LED indoor lighting improves the atmosphere and warmth of the home.Nowadays, many indoor lighting fixtures are not only lighting,

Still have the function of adornment beautiful.With the increasing maturity of LED technology, LED research and development has 

also become the mainstream direction of bedroom lighting design.

Now let's learn about LED lighting.

1. Materials for LED indoor lighting

Production materials are more common: metal, plastic, glass, etc., metal service life is long, not aging, but very easy to go out of 

date.The metal parts slowly oxidize,Use time is about 5 years.Plastic lamps and lanterns have short life, fast aging speed and easy 

to be deformed by heat.

2. Features of LED light source

1. Low power consumption: Leds with a luminous effect of 75Lm/W consume 80% less power than incandescent lamps with the 

same brightness.

2. Long life: the product life is as long as 50000h, and it can be lit continuously for 7 years.

3. Nanosecond response speed: it makes the dynamic control of brightness and color easier, and enables the dynamic change 

of color and digital control.

4. Large design space: it can be perfectly integrated with the architecture to achieve the effect of not seeing the light but the light.

5. Environmental protection: no harmful metal mercury, no infrared and ultraviolet radiation.

6. Color: Different wavelengths produce different color light, which is bright and saturated. No filter is needed.And can achieve full 

color, gradient and other color effects.

3. Selection of LED lamps

1. There should be no ULTRAVIOLET or infrared light in the spectral components.Long-term too much accept ultraviolet ray, 

cause keratitis easily not only, still can pair of lens, retina, choroid Cause harm.Infrared ray is easily absorbed by water. When 

too much infrared ray passes through the lens of the eye, it is absorbed in large quantities. As time passes, the lens will denatured.

It causes cataracts.

2, the color temperature of light should be close to natural light.People live under natural light for a long time. Human eyes 

have strong adaptability to natural light and good visual effect.

3. No electromagnetic radiation.It can provide comfortable illuminant space already, the physiology health demand that can 

satisfy a person very well again, it is the healthy illuminant of environmental protection.Use for a long time Can protect eyesight, 

prevent myopia.

4, zero stroboscopic, will not make the eye fatigue phenomenon.The power supply frequency of ordinary fluorescent lamp 

is 50 Hertz, which means that the luminous time is 100 times per second bright and dark, which belongs to low frequency

Frequency flash, will make the human eye regulatory organs in a tense regulatory state, resulting in visual fatigue.If the 

luminous frequency increases to hundreds or tens of thousands of Hertz --Become high frequency, the human eye will not have 

the stroboscopic feeling;But true stroboscopic light is emitted by dc powered or semiconductor solid state light-emitting devices 

(such as LED light-emitting diodes)Light is called a frequency - free flash.

The above introduced LED lighting knowledge, I hope to give you some help.
