LED Flashlight No Pollution Long Life

LED is a new type of flashlight, since the advent of white LED, it has been introduced, but the initial time due to low brightness white LED, high cost, it can be said that such products have been in the "laboratory stage", the price of ordinary people no one Dare to ask, some military products have a small amount of promotion. With the increase in the brightness of white LED, cost reduction, and gradually take the ranks of the public. Brightness improvement is mainly due to the emergence of ITO, brightness almost doubled, and the price, due to the improvement of production technology, but also a lot cheaper.

1. Semiconductor lighting is known as the fourth generation of lighting, can be said to be a replacement product, cost much higher than ordinary light bulbs, but long life Energy-saving aspects of ordinary light bulbs I do not know how much, with LED flashlight 1W-5W range, talk about energy-saving advantages, then put aside the flashlight, LED current market-oriented products in terms of energy consumption between incandescent and fluorescent lamps. But absolutely environmentally friendly, non-polluting. Long life, is the LED's recognized advantages, but the market can be said that the flashlight LED is good and bad, this is too much to say, in this not repeat.

2.LED flashlight Another fatal shortcomings (ordinary people are not easy to find the shortcomings, from a technical point of view, I am here is not good to say), low color rendering index! In the LED display under the color of the incandescent lamp is not true, which from the spectral distribution of the analysis, a technical problem, not repeat them. There is also a drawback, the spot, due to the white LED manufacturing process defects coupled with the reflective cup or lens with the error, likely to cause "yellow circle" problem. Part of the manufacturer does not consider the quality of the device and with the problem, completely copy other manufacturers products, the poor quality of the LED flashlight flooding the market, seriously damaged the reputation of LED, in this deeply indignant, to Jiangsu and Zhejiang, Shenzhen for the most. Fake and shoddy products too much. Taobao dozens of yuan on the LED flashlight its quality can be imagined. Of course, the quality of the flashlight is not.

3. buy flashlight should pay attention to:

1, look at the battery, there are two kinds of ordinary batteries and lithium, although the lithium battery is rechargeable, but low life, about 2 years, LED life of about 10 years, according to the actual situation to choose.

2, to see the bulb, light bulb out of the case, the naked eye is difficult to distinguish it from good or bad, you can see the light in the case of light consistency.

3, look at the aperture, good LED flashlight aperture for a uniform circle, poor LED flashlight spot is divided into yellow and blue uneven distribution.

4, see the brightness, good LED flashlight high brightness, slow decay.

5, to see waterproof, good LED flashlight with waterproof function, good seismic performance, that is resistant to fall.

6, look at the appearance of this more than I will see, I do not say. I chose the aluminum alloy shell, nice.

4. Precautions for use

2, do not overvoltage use, the voltage should not exceed 4.5V, the battery positive forward, do not reverse, otherwise it will burn the circuit board, pay attention to control the torch temperature changes, non-professionals do not open the circuit board.
