“The sky that rises is a boy's day. He used to dream under the stars....†This is the lyrics that Zheng Zhihua sang in the “Star Lights.†Today, those who dream in the light of stars The teenager has grown into a donkey who walks through the mountains. Here we borrow the lyrics of that year to describe the unattractive but indispensable stars in our outdoor equipment. From the current development of headlamp products, LED headlights are still quite powerful. From the latest PETZL-MYO XP and PRINCETON TEC-EOS. They all represent the current development trend of headlamps: high-power LED bulbs, that is, the power is about 1W (the new PRINCETON TEC APEX has reached 3W). Multi-mode, that is, by changing the voltage to adjust the lighting mode (change the way to adjust the light by increasing or decreasing the number of open bulbs). However, these improvements still do not break the inherent disadvantage of the lack of light penetration of LED cold light sources under complex climatic conditions. How will the headlight technology of the future develop, please wait and see. Compared with other outdoor equipment, headlights are one of the slower replacement upgrades. And its use frequency in equipment is quite high. Therefore, it is very important to maintain the good headlight performance at all times. To do this, the user must be required to develop good maintenance and usage habits during normal use. Based on my experience in outdoor activities, I mainly say two things that we need to pay attention to: 1, a reasonable use of methods In outdoor activities, more light is required for LED scattering when used in camps. In the state of climbing, hiking, etc., an incandescent lamp with long-range light is more needed. According to local conditions, users are required to apply different light patterns according to different environments in order to prevent unnecessary energy waste. 2, good maintenance habits The outdoor environment is complex and diverse, with both heavy rain and yellow sand. Poor use of the environment requires headlamp users to properly maintain the lamp body after each activity. For example, to clean the dirt attached to the surface; remove the battery before storage; avoid direct sunlight (preferably a cool and ventilated place) during storage to prevent damage to the headlamps caused by aging rubber and plastic materials.

In the city, we have become accustomed to the colorful nights. The dark night that is not visible to the people seems to be far away from the city. However, in the outdoor environment, this dark night is just like a common one. Behind the night are many unsafe hidden dangers, perhaps an unknown journey, perhaps an unknown danger. Because of this, the headlights become a must-have item for every person who participates in outdoor activities. Outdoors at night It can not only provide you with reliable lighting, but also make it very easy for you to free up your hands to do other things, such as climbing the rock wall safely while climbing; operating all kinds of equipment or maintaining the car calmly while driving and many more.
The current outdoor market headlamp products can be said to be exquisite and varied. From the price point of view, there are more than ten yuan of street goods in the domestic hardware market, and there are thousands of imported top brand headlight products. Said that both OEM OEM products, but also specialized in headlamp production of professional manufacturers of products. Although the market's products are mixed, but from the process technology point of view, the most basic is still incandescent and LED-based products The former was an absolute representation of headlamp lighting (especially for long-distance lighting) and the latter, with the continuous improvement of technology (especially high life and low energy consumption), is about to unify the trend of the arena and face different technologies. In the selection of the headlights, the user's needs are very important. Different uses should deal with different headlights. When buying, do not blindly listen to advertisements or choose from the level of price. Instead, analyze the headlight objectively. Performance and their own actual needs. Do not buy expensive, just buy suitable. In order to avoid unnecessary waste in performance.
From the light source, I called the light source of the incandescent lamp as a warm light source. Its principle is to use the inert gas inside the light bulb to work. Currently, the mainstream products on the market are mostly halogen bulb lamps. The incandescent lamp is more suitable for long-distance illumination (simple Described as a similar point of exposure), the color of the illuminated object is yellow, and the eyeball can easily identify the object under dark conditions. Therefore, when performing outdoor activities (especially hiking or climbing activities) at night, try to select the type of incandescent lamp. Headlights. LED light source can be called a cold light source. His principle is the use of current through the light-emitting diodes. LED light is more suitable for distance illumination (simple description is similar to surface illumination), the object being irradiated is whitish, It takes a certain amount of time for the eyeball to recognize the object under dark conditions. Since the LED emits scattered light, it is very suitable for use in camps, especially for low-intensity activities or long-line tourism activities where there is less nighttime activity.
Compared with the characteristics, the advantages and disadvantages of these two kinds of light sources are also very prominent. In simple terms, the advantages of incandescent lamps lie in the concentration of light sources (which can be adjusted by changing the light intensity and distance), especially in carrying out This is a very important point when it comes to radiation. Its disadvantage is that the energy consumption is relatively large. A better incandescent lamp product can only be maintained for 3 to 4 hours when the ordinary alkaline battery is used. And the price of incandescent bulbs (especially halogen bulbs) is relatively high, and the cost of repair and replacement is relatively high. Therefore, I think such headlamps are more suitable for 2-3 days of outdoor activities that are easy to recharge batteries, especially for those who must be at night People who engage in outdoor activities. At present, one of the ways to solve the high energy consumption of incandescent lamps is to adopt a combination of LED lamps, and in the case of no need for high beam, use LED lamps to save energy. The advantages of LED lamps are: Low energy consumption, long life. The life of ordinary LED lamps can reach tens of thousands of hours. If properly used, an LED headlight can allow you to enjoy life without repair or replacement. Its disadvantage is that the light is divergent. Not suitable It is used in sports in outdoor environments. However, with the continuous updating of LED technology, this shortcoming will have an essential change in the near future (PETZL's MYO XP has basically solved this shortcoming). Currently, LED lighting is solved. One of the ways to reduce the intensity of lighting is to increase the number of LED heads. However, this method can only solve the headlight's light illumination and cannot fundamentally solve the problem of limited illumination distance. For the outstanding advantages and disadvantages of LED and incandescent lamps, many manufacturers try to balance their characteristics when designing headlamps. Under the premise of retaining advantages, technical means are used to limit the disadvantages of both. To achieve this goal, no Less manufacturers use a combination of two technologies, such as PETZL's DUO and BLACK DIAMOND's GEMINI are typical representatives of such products. Combine the advantages of incandescent lamps and LEDs to meet the demanding requirements of users.
