As people pay more attention to family environment art, desk lamp because its decoration in the console and a few special status, also want to emphasize the unique decorative effect. Home with a lamp to begin to gradually split into the process table lamp and writing desk lamp two categories. The former pursues appearance, will develop train of thought on material innovation, modelling of divergent, to match the style of a variety of home decoration. The emphasis of the writing desk lamp is the lighting effect. Main research topics on the color temperature, illumination and lighting of the scientific indicators, in a safe, efficient, no glare, no stroboscopic to measure the quality of standard room desk, coffee table, bedside cabinets or corner cabinet, decorative frame on, put a beautiful lamp often play a unique effect, a desk lamp with a sense of design, not only to create a rich hierarchy of indoor light environment, but also because of its unique effect, for the room to add a touch of bright most craft table lamp is composed of a lamp holder and a lamp shade. The lamp holder is composed of ceramic, stone, cloisonne, bamboo, marble and other materials. Lampshade common glass, metal, plastic, fabric of bamboo and rattan made, the lamp holder and the lamp cover a by skillfully with, the desk lamp become beautiful works of art craft table lamp put less emphasis on functional lighting, some craft table lamp and even the use of colored glass diffuse lighting and mantle craft table lamp design is very important, emphasizing arts and decorative effect lamp lampshade intention is to focus light and increasing the brightness. But for craft table lamp, the lamp shade has become the designers to show their talents, and some were designed into the dome type, and some are designed into the shape of a straw hat, is really have the best no matter what the article, a lampshade and a lamp socket ultimately presented the overall design effect. In addition, with the rich color of the lamp, consumers have more room for choice.

Desk lamp color on the market currently has milky white, orange yellow, grass green and so on, according to the style of the decoration of the room to choose different styles and materials of the lamp, thereby and other devices form a perfect match today with the emergence of the new light source and a group of sculptural art lamp appeared. The process of the lamp, from the exterior, or is a flower vase, or a cartoon villain, a mermaid, the light was hidden inside in the era of knowledge economy, each family member actually have when using the writing desk to write books to read a book, so write a light source lamp based layout study lighting environment, local lighting effect is still very necessary to study lighting lights, lamps with lamp based writing, considering its brightness, but also pay attention to its appearance, its shape, color should be elegant Juanxiu calm, elegant, suitable for the study of learning environment research shows that, when viewed object surface illumination to 1000 lux, the human eye to see things the most clear, the most comfortable. Writing desk can increase the desktop illumination to this standard, I am afraid it is considered when the choose and buy the focus at present, market on the writing desk lamp light to incandescent lamp, quartz halogen lamp and eye protection lamp mainly.

The power consumption of 40W-60W incandescent lamp as the light source, without light ballast, the price is cheap, the price gap is mainly reflected in the other shell process, but the power consumption of incandescent lamp, high surface temperature, flash, low illumination, short lamp life, coupled with the light bulb is spherical point light source, it is difficult to form a larger high and uniform illumination the area, therefore, in developed countries no longer as written by lighting, but only as a decorative lamp using quartz halogen lamps with 30W-50W halogen lamp as the light source, need ballast, the price is a little expensive than incandescent illumination, than the same wattage incandescent lamp high of nearly 50%, 1 times the length of life, because the bulb only a small finger size, a lamp can be very small, other than the avant-garde. But this small halogen lamp light source of the surface of the heat, the light is dazzling, touch will cause burns, so must cover the protection. In addition, the lamp is typical of the point source, far and near brightness changes very difficult to on the desktop formation a big appearance characteristic of large enough high luminance area writing desk is with a reflecting cover, a lower opening, direct hit. Pay more attention to the design of glass and porcelain enamel plastic currently on the market the writing desk lamp, metal coil, work table, a clamp spring type rocker arm suspension lamp and seat type adjustable light lamp and seat type adjustable light lamp, copper building in the classical pillar type single double porcelain lamp shade, a groove shaped double double color lamp shade, classic candle desk lamp, the old kerosene lamp lamp of type of double lamp chief mother lamp a novel writing desk lamp has the advantages of convenience, practicality, alarm and lamp combination, a miniature electric fan and lamp combination, there will be a beacon, stationery box and lamp combination of writing desk lamp is not transparent or semi transparent, so that the light. The luminosity and the line of sight distance are defined, the general distance of 30 cm and 45 cm, light and line of sight form a 45 degree angle to the writing desk if it is to the reading Lang were special, that in addition to the brightness, but also to avoid the strobe. Daily use of AC source, due to the size of the voltage changing, often replacement of light and shade, the light flashes in known as the stroboscopic. Strobe as per second within 100, which belongs to the low frequency flicker, the eyes of people have strong stimulation and harm, for a long time in the source read,, prompted young eyes dry, sore eyes and eye fatigue, likely to cause myopia.
