摘要
Abstract
Radiation detection is one of the commonly used methods in non-destructive testing industry , and industrial X-ray film needs to have high blackness in order to keep the contrast ratio , so the film viewer needs high brightness to meet the assessment of high blackness film .This paper designed a kind of high power LED film viewer based on PT4207 driver, supplying by AC power , PWM dimming by capacitive touch input , and fan speed controlled by temperature automaticly .The film viewer uses high power LED as its light source , its brightness is adjustable to meet the assessment of different blackness level .With its high efficiency, long life, energy saving, environmental protection, easy operation, and other advantages, the film viewer has very high use value .关键词
