Brightness of 5mm LED or dome lens SMD LED

There are different viewing angle in 5mm LED, 3mm LED, 8mm LED or 10mm LED. During the production, we will control the viewing angle by putting the LED frame deep into the mould of epoxy lens. We will get wider viewing angle when we make the LED frame more close to the top of LED lens. The common angle can be 15 dgeree, 30 degree, 45 degree, 60 degree and 90 degree. If we need to get wider viewing angle then that, we can use the 5mm straw hat shape of size to arrange the production;

5050 SMD LED with Milky Lens

5050 SMD LED with a diffused lens is a type of LED that uses surface-mount technology (SMT) to mount the LED chips onto a circuit board. The 5050 refers to the size of the SMD LED chip, which is 5.0mm x 5.0mm. The SMD package allows for a compact design and easy installation. The diffused lens or milky lens on the LED helps to evenly distribute the light emitted from the LED chip. This creates a softer, more uniform light output compared to a clear lens LED, which can produce harsher, more directional light. On the other hand, there also have three positio

Can Through-hole LED or SMD LEDs be Multiple Colors?

Color of LED depends on LED wavelength. From 365nm LED to 1550nm LED. There is purple, blue, green, yellow, red, deep red, IR LED color in the range. Each chip emits their own color and there will just have one color in one chip. Normally we will just package one chip into one SMD LED or through-hole LED package. For some project, there have won't have that much space for many LED and people have to need kinds of color in that space at the same time. Obviously, those LED that just got one single color canno

Can Domed Lens SMD LED replace Through-hole LED?

Through-hole LED is the first LED to be invented and it's composed of LED chip, LED frame gold wire and epoxy. During the production, the first step is donging the chip on the LED frame and connect them with gole wire. And then we need to put this LED frame in the epoxy mould so that DIP LED can get a epoxy lens, which can protect the LED chip from the impact and keep the gold wire inside the epoxy. On the other hand, because of the epoxy lens, the brightness of LED lamps will got increase. It's kind of convex lens on the LED chips.
