![]() ![]() Testing the product is a good opportunity for manufacturers, paving the way for improving parameters such as brightness, efficiency, and functionality. Testing the LED products allow us to identify the problems. The operator assembles the product by following the assembly instructions to simulate the actual process the consumer will experience. Mounting control helps to verify whether customers can assemble the product easily, install and use it quickly. Some products delivered the consumers demounted and those parts must be assembled by consumers. Not all lighting products offered for sale are ready for use. IP65 is necessary for outdoor lighting which express resistance to water. The degree shown as IPXX, the first digit shows resistance to solids and the second digit shows resistance to liquids. The IP (Ingress Protection) degree determined after the leak test. For the product to be electrically safe and long-lasting, leak proof must be tested. The leak test determines whether the housing of lighting products can protect electrical parts against water and dust. While there are different standards for EMC measurements, the requirements are largely similar. This test should be performed in an isolated room or ideally in a special EMC lighting test room. Electromagnetic parasite may damage the other electronic devices and cause faults. The report includes power consumption, power factor, light output, color temperature, color rendering index.Įlectromagnetic compliance (EMC) test serves to verify that the lighting product does not emit excessive electromagnetic interference during use. Operator placed the lighting product to integrated sphere and observed the results by computer interface. A spectroradiometer and calculation software should be used with the integrated sphere. After the test, damages checked on the product.īrightness, color, and efficiency values of light source measured with the help of an integrated sphere. Drop height can be changed according to the weight of the product and standard to be applied. Lighting product dropped from 1 meter height. These functions are checked if it contains collapsible and moving parts.ĭrop test applied to mobile lamps such as flashlight and table lamp. Operators push the button or the key couple of times. Fatigue test helps to evaluate the durability of long-term use of functional parts. Key, button, and similar moving parts of lighting products use thousand of times during the life of the product. It checks whether there is any malfunction during this time. Operator leaves the light on at maximum setting for at least four hours. Durability test also known as operating test, evaluates the performance of lighting products in time. For this reason, it must be resistant to long-term use. All the functional problems that observed, any deviation from the user manual and specification should be reported.ĭuring the functional test, operator tested all functions of the product in a short time period. Controls the lighting status and confirms that dimming properly. This test does not require a special equipment. The testing process of LED lighting devices consists of several steps, each with a high degree of importance.įunction test helps verify that the lighting product is working properly. Manufacturers can identify the faults by testing correctly before the shipment. LED lighting devices tend to fail prematurely, similar to other consumer electronics products. This is because manufacturers test LED products incompletely, incorrectly, or not at all before shipment. In many applications fault ratio can be up to 10%. The standard fault ratio in LED lighting sector is accepted as 3%. Therefore, customers buy high quality products. Bulb and light fixture with LED light sources tested before entering the market. LED lights should meet certain criteria to operate safely and long. LEDs are long live and efficient light sources. More consumers meet the LED lighting day by day. ![]()
