Farvemikser, 3 forskellige LED lamper Rød, Grøn og Blå

This set contains three LED light sources - red, green, and blue. It is designed specifically for hands-on demonstrations in geometric and color optics. Each LED source comes with a removable attachment that narrows the beam into a thin light line, making the set suitable for experiments involving light rays, reflection, and refraction. The LEDs without the attachment produce a wide, expanding beam, enabling clear demonstrations of color mixing. By directing the colored beams onto a surface students can observe additive color blending. The set also works exceptionally well for shadow-based color experiments, where illuminating a small object with all three beams creates colorful and visually engaging shadow patterns. Light sources cointain magnetic foils for attaching on the magnetic boards.
