Interpretation of ERP Directive Design Requirements for LED Drivers

1. Overview of ERP Energy Efficiency Directives and Implementation Measures (1194/2012)

On October 21, 2009, the European Union promulgated the Framework for Ecodesign Requirements for Energy-Related Products (2009 /125 /EC) to replace the old 2005/32 /EC Directive, thereby extending the product range from energy-consuming products (EUP: Energy - using products) Expanded to all energy-related products (ERP), the new version is referred to as the ERP directive.

The 1194/2012/EC Directive and its Regulations contain:

Like the LVD and EMC directives, the ERP directive is also included in the EU CE system. Therefore, the products involved in the relevant implementation measures must be considered before the export to Europe, and the CE mark must be attached. The following sections will focus on the interpretation of the eco-design requirements for directional lighting, LED lights and related equipment in Regulation 4 - 1194/2012/EC. (c) From the third stage, the standby power consumption of the control unit of the luminaire shall not exceed 0.5W.

2. Design requirements for LED lighting control devices (drive power supplies) in the ERP directive

2.1 Time period of the implementation rules

Each eco-design requirement should be applied according to the following phases: Phase 1: September 1, 2013 Phase II: September 1, 2014 Phase III: September 1, 2016.

2.2 Energy efficiency requirements for luminaire control devices

(a) From the second stage, the no-load power consumption of the luminaire control unit shall not exceed 1.0W. "No-load mode" refers to the environment of the luminaire control unit. In this environment, the input of the luminaire control unit is connected to the supply voltage, but its output is disconnected from all main loads, and this disconnect is a normal operation. (b) From the third stage, the no-load power consumption limit should be 0.5W. For the luminaire control device, if the output power (P) exceeds 250W, the control device's no-load power consumption limit should be multiplied by P/250W.

"Standby mode" is one of the modes of the control device of the luminaire, which is turned off by a control signal during normal operating conditions. This mode is for control devices with built-in switch function and is permanently connected to the supply voltage during normal use.

2.3 LED lamp (built-in LED drive power ) power factor requirements

Since the first phase:

P ≤ 2 W: no requirement

W < P ≤ 5 W: PF > 0.4

5W < P ≤ 25 W: PF > 0.5

P > 25 W: PF > 0.9

2.4 LED lamps (built-in LED driver power supply) startup time requirements

Starting from the first phase, the start-up time needs to be less than 0.5 seconds. "Light start time": The time it takes for the luminaire to start fully and keep the light on after the power supply voltage is turned on. See the following illustration for details: T1 is the startup time. But the startup time also includes the response time of the LED module.

T1: start-up time; T2: time from the heat engine to 95% of the luminous flux output;

3, Infineon electronic LED driver power supply provides detailed solutions for ERP directive requirements

Infineon Electronics introduces a range of programmable constant power adjustable power supplies (from 40W to 600W) with integrated DALI dimming interface, 0-10V/PWM/Timer dimming interface, dimming can be turned off, external over temperature Protection and other functions.

Its main features are: wide output current/voltage range, and PF greater than 0.9 and THD less than 20% in efficient working areas. The blue box inside is the efficient working area of ​​the constant power adjustable product.

After the dimming is turned off, the front-end control circuit is turned off by the single-chip microcomputer control, so that the standby power consumption is reduced to less than 0.5W. Infineon Electronics' various intelligent programmable power supplies (40W, 60W, 75W, 96W, 150W, 200W, 240W, 320W, 600W) can meet the power factor, startup time and standby of ERP for LED driver power supply design requirements. Power consumption requirements. And through design optimization and multiple verification, the new generation of programmable power supplies is also superior in reliability, achieving a design life of 75,000 hours at 75 degrees Celsius.

4. Overview

This paper explains in detail the various indicators of the European Eco-Design Directive ERP latest implementation measures 1194/2012/EC and the design performance related to LED drive power. As a mandatory standard for products to be included in the CE system, the ERP directive covers various eco-design indicators. Infineon Electronics has also developed a number of programmable power supplies based on this directive, fully complying with the power factor required by the ERP directive, start-up time, standby Time and other requirements.
