Led bulb how to light bulb selection evaluation

Guide: The led bulb is familiar to us. After Edison invented the electric light, the light bulb brought light to thousands of households through the transformation of electricity and light. It can be said to be an essential necessities. How about led bulbs, as people's wisdom continues to advance, there have been many changes in the shape and use of light bulbs. For example, led bulbs are the most popular light bulbs on the market. Not only because of its innovation, but more importantly, its quality is standard enough, and it takes a long time to use. So how about led bulbs, let's learn to learn about led bulbs, let everyone know more about led bulbs, learn together!

How about led bulb

How is the led bulb, the service life of the led lamp should be explained in several parts, the life of the led is generally 100,000 hours, and the LED is made to have a certain power. The higher the power, the higher the heat dissipation requirement. . The heat dissipation is not good, and the life of the LED is affected. Then there is the drive power part and so on, which are related to the life of the "LED lamp". How about the led bulb, now our LED lamp life is 30,000 hours, but you have to make it clear that 30,000 hours is not a broken lamp, not bright. We mean that after 30,000 hours, the light decay may be more than 30%. In fact, the current energy-saving lamps are also the standard life, but the people do not know it. How about the LED bulbs, the energy-saving lamps will quickly produce light when they are used for the first time. Decay, generally households reach 20~30% light decay in about 3 months. In the following time, the light decays slowly, and after 3 to 5 thousand hours, it will be greater than 40%, then the lamp will be scrapped.

Led bulb selection evaluation, do you often feel this way, the clothes that are tried on the mall to take home will not have the color at that time? The fresh and bright fruits of the supermarket can not afford the appetite at home? The light in the house is bright, but how to reach out It is difficult to see the five fingers? In fact, this is only a matter of lighting quality. Shopping malls, supermarkets, designer clothing stores, and high-end restaurants all use very high-quality and professional lamps, and even professional to each level, each container, every angle, each piece of clothing has a separate design of different professional lighting. And what these high-value lights do is to make you happy, enjoy shopping, and increase your appetite. After returning home? Under the inferior energy-saving lamps or LED light sources at home, all the colors are almost greatly reduced, the nature becomes oppressive, and even in bright light, often do not see something. The line of sight became uncomfortable, and the night at home was like a smog. The child is not interested in doing homework. The dishes made by his wife have no color. The family only enjoys bright mobile phones and batteries, and then falls asleep.

Led bulb lighting principle

Light-emitting diode bulbs are fundamentally different from traditional incandescent lamps, both in terms of structure and illumination. A diode is a common component in electronic circuits and is made up of a semiconductor PN junction, plus electrode leads and a package. The diode has two electrodes for the PN junction, so it is called a diode. The diode has unidirectional conductivity. There are many types of diodes, such as detector tubes, rectifier tubes, voltage regulator tubes, switch tubes, damper diodes, light-emitting tubes, and photo tubes.

Light-emitting diodes are usually made of semiconductor materials such as gallium arsenide or gallium phosphide. They emit light when they pass a forward current. The color of the light depends on the materials used, and can emit red, yellow, green and infrared light. The light-emitting diodes are generally packaged in a transparent plastic, the length of the pins is positive, and the short legs are negative. Some LEDs have three lead-out pins that emit two colors of light depending on the voltage of the pin.
