Q:Strong flashlight, LED lamp positive and negative poles, how to distinguish?: See the disk inside the LED - - the thin line above the disk is +

Q:The sea king Diaoguang flashlight JW7200 can be converted into a LED light it: JW7200 applies to railways, electric power industry, oil field, metallurgy, troops, petrochemical enterprises and other flammable and explosive places of class II, class T1-T6, group C, zone 1, District 2, underwater and other work site to provide mobile lighting. Protection grade IP65 anticorrosion grade: WF2.

Q:High power flashlight LED lamp is 1W, want to use mobile phone battery when 4.2V is connected to electric drums!: As for the big resistance associated with rated voltage of LED bulb. Assuming the 3.3V, the 1W current is about 0.3A.The voltage on the resistor is 4.2-3.3=0.9V, the current is 0.3A, and the series resistance is about 0.9/0.3=3 ohms.Assuming LED lamp voltage rated voltage is 3V, current of about 0.33A 1W.Resistor voltage is 4.2-3=1.2V, current 0.33A, about 1.2/0.33 = 3.64 OHM Series resistor.

Q:Which brand is LED flashlight good? Recommend it: Look at the battery, a common battery and lithium battery two, although the lithium rechargeable batteries, but the low life of about 2 years, LED's life expectancy of about 10 years, can choose according to the actual situation.

Q:What about LED flashlights and AMC7135, and a better, more practical IC?: Product reputation, as one of the domestic high-end products manufacturers There remained but a single one. flashlight, we have been engaged in precision machining of titanium (titanium metal factory area, fine processing of a handful of domestic titanium metal) as long as it is, we do, someone might ask, what is only titanium.

Q:Paili de LED flashlight in "180 lumens," what do you mean?: Lumen, a measure of light intensity, refers to a measure of light energy per unit area. Said: paili de LED flashlight can reach 180 lumens, its meaning is in the distance, the flashlight can achieve light intensity. The significance of this indicator is not very large, because if the spotlight is better, the light intensity of the spotlight should be high, otherwise the spotlight will be larger and the light intensity will be lower. It does not represent a true luminance indicator.

Q:LED flashlight and laser flashlight is the same? And why are laser flashlights green and blue, and no white ones?: Dissimilarity。 In addition to the composition of light is not the same, the laser transmission process light path is not easy to diffuse, light energy is more concentrated, you can pass farther.

Q:What are the LED flashlight bulb?: Flashlight with beads. What do you look at the level slightly, generally cheapest are those with high imitation LED lamp, high power flashlight better are mainly domestic large power LED lamp is cheap, the quality is good, the use of imported LED, such as the U.S. CREE, South Korea's SSC, as well as Nichia LED and so on.

Q:How much is the working voltage of 5W's bright flashlight LED?: The 18650 common market mostly fake copycat lithium-ion batteries, the quality is poor, mostly for the flashlight, may not have the best internal protection plate, for better quality of the goods, the battery should use lithium battery charger. Charging with 5V is not appropriate.

Q:What's the resistance on the LED flashlight?: If 3 heads (3 LEDs), the operating current is 3*20mA=60mA=0.06A, the voltage at both ends of the resistor is 3-0.7=2.1V, so the resistance power is 2.1V*0.06A=0.136W., so the power of the resistor is 1/4W.
