In recent years, the incidence rate of myopia among young people in China has been increasing. According to relevant statistics, the overall myopia rate of Chinese teenagers has exceeded 50%. Among the reasons that affect students' vision decline, in addition to Congenital heredity, the unsatisfactory lighting environment is a prominent problem. Therefore, how to improve the healthy lighting in the campus, gradually get attention.

Classroom as an important place for learning and activities, not ideal lighting environment will affect the vision of teachers and students. In the past, the key problems affecting the light environment health of classroom mainly focused on blue light, stroboscopic, glare and color temperature rendering.

Blue light and stroboscopic light are easy to cause vision damage, and induce many diseases, such as cataract, migraine and brain damage. Glare is one of the important causes of visual fatigue. The irrationality of lamp light distribution can easily reduce the visual condition of object visibility. The color temperature is an important index to improve the visual clarity. The light source in the classroom needs to reach 3300k-5500k color temperature to meet the standard of students' long-term focused learning.

Classroom lighting with healthy light source can create a healthy learning environment. In the face of the demand of improving educational lighting environment, OSRAM has always made great efforts to innovate, replacing traditional lamps with LED lighting with high color rendering, no harm of blue light, no glare, no stroboscopic, no radiation, long life and good energy-saving effect, creating a healthy and comfortable classroom light environment, and improving learning efficiency while protecting visual health.

Lighting upgrade helps modern teaching

Zhejiang Jinhua New Oriental bilingual school is a full-time school built by New Oriental Education Technology Group, which has a consistent system of education from kindergarten to high school. In order to create all kinds of complete modern teaching conditions for students, the school adopted the comprehensive and scientific intelligent campus design concept at the beginning of construction, and applied the brand-new lighting products with built-in OSRAM drive power supply products in classroom, multi-function hall and other indoor teaching scenes.

OSRAM follows the principles of health, intelligence, safety and easy maintenance to upgrade the classroom lighting in an all-round way. With the full support of lighting partner Zhongshan Raymond Lighting Electric Co., Ltd. and design partner tuojing lighting design, we create a reasonable lighting environment with high-quality light source design, further reduce the risk of eye fatigue and enhance students' attention, so as to bring students a pleasant and comfortable light environment.

Innovative products drive healthy lighting

In practical application, OSRAM's core component for lamps and lanterns, LED driving power supply, can manage lighting according to the situation and needs of classroom lighting and protecting students' eyesight health. Reasonable light environment output relies on the following two OSRAM driving power supplies: compact indoor driving power supply ot fit series (product model ot fit 40 / 220-240 / 1a0 CS) and the second generation of element 24 V constant voltage series driving power supply (product model element 180 / 220-240 / 24 G2) to help the lamps create a bright, comfortable, stroboscopic and healthy learning light environment and better protect the eyes.

At the same time, these two types of driving power supply also have high reliability, further optimize the maintenance cost, and realize the use effect of reducing cost and increasing efficiency. Next, let's learn more about their high quality performance.

Compact indoor driver——OT FIT series (product model OT FIT 40 / 220-240 / 1A0 CS)

The compact indoor drive power supply ot fit series (product model ot fit 40 / 220-240 / 1a0 CS) is a constant current LED power supply with a service life of 50000 hours and four adjustable output currents, which can better adapt to different lamps and provide high-quality light with different brightness. Ripple output is less than 5%, which can effectively protect students' vision. The exquisite compact size can be easily built into the lamp, which improves the flexibility of lamp design; it can also be used with cable clamp kit for external installation.

In the classroom lighting layout, it is often used in blackboard lamp, desk and chair lamp, and protection class I and II lamps.

The second generation of ELEMENT 24 V constant voltage series driver (product model ELEMENT 180 / 220-240 / 24 G2)

Its ECG efficiency is 91%, and its service life can reach 30000 hours. Its safety performance meets the requirements of IEC 61347-1, 61347-2-13, 62384 and other standards, with high efficiency and high reliability. At the same time, its output current ripple is less than 3%, and the light quality is good.

In the classroom lighting layout, it is suitable for indirect lighting such as hidden light belt.
