In terms of color, LED lights have “colorful”, “white”, “warm white”, “red”, “green”, “yellow”, “blue” and so on. Theoretically, LEDs can tune out many colors,
But there are only a few mainstream ones, and there will be some “deviations” depending on the color temperature.For example, “warm white” is divided into 2000K and 4000K color temperature, “white
“Colour” includes cool white, “true white” which is close to the color of sunlight, etc. According to our company’s shipment statistics, the largest shipment is “warm white”, followed by “white”, and then “white”.
Yellow, blue. There are very few other colors.Choose “warm white” if you want “warmth”; choose “cool white” if you want “shine”;
Choose “blue”, choose “yellow or green” if you want “alternative sense”
2. Model
The commonly used models of LED strips are 3528 and 5050.
Therefore, whether you can buy a good chip depends on the integrity of the manufacturer, in addition to whether you can pay a good price when you buy it yourself. Generally speaking, chips from Europe, America and Japan are better than chips from Taiwan, and chips from Taiwan are better than domestic chips. But the price is also higher than one. Sometimes I am really “proud”: There is really no shortage of cutting-edge talents in China. Once any product arrives in China, not only the performance of the product will be “decreased”, but the price will also drop.
Therefore, when you choose, you may wish to choose some mid-priced products. It won’t be great, but it won’t be bad either. The bid is very low, the quality is really “nothing to say”, and the bid is high, and you can’t buy American chips because the market share is small and manufacturers will not produce them. I believe you will not spend a high price to buy a product that only “50%” may use American chips, right?
The SMD5050 used in the light strip is packaged with Taiwan’s high-brightness chip, and the luminous flux is 1-2lm higher than that of ordinary chips. A 5050 lamp bead has three chips. When one chip is damaged, it will not affect the light emission of the other two chips. When only three cores are damaged, only a group of three 5050s will not light up, which will not affect the entire light strip.
structure
The owner personally summed up the structural comparison of the light strips, and users can choose casing or glue-based ones according to their own preferences.The owner recommends casing construction
material
In terms of materials, there are two types, one is hard light strips, and the other is soft light strips made of flexible materials.
LED hard light strips are assembled with PCB hard boards. LEDs can be assembled with SMD LEDs or with in-line LEDs, depending on the needs.
Instead, different components are used.The advantage of the rigid light bar is that it is easier to fix, and it is more convenient to process and install; the disadvantage is that it cannot be bent at will, and it is not suitable for irregular lights.
place.SMD LEDs for hard light strips have many specifications such as 18 LEDs, 24 LEDs, 30 LEDs, 36 LEDs, and 40 LEDs;
18, 24, 36, 48 and other different specifications, there are front and side, and the side light is also called the Great Wall light bar.
The flexible LED light strip uses FPC as the assembly circuit board and SMD LED for assembly, so that the thickness of the product is only the thickness of a coin and does not take up space;
Common specifications include 18 LEDs, 24 LEDs in 30cm length, 15 LEDs, 24 LEDs, 30 LEDs in 50cm length, etc.There are also 60cm, 80cm, etc., which are different
The users have different specifications. And it can be cut or extended at will without affecting the luminescence. The FPC material is soft and can be bent, folded,
Coiled, it can move and stretch freely in three-dimensional space without breaking.It is suitable for use in irregular places and places with small spaces, and because it can be bent arbitrarily
Curved and coiled, suitable for arbitrarily combining various patterns in advertising decorations. 1. Silicone material is colorless and highly transparent.
2. Good flexibility, can be folded and bent at will, good tear resistance, not hard.
3. Low viscosity, good defoaming property, smooth and bright surface after hardening, no yellowing.
4. Good performance under high and low temperature conditions (-50°C+260°C).
5. Strong adhesion, good insulation and sealing, waterproof, corrosion resistance, excellent weather resistance and UV resistance.
Number of lamp beads
The number of lamp beads usually refers to how many lamp beads are contained in a one-meter light strip. The common ones are 15, 30, 45, 60, 72, and 120; because 5050 is relatively large, you can’t find 5050 light strips with 120 beads. Similarly, it is difficult for you to find 3528 with 15 beads, because there are too few . The whole light strip doesn’t make much sense anymore.
Note: 3528, 5050 according to the type of lamp bead; the packaging form is divided into bare board, epoxy, semi-large epoxy, potting, and sealing; the color is divided into colorful, white, warm white, red, green,
Blue, yellow; the number of lamp beads is divided into 15, 30, 60, 72, 112, 120 and so on. Due to the large number of combinations, coupled with frequent changes in material prices. So, not all specifications of products are in stock.
Based on this fact, the bare boards or casings with pure white, warm white, and less than 60 beads can basically be shipped on the same day.Some unconventional products will be produced according to
