  • Automated SMT lines for PCB assembly
  • Conformal coating and encapsulation
  • Support shop with CNC machining, cutting, and press

The STM machines can greatly eliminates the possibility of variations common to manual assembly. The precise and high-precision automatic led pick and place machine place multiple components on the board at once, dramatically increasing productivity while reducing labor costs.

By automating the assembly process, SMT technology reduces errors and production costs, ultimately leading to more durable and cost-effective LED headlight bulbs.

YAMAHA YS12 is a high-speed and high-precision pick and place machine, which can mount from 0201 to 32mm components.also can mount 1200MM LED PCB products.

Using a YAMAHA Pick and Place Machine for manufacturing LED headlight bulbs ensures precise component placement, enhancing overall product quality and reliability. The machine’s advanced technology increases production speed and efficiency, reducing assembly time and costs. Its accuracy minimizes defects, leading to higher performance and longer-lasting LED headlight bulbs components. This automation ensures consistency and optimizes manufacturing processes.

Automated soldering works by using machines and robots to heat and apply the solder material to the metal pieces. Automated soldering offers numerous advantages over manual soldering, including increased speed, consistency, and productivity. It minimizes human error by precisely handling small or intricate components and ensures even solder application.

In short, using automated soldering machines for manufacturing LED headlight bulbs enhances efficiency and consistency. These machines can quickly solder numerous components, boosting productivity.

Using an automated glue filling machine for manufacturing LED headlight bulbs offers several advantages. Firstly, it enhances efficiency by automating the precise dispensing of glue, reducing production time and costs. Secondly, it ensures consistency in glue application, which is critical for securing delicate components in place. Thirdly, automated machines minimize wastage and errors, improving overall product quality and reliability. Finally, they allow for customization, accommodating different bulb designs and production requirements seamlessly.

Quality is one of the most important factors for producing first-class LED headlight bulbs. NAOEVO focuses on quality control at every step to ensure the highest standards of performance and reliability in their LED headlight bulbs. By meticulously overseeing each stage of production, from material selection to final testing, we can identify and address potential issues early, preventing defects and ensuring consistency.

Here are the 3 main stages of quality control in the manufacturing LED headlight bulbs.

  • Incoming Quality Control

In incoming quality control, all materials used in manufacturing are thoroughly tested to ensure top-quality standards. Each material for automotive LED headlight bulbs has specific quality requirements. This initial step is crucial in delivering the high-quality products that NAOEVO promises to clients.

  •  In-Process Quality Control

The second quality assurance test for LED car headlights involves in-process quality control. During this test, we examine the manufacturing process before it is finished and the automotive vehicle prototype is prepared for final quality control testing. This step is crucial for manufacturers because it provides assurance regarding the quality of materials used in the process and ensures that the final product meets the criteria for ‘high-quality’.

  •  Final Quality Control

The final step in testing the quality of LED automotive headlight bulbs involves comprehensive quality control testing. During this process, we thoroughly inspect the manufactured product before it is ready for sale and storage. These three tests are essential for maintaining the high quality of our products. After undergoing this extensive process, we confidently assure our global clients of the exceptional quality they can expect from NAOEVO.

Apart from the three-step testing, there are other types of tests that are done to ensure the quality of LED headlight bulbs.

  •  Optics Testing

An optics test of an LED headlight bulb evaluates the light distribution, intensity, and beam pattern to ensure it meets safety standards and provides optimal visibility. This test is crucial for ensuring the LED headlight bulb illuminates the road effectively without blinding other drivers, thereby enhancing both driver safety and overall road safety.

  • Integrating Sphere Testing

Integrating Sphere Testing measures the total luminous flux (total light output) of an LED headlight bulb. It involves placing the bulb inside a spherical device coated with a diffuse reflective material, which captures and evenly distributes light. This test is essential for ensuring accurate, consistent light output, verifying energy efficiency, and ensuring the bulb meets industry standards for performance and quality.

  • Aging Testing

Aging testing of an LED headlight bulb involves operating the bulb continuously for an extended period to simulate long-term use. This process helps identify potential issues like lumen depreciation, color temperature, and thermal stability over time. Aging testing is crucial to ensure the bulb’s reliability, durability, and performance, guaranteeing it will function effectively throughout its expected lifespan.

  • Extreme Testing

Extreme testing of an LED headlight bulb involves subjecting the bulb to harsh environmental conditions such as extreme temperatures, humidity, vibrations, and shock. This testing simulates real-world scenarios and ensures the bulb can withstand adverse conditions without failing. Undergoing extreme tests is essential to guarantee the durability, reliability, and safety of the LED headlight bulb in various driving environments and conditions.
