产品特点 Features

1.壳体采用高强度合金铝一次性压铸成型，表面经高速抛丸清理后高压静电喷塑。外壳结构紧凑合理、材质密度高强度好、 防爆性能优良，表面塑粉附着力强具有良好的防腐能力，表面光洁，美观大方；
2.灯体在水平旋转360°，仰角 + 90°~ -60°内可调；
3.灯罩材质采用钢化玻璃，透光性好，反光罩经过严格的二次光学设计，并经过实际测试的验证，其采用高纯铝并经处理，反光率高，聚光性好；
4.有较强的防水性能，可用于石油平台及油轮船舶等场所。
5.电缆布线。
1.Shell made of high strength aluminum alloy casting off the surface after blast cleaning by high voltage electrostatic spray. Shell compact structure, high density material strength, Explosion-proof performance, the surface of plastic powder adhesion ability with good anti-corrosion, the surface smooth, elegant appearance;
2.It can be rotated 360°horizontally and adjusted in the range of +90°~ -60°.
3.Lamp housing is made of tempered glass with great transmittance,Focusing structure is in the lamp with Ⅱ type,and it can adjust the long distnce and short distance. The reflect should get special softwaredesign of distrbution for two times, and it can have the confirmation of actual test. After treating with high puity aluminum, it has great reflection and spotlight.
4.Using in the petroleum platform, tanker, ships and so on, has fine water proof function.
5.Wiring with cables.
