On May 21st, 2015, Jingke Electronics President and Assistant Song Dong received an interview with Li Hui, the host of Phoenix Satellite TV Studio, and published the theme of "The Story of Relativity and Flash".
The host Li Hui mentioned that when talking about the flash, people's initial impression was that of the "state", and then they took some precious black and white images. But in fact, the application of flash in today's life is in the field of smart applications, such as the application of mobile phones to take pictures of food and our dear family. So what will happen to the origin, development and future application of the flash, it may be able to transmit some of our information as a wireless signal in the future. Song Dong said that the first photography was the application of magnesium powder for illumination. The use of life in photography was a true portrayal of the photographer at the time, and the appearance of the flash was to liberate humans from magnesium powder.
In the eighteenth century, the flashlight was made of magnesium powder. People often saw Huang Feihong and Empress Dowager Cixi taking photos with magnesium powder in the movie. At that time, magnesium powder was considered to be a safe flash material. It was zero-pollution, safe, and easy to carry, but magnesium powder could not meet the needs of continuous shooting. After more than a hundred years of development, by the 19th century, a small, explosion-free xenon flash lamp appeared, which can be continuously shot. But it needs to be charged every 3-4 seconds to meet the fast shooting needs of the lens. In 2001, there was a more compact camera flash in Japan. It was also a Xenon flash, and the phone also had a shooting function at the time. Its appearance made people improve their shooting needs and shooting. More demanding. At this point, the LED slowly entered the application of the mobile phone flash.
The host suggested that the advantages of professional cameras and mobile phone flashes? Song Dong said that LED flash also has advantages and disadvantages. Its advantage is that it is small in size and can be applied to mobile phones, while SLR cameras are bulky. The disadvantage of the flash of the mobile phone is that the area of ​​the radiation is small, and the angle that can be photographed is smaller than that of the SLR camera. For example, a single camera can shoot more than 3 meters, and a mobile phone flash is usually an object within 3 meters. This is also the case that mobile phone manufacturers are considering taking pictures of consumers with their mobile phones, mainly shooting close-up objects such as selfies, food, pets and children. It achieves small size, requires low power, and can be continuously shot. Although the previous LED flash is much lower in brightness than the xenon lamp, with the development of LED in recent years, the luminous flux of the LED flash has been increased from 150lm to 500lm.
In this regard, the host proposed the biggest change in the smart phone after the development of the LED flash? Song Dong proposed that the LED has a two-color temperature flash, which can ensure that the picture is clear whether it is sunny or rainy. The previous xenon lamp could not be connected with the intelligent software, but the LED flash can be used, and the three-color temperature scheme is also a popular one. In the future, it will also develop in the direction of optical communication. The flash will be connected to Light Fi for wireless data transmission, which brings convenience to our lives. Perhaps, it will one day be able to measure your body's various indicators, and then use your mobile phone to analyze your physical condition, which is also a development in medical lighting.
Song Dong believes that LED is a luminous device. To make good use of this light, you need to match it well. Using a flash with LEDs, Jinko can provide a complete solution that enables efficient use of the entire light while miniaturizing the device. He said that after decades of development, LED development has always been inseparable from display technology. LEDs were originally used in backlights for mobile phones, including button displays. Through years of technical research and development and production, Jingke Electronics has been able to mass produce LED flash products. (This article is the electronic submission of Jingke)
