铸铝合金外客，表面喷塑，防爆应急灯应急专用灯中正常照明灯和应急照明灯各自独立,适合安装条件许可的场所;照明应急两用灯, LED防爆应急灯正常照明和应急照明共用一个灯体,光源独立。防爆应急灯内装免维护镍镉电池组，在正常供电下自动充电，事故断电或停电时应急灯自动点亮。 钢管或电缆布线均可。LED防爆应急灯可根据用户要求设置试验按钮和指示灯具

Cast aluminum alloy foreign guests, surface spray, explosion-proof emergency light emergency special normal lighting and emergency lighting lamp independently, suitable for installation conditions permit places; emergency lighting LED lamp, emergency lamp normal lighting and emergency lighting share a lamp, light source independent. Emergency lamp the inner nickel cadmium battery, charging automatically in the normal power supply, power failure or power failure emergency automatic light. Steel pipe or cable wiring. LED emergency lamp can be set according to user requirements for test button and indicator

产品工作原理：

The working principle of the product:

防爆应急灯应急照明系统以自带电源独立控制型为主，正常电源接自普通照明供电回路中，平时对应急灯蓄电池充电，当正常电源切断时，备用电源（蓄电池）自动供电。这种形式的应急灯每个灯具内部都有变压、稳压、充电、逆变、蓄电池等大量的电子元器件，应急灯在使用、检修、故障时电池均需充放电。 另一种是集中电源集中控制型，应急灯具内无独立电源，正常照明电源故障时，由集中供电系统供电。在这种形式的应急照明系统中，所有灯具内部复杂的电子电路被省掉了，应急照明灯具与普通的灯具无异，集中供电系统设置在专用的房间内。

Emergency lighting emergency lamp with self-contained power supply independent control type, the normal power supply is connected with the self general lighting power supply circuit, usually corresponding emergency light battery charging, when the normal power supply is cut off, the standby power supply automatic power supply (battery). Emergency lights each lamp inside the form of electronic components, voltage regulator, transformer, inverter, battery charging and a lot of, emergency lamps in use, maintenance, fault when the battery needs charging and discharging. Another is to control the centralized power supply, no independent power supply for emergency lighting, lighting power supply fails, the centralized power supply system power supply. Emergency lighting system in this form, all the lamps and lanterns of complex electronic circuit are omitted, emergency lighting and general lighting is, centralized power supply system settings in a special room.

防爆灯具的分类：

Classification of explosion-proof lighting:

◆防爆灯具的防爆类别、级别与温度组别见国家标准规定。

Explosion proof type, level and temperature group the explosion-proof lamps meet national standard.

◆按防爆型式分为隔爆型、增安型、正压型、无火花型和粉尘防爆型共5种主要类型

◆ according to the type of protection for flameproof type, increased safety type, pressure type, no spark and dust explosion proof consists of 5 main types

◆按防触电保护型式可分为Ⅰ、Ⅱ、Ⅲ类。

◆ according to protection against electric shock type can be divided into I, II, III.

◆按外壳的防护等级分类：为了防护尘埃、固体异物和水进入灯腔内，触及或积集在带电部件上产生跳火、短路或破坏电气绝缘等危险，有多种外壳防护方式起到保护电气绝缘的作用。

◆ according to the protection grade classification shell: in order to prevent the dust, solid particles and water into the lamp cavity, touch or product set jump fire, short circuit or damage the electrical insulation of hazardous live parts, a variety of enclosure protection mode to protect the electrical insulation.

◆按灯具设计的支撑面材料分类：室内防爆灯具可能安装在许多属于普通可燃材料表面，如木质的墙和天花板，它们不允许防爆灯具安装表面的温度超过安全数值。

◆ according to the supporting surface material classification lamp design: indoor explosion-proof lamps may be installed on many belonging to the surface of ordinary combustible materials, such as wooden walls and ceilings, they do not allow the explosion-proof lamp mounting surface temperature exceeds the safety value.

◆按安装使用形式可分为固定式、可移式、携带式。

◆ according to installation and use can be divided into the form of fixed, mobile, portable.
