At InfoComm 2026, miniaturized packaging technologies such as COB, MIP, and Mini LED took center stage. Yet amid the wave of "smaller pitch," DIP packaging still drew the attention of professional visitors in dedicated exhibition areas.
As the earliest LED packaging form, DIP lamp beads have witnessed the complete evolution of the industry from through-hole to surface mount. While SMD, Mini LED, and Micro LED each dominate their respective tracks, DIP has not faded away — instead, it continues to prove its irreplaceability in specific fields. Where will this "venerable" technology go in the next decade?
The core competitiveness of DIP lamp beads stems from the fundamental advantage of their physical structure. Unlike SMD lamp beads, where chips are mounted directly on the PCB surface, DIP lamp beads feature an independent sealed structure fully encapsulated in epoxy resin, with metal pins passing through the PCB for soldering.
The direct value of this structure is particularly evident in extreme environments:
· ��️ In hot deserts: Metal pins conduct heat directly, reducing chip junction temperature by 5-10°C compared to SMD, with stable operation above 50°C
· �� In coastal high-salt areas: Full epoxy encapsulation effectively isolates chloride ion corrosion — no pin rust, no circuit short circuits
· �� Along high-vibration highways: Through-hole soldering provides far superior mechanical strength to surface mount — millions of lamp beads remain intact
�� Test Data: Kingaurora DIP lamp beads show less than 15% brightness decay within 5 years, supporting 8-10 years of ultra-long stable operation, delivering irreplaceable asset value preservation in heavy-duty outdoor scenarios.
The challenges facing DIP lamp beads are equally significant. The continuous evolution of SMD technology toward higher definition and thinner profiles is steadily compressing DIP's market space.
· Physical pixel pitch limits: DIP lamp bead products are primarily concentrated at P10 and above; the P6 and below HD outdoor screen market is dominated by SMD
· Inherent viewing angle disadvantages: DIP offers about 110° viewing angle while SMD reaches 140°-160°, making SMD superior in multi-angle viewing scenarios
The future of DIP lamp beads lies not in competing with SMD on pixel density, but in defending the "reliability" moat. Several trends deserve attention:
· Global warming — Extreme heat events are increasing; SMD faces heat dissipation failure above 50°C, while DIP's natural cooling advantage becomes more prominent
· Landmark media transformation — High-rise buildings, glass curtain walls, and naked-eye 3D screens demand high wind resistance, lightweight design, and long lifespan
· Total Cost of Ownership (TCO) awareness — 8-10 years of maintenance-free operation and over 30% energy savings deliver far greater long-term value than SMD
The evolution path for DIP lamp beads over the next decade is becoming clear:
· Intelligent integration — Built-in sensors monitor each lamp bead's status in real time, enabling the upgrade from "passive durability" to "predictive maintenance"
· Deep scenario customization — Developing specialized DIP products for offshore platforms, explosion-proof zones, and super-tall buildings to build differentiated competitive barriers
�� Conclusion
The next decade for DIP lamp beads holds both opportunities and challenges. It will not compete with SMD across all domains, but in "heavy-duty" areas where safety matters, where equipment must withstand nature's tests 24/7, and where ultra-low total cost of ownership is paramount, DIP remains the undisputed champion.
As Kingaurora's 17 years of dedication have shown — the value of technology lies not in being the "newest," but in being the "most suitable." Doing the right thing in the right place — this path is equally broad.
