Problems solved by technology

However, before the general LED flexible light strip leaves the factory, it usually only detects its on and off. The general operation is to turn on the switch, judge whether the LED light is bright, turn off the switch, and judge whether the LED light is off. However, using this method for detection, the measurement method is relatively simple, which cannot effectively guarantee the reliability of the flexible light bar

Abstract

The invention provides an online detection method for an LED soft lamp strip. The method comprises the steps: scanning and obtaining the current position structures of all target LED patches in a LEDsoft lamp strip and a substrate provided with all target LED patches based on a laser scanning technology; based on a luminous flux measurement technology and a pre-stored luminous flux database, measuring and obtaining luminous flux of all target LED patches in the LED soft lamp strip in a preset time period; establishing a current mapping relationship between the obtained current position structure and the luminous flux; and performing online detection on the LED soft lamp strip based on a pre-stored detection database related to the LED soft lamp strip and the established current mapping relationship, obtaining a detection result related to the LED soft lamp strip, judging whether the LED soft lamp strip is qualified according to the detection result, and outputting the LED soft lamp strip. Through the combination of various technologies, the LED soft lamp strip is detected on line, and the reliability of detecting the LED soft lamp strip is improved.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an online detection method for LED flexible light strips. Background technique [0002] The LED flexible light strip uses FPC as the assembly circuit board and is assembled with SMD LEDs, so that the thickness of the product is only the thickness of a coin and does not take up space. The general specifications of LED flexible light strips are 30cm long, 18 LEDs, 24 LEDs, and 50cm long, 15 LEDs, 24 LEDs, 30 LEDs, etc. There are also 60cm, 80cm, etc. Different users have different specifications. The LED flexible light strip can be cut or extended at will without affecting the light emission. The FPC material is soft, can be bent, folded, and wound at will, and can be moved and stretched in three-dimensional space without breaking. However, before the general LED flexible light strip leaves the factory, it usually only detects its on and off. The general operation is to turn o...
