- the maintenance personnel 120 is no longer required to shut down part of the manufacturing floor, use equipment (e.g., a lift), or require multiple maintenance personnel 120. Rather, the maintenance personnel 120 may simply go to the power supply rack 110 on the ground level at location 130 to remove the failed power supply and replace it with a functioning power supply.
- the one or more power supplies 112, 114, 116 and 118 may be electrically connected to one or more LED light sources 102 and 104 located in locations 140 and 150, respectively, via electrical connections 122 and 124, respectively.
- the electrical connections 122 and 124 may be made via a electric cable or electric wire.
- the location 140 may be an indoor environment such as a manufacturing plant, a warehouse, a mine, and the like.
- the location 150 may be an outdoor environment such as a tower or an antennae located outside.
- the LED light sources 102 and 104 may include various electrical components that are not shown, for example, resistors, capacitors, printed circuit boards, optics, reflectors, LED chips or die, and the like.
- FIG. 1 illustrates each location 140 and 150 only having one LED light source 102 and 104, respectively, it should be noted that each location 140 and 150 may have any number of LED light sources.
- the one or more power supplies 112, 114, 116 and 118 may provide direct current (DC) to the one or more LED light sources 102 and 104.
- the power may be a low voltage DC.
- the power supply may provide less than 150 Watts (W) of power.
- the low voltage DC also provides a safer operating environment for the maintenance personnel 120.
- each one of the LED light sources 102 and 104 may be associated with one power supply, e.g., the power supply 112 for the LED light source 102 and the power supply 114 for the LED light source 104. As a result, each one of the LED light sources 102 and 104 may be
- a group of LED light sources may be powered by a single power supply 112, 114, 116 or 118.
- the one or more power supplies 112, 114, 116 and 118 are each located remotely from the LED light sources 102 and 104.
- the LED light sources 102 and 104 each have a housing 106 and 108, respectively, that completely encloses an LED die of the LED light sources 102 and 104.
- the one or more power supplies 112, 114, 116 and 118 are located external to the housing 106 and 108 of the LED light sources 102 and 104. This advantageously allows the power supply to be replaced without having to open the housing 106 and 108. Thus, possible damage to electronics of the LED light sources 102 and 104 inside of the housing 106 and 108, respectively, is minimized.
- the locations 140 and 150 are at different locations than the location 130.
- the one or more power supplies 112, 114, 116 and 118 are located at the same location 130 on the ground level.
- the LED light sources 102 and 104 are located in different remote locations at a level higher than or lower than the ground level.
- the LED light source 102 may be located above ground on a high warehouse ceiling of location 140 or below ground in a mine that is not easily accessible.
- the LED light source 104 may be located outdoors on a tower 152 hundreds of feet above ground level.
- the maintenance personnel 120 would be required to go out to the location 140 and 150 and use special equipment to replace the power supply.
- the maintenance personnel 120 may replace the power supplies (e.g., the power supplies 112 and 114) for the LED light sources 102 and 104 in a single power supply rack 110 at the location 130.
- a single maintenance personnel 120 may replace power supplies for two remotely located LED light sources 102 and 104 without having to leave the location 130.
- substantial costs savings may be achieved by reducing the number of needed maintenance personnel, costs associated with sending personnel out to locations 140 and 150 and using equipment needed to reach the LED light sources 102 and 104 that are at a level above the ground.
- Another advantage of having the one or more power supplies 112, 114, 116 and 118 remotely located from the LED light sources 102 and 104 is that the overall heat load is significantly reduced. In other words, the power supplies 112, 114, 116 and 118 will operate cooler due to being removed away from heat generated by the LED light sources 102 and 104 that directly affects the longevity of the power supplies 112, 114, 116 and 118. As a result, the life span of the LED light sources 102 and 104 is also increased. For example, the life span of the LED light sources 102 and 104 may be increased by 30%-50%.
- One possible drawback of having the one or more power supplies 112, 114, 116 and 118 remotely located form the LED light sources 102 and 104 is that there may be a loss of power over a distance of the electrical connections 122 and 124.
- the one or more power supplies 112, 114, 116 and 118 may be designed specifically for the LED light sources 102 and 104 such that there is no loss or minimal loss (e.g., less than 10% loss of power) along the distance of the electrical connections 122 and 124.
- the power supplies of the present disclosure are designed to power the LED light sources 102 and 104 at a same voltage as an LED light source having a co-located power supply.
- the remotely distributed power network for an LED lighting system 100 provides a more efficient way to operate LED light sources.
- the overall costs associated with maintaining and operating the LED light sources is significantly reduced.
