Description of the Invention: [Technical Field] The present invention relates to a light source dimming method, and more particularly to a method for adjusting the brightness of a light source by means of a switching method. [Prior Art] A conventional illumination device such as a white light, a fluorescent lamp, or an LED can provide a light source of a fixed brightness when it is illuminated, for an environment that does not require too high brightness at a specific time. In other words, the excessive brightness provided by the light source not only causes waste of electric energy, but also the light source cannot change the brightness according to the environmental demand to achieve the optimum light source brightness. Therefore, how to invent a method that can adjust the brightness of a light source is an urgent problem to be solved. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method for controlling brightness of a light source, which is used for adjusting the redundancy of a light source including a preset brightness of a plurality of segments. The light source dimming method includes: turning on the light source a light source, the light source is illuminated at a first order preset brightness; turning off the light source; turning the light source on again; the light source is illuminated at a second preset brightness, then changing to a third preset brightness and sequentially changing the brightness; Turning off the light source, turning the light source back on; the light source is clicked away from the preset brightness at which the light source is illuminated before the light source is turned off. [Embodiment] 201021622 Please refer to FIG. 1 'i' for the flow chart of the preferred embodiment of the present invention. As shown in FIG. 1, the present invention is for controlling the brightness of a light source containing multiple segments of brightness for adjustment. The number of segments is represented by x. The method of adjusting the light source is to first turn on the light source switch (S1). At this time, the light source is turned on. The brightness of the light source is the first-order preset brightness (S2), usually the brightest brightness or the darkest. Brightness, but not as P艮. Then turn off the light source switch (S3), turn off the light source switch, turn on the light source switch (S4) for the second time, and calculate the time T1 from the last time the switch is turned off to the time __ time T1. If it is greater than the preset time W, the step will return to S2, that is, the light source will be re-lighted at the first-order preset brightness. However, if the time T1 when the switch is turned off to the open switch is less than the preset time Td, the light source will illuminate at the second-order preset brightness (S5). The preset time Td is a fixed value and can be adjusted arbitrarily, and usually the second-order preset brightness is slightly darker or slightly brighter than the brightness, but not limited thereto. % Pre 5 When the light source is illuminated at the second-order preset brightness, if the light source is not turned off, the light source will change to the third-order pre-brightness (S6) after a buffering time. However, when the light source is illuminated at the second-order preset brightness, if the light source switch is turned off (S51) and then turned back on (S52), the time T2 when the light source switch is turned off and the light source switch is turned on is calculated again and again. And if the comparison is greater than the preset time Td', if the Τ2 is greater than the preset time Td, then return to step S2 to re-light the first-order preset brightness of the light source, if T2 is less than the preset time T (J then the light source is fixed at the second Preset brightness (S53). Similarly, when the light source changes to the third-order preset brightness (S6), if the light source is not turned off in 201021622, the light source will change to the fourth-order preset after a buffer time Tbuff. Degree, thus sequentially changing to the Nth-order preset brightness (Sn), where N is equal to the brightness segment number X of the light source. When the light source is illuminated at the third-order preset brightness, if the light source is turned off again (S61) After re-opening (S62), the time T3 when the last time the light source switch was turned off to the time when the light source switch was turned on will be calculated again, and whether T3 is compared

When the brightness of the light source changes to the Nth order preset brightness (Sn), if the light source switch is not turned off, the light source will be turned off after the buffer time Tbuff (Sn^l), and the right side will change the light source to the Nth order. Turn off the light source when setting the brightness, then the top light source (10), and calculate the time Tn when the light source is turned back on. If I Tn is greater than the preset _ Td, the light source will be re-lighted at the first-order preset brightness. Restart from step S2. However, if Τη is less than the preset time Td', the light source will be illuminated at the second-order preset brightness, and the above-mentioned action is restarted from step S5. The number of actions on pm / M: owed, H is different in the brightness of the different levels of light source "re-turn on the light source, and the switch turns on the light source switch; pre-" time Td' can light the light source before the preset light is turned off again In this way, the light source is illuminated at different brightness. The light source brightness control method of the light source is 'in addition to being able to control the single-simultaneous control of a plurality of light sources, because the ratio of each light source=201021622 may be different, which will cause the light source The difference in brightness change time becomes that a plurality of light sources cannot be synchronized in brightness change. Therefore, the present invention additionally utilizes 50 and 60 Hz AC power sources as reference power sources, and uses this reference power source to synchronize the brightness of the plurality of light sources to change the time. A plurality of light sources are synchronized in brightness change. Thus, through the operation of a simple light source switch, different light source brightnesses can be obtained to meet environmental requirements, while saving unnecessary power waste and prolonging the life of the light source.
