The LED chip industry flourished in China as the government provided capital subsidy to small companies to buy MOCVD tools which help in making these chips. With oversupply, prices have crashed to below costs leading to bankruptcies. China is now seeing the 3rd Green Industry Bubble Bursting with LED chip manufacturers in China going bankrupt […]
Train Accidents in India are starting to happen with surprising regularity with hardly a month passing by without a major collision or accident. Small accidents seem to be happening every day with news report of a collision not generating any mindshare these days. Road Accidents in India too happen with great regulatiry with some estimates of 1000 Road Deaths happening in India every day . This is due to government and people apathy towards safety regulation and following of laws and norms. It is just not resticted to trains but encompasses the entire system such as fire safety etc. Without a major change in the people attitude towards safety regulation expect such accident and waste of human life will continue to happen.
A light-emitting diode (LED) is a special type of semiconductor device that emits visible light when an electric current passes through it. It has two sides – one with an abundance of electrons called “n-type semiconductor” & the other with bunch of holes that need to be filled by electrons known as “p-type semiconductor “. With the help of these p-n junctions, these semiconductors can control the direction of the flow of electricity. The LED works on the principle that when electrons lose energy, they move from a higher orbit to a lower orbit. The energy lost is in the form of light photons. The color of the light emitted depends upon the frequency of the light photon released. The higher the frequency, the greater is the energy release. Gallium nitride is the light emitting ingredient in LEDs. It is used in the sapphire-based blue and green LEDs. Its practical application is in traffic signals & in lasers in high-definition DVD players.
LED TV is an LCD TV that uses LEDs to illuminate the display. these new sets use LED backlights rather than the fluorescent-type backlights used in most other LCD TVs. LED-backlit LCD TVs cost twice more than standard LCD or plasma TVs. Because of the slim line design of these LED tvs not only is less packaging used, but the vast reduction in overall weight means reduced transport and fuel costs. Most of the LED TVs are mercury free making them extremely eco friendly.
xit Sign is an important legal safety requirement, in case of any emergency like fire in any building. An LED exit sign is an illuminated sign that uses LED light to illuminate the word “EXIT. The traditional incandescent & fluorescent technology that are used, consume large amounts of energy & also require frequent maintenance. Since these signs operate 24*7, there is a need to replace incandescent bulbs with efficient models with long lives to help reduce maintenance cost and effort. They offer savings of up to $300 per sign in reduced energy, materials, and labor costs as compared with standard incandescent models. LED exit signs are an array of very small LEDs either red or green in colour arranged in a line or circularly. Many exit signs come with a battery backup since they need to remain lit at the time of emergency, when a building’s power is interrupted. It is a good option that buyers should look for. LED exit signs work at 120V or 277V. Exit sign manufacturers have made these products available at very competent prices. They are also easy to install. LED exit signs need to be approved for use by UL (Underwriters Laboratories) and should be compliant with local and federal building codes.
Note none of the Indian automakers has a decent EV or a Hybrid selling in the Indian market.Foreign markets on the other had are seeing fierce competition amongst major auto makers to gain a first mover advantage.GM,Nissan,Toyota are the leader in this market with other car makers also in the process of getting in.Hectic alliances and JVs are being forged as this market segment promises to be the fastest growing as the governments give massive subsidies and push.It remains to be seen whether the government in India can push given its record.
