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 highly efficient and energy-saving: only a few kWh of electricity is 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, fluorescent lamps, the power saving efficiency can reach more than 90%. At the same brightness, the power consumption is only 1/10 of the ordinary incandescent lamp and 1/2 of the fluorescent tube. If we use LED to replace 50% of our current traditional lighting, the electricity saved in our country every year is equivalent to the sum of the power generation of a Three Gorges Power Station, and its energy saving benefits are very considerable.

2. Ultra-long life of LED lamps: semiconductor chips emit light, no filaments, no glass bulbs, 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 50,000 hours. eight thousand hours).

3. LED lamps are healthier: LED is a green light source. LED lights are 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 color temperature changes; cold light source Low heat 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 well 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. However, 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 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 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, so it can be used in dangerous places such as mines.

8. The market potential of LED lamps is great: 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.
