In 2003, with the official establishment of Phenix Lighting, we started the R&D of the first global full-voltage emergency ballast as required by a foreign customer in the wind energy. With the continuous deepening of research and development, along with the overcoming of technical difficulties, we strongly felt in the field of emergency lighting, especially for the top customers in the North American market, only the excellent professional research and development ability and sufficient reliable product performance can win the survival in this market. The strict requirements from the market also coincide with our development concept of “making the best products”.
From then on, we officially devote ourselves to the development and manufacturing of emergency lighting products. Through 20 years of continuous exploration and attempts, up to now, we have had very complete emergency power supply product range incl. LED emergency driver and Mini emergency inverter.
In this long period of 20 years, each new series launched, hidden behind an unforgettable experience.
The development cycle of an emergency power supply is very long, not only because the electrical circuit design is complicated, also consider that it needs a long time to verify the feasibility of the scheme, reliability test of components and durability test such as high and low temperature charge-discharge cycle.
In Design Verification Process (DVP) phase, we will combine with the relevant requirements of DFMEA (Design Failure Mode and Effects Analysis), and carry out a comprehensive consideration of the various risks that may exist in the design stage. The first DVP samples need to pass hundreds of test items. Through rigorous analysis of each test result, the performance of the product is assured. If one of the technical indicators fails to meet the criteria, all test items must be restarted after debugging. Through such a rigorous system, new product’s potential failure risks are eliminated one by one.
After the completion of the first DVP samples test and approval test, DVP (Design Verification Process) Trial Production is needed. The component SMTs and plug-ins are carried out in the 100,000 level dust-free workshops. All kinds of jigs and fixtures should be in place, and the furnace temperature curve should be measured well to ensure that each piece of circuit board is heated evenly and each solder joint is firm without damaging components. After the PCBA is finished, each board shall pass the electrical parameter test, and after various indicators are achieved, the assembly and aging process shall be carried out. Before aging test, 20 times of switching on off impact tests will be carried out. And then 5 voltages of charging and discharging cycle test will be carried out for a week so as to check the tolerance of the product and components finally. After that, the DVP pilot product will undergo more high and low temperature reliability tests in the R&D laboratory, which will continue for about six months.
After the successful trial production of DVP, the first PVP (Production Verification Process) Trial Production was officially entered. In strict accordance with PFMEA (Process Failure Mode Effects Analysis) after the volume of the potential risk analysis, refer to the DVP process is exactly the same, until the completion of 5 voltage charge-discharge cycle test. It is mainly to inspect the correctness and consistency of batch incoming materials, as well as if all factors such as the human, machine, material, method and environment are correct in the production process. After a successful PVP Trial Production, the mass order production can be approved.
Each batch order is tested for 100% electrical performance before delivery and is subjected to a five-voltage aging test after assembly. Through adequate verification and testing, ensure that each product provided to customers is of the highest quality.
