LED lighting industrial, the additional biggest problem is “hot”

Fourth, it is because the heat generated by the LED lights, so it needs for cooling. Compared with the light weight plastic, the thermal conductivity of the metal is much better, but also bulky enough.

Five, Light perception. In fact, it is not a fatal flaw of LED lighting. LED lighting industrial products under the case of the less electricity, and the reason for the issues of the heat for long time, it is because the LED lighting stimulate the visual sense.  But such light is too strong, and if with the quality of the shade or baffles, or in large part to address this glaring problems.

Six, with regard to prices, after read the first five principles, it is self-evident.

LED Flood lighting is not that energy-saving on the matter, the key is to make consumers feel affordable and reliable.

The word “hot” in LED lighting field is sensitive. A word “hot” make a number of enterprises exhausting and make many consumers are neurotic. In the area of LED lighting. LED lighting industrial brand in the Chinese market could get almost none. The reason is simple, it can not solve the “hot” issues.

China professional LED lighting companies seem to have a lot. In fact, except ChangFang light, Really bright, Qingshang lighting etc, most of the little-known small business in the name of walking a fine line. In fact, look at the entire China market, LED lighting products capacity is not large enough to hold up more than one billion people in China’s consumption. So LED lighting industrial gets hot. How long does it sustained? How to continue the fire? This is the number of LED lighting enterprises and the people involved in the LED products, we can easily see that put in the LED lighting industry, the most urgent and the biggest problem is the “hot” instead of “heat”!

We use the foreign machinery and equipment to produce chips, or chips imported from abroad with foreign machine package, and then the foreign machine package, and then the foreign machine processed into finished lamp, however, it is still hot, so then we sold superior products abroad and let the foreigners pick and choose. Why is the Chinese high-tech is always dependent on foreign? More certain businesses even “imported” as the back of the brand’s quality.

LED lighting industrial, the biggest problem is “hot”

Look at this summer, it is so hot, and take a look at this summer’s flooding floods. Not saving and environmental protection, it will be more severe.

After suffering a lot of natural disasters, people is just deep introspection. Energy conservation protection has moved. Government strongly support, a lot of enterprise have answered the calling. People are expecting one energy conservation environmental  protection revolution.

LED lighting is indeed the new energy-saving king, just a few years time, it made known to every family, and took up a hot LED Lights market. The market is hot, but it is helpless and pale. On the led lighting industrial, many of the good news once again full of each big website headlines and impact on people’s ear. Just now and then whoever dedicated people will be got down to as “the wolf came”.

We try to look at the LED energy conservation principle:

One, convert the electrical energy the maximum into light; two, make the most suitable for human visual senses light.

When we put the LED lamp compared with the traditional energy-saving lamps, we can clear judgment, LED lamps are energy-saving. Here, everyone will think that energy saving will be OK?

Let’s look at how the led lighting industrial affect the market. the heat issues, life issues, weight issues, efficiency issues, lighting issues, the price. In fact, more than six come from the energy-saving LED lighting principle link.

First, since there are heat issues, it means that the LED lighting and light don’t convert the lighting energy as maximize, even worse than the common fluorescent lamp.

Second, since the high heat production of the LED to the point of view can affect the cooling temperature, to the point of view, the temperature can be seen in general. led lighting industrial source, what kind of material can withstand up to tens of thousands of hours of hot baking? Of course, there will be such a high-quality materials, but the price would be prohibitive.

Third, about life issue. In fact, it is very simple. The heat of the LED chip will affect the life of the LED lighting source itself, resulting in bad light, but also affect the life of the LED lamps, PCB driver board.

Technology trends of led lighting product chips

Austria microelectronic sensor driving lighting department director Sajol Ghoshal points out, to promote the continuous development of led lighting product technology is the main factor of LED Lights regulations. At present, the construction of the new power plant has become very expensive, so in the future ten years, governments around the world are looking to significantly reduce energy consumption. In a building, a high percentage of energy consumption come from lighting. Therefore, the new forced regulations will affect lighting system design and installation of applications. The European Union is planning to phase out the inefficient light bulbs and has formulated regulations for commercial lighting.

From the historical perspective, led lighting product is a rough control of the electrical load, with a simple switch manual control can be further refined control. For example, the lighting is a rough control of the electrical load, with a simple switch manual control that can be further refined. For example, the California Assembly Bill 32 regulations require the building to 2018 to reduce energy consumption by half. Other building codes, such as California, the Title 24 proposed more specific requirement. Such as requiring the implementation for daylight through windows and skylights capture to reduce energy consumption, and requiring the building equipped with an automatic lighting control system. Currently, low-cost passive infrared detectors has been rarely used in the room. Through building system to control lighting can greatly reduce energy consumption, and provide users with a highly optimized lighting. In this regard, it is clear that there is still a long way to go LED Panel.

Therefore, to use the advantage of  LED power and  flexible lighting control will be the main trend in the next generation of lighting systems. The program allows the lighting system to adjust the brightness and color of the led lighting product of environmental changes in order to meet the environmental requirements, such as when there is sufficient daylight in the room or no one in it, the method can automatically reduce energy consumption.

Meanwhile, with the development of LED Tunnel residential and commercial lighting applications, the demand for dimming increases, but the incandescent lamps which used in SCR dimming is still here, so the dimming driver IC architecture design need to face a wider range of dimming compatibility issues.
