文档介绍：ENERGY STAR Program Requirements
for Traffic Signals
Eligibility Criteria
Below is the product specification (Version ) for ENERGY STAR qualified traffic signals. A product
must meet all of the identified criteria if it is to be qualified as ENERGY STAR by its manufacturer.
This traffic signal specification is based on a low energy requirement and conformance to the Institute for
Transportation Engineers (ITE) “Interim LED Purchase Specification, Vehicle Traffic Control Signal Heads,
Part 2: Light Emitting Diode (LED) Vehicle Traffic Signal Modules”(VTCSH Part 2). At this time, only the
LED technology meets such requirements and therefore the specification includes terms specific to LED
traffic signals. However, EPA is open to any other (non-LED) technology that meets both the EPA
specification and ITE’s VTCSH Part 1 or Part 2 requirements, or a future relevant ITE specification.
Manufacturers are encouraged to contact EPA with such technology only if they are able to meet such
requirements.
1) Definitions: Below is a brief description of an LED traffic signal and related terms as relevant to
ENERGY STAR.
A. Vehicular Traffic Signal: A power-operated illuminated traffic control device, other than a barricade
warning light or a steady illuminated lamp, by which traffic is warned or directed to take some specif
