The LED light is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connects the chip and the circuit board with silver or gold wires, and is sealed with epoxy resin around it to protect the inner core wire. Finally, the housing is installed, so the shock resistance of the LED light is good. So what are the advantages of LED lights?
1. LED lamps are efficient and energy-saving: only a few kilowatt-hours of electricity are consumed for 1,000 hours (ordinary 60W incandescent lamps consume 1 kWh of electricity for 17 hours, and ordinary 10W energy-saving lamps consume 1 kWh of electricity for 100 hours). Research data shows that because LED is a cold light source, Semiconductor lighting itself does not have any pollution to the environment, compared with incandescent lighting lamps, and fluorescent lamps, the power saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 of the ordinary incandescent lamp and 1/2 of the fluorescent tube.

2. Ultra-long life of LED lamps: semiconductor chips emit light, no filaments, no glass bulbs, are not afraid of vibration, not easy to break, and the service life can reach 50,000 hours (the service life of ordinary incandescent lamps is only 1,000 hours, and the service life of ordinary energy-saving lamps is only 1,000 hours. eight thousand hours).

3. LED lamps are healthier: LED is a green light source. The LED lamp is driven by DC, no stroboscopic; no infrared and ultraviolet components, no radiation pollution, high color rendering, and strong luminous directionality; good dimming performance, no visual error when the color temperature changes; cold light source The heat is low and safe to touch; these are out of reach of incandescent and fluorescent lamps. It can not only provide a comfortable lighting space but also will meet the needs of people's physical health. It is a healthy light source that protects eyesight and is environmentally friendly.

Due to the low power and low brightness of a single LED at present, it is not suitable to be used alone, but assembling multiple LEDs together to design a practical LED lighting fixture has broad application prospects. The lighting designer can determine the shape of the optical system, the number of LEDs, and the power of the lighting according to the requirements of the lighting object and the luminous flux; it is also possible to combine several LED light-emitting tubes into a "secondary light source" of a point light source, a ring light source or a surface light source. Light source", design lamps and lanterns according to the combined "secondary light source".

4. LED lamps are green and environmentally friendly: they do not contain harmful elements such as mercury and xenon, which is conducive to recycling and does not produce electromagnetic interference (ordinary lamps contain elements such as mercury and lead, and electronic ballasts in energy-saving lamps will generate electromagnetic interference. ).

5. LED lamps to protect the eyesight more: DC drive, no stroboscopic (ordinary lamps are AC driven and will inevitably produce stroboscopic).

6. LED lamps have high light efficiency: low heat generation, 90% of the electric energy is converted into visible light (80% of the electric energy of ordinary incandescent lamps is converted into heat energy, and only 20% of the electric energy is converted into light energy).

7. The safety factor of LED lamps is high: the required voltage and current are small, the heat generation is small, and there is no potential safety hazard, which is suitable for dangerous places such as mines.

8. LED lamps have great market potential: low-voltage, DC power supply, battery, solar power supply, which is conducive to providing lighting for remote mountainous areas and outdoor lighting, and other places that lack electricity and electricity.

9. LED lamps are more artistic: light color is the basic element of visual aesthetics and an important means to beautify a room. The selection of the light source directly affects the artistic effect of the light. LED shows unparalleled advantages in the art of light color display lamps; the current color LED products have covered the entire visible spectrum range, and have good monochromaticity, high color purity, red and green. The combination of, yellow LED makes the choice of color and grayscale (16.7 million colors) more flexible. Lamps are luminous sculptures, and the material form of lamps constructed by materials, structures, shapes, and textures is also an important means of displaying art. LED technology makes room lamps combine science and artistry better, breaking the borders of traditional lamps and lanterns, beyond the inherent concept of so-called lamps and lanterns, lamps and lanterns are designed in the artistic creative expression of visual perception and form, with an A whole new perspective to recognize, understand and express the subject of light. We can make more flexible use of the combination of light and dark, the combination of light and color, the advantages of material and structural design in optical technology, improve the degree of freedom of design to weaken the lighting function of lamps, make lamps and lanterns become a kind of visual art, create comfortable and beautiful light art effects. For example, LED lamps made of translucent synthetic materials and aluminum similar to candles can be placed on the ground, corners, or tables at will. The concept is simple and relaxed. The visual experience and light experience conveyed by the form make the lamps full of fun and vitality. the living body.

10. LED lamps are more humane: Undoubtedly, the relationship between light and people is an eternal topic, "people see the light, I see the light", is this classic phrase that has changed countless designers' perception of lights. know. The highest state of lamps and lanterns is the "shadowless lamp", which is also the highest embodiment of humanized lighting. There are no traces of common lamps in the room so that people can feel the light but cannot find the light source, reflecting the humanized design that perfectly combines light and human life.

In summary, LED lamps are now the mainstream of the market, and they are more valuable and advantageous in terms of economics, practicality, and sustainable development.
