Abstract
The utility model relates to a shadow-free and adjustable desk lamp which comprises a lamp holder, a supporting rod and lamp cap adjustment devices, wherein the lamp cap adjustment devices comprise a fixed seat, left and right lamp shade devices and telescopic rods; the supporting rod is connected with the fixed seat to form a connection body to support the lamp shade devices; the lamp shade devices are symmetrically connected with the two ends of the fixed seat via the telescopic rods respectively; grooves are formed at the two ends of the fixed seat; one end of each telescopic rod is fixed in each groove; the depth of each groove is greater than the retraction length of each telescopic rod; the telescopic rods are fully sunk into the grooves after retraction; and a lead wire in the lamp holder penetrates through the supporting rod, penetrates through the two telescopic rods via the supporting rod, and then is connected with the lamp shade devices. After stretching, the lamp shade devices are unfolded to the two sides and concentratedly irradiate a small area via a plurality of point light sources to eliminate shadow; and after the lamp shade devices retract to the middle, the telescopic rods are sunk into the grooves, and the two lamp shade devices form a whole, so that the desk lamp can serve as a common desk lamp for use.
Description
Technical field
The utility model relates to a kind of without shadow adjusting desk light, and one can regulate bulb angle, avoids the device of light shade.
Background technology
Desk lamp be during people live, be used for illumination a kind of household electrical appliance.It is generally divided into two kinds, and a kind of is column, and a kind of have a clip.Its operation principle is mainly that light is concentrated in a pocket, is convenient to working and learning.The bulb that general desk lamp is used is incandescent lamp or energy-saving bulb, and also having a kind of is exactly popular on the market eye-protecting desk lamp.
Desk lamp of a great variety on market now, but people are in the time using desk lamp type, often have shadow and interrupt the view, and also bulb connects mostly, not only impact illumination after breaking down, and also it is large to change cost, brings unnecessary trouble.
Utility model content
Just to the problems referred to above, it is a kind of without shadow adjusting desk light that the utility model provides, it makes simple novelty, utilize simple rod member principle, reach the effect of cancellation shade, and overall appearance cheapness, lampshade can elongate and shorten, can also either direction rotate and rotation, reach the custom that meets user's demand.
The utility model solves the technical scheme that its technical problem adopts: a kind of without shadow adjusting desk light, comprise lamp socket, support bar and lamp holder adjusting device, it is characterized in that, described lamp holder adjusting device comprises holder, lampshade device, expansion link, support bar is connected with holder, and form disjunctor, for supporting lampshade device; Lampshade device is divided into two of left and right, is connected to symmetrically respectively the two ends of holder by expansion link; The two ends of described holder are respectively provided with a groove, and expansion link one end is fixed in groove, and the length after the depth ratio expansion link of groove shrinks will be grown, and expansion link all submerges in groove after shrinking.The wire of described lamp socket inside passes support bar, then passes respectively two expansion link inside by support bar, then connecting lamp closure assembly.After lampshade device stretches, launch to both sides, increase the area of light-illuminating, and contrast can be eliminated middle shade mutually; After lampshade device shrinks to centre, expansion link submerges in groove, and two lampshade devices form an entirety, can be used as common desk lamp and uses.
The beneficial effects of the utility model are: the utility model simple structure novelty, utilize simple rod member principle, and reach the effect of cancellation shade, and overall appearance cheapness, lampshade can elongate and shorten, and can also either direction rotate and rotation, reaches the custom that meets user's demand.

Detailed description of the invention
Below in conjunction with brief description of the drawings and embodiment, the utility model is described in further detail.
In the first embodiment shown in Fig. 1, Fig. 2, a kind of without shadow adjusting desk light, comprise lamp socket 5, support bar 4 and lamp holder adjusting device 1, it is characterized in that, described lamp holder adjusting device 1 comprises holder 3, lampshade device, expansion link 2, support bar 4 is connected with holder 3, and forms disjunctor, for supporting lampshade device; Lampshade device is divided into two of left and right, is connected to symmetrically respectively the two ends of holder 3 by expansion link 2; The two ends of described holder 3 are respectively provided with a groove, and expansion link 2 one end are fixed in groove, and the length after the depth ratio expansion link 2 of groove shrinks will be grown, and after expansion link 2 shrinks, all submerges in groove.The wire of described lamp socket 5 inside passes support bar 4, then passes respectively two expansion link 2 inside by support bar 4, then connecting lamp closure assembly.After lampshade device stretches, launch to both sides, increase the area of light-illuminating, and contrast can be eliminated middle shade mutually; After lampshade device shrinks to centre, expansion link 2 submerges in groove, and two lampshade devices form an entirety, can be used as common desk lamp and uses.
In the second embodiment shown in Fig. 3, Fig. 4, Fig. 5, lampshade device comprises lampshade 6, fluorescent tube 8, deck 9 and clamping hinge 10, and lampshade 6 is in the arc-shaped, and both sides are extend outwards respectively, forms extension board 7, for collecting light, strengthens light intensity; Described deck 9 is located at the inner side of lampshade 6 stiff ends, and fluorescent tube 8 is fastened on deck 9.
Described clamping hinge 10 is for having the universal spherical hinge of certain clamping dynamics, and its one end is fixed on the outside of lampshade 6 stiff ends, other end connection expansion link 2, and lampshade 6 can, around clamping hinge 10 any direction rotation and rotations, be convenient to adjust the direction of illumination of light.Clamp hinge 10 and need to use certain dynamics and move, position that can fastening lampshades 6, avoids rotating because of self gravitation; When lampshade 6 moves fluorescent tube 8 relative position downwards, the shade that fluorescent tube 8 is luminous in the middle of eliminating completely, reaches the effect of shadowless lamp.
These are only specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this.Any taking the utility model as basis, for realizing essentially identical technique effect, do ground simple change, be equal to replacement or modification etc., be all covered by among protection domain of the present utility model.
