When men and women visit the supermarket to acquire a light bulb, the incandescent lamp, energy-saving lamps, LED lamps, in the long run what kind of lamp lighting impact is very good?

Experiment: incandescent lamp

I purchased three of the widespread lamps available to perform a contrast experiment. These three lamps are incandescent, energy-saving lamps and LED lamps, the selling price from 3 yuan to 49.8 yuan assortment. The incandescent lamp power rating of forty Watt, energy-saving lamp nominal power for 8 W, its nominal equivalent to forty watt incandescent lamp brightness, as well as the rated energy in the LED lamp for five watts, the nominal brightness is rather to your forty watt incandescent lamp within a dark room, the the three lamp are respectively linked on the base of 220 volts, present meter to measure latest, using the genuine power of the measurement of light by way of the check current and soon obtained the authentic power of the 3 lights. Incandescent lamp recent of about 40, the measured electrical power of about 0.18 watts; power conserving lamp latest is about 0.035, the measured energy of about seven.7 watts; LED lamp is about 0.021, the measured power of about four.six watts. From these information, the incandescent lamp measured electrical power may be the highest, but additionally essentially the most energy LED lights

So, the real lighting in the 3 sorts of lights and how? Experiments show that although the nominal electrical power on the LED lamp is only five watts, its brightness could be the highest. Incandescent lamp brightness is slightly decrease, the distribution of yellow light appears incredibly vivid, but the feeling is comparatively soft. Energy-saving lamp tube form to form, the light-emitting location greater, but the colour is white, search a bit harsh conclusion: LED lamp value highest.

Single from your value viewpoint, to buy a LED lamp is equivalent on the invest in of 16 incandescent; to purchase a energy-saving lamps, it truly is equivalent towards the cost of 9 incandescent lamps. Purchase LED lights are plainly not as very good as energy-saving lamps and incandescent light. But the energy consumption as well as lamp’s support life as well as other aspects, the LED lamp lighting for 15000 hrs, equivalent to 15 incandescent or three energy-saving lamps and. While in the electrical power consumption and incandescent lamps need to have to eat 600 kwh of electrical power, energy-saving lamps to 115.5 degrees, and LED lights is only 69 degrees calculated according to 0.48 yuan per kWh of electrical power, with 15000 hrs, the incandescent lamp is made use of to create electrical energy for 333 yuan, energy-saving lamps for $139.44, and LED lights only for $82.92. If long-term use, or LED light bulbs essentially the most cost-effective, as well as greatest lighting effect.
