Low cost ultra white 7 segment led display module for kitchen hood /range hood
Product Overview
Introducing the Low-Cost Ultra Bright White 7-Segment LED Display Module—a budget-friendly, high-performance numeric solution engineered specifically for kitchen hood (range hood) controllers. Designed to deliver clear readouts of core hood functions—fan speed (e.g., "3" for high speed), timer values (e.g., "15min" for auto-shutoff), or filter cleaning alerts (e.g., "CLN")—this module balances affordability with reliability, making it ideal for mass-produced home appliances.
Its 0.5-inch (12.9mm) digit height ensures readability from kitchen counter distances (1–2 meters), while the slim 92.5×17.5×11.2mm form factor fits seamlessly into compact hood control panels. The white segments on a black surface, enhanced by a yellow diffused film, eliminate glare from kitchen lights and evenly distribute light across each segment—critical for quick, distraction-free checks while cooking. With common cathode polarity, low power consumption, and RoHS compliance, it integrates easily into hood circuits and meets global environmental standards—all at a cost that supports high-volume appliance production.

Key Features (Kitchen Hood-Optimized)
1. Affordability Without Compromise
Low-Cost Design: Streamlined manufacturing processes reduce costs for mass production, making it ideal for budget-friendly and mid-range kitchen hood brands—without sacrificing performance or durability.
No Hidden Expenses: Compatible with standard sockets and PCB layouts, so manufacturers avoid costly custom circuit redesigns or specialized mounting hardware.
2. Kitchen-Proof Visibility & Glare Reduction
Ultra Bright White Illumination: 100-120mcd luminous intensity and 0.29-0.31 (X/Y) chromaticity (pure white light) cut through kitchen glare—from overhead pendant lights, under-cabinet LEDs, or sunlight through windows—ensuring digits are visible even while stirring or sautéing.
Yellow Diffused Film: The film evenly distributes light across segments, eliminating "hot spots" and softening harsh glare—critical for avoiding eye strain during prolonged cooking sessions.
White Segments on Black Surface: High contrast ensures digits (e.g., "2" for medium fan speed) stand out against dark hood control panels, even in dim kitchen corners.
3. Easy Integration & Durability
Common Cathode Polarity: Works with standard kitchen appliance driver ICs (e.g., TM1637, HT1621) commonly used in hood controllers, simplifying circuit design and accelerating production.
Dual Mounting Options: Easy installation on both PC boards and sockets—supports automated assembly lines for high-volume hood manufacturing, reducing labor costs.
Stable Performance in Kitchen Conditions: Withstands temperature fluctuations (0°C–50°C, typical kitchen ranges) and minor grease/steam exposure (protected by the module's sealed housing), maintaining consistent brightness over time.
4. Energy Efficiency & Longevity
Low Power Consumption: 2.8-3.3V forward voltage and 12-15mA/LED forward current minimize energy draw—aligning with energy-efficient home appliance standards (e.g., ENERGY STAR) and reducing long-term electricity costs for users.
Long Lifetime: High-quality LED chips ensure a typical lifespan of 50,000+ hours—matching the 8–10 year service life of most kitchen hoods, so users rarely need replacements.
