ZYVF-L10型便携式LED工业射线底片观片灯
产品介绍
       ZYVF-L10型LED观片灯是针对JB/T4730-2005《承压设备无损检测》和GB/T 19802-2005《工业射线照相底片观片灯》新的标准研制的新产品。
光源采用大功率的LED面光源，使其在高亮度下，依旧具备极高的均匀度，且理论工作寿命在50，000小时以上，是现有工业射线底片观片灯的更新换代产品。
       此外，还具有造型美观、结构合理、光线均匀稳定、使用可靠、携带方便、亮度可任意调节等特点，是目前理想的X射线照像底片观察灯具。能广泛适用于机械、化工、航空、造船、锅炉、电力等单位射线照像底片的评定工作。便携坚固耐用的外观设计，使其极度适合在野外流动性的场合工作。观察屏材料采用日本三菱株式社生产的亚克力板，具有超越玻璃的透光性，良好的慢散射性能，并且持久耐用，不变形、不变色，可清晰地观察到在4.0D黑度底片上的微小缺陷，满足了日常使用的需求。
       该产品还根据人眼生理学的特点，限定LED的色温在8000K左右，不刺眼，即使长时间地观看，眼睛也不易疲劳。采用针对LED观片灯而设计的恒流驱动方式，更大程度上保证了LED的正常工作，从而达到延长寿命的目的。低压电子脉宽调制方式的亮度无级调光，进一步保障了使用者的安全，具备脚踏模式和手动模式，满足不同工作习惯，节能环保。

ZYVF-L10型便携式LED工业射线底片观片灯
Product Introduction  
ZYVF-L10 LED film viewer is a new series product that followed by the new standard of <> GB/T 19802-2005<< Industrial radiography published film view pieces lamp>>.
The light source adopts high power LED light source surface to make it keep a real high degree of uniformity in high lighten 。Theoretical work life is more than 50,000 hours; it is the products from the existing industrial radiographic film.

 Besides, it has Beautiful shape, reasonable structure, stable light, reliable easy to carry, brightness can be arbitrary regulate. it ‘s the ideal X rays photographic plates observation lamps lanterns which can be used widely in Unit radiographic evaluation of Mechanical , chemical, l aviation , shipbuilding, boiler power area. Portable durable appearance design, make its extremely suitable fthe occasion of liquidity in the field work. Observe screen material from Japan Mitsubishi is used plant type club production of acrylic, has surmounted glass pervious to light quality, good performance, slow scattering long durability deformation discoloration, can be observed clearly in 4.0 D black fthe film on the small defects, meet the demof daily use. The product also according to theacteristics of the human eye physiology, limit the LED coltemperature in 8000 K so, not dazzling, even if long time to watch, the eye also not easy fatigue. In view of the LED lights design of the constant current driving way, more degree ensure the normal work of LED, so as to achieve the purpose of life extension. Low voltage electronic pulse width modulation method adjustment the light to ensure the security of the user. It has feet mode manual mode, meet different work habit, conserve energy protect environment.

 Different from traditional view pieces the advantages of light rays
1the design is simple the product is portable.
2 it can be used in indolaboratory.
3 View pieces density > 4.0 D (without focusing ring
4 Low thermal noise no damage to film
5 Very low power loss
6 The working life over 50000 hours, the power supply 170 ~ 250 V/AC 47 to 63 Hz AC
7 Safe, fully enclosed heat insulation structure, with DC24V fan heat dissipation.
8 The design is novel, trendy
