Abstract

The utility model discloses an eye-protective table lamp, which comprises a base, a lamp rod, a lamp cover, a lamp tube and a strobe-eliminating power supply circuit. The utility model is characterized in that the lamp cover is externally provided with a plurality of assistant lighting light sources. Due to the assistant lighting bulbs on the lamp cover, the utility model realizes adjustment to the background light in the room, prevents weak brightness and releases eye fatigue, thereby providing perfect eye protection.

Description

Eye-protecting desk lamp

Technical field

The utility model relates to a kind of lighting device, is specifically related to a kind of photodistributed Table lamp structure that relates to.

Background technology

For realizing economize on electricity, solve of the injury of the stroboscopic of fluorescent lamp simultaneously to human eye, in recent years, read the fluorescent lamp that light source begins generally to use no stroboscopic.No stroboflash fluorescent lamp possesses following several characteristics: 1, white light; 2, brightness flicker free (promptly not having stroboscopic); 3, has bigger light-emitting area, to reduce large-area shade; 4, lighting angle is easy to regulate, and is even to guarantee the illumination on the desktop, and guarantees the eyes that light can the direct irradiation user; 5, luminosity can be regulated within the specific limits, reaches optimum value with the brightness that guarantees desktop.The appearance of this lamp has effectively alleviated the problem owing to the eyes muscular fatigue that inherent shortcoming caused of traditional lighting light source and eyesight decline, thereby is called as eye-protecting lamp.

But the illumination of desirable reading environment also has an important factor to consider, flat illumination that Here it is cooperates with background illumination.Flat illumination is meant the illumination of reading face under the lamp, and background illumination then is meant the illumination in other space and object in room the reading face.Existing reading desk lamp is a kind of light source of flat illumination, if one can only the desk lamp of flat illumination under reading study, at this moment except that desktop, be the dark space that nothing is thrown light in the room in, the reading environment that this light and shade contrast is strong easily causes eyes muscular fatigue.Simultaneously, single flat illumination also can be deprived the diastole condition of looking in the distance of vision system because of being the dark space at a distance.At this moment each regulating system of eye can be in all the time and see near nervous compressive state, eyes muscular fatigue meeting run-up under this state of regulating of can't looking in the distance, thus accelerate near-sighted generation and development speed.

This shows that desirable reading light source should be to take into account background illumination in flat illumination, the reading environment that both scientific matching and forming have three-dimensional illumination could effectively reduce eyes muscular fatigue and make that tired being difficult for accumulated.

At present, the reading desk lamp that generally uses of people be can only be unidirection luminous the flat illumination power supply.Want to make other space in the room to obtain the just necessary use another one of illumination background illumination light source, and other indoor lighting source generally is used for whole room illumination, power is bigger, and this has just caused the waste of the energy.

Summary of the invention

The utility model purpose provides a kind of eye-protecting desk lamp, when providing desirable reading face to throw light on, provides suitable background illumination as required.

For achieving the above object, the technical solution adopted in the utility model is: a kind of eye-protecting desk lamp, comprise base, lamp stand, lampshade, fluorescent tube and the corresponding stroboscopic power supply circuit that disappears, and in the described lampshade outside, be provided with a plurality of floor light light sources.

Above, described floor light light source can adopt any lighting source of the prior art, for example incandescent lamp bulb, microfluorescent lamp and its mfg, high brightness LED etc.; Its layout makes that surrounding space is evenly illuminated, and overall brightness does not generally need too bright, is equivalent to getting final product from vehement lamp illumination about 10 watts, is used to provide the bias light floor light.

Further technical scheme, described each floor light light source is respectively equipped with gauge tap.Thereby the user can determine the quantity that the floor light light source is opened as required, forms suitable background illumination.Certainly, also can gauge tap be set in groups controls.

Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:

1. desk lamp of the present utility model provides background illumination when no stroboscopic illumination is provided, thereby the excessive eye anxiety that causes of room illumination degree gap when having avoided existing desk lamp to work independently has played the effect of eyeshield;

2. secondary light source power of the present utility model is less, and gauge tap as required, has played energy-conservation effect.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model embodiment one.

Wherein: 1, base; 2, lamp stand; 3, lampshade; 4, bulb; 5, gauge tap.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment one: shown in accompanying drawing 1, a kind of eye-protecting desk lamp, comprise base 1, lamp stand 2, lampshade 3, fluorescent tube and the corresponding stroboscopic power supply circuit that disappears, in the described lampshade outside, be provided with 4 light emitting diode bulbs 4, lay respectively at the first half of lampshade, left and right half one and Lower Half, as the floor light light source, described base is provided with 4 gauge taps 5 controlling 4 floor light bulbs respectively simultaneously.Open the floor light light source during use simultaneously, background illumination can be provided, avoided the excessive eye anxiety that causes of room intraoral illumination degree gap, played the effect of eyeshield.

Claims

1. an eye-protecting desk lamp comprises base [1], lamp stand [2], lampshade [3], fluorescent tube and the corresponding stroboscopic power supply circuit that disappears, and it is characterized in that: in the described lampshade outside, be provided with a plurality of floor light light sources.

2. eye-protecting desk lamp according to claim 1 is characterized in that: described each floor light light source is respectively equipped with gauge tap [5].
