7070 High-Power Ceramic LED Chips — Industrial-Grade Illumination for Demanding Environments

Product Overview

QUEENDOM’s 7070 High-Power Ceramic LED Chips deliver exceptional optical output in a robust 7.0mm × 7.0mm ceramic package, designed for applications where raw luminous power and thermal resilience matter more than compact size. With thermal resistance below 2.0 K/W and luminous efficacy exceeding 180 lm/W, these chips power the most demanding industrial and outdoor lighting installations.

The 7070 form factor accommodates larger semiconductor dies and advanced thermal vias, enabling sustained operation at 5W, 10W, or even 15W per chip without junction temperature derating. This makes the 7070 the platform of choice for high-bay industrial lighting, sports floodlighting, tunnel illumination, and large-format architectural projection where metal-halide and HPS replacements are targeted.

Key Applications

High-Bay Industrial Lighting

Warehouse and factory lighting at 8-15 meter mounting heights requires high-lumen output with wide beam distribution. Our 7070 chips deliver 1500-3000 lumens per chip, enabling 100W-200W LED high-bay fixtures that replace 400W metal-halide lamps with 50% energy savings and instant-on capability.

Sports Arena and Stadium Floodlighting

Professional sports lighting demands uniformity ratios >0.7, glare control (GR<50), and color rendering >Ra70 for broadcast compatibility. The 7070’s high output and tight binning enable precision floodlight arrays that meet FIFA, IAAF, and broadcast standards for 4K HDR capture.

Tunnel and Underpass Illumination

Tunnel lighting must adapt to rapid luminance transitions from bright daylight to dark interior. 7070-powered LED fixtures with intelligent dimming deliver consistent roadway illumination while withstanding exhaust fumes, humidity, and vibration. The ceramic substrate resists corrosion from salt spray and automotive exhaust chemicals.

Large-Format Architectural Projection

Building facade projection mapping and landmark illumination require high optical density from compact source arrays. Multiple 7070 chips in dense COB arrays create powerful, color-mixing sources that rival traditional discharge lamps while offering DMX color control and 100,000-hour lifespans.

A: At 10W with thermal resistance <2 K/W, junction temperature rise is approximately 20°C above heat sink temperature. For Tj<105°C in 40°C ambient, a heat sink with thermal resistance <4.5 K/W is sufficient — typically an aluminum extrusion with 50-80 cm² surface area. We provide thermal simulation files and can recommend specific heat sink models for your mechanical constraints. Q: Can the 7070 chips be used in series arrays? A: Yes. The high-voltage design (34V-38V) is optimized for series strings of 10-20 chips driven by standard 350V-400V DC constant-current drivers. This architecture minimizes driver cost and improves system efficiency compared to low-voltage parallel arrays. We provide series/parallel wiring recommendations and driver selection guidance. Q: What is the difference between standard and premium CRI bins? A: Standard bins deliver Ra > 70 with R9 (red) > 0, suitable for industrial and outdoor applications. Premium bins achieve Ra > 80 with R9 > 50, required for retail, hospitality, and broadcast applications where color accuracy is critical. Premium bins have tighter color consistency (3-step MacAdam) and are priced approximately 15-20% above standard bins.

Q: Do you offer chip-on-board (COB) assemblies using 7070 dies?

A: Yes. We manufacture custom COB arrays integrating multiple 7070 dies on ceramic or metal-core PCBs, with integrated lenses, reflectors, and thermal interfaces. COB solutions simplify assembly for fixture manufacturers and improve optical consistency. Minimum order for custom COB is typically 500 units with 6-8 week lead time.

Q: How do I select the right driver for 7070 LED arrays?

A: Driver selection depends on: total LED string voltage (number of chips × Vf), target current, dimming method (0-10V, DALI, DMX, or PWM), and input voltage (AC mains or DC). We provide driver compatibility matrices and can recommend specific models from leading manufacturers (Mean Well, Inventronics, Osram/Tridonic). For large projects, we offer custom driver design with your specified form factor and control interface.
