Is it better to use LED headlamps or LED flashlights in outdoor activities?

News Trade News2021-09-15 20:23:57

Headlamps and flashlights are two commonly used lighting tools in people’s outdoor activities, and the two products have their own uses. The flashlight is flexible and can be designed to illuminate a long distance. It is used for searching and is very good for path detection. However, fast exercises such as flashlight trail running are inconvenient and are not conducive to terrain such as climbing. The headlamps moving with the head can illuminate the road ahead for a long time, freeing hands to do other actions, but it is inconvenient to search, and there are not many designs that pay attention to focusing on long-range shooting. Let’s learn about the knowledge of headlamps and flashlights.

Let me talk about the LED flashlight first.

Since the advent of white light LEDs, LED flashlights have been born, but at the beginning, because of the low brightness and high cost of white light LEDs, such products have been in the "laboratory stage." The high prices make no one dare to care about them—a small amount of promotion. With the increase in the brightness of white LEDs and the reduction in costs, they have gradually entered the ranks of the masses.
Semiconductor lgy saving, I don't know how many ordinary light bulbs are. LED flashlights range from 1W to 5W per month. When it comes to energy-saving advantages, aside from flashlights, LED products currently marketed are between incandescent and fluorescent lamps in terms of energy consumption. , Is expected to catch up with fluorescent lamps in 2008. But it is absolutely environmentally friendly and pollution-free. Long lifespan is the recognized advantage of LEDs, but LEDs for flashlights on the market can be said to be mixed.
Advantages of LED flashlight:
1. The long service life of LEDs can generally reach more than 50,000 to 100,000 hours, which is 5 to 10 times longer than that of traditional tungsten filament lamps.
2. Cold light, low heat generation, will not damage the lamp holder, and high safety.
3. Fast reaction speed, impact resistance, good weather resistance, small size, easy to be small and lightweight.
4. Power saving, energy saving, low power consumption, green material.
5. The response speed is as fast as 1us (microseconds), and the safety can be improved without the need to warm the light.
6. Low voltage drive (voltage 1.8~4.0V) is safe.
Disadvantages of LED flashlight:
A fatal disadvantage of LED flashlights, low color rendering index! The color displayed under the LED illumination is not as true as that of an incandescent lamp. This should be analyzed from the spectral distribution, which is a technical problem and will not be repeated. There is another shortcoming, the light spot; due to the defects in the manufacturing process of the white light LED itself and the matching error with the reflector cup or lens, it is easy to cause the "yellow circle" problem. Some manufacturers do not consider the quality and cooperation of the components and completely copy the products of other manufacturers, flooding the market with poor-quality LED flashlights, seriously damaging the reputation of LEDs.

LED headlamps:

LED headlamps have a very popular name: light-emitting diodes. It is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light.
The heart of the LED is a semiconductor chip; one end of the chip is attached to a support, one end is the negative pole, and the other end is connected to the positive pole of the power supply so that the entire chip is encapsulated by epoxy resin. A semiconductor wafer consists of two parts, one is a P-type semiconductor, in which holes dominate, and the other end is an N-type semiconductor, where electrons are the main ones. But when these two semiconductors are connected, a P-N junction is formed between them.
When the current acts on the chip through the wire, the electrons will be pushed to the P area, where the electrons recombine with the holes, and then they will emit energy in the form of photons. This is the principle of the LED light-emitting light. The wavelength of light is also the color of light, which is determined by the material forming the P-N junction.

Advantages of led headlamps

1. Energy saving and environmental protection: the energy consumption of LED lamps is 1/20 of that of halogen lamps
2. Low cost and long lifespan: The lifespan of LED lights from well-known manufacturers can reach 100,000 hours, which means that basically your car can't be driven, but it is still on.
3. High brightness: The brightness is much higher than that of the halogen lamp, and the warning lamp used as the brake light has no pressure.of ordinary light bulb flashlights, but it has a long life. In terms of energy saving, I don't know how many ordinary light bulbs are. LED flashlights range from 1W to 5W per month. When it comes to energy-saving advantages, aside from flashlights, LED products currently marketed are between incandescent and fluorescent lamps in terms of energy consumption. , Is expected to catch up with fluorescent lamps in 2008. But it is absolutely environmentally friendly and pollution-free. Long lifespan is the recognized advantage of LEDs, but LEDs for flashlights on the market can be said to be mixed.

2. Cold light, low heat generation, will not damage the lamp holder, and high safety.
3. Fast reaction speed, impact resistance, good weather resistance, small size, easy to be small and lightweight.4. Powevoltage safety: LED, the first element used in electronics, only needs a DC voltage of 12V to light up, and there is no need to worry about the voltage of more than 20,000 xenon.
5. Instant light up no longer need the xenon lamp "will be turned on again," just use it anytime.
6. Small size of a single LED: This is the favorite of designers, it can be assembled into various favorites, and it is the favorite of lighting manufacturers.

Disadvantages of led headlamps

1. The heat dissipation problem, if the heat dissipation is not good, the life span will be greatly shortened.
2. The power saving of low-end LED lamps is still lower than that of energy-saving lamps (cold cathode tubes, CCFL).
3. The initial purchase cost is relatively high.
4. Due to the strong directivity of the LED light source, the special optical characteristics of the LED need to be considered in the design of the lamp.

Outdoor headlamp

The headlamp can illuminate the road ahead for a long time and free your hands to do other actions. According to different situations, such as poor visibility in dense fog or dark mountain trails shaded by dense forests, it can help if you only rely on the brightness of the flashlight to illuminate the road. It is very limited, and holding a flashlight will have a hand that cannot be free, and it may not respond well in emergency situations. Therefore, it is recommended to use headlamps for outdoor activities.

A flashlight is a hand-held lighting tool, no matter day or night, walking in rugged mountains or other places, and encountering ferocious beasts or gangsters, you can send out an alarm in advance to scare them away. Good people can use high pressure to attack beasts or gangsters during an attack or robbery to achieve personal self-defense. At the same time, the loud alarm will also call rescue personnel around.

Outdoor headlamps are lighting tools that stay on the head. The main feature is a lighting tool that frees hands. When we walk at night, if we hold a flashlight, we will have a hand that cannot be freed. In this way, we will not be able to deal with unexpected situations in time. Therefore, a good headlamp is what we have to have when we walk at night. By the same token, when we camp at night, wearing headlamps can free our hands to do more things. Therefore, it is better to choose headlamps for outdoor travel. Outdoor headlamps are very convenient to use.

Headlamps or flashlights are very important equipment, but the battery must be removed when not in use to avoid corrosion. A small number of headlamps are water-resistant or even water-resistant. If you think that waterproofing is very important, but this kind of waterproof bulbs, but it is best to be rain-proof, because you can't manipulate it in the wild weather; the headlamp holder needs to have a comfortable soft. Some of the pads are pen-shaped hanging around the ear; the switch of the lamp holder must be durable. Don't put it in the backpack; it will turn on by itself, waste electric energy or cause some problems. The switch design of the lamp holder is best to be a groove if you think If there is a problem during the journey, it is best to stick it tightly with a cloth, remove the bulb or remove the battery.
Headlamps are an important piece of equipment indispensable in outdoor activities, such as hiking at night, camping at night, and the chances of using outdoor headlamps are very high. There are many good headlamps suitable for outdoor activities; you can go here to choose a suitable outdoor headlamp:https://www.thrgo.com/products
