I still remember that when I was studying, the lights in the classroom stayed in the era of fluorescent lights. The dim light and the full-screen notes made people sleep.
Is this the reason why you didn't study hard in the past?
What I want to say is that classroom lighting often affects learning, and the blackboard is a part of the classroom full of dry goods. The role of lighting is even more self-evident.
In public places such as schools, in addition to the illumination requirements of classroom desks, classroom blackboard positions also have clear lighting standards.
In the "Architectural Lighting Design Standards" GB 50034-2004, it is mentioned that the illumination of the blackboard surface of the classroom blackboard needs to reach 500lx, and the color rendering index of Ra should reach 80.
The standard value of the illuminance of the blackboard position needs to reach 500lx. If the lighting of the classroom environment alone is used, the blackboard surface may not meet the illuminance standard, so the general blackboard needs to be equipped with special lighting.
Today, I introduced a linear wall-washing blackboard lamp, which is called a small blackboard lighting expert.
The pursuit of simplicity, modernity and linear style is the perfect interpretation.
Silver-gray metal texture, smooth and simple lines, modern and simple space feels.
Uniform light output, brightness uniformity up to 0.85
As a small blackboard lighting expert, it is a polarized light distribution lens designed and developed independently for blackboard lighting, which makes the exiting light and the LED light source axis direction produce a deflection angle.
Allows the entire blackboard to form a perfectly uniform brightness distribution with a brightness uniformity of 0.85.
The performance of the blackboard light in space makes people feel comfortable:

Really light color performance, uniform without dark areas:

The DIALux simulation application of the blackboard light in the classroom, the lamp is 450mm away from the blackboard, the height of the ground is 2800mm, and the average illumination of the 3 lamps reaches 659lx. The effect is as follows:
Side view light distribution
Blackboard average illumination 659lx
Excellent light, care for the eyes
As a blackboard light, it uses a custom ultra-high-brightness patch LED light source, using an exempt level blue-free hazardous LED chip to ensure the purity and quality of the light color.
Super bright brightness lamp beads
In the light source data of the illuminated passport, the color rendering index CRI=94, R9=81, only 1% strobe.
CRI=94, high color rendering ensures color reproduction. In high PF high-performance power supply, the lamp has only 1% stroboscopic percentage. Almost no stroboscopic light can avoid headache and eye fatigue, leading to decreased vision and distraction. problem.
Therefore, the appearance of this lamp, whether it is a little excuses for the little friends who went to sleep in class that year.
