In life, Light is everywhere. Light gives us light all the time. It is not only the light that points the way but also the light that leads to success. The original meaning of light is the Sun, fire, electricity, and other emissions of dazzling people’s eyes, people feel bright, can see objects: such as sunlight, Moonlight, fire. Group of words: Sunlight, light, Moonlight, LightWave, light. The light of life is everywhere, especially at night, walking in the busy streets, street lights, car lights, indicator lights, red street lights are how dazzling, so that we have the power to move forward, so that the city becomes more prosperous, to make the traffic on the road more orderly, so that everyone in accordance with the traffic rules, so that each family in the light, with light, enriched our lives, so that the factory can be orderly production, on-time delivery. To make our home more beautiful and more harmonious. To make our city more colorful. To make our world more beautiful. Isn’t that what you’re doing for me?
With the development of the times, people pursue higher and high to the lamp. Light-emitting diode LED lights are just what people need. As a light-emitting device, LED has attracted much attention because of its advantages over other light-emitting devices.
LED has the following advantages:
(1) long service life: as a solid-state light-emitting device, LED has a longer service life than other light-emitting devices. Its brightness half-life usually reaches 100,000 hours. If the LED is used instead of the traditional automobile lamp, its life will be much longer than the life of the automobile body, with the characteristics of a lifetime without repair and replacement.
(2) low power consumption: LED is a low-voltage device, so in the same brightness, the minimum power consumption, can greatly reduce energy consumption. On the contrary, with the development of technology and materials in the future, it will have higher luminous efficiency. It has been calculated that if all the lighting fixtures in Japan were replaced by LEDs, two large power plants would be reduced, which would be very beneficial to environmental protection.
(3) fast response time: LED can generally respond in tens of milliseconds (NS), so it is a telling device, which is also other light sources out of reach. The high position brake lamp made of LED has greatly improved the safety of the automobile under the high-speed condition
(4) small size, lightweight, and resistance to attack: these are the inherent characteristics of solid semiconductor devices. Color LED can make all kinds of clear and delicate display devices.
(5) easy to adjust light, color, and controllability: as a light-emitting device, LED can be controlled by the current through the change of brightness, but also through the configuration of different wavelength LED to achieve color changes and regulation. Therefore, with an LED light source or display, easy through electronic control to achieve the needs of a variety of applications, and the compatibility of IC computers is extremely difficult. In addition, the application of LED light source in principle is not scenting restrictions, plasticity is very strong, and can be arbitrarily extended to achieve building block assembly. At present, the large color screen display is LED.
There are no environmental pollutants such as mercury and lead in the light source made of LED, which will not pollute the environment. So people call the LED light source “Green” light source is well-deserved
Further, light is hope, a symbol of the future. As long as there is light, one can see where one is going. When people feel lost, light is like a beacon in the dark night, lighting our way forward; when people feel lost, light is like a spring breeze in the white snow, blowing away the ice layer in people’s hearts; When people feel frustrated, the light is like a drop of dew in the vast desert, moistening people’s anxious heart. That’s why light is so important. In life, we must use the light to guide us forward. And if there is no light in life, the world is dark. Like a ship without a rudder, adrift, without a direction, not knowing where to go. Flying around like a chicken with its head cut off. It’s not just a waste of time, it’s a waste of life.
