LED light source photochemical reaction appearance

The utility model relates to a LED light source photochemical reaction appearance, a serial communication port, including casing, LED light source, heat abstractor and apron, LED light source, heat abstractor and apron set up in in the casing, be equipped with at least one test tube position on the apron, the LED light source encircle set up in around the test tube position. The utility model provides LED light source photochemical reaction appearance, can improve experimental efficiency, reduce cost, LED is longe -lived, and is luminous even, the light decay is little, the test tube position all has rather than the magnetic stirring device that corresponds, utilizes long -time scientific research experiment, the LED light source can conveniently separate with the magnetic stirring device, does benefit to the light source of the different wave bands of convenient change.
