What Makes Up an LED Linear Light?

LED linear light main structure

An LED linear light is an assembly of several key components. Each part plays a specific role — from heat dissipation to light diffusion to electrical connection.

Core components:

PC Diffuser Cover

Tampas finais

Mounting Accessories

Fita LED

Fonte de energia

Dimmer / Controller

Component Deep Dive

Aluminum Profile (6063-T5)

Lightstec usa aluminum alloy 6063-T5 for all linear light profiles. T5 tempering involves high-temperature extrusion, cooling, and artificial aging — producing a profile with excellent mechanical properties.

Why 6063-T5?

Good thermal conductivity (heat dissipation)
Lightweight yet rigid
Excellent extrusion — complex shapes possible
High mechanical strength and rigidity
Good machining performance

Surface finish:

Alkali-sand silver oxidation — a high-concentration alkali bath creates an ultra-smooth, corrosion-resistant surface with consistent color.

PC Diffuser Cover

Our diffuser covers are made from Polycarbonate (PC) — an engineering plastic with a carbonate ester polymer chain. Aromatic PC is the only type with industrial-scale production and is the fastest-growing engineering plastic.

PC cover advantages:

Heat resistant: up to 120–140°C
Fire rating: V2 (self-extinguishing)
UV resistant: excellent outdoor aging performance
Electrical insulation: stable even in wet/high-temp conditions
Light diffusion: uniform, glare-free output

Tampas finais

End caps seal both ends of the linear light, protecting the internal components and giving a clean finished look.

Available materials:

PC (polycarbonate) — lightweight, insulating
Aluminum — matches profile color, premium look

Lightstec Note: Aluminum end caps are color-matched to the profile for a seamless, professional finish.

Mounting Accessories

Every linear light needs hardware for installation. Lightstec provides a complete accessory kit with each product.
