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

very high, and the equivalent illuminance exceeds 1500 lux. To put it simply, it is required to view blue light with a wavelength below 445nm as harmful blue light, and blue light with a wavelength above 445nm to be beneficial blue light. The requirement for anti-blue light product is to shield as much harmful blue light below 445nm as possible and keep as much beneficial blue light above 445nm as possible. Why keep Blu-ray above 445nm? Because blue light above 445nm has a great impact on the rhythm of our human body, and its existence improves our work efficiency during the day. Excellent anti-blue light products mainly shield harmful blue light below 445nm, properly shield blue light of 450-480nm, and let other visible light pass through as much as possible. Many unqualified anti-blue light products block a large amount of other visible light, causing color distortion and affecting visual performance. The anti-blue light products on the market mainly block blue light (ultraviolet rays) below 420nm, which hardly helps in shielding blue light. It is recommended to choose a light source with a color temperature of 4000-6000K during the day, and a warm white color of 4000K or close to 4000K at night. If the color temperature cannot be adjusted, it is recommended to choose a product with a color temperature of 4000K first, which can meet the needs of both day and night. The excellent LED spectral color temperature is 4000K, and the blue light component is obviously less.

The following is different functions of different wavelengths.

1.510nm spectrum: matched with the peak of light absorption of Propioni acnes metabolites, which can cause acne bacteria to die.

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.

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.
