Description of the Invention: [Technical Field] The present invention relates to a light source module, and more particularly to a light source module applied to a projector. [Prior Art] Referring to FIG. 1A, there is shown a schematic diagram of internal components of a conventional projector 10, including a power supply 1, a ballast 2, a control circuit 3, and an optical engine. 4. Fan 5 and _ light source module 6. The circuit board 3 is connected to the power supply 1 and the security set 2. The light source module 6 includes a light bulb 61 corresponding to the optical engine 4 to provide light to the optical engine 4. The fan 5 blows an air flow 51 toward the light source module 6, and the air flow 51 passes through the surface of the bulb 61 to adjust the temperature of the bulb 61 and the inside of the projector 10. Referring to Fig. 1b, when the bulb form of the light source module 6 is replaced and the light source is provided by the bulb 61', the airflow 51 blown by the fan 5 will not directly contact the surface of the bulb 61'. This causes the bulb 61' to have a surface overheating problem, and also causes a temperature change inside the projector 10 due to the flow field and speed of the airflow 51. However, the temperature change inside the projector 10 (whether too high or too low) affects the projection effect of the projector 10. Therefore, in the prior art, if the bulb form of the light source module 6 is changed, the design of the light source module 6 needs to be changed. This large design change not only costs cost, but also slows down the shipment speed of the product. SUMMARY OF THE INVENTION 0535-A21475TWF(N2); A05319; LEM0N 5 200823590 The present invention provides a projector including a fan and a light source module in order to solve the problems of the prior art. The fan is used to drive a gas stream. The light source module is adjacent to the fan, and includes a light bulb, a lamp holder, and a flow guiding unit, the lamp socket includes a first side, the first side system includes a first opening and is adjacent to the fan, and the light bulb is disposed on the fan In the socket, the flow guiding unit is disposed on the first side and corresponds to the fan. The flow guiding unit includes a flow guiding component and a flow blocking component, the flow guiding component is adjacent to the first opening and guides the airflow to blow the light bulb, and the blocking component is disposed between the flow guiding component 10 and the fan To adjust the flow rate of one of the air streams. By applying the invention, when the form of the light bulb of the light source module is changed, only the design of the flow guiding unit needs to be changed, and the temperature of the bulb surface and the temperature inside the projector can be well controlled. This allows the producer to adjust the temperature inside the projector in a faster and more cost effective manner. [Embodiment] Referring to Figure 2, there is shown a projector 100 according to a first embodiment of the present invention, comprising a power supply 1, a ballast 2, a control circuit 3, and an optical engine. 4) The fan 5 and the light source module 200. The circuit board 3 is coupled to the power source 1 and the ballast 2 . The light source module 200 includes a bulb 210, a socket 220 and a flow guiding unit 230. The socket 220 has a first side 221 and a second side 222. A bulb 210 is disposed in the socket 220 corresponding to the optical engine 4 to provide light to the optical engine 4. The flow guiding unit 230 is disposed on the first side 221 and corresponds to the fan 5. The fan 5 blows an airflow 52 toward the light source module 200, and the airflow 52 is blown toward the bulb 210 through the flow guiding unit 230 to adjust the bulb 210 and 0535-A21475TWF (N2); A05319; LEM0N 6 200823590 temperature. Referring to FIG. 3, it shows a detailed structure of the light source module 200 of the present invention, wherein the socket 220 further includes a first opening 223, a second opening 224, a first filter 225, and a second filter. Web 226. A first opening 223 is formed on the first side 221, and a second opening 224 is formed on the second side 222. The first filter 225 is disposed above the first opening 223, and the second filter 226 is disposed above the second opening 224. A first opening 227 is defined in the first screen 225. The flow guiding unit 230 is disposed on the first side 221 and corresponds to the fan 5 and the third opening 227. The flow guiding unit 230 includes a frame body 231, a locking member 232, and a flow guiding member (guide vane) 233. The flow guiding element 233 is disposed above the frame 231. The locking element 232 secures the flow guiding unit 230 to the socket 220 in a detachable manner. The first screen 225 and the second screen 226 may be metal meshes. The airflow 52 is blown toward the bulb 210 through the flow guiding unit 230 and the first opening 223, and then flows out of the light source module 200 from the second opening 224. By applying the invention, when the form of the light bulb of the light source module 200 is changed, only the design of the flow guiding unit 230 needs to be changed, and the temperature of the bulb surface and the inside of the projector can be well controlled. Referring to Fig. 4, when the light source module 200 applies the bulb 210' to provide a light source, the producer can use the flow guiding unit 2301 to conduct the flow so that the airflow 52 is blown toward the surface of the bulb 210'. The inclination angle of the flow guiding element (the baffle) 233' of the flow guiding unit 2301 is different from the inclination angle of the flow guiding element (the deflector) 233 of the flow guiding unit 230 in Fig. 2 . Thereby, when the light bulb form of the light source module 200 is changed, the manufacturer can adjust and control the temperature of the projector inside the 0535-A21475TWF(N2); A05319; LEMON 7 200823590 in a faster and more cost-effective manner. Referring to Fig. 5, there is shown a second embodiment of the present invention, characterized in that the flow guiding unit 2302 further includes a baffle element for regulating the amount of air blown toward the bulb 210. The temperature inside the projector 100 can be separately maintained while being projected in the first mode (normal mode) and the second mode (energy saving mode). With reference to FIG. 6a and FIG. 6b, in the second embodiment, the flow guiding unit 2302 further includes a guiding groove 242 disposed on the frame 231. The syllable element 241 is disposed in the guiding slot 242 and is in a translational manner in a first position (the position shown in FIG. 6a) and a second position (the position shown in FIG. Move between. When the projector 10 is projected in the first mode (normal mode), the baffle element 241 is in the first position, at which time the baffle element 241 does not block the flow path of the air flow 52. When the projector is projected in the second mode (energy saving mode), the current blocking element
