[Source: Gaogong LED's "LED Good Products" December issue (total 60th issue) Wen | Yang Jinglin] LED glass tube with a price advantage compared to other materials, quickly blush in the LED lighting industry, and with its many Advantages have made a subtle change in the pattern of LED tube materials.
According to statistics from the High-tech LED Industry Research Institute (GLII), in the first three quarters of 2014, the total output value of China's LED industry reached 243.9 billion yuan, a year-on-year increase of 27.6%. At the same time, the penetration rate of LED lighting industry value has also increased from around 20% in 2013 to over 30%. It is also expected that the output value of LED lamps will reach 22.2 billion yuan in 2014, a year-on-year increase of 43%.
The expansion of LED lamp market demand has attracted countless lighting companies to invest in it. However, the sharp decline in prices has led to a continuous decline in the gross profit margin of the company. How to improve the cost performance of the lamp has become the focus of attention. In the meantime, many companies have chosen to make a fuss about the material of the lamp, and the glass lamp has since risen.
At present, including National Star, Buddha Photo, Baocheng Xin, etc., whether it is a listed company or a professional lighting brand, have launched the glass tube project. For example, the 330-degree luminous T8-H lamp from National Star Optoelectronics and the 360-degree glass LED fluorescent tube introduced by Shenzhen Pushengyuan (Baochengxin) have been recognized and sought after by consumers.

The industry believes that, driven by market demand, there will be more lighting manufacturers in the future, joining the ranks of glass tubes.
Three kit materials
At present, the material of the LED tube kit mainly has the following three types: the first type, the aluminum plastic tube outer casing; the second type, the glass tube outer casing; and the third type: the full plastic tube outer casing. At present, the common LED tube material on the market is mostly aluminum-plastic, but the aluminum-plastic material is not safe, and the PC material is prone to aging, deformation and short life, which are urgent problems to be solved.
The so-called "glass tube" has obvious advantages such as low cost, not easy aging, high light transmittance and high flame retardant performance. Therefore, there is such a voice in the industry: the use of durable glass tubes to replace the all-plastic and aluminum-plastic tubes commonly used in the market, or will become a trend in the development of LED tubes in the future.
“Since 2008, we started to make aluminum-plastic tubes, which have better heat dissipation performance. However, due to the composition of aluminum, it is prone to conductive leakage and cause accidents. In order to solve this problem, we have developed a plastic tube, plastic The advantage of the tube is that it has good heat conduction and can be physically insulated, but the heat dissipation effect is not good, and it is easy to bend and deform under high temperature." Tang Yuying, sales director of Haining Honghui Energy-saving Lighting Appliance Co., Ltd., interviewed by reporters of "LED Good Products" Said.
According to Tang Yuying, the emergence of the company's glass tube products has solved the above problems perfectly. "The glass tube can be insulated, and the glass tube will not appear aging, yellow line, bending, etc., and the material cost of the glass tube itself is quite low. It can be said that the glass tube is the most cost-effective product at present. It is also an inevitable trend of future development."
However, for most people, the biggest problem with glass tubes is that they are fragile. However, Tang Yuying believes that "this thing does not have to worry at all. Because in the process of packaging or transportation, many manufacturers now add phenol plastic materials outside the glass tube, wrapping the tube, it will not cause the glass tube to break." .
Cai Minghui, chairman of Baochengxin, also said, “In addition to coating the glass tube with the relevant coating, we also added a thin PC inside the glass tube and fixed it inside the tube. The advantage of this is that Even if the outer casing is broken, there is protection in the inner layer of the PC, and the lamp will not break."
