Straw Hat LED

Straw hat LEDs (also called helmet LEDs) flatten the emitting dome into a wide-brimmed lens that pushes the half-angle out to 120°–140° — nearly hemispherical coverage from a standard 5 mm, 8 mm, or 10 mm through-hole package. The result: uniform illumination of diffusers and light guides without secondary optics.QUEENDOM straw hat LEDs suit channel-letter backlighting, light boxes, instrument panel washes, decorative lighting, and anywhere a narrow-beam dome LED would leave hot spots. Colors include red, amber, yellow, green, blue, and white; diffused lens options further smooth output for close-range viewing. Because the lens sits flush at the package top, mounting height tolerance is generous compared with domed types. Intensity and wavelength bins are matched per lot, and every series passes 260 °C wave-solder qualification — full data in the DIP datasheet library.
