A street light, lamppost, street lamp, light standard, or lamp standard is a raised source of light above a road, which is turned on or lit at night.
Variations (not currently tagged)
The suspending is commonly done by placing the lamp on top of a pole at the edge of a road or between lanes. Lamps may be mounted on the middle of a roadside power pole instead of a dedicated pole, although the latter may support low voltage power lines (power=minor_line) for electricity supply for the lamps. Another common scheme is to have the poles hold up a suspended carrying wire from which the lamp(s) hang.
In cities, the existing buildings sometimes replace the poles in either scheme. Occasionally, street lamps are attached to other structures of convenient height, such as bridges or road signs.
The mechanism and procedures for turning off and on street lamps vary a lot. Common schemes include turning them on/off at fixed times using a clock, turning them on/off a fixed interval from sunset/sunrise using a more complex clock, turning them on based on a light sensor (which tends to also turn them on in some weather conditions) and turning them off again late at night when there is less traffic. Some schemes also involve only turning on every second street lamp some of the time.
Add the node where the light source is actually positioned (i.e. next to the way lit).
- ref=* If the street lamps carry numbers intended to help identifying points on the road. For instance, in some places you could call the police and say that there has been a major car-crash on Big Street, southbound at light pole 35, and the police will know precisely where that is. This should not be used where the lamps carry numbers or identifiers used only for non-navigational purposes, such as reporting broken light bulbs or issuing permissions to hang posters from certain lampposts.
- lamp_ref_swd=* Düsseldorf city only tag for lamp numbers that are not used for navigation, see below.
- lit=* for tagging that a highway has some class of illumination.
- Proposed features/lamp - more flexible tagging of lamps, including street lamps
- Key:operator: "If the vast majority of a certain object in an area is operated by a certain organization and only very few by others then it may be sufficient to only tag the exceptions."
Currently there is a project to map all gaslighted streets and all gaslight lanterns in the town of Düsseldorf. See: Düsseldorf/Projekte/Gaslaternen
- lit_by_gaslight=yes This street is lit by gaslight.
- lit_by_gaslight=no This street is not lit by gaslight.
Special tagging used in Düsseldorf for gas lamps
(Many of these tags may also be applicable to electrical lamps, though no general scheme has been defined)
- highway=street_lamp Just as other streetlamps
- lamp_type=gaslight Show that the energy comes from gas.
- lamp_operator=Stadtwerke Düsseldorf All streetlamps in Düsseldorf are operated by this organisation.
- lamp_ref_swd=* The number on the lamp mast, given by the operator (SWD).
- lamp_model:de=* In Düsseldorf there are 5 different types of gas lamps in use.
- lamp_flames=* Number of flames in a lamp. There are four, six, eight or nine flames in a gas latern.
- lamp_mount=* Is the lamp mounted on a mast or on a wall?
- Lightness map, uses tile overlay rendering of lit=* and highway=street_lamp (page and tiles are not updated anymore).
