4mm LEDs

4mm DIP LEDs – High Brightness, Full Color Range & Multiple Viewing Angles

Overview

QUEENDOM 4mm LED is a 4mm LED diode product in a circular through-hole LED DIP package, also known as a T-1 (4mm) LED. The outer diameter of 4mm led lights is 4mm. It meets the needs of electronic products, instruments and equipment. Supplied in flanged (with-flange) and flangeless (no-flange) package options for secure panel and PCB mounting or height-constrained designs, QUEENDOM 4mm LED diodes are a drop-in through-hole light source for indicator and backlighting designs.

The 4mm LED series covers the full color range — blue 465 nm, green 505/530/550/575 nm, yellow 590 nm, orange 605 nm and red 624 nm — plus white LEDs with CCT from 2200 K to 10500 K, in water clear, colored clear, white diffused and colored diffused lens types. Every part number is ranked individually so brightness and chromaticity bins stay consistent from lot to lot.

Benefits

Excellent heat dissipation design: Use low Rth materials for effective heat dissipation design to improve efficiency. Thermal color positioning ensures colors are within the ANSI bin range at 85°C.

Good color uniformity: Colored light adopts 2.5nm binning structure, warm white light 200k/PIN, and pure white light 500k/PIN, which ensures excellent color uniformity.

Tight rank structure (THLR40201 – THLR40344) delivers consistent brightness and chromaticity binning across production lots

Standard 20 mA drive current, directly compatible with 3 V, 5 V and 12 V logic and constant-current LED driver circuits

Long solid-state service life with low maintenance cost
