Some of the special needs in children that have been increasingly common lately and for which learning through light could be beneficial include:  

1. Autism Spectrum Disorder (ASD)  

- Children with ASD may benefit from well-structured visual stimuli, as they often respond better to visual information than verbal cues.  

- The use of interactive lights and colors can help with emotional regulation and attention.  

2. Attention Deficit Hyperactivity Disorder (ADHD)  

- Light-based games can capture and sustain attention, helping these children focus on specific tasks.  

- Proper lighting can reduce sensory overstimulation.  

3. Visual Impairment (Low Vision or Partial Blindness)

- Light and shadow contrasts can enhance the perception of shapes and objects.  

- Technologies like backlit screens or light boards can facilitate reading and writing.  

4. Intellectual Disability  

- Light can be used to reinforce basic learning, such as associating colors with objects or actions.  

- Interactive light games can stimulate motor skills and cognition.  

5. Sensory Processing Difficulties

- Light therapy can help regulate sensory responses in children with hypersensitivity or hyposensitivity to visual stimuli.  

- Controlled lighting environments can promote calmness and improve concentration.  

6. Photosensitive Epilepsy (with caution)

- In some cases, certain forms of light can be helpful, but it is crucial to avoid visual stimuli that may trigger seizures.
