Compared with the two concepts of LED power and life, the concept of efficiency is relatively complicated. There are three general efficiencies, and there are five concepts that are usually confused. In addition, there are six concepts in light conversion efficiency generated by the structure of the lamp, which can be divided into five categories in total. As follows, LED corrugated lamp manufacturers give four categories:

       For a single lamp bead, there are two concepts of efficiency: 1. The luminous efficiency of the lamp bead, that is, how much light can be emitted for each input of 1W of electric energy. This efficiency is a measure of the luminous efficiency of a single lamp bead, not the whole The indicator of the luminous efficiency of the lamp, so the luminous efficiency of a single lamp bead is only the basis for determining the luminous efficiency of the whole lamp, not equal to the luminous efficiency of the whole lamp; 2. The conversion efficiency of the lamp bead refers to how much electric energy is used for every 1W of electric energy input. Come to shine. The luminous efficiency is generally used more, and the conversion efficiency is usually used to evaluate the development level of the chip.

   In addition, the efficiency of the drive may be familiar to many people, that is, the ratio of the input drive power to the drive output power is the drive conversion efficiency.

       The efficiency of the lamp beads in the application environment is generally not used, but it is generally used to evaluate the quality of a batch of lamp beads, that is, without considering the drive, the power consumed by the lamp beads directly on the lamp panel and the light emission of the lamp panel The ratio of the total. The lumen wattage calculated in this way can reflect the average luminous efficiency of a batch of lamp beads, so as to determine the quality of a batch of lamp beads.

       One is the focus of everyone's concern, that is, the luminous efficiency of the entire lamp. This formula is very simple, it is the ratio of the total amount of light emitted by the lamp to the total input power. The light conversion efficiency generated by the lamp structure may be special. The light conversion rate of the lamp structure = the total amount of light emitted by the entire lamp/the total amount of light emitted by the lamp panel, which is defined as: the light emitted on the lamp panel and the back The ratio of the light emitted by the whole lamp, at least one of which is worse than the light attenuation of the light-expanding plate or the light-transmitting plate.

       The light environment is people's psychological feeling of light in a certain visual space. A good light environment gives people a good visual experience, and this good visual experience directly affects people's physical and mental health. People should consider the issue of energy saving while considering creating a good light environment. The concept of green lighting is how to reduce the amount of mercury released and how to save the limited energy that humans can survive.
