Technical niche and patent layout of crystal high-efficiency LED filament lamp
More and more manufacturers in the LED lighting industry have entered the niche market and special markets to get rid of the price war in the general lighting market. Not only plant lighting, medical and shipping, smart lighting and other products have come out, high-efficiency LED tubes have gradually replaced traditional low-cost LED tubes. The use of a large number of decorative lighting market, also because of the technical maturity of the LED components and market development, has produced a series of changes: due to traders, distributors and lighting designers to increase the favor of LED filament lights, so that the structure and industrial ecology The best LED filament lighting products are popular, gradually replacing the early low wattage LED bulbs, and the old LED candle lamps with large heat, becoming the star LED products with rapid visibility in recent years. The demand for decorative lamps broke out, driving the LED filament lamp market to take off. LED candle lights and decorative lighting used in churches, commercial spaces, restaurants, hotels, and LED lighting can be seen. The speed of LED filament lamp expansion can be seen. They are more popular among designers, consumers and clients than traditional LED bulbs or LED candle lamps of the previous generation in terms of styling, brightness uniformity, space aesthetics and retro feeling. With the fall in the price of LED chips, the market potential of LED filament lamps can be foreseen in 2015. In 2016, the purchase of LED filament lamps in various markets can be described by a large burst. As long as the LED filament lamps with a luminous flux below 450lm, there is a chance to obtain a large number of purchases from the channel manufacturers, and can also be used to replace them with decorative lamps. The balance between patents and technology Epistar is the manufacturer of LED filament lamps earlier. As early as 2007, Jingdian launched its layout through related patents. LEDinside interviewed Director Lu Hongyuan and Director Lin Yanyuan of the Crystal Power Marketing Center. From their experience in cooperation with the industry and their efforts in LED filament lamps, learn more about the industrial trends and intellectual property rights of filament lamps. Director Lin Yiyuan said that Jingdian's LED filament lamp has a complete patent on the relevant chip and a part of the structure, and through the authorization of patents to the middle and downstream manufacturers in different markets, to increase the competitiveness of customers using crystalline LED chips. (Left: Marketing Director Lu Hongyuan; Right: Marketing Center Director Lin Yiyuan) Crystal Power's partners in the Chinese market are mostly LED packaging manufacturers, and there are also local manufacturers of LED bulbs. These manufacturers started out as incandescent lamps in the early days and have rich experience in bulb production. This manufacturer with certain traditional technology production capacity plays an important role in the current LED filament lamp market, which is mainly based on glass bulbs. Cooperation with Jingdian in the industrial division of labor has further expanded business opportunities. Technically, Director Lin said that in the case of a general LED filament, if a small LED chip driven by a current of 30 mA is driven at 12 mA, the heat generated is low, the life of the product is increased, and the pitch is also changed. small. There are about 25 such small chips on one LED filament, and one LED filament lamp for decoration has hundreds of LED chips. To make LED filament lamps that can replace or approach general lighting, the LED chips used will consume more, which is currently seen in the LED industry. The European and American markets, where LED filament lamps are popular, and the mature markets that focus on price and quality, all attach great importance to patent intellectual property rights. Crystallization is therefore able to give full play to its patent value-added advantages and provide patented LED filament chips for lighting cooperation. partner. When these chips are applied to LED filament lamps, the quality and appearance are more prominent, which is expected to enhance the recognition of products by traders and buyers in the international market. Director Lu Hongyuan pointed out that Jingdian is actively assisting customers in the European and American markets, not only from the technical side, but also invested a lot of efforts in product marketing to improve the market visibility of patented LED filament lamps. In the past two years, Jingdian and its partners have received many orders for replacement of LED filament lamps from decorative lamps, candle lamps, crystal lamps and art lamps in North America. Customers are more comfortable with patent-protected products. Don't worry. Products are affected by patent issues and shipments. The next battlefield for LED filament lamps - commercial space and general lighting The LED filaments in the early LED filament lamps must be manually spot welded, which is quite expensive and not very acceptable in the market. In the existing LED filament lamp production process, the labor demand is more, the cost is still higher than the general LED bulb lamp; if the degree of automation can be improved, the cost has a chance to decrease. When the industry develops and introduces automatic spot welding equipment, the overall cost is expected to be further reduced. The observation of crystal electricity is based on the premise that the cost can be accepted and finally balanced with the terminal price. When LED lighting manufacturers put more LED filaments in the higher wattage LED filament lamp, no matter the use of frosted glass The appearance, or changing the internal heat dissipation mechanism, can be done better than the current decorative LED filament lamp. Jingdian expects that when the cost of LED filament lamps continues to decrease, the market size is expected to further expand. At the same time, the LED filament lamp industry, including Jingdian and its partners, is actively developing more suitable technologies to enable LED filament lamps with hundreds of tiny LED chips to have more different space and improve product durability and life. This is a good news for the purchase and application side. In fact, local markets also prefer round bulbs and retro-shaped bulbs. This allows LED manufacturers to pay more attention to the multi-presentation of internal LED filaments when designing LED filament lamps, such as vertical or horizontal mode, or designed as a love type. English letters, even mosquito-repellent incense 360 ​​degree illumination angle type. Inflatable heat can be put into the inert gas, so that the LED filament lamp presents different lighting effects, winning the favor of the commercial market and the special market. Light efficiency and energy regulations drive LED filament lamp product upgrades North American market specifications, such as California's CEC certification, help LED filament lamp products enter public standards, public lighting and other fields. Since North American customers need to develop products that comply with CEC specifications, CRI needs to be more than 90, and R1 to R8 should also meet 72. All filament manufacturers drive LEDs with lower current when considering the heat dissipation and life of the filament. chip. Crystal Electric is good at such low current density products, which can make LED filament lamps have more stable quality and service life. Jingdian believes that in the future, LED filament products will have the opportunity to jump off the existing pattern, increase the wattage and expand the applicable range. It will expand from the original decorative lighting market to general lighting and main lighting. LED filament lamps manufacturers aim to increase product luminous flux, and crystal power is no exception as a supplier of LED chips. The use of chips supplied by crystal power to make LED filament products can reach more than 140 lm per watt, which meets the requirements of energy efficiency and light efficiency in many markets. When the luminous flux of the LED filament lamp is increased, it can replace the 60-watt lighting product, as the general lighting, the main lighting, and drive the LED filament lamp product upgrade.
