T-type LEDS

A T-type LED represents the conventional shape of an LED. However, its body doesn't have to be round by default. These LEDs are primarily used for signalling and for back-lit switches of electric appliances. Generally, the structure of an LED includes an LED chip, the bonding, gold or aluminium wire, and a plastic shell.

1)Wired LEDs

The Wired LED is at present still the most well-known LEDs because this design was alreadyused for a very long time in electronics. They were mostly used however only as control small lamps.

When the luminous efficiency of semiconductor crystals became better and better, the wired LEDs became generally accepted in the lighting industry. Several wired LED in summary, are found nowadays in LED SPOTS, LED tubes, LED modules and LED chains.

The advantage of wired LEDs exists in very favorable production in the small heat emission and that they can very simply soldered. The most usual models of wired LEDs are 3mm, 5mm and 10mm diameter.

The reflector tub in that semiconductor crystal is embedded, is also the short leg of a wired LED and also the MINUS -(cathode). A further distinguishing feature for the Minusseite of a Bedrahteten LED is an easy flattening of the plastic shroud on this side.

Wired LEDs are produced in all colors also in RGB (RED, GREEN, BLUE). Either with automatic color change or automatic dialable. The automatic dialcash possess 4 legs (pin).

Conceptual structure of a wired LED

The basis is made from a metallic lead frame with a specially treated surface. In order to achieve a directional light distribution of high efficacy, LED chips are mounted on a stamped reflector (cathode) using a conductive adhesive. The anode is contacted by a gold wire. The light distribution characteristics of an LED are determined by the geometry of the reflector, the shape of the plastic shell and the positioning of the chip inside the shell.

Superflux LEDs ( Spider LEDs )

One could see superflux LED (or Spider LED called) as advancement of the wired LED.

They possess a large reflected beam angle and send their light laminar and are therefore better suitable for surface lighting. The four contact contacts (pin) do not only make a better heat dissipation and thus a high life span possible, but they can be headed also separately. Spider LED contains up to 4 semiconductor crystals (chips).

These advantages make those for superflux LED a perfect multi-chip carrier with infinitely many ranges of application.

Superflux are used in LED bulbs, LED tubes, LED modules and ever more frequently in addition, in the autolighting industry

Here we know them as Soffitten in many different sizes and colors. In the advertising industry they are used e.g. for signature lighting or dia. assemblies.

Superflux LEDs are used for turn signals, stop light or daily headlight. SMD LEDs are produced in all colors also in RGB (RED, GREEN, BLUE).
