Matsushita electrician talks about the popularization strategy of LED lighting equipment

Matsushita will be launched in October 2006, 600LM brightness equivalent to 60W incandescent lamp LED lighting equipment. The device uses a self-developed high power and high color rendering LED unit "MFORCE" (Figure). As the use of white LED, lighting equipment has been widespread concern in the industry. We use white LED lighting in the future will be how to popularize, the reporter interviewed the day before the Japanese lighting equipment giant Matsushita Electric lighting business department of the LED special goods?? director of market development center under the Sumio and LED business promotion department minister Kimura Takashi, business planning team is responsible for the NPC and foufe, residential lighting business planning team is responsible for the goods our people Xipu akira. (Interviewer: Uno Mayuko)

- this product in addition to high power, but also pay special attention to color. Through the combination of the "blue LED + yellow fluorescent material" into "blue LED + Red and green fluorescent material", the color performance is improved. Why should we pay special attention to color?

Matsushita: This is because the LED lighting equipment and incandescent lamps have the same brightness, and similar to that of the incandescent lamp to give objects lighting ", means that the new use of LED lighting equipment, its application will be more and more. Neon used in the past is the use of LED self luminous characteristics. The future will assume the role of lighting objects.

One of the most important indicators in lighting applications is the color rendering. Ra (average color rendering coefficient). Natural light as the standard 100) in more than 80, according to the different locations in the corridor to about 70. But in the table and other places, many times, the most ideal is the same as the museum lighting, more than 90. 20 years ago, Matsushita Electric by fluorescent lamp by dual wavelength into 3 wavelength, improve the color rendering, which has been "very beautiful" that was at home from later companies began to use the 3 wavelength fluorescent lamp.

The past LED lighting equipment due to loss of phosphor wavelength conversion is not the same, and the vision of people of various colors have different sensitivity to red than green low sensitivity, so there is a high color rendering, the brightness will drop the problem. The product is able to get the equivalent of incandescent light enough brightness, so pay special attention to the color.

- this is why the use of lighting products from the market began to put on the market?

Matsushita Electric: LED this has a long life, light without heat characteristics. The easiest to accept these features as additional value is the mall lighting.

Recently, I hope the decoration and other shopping malls will be applied to residential design requirements are also very strong. Matsushita Electric in 2004 from the launch of the designer Apartments (designers' apartments) of the "HomeArchi" products, and won wide acclaim. As for LED lighting, ready to enhance visibility through the market, and gradually expand the market to the residential area. LED is most suitable for the recent market more and more "single room multi head lamp".

-- what do you think is suitable for LED lighting field?

Matsushita Electric: Recently, lighting equipment is gradually moving towards the "one room and more lights" direction. As in the past is no longer the only room ceiling middle position has a light source, but the source configuration to the ceiling and the floor, forming a height difference in the installation position, or to the surface and point light, give the lighting effect change. In addition, to avoid the highlight of the lighting itself, and only hope that the use of light for space decoration requirements are also very strong.

In this regard, because of the use of more light source, so the brightness of each light source is low, and the degree of freedom of the location requirements are higher. Compared with fluorescent lamps, the luminous efficiency of LED lighting is still low, which is not suitable for the whole lighting field. However, the use of lighting equipment, the overall size of the characteristics of the light source can be configured to the existing fluorescent lamp and incandescent lamp can not be installed in the location.

As a multi lamp light source, it is important to be small in size but not in high power. For example, the power supply circuit, even if the efficiency of how much sacrifice, but also the use of small design can achieve a half wave rectifier circuit, the power circuit embedded in the lighting device. Power is small, the need for heat dissipation will also be reduced, so if installed in the aluminum alloy material on the table, but also to ensure the heat dissipation.

- the use of MFORCE commercial products, the price of nearly 100 thousand yen, seems to be expensive.

Panasonic electrician: if used from residential purposes, this price is not a lot of popularity. If embedded in the ceiling of the ordinary spotlights, usually in the 5000 yen to 6000 yen. Price difference of more than 10 times. As LED is concerned, although the introduction of the sale will usually say "long life, the price is high", but the reality is cruel.

For example, claimed that the long life of the product has no electrode fluorescent lamp. Incandescent lamp fluorescent lamp life of 30 thousand hours, equivalent to ordinary fluorescent lamp of 4 ~ 5 times, and the price is also the appearance of the appearance of 4 ~ 5, probably about 4000 yen ~ 5000 yen. The utility model has the advantages of eliminating the trouble of changing the lamp, and the utility model has certain market demand as a new lighting equipment, but the requirement of the bulb is almost nonexistent. It is said that many consumers believe that 30 thousand hours of life expectancy is the norm.

In order to popularize the LED lighting, even with the advantages of long life and installation freedom, compared with the past light source, I am afraid to be controlled to 2 ~ 3 times.

At the same time, the use of LED and fluorescent lamp energy saving

- LED lighting can become the most
