LED downlights are widely used in everyday lighting due to their energy-saving features. Minimum energy consumption and maximum light output to achieve high luminaire performance is the main goal of product design, and it is the key technical parameter to characterize the energy saving of the product. Evaluate the consistency between the power and light output of the product and the actual power consumption and actual light output, and at the same time study the impact on the actual lamp performance. It helps people pay attention to the accuracy of parameter identification, guides enterprises to accurately claim the energy consumption index of products, and enables users to understand the real technical parameters of lamps. This paper analyzes the qualification level of power and light output parameters of a group of LED downlights through several eligibility evaluation criteria, and gives the current qualified rate of power and light output related to key technical parameters of energy utilization, and reminds us Accurately marking the power and light output consumed by LED luminaires to meet future higher evaluation criteria.
Energy has a particularly important strategic position in the national economy. In the context of China's society focusing on energy conservation and emission reduction, LED lamps are widely used in daily lighting for their energy-saving features. However, there is currently no national performance standard for evaluating the key parameters such as power and luminous flux, which leads to a mixed market, which causes great trouble for consumers when purchasing energy-saving products. Various local groups are also drafting LED lighting product standards. However, there are no systematic LED lighting performance requirements in international and domestic countries. The evaluation methods for key technical parameters of LED lighting products, such as power, luminous flux and lighting efficiency, are also varied. In this paper, the measurement data of 276 LED downlights are used to analyze the current quality of LED downlights affecting the main energy-saving indicators of LED downlights, such as power, luminous flux and luminaire performance. At the same time, the international and domestic popular evaluation methods are compared and evaluated. Find reasonable judgment principles and provide strong technical support for the development of performance standards.
First, the current quality analysis of LED downlights
At present, manufacturers generally mark power and luminous flux in the marking of the luminaire, and the luminaire performance index has not been marked in the mark. This article focuses on power, luminous flux and luminaire performance indicators to clarify the quality of LED luminaire products on the market.
In this paper, 46 batches of 276 LED downlights were selected as the analysis samples, and the power coverage ranged from 3.3W to 35W; the diameter ranged from 3cm to 19cm. The technical parameters of the power, luminous flux, and luminaire performance of the 276 downlights were measured.
