26 watt LED lamp brightness can top 200 watt incandescent lamp

The evening of October 21, 1879, Edison and his aides were put into carbon filament light bulbs, which invented the light bulb.

November 4, 2011, the national development and Reform Commission and other departments announced by the size of the gradual elimination of incandescent light road map, the ancient lights will gradually out of people's vision.

Incandescent beyond the rising star: fluorescent lamps and LED energy-saving lamps

It has been more than a century since the incandescent lamp was used by the human race. However, this kind of lamp can only convert 10% of the energy into light, and the other is converted into useless heat energy by 90%.

When the incandescent lamp is working, the temperature of the bulb can be up to 100 DEG C. This low efficiency cost a lot of energy, in November 4th, the NDRC and other departments announced by the power of phasing out incandescent roadmap, and decided since October 1, 2012, banning the import and sale of more than 100 watt incandescent lamps for general lighting.

Shenyang Huaguang Lighting Electrical Appliance Co., Ltd. Engineer Liu Changxin introduction, the reason for the elimination of incandescent lamps, because there are more energy-efficient lamps.

The fluorescent lamp is the incandescent lamp after the second generation light source, which uses gas discharge, the gas inside the power will emit light, the efficiency is greatly improved compared with the incandescent lamp, close to 40% efficiency, the heat generated by the same brightness of the incandescent lamp is only 1/6. Therefore, in many places, especially in the summer market, will not produce too much heat, but also save electricity. "

In the inspection room, there is a lamp is a metal base, half of the bulb is wrapped in metal, and the other half is a milky white shade.

Liu Changxin said: This is the LED energy-saving lamps, is currently the most advanced light source. When an electric current passes through a wire to the chip, the electrons emit energy in the form of a photon, which is the principle of LED emission. In theory, the efficiency of LED energy saving lamp can reach 100%, but in the present process, the efficiency of electric energy into light energy in more than 45%. "

The same is 40 Watt LED energy saving lamp luminous flux is about 5 times of incandescent lamp

In Shenyang Huaguang Lighting Electrical Appliance Co., Ltd., Liu Changxin in accordance with the program, the incandescent lamp, fluorescent lamp and LED energy-saving lamps were tested and compared.

The device is composed of three parts, the integration of the ball diameter of two meters, sensors and computer spectrum analysis system.

Open the integral ball, put the lamp in the goal, and then turn off the ball. There is a white barium sulfate coating on the inner surface of the integral ball, which can reflect the light to the sensor in the sealed space.

Will be the same as 40 watt incandescent lamp, fluorescent lamp and LED energy saving lamp flux contrast.

Incandescent lamp: 367 lumens. Fluorescent lamp: 2721 lumens. LED energy saving lamp: 3498 lumens.

Liu Changxin introduction: "in general terms, the luminous flux is the amount of light emitted per unit of time, the unit is called lumen, 100 lumens equivalent to the light emitted by 15 watt incandescent lamp. "

As can be seen from the test, in the case of the same power of 40 watts, fluorescent lamps and LED energy saving lamps to light much more than incandescent lamps, LED energy saving lamp luminous flux is nearly 5 times the incandescent lamp.

Incandescent lamp life is about 1000 hours, LED energy saving lamp life in between 50 thousand hours to 60 thousand hours

In the computer analysis system, the luminous flux is located in 2600 lumens, in accordance with the data analysis, to issue these lights, the need for incandescent power of 200 watts, fluorescent lamp power of 40 watts, LED energy-saving lamp power of 26 watts.

Liu Changxin introduction, the size of the power of the lamp represents the number of energy consumption. Consume 1 kwh of electricity, the lamp can be lit for 5 hours, the light of the 40 Watt can be used for about 25 hours, and the LED energy saving lamp can be used for nearly 40 hours.

Under the same conditions, to emit the same amount of light, incandescent energy consumption is 5 times the fluorescent lamp, LED energy saving lamp is about 8 times, which means that the latter two will save considerable energy.

In order to confirm this data, in the dark background, Liu Changxin 25 watt incandescent lamp, a fluorescent lamp of 7 watts and a 5 Watt LED energy-saving lamp series.

Comparison shows that the three issued roughly the same amount of light, 5 Watt LED energy-saving lamps to be slightly brighter than the 7 WATT fluorescent.

In addition to the differences in energy consumption, there is a great difference in the life of the three.

Incandescent lamp life of 1000 hours or so, fluorescent lamp life is generally between 6000 to 10 thousand hours, LED energy saving lamp life in between 50 thousand hours to 60 thousand hours.

In order to use 6 hours per day, incandescent lamps can be used for more than 5 months, fluorescent lamps can be used for nearly 3 years, LED energy-saving lamps can be used for about 23 years.

The old light bulb costs electricity but can be adapted to a wide range of voltages

Li Kai introduction, LED energy-saving lamps although efficient, but because of its high cost, so it can not be a large number of promotion.

The same can be issued 2600 lumens of light, the market price of 200 watt incandescent lamp is $2, while the price of 40 Watt fluorescent lamps in the $4, while the price of 26 watts of energy-saving lamps at around $200.

Although there are differences in the cost of electricity savings and longer service life, the cost of fluorescent lamps is the highest, the price of LED energy-saving lamps or expensive.

Li Kai introduction, from an environmental point of view, the use of incandescent lamp will produce waste heat, there are heavy metals such as tungsten. There is mercury in the fluorescent lamp, which can pollute the soil and rivers. LED energy saving lamp green environmental protection, no lead, mercury and other heavy metals, no pollution to the environment.
