Mingfeng’s production workshops are outfitted with a number of automated equipment pieces, including CNC equipment, chip dispensing machines, SMD placement equipment, machining equipment and more. CNC equipment carries out a quick proofing. Chip dispensing machines effectively control the color temperature of the lights, and the SMD placement equipment improves the chip productivity and quality.
Mingfeng’s facilities include a lamp assembly workshop, LED panel light assembly workshop, LED flood lights assembly workshop, LED plant grow light assembly workshop and high bay LED light assembly workshop. All production line workers are talented mechanics and have extensive experience, and we are IQC and OQC certified.
100% of Mingfeng’s products must pass a 48 hour, uninterrupted lighting test, and all of our outdoor products must pass a water resistance test. We spot-check the photoelectric data of all products in strict accordance with AQL standards, and the photoelectric detection data mainly includes power (W), efficacy (lm/W), color temperature (CCT), color rendering index (CRI), voltage, and current. On new products, we will also conduct an extra destructive testing process to ensure the final quality. Detections and tests include an optical test, electric shock protection test, waterproof test, high and low temperature testing, salt spray test, drop test, wear testing, fire test, electromagnetic compatibility and electromagnetic interference test (EMC, EMI), amd low voltage command test (LVD).
An integrating sphere is used for testing the photoelectric data of the lights, which includes optical and electrical properties. The testing report of the integrating sphere will clearly display the power, voltage, current, frequency, total lumens, light efficiency, color temperature, and display color index of lights.
A darkroom is used for testing the light distribution and the light intensity of different angles ranging from 1° to 360°. The IES files produced by this darkroom are used for planting the Dialux lighting design software, which is important for light selections in the program.
Waterproof test. Our lights can be tested according to the waterproof standard from IPX4 to IP68. This test is used primarily for outdoor products.
Salt spray test is used for detecting the corrosion resistance of the lights. It is a performance testing used for testing to determine that the lights are resistant to corrosion in specific environments.
The cutting test is used for detecting whether the heat sink has internal injury or to make sure there’s no residual material and therefore to guarantee the heat radiation of lights.
High and low temperature tests are used to determine the operating temperature. The test range of the device is -50℃-+90℃.
Room without wind. There’s nearly no air flowing in this room. After the light temperature is stable, the light will not be impacted by an external environment. The lights inside the room can easily detect the light chip temperature, the power supply, and the heat sink, making it a useful tool for the research and development of product structure.
The needle flame tester is used for detecting whether the luminaire material is fireproof. It is mainly used for power cable and plastic parts.
The screen printed light guide plate of the LED panel light ensures the light illuminates evenly to prevent dark spots and areas. The screen printing LED panel light features a high quality, low cost, and excellent productivity.
The regular products have the 48-hour uninterrupted lighting test and the new products have the 72-hour lighting test. During the lighting test, the lights will also have the high and low pressure impact testing which is for imitating the working condition of our client local power grids to make sure our products are 100% suitable for the local power grid.
