There is a patterned glass sheet in front of the light bulb of the flashlight. The light can only pass through the hollow part, which naturally forms a special pattern. You can imagine that a star shape is carved out on a piece of opaque cardboard. Then cover it in front of the lampshade of…
The blue and green light of the laser flashlight corresponds to light with wavelengths of 473nm and 532nm, respectively. 1. Classification 1. Divided by wavelength It can be divided into red light 635-650nm, green light 532nm, orange light 593.5nm, blue-violet 405-445nm (445nm is already near blue light), pure blue light 473nm, and invisible infrared 808nm,…
The light path of the light emitted by the light source is concentrated in one direction, which is parallel light. At the same time, as long as the intensity of the light source is strong enough, it becomes this kind of laser. Red light is used because red light has the shortest wavelength among visible…
Explosion-proof flashlights for firefighting are not much different from explosion-proof flashlights used in other environments. All have an explosion-proof function. Mainly considering the special working environment of firefighting, fire-proof explosion-proof flashlight manufacturers perfectly match explosion-proof flashlights and clips and can be used with helmets, which solves the firefighter’s hands and maximizes work efficiency.
1. Check if the charger is damaged, plug in the power supply, and see if the indicator light of the charger is on. Second, check whether the battery is damaged, replace it with a new battery to verify. Third, check whether the lamp beads are damaged Fourth, check whether the explosion-proof flashlight is malfunctioning due…
Explosion-proof flashlights are used for firefighting, electric power, industrial and mining enterprises, and other flammable and explosive places to provide mobile lighting. It is very suitable for various field operations, such as geological exploration, tourism exploration, border patrol, coastal defense patrol, rescue, and disaster relief, field operations, tunnel operations, airport inspections, railway inspections, archaeology and…
Lithium battery, Ni-MH battery, No. 5 or No. 7.
I personally think that lithium batteries are better and can be recharged.
Ni-MH batteries are not as good as lithium batteries and can also be charged.
No. 5 and No. 7 batteries are generally known, so I won’t answer them, and they cannot be charged.
1. The light source adopts high-power high-brightness white LED, which consumes less energy and has a service life of up to 100,000 hours; the reflector adopts high-tech surface treatment technology with high reflective efficiency, the illumination distance of the lamp can reach more than 50 meters, and the visible distance can reach 5000 More than…
In the beginning, charge for 12 hours, and the battery needs to be fully charged for the first 3 times. Rechargeable flashlights are generally lead batteries, which can basically be fully charged in four or five hours. If it is a lithium battery, it is recommended to be fully charged. Don’t let the flashlight recharge…
1. Wipe dry with a soft cloth immediately after using the flashlight to prevent use in rain or snow or the penetration of moisture and hand sweat. Otherwise, the coating of the flashlight is easy to fall off or rust. 2. Do not put the flashlight on the hot Kang or beside the stove at…
