So is the era of intelligent control already coming? How should LED power companies take the road of intelligence? Focusing on intelligent dimming, Dongguan Linguan Semiconductor Lighting Co., Ltd. (hereinafter referred to as “Leading Crownâ€) achieved revenue of RMB 10 million in the first quarter of this year, an increase of 30% year-on-year. To this end, the new century LED network reporter invited the general manager of the crown Liao Yuzhu to share the experience of LED power companies to develop smart lighting market.
Technical strength: professional team and leading equipment based on the reporter, according to the reporter, the leader from the traditional consumer electronics switching power supply transformation focused on the production of LED power supply, the company's technology and management team have more than 10 years of switching power supply background, For the enterprise itself, the LED power supply is only a new positioning in the market. The current products of the company are positioned in the mid-to-high-end market, and the focus is on the field of dimming power. At present, it has obtained dozens of independent intellectual property rights including thyristor intelligent control dimming technology, GU10 small power supply through global certification technology, MR16 compatible electronic transformer technology, compatible magnetic ballasts and electronic ballasts. National Invention Patent.
Dimming power is a major feature of the leading power supply products, but also the advantage of the enterprise. Liao Yuzhu said that the current dimming power supply has accounted for 80% of the company's total sales.
At present, the LED dimming power supply on the market is mainly a thyristor dimming power supply. Due to the lack of a perfect product solution, some dimming power products have poor dimming effect, poor compatibility, low efficiency, and fail to meet safety regulations and EMC requirements. The problem. So how does the leader guarantee the quality of the product technically? The use of the most advanced research and development and production equipment is the prerequisite for ensuring product quality.
According to Liao Yuzhu, the LED power supply R&D equipment of the crown is mostly made of advanced equipment from the United States and Germany. For example, the test center is equipped with an EMI shielding room, an EMI conduction tester, a harmonic current tester, an electrostatic discharge generator, a pulse group generator, Lightning surge generators, cycle drop simulators, infrared imagers and other leading equipment.
Product quality: Strict quality control is guaranteed. In addition to the advanced R&D and production equipment as the premise of product technical guarantee, the quality control in the production process also determines the quality of the product. Each company has its own different product management and control procedures in the production process. Liao Yuzhu also shared the quality control process of the leading products through an example of a product project:
All products must be produced in three steps through mass production. Liao Yuzhu said:
Project phase: The company collects a large amount of market information feedback and research; selects the most cost-effective or personalized program, and then conducts research and development.
Product Verification Phase: Testing with advanced instruments to verify the temperature of the LED power supply is very important, so we will set the test environment temperature of the power supply to -40 ° C 80 ° C, the products that can pass this temperature range can pass the engineering verification data. Scoring: Liao Yuzhu said: We will conduct a 100PCS small batch of data analysis to observe the consistency of the electrical parameters of the product. Finally, we will discuss the data together and discuss the products that can be mass-produced.
In the production stage of the product, the management of the raw materials in the raw material feeding, production process, shipment inspection, storage and warehousing will also take strict measures to ensure that each product can achieve the desired design effect. How is the control of the product a harsh one? Liao Yuzhu said: The key to LED power quality is aging. We have five sets of intelligent aging control systems, which can set the ambient temperature. The batch aging environment temperature setting is 65 °C, and the product must undergo 4 hours of cycle aging. Shipped. We need to pass nearly 3.5 tests after the initial test of electrical equipment, 4 hours of high temperature aging test, electrical parameter retest, quality control test, etc. The products that pass the test are the products we think can be shipped.
Quality management is the most important link, and it is also the most indispensable part of our business. This is the fundamental point of production and management of enterprises. Liao Yuzhu said.
Liao Yuzhu's value to the product is so general: I hope that the LED power supply we provide can maximize the value of the customer's LED products, so that the electrical parameters of the LED products can stand out in the same type of products.
Dialogue market: Using certified products as a chip, the reporter learned that the threshold for LED external power supply to pass export certification is not high, but because foreign finished lighting companies have special requirements for LED power products, such as dimming, power supply volume and other strict requirements, This makes it difficult for LED power companies to export their products. The LED export business of the crown crown accounts for 80% of the total business volume of the company. When it comes to the problems encountered in the export of the LED dimming power supply, Liao Yuzhu appears to be relatively easy: the certification requirement for the thyristor dimming power supply is to pass the EMI Test, dimming effect and EMI test are just conflicting. The dimming effect and electromagnetic interference are contradictory. To deal with the contradiction between the two, the company's dimming power products can technically solve this conflict. To solve a series of problems, the products can meet the core requirements of the customers. This requires the company to have strong technical strength as a guarantee. We have already obtained good solutions through technical research and development.
At present, LED dimming power supply independently researched and produced by Leading Semiconductor Lighting has obtained certifications including TUV, SAA, PSE and CB. According to Liao Yuzhu, the first quarter of the company's operating income was about 9 million yuan, an increase of 35 over the same period last year. The main reason for this growth is that the LED dimming power supply that led the second half of last year won SA, CB, TUV. The certification, the performance of certified dimming power supply in the first quarter of this year has experienced explosive growth. In the second quarter of 2014, the products of the Crown are intended to apply for UL and CQC certification. Power customers with UL, TUV, PSE, SAA, CB and other certifications have high recognition and quality.
Based on the industry: Clear positioning, clear target, attitude, current LED is still in the replacement stage of traditional light source, due to the common habits of ordinary people, compared with the hot lighting of foreign markets, I accept the wireless control technology of LED lamps in the national market. The degree is lower. At present, the domestic market has high demand for LED dimming, mainly in engineering cases, such as the hotel's dimming color temperature requirements. Liao Yuzhu said: Compared with the domestic market, the current Australian market has a high enthusiasm for LED dimming. It is derived from its traditional household lighting with dimming devices. LEDs replace traditional lighting to make this market hot. In the conversation, the New Century LED network reporter learned that in the first quarter of this year's performance, the Australian market has the largest demand for products.
So focusing on smart dimming power can stand firm in the market? It is understood that the current market layout of LED power supply manufacturers in this field is cross-expanding. Moso Power and Infinity have successively established the LED Indoor Power Division, in which Infineon will also extend its reach to the LED power driver IC. Frontier companies have crossed the layout, and the rising star has also followed suit. Liao Yuzhu introduced that the collar is focused on indoor thyristor dimming, and is also on the market for LED outdoor waterproof power supply. In Liao Yuzhu's view, nowadays, with the increasingly fierce market competition, perhaps the future market of the enterprise itself will be squeezed by the strong power supply companies, and some LED finished lighting factories will also start to develop LED drive power products. The market space of the company itself will become smaller and smaller, so the cross layout is very necessary for the enterprise. Of course, this requires the company itself to have considerable skill to achieve cross-distribution of products. This is a systematic project, not only pure technology research or development or market layout. The need for a company with diverse capabilities can be achieved.
Companies engaged in LED drive power are under great market pressure, but we may be less pressured to make market segments than companies that do mass market. In the face of market pressure, our technology-based enterprises still have to cultivate their own internal strength, relying on core technology to achieve the ultimate in the market segment. Liao Yuzhu said.
Speaking of the company's goals in the second half of the year, Liao Yuzhu said: The application for US UL certification and domestic CQC certification is one of our core tasks in the second half of the year. According to the reporter, the biggest threshold for Chinese LED companies to enter the US market is the need for UL certification. The annual cost of UL certification is high. In this regard, the industry believes that UL certification is not a threshold, but a way to promote the quality of products. In the road to new markets, the continuous supply of the company's own product quality is the company's greatest sincerity to the market and users.
