Talking about the Application of Energy-saving Light Source in Integrated Ceiling Lighting Module

In the traditional kitchen and ceiling decoration, most household consumers are basically light-weight decorative lights. That is to say, high illumination is taken into consideration, and the decorative effect is often overlooked. In general, most of the illumination light sources used are ordinary fluorescent lamps or incandescent lamps as illumination light sources, and most of them are based on honest ceiling lamps or lamp tubes. It really can't talk about fashionable personal kitchen and bathroom life.

The invention of the integrated ceiling product has broken this traditional kitchen and bathroom ceiling decoration stalemate. In addition to integrating the stylish personality of the ceiling itself, it is even more important that the functions of the lighting, heating, and ventilation modules are greatly enhanced, and the appearance is also highly valued in terms of ornamentation, which truly achieves a perfect fusion of function and decoration.

In this chapter, we will talk specifically about some of the technical parameters of integrated ceiling lighting sources and the relevance of these technical parameters to life:

What are the common technical parameters for lighting sources?

Color Rendering Index

The performance of the light source to visualize the color of the illuminated object is called color rendering and the color rendering index Ra is used to indicate the color rendering of the light source. The higher the color rendering index, the closer the color of the object under the light and the color under natural light; the lower the color rendering index, the more distorted the color of the object under the light.

â–  Color temperature

Color temperature represents the amount of light source color. When the color of the light emitted by the light source is the same as the color of the radiation of the black body at a certain temperature, the temperature of the black body is referred to as the color temperature of the light source, that is, the color temperature. When a standard blackbody is heated, its color is dark red, light red, orange, white, and blue as the temperature increases. The higher the color temperature, the more bluish the light color; the lower the color temperature, the more reddish the light color. The light color of the sun changes with time. The light color is yellowish at 40 minutes after sunrise, and the color temperature is about 3000K. At this time, the light appears warm and romantic. At noon, the sunlight is white and the color temperature rises to around 4800K-5800K. Light color reproducibility is good, cloudy color temperature around 6500K at midday, warm and balanced, there is a refreshing feeling, good light color reproduction.

â–  Luminous flux

The amount of light energy emitted by a luminous body through a certain cross section per unit time is called luminous flux. The greater the amount of luminous flux, the stronger the visible light emitted by the luminous body. The unit of luminous flux is expressed in lumens. The number of lumens is related to the type and power of the light emitter. The greater the power of a certain type of light emitter, the higher its lumens number. Conversely, if the number of lumens continues to decrease, it indicates that the luminous flux continues to decrease, indicating that the lifetime of the luminous body or the luminous power is decreasing.

What are the common raw materials for energy-saving fluorescent lamps?

Phosphor is one of the important materials for the manufacture of fluorescent lamps. Its quality is directly related to the efficacy of fluorescent lamps, luminous flux maintenance rate, color temperature, color rendering index and other parameters.

â–² Halo

Due to the cheap price of halogen powder, the luminous efficiency is continuously improved (currently the luminous efficiency of fluorescent lamps can reach 80 lumens/watt or so), and it has been the most important luminous material in fluorescent lamps since the late 1940s. However, there are two shortcomings of this kind of phosphor: one is itself unable to solve the contradiction between fluorescent lighting effect and color rendering, such as the warm white fluorescent lamp whose luminous efficiency reaches 80 lumens per watt, the color rendering index is only 50, and The daylight color fluorescent lamp with a color index of 75 has a luminous efficiency of only 60 lumens per watt. Since the halogen powder type fluorescent lamp has a particularly low maintenance ratio and the lamp life is very short, such an energy-saving fluorescent lamp loses its energy-saving significance.

â–² Rare earth trichromatic phosphor

In 1974, Fostergen et al. used a tricolor phosphor containing a rare earth element (a red phosphor was a europium-activated europium oxide, a green phosphor was a gallium-activated magnesium aluminate, and a blue phosphor was activated by a bivalent europium The magnesium lanthanum aluminate) has completely overcome the disadvantages of the halogen powder after it was applied to the phosphor, and a 38-mm, 40-watt rare-earth trichromatic fluorescent lamp was produced, which has not only high light efficiency (80 lumens per watt) but also color rendering. Good (color rendering index 85) solves the contradiction between the luminous efficacy and color rendering of the halogen lamp in more than 30 years. And rare earth trichromatic phosphors are much more resistant to short-wave UV than halogen powders. However, due to the fact that the cost of rare earth tricolor phosphors is nearly 30 times higher than that of halogen powders, many merchants still produce traditional halogen powder lighting sources.

High quality light source—rare earth trichromatic fluorescent lighting

â–  About three primary colors

The so-called three primary colors are the three basic colors of red, green, and blue. After being mixed and combined, they can be warm white light for lighting. As a mature energy-saving lamp technology, rare-earth trichromatic fluorescent lamps are recognized as a new type of high-efficiency and energy-saving electric light source in the world today (the so-called energy-saving lamps). Compared with ordinary incandescent lamps, the energy-saving rate is as high as 70%. Compared with metal halide lamps, sodium lamps, and mercury lamps, the energy-saving rate is as high as 60%; it overcomes the HID lamp's thermal pollution, light pollution, and radiation pollution; it has no infrared and ultraviolet radiation, and its emitted thermal energy is as low as 80%, compared with traditional Straight tube light color ratio, rare earth trichromatic fluorescent lamp color rendering index is quite good, is the best daylight-type light source.

â–  Rare earth trichromatic lighting - internationally recognized green light source

At present, the lighting modules in the integrated ceiling generally use three-color T5 ring lamps, but many businesses still use ordinary fluorescent tubes as lighting sources.

The trend of energy-saving light sources in integrated ceiling lighting modules is smaller and smaller, from the initial T12, T10, T8 to the current T4, T5, but the light efficiency is getting higher and higher, compared with the ordinary lamp light efficiency 50% increase, service life increased by 150%; a 7W rare earth trichromatic energy saving lamp's brightness is equivalent to 45W incandescent lamp, and the service life is 8 times that of ordinary incandescent lamp, low temperature, good light efficiency, no glare, energy saving good.

In general, when a rare earth trichromatic fluorescent lamp is used as an integrated ceiling lighting source, the environmental color is purely non-distorted, energy-saving and environmentally friendly, and the frequency flicker rate is greatly reduced, which can effectively protect the health of eyesight when used, especially in the kitchen. Three-color fluorescent lamps can effectively restore the color of food or dishes and present the true color, fragrance, and taste of the kitchen.
