An LED board consists of a carrier material equipped with electronic elements and LEDs. In addition, there is a tinned copper surface for the solder connection. The shapes of the boards can be completely different. They can be a cluster, a strip, a ribbon or a square matrix.
Light-emitting diodes are attached to them. A distinction can be made between different types of circuit boards. There are flexible circuit boards, rigid circuit boards and aluminium core circuit boards, each of which have different advantages and disadvantages and are therefore used in different places.
A glass-fibre reinforced carrier made of epoxy is present in rigid PCBs. These boards are characterised by their rigidity and therefore cannot be bent. Their advantage is that they can therefore be processed well, as they stay well in the desired layers during processing. Their disadvantage, however, is that the length of each is limited.
In contrast to rigid blanks, flexible blanks are often made of a rather thin epoxy material. Their advantage is that they can be soldered together to form a very large unit. Aluminium core PCBs, as the name suggests, are mounted on a sturdy aluminium carrier. They are very heat efficient and are often used in high-power LEDs.
LED boards are not only differentiated by their shape and type, but also by their voltage. There are low-voltage variants such as an LED board 12 V or 24 V, but also high-voltage boards with 230 V. Which voltage is needed depends, of course, on the requirements and the use. The low-voltage boards run at half the current and are therefore best suited for use in rather damp rooms, such as bathrooms or kitchens. Due to the low voltage, they are less dangerous in these rooms and longer distances can be realised.
SMD LEDs are light-emitting diodes of the surface-mounted device type. This means that they are soldered directly onto the circuit boards and are thus smaller and flatter in design. This saves manufacturing and space costs. Their disadvantage, however, is that due to this smaller design and the smaller cross-section, they heat up too quickly at a usual current intensity.
In addition, mini LEDs have less cooling surface than normal LEDs, which can lead to increased heat damage and functional failures. This means that SMD LEDs need sufficient air circulation from outside and should be installed in rather cool rooms. Then nothing will stand in the way of their service life and performance. The use of SMD LEDs is advantageous and equally suitable for everyday use as well as in industry.
In contrast to wired components, electronic components manufactured with SMD have no wire connections - that is what is special about SMD manufacturing. There is a wide range of colours for SMD LEDs. Advertising signs - illuminated with warm white light to gaudy colour - can make the shopping experience exciting and eventful.
But coloured lighting effects can also add variety to decorations when installed in private spaces, while they are used as control lights in industrial settings.
