Description

A kind of lighting

Technical field

The utility model relates to a kind of lighting, especially a kind of multifunctional lighting lamps through architecture advances.

Background technology

Illumination condition when existing lighting uses with regard to it can be divided into two big classes usually.One class is diffuse illumination---for example common indoor lamp around illuminating by lamp holder self is luminous, is used for throwing light in a big way or comprehensive illumination.Another kind of is by reflecting and condensing device or/and the refraction beam condensing unit makes the light that is derived from lamp holder form the light beam of directional lighting---flashlight for example is used for the illumination among a small circle on certain direction.In addition, compare with first kind of lighting system, the light intensity in second kind of lighting system unit space is higher, can illuminate than distant location.

Generally speaking, people only need a kind of in above-mentioned two kinds of lighting systems.Yet, but can require to change illumination condition because of the variation of condition in some occasion.At this moment, often need to use different light fixtures could satisfy lighting requirement, convenient inadequately.

The utility model content

The purpose of this utility model is: at the problem of above prior art existence, a kind of multifunctional lighting lamps that can realize diffuse illumination and directional lighting by self simple transformation is respectively proposed, thereby satisfy different demands, offer convenience to the user to illumination condition.

In order to reach above purpose, lighting of the present utility model comprises a housing, one is arranged in the lamp socket that housing is electrically connected with a power supply by a switch, an and lamp holder that is placed on the lamp socket, one is connected in the lampshade that housing also centers on lamp holder, it is characterized in that: lampshade is by top lamp bowl, middle part light transmission casing and the installation position, bottom that is connected with housing constitute, this installation position has first and second operating positions at least, when lampshade is in first operating position, the lamp bowl is in around the lamp holder, when lampshade was in second operating position, light transmission casing was in around the lamp holder.

Like this, when lampshade is in first operating position, when promptly the lamp bowl is in around the lamp holder, under the reflecting condensation effect of lamp bowl, can sends directional beam, thereby satisfy the needs of directional lighting from the rim of a bowl; When making lampshade be in second operating position by regulating the adjustable mechanism that is located by connecting, when promptly lamp holder was positioned at the light transmission casing middle part substantially, the light that lamp holder sends saw through case scattering towards periphery, thereby satisfied the needs of diffuse illumination.

This shows that behind employing the utility model, the user can select diffuse illumination or directional lighting as required by the position of simple adjustment lampshade and shell, need not change light fixture, one-object-many-purposes is very convenient.

The specific embodiment

Multifunctional lighting lamps in the preferred embodiment one of the present utility model, its basic structure as Figure 1-3.Housing 10 is tubular, and the lower end is installed on the end socket 11 by the hinge with certain friction grip power, upper end plug-in mounting lampshade, and internal fixation is equipped with the column lamp socket 6 that is electrically connected with power supply by switch 12, assigns lamp holder 1 on the lamp socket 6.

Lampshade is made of the lamp bowl 9 on top, the pipe shape light transmission casing 2 at middle part and the installation position of bottom.Lamp bowl 9 has the parabolic reflective surface.The concrete structure of installation position comprises take-up housing 3, steel ball 4 and spring 5 as shown in Figure 3.The upper end cylindrical of take-up housing 3 inserts light transmission casing 2 endoporus lower ends and fixing, and take-up housing 3 centers have can be by the through hole of column lamp socket 1, and its underpart is shaped on radial hole, and spring 5 is contained in the hole, and steel ball 4 is settled in the aperture.Be fixed with positive stop strip 7 in the housing 10, be shaped on upper, middle and lower spacing hole 8 (spacing hole also can be formed directly on the housing and save other installation positive stop strip) on this positive stop strip, constitute the drawing and pulling type bindiny mechanism that can regulate and navigate on the diverse location thus.

When along the vertically upwards pull lampshade of tubular shell 10 when steel ball 4 will be absorbed in the upper limit hole under spring 5 effects, lamp holder 1 is positioned in light transmission casing 2 middle parts, the light that energising back light hair goes out sees through light transmission casing 2 scattering towards periphery, can satisfy the needs (referring to Fig. 1) of diffuse illumination.When along the vertically downwards push-press lamp cover of tubular shell 10 when steel ball 4 is absorbed in the lower limit hole under spring 5 effects, lamp holder 1 is positioned in the focus place at parabolic lamp bowl 9 middle parts, the light that energising back lamp holder 1 sends is under the reflecting condensation effect of lamp bowl 9, the directional beam that formation is sent from the rim of a bowl can satisfy the needs (referring to Fig. 2) of directional lighting.During spacing hole, the glazed area of light transmission casing reduces in steel ball 4 sinks into.In addition, in use,, also can adjust the angle between tubular shell 10 and the end socket 11, thereby change light angle according to the needs of different occasions.

The multifunctional lighting lamps of preferred embodiment two of the present utility model is shown in Fig. 4-7, and its basic structure and action effect are close with embodiment one, and end socket 11 ' is inserted on the power brick 13 ' as power supply among the figure.Lamp holder 1 ' is in light transmission casing 2 ' middle part substantially among Fig. 4, realizes diffuse illumination; Lamp holder 1 ' is in lamp bowl 9 ' middle part substantially among Fig. 5, realizes directional lighting.

Different with embodiment one is that the installation position of lampshade bottom is fixed on the nut 16 ' of light transmission casing 2 ' lower end by setting-in and screws the screw thread latch 15 ' that is fixed in the nut and constitutes (latch 15 ' is fixed on the lampshade lower end and gets final product).The adjustment circle 14 ' that can rotate in a circumferential direction with respect to tubular shell 10 ' is equipped with in the upper end of tubular shell 10 ', has helicla flute 17 ' on the inner circumferential wall of this adjustment circle, and the external part of latch 15 ' inserts in the helicla flute 17 '.

When screwing adjusting ring with respect to tubular shell 10 ', under the interaction of helicla flute 17 ' and latch 15 ', lampshade is with respect to tubular shell 10 ' vertically moving between the high-low limit position along housing 10 ', regulate thereby regulate the pull that replaces embodiment one with rotation, it is also very convenient to operate.

The structure of other part and effect can not given unnecessary details in addition referring to the description of embodiment one.

Need to prove that the foregoing description is nonrestrictive, all those skilled in the art with reference to spirit of the present utility model and design preferred embodiment being equal to of doing are replaced or the equivalent transformation scheme all drops in the desired protection domain of the utility model.
