The invention discloses a multi-LED light-emitting source control system, comprising: a plurality of LED light-emitting sources, a plurality of LED drive modules, a statistics module and a control module, and the statistics module is used for counting the quantity of abnormal LED light-emitting sources and non-abnormal LED light-emitting sources , the number of abnormal LED light sources is recorded as A, and the number of non-abnormal LED light sources is recorded as B. The LED light sources correspond to the LED drive module one by one. When the control module calculates the first current value, it is used as the target current value. , otherwise as the target current value, the control module controls the LED driver module corresponding to the non-abnormal LED light source to output the target current value. By changing the driving current of the non-abnormal LED light source, the brightness loss caused by the abnormal LED light source is compensated to the greatest extent. Solved the problem that the brightness decreased significantly due to the abnormality of the LED light source. The invention is mainly used in the technical field of lighting.
Description
technical field [0001] The invention relates to the technical field of lighting, in particular to a multi-LED light source control system. Background technique [0002] Existing lamps have a lighting scheme composed of multiple light emitting sources. For this lighting scheme, when one or several light emitting sources have problems, such as failure, the brightness of the entire lamp will be significantly reduced. This obvious decrease in brightness is something that many lamp users do not want to see. Therefore, how to avoid this situation is an urgent problem to be solved in the industry. Contents of the invention [0003] The purpose of the present invention is to provide a multi-LED light source control system to solve one or more technical problems in the prior art, and at least provide a beneficial option or create conditions. [0004] The solution of the present invention to solve the technical problem is: a multi-LED light-emitting source control system, includin...
