01 Shell
First of all, in appearance, ordinary usb rechargeable led headlamp are structural design according to the internal parts and structure of the direct processing and production out, without the participation of designers, the appearance is not beautiful enough, not to mention ergonomic. The high-quality headlamp is designed by designers, beautiful appearance, reasonable layout, more comfortable and reasonable in wearing.
Secondly, ordinary headlamps are generally made of plastic, in the waterproof level will be very low, encountered in the rain to rain on the scrap. And quality headlamps are generally made of aluminum alloy, in waterproof generally deal with very good, can reach IP7/8, and waterproof in the structural design of the relative non-waterproof structure is much more complex, and must increase the waterproof accessories.
02 Brightness (beads)
The soul of usb rechargeable head lamp and flashlights lies in the light, and what determines the light is the lamp bead, and the lens or reflective device. Let’s start with the lamp bead, almost all general lighting tools will say their products with how awesome LED lamp beads. Audi because of the excellent optical technology is the netizen teased to buy lights to send the car “light factory”, it can be seen that the price of high-quality usb charge headlamp is not cheap, high-end lighting tools bead price is usually already on the market a few times the price of ordinary lighting tools, which is why high-quality lighting tools are brighter and farther away from the bright, the service life is longer! This is also the reason why high quality lighting tools are brighter, farther and last longer. We generally low-end products and high-end products lamp beads can be tens of times the difference between the lamp beads.
03Brightness (lens or reflective device)
Lens or reflective device exists in the sense of controlling the dispersion of light, the general flashlight will have these two configurations.
There is an image of the analogy is: the reflector is a direct reflection of the light source, in this case there will be more or less leakage of some of the fish did not go through the reflection of the direct run out, while the lens is the light emitted by the source of all the light are swallowed, digested and then spit it out without wasting a trace of the light source.
Transparent plastic plate, the reflector surface of the lamp head is not flat and delicate enough, so the light spot is also fuzzy, even if the light is turned on to the high gear out of the light is scattered, and low brightness.
The light reflector will be concentrated light gathered, light reflector is special because it is one of the best light control effect, how much light emitted by the light source, it can be fully absorbed, and then through the light cup of the internal structure of the light will be gathered, there is no trace of light leakage can escape.
This is one of the important parts of the high-end flashlight that can guarantee the luminous flux.
