1, ceiling color should not be heavy The ceiling of the living room symbolizes the day and the floor symbolizes the ground. The color of the ceiling should be shallow, and the color of the floor should be deep, so as to conform to the meaning of “light weight and light weightâ€, so that there is no sense of top-heavy or pressure-topped. The ceiling of the living room symbolizes the color of the sky. Of course it is a light-colored one, such as light blue, which symbolizes the blue sky; while white symbolizes the white cloud. The color of the ceiling should be light, while the color of the floor should be blue to comply with light weight. 2, the living room should be installed round solar chandeliers The interior must give people a bright feeling, so the lighting of the living room should be sufficient, and bleakness will affect the career development. The choice of lamps in the ceiling of the living room is very important. It is best to use circular chandeliers or ceiling lamps because the circle has a full meaning. In some living rooms lacking in sunlight, the interior is dark and unclear. In this case, it is better to fill the light with fluorescent lamps hidden in the four sides of the ceiling. This kind of light is reflected from the ceiling, soft and not glare. The light emitted by the fluorescent lamp is closest to the sun, which is most suitable for living rooms lacking natural light. 3, ceiling should have Tianchi Affect the mood of daily life and work. The false ceiling is too low for the cross beam of the roof, neither in terms of feng shui or design. In this case, the use of low-lying four-sided and high-middle ceiling shapes is not only visually comfortable, but also creates a “Tianchi†that gathers water in the middle of the ceiling, which is of great benefit to housing. If you then hang a glorious crystal lamp in the center of the “Tianchi†of Jushui, you will have the finishing touch, but do not put a mirror on the ceiling. This is a feng shui taboo. 4, according to the living room ceiling Feng Shui principles The ceiling of the ceiling is the first taboo to use the type of mouth, and the ceiling of the glyph shape adds another person to the prisoner's character. Therefore, it is recommended that you use less glyph-shaped suspended ceilings. Secondly, to avoid the ceiling of fish bones, fish bones first represent poverty and poverty. No fish and meat are edible, and then the bone itself is a mustache, so of course it should be used with caution.

When a forward voltage is applied to the light-emitting diode, the holes injected from the P area to the N area and the electrons injected from the N area to the P area are respectively in contact with the electrons in the N area and the voids in the P area within a few microns of the PN junction. The holes recombine and produce spontaneous emission fluorescence. The energy states of electrons and holes in different semiconductor materials are different. When electrons and holes recombine, the energy released is somewhat different. The more energy released, the shorter the wavelength of the emitted light. Commonly used are diodes that emit red, green or yellow light. The reverse breakdown voltage of the light-emitting diode is greater than 5 volts. Its forward volt-ampere characteristic curve is very steep, and it must be used in series with a current-limiting resistor to control the current through the diode.

The core part of the light-emitting diode is a wafer composed of a P-type semiconductor and an N-type semiconductor. There is a transition layer between the P-type semiconductor and the N-type semiconductor, which is called a PN junction. In the PN junction of certain semiconductor materials, when the injected minority carriers and the majority carriers recombine, the excess energy is released in the form of light, thereby directly converting electrical energy into light energy. With reverse voltage applied to the PN junction, it is difficult to inject minority carriers, so it does not emit light. When it is in a positive working state (that is, a positive voltage is applied to both ends), when the current flows from the LED anode to the cathode, the semiconductor crystal emits light of different colors from ultraviolet to infrared, and the intensity of the light is related to the current.
