As a kind of high-efficiency lighting, light-emitting diodes have been constantly entering our lives. With the emergence of LED diode flashlights in the past few years, the emergence of single lamp high-power 1W and 3W has continuously enriched everyone's flashlight choices. In particular, the appearance of metal flashlights made of aviation aluminum alloys makes many buyers excited. Of course the price has dropped from sky-high. It has been very suitable for many, many buyers. LED flashlights have dropped to more than ten yuan a piece. The high-power single lamp is a new product, and the price is relatively high.
The LED flashlight is composed of multiple diodes, and the color temperature is very high. The visual experience is very bright, which is his characteristic. In addition, he is very energy-saving, and a AA battery can last for more than ten hours. The other is the magnesium-aluminum alloy metal shell, which is small in appearance, windproof, rainproof and anti-corrosion, which is very suitable for outdoor use. But the biggest shortcoming of this product is that the irradiation distance is very small, usually only twenty meters. Can't see clearly from a distance. The above are the shortcomings of this torch itself. The following are some small factories that have followed the production because they saw a large profit. The continuous decline in prices has caused the aluminum alloy material of the flashlight to decline, and the weight is insufficient. In addition, to meet the psychology of many people that they think it is bright, the current is increased to make the LED more powerful. Bright. In fact, the diode of LED flashlight is not the highest in the whole cost. It's a magnesium-aluminum alloy casing. The main thing is the weight and craftsmanship. The products produced by big factories are more formal, the weight is more abundant, and the craftsmanship is very particular. And some small factories are very rough. There is also LED is to control the current, otherwise it is easy to burn out. Therefore, the selection 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 type of light source, which is very popular abroad. This LED is mainly a light, high power design. There is also a condenser cover. If the quality is good, it can illuminate more than 100 meters away. But the price is higher. There are drive circuits that do well. The appearance is also very beautiful. And the metal oxide film is used as exterior decoration. Durable wear. The choice of this product must depend on the craftsmanship and workmanship as well as the size of the factory. Otherwise the quality cannot be guaranteed. But the price is high.
Energy-saving energy without pollution is environmental protection. DC drive, ultra-low power consumption (single tube 0.03-0.06 watts) electro-optical power conversion is close to 100%, the same lighting effect saves more than 80% energy than traditional light sources.
Long life: The LED light source is called a longevity lamp, which means a lamp that never goes out. Solid cold light source, epoxy resin encapsulation, no loose parts in the lamp body, there are no shortcomings such as easy burning, thermal deposition, light decay, etc.
