What kind of light are the lights in the classroom? What is the smart light in the classroom?
The straight tube fluorescent lamp (also called fluorescent lamp) most commonly used in the early traditional classrooms generally had thicker and finer ones according to the number of W, and the length also had various lengths according to the power. The power has a variety of specifications with the equation of 8W~100W. But why do classrooms now need to be transformed and replaced with special classroom lights and blackboard lights?
Originally, in 2018, eight departments including the Ministry of Education issued a notice on the "Comprehensive Prevention and Control of Myopia in Children and Adolescents", requiring "100% compliance rate of school classroom lighting hygiene standards". People began to realize the importance of a healthy and green classroom light environment. Knowing the deficiencies and lighting effects of traditional classroom fluorescent lights, we have summarized the following five points:
1. The fluorescent lamps commonly used in traditional classrooms choose fluorescent lamps with low quality, low price, high energy consumption, and technical level stuck in the 80s and 90s of the last century.
2. There is no special blackboard lamp designed. If ordinary classroom fluorescent lamps are used as blackboard lamps, not only the classroom blackboard has low light intensity and low visibility, students will see the direct dazzling of the lamps when they look at the classroom blackboard. Light can easily cause visual fatigue.
3. Inductance ballasts are used for special lamps in many classrooms, and there are serious stroboscopic phenomena.
4. And most lighting fixtures use soft hanging, and the electric fan is installed on the top of the lighting fixture. When the electric fan and the lighting are turned on at the same time, there will be a serious situation of lamp swing and lighting shaking.
5. Many lighting fixtures use fluorescent lamps with high LED color temperature (6500K) and cold light colors. The light source is too pale and stiff, which can easily lead to visual fatigue and emotional excitement of students.
According to the classroom lighting standards issued by the country, classrooms use LED eye protection classroom lights that meet the national standards to have six standards: excellent illumination, no glare, high color rendering index, no light stroboscopic hazard, moderate color temperature, and no blue light hazard. .
The biggest advantage of LED classroom lights (electroplating grille) is low glare. Through professional optical design, the light-emitting surface of LED classroom eye-protection grille lights adopts a small grille. The glare value UGR is controlled below 16, so that the light is not visible, which greatly reduces the glare, improves the comfort of the eyes, and protects the eyesight of students.
In addition, the LED grille classroom lamp is light-transmissive on the back to realize that the lamps can emit light up and down. The top of the classroom will also have a certain illuminance. The entire classroom has good light transmission from the top and bottom, and there will be no obvious contrast between the upper and lower light and dark, which improves the entire classroom. The light environment is comfortable and light transmittance, and the light is soft, close to the color of daylight, which can effectively protect the eyesight of students and avoid visual discomfort and fatigue. Improve the light environment of the entire classroom.
More adjustable intelligent classroom lights: the new adjustable intelligent classroom lights can be divided into class mode, projection mode, activity mode, self-study mode, examination mode and class meeting mode. Each mode can adjust and switch the brightness of a single lamp or the whole according to different scenes. After professional design, the arrangement and setting of lamps can fully meet the requirements of relevant national illumination standards.
The classroom LED grille lights have no obvious impact on the strobe, the exempt RGO has no blue light hazard, the color rendering index is not less than 90, and the color temperature is controlled at about 5000K, which improves space comfort and reduces blue light damage.
The classroom special blackboard lamp has a curved anti-glare shading plate design. The anti-glare shading plate should be integrally formed with the main body of the lamp. The length of the anti-glare shading plate is 1200mm≤the length of the anti-glare shading plate≤1210mm, and the chord length of the arc anti-glare shading plate ≥25mm; The polarizing lens designed with precision optical light distribution is made of high-transmittance PC, and the length of a single lens is greater than 275mm. The installation distance of the blackboard is less than 35CM, which can reduce the glare of the teacher, and the glare value is lower than 10
