LED downlights, tubes and other LED lighting fixtures for classrooms can effectively prevent myopia! ||

With the continuous development and progress of mankind and technology, lighting led by LED downlights and LED grid lights has become an indispensable and important part of people's lives. The school is a place to train future talents. The myopia of students is getting worse, and the trend of younger age is on the rise! So how to use LED downlights, tubes, LED grid lights and other LED lighting fixtures to create a reasonable and efficient lighting environment to alleviate this situation? The latest statistics show that the incidence of myopia in my country's population is %, and the number of myopia in the country has reached nearly 100 million, which is twice the world average %. The myopia rate ranks first in the world. As early as 2000, a survey conducted by the National Bureau of Statistics showed that the proportion of myopia among primary school students in my country was %%, that of junior high school students was %, and that of key high school students was about %. Even fewer college students had qualified eyesight! In addition to congenital hereditary factors, students’ myopia also involves prolonged reading, incorrect writing posture, overburden in class, etc., and lack of adequate rest and adjustment, resulting in excessive eye fatigue. Students spend a lot of time in school, so low lighting in school classrooms and other spaces is also the main cause of myopia. , Design standards and interior layout For classroom lighting, according to the current architectural lighting design standard [GB-], the daylighting coefficient of school classrooms should not be less than %. In order to improve the lighting effect of the classroom, the indoor surfaces should be high brightness Low-color decoration. For classroom lighting, the national standard requires the average illuminance of the classroom desktop to be lx, and the uniformity of illuminance is not less than; the classroom blackboard should be equipped with local LED lighting fixtures, and the average vertical illuminance is not less than lx. , Lamp selection and layout The lamp plug-in is provided through DIALuxevo software. After design, two options of ×W embedded grille lamp and LED grille lamp W are selected to replace the old-fashioned halogen powder double-tube bracket before the transformation to compare the lighting effects. Start the software calculation plan 1 × WT double-tube grille lamp calculation results, see the vertical illuminance lamp selection of the classroom blackboard The photoelectric blackboard light control glare is set according to the above figure, the blackboard vertical average illuminance data table plan two LEDW grille The final calculation results of the lamp are obtained. The calculation results and design content are discussed. After DIALux software simulation, the average illuminance of the solution 1 using T×W embedded LED grid lights is lx, and the average illuminance of the second solution using LEDW embedded LED grid lights is lx , The average illuminance of the blackboard lamp is lx, all of which meet the requirements of relevant national standards. Reasonable use of the protection angle of the lamp and embedded installation, very effective control of the effect of glare, while improving the overall average illuminance to ensure the uniformity of the classroom environment, while effectively reducing the surface reflection of the working surface, writing materials, office appliances and other surfaces used to create comfort The lighting environment. Energy-saving lighting solutions and control devices can not only change the poor lighting environment, but also promote the development and application of high-efficiency energy-saving light sources and LED downlights, LED grid lights, tube lights and other LED lighting fixtures. Let students be in a comfortable lighting environment, thereby inspiring students' enthusiasm for learning! Introduction Optoelectronics focuses on lighting design, production and construction, providing overall solutions for LED lighting projects such as airports, hotels, commerce, and offices, and is the designated lighting supplier for major domestic airports. ---Contact address: Lighting selection website on the floor of Changhong Science and Technology Building, Science and Technology Park, Nanshan District, Shenzhen
