深圳神火supfire为大家介绍下有关LED强光手电筒的知识

      LED强光手电筒用大功率单颗【或多颗并用】发光二极管作为发光源,普遍采用铝合金作为筒身材料,以26650、18650等充电锂电池及Cr123、C、AA、AAA等碱性干电池提供电能,用高效的微电脑芯片或线路板连接,发出超强光亮的照明工具!

 

  光源方面:品牌手电生产厂家都会采用原装进口美国大功率CREE发光源,CREE芯片性能稳定,光能转换效率高,而且质量比普通的国产LED芯片会好几倍,当然价格方面也相当于普通的十几至几百倍,同时随着人们对更加亮的视觉追求,CREE公司推出更高亮度级别的LED,从开始非常流行220流明的Q5到现在普遍使用410流明R5,部分使用到达800-1000流明CREE XM-L T6/U2。中低端品牌手电普遍使用国产LED,目前也有部分使用CREE系列光源,不过大多数为上海工厂代工,性能还是没有达到美国原产CREE!

 

  光杯方面:根据使用需求,目前普遍使用两种光杯,光面金属反光杯,光非常集中,能够通过光杯反射出更为完美的光斑,适合远距离照明,使用环境有狩猎、探险、;橘皮纹金属反光杯泛光效果好,通关过漫反射,照射的范围广且清晰,用于近距离照明。

 

  筒身材料:不同的铝材之间性能不同,也会造成很大的价格差距,

 

  品牌手电多采用最高级别的航空级铝合金T7075、T6061,此材料超耐腐蚀,耐撞击,且便于精密加工,有此材料做出的手电,外观非常精致、螺纹深切清晰,密封性能非常好,手感也非常好,是目前最好的铝材,不过价格有点贵!

 

  电池的选择:电池对手电的亮度和续航时间有很大影响,锂电电池能反复使用,且具有容量高等特点,具有更长的总体续航能力,且很大程度上节约成本,但不容易购买到,单次续航时间短,干电池能够更好的发挥大功率LED的功效,稳定性高,且单次使用的时间长,且容易购买到,但需要经常更换电池,成本有所增加,国外人普遍喜欢干电池,国内的朋友则多数都选择锂电池。

  这是CREE LED的参数,超过这个一般就是虚标了.

 

  现在Cree的LED已经发展到了S2的水平,具体的发光效率可以参加右边的图标,同时一些最初的参数列在下面:

 

  Q5 →350mA 亮度107-114 Lumens,最大电流1000mA(可达220-250lm

 

  Q4 →350mA 亮度100.4-107 Lumens,最大电流1000mA

 

  Q3 →350mA 亮度93.9-100.4 Lumens,700mA 亮度152.1-162.6 Lumens

 

  Q2→350mA 亮度87.4-93.9 Lumens,700mA 亮度141.6-152.1 Lumens

 

  P4 →350mA 亮度80.6-87.4 Lumens,700mA 亮度130.6-141.6 Lumens

 

  P3→350mA 亮度73.9-80.6 Lumens,700mA 亮度119.7-130.6 Lumens

HID超强光手电筒

超强光手电筒

  hid超强光手电筒为高强度气体放电手电筒,科技含量高,采用高科技将氙气灌入石英内管,再透过精密镇流器将12伏特电力瞬间提高至23000伏特,激发管内的氙电子游离,在两电极间形成一束超强电弧光持续发光,军用强光手电筒不但照得更亮、也照得更广,由于氙气所产生的超强白色电弧光近似于白昼的太阳光,同样功率的HID灯,亮度大约是钨丝卤素灯的3倍以上,可为各类企业和事业单位夜间(或在照明光源不佳情况下)处理各种突发事件、工程设备抢修、工矿勘探作业、渔船海上作业、轮船的货柜及船舱作业、铁路作业、夜间野外紧急抢修作业等提供安全、可靠的高亮度移动照明。

LED Flashlight High Power single [and] light-emitting diode as a light source, commonly used aluminum alloy as a Flashlight material or particles, 26650,18650 such as rechargeable lithium batteries and Cr123, C, AA, AAA alkaline dry batteries provide energy efficient the microcomputer chip or PCB connection, to issue super bright lighting tool!
 
Light source: the brand flashlight manufacturers will adopt the original imports of U.S. high-power CREE hair light source, CREE chip performance and stability, high efficiency of energy conversion, and the quality is several times more than ordinary domestic LED chip will, of course, price is also equivalent to ordinary ten a few to a few hundred times, 220 Lumen Q5 to 410 lumens R5, is now widely used and partially used from the start is very popular with people more bright visual pursuit, CREE has introduced a higher level of brightness LED reaches 800-1000 lumens CREE XM-L T6/U2. In the low-end brand flashlight universal use of domestic LED is also some use CREE series light source, but most of the OEM factory in Shanghai, the performance still does not meet U.S. origin CREE!
 
Optical glass: according to usage requirements, widespread use of two types of optical glass, glossy metal reflector cup, the light is very concentrated, reflecting a more perfect spot light cup, suitable for long distance illumination, hunting, exploration and use of the environment, ; orange peel metal reflector cup floodlight effect, diffuse reflectance clearance, irradiation of a wide range of clear for close range illumination.
 
Flashlight material: aluminum between performance can also cause a lot of the price gap,
 
Brand flashlights and more using the highest level of aircraft-grade aluminum T7075, T6061, this material is ultra-corrosion-resistant, impact-resistant, and easy precision machining, flashlight made of this material, appearance is very delicate, deep clear thread sealing performance is very good, feel very good, the best aluminum, but the price is a little expensive!
 
Battery options: have a great impact on the brightness and life of the battery rival electric, lithium battery can be used repeatedly, and has the capacity and high, has a longer overall endurance, the largely cost savings, but not easy to buy into single life is short, dry cells are better able to play the efficacy of high-power LED, high stability, and the single use of a long time, and easy to buy, but the batteries need to be changed frequently, the cost of an increase in foreign people in general like dry batteries, domestic friends most of them choose lithium battery.
cree led parameters
 
CREE LED parameters exceed the general vacuity.
 
Cree's LED is now developed to the level of the S2, the the specific luminous efficiency can participate in the right icon, at the same time some of the initial parameters are listed below:
 
Q5 → 350mA brightness 107-114 Lumens, maximum current of 1000mA (up to 220-250lm
 
Q4 → 350mA brightness 100.4-107 Lumens, maximum current of 1000mA
 
Q3 → 350mA brightness 93.9-100.4 Lumens, 700mA brightness 152.1-162.6 Lumens
 
Q2 → 350mA brightness 87.4-93.9 Lumens, 700mA brightness 141.6-152.1 Lumens
 
P4 → 350mA brightness 80.6-87.4 Lumens, 700mA brightness 130.6-141.6 Lumens
 
P3 → 350mA brightness 73.9-80.6 Lumens, 700mA brightness 119.7-130.6 Lumens
HID super light flashlight
 
Ultra-light flashlight
hid super light flashlight flashlight for high-intensity gas discharge, high technology content, the use of high-tech xenon gas into the quartz tube, and then 12 volts of electricity instantly raised to 23,000 volts through sophisticated ballast xenon electronic excitation tube free In between the two electrodes form a bunch of super arc light continued to glow, military flashlight light not only shone brighter, also illuminate the broader, due to the super white arc xenon light similar to daylight sunlight, the same power HID lights, the brightness is about 3 times more tungsten halogen handle all types of emergencies for all kinds of enterprises and institutions at night (or under poor lighting source), engineering equipment repair, mining and exploration operations, fishing boats offshore operations, ship container and cabin operations, rail operations, night wild emergency repair work is to provide a safe, reliable, high-brightness mobile lighting.
