Q: What does "explosion proof lamp" mean? Why "explosion prevention"?: The explosion-proof lamp is used for dangerous places exist combustible gas and dust, to prevent the lamp may produce arc, spark ignition and high temperature surroundings of combustible gas and dust, so as to achieve the requirements of explosion-proof lamps

Q: camping lights, but this evening we used to have a stab in the neck Who hasWho has a good proposal? And it would be better to use that for a little longer: You can choose solar portable camping lights, use solar energy to charge, use only sunlight to recharge, and don't have to worry too much about camping lights without electricity. And the use of solar energy to clean energy supply, while camping, but also for the protection of nature to do its part.

Q: Can the current limiting resistor solve the problem?: As long as the voltage of the battery is in line with the voltage of the LED lamp, it can be used directly. The battery voltage is not more than 10%, or it can be used. More than 10%, the current limiting resistor should be added to solve the problem. What the power supply requires is the voltage to match, and what kind of battery can be used.

Q: where can I buy them? The key is genuine licensed?: The landlord, Taobao has a Tonman camp lamp, the current best use can be used when the camp lights, emergency flashlight, can charge mobile phone bag, whenever and wherever possible, with remote control function, with infrared function, as well as the SOS international distress signal, make the outdoor life safer.

Q: What are the three elements of an explosion proof lamp?: The three elements of explosion resistance refer to ignition point, combustion supporting gas and fuelExplosion proof refers to the force of the blast resistance and heat without loss can still work normally referred to as proof, prevent explosion will come from the three necessary conditions to consider, limit a necessary condition which limits the explosion. Select the corresponding explosion-proof instrument and explosion-proof type electrical equipment, the standard structure is: flameproof, increased security, positive pressure type, sand filled type, intrinsically safe and oil filled type.The explosion-proof lamp is used for dangerous places exist combustible gas and dust, to prevent the lamp may produce arc, spark ignition and high temperature surroundings of combustible gas and dust, so as to achieve the requirements of explosion-proof lamps. Also known as explosion-proof lamps, explosion-proof lighting. Different flammable gas mixture environment has different requirements for explosion proof grade and explosion proof form of explosion proof lamp.

Q: Performance characteristics of explosion proof lamp: 1, with T8LED lamp tube, light source efficient energy-saving, T8 fluorescent lamp than 50% energy saving.2, the unique design of light distribution, light type and angle precision control of the LED light source, to avoid light pollution and ineffective utilization of light; soft light, no glare, will not cause eye fatigue of workers, improve working efficiency.3 、 the shell is made of light aluminum alloy die-casting, and the surface is treated by high voltage electrostatic spraying.4. The interior of the lamp is provided with a connecting cavity, and a special connecting terminal is arranged. When the user installs, it can enter the line directly, and no connection box is needed, so that the installation is convenient.5, when the tube is changed, the lamp can be directly replaced by simply folding the lower cover.6, according to customer requirements, matching international famous brand T5 fluorescent tube, light efficiency, more in line with the actual lighting environment, compared with T8 fluorescent tube, power saving of about 30%.7, according to user requirements with emergency equipment, built-in light body, light weight, when the outside power failure, lamps automatically switch emergency lighting state.

Q: Summer camp is coming. Peaceful, sunny, solar power, camping light?: Dear, as energy-saving famous brand, peace, sunshine, power generation, solar camping lights, how can less? And it's absolutely affordable and easy to use. When you go out to travel and camp, don't forget to bring along a peaceful, power, solar camping light that lights your way and guides you in the direction of your trip.

Q: What are the functions of the multi function LED camping lamp?: You don't know which is the solar camping lamp, if new camping lights, with lighting and charging for small electronic products, the green solar energy into electricity, both energy saving and no need to worry about power depletion.

Q: A cone-shaped camping lamp with a bottom circumference of 62.8 cm and a height of 30 cm. How large is the lamp?: The circumference of a circle of radius r= = pi * 2 * 62.8 / 3.14 / 2=10C=2 PI RThe area of s=3.14*10*10=314 square circle radius x = PiS= PI R2The volume of =1/3 circular cone * * high V=314*30 / 3=3140 bottom areaLetter formula: V=1/3SH

Q: Who has a good recommendation? It would be better to use that for a longer time: I suggest you buy camping lights, recently I also bought one, very good use, and full of electricity after 70 hours
