[0052] see figure 1 , which is a flowchart of a method for stabilizing a light source provided in an embodiment of the present application.
[0053] like figure 1 As shown, the method for stabilizing the light source provided in this embodiment includes:
[0054] Step 101: Obtain the light intensity value of the light source.
[0055] In this embodiment, the light source may be a light emitting diode (light-emitting diode, LED), and the light source is modulated by the AC component of the driving signal. As an example, the AC component could be a sine wave, square wave, sawtooth wave, etc.
[0056]The light intensity value of the light source can be obtained in many ways. For example, the light radiated by the light source with a large radiation angle is converged into a beam and directed to the photodetection element, and then the photodetection element converts the light energy into a current. The amplitude of the signal determines the light intensity value of the light ...

[0065] see figure 2 , which is a flow chart of another method for stabilizing a light source provided in this application.
[0066] like figure 2 As shown, the method for stabilizing the light source provided in this embodiment includes:
[0067] Step 201: Detect and obtain the light intensity value of the light source by using a light detection element.
[0068] In this embodiment, the rated power of the selected light source is not lower than the actual required power of the light source. For example, the rated power of the light source is greater than or equal to twice the actual required power of the light source.
[0069] In addition, the light source can also be subjected to aging treatment in advance. The following provides a specific implementation of aging treatment: place the light source within the maximum ambient temperature allowed by the light source, drive the light source with the maximum current allowed by the light source, and work for 48 hours. Of cou...

[0102] see Figure 9 , which is a schematic structural diagram of a device for stabilizing a light source provided in the present application.
[0103] like Figure 9 As shown, the device for stabilizing a light source provided in this embodiment includes: a light intensity acquisition module 901 and a light source stabilization module 902 .
[0104] Wherein, the light intensity acquisition module 901 is used to acquire the light intensity value of the light source;
[0105] The light source stabilizing module 902 is configured to use the DC component of the driving signal of the light source to stabilize the light source according to the light intensity value, wherein the light source is modulated by the AC component of the driving signal.
[0106] The above is a device for stabilizing the light source provided by the embodiment of the present application. Because it is modulated by the AC component of the driving signal, the light intensity of the light source is positive...
