The role of tri-color energy-saving lamps The difference between tri-color energy-saving lamps and ordinary lamps
The tri-color energy-saving lamp is a kind of preheating discharge lamp. It can be seen from the three-color that it is composed of three primary colors of lamps. Perhaps many people do not know this kind of lamps very well. What is the function of the three-primary energy-saving lamps? What? What are the differences between tri-color energy-saving lamps and ordinary lamps? Let’s take a look at BENWEI LIGHTING.
Three primary color energy-saving lamps
The role of three primary color energy-saving lamps:
Three-color energy-saving lamps, full name three-color energy-saving fluorescent lamps, are a kind of preheating cathode gas discharge lamp, divided into straight tube shape, single U shape, double U shape, 2D shape and H shape. Take the H-shaped energy-saving fluorescent lamp as an example. It is composed of two glass tubes (the inner wall of the tube is coated with rare earth three-primary phosphors), a three-helical filament (cathode) and a lamp cap. Its working principle is similar to that of ordinary fluorescent lamps. It can be equipped with an inductive ballast (with a starter) or an electronic ballast (without a starter).
Warm light
The color temperature of warm color light is below 3300K. Warm color light is similar to incandescent lamps and has more red light components, which can give people a warm, healthy and comfortable feeling. It is suitable for homes, residences, dormitories, hotels and other places or places with low temperature.
Cool white light
Also called neutral color, its color temperature is between 3300K~5300K. Neutral color makes people feel happy, comfortable and peaceful due to the soft light. It is suitable for shops, hospitals, offices, restaurants, restaurants, waiting rooms and other places.
Cool light
Also called daylight color, its color temperature is above 5300K, the light source is close to natural light, it has a bright feeling and makes people concentrate. It is suitable for offices, conference rooms, classrooms, drawing rooms, design rooms, library reading rooms, exhibition windows and other places.
It is a difficult problem to balance the color rendering performance and the efficiency of the lamp. In Japan, the first fluorescent lamp to achieve this was a tri-primary fluorescent lamp with a color temperature of 5000K.
The three-primary-color fluorescent lamp improves the efficiency of the lamp through the green light, plus the blue and red light, and appropriately balances the three color lights, thereby successfully obtaining a new type of fluorescent lamp with high light efficiency and high color rendering performance.
Further changing the mixing ratio of these three kinds of lights, resulting in a three-primary fluorescent lamp (2700~3000K) with a warm light effect similar to a bulb; a three-primary fluorescent lamp with a spring neutral white light (4000~5000K); Yes Refreshing and bright daylight color three-primary fluorescent lamp (6200~6700K).
Three primary color energy-saving lamps
The difference between tri-color energy-saving lamps and ordinary lamps:
The main difference between tri-color energy-saving lamps and ordinary energy-saving lamps is the phosphor. Tri-color fluorescent lamps use rare earth phosphors with higher luminous efficiency.
The phenomenon of material luminescence can be roughly divided into two categories: one is when the material is heated to produce thermal radiation and emit light; the other is when the object is excited to absorb energy and transitions to an excited state (unstable state) in the process of returning to the ground state. Energy is emitted in the form of light. Most of the luminescent materials that use rare earth compounds as a matrix and rare earth elements as activators belong to the latter category, that is, rare earth phosphors. Rare-earth element atoms have abundant electronic energy levels, because the existence of 4f orbitals in the electronic configuration of rare-earth element atoms creates conditions for a variety of energy level transitions to obtain a variety of luminescence properties.
The tri-color energy-saving lamp is a typical hot cathode fluorescent lamp. It is an energy-saving lamp made by coating the inner wall of the glass tube with tri-color phosphors (mixed with red, green, and blue rare earth phosphors in a certain proportion). The phosphor emits light under the excitation of ultraviolet rays. Its luminous efficiency is more than twice higher than that of incandescent lamps. Generally, the luminous flux is above 55lm/W, especially its color rendering is greater than Ra78. The luminous flux maintenance rate in 100 hours is above 90%, and the luminous flux maintenance rate in 2000 hours is about 80%. The attention of all countries in the world.
When the lamp is energized, it discharges between the tungsten wire electrodes encapsulated at both ends of the lamp and emits ultraviolet rays. The phosphor converts short-wave radiation (ultraviolet rays) into visible light and emits light. The rare earth trichromatic fluorescent lamp, which contains rare earth phosphors of yttrium, europium and terbium, can emit brighter light and is closer to the solar spectrum than ordinary fluorescent lamps. Compared with ordinary fluorescent lamps, it can save 50% of energy consumption by achieving the same illumination. The powder is a mixture of three types of phosphors that emit narrow-band red (611nm), green (545nm) and blue (450nm) spectra.
