会社のニュース LED Application Scenarios in Slim Design: How the 020 RGB Side-View LED Saves 4mm of Product Thickness

Ask a product designer what limits industrial design more than battery or PCB space, and many will answer the same thing: the height of the light source. Every millimeter of an LED package becomes a millimeter of bezel, and bezel is what consumers see first. That is why side-emitting parts are quietly reshaping LED application scenarios across consumer electronics and lighting.

Four LED Application Scenarios Built Around Thin Light Guides

• Ultra-slim RGB strips — cove lighting and TV bias lighting built into 5 mm channels
• Appliance front panels — mode rings and level bars behind injection-molded guides
• Automotive trim lighting — door and dashboard light lines with no visible hot spots
• Wearables & handhelds — status indication in housings thinner than 8 mm

Featured Model: 020 RGB Side-View LED (3.8 × 1.0 × 0.64 mm)

The 020 RGB side-view LED solves the thickness problem by emitting sideways rather than upward. At just 0.64 mm tall — roughly the thickness of a credit card edge — it couples light directly into a polycarbonate or PMMA light guide, so the visible bezel is set by the guide, not by the LED.

Inside the package sits a full-color RGB die set with independent channels. With 160 / 550 / 110 mcd output at a modest 20 mA, the part mixes to clean white as well as saturated red, green and blue — which is exactly what modern ambient-lighting products demand when they cycle through scenes, alarms and standby states.

Why Side Emission Beats Top Emission Here

• Removes hot spots — edge coupling lights the whole guide evenly, so a 600 mm strip shows one continuous line instead of dots.
• Allows thinner bezels — 0.64 mm height frees roughly 2–4 mm of stack height versus standard top-view RGB packages.
• Protects the color — tight 466–472 nm blue and 515–525 nm green bins keep mixed whites from drifting pink or green across a batch.
• Same reel, more designs — one part covers cove strips, appliance panels and automotive light lines, simplifying inventory for multi-product factories.

Practical Notes for Your Next Build

For a 60-LED/m RGB strip, run the 020 part at 20 mA per channel and specify a 2 mm guide with a matte diffusion layer — measured uniformity stays inside ±10% along the run at 300 mm from the wall. For appliance panels, reserve 1.2 mm of guide thickness so mode colors remain distinct at a 45° viewing angle. For automotive trim, the −40°C to 85°C rating and RoHS / REACH compliance cover the documentation most OEMs request at RFQ stage.

These side-view parts are produced by Dongguan Lanjin Optoelectronics Co., Ltd., a manufacturer established in 2005 with more than 18 years of SMD packaging experience. Lanjin builds top SMD LED, side view SMD LED, through hole LED, bi-color and RGB SMD LED, IR and UV LED chips, 7-segment displays, high power LED chips and SMD LED PCBA — using San'an and Epistar chips with 99.99% pure gold wire bonding and 500KK pieces of monthly capacity.
