Basic knowledge of LED lights, how much do you know?
Do you know what LED lighting is? Many friends think that this concept is not clear, but it should be exposed to LED lighting. LED lights are filled with all kinds of LED lights in every corner of the city, especially at night, our life can be seen everywhere, let's take a look at the related content of LED lights together!
1. New green environmental protection light source: LED adopts cold light source, low glare, no radiation, and no harmful substances will be produced during use. The same lighting effect LED operating voltage is lower than the traditional energy DC drive (single tube 0.03~0.06W), and the electro-optical power conversion rate close to 100% exceeds 80%. No environmental pollution, no ultraviolet and infrared spectrum, no typical pollution of recycling waste, green lighting, no mercury element, safe touch.
2. Longevity: LED cold light source is not in solid epoxy resin, vibration, light main body and loose parts, no filament burnout, thermal deposition, light attenuation and 60,000 other disadvantages up to 100,000 lifespan is more than 10 times the lifespan of conventional light sources long. The LED performance is stable and can operate normally in the environment of -30 to +50oC.
3. Multiple conversions: LED light source can use the theory of red, green and blue under the control of three-color computer technology with 256 color gray levels, any mixture can produce 256×256×256 (for example, 16777216) colors can be combined to generate . The various colors of the LED combination allow various dynamic changes and various images to be realized.

4. High-tech: Compared with the luminous effect of traditional light sources, LED light sources are low-voltage microelectronic products that successfully combine computer technology, network communication technology, image processing technology and embedded control technology. The size of a chip used in a conventional LED lamp is 0.25mm×0.25nm, and the size of an LED used for lighting is usually 1.0mm×1.0mm or more. LED mold forming table structure, inverted pyramid structure and flip-chip design can improve luminous efficiency and emit more light. Innovations in LED package design include highly conductive metal block boards, flip-chip designs, and bare-board cast leadframes that can be used to design high-power, low-resistance resistors that provide higher illumination than conventional LEDs. This product has higher illuminance. 2. Luminous flux (unit: LM), color rendering index (Ra), color temperature (K), power factor (PF)
5. Luminous flux: mainly refers to the brightness of the product, and the lamps consume electricity to emit light. The higher the speed, the more light energy is emitted. Therefore, it is an indicator of the lighting capability of the light source. When the power consumption of both lamps is the same, the higher the speed, the better the lamp. Typical LED lamps can reach 90-110LM/W time, and even lamps can reach 120-150LM/W. (Traditional incandescent lamps 10-15LM/W energy-saving lamps 30-65LM/W)
6. Two-color rendering index: The color rendering index indicates the ability to reproduce colors. The higher the color rendering index, the more positive the color. Compare the color of the object shape to a reference of the same color temperature or reference light (incandescent or painted). Reducing the percentage of the actual color of the object requires that you use a light source with a high color rendering index to correctly represent the original color of the material, and the color rendering is fine as the value is close to 100. Incandescent lamps 97-100 LED lamps 85-12
7. Color temperature: refers to the color of light, the higher the color temperature, the brighter the color, and the lower the color temperature. Light is red. It is based on sunlight. There are three types of normal color temperature. Warm light (yellow light) 2700-3500K represents the symbol: RN. Neutral white 4300-5000K means: RZ white light (cool white) 5800-6500K. Expression: RR.
8. Power factor: The power compensation of the power conversion source. The size of the power factor depends on the power factor of the driving power supply. The larger the power factor, the higher the conversion efficiency.
9. Heat dissipation capacity: The heat dissipation capacity of LED products directly affects the product life and light attenuation rate. Products with higher power and longer lighting time require higher heat dissipation. Traditional LED products use metal housings with internal or external heat sinks to dissipate heat from the fixture.
The energy-saving effect of 10LED lighting is 7-10 times that of traditional incandescent lamps, and the energy-saving effect is very good.
