The cross-strait information industry and technical standards forum common standard "LED flat panel lamps for indoor general lighting" has been officially announced, and the contents of the standard are interpreted as follows: First, the scope of application This standard is applicable to indoor flat panel LED lighting fixtures with a power supply voltage not exceeding 250V. 1, indoor use This standard applies to general lighting LED panel luminaires used indoors (not for outdoor use). 2, general lighting This standard applies to general lighting and not to local lighting. General lighting refers to uniform lighting that is set to illuminate the entire site. Local lighting refers to the illumination used for a specific visual work to illuminate a part. 3, LED flat panel lamps LED flat panel luminaire (LED flat panel luminaire) refers to a thin-surface illuminating illuminator that uses LED as a light source to form a illuminating surface through a light guide plate and/or a diffusing member, including a control device, a heat sink, an optical component, and related components. The overall thickness does not exceed 70mm. LED flat panel lamps include side light guide LED flat panel lamps and direct illumination LED panel lamps. Side light guide LED panel light fixture: An LED light fixture, the LED mounted on the side of the light guide plate is transmitted to the entire surface of the light through the light guide plate. Direct illumination LED panel luminaire: An LED luminaire that illuminates the entire luminaire surface with direct light from the LED. LED flat panel luminaires can be mounted in an embedded, or surface mount, or suspended style. The luminous flux range of LED flat panel lamps is 600 lm to 5000 lm. 4, the power supply voltage does not exceed 250V Power supply voltage types can include both AC and DC. The AC mains voltage can include either 50 Hz or 60 Hz. This standard applies to LED panel luminaires with a supply voltage of 250V or less. Second, the general requirements LED flat panel luminaires should meet safety requirements and electromagnetic compatibility requirements. 1. Safety requirements Embedded LED panel luminaires shall comply with the requirements of GB 7000.202 "Lamps Part 2-2: Embedded Lamps for Special Requirements". Surface-mount or ceiling-mounted LED panel luminaires shall comply with the requirements of GB7000.201 "Lamps Part 2-1: Special Requirements Fixed General Luminaires". 2, electromagnetic compatibility requirements LED panel luminaires shall comply with GB 17743 "Limitations and Measurement Methods for Radio Disturbance Characteristics of Electrical Lighting and Similar Equipment", GB 17625.1 "Electromagnetic Compatibility Limits Harmonic Current Emission Limits (Device Input Current per Phase ≤ 16A)", GB 17625.2 "Electromagnetic compatibility limits for voltage variations, voltage fluctuations and flickering of devices with rated currents ≤ 16A and unconditionally connected in common low-voltage power supply systems" and GB/T 18595 "Electromagnetic compatibility of general lighting equipment" Requirements for Disturbance Requirements. Third, special requirements LED flat panel luminaires should meet the following special requirements. 1, electrical performance (1) Input power The measured input power should not exceed 110% of the rated input power. This subclause refers to the requirements of IEC/PAS 62722-2-1 "Specifications for luminaire performance Part 2-1: Special requirements for LED luminaires"7 and IEC/PAS 62717 "LED modules for general illumination - Performance requirements". LED is a kind of light source that is afraid of heat. If the power consumption is large, it will generate a large amount of heat. The heat can cause the luminous flux/light output to decrease, the heat can cause the life to decrease, and the heat can cause the wavelength to increase (the color shifts to red). . The guiding ideology of the qualification judgment is to limit the input power, which cannot be large and can only be small. The input power in the electrical performance is used in conjunction with the two test parameters of the luminous flux in the photometric performance. (2) Input current The measured input current should not deviate from the rated input current by more than 10%. (3) Power factor The measured power factor shall not be less than 0.9 and shall not be less than 0.05 of the rated power factor. (4) Voltage adaptability When operating within ±10% of the rated input voltage, the light output should be within ±5%. 2, photometric performance (1) Initial luminous flux The initial luminous flux should not be lower than 90% of the rated luminous flux. This subclause refers to IEC/PAS 62722-2-1 "Specifications for luminaire performance Part 2-1: Special requirements for LED luminaires" 8.1 and IEC/PAS 62717 "General LED modules for lighting - Performance requirements" 8.1. The guiding principle of the luminous flux qualification judgment cannot be low and can only be high. The luminous flux in photometric performance is used in conjunction with the two input parameters of the input power in electrical performance. (2) Luminous flux maintenance rate The 6000h luminous flux maintenance rate of the LED panel luminaire should not be lower than the luminous flux maintenance rate corresponding to the claimed luminous flux maintenance rate code. The three categories of luminous flux maintenance rate are shown in Table 1. When the manufacturer provides component reliability data, the test duration can be reduced from 6000h to 2000h. The effective reliability data should include at least the luminous flux maintenance data of not less than 6000h at three temperatures of the LED module: The lumen maintenance rate measured at 2000h should not be lower than the calculated luminous flux maintenance rate limit of 2000h. According to the luminous flux maintenance data provided by the manufacturer and the working temperature of the LED panel luminaire, the on-state 2000h luminous flux maintenance rate limit of the LED panel luminaire is calculated by the interpolation method. The operating temperature of the LED panel luminaire is lower than the minimum temperature of the 6000h luminous flux maintenance data provided by the manufacturer. The minimum temperature provided by the manufacturer is used to calculate the 2000h luminous flux maintenance rate limit. The operating temperature of the LED panel luminaire is higher than the maximum temperature of the 6000h luminous flux maintenance data provided by the manufacturer. The maintenance rate data provided by the manufacturer should not be used to calculate the 2000h luminous flux maintenance rate limit. This clause refers to IEC/PAS 62722-2-1 "Lighting Performance Part 2-1: Special Requirements for LED Lamps" 10.2 and IEC/PAS 62717 "General LED Modules for Lighting - Performance Requirements" 10.2. (3) Performance a) The measured initial LED panel luminaire performance should not be lower than 90% rated LED panel luminaire performance. This subclause refers to the requirements of IEC/PAS 62722-2-1 "Specifications for luminaire performance Part 2-1: Special requirements for LED luminaires" 8.3. Lamp efficacy and light efficiency are different concepts: 1 Luminous efficacy is the ratio of the luminous flux emitted by a light source to the electrical power it consumes, in lm/W. Luminaire efficacy is the ratio of the initial total luminous flux emitted by a luminaire to the power it consumes, in lm/W, under the claimed conditions of use of the luminaire. "Light effect" is used to evaluate LED light source. "Lighting performance" is used to evaluate LED lamps. LED light source efficacy and LED lamp efficiency all indicate the efficiency of converting electrical energy into light energy. It is an indicator to describe the energy-saving characteristics of lighting products, but its connotation It is different. The luminous flux of the light source in the light effect of the 2 LED light source refers to the luminous flux emitted by the bare light source (the state that has not been installed in the luminaire). The molecular luminous flux in the performance of an LED luminaire refers to the luminous flux emitted by the luminaire after the light source is installed in the luminaire and the power of the required LED control device or LED control device is used. The electric power consumed by the LED light source is not greater than the electric power consumed by the LED luminaire. 3 light source light efficiency is much greater than the efficacy of the lamp. First, because the LED enters the luminaire, the junction temperature increases, the light output decreases (heat loss); the second is because the light source enters the luminaire, and the system loss occurs after using the LED control device or its power supply; the third is that the light passes through the luminaire optical system. The loss after the luminaire efficiency (light loss). Lamp performance = light source efficiency × (1 - heat loss after entering the lamp) % × (1 - system loss) × (1 - light loss after entering the lamp) %. b) The measured initial LED panel luminaire performance shall meet the requirements of the corresponding level in Table 2.
