【 Building materials network 】At the home of Ms. Wang in Hexi, Nanjing Ceiling lamp It's broken. I found it when I was going to replace it. Home door The big supermarket is no longer pin sell energy saving light Ring of Lamp tube Instead, various LEDs Light bulb: 。 Ms. Wang wants to inquire about which is better, energy-saving lamp or LED lamp?

LED lamp has "occupied" the market

The reporter then went to the lamp counter of this large supermarket near Ms. Wang's home, only to see a more striking position on the shelf, where all the LED light bulbs were placed. At the lower part of the shelf, the reporter found several spiral energy-saving light tubes, and also did not see the circular energy-saving light tubes required by Ms. Wang. Then the reporter logged into the online flagship stores of several lamp brands and found that the stores sold ceiling lamps Downlight , or Desk lamp , are all LED lights, even the bulbs are all LED lights.

The reporter asked the customer service whether there were annular tubes of energy-saving lamps for sale in the store. The customer service clearly said that they were no longer sold.

LED lamp is more energy-saving and safer

The reporter found that a brand of LED light marked 4W on the outer package is equivalent to energy-saving light 6W Incandescent lamp 27W and 6W LED lamps are equivalent to 9W energy-saving lamps and 42W incandescent lamps. Are LED lamps really more energy-saving? Shi Chaoyang, deputy director of the National Quality Inspection Center for Semiconductor Lighting Products, said in an interview that the energy saving of LED lights mainly depends on the initial light efficiency. The greater the initial light efficiency, the more energy saving. From the test results, the initial luminous efficiency of LED lamps is significantly higher than that of incandescent lamps and energy-saving lamps, which is indeed more energy-saving. In addition to being more energy-saving, LED lamps are safer than incandescent lamps and energy-saving lamps. This is because the power consumption of a single LED is very low, the requirements for conductive lines are not high, and short circuit faults caused by line aging are rare.

LED lamps are less replaceable than energy-saving lamps

It is safer, more energy-saving, and has a short starting time, without electromagnetic noise... Although LED lights have obvious advantages, they have a small disadvantage in terms of replacement. The reporter found that many ceiling lights are also LED lights, but LED light source They are usually made together with lamps and cannot be replaced. This also means that if the LED ceiling lamp "strikes", you can only buy lamps again. If you use the ceiling lamp of the energy-saving lamp tube, you only need to replace the lamp tube.

What should I pay attention to when purchasing LED lights?

Household color temperature should not exceed 5000K

What precautions do consumers have when choosing LED lighting products?

Shi Chaoyang suggested that consumers should pay attention to the color temperature when purchasing brand products, in addition to purchasing through formal channels. If it is used in the bedroom, warm color can be selected, and the color temperature is about 3000K; Although the lighting in the living room should be bright, the light is good and soft, and the color temperature can be about 4000K; Corridor balcony For example, you can select products of about 5000K. For home use, the color temperature should not exceed 5000K, otherwise the light will be dazzling and not suitable for home use.

In addition, consumers should also be reminded that products with a very low price usually have a short service life, so they must be careful when choosing them.
