What reliability testing and testing reports are required for LED lamps?

D lamps, as a new generation of light sources, are gradually replacing the market of traditional energy-saving lamps. However, the reliability testing of D lamps is very different from traditional lamps, and the testing methods of traditional lamps cannot be used. What are the relevant reliability tests that small current D lamps need to carry out?
1. Environmental reliability testing
Environmental reliability testing equipment includes hot and cold shock test chambers, constant temperature and humidity test chambers, rapid temperature change test chambers, vibration test benches, impact test benches, and salt spray test chambers , UV aging test chamber, rain test device, sand and dust test chamber and other testing equipment, building a comprehensive reliability testing platform. The platform can simulate the impact of various natural or artificial environmental conditions (such as temperature, humidity, vibration, impact, rain, dust, transportation, manual handling, etc.) on product reliability performance. Product testing items: high temperature test, low temperature test, high and low temperature impact, constant temperature and humidity test, rapid temperature change test, salt spray test, UV weather resistance test, rain test, sand and dust test, mechanical vibration test, mechanical shock test< br/> 2.

3. Working principle of sand and dust test chamber: This equipment has a vertical circulation airflow carrying dust. The dust used for testing can be recycled. The entire air duct is made of imported high-grade stainless steel plates. The air duct The bottom is connected to the cone-shaped hopper interface, and the air inlet and outlet of the fan is directly connected to the air duct. Then the diffusion port on the top of the working room is connected to the working room body at an appropriate position to form a closed vertical dust blowing circulation system so that the airflow can flow smoothly. , to disperse the dust evenly to the maximum extent and form a sand and dust test environment.
3. Working principle of vibration and impact test bench: The working principle of the electric vibration test bench is similar to that of a speaker, that is, the energized conductor moves under the action of electromagnetic force in the magnetic field. When the moving coil in the magnetic circuit of the vibrating table passes the alternating current signal, an exciting force is generated, and vibration motion is generated in the magnetic circuit, and the vibration test of the product is carried out. The working principle of the impact test bench is to fix the test piece on the table, and the table will fall freely to the base. A waveform generator is installed on the iron platform on the top of the base. During the impact, the waveform generator emits a waveform signal, and the entire impact process starts with the impact. The waveform change curve of acceleration with impact duration is reflected on the software interface.
4. UV Weather Resistance Test Chamber
The UV Weather Resistance Test Chamber, also known as the UV Aging Test Chamber, uses fluorescent UV lamps as the light source to simulate the UV radiation and condensation in natural sunlight, combined with temperature control. , moisture supply and other simulation devices are used to conduct accelerated weather resistance tests on materials to obtain the results of material weather resistance. Working principle: The UV lamp climate resistance test chamber performs the test by exposing the material to be tested in a controlled interactive circulation system of sunlight and moisture while increasing the temperature. The equipment can reproduce the conditions required outdoors for months or years. the damage caused. The damage caused mainly includes fading, discoloration, decrease in brightness, powdering, cracking, blurring, embrittlement, decrease in strength and oxidation.
5. Temperature and humidity detection test chamber series
Temperature and humidity detection equipment is a necessary testing equipment in photoelectric, metal, plastic, rubber, electronics and other industries. Hot and cold shock chambers are used to test product structures or materials. The constant temperature and humidity test chamber is used to test the heat resistance, cold resistance, dryness resistance, and moisture resistance of product structures or materials in various environments. It is used for rapid temperature change test chambers. It is used to detect the performance indicators of product structures and materials in environments with rapid changes in high and low temperatures. Product testing items: high temperature test, low temperature test, high and low temperature impact test, constant temperature and humidity test, rapid temperature change test.
7. Salt spray test chamber
The salt spray test chamber is a test equipment that artificially simulates salt spray corrosion environment. It is used to evaluate the salt spray corrosion resistance of materials, products and their protective layers, and Evaluate the workmanship quality of the protective layer. Working Principle The spray system of the salt spray test chamber is mainly composed of nozzles, salt water tanks and tower spray devices. The gas generated by the compressor enters the nozzle after being purified, preheated, and decompressed. The brine supply system supplies the brine to the nozzle suction pipe. When spraying, the compressed air rushes out of the nozzle and generates negative pressure above the water suction pipe. Under the action of negative pressure, the salt water is quickly shot towards the top cone by the nozzle and spreads to the entire work space, forming a diffuse state, simulating a salt spray environment.
