LED Configuration:
Single Chip - The single chip design consists of a single ultra-bright LED of the latest LED technology, AlInGaP or InGaN, which is mounted
onto an incandescent base. Even though there is only one LED, this high intensity product can provide equivalent light output of the bulb it replaces.
This design has a slightly narrower viewing angle than either the multi-chip or cluster, yet is one of the most cost-effective designs available.
Cluster - The cluster uses multiple discrete SMD or 3 mm (T1) LEDs mounted into the appropriate incandescent base. The viewing angle of the
cluster is 120°, however the use of multiple LEDs increases the overall light output. The overall design provides flexibility where the latest in LED
technology, AlInGaP and InGaN, can be employed.
Multi-chip - The multi-chip device incorporates 6 LED die-mounted on a specially designed ceramic header which is then placed onto a tradi-
tional incandescent base. It's unique construction enables versatility; not only can the die be mounted on this header but additional components can
be added. Typical viewing angle of the multi-chip is 120°.
Polarity
LEDs are diodes which allow current to flow in only one direction. If you are unfamiliar with the polarity of your circuit, a rectifying circuit must
be used. Dialight's non-polarized based LEDs incorporate a full wave rectifier and all the necessary components to allow proper operation in any cir-
cuit providing the correct voltage is used.
Maximizing Light Output
Since lens caps act as filters for the light emitted from the based LED, it is important to match the emitting color of the LED. If not matched prop-
erly, the overall light output may be substantially reduced. Dialight recommends using transparent lenses which will
optimize the light output.
