Directlit

Direct-lit describes a lighting arrangement in which the luminaire emits light directly toward the area to be illuminated, with little or no diffusion. It contrasts with indirect lighting, where light is directed at ceilings or walls to be reflected into the space. Direct-lit tends to deliver higher illuminance on the target surface.

In architecture and interior design, direct-lit fixtures typically point downward or toward a task plane, using diffusers or louvers to control glare. The approach yields strong, focused illumination and crisp shadows, and is common for work areas, retail displays, and museums. It can require careful placement to avoid hotspots.

In display technology, direct-lit backlighting describes LEDs positioned directly behind an LCD panel rather than along the edges. This full-array arrangement can provide more uniform brightness and enables local dimming, improving contrast on larger screens. Direct-lit displays are often contrasted with edge-lit designs.

Pros include higher brightness, better color consistency, and improved dimming control; cons include greater thickness, higher cost, and potential hot spots if the array is not well engineered.
