1. LED lamp bead chips, domestic chips are not as good as imported ones. The cheap ones on Taobao are all made in China and will break down every few months of use. Our regular products are Taiwanese original wafers (brightness 110LM/W) and American Bridgelux chips (brightness 140LM/W), with a 3-year warranty. Simple test method: destroy the lamp beads and use an electron microscope (which can be purchased for a few hundred yuan) to look at the chip pattern inside. In addition, you can also use a light meter to test the lamp beads when the conditions such as current and voltage are the same. brightness.
2. LED lamp power supply. A good power supply has good heat dissipation. The IC used is imported and has automatic protection function, making the LED lamp have a longer life.
3. LED lighting color. Good quality light has uniform color and no color difference. For example, warm white has the same color temperature, but different light colors are not uniform. For example, although the 10 lights are all warm white, they look different and have color differences. Some are more yellow, and some are light yellow or even red. In addition, if a good LED has a high color rendering index, the object will retain its original color when the light shines on it. A poor LED will cause the object to change color when the light hits it. Simple test method: a batch of lights are lit at the same time, and the naked eye can see whether there is any color difference.
4. LED lamps have a long service life. Good quality ones have a long service life, but low-end ones will break down soon.
5. LED lamps have light attenuation. Light attenuation means that the brightness of the light will gradually dim over time. The light of good LEDs decays slowly, but the light of poor LEDs decays quickly. It will become obviously dark after a few months of lighting. At present, some manufacturers will use overload current to brighten the lamp beads in order to recharge them as inferior ones. In this way, although the brightness is about the same as or even brighter than a good LED at the beginning, the light decay of the lamp beads will be very serious and they will die very quickly. Simple test method : Keep it on for a week, then use a light meter to test the brightness and compare it with the initial brightness.
1. LED ceiling spotlights: generally 1W, 3W, 5W for home decoration. The light color is white light or warm white. Ceiling spotlights focus light, mainly for decorative effect. Home decoration is used for TV background walls, entrances, etc. When buying a baby, buyers should make sure that the opening size of the baby is consistent.
2. LED downlights: generally 3W, 5W, 7W for home decoration. The light color is white light or warm white. Downlights are used for astigmatism and lighting, and are often used in living rooms, corridors, etc. When buying a baby, buyers should make sure that the opening size of the baby is consistent.
LED advantages
3. LED light strips: According to the size of the LED lamp beads, they are divided into LED light strips 3528. LED light strips 5050. 3528 is the small lamp bead and 5050 is the large lamp bead. . LED 5050 light strips are usually called super bright, 3 times as bright as 3528.
What we recommend is 1 meter 60 beads.
4.LED lamps: Conventional household lamps are divided into T5 and T8. The length is 1500px, 2250px, 120 cm. The wattage is 8-15W. The power can be customized. The quotation is for the complete set (including installation bracket).
Advantages of LED compared to traditional energy-saving lamps
1. Save 70% of electricity, such as 10W energy-saving lamps and 3W LED lamps.
2. Long life, 5 times that of traditional energy-saving lamps. 3. Stable light color, no radiation and flicker, best protecting eyesight.
