Table lamp
First, process lamp
On the desks, coffee tables, bedside tables, corner cabinets, and decorative stands, a beautiful table lamp is often used to create unique effects. A table lamp with a design sense can not only create a rich indoor light environment, but also cause Its unique effect adds a touch of bright color to the room.
Most of the process table lamps are composed of two parts, a lamp holder and a lamp shade. The lamp holder is made of ceramic, stone, cloisonne, bamboo, marble and other materials. The lampshade is made of glass, metal, plastic, and fabric bamboo and rattan. Once the lamp holder and the lampshade are subtly matched, the table lamp becomes a beautiful artwork.
The craft desk lamp does not emphasize the lighting function. Some craft desk lamps even use diffused glass diffuser lighting and yarn cover.
The design of the process table lamp is very important, emphasizing artistic modeling and decorative effects. The lamp holder is modeled or elegantly vase-style, or pavilions and crowns are used, and some even use a novel telephone type.
The lampshade of a lamp is intended to concentrate light and increase brightness. However, for process lamps, their lampshades have also become places where designers show their talents. Some are designed to be dome-shaped and some are designed as straw hats.
No matter what the article is done, the lampshade and the lampholder will ultimately exhibit the overall design effect. In addition, with the rich color of desk lamps, consumers have more choices. At present, the colors of table lamps on the market are milk white, orange, grass green, etc. The lamps of different styles and materials can be purchased according to room decoration styles, thus forming a perfect match with other furnishings.
With the advent of new light sources, a number of sculptural technology table lamps have emerged. This kind of process light, from the appearance point of view, is either a flower vase that can be flowered, or a cartoon person, a mermaid, and the light source is hidden inside.
Second, writing desk lamp

In the era of knowledge-based economy, each family member actually uses the writing desk lamp to read and write. Therefore, it is still necessary to use a table lamp as the light source to arrange a study lighting environment.
The lighting of the study emphasizes the local lighting effects of the lighting. The lamps based on the writing desk lamp, under the premise of considering the brightness, should also pay attention to its appearance. Its shape and color should be elegant and graceful, suitable for the quiet and elegant learning environment of the study.
Studies have shown that when the illuminance of the viewed object reaches 1000 lux, the human eye sees the most clear and comfortable thing. Whether the writing desk lamp can raise the desktop illumination to this standard may be the focus of consideration when purchasing.
At present, the light sources used for writing table lamps in the market mainly include incandescent lamps, quartz halogen lamps, and eye protection lamps. Incandescent light bulbs use more power 40W-60W light source, do not need ballasts, cheap, price gap is mainly reflected in the modeling lamp shell process, but incandescent light power, high surface temperature, strobe, illumination The low bulb life is short. In addition, the bulb is a spherical point light source, and it is difficult to form a large uniform high-illumination area. Therefore, in developed countries, it is no longer used as a writing light, but only as a decorative light.

Quartz halogen lamps use 30W-50W halogen bulbs as light source, need ballasts, the price is slightly more expensive than incandescent lamps, illumination is nearly 50% higher than incandescent lamps with the same wattage, life is 1 times longer, because the bulb is only small finger size, can The luminaires are very compact and the styling is also more avant-garde. However, the surface of the small halogen lamp is hot and the light is dazzling. Touching can cause scalding, so it must be covered. In addition, this kind of lamp is a typical point light source, and the brightness and darkness vary greatly from near to far, making it difficult to form a sufficiently large high-illuminance area on the tabletop.
One of the major features of the writing desk lamp is a reflective hood with a lower opening and a direct firing style. Writing desk lamps on the market today include metal serpentine worktable lamp, clip spring rocker suspension table lamp, seat type dimmable plastic desk lamp, seat type dimmable enamel desk lamp, and copper seat classical pillar type single and double porcelain cover Table lamps, trough-shaped double-ceramic bi-color cover lamps, classical candlestick table lamps, ancient kerosene lamp-type lamps, and double-headed mother-of-glass table lamps.
The design of the new writing desk lamp pays more attention to its convenience and utility. There is an alarm clock combined with a desk lamp, a combination of a miniature fan and a desk lamp, and a combination of a pen holder, a pencil case and a desk lamp.
The lampshades of writing desk lamps are generally made of opaque or semi-transparent light, so that the lighting is concentrated. Its luminosity and people's line-of-sight distance are stipulated, generally 30 cm to 45 cm apart, and the light and the line of sight form an angle of 45 degrees.

Avoid strobing
If the writing desk lamp is dedicated to the readers, besides the brightness, the strobe light should be avoided. Daily use of AC light source, due to the constant change in the size of the voltage, often the phenomenon of light and shade replacement, this light flash phenomenon called strobe. Strobe is less than 100 times per second, which is low-frequency flash, which has strong stimulating damage to people's eyes. Reading and working under such a light source for a long time will promote juvenile dry eyes, eye pain and eye fatigue. It is easy to cause myopia.
At present, there is a non-stroboscopic vision health care desk lamp on the market. The ordinary alternating current signal is converted into a high frequency signal by electronic processing, so that people's eyes do not feel the strobe phenomenon, which is very beneficial to the protection of eyesight.
Experts remind parents that when choosing lamps for the students, they can carry a small gyro and rotate the gyro under the lights. If there is no optical illusion of reversal, it indicates that the lamps are not strobing.
