To Learn More about Lighting Knowledge，Lighting Knowledge Summary
I. Overview Light is the expression of space and architecture. Lighting is not only limited to lighting, but also focuses on its artistry and comfort.
II. Classification, Brand and Characteristics Lamps and lanterns are classified according to appearance and style: chandelier, desk lamp, floor lamp, wall lamp, downlight, bathroom heater, energy-saving lamp, fluorescent lamp, induction lamp, ceiling lamp, etc.
1. Characteristics Chandeliers are suitable for living rooms. The chandeliers have the most patterns, including European candlestick chandeliers, Chinese chandeliers, crystal chandeliers, parchment chandeliers, fashion chandeliers, conical cap lanterns, pointed flat cap lanterns, waist cap lanterns, five-prong ball chandeliers, yulan cap lanterns, olive chandeliers, etc. There are two types of chandeliers for living rooms: single-head chandeliers and multi-head chandeliers. The former is mostly used in bedrooms and restaurants. The latter should be installed in the living room. The installation height of the pendant lamp shall be at least 2.2 meters from the ground.
(1) European candlestick chandelier European classical style chandeliers are inspired by the candlestick lighting methods of ancient people, who placed several candles on the hanging iron. Nowadays, many chandeliers are designed in this style, only changing candles into bulbs, but bulbs and lampholders still look like candles and candlesticks.
(2) Crystal chandelier There are several types of crystal lamps: rock crystal cut-and-grind model chandeliers, heavy lead crystal blow-molded chandeliers and low lead crystal blow-molded chandeliers. Crystal glass pendant lamp, crystal glass pendant lamp, crystal glass die casting cutting pendant lamp, crystal glass bar pendant lamp, etc.
At present, most crystal lamps on the market are made of imitation crystal, but the materials used in imitation crystal are different. Crystal lamps of good quality are made of high-tech materials, while some inferior crystal lamps even use plastic as imitation crystal materials, resulting in poor light and shadow effects. Therefore, when buying, we must carefully compare and identify.
(3) Chinese chandelier The classical Chinese chandelier is bright and agile, suitable for installation in the lobby area. At the entrance, the bright light gives people a warm and cheerful atmosphere, while the Chinese pattern will tell those who make public impetuous guests that this is a traditional family. It should be noted that the specifications and styles of lamps should be matched with the living room. In addition, if you want to highlight screens and decorations, you need to add spotlights.
④ Fashion chandelier Most people may not want to decorate into European classical style, and modern chandeliers are often more popular. At present, there are many modern chandeliers in the market, and there is a lot of room for selection. All kinds of lines can be selected.
2. Selection Consumers had better choose chandeliers that can install energy-saving lamps. Don’t choose the pendant lamp with electroplated layer, because the electroplated layer will fade over time. Select all-metal and glass chandeliers that are consistent inside and outside.
Consumers should not choose chandeliers that are too cheap. At present, the quality of chandeliers around 200 yuan can be guaranteed to a certain extent. The quality of chandeliers below 100 yuan is generally poor. Luxury chandeliers are generally suitable for duplex houses, while simple low-pressure lanterns are suitable for ordinary houses. The highest grade and the most expensive are crystal chandeliers, but there are few real crystal chandeliers. Crystal chandeliers are mainly sold in Guangzhou, Shenzhen and other places. The sales volume in the north is very small, which is also related to the air quality in the north, because the dust on crystal chandeliers is not easy to clean.
Consumers had better choose the chandelier with sub-control switch, so if the chandelier has more lamp caps, it can be partially lit.
(2) Table lamp
1. A. work desk lamp: multiple joints, flexible, suitable for the workplace.
B decorative table lamp: roughly divided into model and dimming type, suitable for decorative environment.
C jade desk lamp: mainly made of wood lamp body and cloth lampshade series, with bright colors, suitable for children’s study and people who need a relaxed living environment.
D. eye-protecting desk lamp: ultra-high frequency electronic ballast is adopted to achieve the effect of no stroboscopic light. some desk lamp bases are equipped with dumping power-off switches, which are safe and reliable. as long as they are suitable for students, they are especially popular at present.
2. Selection The choice of desk lamp mainly depends on the quality of electronic accessories and the manufacturing process. Generally, the electronic accessories of desk lamps from small manufacturers are of poor quality and the manufacturing process level is relatively low. Therefore, consumers should choose the desk lamps produced by large manufacturers. Generally, living rooms and bedrooms are decorated with table lamps, while work tables and study tables are equipped with energy-saving eye-protecting table lamps, but energy-saving lamps cannot be dimmed.
(3) Floor lamp 1. Characteristics Floor lamps are often used for local lighting, not comprehensive, but emphasizing the convenience of movement, which is very practical for creating a corner atmosphere. If the lighting mode of floor lamp is directly projected downward, it is suitable for reading and other activities requiring concentration. If it is indirect lighting, the overall light change can be adjusted. The bottom of the lampshade of the floor lamp should be more than 1.8m from the ground.
2. Selection Floor lamp is usually placed at the corner of sofa. The light of floor lamp is soft. When watching TV at night, the effect is very good. The lampshade of floor lamp has a variety of materials, and consumers can choose according to their own preferences. Many people like floor-to-ceiling lamps with small countertops, because they can place fixed phones on small countertops.
(4) Wall lamp 1. Characteristics Wall lamps are suitable for bedroom and toilet lighting. Commonly used are double-headed yulan wall lamp, double-headed olive wall lamp, double-headed drum wall lamp, double-headed lace cup wall lamp, jade pillar wall lamp, mirror front wall lamp, etc. The installation height of wall lamp shall be no less than 1.8m from the ground.
2. Selection The higher-grade wall lamps in the market are priced around 80 yuan, while the lower-grade wall lamps are priced around 30 yuan. The choice of wall lamp mainly depends on the structure and shape. Generally, mechanical molding is cheaper and manual molding is more expensive. Iron wrought wall lamps, all-copper wall lamps, sheepskin wall lamps and so on all belong to high-grade wall lamps, among which iron wrought wall lamps sell best. In addition, there is also a digital perpetual calendar wall-hanging lamp with a lamp and a picture. This wall-hanging lamp is very popular with consumers because it can be used for lighting, decoration and calendar.
(5) Spotlights 1. Characteristics Spotlights can be placed around ceiling or on top of furniture, or in walls, dados or skirting lines. The light directly shines on the household utensils that need to be emphasized, so as to highlight the subjective aesthetic effect and achieve the artistic effect of highlighting the key points, unique environment, rich levels, rich atmosphere and colorful colors. Spotlights are soft and elegant, which can not only play a leading role in the overall lighting, but also partially light and contrast the atmosphere.
2. Selection Spotlights are divided into low-voltage and high-voltage types. Consumers had better choose low-voltage spotlights, which have longer service life and higher luminous efficiency. The lighting effect of spotlights is reflected by power factor. The higher the power factor, the better the lighting effect. The power factor of common spotlights is about 0.5, which is cheap. The power factor of high-quality spotlights can reach 0.99, which is slightly more expensive.
(6) Downlight 1. Characteristics Downlight is generally installed on the surrounding ceiling of bedroom, living room and toilet. This kind of concealed lamp embedded in the ceiling projects all the light downward and belongs to direct light distribution. Different reflectors, lenses, blinds and bulbs can be used to obtain different light effects. Downlight does not occupy space, which can increase the soft atmosphere of space. If you want to create a warm feeling, you can try to install more downlights to reduce the pressure of space.
2. Selection The main problem of downlights lies in the lamp socket. Some miscellaneous downlights have lamp sockets that are not resistant to high temperature and are easy to deform, resulting in the bulb not being screwed down. At present, all lamps and lanterns can only be sold after passing 3C certification. consumers should choose downlights that pass 3C certification.
(7) Yu Ba
1. Characteristics Bathroom heaters are divided into bulb infrared heating bath heaters and heater heating bath heaters according to heating methods. The market is mainly bulb infrared heating bath heaters. According to the function, there are three-in-one bathroom heater and two-in-one bathroom heater. The three-in-one bathroom heater has lighting, heating and exhaust functions. The two-in-one bathroom heater has only lighting and heating functions. According to the installation method, it can be divided into concealed bathroom heater, exposed bathroom heater and wall-mounted bathroom heater. The concealed bathroom heater is more beautiful. The exposed bathroom heater is directly installed on the top. Generally, wall-mounted bathroom heater is not allowed for concealed and exposed bathroom heater. In general, bath tyrants produced by regular manufacturers have to pass the “cold and hot alternating performance test” of “standard full inspection” and spray under 4℃ ice water to undergo instantaneous cold and hot tests, and then use warm gun explosion-proof glass to ensure absolute safety in bathing.
2. Selection The bathroom heater is warm as long as the light shines on it, which has little to do with the size of the room and mainly depends on the skin temperature of the bathroom heater. Yuba has 2, 3, 4 bulbs, generally 2, 3 bulbs for rooms with heating and 4 bulbs for rooms without heating. Standard Yuba bulbs are 275 watts, but low-quality bulbs have a slow heating rate and cannot reach the temperature specified by 275 watts. When choosing a bath bully, consumers can stand 1 meter away from the bath bully, turn on the bath bully and feel the heating speed and temperature of the bath bully. The heating speed is fast and the temperature is relatively higher.
(8) Energy-saving lamps
1. Characteristics Energy-saving lamps are superior to ordinary incandescent bulbs in brightness and service life, especially in saving electricity. Energy-saving lamps are U-shaped, spiral-shaped and petal-shaped, with power ranging from 3 watts to 40 watts. Prices of energy-saving lamps vary greatly from model to model, from specification to origin. Energy-saving lamps can generally be installed in downlights, chandeliers, ceiling lamps and other lamps. Energy-saving lamps are generally not suitable for use in high temperature and humidity environments. Bathrooms and kitchens should avoid using energy-saving lamps as much as possible.
2. Selection In order to buy energy-saving lamps in a guaranteed lighting market, we should first select well-known brands, and confirm that the products are packaged completely with complete signs. The outer package usually explains the service life, color rendering and correct installation position of energy-saving lamps. Energy-saving lamps are divided into halogen powder and tricolor powder. tricolor powder has superior comprehensive performance than halogen powder. some merchants sell halogen powder as tricolor powder, deceiving consumers.

Compared with inductive ballasts, electronic ballasts can improve the light efficiency of lamps and systems, can start instantaneously, and prolong the life of lamps. At the same time, it has small temperature rise, no noise, small volume, light weight, and power consumption is only 1/3 to 1/4 of that of inductive ballast, so consumers should choose electronic ballast ceiling lamp. The annular lamp tube of ceiling lamp has halogen powder and tricolor powder, and the tricolor powder lamp tube has good color rendering, high luminous intensity and slow light decay; Halogen powder lamps have poor color rendering, low luminosity and fast light decay. Distinguishing halogen powder from tricolor powder lamp can light both lamps at the same time. Place your hands near the two lamps.

The purchase of lamps and lanterns Generally speaking, it is advisable to choose solemn and bright chandeliers or ceiling lamps in the living room. If the room is relatively high, it is advisable to use incandescent chandeliers or a large round chandelier, which can make the living room appear transparent, but it is not advisable to use all downward light distribution chandeliers, and the upper space should also have certain brightness to reduce the brightness difference between the upper and lower spaces. If the room is lower, ceiling lamps and floor lamps can be used, so that the living room looks lively and elegant, with a sense of the times. The shape and color of the lamps should be coordinated with the furniture in the living room.
The study lighting should be bright and soft, and the lamp with incandescent bulb is more suitable. The desk lamp of the writing desk should adapt to the nature of work and the needs of study. It is appropriate to choose a direct-fired desk lamp with a reflective cover and an opening at the lower part, i.e. a working desk lamp or a writing desk lamp. The light source of the desk lamp is usually incandescent lamp and fluorescent lamp. A small spot lamp can be installed in the bookcase. This kind of lighting can not only help to identify the title of the book, but also keep the temperature to prevent the books from rotting and damp.
The bedroom should be equipped with several kinds of lamps, ceiling lamps, desk lamps, floor lamps, bedside lamps, etc., which should be adjusted and mixed at will to create a warm atmosphere. Wall lamp and floor lamp can be used to replace the ceiling lamp in the center of the room. Wall lamps should use diffuse material lampshades with low surface brightness, which can make the light in the bedroom appear soft and conducive to rest; It is also possible to install a hanging main lamp at an appropriate position in the room and a wall lamp at the head of the bed. These lamps should be operated separately.
The dining table in the restaurant requires horizontal illuminance, so it is advisable to choose lamps with strong direct downward irradiation or pull-down lamps so that the pull-down height is 600 mm to 700 mm above the table, and the lamps are generally located directly above the dining table. Lampshades should be made of glass, plastic or metal with smooth appearance so as to be scrubbed at any time. Floor lamps can also be used for lighting, and warm wall lamps can be properly arranged on nearby walls, which will make the atmosphere more lively and stimulate appetite when entertaining guests.
Ceiling lamps are commonly used in kitchens, bathrooms and aisles, because these places need less brightness of illumination, and have large water vapor and dust. Ceiling lamps are convenient to clean and protect bulbs. Lamps and lanterns in the kitchen should be installed in a place that can avoid steam and smoke. Glass or enamel lampshades should be used for easy scrubbing and corrosion resistance. Toilet should use bright and soft lamps, and lamps should have moisture-proof and rust-proof functions.
