1.This3535 940NM SMD IR LEDlamp bead can be applied to what areas of products?

Light beads can be used with surveillance cameras, medical beauty treatment products, wireless communications and other products.

2.LED infrared lamp bead voltage why is so low?

Because the LED infrared lamp bead is a near-infrared light-emitting element that converts electrical energy into light energy, its working principle is to convert electrical energy into light energy, thereby emitting infrared. Compared with ordinary LED lamp beads, LED infrared lamp beads have a shorter wavelength of light, so they require a lower operating voltage to work properly. In general, the working voltage of LED infrared lamp beads is usually about 1.4V.

3.What are the precautions for using infrared LED lamp beads?

Material handling: When handling materials, it is necessary to use the dehumidified material as soon as possible, and the remaining material should be sealed or placed in an environment with 10-40 degrees and humidity not exceeding 30%.

Welding process: During the welding process, the material can not be directly taken by hand, and sweat on the hand will cause optical pollution on the silicone surface, affecting the luminescence. In addition, hand squeezing can also lead to broken wires resulting in dead lights. Avoid rapid cooling during welding, avoid any form of mechanical force or excessive vibration in the case of infrared LED bead welding cooling, and do not bend the circuit board after welding.

LED lamp bead cleaning: Special care is needed when cleaning colloid with chemicals, because some chemicals damage the surface of the colloid and cause fading such as trichloroethylene, acetone, etc. It can be scrubbed and impregnated with ethanol at room temperature for no more than 3 minutes at any time.

4.Is the 940NM lamp bead visible in infrared light?

The light of the 940nm LED infrared night vision lamp has a peak light intensity of 940nm, which is farther away from visible light. Therefore, when the intensity of the light emitted by it reaches the visible long wavelength of 0 value, the minimum wavelength is higher than 760 nm, the human eye cannot see. Therefore, the 940nm lamp beads emit infrared light, rather than visible light.

5.The difference between 940NM lamp beads and 630NM lamp beads?

940nm lamp beads and 630nm lamp beads are a kind of LED lamp beads, but their wavelengths are different. The 940nm lamp beads have a wavelength of 940nm and are mainly used in night security monitoring, infrared temperature measurement and other fields, which can provide clear, non-dazzling lighting while maintaining low power consumption. The wavelength of 630nm lamp beads is 630 nanometers, which is mainly used for visible light LED lamp beads, which can be used in blue band, green band, yellow band and red band.

Therefore, the main difference between 940nm lamp beads and 630nm lamp beads is that their wavelengths are different and their application scenarios are different. Need to be selected according to the specific needs.
