Introduction

In order to standardize the energy efficiency measurement and detection work of projectors that implement energy efficiency label management, according to JJF 1261.1- In accordance with the requirements of the.2017 "Measurement and Inspection Rules for Energy Efficiency of Energy-Using Products", this specification is formulated. This specification is published for the first time. Projector Energy Efficiency Measurement and Inspection Rules

1 Scope

This standard specifies the liquid crystal display with projection as the main function and high-pressure mercury lamp or metal halide lamp as the light source. (LCD) and digital optical processing (DLP) projector energy efficiency measurement requirements, testing conditions, testing items and Methods, test result evaluation criteria and test reports. This specification also applies to solid-state light source projectors with energy efficiency labels and liquid crystal-on-silicon (LCOS)-based displays. device projector. This specification does not apply to integrated projection units composed of projection screens and projectors and professional projection units for theater projections. video camera. This specification is applicable to the supervision and inspection of energy efficiency measurement of projectors, and entrusted inspections can be carried out with reference to this specification. production and Units that sell projector products can also refer to this specification for testing. The projectors to be tested should be products that have passed the self-inspection by the producer, or products that have been imported and sold by the seller.

2 References

This specification references the following documents.
