As a common LED, straw hat LEDs are used in different scenarios. Here we talk about the advantages of straw hat lamp beads for LED digital tubes, but there are also some factors that need to be considered:

Advantages:
Higher brightness: LEDs usually have higher brightness and can provide clear and eye-catching display effects, which is very important for the display of LED digital tubes, and can be seen well even in strong light environments.

Low cost: Compared with some other types of LED light-emitting diodes, the price of LED straw hats is relatively cheap, which can reduce the cost of homemade LED digital tubes.
Easy to obtain and weld: Straw hat LEDs are common in the electronics market and easy to buy. And its pin structure is relatively simple, and the welding operation is relatively easy for people with a certain welding foundation.
Good heat dissipation: The appearance structure of the straw hat LED gives it relatively good heat dissipation performance. When used for a long time, it can better dissipate the heat generated, which helps to improve the stability and service life of the LED digital tube.
Disadvantages:
Large size: The volume of the straw hat LED is relatively large, which may limit the miniaturization design of the LED digital tube. If there are strict requirements on the size of the digital tube, straw hat lamp beads may not be suitable.
The light color consistency may be poor: There may be certain differences in light color, brightness, etc. between different batches of straw hat lamp beads, which may affect the overall display effect of the LED digital tube. When making it yourself, you need to screen and test the purchased straw hat lamp beads to ensure the consistency of light color and brightness.
Limited viewing angle: The light emitting angle of the straw hat LED is relatively narrow, which means that the display effect seen at different viewing angles may be different. If you need to clearly see the display content of the LED digital tube within a larger viewing angle range, you need to reasonably design the installation position and angle of the straw hat lamp beads.

In summary, straw hat LEDs for homemade LED digital tubes have their feasibility and advantages, but their applicability also needs to be comprehensively considered according to specific needs and application scenarios. If you have high requirements for display effects, size, and light color consistency, you may need to choose other types of LED light-emitting diodes.
