Explosion Proof LED Worklight, Exproof Portable LED Floodlight

Series Name: Night Hawk Series. 
Why we use " Night Hawk " , the animal name to name our lighting
Night hawks are keen audition and visual, light feathers, silent flight, fast convolute and gliding in the sky.
Model No.: EX-NIH30
Ex Mark: Ex d IIC T6 Gb; for Zone 1&21, Zone2&22
Power Range: dimmable from 0-30W
Highlights: dimmable, indicator, chargeable battery, magnetic
The worklights are 0-30W stepless dimming, with built-in battery charging 6-8 hours, the electric discharge 4 hours in 30W, 6 hours in 20W, and 10 hours in 10W.

Applicaition
Suitable for emergency lighting such as power construction and maintenance, transformer substation repair, etc.

Portable LED floodlight features
1. Aluminum PCB: Adopt efficient heat dissipation metal matrix aluminum base copper clad laminate.
Excellent thermal conductivity properties, reduce module operating temperature, prolong lifespan, increase power density and reliability. At the same time, the aluminum plate are directly attached to the shell, evenly distributed in the periphery, so that the heat path is shorter and the thermal performance is higher.
 
We adopt professional reflow soldering paste technology for LEDs, which are more effectively safeguard the reliability of the light source.

2. Light source: Adopt high brightness OSRAM LED as light source, the light efficiency up to 140lm per watt, and long lifespan more than 50,000 hours.

3. Transparency:Tempered glass, in strict accordance with the explosion-proof electrical products of transparent glass impact resistance test, the thickness of surface cover glass is 8 mm, resistance to impact is 4 joule in the condition which absence of any protection.
High-performance transparent materials, effectively improve the light output efficiency, the light transmittance more than 90%.

4. Battery: Adopt UL approved Samsung battery. High energy memory-free battery, good performance of charge and discharge, big capacity, low self-discharge rate, economical and environment friendly. Can ensure more than 500 times charging and discharging cycle.

5. Lamp housing material: Currently, most of the common lamps are made of die-casting aluminum(ADC12), while our products adopt extruded aluminum(6063-T5 harden). The thermal conductivity of ADC12 die-casting aluminum is 96.2(W/m.K), while the extruded aluminum(6063) is 209(W/ m.K), more than 2 times of die-casting aluminum. About the copper content, die-casting aluminum(ADC12) is (1.5 to 3.5)%, but extruded aluminum only 0.1%, therefore named copper-free aluminum, it have stronger corrosion resistance performance, could be used in humid marine environment and corrosive atmospheres.
 
The lamp housing surface adopt hard anodized treatment, compared to spraying, the adhesion is stronger, effectively improve the corrosion resistance, abrasion resistance, weatherability. The color could maintain fullness in harsh environments, and it's not easy to scratches, paint chips and so on.

Overall Impression of Exproof LED worklight
1. The overall impression of the housing: The professional shape design are based on the investigation of customer requirement, independent research and development. Compared to cool color traditional lamps, the golden housing appears exquisite and delicate. Stepless dimming, freely convert the brightness by turn the knob. According to the operational need, the beam angle could be adjust in 360 degree, to achieve light ray aiming. Humanized pillar design, a variety of ways to carry such as handheld and lay. With battery indicator, we can monitor the electric quantity of battery at any time.

2. Derating design: considering the product could be normally used for extreme temperature environment of -25~+55ºC, on the selection and design of product components, we set aside enough margin, to guarantee the reliability and longevity of the products.

Reasons of why Night Hawk series worklight meet flame-proof form
Ex-Mark: EX d IIC T6 Gb. When work at the hazardous location where presence of flammable gas and dust, it can prevent arcing, sparks and heat generated inside the lamp which may ignite the combustible gas and dust in surrounding environment, thereby to achieve the purpose of explosion proof.

a. Thread design, set screws, which can limit the flammable sources such as air and concentration.
Thread using debit 5 to 8, and in strict accordance with the precision thread standard ISO 6g6H, have long thread length.

b. The cover glass using glue sealing, thickness with 10mm. Inside length more than 13mm (more than  actual requirements which is 12.5mm), with less than 0.15mm, limit explosion sources, straight mouth joints.

Explanation of Ex mark
EX d: flameproof
IIC T6: nitric acid, ethyl ester
T6: gas ignite temperature more than 85ºC, allowed highest surface temperature equal or less than 85ºC 
Gb: equipment protection level
