The market penetration of LED lighting products is increasing year by year.

As the market penetration of LED lighting products has increased year by year, various lighting manufacturers have also focused their new product research and development on LED lighting products. As a new energy-saving light source technology, LED has driven the development of various technologies related to its surrounding areas. At the same time, it has gradually produced various unexpected problems in its development. New market participants have redefine the market by their original advantages. Therefore, when doing LED lighting products, it is necessary to grasp the product trends of LED lamps, understand and select new technologies, solve problems, and quickly adapt to the market. First, the trend of indoor and outdoor products LED lamps can be divided into indoor lamps and outdoor lamps according to the actual application. LED technology is the first to be popular in outdoor lighting. Because of its low energy consumption, it is regarded as an ideal alternative to traditional street lamps with huge energy consumption. Together with its rich colors, it is widely used in landscape lighting. With the continuous improvement of LED light efficiency, the maturity of heat dissipation technology, and the advancement of drive technology, it has only begun to exert force on indoor lamps in the last two years. 1. Outdoor products For LED outdoor products, the domestic market generally has street lamps and linear lamps. Among them, LED street light fixtures are the most technically demanding products. The batwing's light distribution, lightning protection, heat dissipation of high-power products, drive power, waterproof and dustproof, high and low temperature application environment, and the lighting method of primary and secondary roads all determine the quality of the product. The general production method of domestic manufacturers is to arrange high-power and high-efficiency LEDs with LED-driven power supplies. Most of the early products advertised how high the light efficiency and how long the LED life. But in fact, the life of the LED does not represent the life of the luminaire. High light efficiency does not mean energy saving. In practical applications, we often encounter lighting for a long time, and the lighting effect of LED street lamps is downshifted or even extinguished. Since the light distribution of LED lamps directly determines the lighting in practical applications, we should use the value of W/km to measure the energy saving level of the product. Due to the high brightness of the LED, people are easily interfered with by the glare of the streetlight during the driving process, which should be avoided in the actual design. Early choice of sodium lamp as an ideal street light source, one of the considerations is that the yellow light of the yellow light is sensitive to the human eye and has strong fogging ability. But now the color temperature of LED products can be selected from low to high various specifications, so that it can be combined with the light and dark visual environment of the human eye to more correctly select the appropriate color temperature. In addition, it ensures the light pollution caused by no-on-light, and the function of intelligent lighting control can reduce the consumption when the traffic is idle in the middle of the night, which can further achieve the effect of energy saving and emission reduction. Linear lamps can be roughly divided into landscape lighting and application lighting. Landscape lighting emphasizes color and can choose low-power LEDs. Applied lighting requires high-power LEDs. The effect of wall-washing in applied lighting is the most common. The important factors to consider when washing the wall washer are the distance of wall washing, the shortest distance to install the wall, the uniformity of wall washing, and the dark area of ​​the wall. Because LEDs are more glaring, owners often require an anti-glare cover for such luminaires, but this will re-affect the light distribution, which is a new challenge for such luminaires. The main function of LED linear lights is dimming to produce different color variations, creating different ambience scenes. The most common dimming color is RGB dimming, and now there are dimming trends such as RGBW, WNC, and even special colors. From the perspective of the dimming protocol, the domestic is generally based on the DMX method. The most important thing about the dimming system should be the reliability and stability of the system and the maintainability of the DMX controller. It is also best to have RDM and automatic addressing to quickly and accurately locate the fixture. Since the LED linear lamp is most closely integrated with the building structure, on-site construction and installation is the biggest challenge, and it must cooperate with the electrical structure and the glass curtain wall. The compact size of the installation and the compactness of the structure are the biggest challenges of the design. In the electrical connection, the commonly used method in China is the connection method of the hand. There should be mounting fittings in the small groove that are not limited by size. From the perspective of appearance, the designer does not want to see the PCB board and the components on the inside of the lamp, and sometimes does not even want to see the graininess of the LED, which brings great challenges to the selection of the translucent cover. 2. Indoor products Indoor products are closer to the lives of ordinary people, and the market potential is huge. The main sales in the domestic market are LED downlights, spotlights and string lights. Early downlights and spotlights basically used single-particle LEDs to design different circuit boards to accommodate different powers and calibers. There are three main problems in this kind of product: First, due to the lack of mastery of various LED technologies, the product has a high failure rate. Once it fails, it needs to replace the entire product, instead of replacing the light source like a traditional product. The maintenance cost is very high. Second, the light emitted by the LED is not a uniform circular spot required by the designer, but a superposition of several spots. Third, the product of different LED particle combinations and caliber needs to be restructured, optically and thermally designed. As a result, design costs, mold costs, storage costs, and manufacturing costs increase accordingly. In order to solve the above problems, the current LED products also have some trends. For example, for the traditional QRCBC and QR111 halogen lamps, the same size LED light source can be used, and the original transformer and the lamp body can be used, and the light source can be replaced like a conventional lamp. In addition, there is a trend to use COB packages and ZHAGA-compliant light engines to standardize LED light sources, increase luminous flux while reducing dimensions, and reduce design and manufacturing costs. For spotlights, the ultra-narrow beam angle is one of the advantages of luminaire manufacturers in design and manufacturing. Dimming is also the development trend of lighting products. The dimming method of domestic indoor products is mainly 0~10V, and there are still relatively few DALI dimming methods applied in the international market. Because it is realized that LED dimming may cause color drift, the dimming requirement is no longer a simple voltage regulation current, but mainly PWM. However, this will also bring problems such as EMC to be further resolved. In the choice of color temperature, the domestic trend is 2700K and lower color temperature to bring warm and comfortable feeling. In addition, for indoor products, special attention should be paid to photobiosafety, and different filters are designed to achieve different light distribution effects. Light string products were mainly based on soft lights. One trend currently presented is to place it in an aluminum recess to achieve the function of merging with the structure. It is often equipped with a light mixing board to soften the light and grain. Since such strips are designed to be easily cut according to different lengths, the series in series is actually connected in parallel, and the current limit is limited by the chip resistors, and the length of the actual string can be extended. Another trend is that the color of the flexible circuit board is mainly yellow to better mix the color temperature and light. There is also a type of flat panel light, but the current market is more concerned about its light uniformity, generally used for decorative lighting. Second, grasp the trend of LED lighting design LED products are actually light products, light systems. This has three meanings: First, the light emitted by the product must meet the requirements of the owner, designer and construction, both qualitatively and quantitatively. In reality, there are often sales people who use the power as a basis for measuring the amount of light when communicating with the designer. They think that it is a serious misunderstanding to increase the amount of light. Second, as a best-selling product, it should be from the appearance. Quality and performance meet the requirements of owners and designers; Third, from a system perspective, enterprises should be able to systematically support users in terms of applications, products, construction, dimming and services, giving users professional, full range of application products. The whole package. The emergence of LED technology has greatly enriched the lighting products. The lamps are no longer a light source and can be used as a light source. Smaller, thinner and more functional products are changing in foreign markets. As a product that requires a variety of knowledge, LED design is the soul of a product and enterprise. Therefore, it is necessary to grasp the design trend of products rather than relying on low-cost marketing and market strategies regardless of quality.
