3 Steps for AKE LED Manufacturing Quality Control
Our factory conducts targeted and comprehensive control from raw materials, packaging, and every production link to finished products to ensure the quality of our products.
Premium Raw Materials
AKE LED factory purchased every material for headlight production, all tested by professionals.
Inspect incoming raw materials such as LED chips, aluminum substrates, drivers, fans, and cables to ensure they are defect-free and meet specifications.
This step not only ensures that all raw materials meet the highest quality standards, but also ensures that AKE delivers the high-performance, durable products it promises to its customers.
In-Process Quality Control
This step primarily involves inspecting the LED headlight manufacturing process before the product is fully manufactured.
We randomly sample our semi-finished products to ensure they meet quality standards, checking for issues such as fan cooling performance.
Our goal is to achieve zero-defect products and maintain a 99.9% product qualification rate.
Final Quality Control
We focus on comprehensive quality control testing of the LED headlight bulb before packaging and shipping.
Ensure that the product meets industry regulatory standards.
Other Types of LED Headlight Bulb Testing Methods
Our products are not only tested during the development and production stages, but also tested before shipment to ensure consistency and stability.
Apart from the three-step testing, we also have other types of tests：
- Optics Testing
Tests the brightness and beam pattern of LED headlight bulbs to ensure the product meets automotive road safety standards.
Purpose: Primarily to ensure that LED headlight bulbs do not produce glare, affecting the safety of other drivers.
- Integrating Sphere Testing
Accurately measures the total luminous flux (lm), color temperature (K), and luminous efficacy (lm/W) of LED headlight bulbs.
Purpose: Ensures consistent light output for every headlight bulb, ensuring compliance with industry performance and quality standards.
- Aging Testing
Every headlight bulb undergoes this test before being packaged and shipped to the customer. Simulates real-world usage over 3-5 years.
Purpose: Identifies lumen degradation, changes in color temperature and thermal stability over time, and detects early failures in the LED, driver, and fan. Ensures our headlights have the expected lifespan.
- Extreme Testing
Places the headlight bulbs under worst-case conditions to test the product’s durability (e.g., extreme temperatures, vibration, thermal shock, water, etc.).
Purpose: To ensure the durability and safety of each LED vehicle light bulb under various harsh driving conditions.
