Quality & certification
ISO 9001 QMS across R&D, purchasing, production and shipping. CE, RoHS and related files per model for overseas tenders and customs.
Four lines of quality defense
Inspection and quality-control responsibilities are separated across key stages of production.
Incoming IQC
LEDs, batteries, controllers, structural parts and packaging materials are checked before entering production.
In-process IPQC
Assembly, wiring, charging logic and functional checkpoints are verified during production.
Outgoing OQC
Finished products, accessories, labels, packaging and shipping marks are checked before shipment release.
After-sales tracking
Quality issues are recorded by batch and model to support root-cause analysis and corrective action.
Incoming inspection, in-process control, outgoing inspection and post-shipment issue tracking work together as one closed-loop quality process.
How the system is implemented
Documented, auditable, inspectable
Quality control is supported by documented procedures, approval records and inspection checkpoints from incoming materials through final shipment.
- Approved work instructions and inspection standards
- Incoming, in-process and outgoing quality records
- Batch-level traceability for key product versions
- Corrective actions documented when nonconformance occurs
Engineering-backed quality metrics
Engineering and quality teams review key product parameters, test methods and approval requirements before stable mass production.
- Optical and electrical performance checks
- Battery, controller and luminaire verification
- Environmental and reliability test references
- Production records retained for repeat orders
Certificates & credentials
Selected compliance and test documents support routine project review and customer verification.
Outgoing inspection record sample
OQC before shipment
Before shipment release, finished products and packing details are checked against the approved order configuration.
- Model, quantity, appearance and accessory confirmation
- Label, carton and shipping-mark inspection
- Functional and lighting-mode spot checks
- Inspection result retained with the production batch
Batch traceability
From batch number to service ticket
Production batches keep model and order information connected to quality records, helping after-sales teams trace issues more efficiently.
- Batch number linked to production records
- Product variant and configuration identification
- Inspection and shipment records retained
- After-sales cases can reference the original batch
Bid / acceptance document pack
Typical quality and technical documents that can support customer review, tenders and project acceptance.
| Document | Typical contents | Purpose |
|---|---|---|
| System document package | ISO 9001, CE, RoHS and selected test documents | Compliance review |
| Component / material confirmation | Approved BOM, model and key component references | Production consistency |
| Outgoing inspection record | OQC sample, appearance and packing verification | Shipment acceptance |
| Warranty & after-sales policy | Warranty period, claim flow and service conditions | After-sales reference |
| Product test evidence | Photometric, IP, salt-spray and related reports where applicable | Technical verification |
Optical & photometric capability
Spectral and photometric verification supports consistent lighting performance across approved product versions.
Engineering files on request
Optical performance can be supported by test records and project files for suitable solar street light models.
- IES / LDT files for lighting calculation
- Spectral and photometric test references
- DIALux simulation support for selected projects
- Approved optical data linked to product versions
8D corrective & preventive process
Major quality issues can follow a structured corrective-action process from problem definition through verification and prevention.
Nonconformance & corrective flow
Identify & quarantine
Isolate abnormal material or products and prevent unintended release.
Containment
Define immediate containment actions for the affected batch or order.
Root cause
Review process, material, method and design factors behind the issue.
Corrective action
Implement process, inspection or engineering changes as required.
Effectiveness
Verify the corrective action and standardize preventive controls.
Quality policy owners & risk shields
R&D + production · quality loop
Quality assurance is linked across engineering definition, manufacturing execution and certification records.
R&D capability
Product platform, optical configuration, BOM and verification requirements are defined before production.
Manufacturing
Standardized production instructions and batch-level process controls support repeatable execution.
Quality & certification
IQC, IPQC, OQC, test reports and compliance documents support shipment and project review.
