Laser lamps are used in buildings, parks, squares, theaters, etc., the use of laser beams of non-dispersive, can attract people's attention as far as a few kilometers away from the laser issued by the point has also become the focus of attention. Let's take a look at the following laser light hazards and safe use and other information.
A, laser light hazard
Laser light show, although good-looking, but also must remember not to look at a long time, because a long time to look at the laser light, the damage to the eyes is great.
Laser is also light, but the brightness is larger than the parallelism is good. The damage to the human eye is produced from these two points, the most critical or parallelism.
With a piece of paper blocking the laser power meter, leaving only a small hole of about 3 mm in diameter, around noon went out to measure the power of the sun - the most sensitive gears have no response, that is to say, the sun's diameter of 3 millimeters, and even 0.1 milliwatts are less than. Lasers, on the other hand, can easily be tens or hundreds of milliwatts.
Our eyes are also a lens imaging system like a camera. When parallel light is incident on the eye, as long as we're not looking at a very close object at the time, the light beam will be concentrated to a point on the retina. The laser light is already very bright, and if it converges a little bit, it will burn the retina.
However, the stage lighting commonly used on the green laser light on the human eye damage exists, like stage lasers emitting low-power laser on the human eye damage is cumulative, mostly irreversible, do not look more. Even if the laser pointer power is not greater than 5 milliwatts of power, as harmful to people.
Two, the safe use of laser
(a) laser safety instructions :
1, the laser must not at any time point to their own eyes or the eyes of others, even if the laser is turned off in the case of the possibility of mistakenly open.
2, the laser must not irradiate any reflective surface or smooth surface, the laser is extremely reflective, when irradiated to the reflective surface will produce reflection, if it happens to irradiate the human eye, can lead to injury.
3, the laser is not a toy, can not be given to children, intellectual incompleteness, the characteristics of the laser does not understand the use of people, in this case, very easy to lead to injury.
4, the use of lasers should wear special goggles, for invisible lasers, this point is particularly important.
5, the laser can not be illuminated to the vehicle, the aircraft and other vehicles with people.
6, to pay attention to the safety of the laser battery, to prevent others from disassembling the battery caused by short-circuit combustion or battery explosion.
7, not in public with the laser to entertain others.
8, high-power lasers, especially with burning laser, must be safe to use, not common sense irradiation of themselves or others, not common sense ignition of flammable and explosive substances.
(2) the general use of civil level laser :
1, general instructions. For example, workshops, warehouses, large venues, construction sites and so on. General use of low-power laser pointer.
2, outdoor signaling instructions. For example, outdoor at night, available laser as a signal. Particularly used in donkeys hiking and so on, can be used as mutual illumination signal. If you lose your way, you can use it to signal for help.3: Parallel Guidance. Laser for light polymerization light, short distance laser straight, its light can be used as a horizontal guide.
4: general entertainment hobby. Especially high-power laser, mostly used for entertainment. Prefer its light obviously, or like its burning.
(3) Specific to the actual use of laser products, should pay attention to the following aspects :
1, the laser is dangerous, do not irradiate the human body or animals with the laser, do not use the laser to entertain others, do not use the laser to irradiate the vehicles, airplanes and other means of transportation. Please do not use laser in any occasion where laser is prohibited, so as not to cause harm to yourself and others.
2, pay attention to the battery positive and negative poles loaded correctly, load the reverse may burn the circuit or the luminous body.
3, a continuous lighting time control in the corresponding time, low-power laser in 3 minutes, high-power laser control in half a minute to 1 minute. Specific to the merchant proposal shall prevail.
4, pay attention to the use of the environment, do not use in a dusty or foggy heavy occasions, to avoid debris sticking in the export glass surface, affecting the quality of the spot.
5, the laser is not used for a long time should be removed from the battery.
6, you can not disassemble the laser or battery and other related accessories, the resulting product problems and safety issues at their own risk.
7, after use should be placed in a place where children can not reach, so as not to cause accidental injury.
Laser lights have bright colors, high brightness, good directivity, long range, easy to control and other advantages, looks more magical dream feeling. For more information on the hazards of laser lights, please continue to pay attention to Tubaboo decoration network.
