Read the uneven quality of low-power LED lamp lights may accelerate as the fatigue

LONDON June 3 news: According to "Evening News"report, now on the market there are many LED reading lamps, whether theyreally like it advertised as able to "protect the eyes"mean? Held yesterday at Fudan University in Shanghai 2011, trends in lightingtechnology and applications forum, experts pointed out that the market level of uneven quality LED reading lamp, LED Tiffany Table Lamp, and many can not protect the eyes.

It is reported that LED lamps on the market of varying quality. Since most of these use low-power LED lamp as light source, thetotal power is not enough, reach sufficient illumination. In addition, these LED lamps have on eye health effects depends on the use of functions. If a bedside lamp, night light, control the degree not ask for much, the impact could not; but if as a reading lamp,illumination will accelerate less visual fatigue, not conducive to the protection of eyesight.

So, people should pay attention to the purchase of what reading lamp? Fudan University School of Information Engineering,Lamps and Lighting Lighting Research Institute, Associate Professor Lin Yandan pointing: "First of all to observe the distribution of the product itself is uniform injection of the spot; followed and do not feel particularly dark, which is the average illumination is not enough; In addition, written under the lights Something, feel the light no direct stab to the eye line; there is natural light and color to some, not white. "

In addition, the experts pointed out that the average consumer in the purchase reading lamp, do not have the expertise and specialized measuring instruments, the performance on the reading lamp can only observe from the results of product identification and get some idea. Therefore, the proposed purchase through normal channels, through the formal certification ofproducts to prevent some bad products shoddy.

It is understood that the development under the Lighting Research Institute of Fudan University's transformation plan, the whole of Shanghai now has more than 40,000 classrooms have been completed the transformation of light environment. According to the Shanghai Education Commission, entrusted by the relevant health departments and three years of visual tracking eye point of view, this is conducive to curb the incidence of myopia in Shanghai in pupils.

Forum, some experts say, LED Police Lights are still much room for improvement.

"If I give my son to buy a reading lamp, I will not buy LED's," deputy director of Institute of Fudan University, Shan-side source said yesterday that, unless it is from large companies and the international certification of products, a lot of LED current In the light principle, is not suitable for table lamps made, "LED lights are more Blu-ray component, is not conducive to visual acuity."

Lighting Research Institute of Fudan University in recent years, reading lamps on the domestic market made a lot of testing, in addition to Blu-ray problem, said associate professor Lin Yandan, LED lamp products a few years ago there was a general problem of lack of flux, "both relatively dark light , there is the question of color, see things in the LED lamp when the following color distortion. At the same time, can shine only a small part of the distribution of the light pattern is called improper. Besides, it's relatively light emitting point direct look at it, but also feel very harsh, "Linyan Dan said that at present there is no LED lamp is complete with national standards, therefore, particularly good quality in addition to individual products, and can not play the role of a good eye.

LED bar Light - A unique invention in light-bar technology

Among many advantages, few of these are briefly discussed below: 9. Low maintenance cost 10. LED light bars are considered to be extremely energy efficient 11. An option to go from low profile to high visibility and vice versa 12. Built-in bright color lights

Low Maintenance Cost As the labor cost has increased with a larger rate, the advantage of low cost maintenance has gained more importance. A LED bar light has no or low maintenance cost unlike non-LED light bars. The LED of these lights is itself so powerful that it does not require any rotating motor or any other moving part, which in turn reduces the maintenance cost. Halogen Bulbs due to its high maintenance cost were completely replaced by a LED bar light.

Extremely Energy Efficient By looking at the increasing demand of energy, LED light bars were introduced. Earlier several efforts were made to generate more energy but they failed due to the high incurring costs. In comparison to earlier introduced halogen or strobe bars, LED bar light produces around one-fifth to one-fourth of more energy. Presently, police vehicles are incredibly benefiting from it because it allows consistent usage of several other forms of energy snapping equipments including camera, radios, radar and computers. LED bar light fulfills the need of a fully equipped police unit, proving to be extremely energy efficient.

Other Advantages and Disadvantages In addition to the few mentioned above, there are several other advantages of LED bar light. Some of these are listed as follows:

o Built-in bright color lights making the vehicle more noticeable to other motorists.

o Higher visibility

o It gives the user an option to go from low profile to high visibility and vice versa. Therefore, if the user doesn't want to be noticed in heavy traffic, he/she has an advantage of switching to low profile from higher visibility and can switch to higher visibility in crises situation.

Every product lacks in some or the other area. Similarly, LED bar light also lacks in the area of takedown lighting. There are several agencies that completely depend on mounted spotlights in order to provide take down lighting. Majority, of the produces have overcome this problem by incorporating this ability in their led bar light device. In this particular area, halogen bulbs still have an advantage over LED light bars, although newly introduced LED equipments are trying to overcome this issue as quick as possible.

While selecting your bar light, don't forget to purchase, the control head (unit that controls light bar functions as well as the siren). It's important that you properly check the equipment's functionality before purchasing it, because there are few older versions that are not equipped with complete programmability. Continuous inspection of LED bar light is essential so that units can be replaced when required.

New trends in green lighting: LED lights and lamp race

LED lights great "lose ground" of the situation, and other new energy-saving lighting products also showed the courage to enter the market. "As a new energy-saving lamp products, causing more and more attention, has become the trend of green lighting products, in more and more energy-saving projects have been accepted applications." Shanghai Hongyuan Lighting & Electric Co., Ltd. Chairman Li Weide said. When the low-carbon, green, energy-saving consensus of the whole society, changes in the field of lighting industry along started. The LED Grille Lamp, lamp light source, represented by such new products will replace the traditional energy-saving lighting, green lighting market compete. It is understood that fusion lamp light, electricity, magnetic technology, and is a new generation of integrated circuits using IC lighting. Because it changes the electrical energy into heat energy by the then into light-emitting principle, directly from the electrical energy into light energy, thus saving a lot of energy to bring the energy consumption.
Analysis of cognition from the current market, LED lighting lamp and a far cry. LED lighting has become the industry generally agree the direction of future development of new sources, the major lighting companies have also invested heavily in R & D LED lighting products, LED lighting products on the market is also very rich. The lamp market awareness and penetration is relatively low, only a few businesses to invest in energy R & D lamp products, but also with non-polar light source supporting very poor lighting products, which seriously affected the discharge lamp applications in the market and promotion. "The current development constraints lamp or the lamp in the final analysis the biggest obstacle to market penetration is not enough, the owners know enough about them." Li Weide said.
As a leading China market, two types of energy-saving green lighting products, LED lamps and lamp what would be even better in the race to the future market? Industry which has been debated.
From the price in terms of, LED lights and lamp compared to conventional lighting in terms of expensive. Most of the LED light chip technology with foreign countries, prices are not low. Although the lamp is slightly higher than the price of traditional lighting, but because of their energy contract management model can be used, the user can advance a "zero" input, so biased by the users.
Technically, the discharge lamp and LED lighting technology used in different ways, but both of the product life, energy saving and other aspects far behind.
From the application of the type of view, LED lights and lamp each division, the small power LED light monomer, resulting in projects with high-power LED lights on the lamp can not be compared with; Similarly, in a low-power landscape lighting, lighting direction, the display, the electrodeless lamp and not LED. "The function of illumination, polar light LED light source has obvious comparative advantage." Li Weide frankly, LED lights in the presence of functional lighting in the area early so that the light efficiency is low, big bad light, thermal solutions to address bad, poor product consistency and other defects. The lamp light source in this emerging field of functional lighting is light efficiency, light is small, and other advantages can be instant start.
From a technical point of view of maturity, the domestic quality is not perfect LED products,  LED Police Lights most of the core chip business by foreign imports. LED lights with heavy constraints by foreign patents than patents related lamp is firmly in the hands of domestic enterprises, the current international market, 90% of the polar lights made in China, many enterprises discharge lamp lighting production technology has reached international advanced level.
