Have you ever noticed that people have different feelings under different colors of lighting? For example, under warm colors such as yellow lighting, people will feel relaxed, lazy and leisurely, and under cool colors such as white lighting scenes Under the lighting, you will feel calm and serious. Under the lighting of different colors, people's psychological feelings are completely different.

What's going on? In fact, this is because the "color temperature" of the light comes into play. Light also has colors, and under different colors of light, people's visual and psychological feelings are different. Therefore, many lighting scenes have specific color temperatures. Requirements, especially for classroom lighting, have national standards as mandatory requirements. Since color temperature is so important, we will talk about it in detail today!

01. What is color temperature

Color temperature was proposed by the British physicist Lord Kelvin at the end of the 19th century. Therefore, the measurement unit of color temperature is "K" ( Kelvin ).

color temperature is the color of light, which is what we often call cold light and warm light. Under common light sources, the lower the color temperature, the warmer the hue, and the higher the color temperature, the cooler the hue.

The color temperature of sunlight also changes gradually throughout the day. Its color temperature will change with the passage of time during the day. The color temperature is lower at sunrise and sunset, showing a warm yellow color, while at noon the color temperature is higher and the light color is bluish. .

02. The influence of color temperature

The color temperature of lighting can affect the human body's circadian rhythm, body temperature, and alertness, and indirectly affect work efficiency, physiological health, and psychological emotions.

Impact on emotions:

Different color temperatures will also bring different feelings to the human body, causing people to have different psychological feelings and emotional experiences. Cold light can make people concentrate better, and warm light can make people feel warm and relaxed. . Therefore, different environments require lighting products with different color temperatures.

Effect on sleep:

Low color temperature light source will promote the secretion of melatonin. Warm yellow light makes people relaxed and more likely to cause drowsiness. High color temperature will make people focused and excited, making them less likely to feel drowsy.

Impact on learning and work:

High color temperature light sources can increase people's brain excitement, focus their attention, and improve their brain activity. Light sources with low color temperatures can make people feel relaxed and reduce concentration and concentration.

03, classroom lighting requirements for light color temperature

Since color temperature has a vital impact on the human body, especially classroom lighting is related to the vision protection and learning efficiency of children and adolescents, the national standard stipulates the color temperature of classroom lighting.

· GB7793-2010 "Hygienic Standards for Lighting and Lighting in Primary and Secondary School Classrooms" stipulates that classrooms should use light sources with a color temperature of 3300K-5500K.

· GB 40070-2021 "Hygienic Requirements for Myopia Prevention and Control of School Supplies for Children and Adolescents" was officially released in February 2021 and officially implemented on March 1, 2022. It stipulates: The relative color temperature of ordinary classroom lighting fixtures should be no less than 3300 K , and not greater than 5300 K.

04, Hongmai Optoelectronics, focusing on classroom lighting solutions

One of the main problems in current classroom lighting is that the color temperature is too high. Although it can allow students to concentrate on learning, it is easy to if they are in a state of excitement and high concentration for a long time. Brain fatigue and visual fatigue. If this continues, not only will it run counter to the original intention of improving learning efficiency, but students' visual health will also be threatened.

"Hongmai Optoelectronic Educational Lighting" adopts 5000k standard color temperature, taking into account the comfort, authenticity, safety and health of the light source, and comfortably illuminates every corner of the classroom. Every specification parameter of the lighting products produced and developed by

Hongmai Optoelectronics strictly complies with and is better than the national standards: sufficient illumination, no glare hazard, no stroboscopic hazard, no blue light hazard, comfortable color temperature standards, slow light decay, and long life. , long-term protection of students’ visual health.

Practice is the only criterion for testing truth, and eye protection is the quality of walking. Over the years, Hongmai Optoelectronic educational lighting has blossomed all over the country; in 3,000+ schools and 100,000+ classrooms, students can explore comfortably in the mountains of books and the sea of ​​learning under the illumination of Hongmai Optoelectronic eye protection lamps.A pair of bright and clear eyes is the affirmation and satisfactory answer to Hongmai Optoelectronics.

Healthy lighting is not only a number that meets the standards of various parameters, but also a heavy responsibility on the shoulders. We will continue to move forward with responsibility and responsibility to support a bright future for children and teenagers!
