Tan Changlin, general manager of TSMC Solid State Lighting, pointed out that TSMC's solid-state lighting will continue to expand this year, mainly because the LED lighting industry will continue to increase.
For the current revenue share of TSMC, the 矽 substrate accounts for about 50%, and the non-矽 substrate accounts for another 50%. Tan Changlin pointed out that although the ruthenium substrate has the advantage of lower cost than the sapphire substrate, the ruthenium substrate is likely to cause cracking of the epitaxial layer due to the difference in thermal expansion coefficient between the GaN epitaxial film and the ruthenium substrate. The yield is easily affected. However, the LED yield of the TSMC solid-state lighting substrate has been raised to a good level, and the company has the strong capacity and technical backing of TSMC. These are the advantages of TSMC.
Tan Changlin further stressed that TSMC solid-state lighting is quite optimistic about the growth of the Southeast Asian market, and the company will also seek opportunities to indirectly cut into the Southeast Asian market by shipping LED chips to the lighting factory. He believes that the current nuclear power plant disputes are getting worse and stronger, and Taiwan's electricity price is too low, there is room for increase in the future, so the demand for LED lighting will continue to grow in the future, he believes that the LED lighting market will be quite in the next few years. Exciting.
Zhang Zhongmou, chairman of TSMC, said at the law conference that the LED industry has recently been more friendly, and TSMC solid-state lighting has also contributed revenue in Q4 last year. He is optimistic that this part of the growth this year will be " Very significant" (dramatically).
Toggle switches, also called On Off Toggle Switches, is often used as the switching device of the equipment stalls. Meanwhile, we are also offer our customers Key Switches , Metal Switches, Automotive Switches, Push Button Switches, etc.
The Electrical Toggle Switches is a manually controlled Toggle Switches similar to the dial switch. Most of this Latching Toggle Switches are widely used in on-off control of AC and DC power circuits, and are less commonly used in circuits of several kilohertz or up to 1 megahertz. Let's take a look at the following.
1. Splash-proof knob button switch
The panel is installed with a splash-proof `O` ring seal, and the knob is a ball. It is a splash-proof ball button knob switch. Its terminals are in a straight line and the bottom of the terminals is sealed with epoxy resin. Strong corrosion resistance, suitable for automotive parts
2. Vertical Mount Right Angle Toggle Switch
The vertical mounting of the terminals and the terminal pins are right-angled, so it is a vertically mounted right-angled toggle switch. Its contacts are gold-plated and highly reliable. Mostly used in anti-theft devices, alert system.
3. Bipolar single toggle switch
At the same time, the switch breaks the phase line and the N line and controls one branch. Therefore, it is a bipolar single toggle switches. The contacts are in 3PDT form and are used for multimedia speakers and stereos.
4. Standard surface mount unthreaded toggle switches
The terminal adopts the standard mounting mode. Its sleeve has no thread. It is called a standard surface mount screw-less switch. The contacts are SPDT and its electrical life is as high as 55,000. Used for medical equipment
5. Horizontally mounted right-angle toggle switch
Compared to the vertical switch, it only changes direction to horizontal, so it is horizontally mounted right-angle toggle switch. The contacts are double-pole double-throw and the bottom of the terminal is Epoxy Seal. Mostly used for computer peripherals.
