When the incandescent lamp is sealed into the order of history, and the energy-saving lamp bulb did not build a market "darling".

"Now there are fewer people buying energy-saving lights, and many young people buy LED lights when they are decorating their new homes." Liwan District South Road Guangzhou Decoration Material City Lighting City bright sunny lighting consultant Mr. Huang told reporters, energy-saving lamps produce light flicker, energy-saving lamp will flash the high-frequency electromagnetic radiation, long-term use is easy to damage the eyes.

On the other hand, according to insiders, energy-saving lamps in the promotion process because the price is higher than the incandescent lamp power consumption deficiency problem several times, widely criticized, such as PHILPS, NVC representing the brand products in 2011 to have been checking out the actual power consumption is more than the marked value quality problems. Since 2013, the NDRC is included in the "semiconductor lighting industry energy-saving product promotion plan" LED bulb because the price is too expensive, not resistant to smoke, less application of lighting problems, encountered many bottlenecks in the promotion.

In the new market environment, the LED filament lamp rises suddenly. Last year, Japan's Matsushita (Panasonic) of the glass bulb shell full light LED bulb launch, because it can achieve the full light effect, and the appearance is similar to the traditional tungsten filament lamp, with antique style, popular European and American consumers. As a result, many mainland LED vendors have followed suit to follow suit, so in many domestic and international LED exhibitions and related lighting exhibitions, almost every booth will see LED filament lamp.

Reporters learned that, LED filament, also known as LED lamp post, and the LED light source is different, LED filament 360 degrees full angle light-emitting, and without the lens, the realization of three-dimensional light source. Can be applied to crystal chandeliers, candle lights, ball bulbs, wall lamps and other LED lighting products.

OPPLE lighting technology engineer Mr. ho told reporters that the cost of raw materials by LED filament lamp filament, LED drive power, glass frame, glass bulb, lamp standard lamp hardware, the structure of LED, the highest cost filament (about LED filament lamp cost 60% ~ 65%). At present, the basic price of LED filament at about 3 yuan, a lamp in general use 4 filament, therefore, the cost of the whole lamp at about 15~20 yuan, the ex factory price at about 20~30 yuan.
