LED for outdoor signage display applications

The Hong series HNB503 SMD LED is smaller than the lamp LED components (dip type) that are usually used for outdoor signage application.

With its compact size, HNB503 is ideal for applications with limited PCB space in order to achieve compact packing density, and allows for brighter signage displays using LED technology.

It is customary for designers to choose red, green and blue lamp LEDs (dip type) as the light source for outdoor LED signage board because usual SMD packages are not designed for outdoor conditions such as moisture.

However, the pixel pitch of a lamp LED is always large with low density, which is only useful at longer viewing distances.

The Hong series HNB503 package is said to provide an ideal solution when users require a clear-view LED signage display with any size board with three-in-one full-colour SMD LEDs, which offer smaller pixel pitch between two LEDs to create a high-density and better-resolution LED display.

The HNB503 improves viewing of the signage from various angles with its 120deg viewing angle.

Everlight claimed the HNB503 is the only SMD package ideal for outdoor signage applications in moisture-sensitive environments.

Its package height of 4.0mm allows signage display manufacturers to more efficiently perform the glue process of their PCBs and seal against moisture.

The luminous intensity of the Hong series HNB503 is higher than general full-colour SMD LEDs in order to meet higher MCD requirements of the outdoor signage market.

HNB503 is produced with a black housing that can increase the contrast of the screen.
