FAQs
1, Are LED lights energy-saving?
LED lights convert most of the electrical energy into visible light, basically not into ultraviolet or infrared light; However, incandescent lamps only convert 5% of electrical energy into visible light and 95% into infrared, producing thermal effects; Fluorescent lamps convert most of the electrical energy into ultraviolet light, with less conversion into visible light. So, compared to LED lights, they are more energy-efficient.
2. What do the "SMD6050" and "SMD5050" data in the light source column of the product specification sheet refer to as "6050" and "5050"?
LED size: 0603, 0805, 1210, 5050 refers to the size (in English/metric) of the light-emitting element LED used on the LED strip.
0603: Converted to metric system, it is 1005, which means that the length of the LED component is 1.0mm and the width is 0.5mm. Industry abbreviation 1005.
0805: Converted to metric system, it is 2125, which means that the length of LED components is 2.0mm and the width is 1.25mm. The industry abbreviation is 2125.
1210: Converted to metric system, it is 3528, which means that the length of the LED component is 3.5mm and the width is 2.8mm. Industry abbreviation 3528.
5050: This is the metric nomenclature, which means that the length of LED components is 5.0mm and the width is 5.0mm. Industry abbreviation 5050
3. How many lights per meter are there for a light strip, and how many lights are cut into one unit?
Number of LED lights: 15 lights, 30 lights, and 60 lights refer to how many LED components are soldered per meter of length on the LED strip. Generally, the 1210 specification light strip has 60 LEDs per meter; The 5050 specification light strip has 30 LED strips per meter, 48 LED strips per meter, and in special circumstances, some have 60 LED strips per meter; The 3528 (low power, single 0.06W) specification light strip has 30 to 60 LEDs per meter. However, due to the disguised price reduction, the brightness has been lowered and the number of lights per meter has also increased. Cutting unit: 12V light strips can be cut for every three lights; The 24V light strip can be cut for every six lights. The cutting area is usually marked with a "scissors" pattern or the gap between two sets of positive and negative pole markings. Can only be cut at the marked position. Cutting incorrectly or off center will result in one meter not shining!
4. Waterproof classification of light strips.
According to the waterproof level requirements, it can be divided into: non waterproof LED light strips, drip waterproof LED soft light strips (waterproof level IP55), semi sleeve waterproof LED soft light strips (waterproof level IP65), and full sleeve waterproof LED soft light strips (waterproof level IP68). The full sleeve is further divided into simple full sleeve embedded LED light strips for waterproofing, silicone injected LED light strips for waterproofing, and injection glue waterproofing effect is significantly better than simple full sleeve waterproof light strips.
According to the adhesive materials used for waterproofing, they are further divided into epoxy resin adhesive and silicone. In terms of appearance and luminous effect. The waterproof light strip infused with silicone emits a higher intensity of light, providing a comfortable touch while also considering the concept of environmental protection. But he has a drawback of poor flexibility and fragility. Compared to others, most people still choose epoxy resin adhesive, which has good flexibility and relatively low cost, so it is widely used.
Note: The last two digits of IPXX are XX, and the first X represents dust prevention, ranging from 0 to 6, with a maximum level of 6; The second digit X represents waterproofing, ranging from 0 to 8, with the highest level being 8. (IP is the abbreviation for Ingress Protection). So, IP68 is the highest waterproof level standard for connectors.
5. The width of the light strip？
There are four types of LED light strips according to their width: 6mm/8mm/10mm/12mm, etc. The 3528 general board width is 8mm, and the 5050 general board width is 10mm.
6. How to fix and install the light strip?
Each LED strip has a self-adhesive 3M double-sided adhesive tape on the back. When installing, you can directly peel off the sticker on the surface of the 3M double-sided adhesive tape, then fix the light strip in the place where it needs to be installed and press it flat by hand; Or the product comes with a transparent card.
How to choose the power supply for LED light strips?
LED strip power supply: Since the power supply is not included when purchasing LED strips, after calculating the required length of the LED strip, the power supply needs to be calculated and matched with the power supply. The power of different LED strips varies, so it is important to carefully choose the matching power supply. Here is a list of the power of LED light strips:
3528LED strip: 12V, 30 LEDs per meter, power 2.4W per meter
3528LED strip: 12V, 60 LEDs per meter, power 4.8W per meter
5050LED strip: 12V, 30 LEDs per meter, 7.2W power per meter
5050LED strip: 12V, 60 LEDs per meter, 14.4W power per meter
For example, if a 5050LED light strip is purchased and matched with a 12V, 4A specification power supply, then one power supply can only carry a 6-meter 5050LED light strip. Because the power per meter of the 5050LED strip is 7.2W, a total of 43.2W for 6 meters, and the rated power of the power supply is 48W, it is generally not recommended to use the power supply at full load because it has a significant impact on the lifespan of the power supply. It is recommended to only use 95% of the power supply. If 100 meters are required, a minimum of 16 4A power supplies are required.
