2000 yen LED bulbs listed

June 2009 SHARP launched a price of 4000 yen LED lighting, the company to follow, in one fell swoop forward low price. After just over half a year or so in 2009 of December, the price of only about 2000 yen LED bulbs began listing.

Is one of Japan's Orion motor (OrionELectric, headquarters: Fukui Echizen) together with the Doshisha development, the market in December 14, 2009 a series of "Luminous" (hereinafter referred to as Luminous bulbs). The power consumption is 6.6W, the total flux is 420lm (white), equivalent to 60W incandescent lamp products priced at 2480 yen (including tax); the power consumption is 4.7W, the total flux is 310lm (white), equivalent to 40W incandescent lamp products priced at 1980 yen (including tax). In addition, the chamber of Commerce in December 22nd Otsuka to 2380 yen (including tax) of the market price of the Korean FAWOOTechnology development of LED lighting "Lumid as-CL" series. The series includes a power consumption of 5W, total luminous flux of 292lm (white) to replace the 20 ~ 30W incandescent lamp products. Orion motor and Doshisha jointly developed "Luminous lamp", equivalent to 40W incandescent lamp price is 1980 yen, a lower price is realized. The characteristics of the Korean Chamber of Commerce listed Otsuka FAWOOTechnology production of LED lighting "Lumidas-CL" is the use of an elongated shape, from the inner side of the heat dissipation through the heat sink hole central part. Equipped with dozens of LED package "to 1980 yen for the goal to promote development" (Doshisha lifestyle business department master lifestyle merchandise minister, director of the underground main) key to achieve low-cost Luminous lamp bulb is equipped with a lot of small LED package. Equivalent to 60W incandescent lamp products are equipped with 40 LED package, equivalent to 40W incandescent lamp products are equipped with 34 LED package. China lighting society seventh LED packaging technology training m.l.s electronics domestic LED package share of 30%-40% high power LED packaging technology of juke lighting in LED packaging and application of technological innovation to achieve brand objectives China lighting society eighth LED packaging technology training patch type LED and high power LED package can establish a strong competitive advantage, Huayang Zhongzhou photoelectric LED packaging industry is the largest single financing was voted 5000 all star power will become the first domestic well-known LED packaging production enterprises, the leading enterprises in the field of LED package nationstar (002449) today began to purchase Guangdong LED packaging production accounts for about half of the country all over the world. In the past, many manufacturers in the LED light bulb is used in the input power LED package for 1W level. The Luminous lamp is equipped with 100 LED package class mW. Although the number of packages required to be increased, but the total cost of reducing the LED package (Doshisha). However, to install a large number of LED packaging, it is difficult to reduce the floor area of the installation. Many manufacturers in order to make the LED bulb suitable for existing lighting appliances, the diameter of the LED bulb is controlled in the same as the incandescent lamp 60mm, but the Luminous bulb increased by 4mm, reaching 64mm. Installed 40 small package in LED is equivalent to 60W incandescent lamp products. The heat of the bottom plate can be transferred to the heat sink through the metal plate. A small LED package and to improve heat dissipation. Due to the small heat source scattered on the LED floor, so there is no place where the temperature increases, the temperature of the floor is easy to become uniform. Luminous lamp LED mounting plate made of metal plate in is equivalent to 60W incandescent lamp products, and the product is equivalent to 40W incandescent lamp is the floor instead of metal base resin. "Although the thermal conductivity is relatively good, but there is no need (in the LED package with a small amount of heat is less) in the use of more expensive metal substrate" (Doshisha). Equivalent to 40W incandescent lamp products with low cost floor plate also for the price of less than 2000 yen made a great contribution. A circular configuration of LED Lumidas-CL and Luminous by using the method of light bulb equipped with a large number of small LED package. Equipped with a quantity of 20. In addition, using low cost structure considering easy assembly, such as assembly of resin used in the shell without adhesive fastening (SnapFit), LED, the power supply circuit is connected with the bottom plate mounting plate and the lamp adopts the method of welding outside. In addition, South Korea has received LED lighting safety standards certification. With hollow shape tapered, and the start of the 3 layer structure were lens, mirror and heat sink from the outside. The LED package is mounted on a circular bottom plate and is mounted on the root of the heat sink. Appearance is elongated shape characteristic, at first glance will feel no fins, but actually fin embedded in the central part of the bulb. The 3 layers of the lens, the reflecting mirror and the radiating fin are respectively arranged on the outer side, and the ring-shaped LED mounting base plate is arranged at the root of the radiating fin (near the lamp port). The surface lens with small holes, the air can be in and out between the through hole and the central part of the external heat sink. In other words, Lumidas-CL uses a heat dissipation structure from the inside of the through hole of the heat sink. In addition, in order to facilitate the flow of air, the utility model is provided with a notch on the bottom board of the power supply circuit which is arranged at the lower part of the radiating fin. In this way, the air can flow in and out of the bulb.
