Chapter 318 The knowledge blind spot of outdoor flashlight? (seeking subscription)

"Like ordinary flashlights, they are all LED lights. This is a common law in the industry. No other light bulb surpasses it in brightness and energy consumption. It is a mainstream technology product with high precision, long range, and long life. The ordinary version costs between 10 and 50 yuan. The time varies, and the price of some high-end ones is more than 100."

"For example, Weichi is also one of the LEDs, but its light is more similar to sunlight, and it is the kind of soft white sunlight. This kind of beam is bright but does not hurt the eyes, so the price will be higher."

"For flashlights, the other is water resistance. The measurement data is IPX0-8. The higher the value, the better the water resistance. IPX-6 or above is enough. Any higher value is dedicated to underwater operations. It is cost-effective for ground use. Reduced because of its high value, judging waterproofness not only depends on the data, but also checks the internal and external materials and workmanship of the flashlight.”

"And... everyone, don't look at this flashlight as inconspicuous, in fact, there is a motherboard inside the flashlight."

Studio.

"Motherboard? Is there a motherboard in the flashlight?"

"I've only heard that computers and digital devices have motherboards, but I haven't heard that there are motherboards in flashlights."

"It seems that high-end flashlights all have motherboards."

"Motherboard? Is this thing useless?"

Li Yuan shook his head.

"Of course the motherboard is useful, and it is very useful! Outdoor flashlights have a certain degree of integration, otherwise they cannot have high power in a small size, just like some cycling flashlights, the motherboard will be installed. Its main function is to Whether there is a memory circuit and a protection circuit."

"Let's talk about range."

"Outdoors, the range of the flashlight is a very important thing."

"If we talk about Weichi's flashlight, the range may be the only shortcoming, but the so-called shortcoming has reached a distance of 100 meters."

Studio.

"100 meters is a bit short, isn't it?"

"Is 100 meters short? Is it okay?"

"In an outdoor flashlight, 100 meters is not very long."

"Want to grow? Look for infrared spotlights! That's long."

"It seems that the anchor is quite familiar with it. 100 meters is really not a long way to say."

"A professional tells you that 100 meters is enough."

Li Yuan nodded.

"That's right, 100 meters is really not a long range for an outdoor flashlight, and some can even reach 300 meters. Of course, being able to reach 300 meters naturally has its advantages."

"But... think about it, people's field of vision itself has a limit, and no matter how bright the night is, no matter how bright the flashlight in your hand is, how can it be possible to see the environment 300 meters away?"

"In other words... no matter how long the range of the flashlight is, it's just a gimmick. Of course, there are some specific ones, such as spotlights, which are used to transmit signals. In this way, 300 meters is still necessary."

"However, if you are blindly pursuing long... then it's better to simply buy a special signal light."

"Moreover, Weichi's light concentrating ability is quite good, which can be said to be one of the best among flashlights. In this way, the range will be relatively increased. What's even more amazing is that after turning the roller, it can also be adjusted to Another mode with better astigmatism performance, which is the mode I turned on initially, has a relatively large irradiation area."

"And...if I remember correctly, the fourth generation also added light dominance."

Studio.

"What is photodominance?"

"It seems that generally only high-end products such as rescue flashlights will have light dominant?"

"In layman's terms, it is the color of light."

"This is the first time I've heard of the term light dominant. Is there anything special about it?"

"Generally, flashlights with light-dominant light can be adjusted to white light, medium white light, and yellow light."

"Just like the white light just now, it is the beam used for daily use, while the neutral white light is used in dusty environments, mostly for rescue, or some heavy snow weather."

"The yellow light is specially used for rainy and foggy weather. This kind of flashlight has many uses outdoors and is quite versatile.

At this time, Hu Kai on the side had already turned his depression into surprise.

What Li Yuan said has obviously touched Hu Kai's blind spot of knowledge. It is only now that Hu Kai knows that there are so many rumors about such a flashlight.

Moreover, Hu Kai only learned about the many uses of the flashlight after listening to Li Yuan.

Li Yuan: "About outdoor flashlights, everyone must choose an outdoor flashlight that can automatically adjust the low brightness level as the battery drains. Only such a flashlight will not go out suddenly!"

"You must know that the outdoor light source is a very important thing, and it is also a kind of psychological support. Once the power is cut off because it is not discovered in time, even if there is no danger, it will greatly touch the user's psychology."

"Fortunately, ordinary outdoor flashlights now have this function, so you don't have to worry too much."

"The other one is that I know the softness of the flashlight I mentioned before. A good outdoor flashlight will not cause too much discomfort if it is directly exposed to the glasses for a short time, and it will not be too dazzling even if it shines on people walking towards you. "

"And the flashlight must avoid stroboscopic situations. Such flashlights are extremely harmful to human eyes, so some flashlights are also equipped with diffusers."

Studio.

"The anchor is right, there is indeed such a flashlight."

"Well, I still agree with what the anchor said. Many flashlights are now dazzling."

"A flashlight like that won't work, it's too much for your eyes!"

"How does the anchor know so much about the various skills of the flashlight?"

"Yeah, I'm wondering too, especially about this uncharged flashlight, it seems to be very familiar."

"No, he even knows the functions of each flashlight so well."

Li Yuan nodded.

"Well, outdoor sports cover a wide range. They not only have certain commonalities, but also have certain aspects of lighting tools because of different types of outdoor sports."

"For example, the search function requires a flashlight with high brightness and long-range exposure. When diving, a flashlight with good waterproof performance and strong pressure resistance is required."

"When hiking, you need better battery life."

"In addition to the functions mentioned above, there are actually many factors that need to be considered when buying a flashlight."

"For example, outdoor sports require lighting tools to be available at any time. If lighting tools with poor reliability fail to work at a critical moment, it can be quite fatal, and once a serious situation occurs, it is likely to cause life-threatening! "

"Therefore, it is very necessary to choose a reliable flashlight with good reputation."

"As I said before, the so-called waterproofness is actually one of the prerequisites for reliability."

"As I said before, the waterproof standard is IPX-6, and if it is above 8, it is naturally the best."
