Key Features (Oven Timer-Optimized)
1. High-Temperature Resilience for Kitchen Appliance Environments
+105°C~+120°C Max Operating Temp: Engineered with heat-resistant epoxy encapsulation and SMD LED chips, it withstands the extreme ambient heat inside oven control panel enclosures—no dimming, flickering, or segment failure during prolonged baking/roasting cycles. This heat resistance far exceeds standard LED displays, making it a dedicated solution for cooking appliances.
SMD Pin Design: Supports automated SMT production lines, reducing assembly time and labor costs for high-volume oven and gas cooker manufacturing. The surface-mount structure also enhances thermal conductivity, further improving heat dissipation in tight appliance enclosures.
2. Kitchen-Optimized Visibility for Timer Countdowns
Ultra Bright White/Blue + Black Face Contrast: Eliminates glare from kitchen overhead lights and oven interior illumination, ensuring timer values are crisply readable from 1–2 meters. White light delivers neutral, eye-friendly readability, while blue light offers a modern, premium aesthetic for high-end smart ovens.
Big Viewing Angle: Delivers clear visibility from side positions—users can check remaining cooking time without leaning over hot cooktops or opening oven doors, improving kitchen safety and convenience.
Good Batch Consistency: Uniform brightness and color temperature across production batches ensure consistent display appearance across all oven models, enhancing brand image and user trust.
3. Energy Efficiency & Long-Term Reliability
Low Power Consumption: Minimizes energy use for oven timer systems that run intermittently during cooking cycles, aligning with global home appliance energy-saving standards and reducing household electricity bills.
Long Lifetime: High-quality LED chips match the 8–10 year service life of built-in ovens and gas cookers, eliminating frequent display replacements and reducing maintenance costs for homeowners and appliance manufacturers.
Stable Performance: Resists voltage fluctuations from kitchen power grids and electromagnetic interference from oven heating elements, ensuring glitch-free countdown operation for every cooking cycle.
4. Manufacturer-Friendly Integration & Versatility
Common Cathode IC Compatibility: Works seamlessly with mainstream timer driver ICs and oven control microcontrollers. Simplifies circuit design for countdown functions, time adjustment, end-of-cycle alerts, and brightness tuning for day/night use.
Multi-Color Customization: Optional emitting colors enable functional coding for different oven modes:
Red: High-visibility for fast preheat timer countdowns and overheat alerts
Amber: Warm tones for slow roasting and baking cycles
Green: Normal operation status for keep-warm timer functions
