Weakened blue light high color rendering index LED fluorescent lamps
As a new fourth-generation light source, LED has many unique technical advantages over traditional light sources, such as high luminous efficacy, long life, good directionality, environmental protection, energy saving, and easy control.
The main problem is that the intensity of blue light in the current LED light source is too high, especially 450nm peak blue light, with the characteristics of high relative intensity, the harm of this high intensity blue light on the human retina has become a major constraint on the LED lighting problem, more and more for the world to be concerned about.
The World Health Organization has issued a clear announcement, notifying that ordinary LED lighting sources are hazardous to the human retina; the relevant international LED lighting light biosafety standard IEC/EN62471 has also been published. Authoritative medical institutions data show that the incidence of retinopathy has increased exponentially in recent years, mainly due to the impact of cell phones, iPAD, LCD TVs, LED screens for electronic products, and ordinary LED lamps and lanterns.
Recently on the market hot "full-spectrum" LED lights only to exceed the blue light "hidden" in the red and green light, in fact, the harm of excessive blue light remains.
Explanation on the color rendering index of light-emitting diode light sources
- Light source on the object's color rendering ability is called color rendering, can correctly show the original color of the material need to use the color rendering index (Ra) high light source, the sun's color rendering index is defined as 100, color rendering index (Ra) value closer to 100, the better the color rendering.
- Evaluation of light source color rendering using 15 kinds of sample colors, special color rendering R9 is to evaluate the LED on the vivid color red reproduction quality indicators, Ra, R9 is the same as a higher value is the performance of high-quality LED.
- Compared with ordinary LEDs, full-spectrum LEDs have a more continuous spectrum and a wider color gamut; the color rendering index Ra has been greatly improved and is closer to 100.
- Index (Ra) grade color rendering general application:
- 90-100 1A Excellent Places where accurate color contrast is required
- 80-89 1B / Places that require color to be judged correctly
- 60-79 2 General Sites requiring medium color rendering
- 40-59 3 / Places with low color rendering requirements
- 20-39 4 Poor Sites without color rendering index requirements
- A good LED product manufacturer will weigh the color temperature accuracy, color rendering index, and brightness and other factors to select the right chip.
- Good LED lamps and lanterns, need to have the right color temperature, good anti-glare (weakening blue light) function, general occasions application, color rendering index color rendering 80 or more can be. But for some special applications, such as art classrooms, photo studios, operating rooms, etc., under the premise of meeting other functions, the high color rendering index has special requirements.
Advantages of high color rendering index fluorescent lamps for painting studios with weakened blue light
The company's R & D and production of studio LED fluorescent lamps products, using the industry's top high-brightness lamp beads, lamp bead derating, using long-life high redundancy power supply, combined with highly efficient heat dissipation technology, color rendering index > 97 under the premise of luminous flux up to 118lm / W or more, much higher than the industry's level of 85-90lm / W, to ensure that the continuous service life of 50,000 hours and 10 years of light degradation of less than 5%. The product supports single-ended power supply, the shell is made of modified plastic, giving up the glass shell, lightweight and safe.


The color temperature is above 5300K, the light source is close to the natural light, there is a bright feeling, make people concentrate, suitable for meeting rooms, classrooms, drawing rooms, design rooms, reading rooms in libraries, exhibition windows and other places.
1, high color rendering index: high color reproduction performance.
2. Full Spectrum: The spectrum of light is rich and details are well rendered.
3, weakened blue light: good picture reproduction, to solve the problem of excessive blue light radiation caused by picture distortion.
★ Test report provided by Huamei Testing

The blue light hazard of our LED fluorescent lamps is measured at 5.50 when 100 units of the "no hazard" indicator are allowed!
The testing standard refers to the EU standard, but the color temperature is increased from 4000K to 5600K in the EU standard!
★ Interpretation of selected reports
- It should be noted that: the test report "no harm" column of indicators, belonging to the current LED lighting industry can not achieve a completely ideal state, and had to set up a relatively harmless indicators!
- The corresponding indicators for our LED fluorescent lamps, listed in the red box, show a huge difference from the so-called "no hazard" indicators, reaching the highest photobiological safety level in the industry.
- Under the premise of ensuring that the color rendering index is greater than 96, and 5600k color temperature, in terms of reducing the harm of blue light, the indicators of our products currently reach the world's first level!
- Need to focus on additional information: the test report in the blue light "no harm" column, 100 or less belong to the category of no harm, but this part of the product testing data, the higher, the harm to vision or the existence of cumulative effect.
- Compared with the "speculative" method of reducing blue light radiation in the yellow light band (3500K-4000K), ours is close to the blue light radiation target in the daylight band (5500K-5800K). Under the spectrum condition of 5500K-5800K, we have achieved low power consumption and small blue light radiation control.
