Leading Tech CE Compliant 98Ra Anti Blue Light Eye Protection Special Liquid cooled E27 5W 10W LED bulb for Dormitory Desk Light

Why should we use no blue light led lightign products? 

Let's compare three types of lighting spectrum-traditional fluorescent bulb, common LED bulb and full spectrum led bulb.

1. Fluorescent Spectrum:

Non-negligible lighting risk

1) 380-400nm UV light hurts eyes.

2)High blue light ratio (about 15-20%) is the killer resulting in near sight.

3) High strobe frequency is the chief culprit of eyes' fatigue.
4) High radiation causes damage to brain.
5) Contains heavy metals "mercury", endangering the human body and the environment.

2. Common LED lighting:

Non-negligible lighting risk

1) High blue light results in irreversible hurt to children's eyes.

2) Its incomplete spectrum results in poor light color, which in turn causes children's color weakness.
3) Low color rendering reduces children's color discrimination ability.

3. Our high CRI, no flicker, no blue light (RG0) full spectrum led lighting, the closest to the spectrum of sunlight

The advantage of full spectrum lighting

1) 510nm spectrum: matched with the peak of light absorption of Propioni acnes metabolites, which can cause acne bacteria to die.

2) 592nm spectrum: Matches the peak of light absorption of blood vessels, improving blood circulation
3) 620nm spectrum: Promote osteoblast proliferation and differentiation,
4) 633nm: Effectively enhances skin collagen cell activity
5) 640nm: fasten wound healing
6) 650nm: Matches the peak of light absorption of cell mitochondria and enhances cell function and promotes metabolism.

7) 660nm: Enhance the migration ability of bone marrow mesenchymal stem cells, preventing leukemia,
8) 670nm: Promotes metabolism of the cortex (cell depth repair)
9) 683nm: Matches the peak of light absorption of hair follicle cells, promotes hair regeneration, and maintains a youthful state.
10) 690nm: Promote cell regeneration

Sun color temperature during the day

The closer the spectrum of the lighting fixture is to sunlight, the better the fixture is for eyes.

New Standard for Lamps-Forced measurement of blue light

For the potential hazard of LED blue light, IEC62471 developed by the International Electrotechnical Commission has classified the safety level of blue light hazards of LED light source products. Divided into

1. RG0 (exemption, the lamp does not cause any harm under the limit conditions defined by the standard. The blue light hazard is defined as not causing damage to the retina within 10000s).
2. RG1 (Class I, low risk, no additional requirements, The blue light hazard is defined as not causing damage to the retina within100s.
3. RG2 (Class II, medium risk, the blue hazard is defined as not causing damage to the retina within 25s,
4. RG3 (Class III, High risk, the light source causes harm in a short time.)

Under normal circumstances, it is recommended to use only the products with the blue light hazard classified below RG1, and the color temperature should not exceed 4000K, and the general color rendering index should reach 80 or more.

The Features of Our Eyes Protection LED Lamps

1. The CRI of sunlight is defined as 100. The closer the value to 100, the better the color rendering performance is.

2. 15 kinds of sample colors are used to evaluate the color rendering of the light source, and the special color rendering
property R9 is a quality index for evaluating the vivid color red of the LED.
The higher values of Ra and R9 are the performance of high-quality LEDs. Compared with ordinary LED, the LED eye protection spectrum is more continuous, the color gamut is wider, the color rendering index Ra is greatly improved, closer to 100, and the special color rendering index R9 is as high as 90 or more.

3. LED eye-protection light complements the lack of short-wave violet, cyan, short-wave green, and long-wave red light, which greatly enhances the continuity and integrity of the spectrum. It is a wide color gamut and is closer to the full spectrum of sunlight.
4.In the ordinary LED spectrum, the range of the blue light band is relatively large, and excessive blue light and improper use of the lighting fixture may cause visual damage. Blue light can inhibit melatonin secretion and can cause insomnia. LED eye protection lamp can effectively reduce the blue light hazard of lighting LED light source.
