Environmental protection lamps should first: low working voltage, low power consumption, stable performance, long service life (generally 6.5438+10,000 hours), strong impact resistance and vibration resistance.
Does not contain infrared and ultraviolet components, has high color rendering and strong luminous directionality; Good dimming performance, no visual error when the color temperature changes; The cold light source has low calorific value and can be safely touched; Improve glare, reduce and eliminate light pollution. Zero stroboscopic, no eye fatigue.
No electromagnetic radiation, prevent radiation pollution and protect the brain. It provides a comfortable lighting space and can well meet people's physiological health needs. It is an environment-friendly and healthy light source.
Long-term use can protect eyesight and prevent myopia. When choosing lamps and lanterns, high-quality light source is the basis of green lighting.
A high-quality light source should have the following three characteristics. First, there must be no ultraviolet light and infrared light in the spectral components.
Long-term excessive exposure to ultraviolet rays is not only easy to cause keratitis, but also harmful to lens, retina and choroid. Infrared rays are easily absorbed by water and absorb too much infrared rays when they gather through the lens of human eyes. Over time, the lens will degenerate, leading to cataracts.
Second, the color temperature of light should be close to natural light. People live in natural light for a long time, and the human eye has strong adaptability to natural light and good visual effect.
Third, the lights are stroboscopic. The power supply frequency of ordinary fluorescent lamp is 50 Hz, that is to say, it lights up and down 100 times per second, which is a low-frequency flash, which will make the regulating organs of human eyes in a tense state of adjustment, leading to visual fatigue.
If the luminous frequency is raised to several hundred or tens of thousands of hertz-high frequency, the human eye will not feel stroboscopic.
2. What little common sense do you have to know about exquisite lamps?
1 lamps with predetermined voltage and frequency must be used.
2 All grounding lamps must be regularly checked for grounding.
3 When the ambient temperature is between 5℃ and 35℃, lamps with special restrictions and regulations are generally used. ..
4 indoor lamps and lanterns cannot be moved to outdoor use.
Ordinary lamps and lanterns should not be used above or near heaters such as electric heaters, gas stoves and kerosene stoves, nor should they be used in places where steam is directly encountered.
6 Lamps and lanterns cannot be installed with bulbs exceeding the specified wattage.
7 When changing lights, removing covers and removing fuses, the power supply must be cut off.
8 safety lighting lamps and lanterns should be checked regularly to ensure that there is no abnormality.
9. The emergency light is in high temperature gas (140℃).
10 Articles such as paper and cloth cannot be placed near or covered with the lighting device.
3. What common sense do you need to master when buying lamps?
Modeling color.
Lighting should make the finishing point indoors. Too complicated shapes and colors are not suitable for rooms with simple design.
Easy to use. Most people have experienced the embarrassment of changing the bulb of ceiling lamp: standing on the table, standing on the chair, holding their heads at 90 degrees and raising their arms 2.
A ceiling five meters high or higher. When choosing lamps, we must consider the convenience of replacing bulbs.
Save electricity and energy. Energy-saving bulb saves electricity, has good illumination, does not emit too much heat, and is suitable for multiple headlights.
Energy-saving bulbs are mostly standard screws, and chandeliers have two calibers. One is standard, you can use energy-saving light bulbs. One is non-standard, and energy-saving light bulbs cannot be used. Attention should be paid when choosing: spotlights are mostly non-energy-saving products.
Safety comes first. Be sure to choose lamps from regular manufacturers.
Ordinary products are marked with the total load. According to the total load, how many watts can be used for light bulbs, especially for multi-head chandeliers, that is, the number of light bulbs * wattage per light bulb = total load. In addition, waterproof lamps should be used in bathrooms and kitchens with high humidity.
Lamp function. Rooms with different functions should be equipped with different styles and lighting.
The living room should use bright and rich lamps; The bedroom should choose the lamp that makes people lie on the bed unconsciously; Children's rooms should use colorful lamps; Waterproof lamps with simple style should be used in the bathroom; The kitchen should choose lamps that are easy to wipe and clean; Some places that need special performance can also choose to shoot lights.
4. Environmental protection tips related to lamps and lanterns
4, home lighting power saving tips
(1) Try to choose efficient lighting lamps.
On the premise of ensuring effective lighting and brightness, choose electric light sources and lamps reasonably. Self-ballasted fluorescent lamps can be used instead of incandescent lamps, and small-diameter double-ended fluorescent lamps can also be used instead of large-diameter double-ended fluorescent lamps. For example, a 5 watt self-ballasted fluorescent lamp is equivalent to a 20 watt incandescent lamp, and a 16 watt self-ballasted fluorescent lamp can be equivalent to a 60 watt incandescent lamp.
(2) The installation height of lamps and lanterns should be appropriate.
For example, if a 20-watt fluorescent lamp is installed one meter high, the illumination is 60 lumens; 0.8 meters high is 93.75 lumens; If the height is reduced properly, the wattage of the lamp can be reduced.
(3) Make full use of reflection and reflection.
If the lamp is equipped with a suitable reflector, the illumination can be improved, and the illumination can be improved by about 20% by using the reflection of indoor walls.
(4) Install dimming and power saving device
If incandescent lamps are used for bedside lamps and ceiling lamps in the living room, dimming and power-saving devices should be installed.
(5) Avoid using ever-burning lamps.
Acousto-optic delay switch should be used for lighting stairs and corridors, or turn off the lights in time after people leave.
(6) When watching TV programs, only turn on the required electric lights.
It can not only save electricity, but also protect eyesight.
(7) Electronic ballast and energy-saving inductive ballast shall be used for double-ended lighting.
The power consumption of electronic ballast is only 4 watts, while that of traditional inductive ballast is 9 watts.
5. What are the maintenance tips for lighting?
Step 1: Install the lampshade when installing the lamp. Before installing lamps, you must consider the long term. There will always be dust in the space, and the lamp has stronger adsorption to dust. On the basis of not causing great influence on the appearance of the lamp, it is necessary to install a lampshade, which can effectively prevent external pollution.
In addition, there are two special places that need different protective measures, that is, the bathroom and the kitchen. The water vapor in the bathroom is too heavy, so we must pay attention to protecting the lamps. Once the electrical appliances encounter water, they are basically abandoned, so it is necessary to install a moisture-proof lampshade in the bathroom and take ventilation measures. The kitchen fumes are very heavy. If you don't protect the lamp from smoke, there is nothing you can do in the future.
Step 2: Use the correct cleaning method. This step is the most critical step in the maintenance tips of lamps, because the installation of lampshades is not a once-and-for-all thing, and dust and lampblack cannot be completely isolated, so the daily cleaning of lamps is particularly important. Generally speaking, it is safer to clean lamps with dry cloth, but for nonmetallic lamps, we can use wet cloth to clean them, provided that the subsequent drying measures are done well and the structure of lamps can be disassembled for cleaning, but we must remember the installation order. No special cleaning solution is needed for daily cleaning. If it is really dirty, be sure to use a special cleaning solution to ensure that the lamp is not damaged.
Step 3: It is easy to find the aging of lamps in time and replace them in time. If it is not found in time, it will cause even bigger problems. Many people don't take the aging of lamps seriously and think it's not bad. In fact, the aging of lamps is a warning before the occurrence of lamp problems. If it is not replaced in time, the ballast will burn out, not to mention whether the whole lamp will go wrong. For people, this is also a big security risk. Step 4: Don't switch lamps and lanterns frequently. This step is the simplest step in the whole lighting maintenance skill. It can be said that it is a problem of behavior habits. "Turn off the lights at will" doesn't actually save energy. It is a waste of electricity to turn on and off, and it also has a great influence on the lights. If they are turned on frequently, the filament temperature will rise sharply, thus accelerating the sublimation speed, and the service life will naturally be greatly shortened.
6. Is there any trick to choose me as a lamp?
Z It has something to do with where you put the lights in your bedroom. Lighting around the bed can provide lighting for the host at night.
You can set a desk lamp on the bedside table and use a translucent lampshade, so that the light can be soft and not dazzling. You can also choose warm colors to set off this atmosphere.
The advantage of this placement is that the owner can reach out and touch the switch. There are some lights on the wall above the bedside, just to meet the needs of reading in bed.
Many people like to read some magazines before going to bed, and install an adjustable reading lamp above the middle of the bed, which will not reflect light or glare, and will not affect the rest of the people next to them; Or install a work lamp beside the bed and let it shine on the wall to get a good reading environment. When installing reading lighting, avoid direct light or use it with other lighting to prevent eye fatigue.
If there is a dresser in the bedroom, it should be placed in a place with sufficient natural light. At the same time, small spotlights can be set on both sides of the mirror to make up for the lack of light. Installing a spotlight on the top of the mirror will affect sleep and may produce ugly images.
In order to avoid reflection, it is best to use elastic ceiling lamp for mosaic mirror, and the illumination angle is 45 degrees. It is also necessary to install lighting equipment around and inside the side cabinet.
Especially some big wardrobes, without the help of lighting, it is very inconvenient for the owner to find clothes. A fluorescent lamp can be installed at the top of the cabinet door to provide uniform white light.
Or install a small spotlight on the top edge of the cabinet, which is not only practical, but also very decorative. Children's bedrooms should be equipped with adjustable lighting, and children's psychological development is not yet mature. The light in the bedroom can soothe their inner fears.
An adjustable lamp with low brightness is both energy-saving and practical. If there is a baby at home, avoid lamps with long practical wires to avoid danger.
Novel desk lamps will arouse children's interest, and cartoon-style desk lamps are very suitable for children. Bedrooms for school-age children often have the function of study. Choose an adjustable desk lamp to give your eyes a proper rest, so as to develop good study habits.
There should also be some decorative lights in the bedroom. For example, the wall lamp at the bedside can not only provide reading light, but also render the colors of decorative paintings. Light hitting the curtains can create a soft atmosphere; Candlelight releases a romantic atmosphere. Decorative lighting is a supplement to functional lighting, but it is dazzling to avoid blindly pursuing luxury in setting.
What are the tips of 7.7? LED dental lamp?
The LED dental lamp was originally conceived by two Japanese designers (Yuan Jingshiqiao and Zhenguo Daikuan) at the Ghost Festival. The LED lamp was put into a transparent alveolar through high-tech treatment, which is a bit like a mouthguard. When the wearer smiles, it will glow. Used on a commercial model of a clothing store run by a kid.
I didn't expect this move to be imitated by many young fashion people in Japan. Japan's best-selling fashion magazine "Little Devil" seized this business opportunity, bought the designer's products and patent rights, and quickly launched the LED dental lamp (LED dental paste) of Little Devil, which was sold in a small scale in fashion gathering places such as Harajuku and Shibuya in Tokyo, Japan, and sold out within 1 hour.
Coincidentally, the British "Daily Mail" also quickly made a special report on this strange but fashionable led dental lamp, entitled "Japan's new fashion: LED lamps for your teeth". Critics call it a bright smile because it is particularly dazzling at night. The report said, want to have a dazzling smile? LED dental lamp (LED dental paste) can help you realize this wish.
Decorating teeth with LED dental lights is very popular in Japan and has become a new fashion. 2。
Japanese girls are eager for this new product, which has promoted the sales of LED dental lamps to make great strides. At first, the practice of setting gold and diamonds in teeth was all the rage. LED dental lamps are more creative, and it may only be a matter of time before they are popularized outside Japan.

Comparison of characteristics between soft colors of three-wavelength white light 58 ~ 95, 84 and 5000 and ordinary light sources
Efficiency of light source type (Lm/.
Color rendering index Ra refers to the degree to which a light source as a light source renders the real color of an object, so the color characteristics are approximately described by the correlated color temperature. Because the gas discharge light source is generally a discontinuous spectrum, it gives people a cold feeling, and its value is close to 100, which is not completely consistent with the continuous spectrum of blackbody radiation. There are two kinds of light sources with color development. When the color temperature exceeds 5300K K, the color temperature (or correlated color temperature) is lower than 3300K, which shows that the color deviation of the object under light can reflect the color characteristics of the light source more comprehensively than under reference light (sunlight).

Six. The color rendering of light source is represented by the color rendering index. JDR type 10~20 100 has excellent color rendering 3000. People often use light sources with color temperature higher than 4000K, which gives people a warm feeling, JC and comfortable effect to show the beautiful color of food. The proportion of outdoor light sources is 70%, and the color rendering index of other light sources is lower than 100, so the color rendering is the best: it is necessary to clearly emphasize specific colors, lighting in places and corners such as toilets.
Fluorescent color 45~70 53 or 4 100 white light.
The daylight color of fluorescent lamp is 45~75 74, which can be 6500 blue light, and its comprehensive beam output is reduced to a specific number of hours.
Correlation color temperature k When the color of light emitted by a light source is close to the color radiated by a blackbody at a certain temperature, it is necessary to use a light source with high color rendering index (Ra), a clearly visible study room and a warm atmosphere in order to correctly express the original color of a substance.

9. What tips do you need to buy safety lights?
Guide: How to choose safe lamps? The following is decorated by Kunming Baiyi for you! To choose lamps with high safety performance, we should pay attention to the following aspects. Pay attention to the sign on the product: (1) See if the manufacturer's name, trademark, model, rated voltage and rated power are safe; (2) Ceiling lamps, wall lamps, table lamps and floor lamps installed on the surface of wooden materials shall be lamps marked with F symbol. How to choose safe lamps? To choose lamps with high safety performance, we should pay attention to the following aspects. Please pay attention to the mark on the product:
(1) See whether the manufacturer's name, trademark, model, rated voltage and rated power are safe;
(2) Ceiling lamps, wall lamps, table lamps and floor lamps installed on the surface of wooden materials shall be lamps marked with F symbol.
Pay attention to electric shock protection. Electric shock of lamps and lanterns is generally caused by using unqualified lamp holders or not covering the live parts of lamps and lanterns. Usually, when a lamp is used, the light bulb is screwed on. After the lamp is electrified, people should not touch the live part.
Pay attention to the cross-sectional area of the conductor used in the lamp: when buying, you can look at the marks printed on the outer insulation layer of the conductor on the lamp, and the cross-sectional area of the conductor should be at least 0.5mm/ square. It is stipulated that the minimum cross-sectional area of wires for lamps and lanterns is 0.5 mm/square. In order to reduce the cost, some manufacturers only use 0.2mm/ square wire in their products. Under abnormal conditions, the wires will be burnt out, and the insulation will be short-circuited and dangerous. Pay attention to the structure of lamps and lanterns:
(1) There should be no sharp edges at the entrance and exit of the metal pipe through which the conductor passes. Measures can be taken to chamfer or sheathe the metal parts to avoid cutting the conductor, electrifying the metal parts and causing electric shock.
(2) Portable lamps, such as desk lamps and floor lamps, should have a junction block at the entrance of the power cord, because 1. Eliminate stress, and avoid the wire falling off the terminal when pulling the wire, which will lead to electrification of the metal shell and electric shock; 2. Prevent the power cord from contacting the heating element when it is pushed back, and prevent the insulation layer from melting due to overheating of the conductor, and the * * * conductor contacts the metal shell, and the shell is charged, resulting in electric shock.
