However, its luminescent properties was not steady and the light “flash” so we call it “flashlight”. In late 1960s,flashlight was endowed with the lighting function as the alkaline battery emerged.
A brief about flashlight development
1.The original flashlight comes into use after being running-in for a time. In the beginning we used the old fashion flashlight with some defect features which was regarded as the first generation flashlight. Using the osram lamp and alkaline batteries will be considered as its main characteristic,with plated iron appearance as external housing.
2.The following development of flashlight are incandescent flashlight and xenon lamp that are a little advanced than the older one. However, there was still weakness in design and brightness. The light bulb with injected protective gas and using the high-performance battery were considered as the second generation flashlight.
3.In 1980s,the high power flashlight has appeared with much more favorable advantages in design and usage. The third generation of flashlight applies the latest technology - LED. As the LED applying in flashlight, its color temperature is improved than ever have. The LED color temperature is very close to white light with low power dissipation. The third generation of flashlight is characterized by LED. Due to the good structure of led, LED own superb reliability. The lighting mode appeared on the flashlight has been gained a huge popularity in its debut.
4.By now, The usage, quality, performance ,brightness and design of the forth generation flashlight are moving to mature stage . The fourth generation flashlight was installed a new programmed intelligence chip via a professional software customized lighting modes. We call it intelligent flashlight which is a brand new generation high power led flashlight.
Above all is the history of flashlight development from the first generation old fashion flashlight to the fourth generation. Many flashlight features are improved. Hence, we can draw a conclusion that every product will become mature as the time goes by.
