Basic knowledge of household led lighting lamps and lanterns, rounding

led lighting lamps and lanterns of knowledge & ndash; — Basic knowledge of

LED semiconductor light-emitting devices including semiconductor light-emitting diode ( Hereinafter referred to as LED) Tube, digital tube, symbols, words tube and dot matrix display screen ( Matrix tube for short) And so on. In fact, digital tube, pipe, rice word in sign and the matrix in the tube each light emitting unit is a light-emitting diode.

led lighting lamps and lanterns of knowledge & ndash; — Led light source has the characteristics of the

1, less power consumption, light efficiency is 75 lm/W leds is equal to the brightness of the incandescent lamp power consumption reduced by 80%;

2, long service life: product life for 50000 h, 24 hours of continuous light available 7 years;

3, nanosecond response speed, the dynamic control of brightness and color is more easily, which can realize the dynamic change of color and digital control;

4, the design space is large, and architecture can organic integration, to achieve the effect of didn't see the lights for the light.

5, environmental protection: no harmful metallic mercury, no infrared and ultraviolet radiation.

6, color: different wavelengths produce different colored light, bright saturated, no filter, available red, green, and blue light control after form different color, and can realize full color, gradient and so on all sorts of color effect.

led lighting lamps and lanterns of knowledge & ndash; — Led features:

led lighting is a kind of green light source: low work voltage, less power consumption; Stable performance, long life, Generally for 100000 hours) , short response time, and no pollution to the environment. Although the existing lighting expensive, but still will inevitably take the place of existing lighting devices.

led lighting lamps and lanterns of knowledge & ndash; — Choose led lights important reference

1, spectral components should be no ultraviolet and infrared light. Accept too much ultraviolet light for a long time, not only easy to cause keratitis, will harm the lens, retina, choroid, etc. Infrared easily absorbed by water, excessive infrared light through the human eye lens gathered by a host of absorption, will happen over time the lens degeneration, cataract.

2, light color temperature should be close to natural light. People living in the natural light for a long time, the human eye to light adaptability is strong, good visual effect.

3, no electromagnetic radiation, prevent radiation pollution to protect the brain. It can provide a comfortable space for lighting, and can well meet the demand of people's physical health, the light source is environmental health. Long-term use can protect eyesight and prevent myopia.

4, zero stroboscopic, won't make the eye fatigue phenomenon. Common fluorescent lamp power supply frequency 50 hz, the light at the brightness 100 times per second, belongs to the low frequency and frequency flash, can make the regulation of human organs in the regulation of tension state, result in visual fatigue. If the frequency of the light at the increase to more than hundreds and tens of thousands of hz - - — As a high frequency, the human eye - there will be no stroboscopic feelings; But the real is no stroboscopic dc power supply or solid light-emitting semiconductor devices, Such as the LED light emitting diode) The light is called frequency flash.
