Precautions for LED daylight lights
1. Installation: LED comes with constant current source, no ballast or starter is needed.
2. Voltage: AC 85V--AC 245V, all can work normally.
3. Heat dissipation: prevent dust from covering the radiator and affect heat dissipation.
4. Waterproof: Because the LED daylight tube is composed of upper and lower parts: there is a gap at the connection, it is recommended to add a protective cover.
5. Vibration: LED daylight lights have strong anti-vibration ability. As long as it is not violently impacted, it generally does not cause damage.
Teach you how to choose LED daylight lights:
LED daylight lights are very professional, and most people can't tell them apart. The following 5 tricks tell you that you can choose LED lights without instruments.
1. Look at the packaging and labels
The national mandatory product LED lighting manufacturers mark the following on the package: rated voltage range, rated power, rated frequency. In general, print high-quality products with good quality, clear handwriting, not easy to fall off, wipe with a soft damp cloth, the logo is clear and recognizable, the manufacturer's trademark and related certification marks.
2. Look at the appearance of the LED light
Real LED daylight light. From the light point of view, the shape and size of the light are better and more consistent, the product consistency is better, and quality assurance is easier. Of course, the appearance must not have cracks, looseness between interfaces. The led light must choose the kind of engineering plastic flame retardant plastic PC shell. Ordinary plastic deformation and flammable, the aluminum tube must be bright, aviation aluminum.
3. Working temperature
When the LED daylight light is in normal operation, the temperature should be low. Otherwise, the life of the LED light is very short. At the same time, fast flickering or very harsh fluctuations when the energy-saving lights are lit, indicating that the energy-saving lights have quality problems. After a few minutes of power on, there should be a temperature, which proves that the heat dissipation is good, and the aluminum substrate is used to dissipate heat. There is no temperature, it is a glass fiber board, and the heat cannot be dissipated.
4. Look at the startup performance
The startup of LED daylight lights has a characteristic: it will light up immediately when it is powered on, and will not flicker.
5. Weigh the weight, compare the weight with each other, the heavier is better than the lighter, and the heavier indicates that the material is used well.
