In recent years, led bulbs have been widely used in our daily lives. They are not only environmentally friendly, but also have no pollution to the environment and have a very long service life. On a global scale, whether it is urban lighting or home lighting is a better choice. The following editor of LED lamp bead manufacturers will introduce to you what are LED bulbs and the advantages of LED bulbs.

A led bulb is a kind of lamp that uses light-emitting diodes as the main material to make outdoor lamps. It can emit light mainly because we can make the PN junction of this semiconductor achieve the light-emitting effect by using weak electric energy, which means that we In the case of a certain forward bias voltage and current, the electrons injected into the P and N regions undergo radiative recombination when they diffuse to emit a light source. Compared with traditional light bulbs, led lights have the advantages of high luminous purity, low power consumption, and long life.

    advantage:

    1. Energy saving. The energy consumption of white LEDs is only 1/10 of that of incandescent lamps and 1/4 of that of energy-saving lamps;

    2. Longevity. The life span can reach more than 100,000 hours, which can be described as "one-time-for-all" for ordinary household lighting;

    3. It can work at high speed. Energy-saving lamps will turn black and quickly break if they are frequently started or turned off;

    4. Solid-state packaging, which belongs to the type of cold light source. Therefore, it is very convenient to transport and install, and can be installed in any miniature and enclosed equipment. It is not afraid of vibration and basically does not need to consider heat dissipation;

    5. LED technology is advancing with each passing day, its luminous efficiency is making amazing breakthroughs, and the price is constantly decreasing.

The LED bulbs of LED lamp bead manufacturers are a kind of green light source. The led bulb is driven by DC, no stroboscopic; no infrared and ultraviolet components, no radiation pollution, high color rendering and strong light-emitting direction; good dimming performance, no visual error when the color temperature changes; cold light source The heat is low and it is safe to touch; these are beyond the reach of incandescent and fluorescent lamps. It can not only provide a comfortable light space, but also meet people's physiological health needs. It is a healthy light source that protects eyesight and is environmentally friendly. Because a single LED has low power and low brightness, it is not suitable to be used alone. However, assembling multiple LED bulbs together to design a practical LED lighting fixture has broad application prospects. The luminaire designer can determine the shape of the luminaire’s optical system, the number of LED bulbs and the size of the power according to the needs of the lighting object and luminous flux; it is also possible to combine several LED light-emitting tubes to design a point light source, a ring light source or a surface light source. "Secondary light source", LED lamp bead manufacturers design lamps according to the combined "secondary light source".

Light color is the basic element of visual aesthetics and an important means to beautify the room. The selection of the light source directly affects the artistic effect of the light. LED bulbs show unparalleled advantages in the art of light color display lamps; colored LED bulb products have covered the entire visible spectrum, and have good monochromaticity, high color purity, red, The combination of green and yellow led bulbs allows greater flexibility in the choice of color and grayscale (16.7 million colors). Lamps are luminous sculptures. The material form of lamps constructed from materials, structure, form and texture is also an important means of displaying art.

The led bulb technology enables the room lamps to better organically combine science and artistry, breaking the borders of traditional lamps, and surpassing the inherent concept of so-called lamp shape. Lamp design is based on the artistic creativity of visual perception and shape. A new perspective to recognize, understand and express the theme of light. The advantages of light and dark matching, light and color combination, material and structural design in optical technology can be used more flexibly, and the design freedom can be improved to weaken the lighting function of the lamp.
