What Is an Ultraviolet Flashlight?

High-power flashlight, also known as LED high-power flashlight, is a new type of lighting tool that uses light-emitting diodes as a light source. It has the advantages of power saving, durability, and high brightness. Now light-emitting diodes as a light source have been constantly entering our life.

(I) LED light emitting principle

This is the parameter of the CREE LED, beyond this is generally a virtual standard.

Q5 350mA brightness 107-114 Lumens, maximum current 1000mA (up to 220-250Lumens)

Q4 350mA brightness 100.4-107 Lumens, maximum current 1000mA

Q3 350mA brightness 93.9-100.4 Lumens, 700mA brightness 152.1-162.6 Lumens

Q2 350mA brightness 87.4-93.9 Lumens, 700mA brightness 141.6-152.1 Lumens

P4 350mA brightness 80.6-87.4 Lumens, 700mA brightness 130.6-141.6 Lumens

P3 350mA brightness 73.9-80.6 Lumens, 700mA brightness 119.7-130.6 Lumens

Different from ordinary flashlights LED flashlights are composed of multiple diodes and have a high color temperature. The visual feeling is very bright, which is his characteristic. What's more, he is very energy-efficient and can run for more than ten hours on a single AA battery. The other is a magnesium-aluminum alloy metal casing, which is compact in appearance, windproof, rainproof and corrosion-resistant, and is very suitable for outdoor use. But the biggest disadvantage of this product is that the irradiation distance is very small, usually about 20 meters. You can't see far away. The above are the shortcomings of this flashlight itself. The following are some small factories that see the large profits also follow the production, the price continues to fall, causing the aluminum alloy material of the flashlight to fall, and the amount is insufficient, and the other is to cater to the hearts of many people who feel bright, adjust the current to make the LED more bright. In fact, the LED flashlight's diode is not the highest in the entire cost. Instead, it is a magnesium-aluminum alloy shell. The most important are weight and craftsmanship. The production of big factories is relatively regular, the quantity is relatively sufficient, and the technology is very simple. And some small factories have rough craftsmanship. There are also LEDs that need to control the current, otherwise they will burn out. So the choice of LED must pay attention to the above points.

In addition, the difference between LED multi-lamp and single-lamp 1W, single-lamp 1W is a new light source, which is very popular in foreign countries. This LED is mainly a light, high power design. There is also a condenser. If the quality is good, it can reach more than 100 meters. But the price is higher. All that is done is a driver circuit. The appearance is also exquisite. And the metal oxide film is used as the exterior decoration. Durable. The choice of this product must depend on the process and workmanship as well as the size of the plant. Otherwise quality cannot be guaranteed. But the price is high.

advantage

High energy saving: energy-saving energy is environmentally friendly without pollution. DC drive, ultra-low power consumption (single tube 0.03-0.06 watts), electro-optical power conversion is close to 100%, and the same lighting effect saves more than 80% of energy than traditional light sources.

Long lifespan: LED light sources are called long-life lamps, which means lights that never go out. Solid cold light source, epoxy resin package, there is no loose part in the lamp body, there are no shortcomings such as easy to burn filament, thermal deposition, light decay, etc. The service life can reach 60,000 to 100,000 hours, which is 10 times longer than the traditional light source the above.

Multiple changes: LED light sources can use the three primary color principles of red, green, and basket. Under the control of computer technology, the three colors have 256 gray levels and can be arbitrarily mixed to produce 256 × 256 × 256 = 16777216 colors, forming different lights. The combination of colors can be changed in various ways to achieve a variety of dynamic changes and various images.

Environmental protection: better environmental protection benefits, no ultraviolet and infrared in the spectrum, no heat or radiation, little glare, and waste can be recycled, no pollution, no mercury element, cold light source, can be safely touched, belongs to the typical green Lighting source.

Gaoxinjian: Compared with the monotonous luminous effect of traditional light sources, LED light sources are low-voltage microelectronic products, which successfully integrate computer technology, network communication technology, image processing technology, embedded control technology, etc., so they are also digital information products. The "high-tech" technology of semiconductor optoelectronic devices has the features of online programming, unlimited upgrades, and flexibility.

LED strong light flashlight is a new type of lighting tool which uses light emitting diode as light source.

1. Environmentally friendly lamps and protect the earth-traditional fluorescent lamps contain a large amount of mercury vapor. If the mercury vapor is broken, it will volatilize into the atmosphere. However, led bright light flashlights do not use mercury at all, and LED products do not contain lead, which protects the environment. Led glare flashlights are recognized as green lighting for the 21st century.

2. Efficient conversion and reduction of heat generation-traditional lamps will generate a lot of thermal energy, while LED lamps convert all electrical energy into light energy, which will not cause energy waste. Moreover, the documents and clothing will not fade.

3, quiet and comfortable, no noise-led bright light flashlight will not produce noise, it is a good choice for occasions using precision electronic equipment. Suitable for library, office and other occasions.

4. The light is soft and protects the eyes-the traditional fluorescent lamp uses AC power, so it will produce 100-120 strobes per second. The led strong light flashlight directly converts AC power to DC power without flicker and protects the eyes.

5, no UV, no mosquitoes-led strong light flashlight does not generate ultraviolet rays, so there will not be many mosquitoes around the light source like traditional lamps. The room will become cleaner and more tidy.

6, adjustable voltage 80V-245V-traditional fluorescent lamps are lit by the high voltage released by the rectifier, when the voltage is reduced, it can not be lit. The led strong light flashlight can be illuminated within a certain range of voltage, and the brightness can be adjusted.

7, energy saving, longer life-led strong light flashlight consumes less than one-third of the traditional fluorescent lamp, life is 1000 times the traditional fluorescent lamp, can be used for a long time without replacement, reducing labor costs. More suitable for occasions that are difficult to replace.

8, sturdy and reliable, long-term use-Lled flashlight body itself uses epoxy instead of traditional glass, more sturdy and reliable, even if hit on the floor LED will not be easily damaged, can be used safely.

Glare flashlight design

Some bright flashlights are designed to be placed on guns to aim at targets.

Multifunctional flashlight

This multi-functional bright flashlight has a high-voltage self-defense function, which works in synchronization with the alarm sound. If a gangster wants to use the high-voltage function in a multi-function flashlight to commit a crime, it will emit a loud alarm sound, which will undoubtedly set fire to the gangster. In this way, the gangster's attempt to purchase a multi-function flashlight will be restricted.

Rechargeable battery flashlight

From the perspective of the popular flashlight classification in the market, there are mainly two types: rechargeable battery flashlights and non-rechargeable battery flashlights. Rechargeable flashlights are classified into lead-acid batteries, lithium batteries, and NI-H batteries by battery classification. Etc. Because lead-acid batteries are currently cheap, their market share is relatively large.
