Tianjin Koretoyo factory outlets today recommended explosion-proof flashlight light-emitting diode emitting principle is Ⅲ-Ⅳ compound explosion-proof flashlight models, such as GaAs (gallium arsenide), GaP (Gallium Phosphide), GaAsP (gallium arsenide phosphorus) and other semiconductor made of Its core is a PN junction. IN feature so that it has a general PN junction that is forward, reverse blocking, breakdown characteristics. In addition, under certain conditions, where there is explosion-proof flashlight, it has luminescent properties. In the forward voltage, electrons from the N zone injection P area, hole injection from the P District N District. Into other areas of minority carriers (minority) part of the majority carriers (many children) composite and light, as shown in FIG. Tianjin factory outlets today recommended Koretoyo 2 explosion-proof flashlight, middle distance (2 meters to 50 meters) high power LED products, especially products for good 3W, 3W chip is also recognized as the most mature lumen of the company's products, to buy a 80 lumens about brightness, low battery consumption, especially for night travel. If you use a good product, concentrating well, it can shine very far. The use of time you can use a simple calculation in junior high school to master knowledge of electronics, such as using a 3.6V 2000ma battery-driven operating current of about 1A is approximately 3W of power to run explosion-proof flashlight, so you can have two hours of use , in fact, decreased with the voltage and current will be significantly decreased, while the decrease in brightness are not so obvious, this is a great advantage of LED, unless the driver circuit remains at full power, or the actual use of time much longer than the calculated value to the top The 1000ma battery, for example, the actual time may be more than four hours. How much proof flashlight | Professional well-known manufacturers Koretoyo explosion | explosion-proof flashlight from Zhejiang Xingtai Koretoyo provide explosion-proof electrical Ltd. Tianjin Office. Zhejiang Koretoyo explosion-proof electrical Ltd. Tianjin Office (www.tjfangbao.com) is Tianjin, explosion-proof lighting leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . Explosion in Koretoyo leadership with the staff warmly welcome all inquiries negotiations to create Koretoyo better future proof.
