Made according to the standard attachment 14of ISAO and CAAC(commercial airpori night portable lamp universal technical condition) and passed the testing of Shanghai measurement testing research institute. The properties are: Adopt imported Osram bulb,long service life,high light,low consumption:average life of each bulb is more than 2000 hours,6or 7 bulbs inside,more than 6 years comperhensive life. Adopt advanced programmed PWM technology,under the computer control:it can produce red flash of 300cd.Because of the special flash mode,the life extended greatly,the special flash mode,the life extended greatly,the peak value flash strength reaches 200cd and more. The lamp flash period uses PIC which is adjustable. The usual period is 4 seconds on and 4 seconds off. Automatic exchange;there is a lamp composed of 6 or 7 bulbs,oen bulb works in normal times and the bulb can be exchanged automatically if it is out of order.It has two modes to control the synchronized flash Common one:adopt centralized control box to make several lamps flash at the same time. Intelligent one:adopt hand in hand communication mode and the synchronized communication wire to make several lamps flash at the same time, without considering of the number light_operated switch automation: Common one:hand control;the switch controls the centralized control box,day off,night on. hand control;adopt light control or time control for the centralized control box,day off,night on. Intelligent one;automatic light control,day off,night on. The lamp base found by the aluminum alloy,the surface is sprayed with plastic power;the paint layer has good attachment property and all the revealed parts uses the stainless steel material,and the lamp cover uses anti-temperature glass lens of good spotlight property and radiation distance.
