Description

Technical Field

[0001] This invention relates to the field of light source attenuation technology, and in particular to a light source adaptive control method. Background Technology

[0002] In the current technology, the light sources on the market suffer from several problems during use. First, different equipment testing items require different light sources, resulting in variations in light source size and power. Second, the shapes of the objects being tested are diverse, leading to differences in light source size and power. Third, different light sources have different power, voltage, and current, making it impossible to match them with the same constant current driver. Fourth, it is impossible to confirm the lifespan status of the LED light source (whether it is experiencing light decay, aging, or abnormal brightness) after the light source has been lit for a long time. All of these problems contribute to the inability of the light source to adaptively compensate after light decay.

[0003] Regarding the issue that existing light sources cannot adaptively compensate for light decay, there is still a lack of better technical solutions. Summary of the Invention

[0004] In view of this, it is necessary to provide a light source adaptive control method to at least solve the problem in related technologies that the light source cannot adaptively compensate after light decay.

[0005] This application provides a light source adaptive control method, including the following steps: S1. Based on the user's required light source brightness, set the preset illuminance L to correspond to the brightness. 设 And record the total usage time t of the light source. 总 ; S2. The user collects data parameters of the light source in real time through the monitoring device. The data parameters include the real-time temperature T. 实 Real-time illuminance (L) 实 Real-time current I 实 and real-time voltage U 实 ; S3. Based on the attenuation characteristics of the light source, as the total usage time t of the light source increases... 总 Variable length and real-time temperature T of the light source 实 The higher the temperature, the higher the real-time illuminance L of the light source. 实 The illuminance is gradually reduced, and a light source attenuation model is established to obtain the simulated illuminance L. 拟 Total usage time t 总 Simulated illuminance L 拟 With real-time temperature T 实 and simulated current I 拟 With real-time temperature T 实 The correspondence is established; and by analyzing the correspondence, it is determined whether the current light source is attenuating. If it is determined that the light source is attenuating, the real-time current I of the light source is adjusted. 实To achieve the real-time illuminance L of the light source 实 Infinitely close to simulated illuminance L 拟 This allows the light source to stably output the preset illuminance L. 设 ; S31, through simulated illuminance L 拟 Total usage time t 总 The correspondence formula L 拟 = -1020ln(t 总 The simulated illuminance L is obtained by adding 38674. 拟 By simulating illuminance L 拟 With real-time illuminance L 实 Compare and determine the real-time illuminance L. 实 Whether it is affected by the total usage time t 总 If there is no effect, proceed to the next step; if there is, adjust the real-time current I. 实 Make real-time illuminance L 实 Infinitely close to simulated illuminance L 拟 When the adjusted real-time illuminance L 实 Located at simulated illuminance L 拟 After setting the preset range, proceed to the next step; S32, through simulated illuminance L 拟 With real-time temperature T 实 The correspondence formula L 拟 = -0.059x2 + 13.63xT 实 +0.5 to obtain the simulated illuminance L 拟 By simulating illuminance L 拟 With real-time illuminance L 实 Compare and determine the real-time illuminance L. 实 Whether it is affected by real-time temperature T 实 If there is no effect, proceed to the next step; if there is, adjust the real-time current I. 实 Make real-time illuminance L 实 Infinitely close to simulated illuminance L 拟 When the adjusted real-time illuminance L 实 Located at simulated illuminance L 拟 After setting the preset range, proceed to the next step; S33, via simulated current I 拟 With real-time temperature T 实 Correspondence formula I 拟 = -1.1148x2 + 50.285xT 实 + 701.31, calculate the simulated current I. 拟 If not, complete the entire adjustment; if yes, adjust the real-time current I. 实 Make real-time illuminance L 实Infinitely close to simulated illuminance L 拟 When the adjusted real-time illuminance L 实 Located at simulated illuminance L 拟 After setting the range, complete the entire adjustment.

[0006] The beneficial effects of this invention are: the design of this application is reasonable. It uses an attenuation model to determine whether the illuminance of the light source is attenuated. When the illuminance of the light source is attenuated, the working current of the light source is adjusted to compensate for the attenuation of the light source, so as to achieve a stable output of luminous flux.
