Selected application cases from our customers (company names anonymized per confidentiality requirements). For more cases and selection support: Tel / WhatsApp +86 139 2571 4318, sales@led-hc.com.
Case 1: EV Charging Pile Manufacturer — Status Indicator LEDs
Challenge: Charging piles operate outdoors for years; the customer’s previous indicator LEDs suffered fast light decay and batch color inconsistency under heat, sunlight and temperature cycling.
Solution: Hongcheng supplied 5mm through-hole LED indicators (red/green/yellow) with high-temperature resistant encapsulation, A-grade chips and 99.99% pure gold wire bonding, shipped in matched brightness/color bins.
Result: Consistent brightness over long-term outdoor operation with no batch color difference; the customer converted to long-term volume purchasing.
Case 2: Instrument Manufacturer — Panel Status Indication
Challenge: Compact front panels required small, low-power status indicator LEDs with tight brightness consistency across multiple purchasing batches.
Solution: We recommended 0805 SMD LED indicators, shipped in graded brightness bins with full binning data and retained sample comparison for each batch.
Result: Uniform indication across finished instruments; the customer continues to specify Hongcheng LEDs in new product designs.
Case 3: Industrial Control Equipment Maker — Custom Panel Indicators
Challenge: The control panel design required through-hole LEDs with specific lead length and formed bending that standard off-the-shelf parts could not fit.
Solution: We customized lead length and lead forming per the customer’s drawings, with lens color and brightness grade adjusted to specification; samples approved before volume production.
Result: Custom parts went straight into assembly without secondary processing, reducing production time.
Case 4: Telecom Equipment Company — PCB Status Indication
Challenge: High-density PCB layouts required side-view SMD LEDs in tape-and-reel packing for automated SMT assembly.
Solution: Side view SMD LED series supplied in full reels, with assembly parameter support for the customer’s SMT line.
Result: Placement yield met targets and the customer achieved automated volume production.
