How we choose when we buy LED hurdle lamp

1. From the control mode: it is divided into internal control mode (there is a single-chip microcomputer inside, and the color changes automatically when power is turned on) and external control mode (an external controller is required to change color).

2. In terms of change methods: divided into fixed color, seven-color, and full-color; fixed-color is used to outline, full-color can be used to outline, and can also be formed into a tube screen to display text, video, etc.;

3. In terms of size: there are D50mm and D30mm, this is the diameter; the length is basically 1 meter (can be customized); this needs to be selected according to actual needs.

4. From the perspective of internal controllability: there are 1 meter 3 sections, 1 meter 6 sections, 1 meter 8 sections, 1 meter 12 sections, 1 meter 16 sections, 1 meter 32 sections. That is to say, there are several segments in a 1-meter tube that can be independently controlled; the more segments of 1 meter, the better the effect of making videos. If the density is low, or to do some chasing effects, it is enough to do 1 meter 6 sections.

5. In terms of the number of LEDs, there are 96 lights for 1 meter, 108 lights for 1 meter, and 144 lights for 1 meter; the more lights, the better the effect. Generally, 144 lights per meter are used for full-color.

6. In terms of power supply, it is divided into high-voltage power supply (direct 220V power supply) and low-voltage power supply (12v power supply, 220v power supply needs to be converted by switching power supply); generally choose low-voltage power supply, which is more reliable and stable, and high-voltage power supply is easy to burn.

7. Divide by pixel

16-segment light tube per meter means that a 1-meter light tube has 16 pixels.

Generally, there are 6-segment digital tubes, 8-segment digital tubes, 12-segment digital tubes, 16-segment digital tubes, 32-segment digital tubes, etc. There are more 16-segment digital tubes. For example, 6-segment digital tubes are generally used in contour items.

8. LED guardrail tubes can be made in rich colors, and there is also a single color that is always bright, and the commonly used single color is red. Yellow. Blue. Green. White. Warm White!

Operating Voltage

Internal control 3-segment and internal control 6-segment working voltage: AC 24 and AC24V;

The 6-stage working voltage of external control is: DC24V (Note: Generally, DC is more stable for external control, because it is seen that it is driven by AC24V);

External control 8, 12, 16 working voltage: DC12V;

The 32-segment working voltage of external control is: DC5V;

degree of protection

IP67 (Waterproof and dustproof can withstand water immersion for a short time)

Dimensions

The D shape is divided into:

Divided into internal control and external control:

Internal control refers to the built-in controller, which can make some relatively simple change effects, and the voltage can be low voltage or high voltage.

External control refers to the external controller. Using the external controller can make more dynamic effects. It should be noted that the use of external control to control the effect of the guardrail tube must use a low-voltage power supply.

Waterproof Notice

The LED guardrail tube is generally sealed with hot melt adhesive or silicone at the interface of the outer cover, and the internal LED and circuit board are exposed. Due to the large temperature difference between day and night, the end of the outer cover expands and contracts differently from the outer cover, resulting in hot melt adhesive or silicone. There is a gap in the seal, and rainwater seeps into the inside after it rains, causing a short circuit and burning the LED. To solve this problem, the internal circuit and LED must be filled with glue. It is simple to seal the joints with hot melt adhesive or silicone, but the reliability cannot meet the requirements of large-scale outdoor applications. The other is the connector problem of the electrical connection. Many manufacturers often choose plastic joints for cheap, or choose poor quality metal joints. After a short period of testing and use, the plastic has not deformed, and there is no problem with waterproofing. It will be deformed, which will lead to the failure of the waterproof rubber ring, and the rainwater will seep into the joint and cause a short circuit of the electrical appliance. Especially in the charged state, the corrosion of the wire is several orders of magnitude higher than that in the uncharged state. The price of inferior metal joints is many times worse than that of qualified products.
