One, first said the difference and brightness, we are always asking certain businesses flashlight light not bright ah what is Q2 and so on, let more people ask scratching their heads, XXX business and XXX business that several of the Q5 who is more bright, coma, simply can not answer, so to explain. The first LED early 5MM and domestic straw hat, but in the flashlight jar had eliminated, is now the South Korean Seoul and then a few do, and do more is a brand of electric lamp. The N P Q R brand to distinguish the brightness grade, [...]

Basic requirements: working flashlight requirements of different working environment on the flashlight is different, according to different types of work, suggests that sellers in the purchase of LED torch. The utility model has the advantages of durability, power saving, high brightness, etc., and a typical green lighting source. Eyes are very sensitive to light LED flashlight, but not direct light. Good LED flashlight with a waterproof function, should pay attention to the purchase of astigmatism. Strong flashlight waterproof, good seismic performance, that is, resistance to fall. New battery power is not too much; in charge, according to the charging speed [...]

Let's first look at the structure of incandescent bulbs. "PR" is the most common flashlight lamp bulb. They have a contact metal base with a metal ring, a glass cover and a glass capsule containing a filament. The light bulb is the metal ring is fixed on the light, so it will not shift at the time of the collision, but it is possible to break or break the bulb filament. The double - needle bulb is a small glass capsule with a filament and two pins. This bulb is plugged into the socket and fixed on the socket. So [...]

Light efficiency energy saving. Imported new ultra-high brightness high-power LED solid-state light source, energy saving, high light efficiency, long service life, maintenance free, no subsequent cost of use. Three major functions. Increase anti-skid function: granular increase lamp surface friction, with anti-skid function, prevent palm sweating contact lamp slide. Increase health care function: granular contact palm different points, indirectly promote the palm parts of the blood circulation, help workers relieve fatigue, achieve health effects. Increase heat dissipation function: granular increase the heat dissipation area of the lamp, accelerate the heat generated in the process of lighting, effectively prolong the lamp life. [...]

The flashlight product is easy to do, it is difficult to do light flashlight. Whether traditional lighting companies or LED new light source enterprises, there is no certain loser and winner, which has nothing to do with the market economy and products, and ideas related. With the continuous development of the lighting industry, explosion-proof flashlight into the lighting market, LED flashlight from the initial stage of rapid development to the application stage at present, in the process of development, development of light LED flashlight lighting enterprises to real breakthrough innovation. LED flashlight in twenty-first Century as a new light source, [...]

1, head number, head number to moderate. Household generally do not exceed 12, the use of the battery in the 2 ~ 3 for good, and then a little big wave for other special needs can be determined according to their needs. Of course, high-power LED flashlight generally can not reach the number of 12. 2, welding, welding to prison. Each diodes are connected by welding on the circuit board, if the weld contact is not good, it may cause the bulb does not light or affect the whole service. 3, ordinary batteries, battery and lithium battery two, although the [...]

The AC power supply through a resistance capacitance step-down unit after this, signal display and a bridge rectifier, it is used to charge the battery, the switch, when the switch is open, closed ahead, a group of light emitting diode connected to the work below, this is due to the reverse cutting diode D5 check, above a group is not working; when the switch is closed due to backward, forward by D5, the two groups of light emitting diodes are given the same power and work. This is the flashlight can have two different light. The main role of D5 [...]

LED flashlight charging characteristicsRechargeable LED flashlight is a new flashlight with LED (light emitting diode) as light source. Because LED has high brightness, low power consumption, long life, small size and other characteristics, it is the ideal choice for portable lighting. LED principle is similar. But the difference is, LED is not through the electronic transitions inside the atom to emit light, but by applying a voltage across the PN junction LED, the PN junction itself in a level form (in fact, is a series of energy), then the electrons at this level and jump to the light emitting photons. [...]

Led flashlight is generally used 18650 lithium battery has become the mainstream, and the market explosion flashlight battery possession of the number of fake, generally divided into several categories: 1 false capacity: The 18650 China battery technology in the 2200 volume, and many vendors in order to attract consumers, the battery capacity up to 3000 or 3200 false capacity, deceive consumers, reap more benefits. 2 refurbished battery: Refurbished battery from abroad, disassemble the battery, then refurbished by some illegal channels, a false capacity, the tired battery is very dangerous, the consumer is carry on a timed explosives in the side, [...]

Flashlight need to check and test regularly, if found not use, need timely maintenance and processing. In the usual use of the state should pay attention to the use of bright flashlight instructions. The flashlight is a lighting tool but It is quite common for the explosion-proof torch for all of us, is a very strange thing. This article only talk about the flashlight maintenance methods and instructions. Urge the battery is full, it is best to use the second, this can let the flashlight battery lamp and prolongs the service life of the product! With the hand torch heat [...]

If there is a LED light is not bright, please follow the following methods for initial maintenance: First, determine the fault: unscrew the tail, with a battery cathode, with a metal scissors or tweezers, connecting the battery negative electrode and battery beside the flashlight body bare unoxidized part, to see if the light. If you can, is the flashlight switch, please check in step 3; if there is no light please check the circuit positions and circuit board connections are open welding or soldering welding, please re welding if you can solve the problem. Two, check the battery: battery power [...]
