LED power transformer manufacturers look forward to the amount
Switching power supplies are unmatched in terms of light efficiency, input voltage, load and efficiency, and are therefore widely used in LED lighting products. As the core component of the switching power supply, the transformer plays the role of buck-boost, rectification, frequency conversion, filtering and energy storage in the circuit. Its main performance indicators include inductance, voltage ratio, efficiency, leakage current, DC resistance, and electric strength. , insulation resistance, mechanical size, interlayer insulation, etc.
Small factory
Due to the wide variety of LED lamp beads, the serialization method is changeable, the products are not standardized, and the customer needs are diversified, which has created the diversity of LED lamps, which directly leads to the LED power supply output power not being able to be manufactured according to the standard lamps. Transformers have a history of nearly a few decades. Traditional large factories generally use machine automation. If LED transformers are produced, they will face several times of changing the line several times a day, which will undoubtedly increase production costs and greatly reduce production efficiency. Therefore, even if they receive an order for the LED transformer, they will only choose not to do it or directly post the order. The longer delivery period forces the LED power supply manufacturer to find another small factory to get the goods.
“The small factory orders are small, there are some special custom-made private model products, and they are simply doing manual work.†The reporter learned from the vice president Xie Meihua of Shenzhen Jiameirui Electronics Co., Ltd. that they currently have dozens of LED power transformer models. Kind, the number of models of the open model is not included. “Manual operation is difficult in product quality control. Most of the time is half a circle and less than half a circle. The situation of the left and right sides of the winding occurs sometimes, and these will have an impact on the accuracy of the transformer, which may result in the power output value and the lamp parameters. Matching is especially noticeable in narrow-range output load voltages,†said Wang Jilin, technical engineer at Anderson Electronic Technology Co., Ltd.
"The purchase of small-sized electronic transformers is also a helpless choice, so we have to face the risk of a 6% drop in efficiency LED power supply." Zhang Yimin, general manager of Shenzhen Tianxiaming Power Co., Ltd. said that the failure rate of the large-scale electronic transformer may be 0.3/ Oh, and the failure rate of the small factory is basically 1%.
There are also many LED power supply manufacturers such as Shenzhen Delip Optoelectronics Co., Ltd., trying to shorten the transformer manufacturing cycle and adjust a variety of product lines by establishing a professional "LED Transformer Division and Rapid Proofing Group" to ensure consistent product performance and quality. Sex. However, no matter which kind of coping method is adopted, the result is that the cost of a single transformer is high, product consistency is poor, and work efficiency is low.
