Demand growth LED industry enters rising channel

The continued growth in demand for lighting has driven the LED industry into a one-way uptrend channel. With the further restrictions on the use of incandescent lamps and the decline in the price of LED lighting products, LED lighting has ushered in the opportunity of rapid development. Combining the data of major manufacturers and research institutions, it is expected that the shipment scale of LED lighting will exceed 100%. The company is also expected to receive more than expected earnings. The LED enterprise revenue in Taiwan has always been an indicator of the LED industry's prosperity. Although December is a low season in the traditional sense, the chip industry's chip revenue in December increased by 59% in December, and the overall package revenue was 5.3 billion. The revenues of mainstream companies such as Ronda and Jingdian have shown a gratifying trend. Among the large packaging companies, Everlight's December revenue was NT$2.26 billion, a year-on-year increase of 70%. Benefiting from orders for lighting and backlights, the company expects shipments in the first quarter of this year to continue to grow. Lunda Electronics benefited from the return of notebook computer orders, Korean mobile phone manufacturers' flash and TV backlight demand. The December revenue was NT$1.097 billion, down 5.84 from November, and the growth rate reached 55. In the first quarter, Jingdian's revenue in December reached NT$2.047 billion, a slight decrease of 1.36, a year-on-year increase of 78.8. The characteristics of LED lighting products are outstanding. From the recent technological developments, the light source efficiency can reach more than 200lm/w. At the same time, the price of market terminal lighting products has continued to decline. The products of companies such as OSRAM and Cree have been reduced to around US$10, while the price of energy-saving lamps of the same brand is about US$5. Considering the great difference in service life, The actual use cost of LED lamps is cheaper than ordinary energy-saving lamps. From the perspective of the division of the LED industry chain, it mainly includes four major sectors: LED raw materials (MO source, luminescent materials, etc.), LED chips, LED packages and LED lamps. From the perspective of benefit, the first benefit is the downstream with channel advantages. Lamp manufacturers, such as Sunlight and Dehao Runda, followed by LED chips and packaging, with the growth of demand scale, capacity utilization has been rapidly improved, LED raw material prices have also been boosted, such as Nanda Optoelectronics MO source and rare earth luminescent materials from Keheng. From the perspective of functional division, it is mainly divided into LED lighting and LED backlight. The industry is more optimistic about the development of LED lighting. The recent situation of Ruifeng Optoelectronics also verified this judgment. The management of the company said that on the basis of stabilizing the LED LCD TV market, it has increased its efforts in the field of LED lighting and achieved corresponding growth in sales and profits. From a growth perspective, since the penetration of LED backlights in panels and smart terminals has exceeded 90, the future growth of backlight scale will mainly come from natural growth, and the growth of LED lighting will usher in the penetration and natural growth.

Pulse Valve Diaphragm
The pulse valve diaphragm is a whole high quality rubber diaphragm, which is installed with the riveting head which is used to plug the compressed air pipe or the outlet of the plugging valve. The diaphragm is a whole high quality rubber diaphragm with the hole of the discharge and unloading and the bolt holes with fixed support. It is the key control part in the electromagnetic pulse valve.
Working principle
The pulse valve diaphragm divides the pulse valve into two air chambers. When the electromagnetic pulse valve is connected to the clean compressed air in the dust cleaning system of the pulse Bag Filter, the compressed air passes through the throttle hole and enters the rear air chamber. At this time the pressure of the rear air chamber is close to the outlet of the valve, the pulse valve is in the closed state and the pulse control instrument is output. The signal is to move the armature of the pulse valve, the gas chamber is open after the valve, and the air chamber is opened, the rear air chamber is quickly lost, the diaphragm is moved back, the compressed air is blown through the outlet of the valve, the pulse valve is in the open state, the output of the pulse control device disappears, the electromagnetic first lead armature of the pulse valve is reset, and the rear air chamber is deflated through the hole. When the pressure rises in the rear air chamber, the pulse valve diaphragm is close to the outlet of the valve, the pulse valve is in the closed state, the injection stop is stopped, and the size of the long and short gas amount of the injection time is controlled by the controller.
technical requirement
The pulse valve diaphragm is a flexible mechanism that requires constant opening and closing to control air circulation, and requires good flexibility, and requires as high as possible sealing. Therefore, the material of the diaphragm is directly related to the life and use of the diaphragm, in other words, the pulse valve membrane. The good or bad of the film directly affects the working stability of the dust cleaning system of the pulse bag filter, and is directly related to the cost of the use of the dust removal equipment. The ordinary diaphragm has the promise of the service life or the number of action, and the use of the high quality pulse valve diaphragm can directly reduce the cost of the use of the dust removal equipment.
structure performance
It is made up of two or more layers of glue. According to its shape, the method of membrane pressure is divided. According to the requirements, we can make different kinds of rubber and different fabric diaphragms. The properties of the blend of butadiene rubber and polysulfide rubber for diaphragm, the properties of the adhesive used in the canvas disc diaphragm (often called diaphragm), and the characteristics of some silicone rubber, fluororubber and chlorohydrin rubber film developed in recent years are explained as follows.
The working temperature range and pressure range of the diaphragm depend on the glue type, fabric and structure. The diaphragm can work at -50~100 centigrade and 0.4~0.8MPa, and fluorine rubber and silicone rubber diaphragm can work at -80~232 degrees Celsius. The chlorohydrin rubber diaphragm can work under 0.4~0.8MPa pressure. It has good tightness, aging resistance and life expectancy.
