LED Ring Light: Video Streaming Build Under Rs.500

Ring lights are the secret behind professional-looking video calls, YouTube content, and Instagram photos. The circular shape creates even, shadow-free lighting with an attractive catchlight in the eyes. Commercial ring lights cost Rs.1,500-5,000, but you can build one for under Rs.500 using WS2812B LEDs and a 3D-printed or cardboard frame.

Why Ring Lights for Video

• Even, shadow-free illumination: The circular shape wraps light around the subject
• Attractive eye catchlights: Creates the distinctive ring reflection in pupils
• Flattering for faces: Minimises skin texture and shadows under eyes
• Compact and portable: Easy to mount behind a phone or camera

Design Options: WS2812B vs White LEDs

• WS2812B ring (24 or 60 LEDs): Full RGB colour, animated effects, controlled with Arduino. More expensive but infinitely versatile.
• White LED strip in a circle: Simpler, cheaper, just needs a dimmer. Best for pure lighting.
• Pre-made WS2812B ring boards: Available in 12, 16, 24, and 60 LED sizes. Rs.60-200.

Building the Ring Structure

Options for the ring frame:

1. 3D printed: Design a ring with LED mounting groove. Best quality.
2. Cardboard: Cut two concentric circles from thick cardboard. Free and quick.
3. Wire hanger: Bend into a circle and mount LEDs with hot glue.
4. Embroidery hoop: Available at craft shops for Rs.50-100. Perfect diameter.

Target diameter: 25-30 cm for phone use, 35-45 cm for camera/streaming.

Diffusion for Flattering Light

• Wrap the ring in white tissue paper or tracing paper
• The diffusion converts point-source LEDs into a soft, continuous glow
• Without diffusion, you get individual LED spots in eye reflections
• With diffusion, you get a beautiful smooth ring catchlight

Dimmer and Colour Control

#include <Adafruit_NeoPixel.h>
#define NUM_LEDS 24
Adafruit_NeoPixel ring(NUM_LEDS, 6, NEO_GRB);

void warmWhite(int brightness) {
  for(int i=0; i<NUM_LEDS; i++)
    ring.setPixelColor(i, ring.Color(brightness, brightness*0.8, brightness*0.5));
  ring.show();
}
void coolWhite(int brightness) {
  for(int i=0; i<NUM_LEDS; i++)
    ring.setPixelColor(i, ring.Color(brightness, brightness, brightness));
  ring.show();
}

Phone and Camera Mount Integration

• Mount a phone clip or camera cold shoe at the centre of the ring
• The camera looks through the ring, creating perfectly centred lighting
• Use a standard tripod thread (1/4 inch) on the back for stand mounting
• For desk use, a flexible gooseneck arm is ideal

Power Options: USB and Battery

• USB powered (5V 2A): Plug into any USB adapter or laptop. Simplest option.
• USB power bank: Portable for on-location shooting
• 18650 battery: Most compact, 2-4 hours runtime

24 WS2812B LEDs at moderate brightness draw about 500 mA — any USB port can handle this.
