Alternatively, one or more of the outlet cores is another type of outlet compatible with another IEC standard or compatible with a standard from another standards organization.
FIG. 17 illustrates how any of the module outlets described herein can be lighted to indicate outlet electrical status or lighted for any other purpose. A module outlet includes a printed circuit board 110. Mounted on printed circuit board 110 are circuits 111, circuits 112 and circuits 113. Each of circuits 111, circuits 112 and circuits 113 include light emitting diodes (LEDs) or another type of light source.
Each of circuits 111, 112 and 113 can include LEDs with different colors so that the color of a lighted LED indicates status of an associated outlet. For example, color of light can indicate whether or not power is available from the outlet, whether or not current being drawn from the outlet is within a normal range, working status of a device powered by the outlet or a warning condition such as an overload condition, a low voltage condition, a high voltage condition. Other status conditions can be communicated based on a particular need or configuration.
Housing 120 can consist of separate module housing 127, module housing 128 and module housing 129. For example, module housing 127, module housing 128 and module housing 129 have solid color outer walls that serve as a light barrier so that light information from each module is prevented from interfering with light information from other modules. For example, housing 120 is composed of plastic, metal, rubber or another solid color material suitable to make module housing. For example, each of module housing 127, module housing 128 and module housing 129 are a different color than the other module housings. Alternatively, housing 120 can be composed of transparent or clear material. Alternative to separate module housing, housing 120 can be integrated in a single piece of material.
An outlet core body 121, an outlet core body 122 and an outlet core body 123 are each made from clear or transparent material that serves as a light pipe from LEDs on circuits 111, 112 and 113. For example, each of outlet core body 121, outlet core body 122 and outlet core body 123 is made from transparent material of a different color.
Alternatively, each of outlet core body 121, outlet core body 122 and outlet core body 123 is made of clear material so that LEDs on circuit 111 control the appearance of color on outlet core body 121, LEDs on circuit 112 control the appearance of color on outlet core body 122 and LEDs on circuit 112 control the appearance of color on outlet core body 121. Clear material is particularly useful when circuits 111, 112 and 113 include LEDs with different colors where that the color of a lighted LED indicates status of an associated outlet. In this case, the clear material of outlet core body 121, outlet core body 122 and outlet core body 123 serve as light pipes providing color status information to a user or potential user of the outlet. For example, outlet core body 121, outlet core body 122 and outlet core body 123 are composed of plastic, glass or another clear or transparent material suitable to make an outlet core body.
An outlet plug 131, an outlet plug 132 and an outlet plug 133 are each shown ready to be plugged into an outlet of module outlet 109. A portion 134 of outlet plug 131 is made from clear or transparent material so that when outlet plug 131 is plugged in, light information originating from LEDs on circuit 111 and traveling through outlet core body 121 remains visible through the clear or transparent material of portion 134 of outlet plug 131 even when outlet plug 131 is plugged into an outlet of module outlet 109.
Likewise, a portion 135 of outlet plug 132 is made from clear or transparent material so that when outlet plug 132 is plugged in, light information originating from LEDs on circuit 112 and traveling through outlet core body 122 remains visible through the clear or transparent material of portion 135 of outlet plug 132 even when outlet plug 132 is plugged into an outlet of module outlet 109. A portion 136 of outlet plug 133 is made from clear or transparent material so that when outlet plug 133 is plugged in, light information originating from LEDs on circuit 113 and traveling through outlet core body 123 remains visible through the clear or transparent material of portion 136 of outlet plug 133 even when outlet plug 133 is plugged into an outlet of module outlet 109. For example, portion 134 of outlet plug 131, portion 135 of outlet plug 132, portion 136 of outlet plug 133 are composed of plastic, glass or another clear or transparent material suitable to make a portion of an outlet plug.
In the example shown in FIG. 17, module outlet 109 has three outlets. This is only exemplary as a lighted module outlet can also have one outlet, two outlets, four outlets, or any number of outlets depending on a desired configuration.
FIG. 18 shows outlet plug 131, outlet plug 132 and outlet plug 133 each plugged into an outlet of module outlet 109. Light information originating from LEDs on circuit 111 and traveling through outlet core body 121 remains visible through the clear or transparent material of portion 134 of outlet plug 131. Likewise, light information originating from LEDs on circuit 112 and traveling through outlet core body 122 remains visible through the clear or transparent material of portion 135 of outlet plug 132. Light information originating from LEDs on circuit 113 and traveling through outlet core body 123 remains visible through the clear or transparent material of portion 136 of outlet plug 133.
