1. General Information and Usage Guidelines

This section outlines the catalog’s scope as of February 2014, emphasizing Nichia’s LED product range for general electronic equipment. It prohibits unauthorized reproduction, reverse engineering, and disassembly. Users are cautioned against direct prolonged viewing of high-output LEDs due to eye safety risks. Specifications may change without notice, and formal agreements are required before mass production to ensure warranty validity. All products comply with RoHS and support lead-free soldering.

2. Product Identification and Classification

LED products are classified mainly into Surface Mount and Lamp Types, with detailed identification codes covering chip type, color, package, and revision. Colors span White, Warm White, Blue, Green, Red, Amber, Full Color, and UV. Chip On Board (COB) types and lens characteristics (color, diffusion, directivity) are also encoded for precise product selection.

3. Product Lineups and Features

The catalog presents Nichia’s LED offerings across multiple applications:

• General Lighting: High color rendering LEDs (Ra ~90, R9 ~50) with color temperatures from 2000K to 8000K, suitable for bulbs, downlights, tubes, panels, signage, and cove lighting.
• Specialty Lighting: Lamp and surface mount LEDs with detailed chromaticity and luminous intensity data.
• Display and Automotive Lighting: LEDs tailored with specific chromaticity and luminous flux/intensity for these sectors.
• UV LEDs: High-power surface mount and lamp types with optical power and spectral data for curing and excitation applications.
• New series such as 757D-V1 and X19B-V1 highlight high luminous efficacy (up to 175 lm/W at 1W) and compact packages.

4. Technical Specifications and Parameters

Comprehensive data includes luminous flux, forward voltage, luminous efficacy, forward current, color rendering indices (CRI), and chromaticity coordinates to ensure color quality and consistency. Package dimensions, packing examples, and handling precautions are detailed for both surface mount and lamp types.

5. Handling and Usage Recommendations

The document also provides contact details for Nichia’s global sales offices and subsidiaries, demonstrating international presence.

7. Detailed Product Specifications and Applications

This section elaborates on Nichia’s LED types with focus on:

• Surface Mount LEDs: Small, thin, high-efficacy LEDs with various CRI options and drive currents.
• 3-in-1 LEDs for HD Displays: Ultra-compact packages enabling high-resolution indoor displays.
• High Power UV LEDs: Inorganic packages for high reliability in curing and excitation applications.

Electrical and optical characteristics such as luminous flux, forward voltage, current, and color temperature are specified with tolerances. Packaging and mounting methods (primarily reflow soldering) are described, including maximum packing quantities.

8. Color Rendering, Chromaticity, and Ranking

Color ranks (e.g., R70, R80, R85, R90) and chromaticity coordinates (x, y) are provided with measurement uncertainties (±0.005 to ±0.012). Blackbody locus references assist in color temperature positioning. Warm white LEDs are detailed with specific ranks and chromaticity data. Users are advised to consult Nichia sales for rank selection to ensure color consistency.

9. Limitations, Ratings, and Best Practices

• Absolute maximum ratings for forward current, power dissipation, junction and storage temperatures are specified.
• Pulse width (≤10 ms) and duty cycle (≤1/10) limits are recommended to prevent damage.
• Thermal management guidelines emphasize maintaining junction temperature within safe limits.
• ESD precautions are mandatory to prevent device damage.
• Soldering conditions include preheat, peak temperature, and maximum reflow cycles, with nitrogen atmosphere preferred.
• Cleaning recommendations favor isopropyl alcohol; ultrasonic cleaning is discouraged unless validated.
• Eye safety standards (IEC 62471) classify LEDs by photobiological risk; high-power blue LEDs may pose eye hazards.

10. Mechanical Dimensions, Packaging, and Handling

Detailed mechanical outlines with tolerances (±0.1 to ±0.3 mm) are provided for surface mount and lamp LEDs, including polarity markings and heat sink structures. Packaging methods include moisture-proof aluminum foil bags with desiccants, reels, bulk, and tape packing. Storage conditions specify temperature and humidity limits before and after opening packaging, with baking procedures if moisture limits are exceeded. Lead forming and soldering guidelines prevent mechanical stress and ensure reliability.

11. Specialty and Automotive LED Products

Specialty LEDs cover full color, high power, portable, signage, and special effects lighting with detailed chromaticity, luminous intensity, voltage, and mounting data. Automotive LEDs emphasize sulfur resistance, high reliability, and are optimized for LCD backlighting and interior/exterior lighting. Typical forward currents range from 20 mA to 350 mA, with forward voltages between 2.9 V and 3.6 V. Packaging quantities range from 3,000 to 12,000 pieces per reel.

12. UV LED Specifics and Safety

UV LEDs are characterized by optical power output, emission spectra, and beam angles. Safety precautions highlight the hazardous nature of UV radiation, mandating protective eyewear and strict handling protocols. Laser safety classifications (IEC60825) are referenced. Mechanical dimensions and mounting methods are detailed for various UV LED packages.
