Q:LED light resistance, I use flashlight LED lights plus resistors used in the 12V circuit can be used for a long time?
Your resistance value increases, the resistance value of 1K can be (but may be dark light)
Q:LED flashlight is too light, just a little, especially bright
The concentrator LED flashlight is commonly used: 1: lens: through the lens optical design strictly to light gathering characteristics: small size, good convergence effect, but limited in scope, only suitable for large divergence angle and luminous coreSmaller led.
Q:Can the LED flashlight battery be used on two 5 cell toy cars?
As long as the size and voltage are the same as those for battery 5.
Q:LED LENSER flashlight, okay?
Led-lenser is the representative of Zweibrueder company in the field of luminescence of most of the products on behalf of the brand, is dedicated to research and development, design, production and sales of various energy-saving lamps and electronic lighting products, products include flashlights, portable lamps, Home Furnishing decorative lamp, outdoor lighting, commercial lighting and other lighting products with high quality, by the German product quality supervision and strict procedures, the products are widely sold in Europe and the United States and Southeast asia.
Q:What are the parts of a LED flashlight?
The shell, including the shell, reflector bowl, switch, etc.!
Q:At present, the LED flashlight commonly used in the market, the built-in lead-acid battery is too bad, can use 4 nickel hydrogen rechargeable battery instead?
Its battery life is short, mainly due to charging circuit caused. At the same time, the lamp component is current limiting resistors, greatly influenced by voltage. The current limiting resistor is selected according to the 4V voltage. When the voltage becomes higher, lamp current will increase obviously. When used instead of 4 Ni MH battery when the battery voltage is 4.8V, current lamp is much greater than 4V, so the lamp of life is very short. At the same time, because the charging circuit design is very unreasonable, the battery life is also very short.
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:The LED light flashlight can give you light plant
Yes, but because it is used for lighting, the amount of red and blue will be insufficient, or set the special tube, the best growth effect!
Q:What about the high brightness of a flashlight? Bull LED? Or single head high power LED? That kind?
At present, there are still a lot of brightness need to be observed on the market. The main thing is to rely on your own eyes or measure together. However, in the case of the same total power (such as 1W), multiple small power heat generation will be greater than a single high-power heating capacity. The reason is very simple, now all the conductors are not super conductor, there are resistance, since the resistance, the efficiency of electricity will not fully utilize the 100%, will certainly have the energy loss in the heating wires above, so the more long more heat is inevitable.
Q:LED rechargeable flashlight, small table lamp
The voltage between the 2V-2.6V is the lead-acid battery.Voltage at 3.6V-4. Between the 2V is the lithium battery.Generally speaking, charging more than time will cause serious damage to the battery, because the low charger does not automatically protect the battery. So, it's better to press the instructions.The light of the rechargeable flashlight sometimes shakes, probably due to poor contact between the switches and other parts. It can be checked by itself.The battery that has just been charged has the highest voltage, so the light is brighter, and as the energy consumption, the voltage will gradually decrease, so the lights will dim. In low level lamps without a stabilizer, dimming is normal.
