There are no essential differences between tactical flashlights and common flashlights on the principle and structure, but the tactical flashlight can adapt in various harsh environments under the conditions of use requirement, therefore its performance, compared with ordinary flashlight, in various environmental factors and conditions should be much better. Tactical flashlights are mainly made for military and law enforcement, their roles include: Fighting Because of the tactical flashlight illumination and color temperature are very high, they have a strong visual effects. to illuminate for fighting in the dark, will direct light each other's eyes, in order to make the other [...]

Different people may take high power differently, for example, some may think flashlights that can produce 200 lumen light are high power flashlight; while some may think that can emit 500 lumen light are high power. What is your opinion? No matter what high power refers to, high power flashlights are quite bright. In the market, most high power flashlights?are made of aluminum, do you know why? Here, I will walk you through the reasons. For dissipating heat. If the flashlight is high power, the brighter the light is, the more power it consumes, and more heat it generated. If [...]

Though now, many LED flashlights are made of metal, for example stainless steel, aluminum alloy, etc., and are very durable, wearable, you also need to maintain them often.?Since many new users do not know how to maintain flashlight, here, Tank007 editor will share you some tips about?how to maintain led flashlight. First, the battery 1. As the power source of the flashlight, battery is very important.

In LED application problems and solutions In current practice, the problems existing in the high power LED is mainly manifested in the following aspects: 1. To ensure that LED to poor working conditions and the cognition to the power supply technical, product on the power supply fault emerge in endlessly. 2. The application of LED street lamp today practical road concept is not clear, blind and high power gas discharge lamp "rival" regardless of the cost of production of large power LED street light, cause not practical expensive street light products to promote. 3. Feel inadequate to road lighting requirement, [...]

The principle of small family indoor lamps and lanterns chooses The principle of small family indoor lamps and lanterns choice: Reduction principle: lamp act the role ofing should have the effect that make the finishing point in the room. Too too complex modelling, multifarious design and color, are not suitable for simple design of the room. : convenient principle major person has experienced change the awkwardness that sucks dome light bulb: stepping on a table, stepping a chair, hold one's head high 90 degrees, carry double arm overdoes 2.5 meters tall taller even ceiling. Replacement bulbs must consider when choosing [...]

The remarkable high sharp LED dimming technology The volt-ampere characteristics of leds So-called volt-ampere characteristic of LED, LED p-n junction is through the () may refer to the LED revolution, revolution, change characteristics of current with voltage, on the oscilloscope can be very vividly display the change (as shown in figure 1), a complete volt-ampere curve including the forward and reverse characteristics. Normally, reverse characteristic curve is relatively steep, when the voltage exceeds a certain threshold, the current will be exponential rise, thus LED p-n junction breakdown. And the LED forward voltage is determined by the forward current. From the [...]

"Three ask a" comprehensive knowledge decryption LED chip 1, what is the LED chip manufacturing process? LED chip manufacturing is mainly in order to make effective and reliable low ohmic contact electrode, and can meet the minimum pressure drop between can contact materials and provide the pressure pad of welding line, at the same time the light as much as possible. Crossing the membrane process generally by vacuum evaporation method, the main in 1.33 x 10? 4 pa under high vacuum, resistance heating or electron beam bombardment melt material, heating method and under low pressure into a metal vapor deposition [...]

The LED application Who let it return to the light quality? Level with the lighting of LED light source in material technology, manufacturing technology, the application of mature, one day after some years based on the environmental problem is increasingly serious, disorderly economic development, all countries in the world energy conservation and emissions reduction under the pressure of reality, the LED lighting application was finally explosion point, by the deployment of the reason is not because the LED light have much good, but because of who I am LED energy saving, based on this, the government's policy guidance, the media, [...]

LED lights with considerations and parameters of choose and buy Now LED lights belt is one of indispensable to home lighting products, need to pay attention to when buy 6 elements. Leds with low because the threshold of the production, there are many factories and mills have the project, lead to the LED lamp and evil people mixed up with the market, the production of the product quality is uneven. Without the knowledge and experience are easy to be cheated to buy inferior lamp tape. But experienced people still have a way to identify, formal manufacturers of LED lights belt [...]

LED epitaxy growth process of the solution To explore the growth process of LED epitaxial wafer today, early in the era of integrated circuits, each of the 6? The epitaxial wafer on thousands of chips, now submicron line width of VLSI, each of the eight? On the epitaxial wafer can only complete YiLiangBaiGe large chips. Epitaxial wafer manufacturing is moving? Investment tens of billions, but it is all the basis of the electronics industry. Silicon column of grown up, you first need to put a high purity silicon ore in a furnace, and add predefined metal material, make the silicon [...]

LED lamp bead common problems and solutions 1, are the problems caused by power supply not normal: 01. Check the power supply power supply have a normal job, designator light had lit up, if there is no light up, please check the power supply have good connection; 02. Check to see if the lamp bead wire with power supply anode connection is good, is there a reverse phase, if you have the above problem, please correct connection. 2, LED lamp bead to the requirement of voltage: Nominal 3 v LED lamp bead, in fact, different color also have different requirements [...]
