First, let’s understand the concept of spectrum:
The spectrum is a band of LED lights kenya that is divided into a series of monochromatic light after being split by a dispersion system (such as a prism and a grating), and then arranged in order according to the wavelength.
And the sunlight spectrum
Before the emergence of artificial light sources, sunlight not only provided illumination and energy to the earth, but also regulated human physiological rhythms and had a profound impact on human psychology and physiology.
Sunlight is the most natural and healthy natural light that we are most familiar with. Below are various spectral comparison charts.
The full spectrum imitates the sunlight spectrum, with low blue light and high color rendering, and is more eye-friendly than ordinary LED lights kenya:
The main differences are as follows:
1.Low blue light
Everyone knows that electronic products can cause blue light hazards. In fact, lamps and lanterns also cause blue light hazards.
1) It will cause visual fatigue and affect learning and work efficiency;
2) Damage eye tissue, easily leading to macular degeneration and cataracts;
3) Affects melatonin secretion, leading to decreased sleep quality and even insomnia;
The short-wavelength blue light part of the full spectrum is relatively low. One thing must be mentioned here: the lower the color temperature, the lower the blue light value. Therefore, most home environments use 3000k-4000k. You can choose 3000k or 3500k in the bedroom to reduce blue light intake before going to bed.
2) Good color rendering
If the color rendering index is too low, it will affect the human eye’s judgment of the color of the object. Full-spectrum lamps have a relatively high color rendering index and can better restore true colors.
3) Impact on human body’s work and rest
According to the body’s biological clock, the human brain usually starts secreting melatonin at 9 or 10 pm.
Blue light can inhibit melatonin produced by the pineal gland of the human brain. Long-term exposure to high blue light can even cause sleep disorders. Full spectrum can reduce this situation.
Here are some full-spectrum lamps recommended to you, all from our brand [Lujia Liangpin]. Full-spectrum ceiling lamps of different styles and sizes can meet the needs of living rooms and bedrooms:
1) Full Spectrum Cookie Ceiling Light
Cute shape, comfortable lighting, the first choice for bedroom lighting; looking up is like seeing a cookie, paired with comfortable and eye-protecting lighting, it is really healing.
2) Full Spectrum Cheese Cube Ceiling Light
The design is inspired by cheese, and the creamy and cute shape is suitable for bedroom installation. Bedrooms have relatively high requirements for light.
The full spectrum supports stepless dimming. It also has a night light mode at night, which is also convenient for getting up at night and watching movies on the bedroom projector.
It’s one that everyone, big and small, will love.
3) Pebble living room ceiling light
Simple shape, sufficient brightness, suitable for living room installation; and equipped with stepless dimming and intelligent control, it is more convenient.
If your home has large white walls, or light-colored or apricot-colored wall paint and space background color, this style of living room ceiling lamp is also more suitable.
As people’s demand for light increases, it is believed that full-spectrum lamps will become more and more popular in the future, helping to protect the health of home lighting.
The way LED lights kenya emit light is usually:
Blue light chip + phosphor
Purple chip + phosphor
No matter which light-emitting method is used, it can emit a “full spectrum” in a “relative sense”. The so-called full spectrum is based on sunlight, and other artificial light sources should be as close as possible to sunlight.
Those who choose to buy full-spectrum lamps are simply for the purpose of high CRI, low blue light or photobiological effects.
But the reality may still be far from your ideal.
Visible light and invisible light:
The sun has seven colors of visible light: red, orange, yellow, green, cyan, indigo, and violet. When concentrated, it becomes white light. Invisible light, located outside the red light area is called infrared light, with a wavelength greater than 760nm, up to 5300nm; located outside the purple light area is called ultraviolet light, with a wavelength of 290~400nm.
If: Ultraviolet rays certainly have many benefits, but what are the consequences of excessive ultraviolet rays?
Ask your mother. The so-called full-spectrum LED lights must simulate the effect of sunlight and contain at least ultraviolet and infrared components. Then the dosage control is Called the number one task.
The picture below is the sunlight spectrum measured around 6 pm. Additional information: the color tolerance is 0.63SDCM, the CRI Ra is 98.9, and the R9 is 99
Note: Affected by the environment, the measurement data will have slight errors.
Blu-ray:
The peak of blue light has a great relationship with the color temperature. Even if it is sunlight, there is a huge difference between the blue light data measured at noon and the morning and evening measurements.
When we buy LED lamps, we don’t look at blue light in general, but mainly look at the peak height of short-wave blue light (wavelength below 455nm).
The picture below is an LED bulb that has been exposed to a certain positive white light. Please note that the color rendering index is Ra84.5 and R9 is 12.
Therefore, whether it is full-spectrum LED, sunlight or ordinary LED lamps, the color temperature of the light source determines the peak of blue light to a large extent.
To sum up:
In theory, full-spectrum LED lights kenya will be more prominent in color rendering index.
But if you want to pay attention to photobiology, you must consider the dose of invisible light, otherwise the gain outweighs the loss.
For home use, try to choose lamps with low color temperature and RG0 certification, with the highest color temperature not exceeding RG1.
Full-spectrum LED lamps are probably still in the gimmick stage (no solid evidence, just speculation). But neither does the price
