3030 Dome SMD LED Indicator, Single Color Surface Mount LED Diode

3030 Dome SMD LED - Hongcheng Optoelectronics LED Manufacturer

Product Overview:

The 3030 is a high-brightness top-emitting SMD LED in a 3.0×3.0mm package, featuring high brightness, good heat dissipation, low light decay and strong stability. Ideal for commercial lighting, outdoor lighting, luminaire modules and advertising backlighting; color temperature, brightness, voltage, CRI and power can be customized.

Key Advantages:

  • 3030 standard package, front emission, good compatibility
  • High brightness and high efficacy with uniform, stable emission
  • Good heat conduction and dissipation, reducing long-term light decay
  • Available in white, warm white, red, green, blue and other colors
  • Color temperature, brightness, voltage and wavelength binning available
  • Compatible with automated SMT production and reflow soldering

Applications:

  • LED bulbs, downlights, spotlights and panel lights
  • Street lights, high-bay lights and outdoor luminaires
  • Light boxes, advertising signage and backlight modules
  • Horticulture lighting, landscape lighting and special light sources
  • Automotive auxiliary lighting and electronic equipment light sources
  • LED bars, rigid strips and lighting modules

Product Features:

Chip: Grade-A chips from leading Taiwan and mainland brands with high luminous efficacy, low light decay, stable output and strong ESD resistance.

Gold wire: 99.9% pure gold wire bonding with excellent conductivity and fast heat dissipation for improved reliability.

Encapsulant: high-quality epoxy with high temperature resistance, anti-sulfurization and low light decay; resists discoloration over long-term use.

Lead frame: high thermal conductivity frame with good heat dissipation, easy tinning and oxidation resistance.

Packaging: vacuum moisture-proof tape packaging, reel shipping available, compatible with automated SMT equipment.

Frequently Asked Questions (FAQ)

1. Can I get free LED samples from Hongcheng Optoelectronics?

Yes. Dongguan Hongcheng Optoelectronics Co., Ltd. supports sample testing — you can verify electro-optical parameters, dimensions and soldering compatibility before placing bulk orders. To request samples, call +86 139 2571 4318 (WeChat same number) or email sales@led-hc.com with the model and quantity you need.

2. What is the minimum order quantity (MOQ)?

The MOQ for DIP (through-hole) LEDs is 1K (1,000 pcs); for SMD LEDs the MOQ is 3-5K, shipped in tape-and-reel packaging. The MOQ for customized models (special wavelength, brightness or voltage binning) is confirmed per custom solution. Please contact sales for an accurate quotation and MOQ for your model.

3. What are the lead times for samples and mass production?

Sample lead time is typically 3-4 working days; in-stock samples are usually shipped within 2 working days. Mass production lead time is typically 10-15 working days, confirmed according to order quantity and production schedule — please contact sales for an accurate lead time.

4. Are the products RoHS certified?

Yes. All Hongcheng LED diodes are RoHS and CE certified, made with A-grade chips, 99.9% pure gold wire bonding and high-temperature resistant encapsulant — anti-sulfuration and low light decay, meeting the environmental and reliability requirements of home appliance, automotive and industrial equipment applications.

5. Can voltage, wavelength, brightness or color be customized?

Yes. We support binning and customization of brightness, wavelength, voltage and color, and provide OEM services. Our product range covers 0201-5730 SMD LEDs, addressable RGB LEDs with built-in IC, side-emitting LEDs, and 2mm-10mm DIP LEDs, packed in vacuum moisture-proof tape and reel, suitable for automated SMT mounting and reflow soldering.

6. How do I get the product datasheet?

Every model has an official PDF datasheet (electro-optical parameters, dimensions, pad design, tape packaging and reliability test data) — 259 datasheets in total, all free to download with no login required. Browse the datasheet center (https://www.hc-led168.com/datasheets) by series, or download directly from each product page.

7. Is Hongcheng Optoelectronics a factory or a trading company?

Hongcheng Optoelectronics is a member of Guangyu Group — a professional LED diode source manufacturer based in Dongguan, Guangdong, China, with 20+ years of LED packaging experience. Factory-direct sales; over 50% of raw materials are imported from South Korea, Japan and Taiwan, China. Quality and lead time are controlled directly by the factory.
