At the end of the year, the house is going to be renovated. I will teach you how to choose LED lamps.

1, LED lamp bead chips, domestic chips are not as imported. The cheap ones on Taobao are made in China, and they will be bad every few months. Our conventional ones are Taiwan original wafers (brightness 110LM/W) and American Puri chips (brightness 140LM/W), with a warranty of 3 years. Simple test method: by destroying the lamp bead, use an electron microscope (a few hundred pieces to buy it) to see the inside of the chip grain map, and also in the case of determining the same current, voltage and other conditions, using a illuminometer to test the lamp bead brightness.

2, LED lamp power supply, good power supply heat dissipation, the IC used is imported, with automatic protection function, making LED lamp life longer.
3, LED lighting color. Good quality light color uniform, no color difference. For example, warm white is a color temperature, but the poor light color is not uniform. For example, although the 10 lights are warm white, they look different, with color difference, some yellow, some are yellowish or even red. In addition, a good LED has a high color rendering index. The light is on the object, and the object is still the original color. The poor LED will cause the object to be discolored by the light. Simple test method: A batch of lights is lit at the same time, and there is no color difference with the naked eye.
4, LED lamp life, good quality and long life, low-end can not be used for a long time will be bad.
5, LED lamps light decay, light decay means that the brightness of the lamp will slowly dim over time. Good LED light decays slowly, and the poor LED light decays quickly. It is obviously dark after a few months. At present, some manufacturers will make the lamp be brighter by overloading the current in order to shoddy, so that although the brightness and the good LED are just the same or even brighter, the light decay of the lamp will be very serious, and it will die very quickly. : Always wait a week, then use the illuminometer to test the brightness, and compare it with the brightness at the beginning.
1. LED ceiling spotlight: home decoration is generally 1W, 3W, 5W. The color of the light is white light, warm white. Ceiling spotlights are concentrated, mainly for decorative effects. Home improvement is used for TV background wall, porch and so on. When the buyer buys the baby, it is necessary to determine whether the baby's opening size is in conformity.
2. LED downlight : home decoration is generally 3W, 5W, 7W. The color of the light is white light and warm white. Downlights are used for astigmatism and lighting, and are often used in living rooms, corridors, etc. When the buyer buys the baby, it is necessary to determine whether the baby's opening size is in conformity.
3. LED light strip: according to the size of the LED light bulb is divided into LED light strip 3528. LED light strip 5050. 3528 is a small lamp bead, 5050 is a big lamp bead. Usually the LED 5050 strip is super bright, which is 3 times the brightness of 3528.
4. LED tube: regular household is divided into T5, T8. The length is 1500px, 2250px, 120 cm. The wattage is 8-15W, the power can be customized, and the quotation is the whole set of quotation (including the mounting bracket).
The advantage of LED compared with traditional energy-saving lamps; 1. Power saving 70%, such as energy-saving lamps 10W, LED lights 3W. 2. Long life, 5 times of traditional energy-saving lamps, 3 light color stability, no radiation stroboscopic, most protective vision.
