LED Flashlight Color Temperature

Cangnan Younglite Electrical Co.,Ltd | Updated: Jul 13, 2017


LED flashlight basic principles: flashlight by the luminous body, battery, circuit, shell, reflective cup, circuit box, switch and other components, the basic principle is the current from the battery out, and then reach the circuit, through the circuit to adjust the voltage and current, and then output to the light Body, lighting lighting.

Luminous body flash with the power: LED flashlight, halogen lamp, LED Flashlight ordinary light bulb and xenon bulb (sub-tungsten wire filled with xenon and just filled with xenon HID), other flashlight is not commonly used in this light The

As for me here that the brightness of each LED unit unified lumen (Lumens) marked, LED Flashlight that is usually said that the luminous flux.

1, LED: Recently the most popular is the LED, and the Chinese full name is "light-emitting diodes", low-power LED are generally used in 1AA or 3AA, I do not say that, the power is too small, LED Flashlight home also Can, but the outdoor more than the difference, the main talk about the use of outdoor high-power more than 3W it, the main representative is currently the most popular US CREE LED, long life, according to the manufacturer data up to 100,000 hours.

LED color temperature: each type of LED, but also according to the different color temperature into different types such as Q5 have Q5WB, Q5WC, Q2 Q2WB, Q2WC, Q25A and so on.

Basic color temperature from 5000-10000K, LED Flashlight according to K value points WJ, WD, WC, WB, WA, etc., popular talk about the lower the color temperature is more yellow, the higher the more white.

(2) Q5WB, 8000K color temperature, white light slightly blue, because it looks brighter than WC (because WC compared to slightly under the yellow), the actual use of the luminometer to detect the brightness is the same, by most manufacturers The use of mass production flashlight, we buy most of the domestic manufacturers are high-power flashlight WB color temperature.

(3) Q25A, color temperature in the 4000K-4500K, LED Flashlight are warm white series, light color yellow, because the yellow penetration, more suitable for outdoor use. Speaking of LED here also talk about the ultra-high power LED, and just said that the 3W is the highest to 250 lumens, and now South Korea SSC P7LED also used in a large number of domestic LED flashlight, the current 2.8A, Up to 900 lumens, the current domestic is more mature is WF-900, the brightness is indeed high, super dazzling, is characterized by astigmatism is good, but the long-range is not very strong, after all, the depth of the lamp cup is limited;
