The difference and characteristics of piranha module, straw hat module and LED patch module

The main difference between the piranha module, the straw hat module and the LED patch module is brightness and light decay.

The straw hat module does not have a high piranha module in brightness. The main reason is that the straw hat module is not as heat-dissipating as the piranha module. Because the former is 2 feet, the latter can slightly increase the current a little.

The LED SMD module has a great improvement in brightness and light decay compared to the straw hat module and the piranha module. The 5050 patch has several chips built in, so the brightness is far more than the 3528 SMD module!

1. Different types of lamp beads are formed by the cutting of the epitaxial wafer and the form of the chip package, so that different module names are available;

2. Piranha, SMD3528 SMD module, SMD5050 SMD module and the previously popular straw hat mermaid, but a simple concept description of the appearance of the lamp bead; for example, the piranha lamp bead, simply because it is packaged The rear lamp bead looks a bit like a piranha; the patch 3528, 5050 is because the size of the lamp bead is 35*25, 50*50.

Essential difference:

1. Illumination angle: piranhas have flat heads, F3, F5, F7, etc. Different illumination angles can be selected according to actual needs. The most common ones are flat head (180 degrees) and F3 (120 degrees), which may have a wide luminous area and save Material; 3528 and 5050 light angles are more than 120 degrees, the brightness is relatively high, and the scope of use is also wide;

2. Brightness and light decay: The patch series has higher brightness than the piranha and straw hat series; especially the 5050 is packaged in 3 crystal 20MA or single crystal 60MA, far exceeding the 3528, piranha and straw hat series; the heat dissipation of the patch is better, so the light The decline is small.

3. Purchase price:

The brightness is high, and the light decay is of course more expensive. The patch series is the industry-leading trend! The light source is different. The so-called patch module uses a patch-type light source, which has high brightness, long life, slow light decay and high price. The piranha module uses a piranha light source, and the brightness is slightly lower than the patch. Light decays faster and the price is low.
