COB stands for Chips on Board.

This is a new technology in the packaging of LEDs for lighting purposes. Essentially, many LED chips are integrated together on a single, good thermal conductor substrate without separate encapsulation. When lit, it looks like a continuous light panel without visible individual light points.

The reason for the development of this technology is to ensure that LED light sources with increasingly higher efficiency have a longer lifespan. This is achieved by emitting light over a larger surface area, and since there is no individual encapsulation, the substrate can dissipate heat over a large area and directly. Ensuring a lower operating temperature is the clear key to longer-lasting LED operation.

From a user experience perspective, the advantage of COB LEDs over other LED light sources is that because the light is generated over a larger, continuous area, it is possible to create designs that do not cause glare and yet provide adequate illumination. A traditional LED (DIP LED, SuperFlux, or Power LED, SMD LED) as a point light source can be very glaring. To reduce the glare caused by the strong light point, these LEDs often use optical lenses or etched glass surfaces, which all reduce efficiency. Although for other reasons, such as design, COB LEDs can also use matte finishes, lenses, or etched surfaces, fundamentally, COB LEDs are the least glaring and provide the most uniform illumination among LEDs.

It is more practical to mention the types of LEDs in somewhat chronological order, so those who are immediately interested in SMD LEDs can find them at the bottom of the page.

DIP LED

The most well-known LED form, which is also the oldest type. Originally, it functioned as an indicator light for electronic devices. The industry considers the lifespan of these traditional (usually 3-5mm diameter) epoxy-housed LEDs to be the shortest. If this weren’t the case, as the oldest types, only these would exist, and new solutions wouldn’t have been developed. Of course, these DIP LEDs are also constantly being developed, and they are capable of emitting increasing luminous flux. Moreover, to ensure higher luminous flux, the so-called dual-chip DIP LED was created. This is practically two LEDs built into one, thus capable of emitting double the luminous flux from one spot. This encapsulation of multiple chips has proven to be a successful solution for other types as well. In this case, its peculiarity is that its size remains the same as if there were only one chip in the epoxy housing. Thus, theoretically, we can achieve double the luminous flux from the same spot, but this also comes with double heating, which raises doubts about the expected lifespan.

The industry considers DIP LEDs to have a short lifespan because the light and heat generated in a small area, due to their small size, result in poor heat dissipation, and the continuous oxidation of the epoxy housing, the lens, leads to a decrease in luminous flux. Against the problem of heat dissipation, it is argued that the excellent (in many cases perhaps the highest) efficiency of DIP LEDs results in very little heat generation. Even after prolonged illumination, DIP LEDs are touchable, just warm, not hot, and manufacturers haven’t even installed heat sinks on them. In contrast, the Power LEDs introduced below, and increasingly more powerful SMD LEDs generate so much heat that they are unusable without heat sinks, as they would quickly deteriorate. The advantage of DIP LEDs over other solutions is that practically any lighting angle LED can be manufactured within a 120-degree spatial angle without a separate lens or mirror structure. That is, the head end of the epoxy casing is shaped into a lens form, and the distance between the light source and the lens, as well as the curvature of the head end (i.e., lens), determines the lighting angle. Most commonly, DIP LEDs with lighting angles of 120, 90, 60, 38, 30, and 15 degrees are found.

We all experience how different colors evoke various moods in us. In color therapy, we harness the healing and stimulating effects of colors. The healing and mood-improving effects of colors are multiplied with the use of color therapy. It replenishes lost energy, improves memory and resilience, relieves stress, eases digestive issues, invigorates, refreshes, and rejuvenates. Color therapy creates harmony in our soul and can bring us peace.

Hollwich (1964), Tilgner (1967), and Dieckhuss (1974) studied the effects of colored radiation on human water balance, sugar metabolism, the diencephalon and pituitary system, blood composition, hormone metabolism, the autonomic nervous system, and liver metabolism. They proved that colored metals and colored environments also elicit experimentally verifiable reactions in living organisms. Thus, ultraviolet rays enhance performance, and the red color’s effect on increasing blood flow is also evident on skin areas not directly exposed to radiation. Various pathological phenomena caused by exposure to different colored environments have been described.

Colors, with their electromagnetic vibrations, continuously affect us throughout our lives, whether we are aware of it or not. A seaside vacation with the soothing proximity of the vast blue water relaxes and calms us. The green of vast forests soothes and balances us. Colors can be used in many ways for healing. We can linger on a painting, use carefully chosen colored tablecloths and curtains, or even paint the room in colors appropriate for the treatment. Selecting our clothes based on their color can address any issue. We can choose foods that match our mood and health from vegetables and fruits of appropriate colors. But we can also use colored light techniques. However, whatever method we choose, the goal is always to achieve harmony, so we should only use shades that do not conflict with our tastes and aesthetic sense, as we can only hope for healing and good cheer from these!

White light has different shades. The specific value of the “shade” of white light is characterized by Kelvin, or color temperature.

IP designations are encountered multiple times during the design of LED lighting. They are most commonly seen with LED drivers, LED strips, and are essential for outdoor or poolside applications.

IP ratings are determined based on practical tests. Their meaning can be determined from the table below.

Looking for beautiful and low-consumption floor lighting?

But don’t want to carve cavities into the floor afterward?

Here’s the solution!
The LED floor lighting is only 8 mm thick, so it can perfectly fit into laminate flooring up to 8mm thick.
Can be installed in both cold and warm flooring, suitable for interior and exterior use.
The light source can be popped out from its aluminum housing.
