LEDs become "green" lights

LEDs become “green” lights

Although the price is about 20 times more expensive than incandescent light bulbs. But LEDs last longer and consume less power, a saving that users begin to realize. Prices are also falling as retailers want to attract customers and manufacturers to improve the technology. And because the light of the LED bulb is from chips, companies can develop software applications that help users control the light bulb, even changing the color of the light with tablets and smartphones. intelligent. Apple sells a set of three balls, made by Philips, with the hardware controlling them for about $ 200. Last year, LED sales only increased modestly by about 3% in the interior market, but many forecasts in 2014, sales will increase higher. The most common type A bulb will sell more than incandescent light bulbs in 2014, according to IMS Research, an electronics research firm. And Type A LED bulbs will become the most popular in 2016, reaching nearly 370 million in North America, compared with 33 million last year, the company predicts. Philips sold 20% of its LED bulbs last year alone, according to Ed Crawford, general manager of the segment. Incandescent bulbs are cheap but inefficient, wasting most of their energy because they generate heat when electricity is applied to the filament to brighten them. The government has been calling users to choose other technology for many years, in addition to creating barriers to the manufacture and import of inefficient bulbs. Previously, the emergence of compact fluorescent light bulbs to replace incandescent bulbs was quickly faded, because users were dissatisfied with the coarser light quality, the bulbs gradually warmed up, making it difficult to do. dimmed, and moreover contain harmful materials. LED bulbs are more expensive, but offer better light and...

Ensure safety when using electricity

Ensure safety when using electricity

According to the Department of Industrial Safety and Environmental Technology, Ministry of Industry and Trade, every year, about 400 to 500 electrical accidents occur, resulting in 350 to 400 deaths and hundreds of injuries. 70% of the accidents are caused by unsafe in the process of using electricity at home, daily activities … It is a fact that at present, the units in charge of electricity supply (the Electricity sector) mainly care about safety from the grid to the circuit breaker or the main circuit breaker, while inside the household, the electrical system questions and use arbitrarily, there is no specific guidance of the professional agencies. Many rural areas, remote areas, electric poles are utilized by trees or taking advantage of terrain and terrain to hook electricity; cables and wires are also used by cheap and processed materials so it is very dangerous and prone to fire. Also, due to lack of knowledge and advice when designing houses, designers only pay attention to grounding, lightning protection, not the safety grounding system for indoor electrical equipment. Therefore, when the leakage occurs, the possibility of users being electrocuted is very high. Another noteworthy point is that usually when producing electrical equipment, manufacturers warn and make notes on the power cord, on the plug, making 3-pin drives, in cables with 3 wires, in addition to 2 wires. The source also has a third yellow-green wire, which is the ground wire against electric leakage. But users do not care much, sometimes using a third foot cutter to connect with green gold wire to easily plug into the 2-hole drive in the house. This creates the risk of electric shock when using electrical equipment.   Not only related to the installation of electrical systems, according to experts,...
