Court yard lamps are outdoor lighting fixtures designed to illuminate courtyards, pathways, and garden areas at night. The 'night view effect' refers to the visual appeal of these lights when they are illuminated in the evening. This effect can be enhanced by using different lighting techniques, such as color-changing LEDs, motion-sensing lights, and diffused lighting to create a warm, inviting, and safe atmosphere. The design and placement of the lamps are crucial in achieving a visually pleasing night-time environment.
