Some people say that the more cores of the violet flashlight, the stronger the penetrating power, is this true or false?
It is also said that the more cores of the violet flashlight, the brighter it is, but what is going on? Don't worry, let's go together!
Some people say that the more cores, the stronger the penetration, which sounds a bit reasonable, after all, the more cores, the stronger the energy.
But in fact, the relationship between penetration and the number of cores is not so simple.
An increase in the number of cores can indeed lead to an increase in energy, but it also leads to the scattering of light and the accumulation of heat, which in turn reduces the penetration.
Therefore, the more cores the better, and the relationship between penetration and the number of cores has to be analyzed on a case-by-case basis.
Some people say that the more cores, the brighter they are, but that's not entirely true.
While it is true that an increase in the number of cores can lead to an increase in brightness, it is not the case that the more cores, the brighter it gets.
The relationship between brightness and the number of cores also has to take into account other factors, such as the beam angle of the flashlight, the convergence effect of the beam, and so on.
So, don't blindly pursue a large number of audits and ignore other factors!
The "core" of a violet flashlight usually refers to the number of lamp beads, rather than the key factor in determining its penetration or brightness.
The penetration and brightness of the UV flashlight are determined more by the following aspects:
1.Wavelength
The penetration of ultraviolet light is closely related to the wavelength, and in general, short-wave ultraviolet light (e.g., UVC) is not as penetrating as long-wave ultraviolet (e.g., UVA).
For violet flashlights, 365nm or 395nm wavelength ultraviolet light is mainly used for detection and identification purposes, and the penetration is not strong, but the shorter the wavelength, the stronger the penetration ability theoretically, but at the same time, it is also easier to be absorbed by the atmosphere and objects.
2.Power & Brightness
The brightness of the flashlight is mainly determined by the total power of the LED lamp beads it contains, that is, the greater the power of a single lamp bead or the greater the number of lamp beads and the greater the overall power, the brightness will theoretically be higher. But this does not equate to being more penetrating, because brightness and penetration are two different concepts.
3.Light source quality and design
In addition to the number and power of lamp beads, the quality of the light source (e.g., chip efficiency, packaging technology), and the design of the optical system (e.g., the efficiency of the reflector cup) also greatly affect the actual brightness and irradiation effect of the flashlight.
Therefore, the number of lamp beads of the violet flashlight is not the only factor that determines its penetration and brightness, but also needs to comprehensively consider factors such as wavelength, power, light source quality and optical design.
In practical applications, such as those used to detect fluorescent agents or security labels, the focus is more on whether the specific wavelength band of ultraviolet light can excite fluorescence, rather than simply pursuing penetration or brightness.
In short, you have to consider various factors when choosing a purple flashlight, but don't blindly pursue more cores! Only in this way can you choose a purple flashlight with better performance to meet your actual needs.
