In recent years, major lighting exhibitions at home and abroad have attracted the attention of LED industry. Through each exhibition, it can be seen that filament lamps have gradually become popular in the European market.
From the products that were originally displayed by Asian LED manufacturers, they can be seen in some European lighting manufacturers' booths, and the types of lamps are gradually diversified, even with dimmable filament lamps.
It is understood that at the 2016 German Lighting Exhibition, the filament lamp set off a very high wave, and the recognition in foreign countries has gradually improved.
It is clear that Europeans still have a soft spot for lighting patterns similar to traditional incandescent bulbs.
On April 26th, Shenzhen Qingqing World, Gaogong LED held the first stop of the national tour survey activity of this year - the special seminar on filament lamps, and the "lights" of filament lamps were mentioned by many speakers at the conference.
Jiao Li, product manager of Hongli Optoelectronics, also said that each LED person has a special "feel" for the filament lamp, and now the LED filament lamp finally meets the summer.

Initially, China was a major producer and consumer of incandescent lamps. In 2013, China produced about 4.5 billion incandescent lamps. However, after entering 2014, China, South Korea, the United States, Australia and other countries have begun to transform the overall layout of LED filament lamps.
It is understood that since October 1, 2016, China will completely ban the production and sales of incandescent lamps. Therefore, many incandescent lamp manufacturers will be forced to face transformation. As a result, the LED filament lamp will be heated again.
LED filament is the most critical part of the filament lamp, and its quality will be enough to determine the pros and cons of the filament lamp product. LED packaging manufacturer Hongli Optoelectronics has been studying in the field of filament packaging for many years.
As we all know, due to the existence of light source and solution problems in the filament lamp, there are many disputes for the packaging factory.
At present, the filament substrate mainly comprises a metal substrate and a transparent substrate such as glass, sapphire or ceramic, and both have advantages and disadvantages. Jiao Qi believes that the metal substrate has high thermal conductivity and low cost, no need for secondary “plateâ€, and the process requirements are relatively low, but the metal substrate is opaque, and the light effect and the light-emitting effect are slightly worse than the transparent plate; the thermal conductivity of the transparent substrate is relatively The lower, transparent plate has high light efficiency and good luminous effect. However, after the package is completed, the transparent plate needs to be soldered at both ends. The transparent plate is a connecting structure, no dispensing process is used, and the rear section needs to be cut.
Recently, Hongli Optoelectronics has also introduced a variety of LED filament packaging solutions to meet the needs of filament lamps.
