Analyze the cost of LED bulbs and explore its popularity

LED bulbs in Japan in 2009 sales price of 4000 yen, is about half of the original, so the demand can be rapidly improved. In 2009, the sales volume of LED bulbs in Japan was about 1 million 700 thousand, which is expected to exceed 4 million in the year of 2010.

LED bulbs began to circulate in the market before 2009, but the difference between the incandescent lamp and bulb type fluorescent lamp is larger, and there are also some problems in brightness. However, in recent years, with the continuous advance of LED packaging to high light, so the problems of the brightness is gradually being resolved. Coupled with the improvement of the surrounding material, reducing the price of LED packaging, product development is increasingly active.

The results of cost analysis for 2009 LED bulbs are shown in figure 1. LED bulb components and material costs account for about 50% of the overall. The cost of these materials, LED packaging accounted for about half. In addition, the installation of the bottom plate, the circuit board and the proportion of heat sink is also high. It can be said that in the future the trend of these materials will have a great impact on the sales price trend of LED bulbs.

Figure 1:LED bulb cost analysis Techno Systems Research (TSR) data. In April 27th, the seventh session of the TSR Conference on the rise of the LED business on the 2010, the company's professional analyst will detail the latest trends in the new generation of lighting represented by LED bulbs.

Among them, accounting for about half of the cost of LED packaging development is the key factor in the popularity of LED bulbs. In recent years, the improvement of LED packaging, although the expansion of LED bulbs and reduce the sales price of the product price, but the cost and performance is still a problem to be solved. Performance, the current market circulation of LED bulbs are mostly equivalent to 40 ~ 60W incandescent lamp products. In order to further improve the brightness, the need to increase the number of LED packages, or the use of high power LED package. Therefore, the need to improve the heat dissipation.

However, changes in the performance of the LED package and improve heat dissipation may lead to LED packaging, heat sink, the installation of backplane and circuit board, etc.. Therefore, the development of both at the same time to take into account the low cost and high heat resistance of the material is the first priority to address the issue.

At present, most of the companies engaged in the business of LED bulbs in fact by controlling the development costs and installation costs to respond to the rapid decline in market prices. In addition, many manufacturers believe that the low price of the Department of the material to catch up with the price of LED light bulb Market decline". Current LED bulbs from the package to the heat dissipation structure are in the testing phase, is expected in 2010, the market price will continue to decline, so in the medium and long term requirements will reduce the cost of material.
