Detailed classroom LED lighting design (two)

2, lamps

What is a grille lamp, with a cover bracket, a dedicated blackboard light? Please look:

Figure: This is an embedded grille lamp for ceiling ceiling.

Figure: This is a bright or suspended grille lamp, suitable for ceiling without ceiling.

If you have money, you can also use semi indirect lighting lamps, the effect is better on the high oh! Please return to the top, look at the title picture, lighting effect that is semi indirect lighting.

Figure: This is a cover bracket, the same applies to ceiling without ceiling.

Figure: This is a special blackboard light, you can adjust the direction of irradiation. Recommended distance from the wall 0.3~0.6 meters.

3, lamp spacing

Why is this interval determined 2.8m-3m? Because of the spacing of the use of 2x28W T5 fluorescent lamp, illumination is about 300~350 LX, in line with the requirements of the national standard of 300 lx.

We use the tall DIALux Evo software to simulate the spacing of the lighting situation:

Figure: DIALux Evo simulation results, lighting power density value of 9W/m2, in line with national standards.

4, layout direction

Why should the longitudinal line of sight? The main problem is to consider the glare, so that the layout of the smaller glare.

5, control switch

Q: why rely on a row of windows need independent control?

Answer: white sky class, you can turn off the window lights, make full use of natural light, energy conservation oh!

Q: why do the front lamps need to be independently controlled?

Answer: now the classroom is equipped with the projector, the projector, to turn off the front row of lights, in order to see oh.

Q: why should the blackboard light be controlled by the left and right halves?

Answer: the same is the cause of the projector! General projection screen will be placed aside, leaving the other side of the teacher to write chalk. That's all we have to do.
