheating of the light source.
In addition, it should be noted that, in the above prior art, the heat pipe (or the heat conducting copper pipe) is generally in a shape of a circular pipe, the contact area between the heat pipe and the heat conducting copper block is small, and the contact portion between the heat pipe and the heat conducting copper block is connected through the heat conducting material, so that the heat conducting effect is greatly influenced. Although the circular tube can be machined into an oblate shape or a specific part can be machined into a plane through machining, so that the contact area between the circular tube and the heat-conducting copper block is enlarged, and the heat transfer is improved, a larger thermal resistance still exists at the joint of the heat-conducting copper block and the heat pipe. Meanwhile, the heat transfer of the heat pipe is one-dimensional, the heat diffusion is limited, and the heat transfer efficiency is further influenced. In the embodiment of the present invention, the soaking plate 131 can rapidly transfer heat to each part, and can realize heat transfer in both horizontal and vertical directions, and the soaking plate 131 is a two-dimensional heat transfer, and has a significant heat transfer advantage compared with the one-dimensional heat transfer of a heat pipe.
In addition, for the soaking plate 131, which has a good heat conducting effect, the heat sink 120 can be reduced in volume accordingly, so that the soaking plate 131 and the heat sink 120 can occupy a smaller volume.
Alternatively, the light source module 132 may be a red light module, a green light module, a blue light module, and the like, and correspondingly emit red light, green light, blue light, and the like. In the figure, R denotes a red light module; g represents a green light module; b represents a blue light module; bp represents Blue pumping Blue excitation for boosting brightness.

The heat generated by the light source module 132 can be transferred through the soaking plate 131, which is beneficial to improving the heat dissipation efficiency of the light source module 132 and improving the heat dissipation effect thereof.
