Analysis of Lighting Standard Terminology

As a new energy-saving lighting product, lighting has many standard terms for lighting, but lighting terms are all used in professional documents. Today we will analyze lighting terms so that more people can understand lighting products. 1. Standard terminology of lighting—luminaire efficiency. Indoor lighting rarely uses light source alone. Usually the light source is used in the lighting fixture. After the light source is placed in the lamp, the light output of the lamp is lower than the light output of the single light source. The ratio is called the lamp efficiency. The high efficiency of lighting lamps indicates that the manufacturing quality of the lamps is good, and the energy-saving indicators of the lamps are high. The efficiency of the lamps is an important index to measure the quality of the lamps. By comparing the efficiency of the lamps, the quality of the lamps can also be indirectly evaluated. The relationship between the luminous efficiency of the lighting source, the efficiency of the luminaire, and the illuminance value of the luminaire is that the luminous flux output by the luminaire is only proportional to the efficiency of the luminaire, and the illuminance value of the luminaire is directly proportional to the luminous efficiency of the light source. The light distribution curve is related. The high illuminance value of the lighting does not mean that the luminous flux is high. If the light source with high luminous efficiency is placed in a low-efficiency luminaire, the output of the luminaire will be greatly reduced. The higher the luminous efficiency of the light source and the efficiency of the luminaire, the higher the lighting energy-saving index The higher the luminous efficiency of the light source and the efficiency of lamps and lanterns are important indicators to measure high-quality lighting products. 2. Lighting standard terminology-stroboscopic flash source stroboscopic is a phenomenon in which the brightness of the light source changes with time. When working under a stroboscopic light source for a long time, it will cause visual fatigue. The maximum stroboscopic time of the light source is 0.02 Seconds, and the visual dwell time of the human eye is 0.04 seconds. The stroboscopic time of the light source is faster than the visual dwell time of the human eye, so the human vision can hardly feel the light source flickering, but the visual cell of the human eye will sense it, which is the cause of visual fatigue. The higher the frequency of the light source flickering, the lower the visual fatigue caused by the stroboscopic. We call it low-frequency flicker. The stroboscopic will unknowingly affect human eye health and affect the quality of lighting. The stroboscopic of incandescent lamps, fluorescent lamps, and energy-saving lamps is determined by the working principle of the light source. It cannot be overcome and can only be reduced. The stroboscopic of the lighting source is generated by the driving circuit of the light source. Improving the driving method can achieve no stroboscopic. Commonly used lighting source strobes include: incandescent lamps (high frequency flashes), fluorescent lamps (electronic ballasts for low frequency flashes, inductive ballasts for high frequency flashes), energy-saving lamps (medium flashes), and some LED desk lamps have no standard Stroboscopic, in fact, is only a low frequency flash. Fluorescent lights must have stroboscopic, and AC-powered LED lights may have stroboscopic. Only battery-powered and not pulse-driven LED lights can be truly flicker-free. The high-quality LED light source has very low flicker. 3. Lighting standard terminology-the safety of lighting equipment The safety of lighting equipment includes electric shock, leakage, high temperature burns, explosion problems, reliability of installation and fixation, safety signs, application environment signs, etc. 4. Standard terminology of lighting-energy-saving indicators of lighting equipment The highest level of lighting lighting is visual beauty. In order to enjoy this beauty, the lights will be turned on for a long time to appreciate. If the power consumption of the lighting source is too high, users will be incurred due to electricity bills. Psychological burden causes a decline in visual aesthetics, thereby indirectly reducing the quality of lighting. Therefore, we also include the energy-saving indicators of lighting equipment in the lighting quality indicators.
