LED bulbs will become the assembly industry?

September 10th, Panasonic released the LED bulb. Hitachi lighting (Hitachi Lighting) also recently (September 16th) announced the support of dimmer LED bulb. So far, Toshiba lighting technology (Toshiba Lighting & Technology), NEC Lighting, MITSUBISHI electric OSRAM (Mitsubishi ELectric OSRAM) and other 5 major lighting manufacturers have launched a LED bulb. The price of each manufacturer's product is not much difference: does not support dimmer about 4000 yen, support dimmer about 5000 yen. About half the price this spring. The low price of the fuse is lit just last year to get involved in LED business of SHARP lighting, Toshiba lighting technology followed, launched with the price of the product, the remaining 4 companies between September and one by one, released a new product in August. May be affected by this, newspapers and the Internet, "LED lighting", "LED bulb" frequency is increasing.

In the interview, the author has also heard that now some of the LED lighting overheating sound, but with the advent of this new LED light source, lighting appliances and lighting industry is undoubtedly usher in a turning point. "The September 21, 2009 special" electronic "LED lighting Warring States era" devoted to the dynamic change of the lighting industry.

This change is slightly different from that of the main illumination from incandescent to fluorescent. Prior to the lighting by light bulbs, fluorescent lamps and other light sources and the installation of light sources (lamps). Incandescent bulbs, fluorescent lamps are so. Therefore, manufacturers have a certain degree of division of labor. But LED is shaking the foundation. SHARP LED light bulb with a dimming function is a good example (although there is a delay in listing time). Although the shape of the lamp, but the function is lighting. Due to get rid of the structural constraints of the lamp and the lamp, it is possible to achieve a more free commodity design.

Moreover, the original belongs to the equipment industry, the production of light bulbs are also gradually to the procurement of LED packaging and power production and assembly industry change. Examples of their products are NEC Lighting with iRIS euro LED (IRISOHYAMA) of the light bulb. At first glance, two products exactly the same. I originally thought it was NEC Lighting to iRIS OEM and delivery. One asked to know, these two products are independent design. Just because of the external heat sink using the external procurement of standard products (may have a certain degree of customization), so the appearance is similar.

With the bulk of the components, it goes without saying that, even without the knowledge of electrical design and thermal design, but also can create LED bulbs, it may be difficult to form a large performance difference. Like the development of personal computers into a horizontal division of the assembly industry, it is difficult to rely on processing performance differences win. If the basic components - LED packaging performance has been improved, the situation will be more serious. Because of the power consumption, brightness, color rendering performance depends largely on the performance of the packaging. If so, LED bulb dispute is bound to become a mere price war.

It is possible for the above concerns, lighting manufacturers want to get rid of the existing incandescent bulbs and fluorescent lamp shape and the limits of the lamp mouth, the full development of the new system can play the characteristics of LED lighting. But only 200 million of the Japanese domestic light output is E26 shaped, E17 shaped, and can not immediately stop production. So there is still a lot of demand for LED lighting installed on existing lamps. Moreover, LED lamp life is long, the replacement demand is not high, must seize the opportunity to win. In the future, the low price will be what speed? Industry enterprises will increase to what extent? I wait and see.
