The automobile company Renault has announced that in the near future it will release two models that will please fans of green cars. More precisely, it will be electric vehicles that will be assembled on the basis of the popular Kangoo and Fluence models.

The Fluence model was marked Z.E., the platform of the new sedan was extended by 130 mm. A powerful electric motor is installed in the car, which will make up the company 250 kilogram lithium-ion batteries.

But the engine power and the speed that it can squeeze out will pleasantly surprise and, moreover, it can create not bad competition for gasoline ...

Technological advances in the LED industry. What is the secret to the longer life of the new LED lighting fixtures for indoor lighting?

The market for LED technology is growing rapidly and the range is filled with various new products. In general, for LED lighting, this market niche is an unplowed field. After all, the elements themselves, LEDs, are practically durable, mainly due to low heat transfer and low consumption, they work on average 50,000 hours, namely 5 years. This makes it possible to assemble ready-made equipment, where it is not necessary to provide the dimensions of bulbs or the possibility of replacing light elements, so that LEDs can be turned into bulbs, searchlights, lamps, in a free art form and format, you can combine colors, enhance the precision with optical lenses ...

What advantages can the housing and communal services get when switching to energy-saving LED products? Comparison of a conventional NBP lamp with an LED analogue.

Housing and communal services is one of many enterprises that will without fail have to soon switch to energy-saving technologies, and the transition will be guaranteed by the State, which is strictly aimed at radical measures, namely the transition to energy-saving LED products.

Our topic will be related, first of all, what energy-saving products are offered for this sphere and what benefits can be obtained when using these products? ...

The principle of operation of this device and the pros when using it.

As you know, incandescent lamps and the so-called halogen lamps very often fail. This is often due to unstable mains voltage and the very frequent inclusion of lamps. Even if low voltage lamps (12 volts) are used through a step-down transformer, still the frequent switching on of the lamps leads to their rapid combustion. For a longer service life of incandescent lamps, a device for smoothly switching on lamps was invented.

A device for smooth start-up of incandescent lamps ignites the lamp spiral more slowly (2-3 seconds), thereby eliminating the possibility of lamp failure at the time of filament ...

Today, the use of expensive household electrical appliances in your life plays a fundamental role in comfort and greatly facilitating the performance of various work. But how often do electrical appliances fail? What is the main reason for the cessation of their functioning and how to protect electrical appliances from premature failure?

Today, almost all imported equipment has units protecting the device from power surges, which burn out with a high voltage surge, but do not allow the device to completely fail.However, the electrical appliance must be taken to a repair shop to replace the fuses.

How to secure electrical appliances in your home or office?

Reason for switching to energy-saving LED products. Comparison and simple mathematical calculation of the savings and benefits of the purchase in the long run.

Today, many talk about new energy-saving technologies. That in the near future the traditional "Ilyich bulbs" will live out their Century and a new era is coming, or rather the electrical LED revolution.

This issue has risen to the state level. Starting with the President, who gave instructions to the state corporations Rosstekhnologii and Rusnano, to introduce energy-saving technologies, due to the fact that electricity is not used up efficiently and it is time to break stereotypes and keep up with the times. Factories will be built in a short time on the territory of Russia, where they will produce LED products ...

Comparison of a conventional ceiling LVO lamp with an LED analogue.

The revolutionary Age of lighting is approaching. The best universal technology for lighting equipment, selected at the state level, is energy-saving LED technology. And technological innovations appear, there are a huge number of them, they replace like ordinary incandescent lamps, spotlights, architectural and interior lighting. There are solutions for offices, and in general, for their upcoming construction, using cost-effective lighting devices.

Namely, where I drove everything, in the last sentence, these are LED lamps built into the ceiling. Let's see if there is a benefit in its use and how economical is this device?

This is a collection article that describes and uses the most common chemical power sources at present.

In the modern world, portable power supplies are indispensable. They are used in all digital, consumer electronics and not only.

The quality and duration of a particular appliance depends on the correct choice of the battery. Below are the types of current sources and a description of their advantages and disadvantages.

The life of this battery is about 90-3700 discharge-charge cycles. Electromotive force (EMF) - 1.3 Volts. Self-discharge is about ten percent per month. Application temperature: -10 to 40 ⁰FROM ...
