New Vision In-House LED Light Testing Methods

After the preparation of LED Lights, the company tests those making selling in the market. Mainly services of experts and engineers are availed for the said purpose.

There are different specifications of equipment available in stock. These vary in brightness, color, or temperature.

There are standards set by New Vision for ensuring the functioning of products. It means defining criteria and taking all steps to ensure standards.

Products from NV also have to go through various tests. These tests mean quality product guarantees.

When all products go through NV tests, it ensures their good quality. It means the product meets tolerance and precision and other certain set specifications.

There are two other tests as well that are performed by the technician.

  • Durability tests
  • Built-in tests

These tests can be kept for 2 weeks till some months time.

Integration Sphere

The integration sphere is a device for measuring light. It comes with an inbuilt white reflective coating. The coating ensures an even distribution of light to the interior of the sphere.

A spectrometer is used for collecting data from sensors within the sphere. The data is then giving way to computer programming. It is possible with the help of peak wavelength, lumen, CRI & CCT.

There are four spheres available in the lab. All differ in their ability to measure small and large object sizes.

Handheld spectrometers are also used for the integration sphere. Mainly small LEDs and smaller components make use of handheld spectrometers.

Environmental Chamber

The environmental chamber is a state-of-art facility. It uses a closure of 39 cubic feet. Humidity and temperature are maintained in both industrial and commercial LED.

Data collection for both electrical and photometric is possible under specified environmental conditions.

In this case, the device to be tested face the conditions of the environment. The range of humidity is from 10 to 95%. The temperature varies from 35 degrees to 200 degrees.

Vibration Test

The vibration tests are used to analyze mechanical endurance and strength. The range of the frequency is from 10 to 1000 hertz.

For the vibration test, the temperature range from minus 40 to plus 80 degrees.

The aging of the plastic is also checked through this process. Mainly the working of the light is checked for 24 hours.

Immersion and Pressure Tightness Test

The immersion and pressure tightness test is done as per the requirements. It is mainly done for all lighting functions. In a water depth of 1 meter, the pipe can be immersed.

For yet another test, this immersion can be as deep as 6 meters. Apart from this 1.6 bar overpressure is also performed.

The NV standards are set intact for performing all tests. It requires fulfilling all legal requirements, i.e., IP 67 and NV Standards.

In case of the poor condition of the road, the test helps a lot. It considers the product behaviors.

That includes gravel, dirt road, gravel track, fields, stones, and potholes. Rally profiles are also performed under special circumstances. These special profiles include auxiliary driving lights.

Immersion and Pressure Tightness Test

Heat, Moisture and Cold Test

During the temperature cycle tests, New Vision products contact in direct contact with heat.

The temperature in this case range from minus 40 to plus 100 celsius. In this case, the climactic volume remains between 600 to 1000 liters.

Also defogging and condensation tests are also performed under these conditions. These include humidity to 80 percent and condensation to 95 percent.

Within the stock chambers, the temperature changes rapidly. This variation in temperature from -40 to +100 happens in just 6 seconds.

These kinds of tests are stressful for any lights and other electronic components. Both cold and heat tests remain intact for around 48 hours.

Dust Test

To ensure the tightness of the dust, this test is performed. Mainly the product used as dust medium, in this case, is unfired portland cement.

For operational purposes, the test is performed as an option. The test is performed in case of overpressure and underpressure products. The photometric value is also considered for these tests.

These values are recorded before and after the test. The acceptable range is from IP 5K. NV ensures the trapping of dust in the system could be avoided at all costs.

High-pressure Cleaner Test

This test product is tested with respect to water pressure and water temperature. The testing temperature is +85 degrees and the pressure is 120 bar.

With the help of the test, cleaning during carwash is ensured. Also cleaning pressure of IPXK95 is maintained.

High-pressure Cleaner Test

Splash Water Test

NV ensures perfection in all product functioning. It also keeps in mind customer satisfaction towards accessories and product categories.

NV standards mean precision, tolerance, and standards meeting for every product. The cabin has facilities to deal with rain, splash, waterfall, and water mist.

The water splash and intermittent tests are done to ensure product tightness. The jet water pressure is kept at 10 bar and the splash water pressure at 5 bar.

FLIR Camera

The email emitting from the LED products is tested through FLIR Camera. A thermal image is created by the camera.

It highlights the area from where the light is coming. The camera also tells how hot the object might be.

Also, the internal temperatures of the products are also measured with the help of the camera.

Durability Tests

For analyzing the working of the products, different tests are performed. LED light is tested in the environment for which it has been created.

For example, waterproof lights are to be immersed in water. Also, weather-resistant lights are placed outside.

It all depends on how and in what capacity the lights are to be used. These are checked and tested accordingly in the same environment.
