No packaging / no heat / no power three LED innovation technology is pure stealing concept
As a high-tech enterprise specializing in R&D, production, sales and after-sales of high-power LED radiators, Beijing Ruide Sang Energy Saving Technology Co., Ltd. has leading thermal conduction technology and enjoys high reputation in the industry. Recently, the author interviewed Mr. Han Junzhong, Marketing Director of Beijing Ruide Sang Energy Saving Technology Co., Ltd. on the technical status of Sanwu's products, the problems that need to be solved without heat and the prospects. In recent years, with the continuous pursuit of users for product simplification and cost-effective maximization, three innovative technologies of “no packageâ€, “no heat dissipation†and “no power supply†have been born, namely the “three no†products collectively referred to in the industry. The information about the "three no" products is different. "In today's increasingly fierce LED competition, some companies continue to throw some gimmicks to gain attention, basically to steal some concepts. For example, no packaging, not to save the entire package, just save a gold The process of wire encapsulation only turns the whole package into a chip package, which is still one of many package forms; without power supply, it basically belongs to the traditional power supply form, changed to patch type, and together with the light source, then this can Is it a powerless, just an integration, accurately said that there should be no independent power supply; as for no heat dissipation, it is nonsense, small power may not need to pay too much attention to heat dissipation, high power or super power, as long as the LED light source technology is not With revolutionary changes, heat dissipation is always an indispensable part. Now some light sources are only light or have a high temperature resistance. However, there is no heat dissipation, and only waiting for light decay or dead light." Han Junzhong In the interview with reporters, it is analyzed. Han Junzhong emphasized that "LED heat dissipation should not be limited to the heat sink. It should be a system engineering. For example, if the light source substrate is connected to the heat sink, if the heat of the light source is not well transmitted to the heat sink, the heat sink performance is excellent. There is no chance to work. Moreover, how long does the medium used for the connection last? If it is not solved well, it is a fatal short board that affects the life of the whole lamp." When talking about the problems faced by LED cooling, Han Junzhong raised a series of questions and asked: Considering the heat dissipation of the light source, is there any need to consider the power supply to dissipate heat? What is the solution? Single radiator, the heat dissipation effect is good in the short term, can you come up with the technical solution? To ensure the long-term stability of the product? How can the overall accessory solution have the least impact on heat dissipation? "First of all, we must be able to recognize these problems before we can have a good solution. Naturally, we have a corresponding solution." In Han Junzhong's view, no heat is impossible. He bluntly said, "What we can do is to work hard to make the heat-dissipating part, and strive to make it smaller, lighter in weight, better in heat dissipation and more stable in quality." At present, many viewpoints believe that the concept of no heat dissipation has been heated up by the industry, but it is still at the conceptual level. In this regard, Han Junzhong believes that this view is debatable: "It is still the same sentence, whether there is heat dissipation depends on whether the LED light source technology can undergo revolutionary changes. From the current theoretical calculations of experts in the industry, this concept does not have enough theory. Based on the time, the implementation time is difficult to predict." "There is no good reason for the concept of no heat dissipation. Of course, it depends on whether the product supplier communicates the real information to the user. The light decay value and lifetime value of the heat dissipation scheme and the light decay value and lifetime value of the no heat dissipation scheme. Comparing the influence and comparison of temperature on the color rendering index, the real information is conveyed to the user and selected by the user. At this time, based on the rational choice of the customer, we have a scientific basis to look into the future of the concept." Han Junzhong Finally added emphasis.
