LED aluminum flashlight selection and the advantages of what? Now the light-emitting diode as an efficient has been constantly into our lives. With the emergence of a few years ago LED diodes flashlight to the current single-lamp high-power 1W, 3W appears, constantly enrich everyone's flashlight selection. Especially the emergence of aviation aluminum alloy metal flashlight so that many buyers heart. Of course the price has now dropped from the astronomical price. Has been very suitable for many, many buyers. Now the LED flashlight has dropped to a dozen yuan a. High-power single lamp is a new product, the price is relatively high.

 

Here we give you talk about led aluminum flashlight to buy and distinguish:

 

With multiple diodes, the color temperature is high. Giving the visual experience is very bright, this is his characteristics. There is that he is very energy efficient, a five batteries can also serve more than 10 hours. The other is the magnesium alloy metal shell, the appearance of small wind and rain anti-corrosion, it is suitable for outdoor use. But the biggest shortcoming of this product is the irradiation distance is very small, generally about 20 meters. Far away to see the clear. The above is the shortcomings of this flashlight itself. Here are some small factories to see the profits also followed the production, prices continue to decline, resulting in flashlight aluminum alloy material down, and the lack of weight, the other is to meet a lot of people feel bright heart, the current adjustment, so that LED more bright. In fact, LED flashlight diode in the entire cost is not the highest. But the shell magnesium alloy. The most important is the weight and process. Manufacturers are more than the regular production, the component is more foot, the other is very talk about the process. And some small factory process is very rough. And LED is to control the current, or very easy to burn out. So the choice of LED must pay attention to the above points.

The same time as

Another LED multi-lamp and single lamp 1W difference, single light 1W is a new light source, now very popular products abroad. This LED is mainly a light, high power design. There is also a condenser. If the quality is good, can take more than 100 meters away. But the price is higher. Do a good drive circuit. The appearance is also very beautiful. And the metal oxide film is used as an external decoration. Wear durable. The choice of this product must look at the craft and workmanship and the size of the plant. Otherwise the quality can not be guaranteed. But the price is high.

 

LED aluminum alloy flashlight What are the advantages?

 

High energy: energy-saving energy pollution is environmentally friendly. DC drive, ultra-low power (single tube 0.03-0.06 watts) electro-optical power conversion close to 100%, the same lighting than the traditional light source more than 80% energy saving.

 

Long life: LED light source it is called longevity lamp, meaning never turn off the lights. Solid cold light source, epoxy resin package, the lamp body is not loose part, there is no filament light burning, heat deposition, light failure and other shortcomings, the service life of up to 60,000 to 100,000 hours, 10 times longer than the traditional light source life the above.

 

More changes: LED light source can use red, green, basket three primary colors principle, under the control of computer technology to make three colors with 256 gray and arbitrary mixing, can produce 256 × 256 × 256 = 16777216 kinds of colors, the formation of different light The combination of color changes, to achieve a variety of dynamic changes in the effect and a variety of images.

 

Environmental protection: environmental protection is better, the spectrum does not have ultraviolet and infrared, neither heat nor radiation, glare small, and waste can be recycled, no pollution does not contain mercury elements, cold light source, you can safely touch, are typical green Lighting source.

 

High-tech tip: compared with the traditional light monotonous luminous effect, LED light source is low-voltage microelectronics products, the successful integration of computer technology, network communications technology, image processing technology, embedded control technology, it is also digital information products, Semiconductor optoelectronic devices "high-tech tip" technology, with online programming, unlimited upgrades, flexible features.

 

LED aluminum alloy flashlight is a light-emitting diode as a light source of a new lighting tool, it has a power, durable, strong brightness and so on. Buy a good LED light flashlight should pay attention to what:

 

1, the number of moderate. Household generally do not have more than 12, the use of the battery in the 2 to 3 as well, and then a little bit of waves, for other special needs can be determined according to their own needs.

 

2, welding to prison. Each diode is connected by welding on the circuit board, if there is poor contact with the Weld, it may cause the electric beads do not shine or affect the overall use.

 

3, electric beads polished surface as much as possible point. This flashlight is not like ordinary flashlight can adjust the focal length, purchase should be careful not to astigmatism.

 

4, power switch contact to be obvious. This type of flashlight using rotary switch, tighten the open, and then loose on the customs, if the contact is not obvious, it is easy to cause when the phenomenon of off when the light.

 

5, pay attention to waterproof. Because it belongs to the electronic products, flashlight front has a circuit board, once the water prone to short circuit, causing damage.
