Abstract
An explosion-proof industrial signaling device. The explosion-proof industrial signaling device having an explosion-proof housing and a single module with the capability of emitting different colored lights to indicate the operating condition of a machine. The emitted light can be steady or flashing, and controlled by an external PLC or an onboard microprocessor. The PLC or microprocessor interprets incoming information and causes the color of the light or its flashing pattern to change accordingly. The light source maybe an LED.
Claims20
An explosion-proof industrial signaling device comprising:
- a housing;
- a single lens module mounted to said housing;
- and
- at least one light source contained within said module, wherein said light source includes a plurality of light clusters said clusters are disposed spaced apart from one another, each of said clusters containing lights of different colors which can be independently activated such that a signal is seen to be emitting from a signal housing as an individual color.
A method for processing visual indicator signals of an explosion-proof industrial signaling device is provided comprising the steps of:
- utilizing incoming analog information to enable a light emitting diode cluster to illuminate;
- decoding one programmable logic control input to illuminate one light emitting diode cluster of the same color;
- and
- decoding at least two programmable logic control inputs to illuminate at least two light emitting diode clusters of differing colors.
An explosion-proof industrial signaling device comprising:
- a single module means for protecting a light source, whereby said light source includes a plurality of clusters of lights, said clusters which are disposed spaced apart from one another in layers, each of said clusters containing lights of different colors which can be independently activated such that a signal is seen to be emitting from a signal housing as an individual color, and a plurality of light sources disposed in a spaced apart arrangement and located at a focal point of said single module means of said signal housing.
