What can the LEDs remove without packaging, heat dissipation, and no power?
The just-concluded two sessions not only signaled the steady development of the real estate market, but some cities followed closely with a series of new policies to save the property market. The weak Chinese property market will usher in new hopes, and those who just need to buy homes will also promote new developments in the home decoration industry including LED lighting. However, with the arrival of the new normal of China's economy, in the context of the slowdown in economic growth, everyone is watching the "money" more and more tight.
In order to open the market, further lowering prices will become the most effective means. The LED lighting industry is no exception. In 2015, the price wars of commonly used LED products such as bulbs and lamps will become more intense, especially for the civilian market, which is in urgent need of quick opening. Under the premise of ensuring product quality, how to minimize production costs has become the key to the success of various companies in the price war. From the earliest proposed de-energization to no package, no heat dissipation, in order to save money, LED lamps can also save the å•¥?
"Three no" products have been basically formed
The so-called "three no" LED products are no package, no heat, no power, just as easy as incandescent lamps! The technical solution headed by “no package, no heat dissipation, no power supply†will become the “troika†that will lead the industry's future development trend, and will become the focus of future competition for chip packaging and lighting application companies.
Of course, before the LED chip has undergone revolutionary changes, the "three no" products do not really remove the core components of these LEDs, but achieve a cost-saving goal with a more optimized alternative.
There is no package, that is, chip-level flip-chip package. In this way, the traditional packaged gold wire, bracket, solid crystal glue, etc. are removed. If the application is widely applied, the cost performance and cost advantages are more obvious; no power supply is the linear drive IC solution. It is also called power supply. The power supply and the light source are combined into a photoelectric engine, so there is no need for electrolytic capacitors and transformers; no heat dissipation, when the electro-optical conversion of the LED chip reaches 100%, and the power supply does not need heat dissipation, the heat dissipation kit can be taken. Lost, the current can only be reduced as much as possible and cannot be completely removed.
In the LED lighting industry, especially the integration trend of indoor and small power indoor lighting fixtures is becoming more and more obvious. All of these "none" are fundamentally driven by market demand, and companies are trying to minimize the cost of LED products.
What other parts can be saved?
Since the package (light source), power supply, and heat dissipation all constitute a key part of the LED, it can be greatly simplified. So under the price pressure, what other components of LED lighting can continue to be saved?
The author believes that the next one will be the lens, the secondary optical lens!
Since the light from the LED chip is scattered and glaring, it requires a light diffuser to adjust. Optical systems that change the light field distribution of LEDs, such as lenses and reflectors, are such light diffusers.
As a substitute for traditional lighting fixtures, LED has many advantages in terms of energy saving and high efficiency, but it has not been fully popularized into the hands of ordinary consumers. Among them, the price is a major cause. The improvement of the LED lighting market requires the relevant accessories to make concessions on the cost price, and the lens products bear the brunt.
At present, it is an LED filament lamp that is relatively mature in lensing applications. In the past, LED light sources had to achieve a certain degree of illuminance and illumination area, and optical devices such as lenses were required. This affects the lighting effect and reduces the energy saving effect of the LED.
However, the LED filament realizes 360° full-angle illumination, and the large-angle illumination does not require a lens to realize the stereoscopic light source, thereby avoiding the effect of the lens effect on the light effect and causing the light loss.
Of course, the lensless solution only has a good effect on a few LED lamp types, and most of them are still inseparable from the lens.
summary:
Markets, technologies and costs are mutually reinforcing and mutually influential. Advances in technology have spawned new application markets, and cost reductions have spurred the penetration of technology into emerging markets, and the rise of emerging markets has placed higher demands on technology and cost. This dependency is no exception to the LED industry.
With the development of LED technology and the intensification of market competition, the entire LED industry will tend to be centralized, the industry chain will be gradually shortened, and the trend of product integration will be clear. The current "three no" products and de-lensing in the industry are exactly the embodiment. In the future, there will be more "simplified" LEDs waiting to be "discovered."
Magnetic USB Cable refers to the magnet male and female to suction mode to connect the charging effect of the charging cable. Rely on the magnet magnetic attraction, traditional cable connector is separated from the cable body, both through magnetic in automatic adsorption within a certain distance, so called magnetic suction cable magnetic suction cable, magnetic suction cable, magnetic suction charging cable, etc.so that we can realize single hand plug cable, and in the process of actual use, the magnetic suction charging cable is safer than ordinary USB Cable.
Interface widely applicable to mainstream models.Thin small size for wide, differs from the traditional life of the common data interface,a new type of magnetic suction cable charging interface on the size of the thin body, even mobile phones with a set of use, magnetic suction cable also apply to the charging 90% of cell phone sets, don't need to pick a set can be used directly, so it is suitable for use in the increasingly miniaturization of electronic equipment, Can withstand more than 50,000 times of repeated insertion and removal. Fast transmission speed, perfectly compatible with mobile phone data transmission.
It is easy to use,can be single-hand operation,regardless of positive and negative, random insertion, the error rate is zero, even if the 3-year-old children can not be inserted wrong, very suitable for driving, sleeping and other life scenarios. The appearance of magnetic charging cable has impacted the market of Usb C Cable, because magnetic charging cable is much better than ordinary data cable, bringing too much convenience to life. The feeling of user experience has also risen, and more people begin to enjoy the sense of convenience brought by magnetic charging cable to life.
