- Q:Now most LED flashlights are using resistance to drop voltage charging, waste a lot of energy, why manufacturers like to use?
- Mainly low cost, simple, can only be suitable for small lead-acid batteries. Disadvantages, power consumption, low efficiency of poor, can only be combined.
- Q:How many lumens does high light flashlight need?
- I am doing titanium lighting flashlight, the flashlight irradiation effect is relatively strong, mainly C10 flashlight with 800 lumens single chip CREE XML T6 LED, close the pan light intensity, long distance focusing, pavement irradiation effect is great, and the first choice is the outdoor riding at night. 18650 hours straight, with another T6 LED small size, brightness super awesome, you can exchange.
- Q:What does CREE flashlight mean? Do you have a CREE flashlight?
- The irradiation effect of strong flashlight, C10 flashlight is equipped with 800 lumens XML T6 LED single chip CREE, close the pan light intensity, long distance focusing, pavement irradiation effect is great, and the first choice is the outdoor riding at night. 18650 hours straight, otherwise T6 LED with small size, brightness super awesome,. Hope to adopt.
- Q:Buy a few flashlight LED lamp, directly connected to the 5V electric heating lamp why. How to solve?.
- The general electric LED lamp with voltage does not exceed 4.2V, because 18650 of the full battery voltage is 4.2V, voltage to 3.8V protection to prevent the excessive discharge of the battery. The heating lamp is normal, the more heat generating power is also bright brightness. So the LED lamp equipped with aluminum substrate and the copper circuit warehouse to heat.
- Q:When the LED flashlight is charged, the bulb turns dark, the light is dim, and the spot is a little yellow. It has been charged for 5 hours
- Probably when charging voltage is very high, then open the lamp on the current will greatly exceed the rated value, the lamp aging in a short period of time, the ablation of fluorescent powder produced spot, using terminology that is a short time attenuation increase, belongs to the permanent damage can not be repaired, only the replacement, but according to this phenomenon look, there may be a battery performance has been poor, does not rule out the charge line element anomaly
- Q:Flashlight long shots selected focus or zoom well
- To the long-range, of course, zoom is good, you can shoot very far, but also very bright.
- Q:The market is generally concentrated LED flashlight, the probe has to do astigmatism flashlight?
- Their home TK737 focus flashlight can focus, but also astigmatism practical.
- Q:Just bought Led flashlight flashlight, 5 hours charging 9 hours of electricity, and now there is no electricity, but the charger shows full power, but it is not bright, what is the matter?
- The anode material of lithium ion battery is cobalt oxide lithium, and the negative electrode is carbon. When charging the battery, lithium ion battery has generated cathode, lithium ion tea eng movement through the electrolyte to the cathode. As a negative electrode, the carbon presents a layered structure, and it has many micropores. The lithium ion that reaches the negative electrode is embedded into the micropores of the carbon layer, and the more lithium ions are embedded, the higher the charging capacity. Similarly, when the party discharges the battery (that is, we use the battery), the lithium ions embedded in the negative carbon layer emerge and move back to the positive electrode. The more lithium ion goes back to the positive electrode, the higher the discharge capacity. What we usually refer to as battery capacity is the discharge capacity.
- Q:What is the current when charging an ordinary LED flashlight?
- Ordinary LED flashlight rechargeable battery is nickel metal hydride battery (1.2V), and there is a lithium battery, voltage 2.45-4.20V, models have 14500, 16340, 18650, etc., charging current of about 200mA.
- Q:Flashlight LED one super bright, how many volts?
- See the lamp and brand. The most commonly used CREE L2 series are the most 3V, the CREE R5 series, up to 1.5V. These brands can find accurate parameters on the official website of LED.
