Nowadays, in many places of our lives, we apply LED lights. The existence of LED lights makes our lives more convenient and efficient. However, for consumers, the various products on the market make it difficult for us to make purchases. Don't worry now. Experts are here today to provide a specific introduction to the selection of LED lights, hoping to help everyone.
1. What kind of flame retardant PBT plastic shell should be chosen for the plastic shell of the entire lamp.
2. Brightness. The brightness of LED varies, and the price varies. The LED used for LED lighting fixtures should comply with the Class I laser rating standard.
3. Pay attention to observe whether there is any phenomenon of uneven thickness of the fluorescent powder coating affecting the normal lighting of the lamp tube after being powered on
4. Lifespan. The key to different qualities is lifespan, which is determined by light decay. Low light attenuation, long lifespan, long lifespan, and high price.
5. Chip size. The size of a chip is expressed by its side length, and the quality of a large chip LED is better than that of a small chip. The price is directly proportional to the size of the chip.
6. Glow. LEDs with different angles and purposes have different angles of illumination. Special luminous angle, high price. Such as full diffuse angle, the price is higher.
7. Antistatic ability. LED with strong anti-static ability has a long lifespan and is therefore expensive. Usually, LEDs with anti-static voltage greater than 700V can be used for LED lighting.
8. Leakage. Current LED is a unidirectional conductive luminous body. If there is reverse current, it is called leakage current. LEDs with high leakage current have short lifespan and low price.
9. Wavelength. LEDs with consistent wavelengths have consistent colors. If color consistency is required, the price will be higher. It is difficult for manufacturers without LED spectrographs to produce products with pure colors.
10. Chip. The light-emitting body of LED is a chip, and different chips have significant price differences. Chips from Japan and the United States are relatively expensive, while those from Taiwan and China are generally priced lower than those from Japan and the United States.
11. Some products have energy efficiency labels on their packaging. This indicates that the product meets safety specifications, reaches a certain level of light preparation, and has an average lifespan of over 8000 hours before being issued with an energy efficiency label.
12. Some LED light models have two lighting colors to choose from: white light and yellow light. Generally, people feel that white light is colder and yellow light is warmer psychologically. To compare the differences in colors, you can go to the showroom to appreciate them. Users can choose lighting colors that match their personal preferences with home furnishings.
13. Many consumers choose LED lights based on the power of tungsten filament bulbs they have always used as a reference. Most manufacturers will list on the packaging the power of the product itself and the power of tungsten filament bulbs with similar reference luminosity. For example, there is a "20W → 85W" mark on the packaging, which generally refers to the actual power of the lamp being 20W and claims to emit a luminosity similar to that of an 80W tungsten filament bulb.
14. When selecting LED lights, it is also necessary to consider the technical parameters of electronic ballasts, such as harmonic content, power factor, and whether filter components are installed. Especially in situations where large areas and batches of LED lights are used, it is necessary to choose LED lights with low harmonics, high power factor, and filtering devices, and try to install as many power switches as possible to avoid damage caused by the high-voltage pulse impact of the power grid when a large number of LED lights are turned on and off simultaneously.
15. Colloids. The colloid of ordinary LED is generally epoxy resin, and LED with anti UV and fireproof agents is more expensive. High quality outdoor LED lighting should be anti UV and fireproof. Each product has different designs that are suitable for different purposes. The reliability design of LED lighting includes factors such as electrical safety, fire safety, applicable environmental safety, mechanical safety, health and safety, and safe usage time. From the perspective of electrical safety, it should comply with relevant * * and national standards..
