Abstract

A kind of lighting apparatus, wherein speculum 13 can be with respect to moving between a plurality of in the enclosure positions, the slit 11 of shell 10, and lamp socket can integrally move for shell 10 with speculum 13.Lamp 14 is housed in the lamp socket, thereby the light beam that lighting apparatus in use sends is launched by slit 14.This configuration mode makes and need not mobile shell 10 and just can change radiative direction, also can not increase scattering of light degree and/or dazzle simultaneously.

Description

Lighting apparatus

The invention relates to a kind of lighting apparatus.

Lighting apparatus of the present invention comprises: a shell has the slit on the shell; Lighting apparatus is in use promptly by this slit emission bright dipping; A speculum, can be integrally between in the enclosure a plurality of positions with respect to this slit motion; With a lamp socket, can integrally move together with speculum with respect to shell.

The most handy hinge of one end of speculum is connected on the interior fixing point of shell.

The shell of lighting apparatus can also have an erecting device, and like this, lighting apparatus just can be contained on the pillar.That fixing point at the hinged place of speculum is preferably away from erecting device in the case.

For simplicity, also positioner should be arranged on the shell of lighting apparatus and the speculum, make reflection be placed in a plurality of prepositions with respect to the slit.Positioner should be located on the speculum position away from hinge.Positioner can be installed some alignment pins, also can install the retainer that can be placed in selectively in a plurality of holes.

Erecting device preferably has the carriage of an adjustable angle joint, in the case, can install the indicator that can see from the outside on the shell, so that the indication shell is with respect to the angle of carriage.Erecting device can also be equipped with (preferably flexible) bolt device, and shell can be placed on a plurality of prepositions selectively with respect to carriage.

For simplicity, shell has a demountable part, and the electrical control gear of the lamp of lighting apparatus is equipped with in the inside.

Preferably be equipped with a baffle plate in the shell to reduce the degree of dazzling the eyes of light, the best and integral body of speculum formation of this baffle plate.

The best circle in all or all basically edges of shell.

Referring now to accompanying drawing, further illustrates content of the present invention.In the accompanying drawing:

Fig. 1 is the diagrammatic side view of lighting apparatus of the present invention;

Fig. 2 is the rear perspective of lighting apparatus;

Fig. 3 is and the similar view of Fig. 1, but shows the situation that lighting apparatus is installed as artificial moonlight.

Earlier referring to Fig. 1 and Fig. 2, the lighting apparatus shown in the figure is total has a shell 10, one side along the slit 11 that has of shell 10, lighting apparatus is in use promptly by this slit emission bright dipping.Diffuser 12 closes slit 11, thereby whole casing forms the integral body of complete closed.Dispose speculum 13 and lamp 14 in the shell 10, lamp 14 is the discharge type fluorescent tube preferably.Baffle plate 15 forms an integral body with speculum 13, to reduce the degree of dazzle.

Lighting apparatus can also have the installation bracket 16 of a U-shaped cassette, and like this, lighting apparatus is contained on the pillar (for example mast, this is not shown in the drawings) with regard to the installing of desirable top or the mode that hangs.Shell can be angled and rotate with U-shaped card 16, and this makes and can change angle between lighting apparatus and the pillar.Be provided with a flexible bolt device (not shown) between U-shaped card 16 and the shell 10, this device can be placed on arbitrary position of a plurality of predetermined different orientations shell 10 selectively.The indicator 17 that U-shaped Ka16Chu is provided with an angle gauge formula is adjoined in shell 10 outsides, in order to indicate the angle of above-mentioned orientation.The size of angle gauge 17 and the mode of configuration will reach the purpose that is easy to read.

Shell 10 has a part 18 adjoining U-shaped Ka16Chu, and the electrical control gear of lamp 14 is equipped with in the inside.This part system designs to such an extent that to make it be to alleviate the weight of lighting apparatus and windage and can unload down from the remainder of shell under need being placed in away from the situation of lighting apparatus at control device.

All or all basically edges of shell 10 all are circular.This not only makes outward appearance catchy, and is convenient to clean by rainwater the outside of shell.

Speculum 13 is hinged on the fixing point 19 of shell away from an end of U-shaped card 16, thereby shell can be integrally with respect to slit 11 swings.The part of adjoining of the other end of speculum and shell is equipped with positioner, this device to make speculum can remain on arbitrary position in a plurality of predetermined swing position selectively.Do not specifically illustrate positioner among the figure, but positioner can be got the form of alignment pin, not so also can be made of a bolt on the speculum 13 for example, this bolt can embed a series of intersegmental in the holes that are provided with apart from one another by on the shell selectively.Lamp 14 is contained in 1 (not shown) of lamp, and lamp socket is then installed to such an extent that it can be moved with respect to shell 10 with 13 one-tenth integral body of speculum.

In the specific embodiment of being lifted, speculum 13 is to design to such an extent that make the axis of its light that sends become 65 degree angles with the normal of its frontal plane." neutrality " position shown in A, the frontal plane of speculum is arranged essentially parallel to the plane in slit 11, thereby light becomes 65 degree angles to penetrate from lighting apparatus with the plane in slit 11.But the position of speculum 13 can be adjusted to respectively in the position shown in B, C and the D, in these positions, though light is still constant with respect to the angle of speculum, becomes 60 degree, 55 degree and 50 degree ground to occur with the normal on 11 planes, slit.

Modern lighting apparatus requires to reduce the pollution level of light as far as possible, and promptly the key light of lighting apparatus must project desired direction, prevents that simultaneously light scattering from producing dazzle on other direction or on other direction.For example, its light that scatters to side and back of searchlight (as shown in Figure 3) that is contained in ground should lack as far as possible, otherwise may make the pedestrian feel disagreeable.In the general lighting equipment of speculum fix in position, can only move whole lighting apparatus during the angle that regulate light beam and regulate its angle.So just change the slit with respect to the angle of object on every side, thereby also changed the place (from observer's angle) the when slit stops light beam.If the slit in the lighting apparatus of An Zhiing can not prevent effectively that again astigmatism from arriving observer's eyes, then will make the people dazzle the eyes again.

By contrast, make in the above-mentioned structure, can keep shell motionless, just can change light beam with respect to the angle of structure body on every side as long as change the position of speculum in shell.Like this, slit 11 remains unchanged with respect to observer's position, thereby light beam is subjected to the situation of cutting identical all the time, therefore can not dazzle the eyes.

The speculum of some lighting apparatus is made up of two parts, and the position of first in shell is constant, and the position of second portion in shell becomes.But when changing the position of speculum second portion, the whole shape of speculum has become, thereby the characteristics of luminescence of lighting apparatus has also just become.Like this, second portion only mobile mirror changes the angle of light beam again though can make shell keep motionless, and the change of the characteristics of luminescence may well cause undesirable dazzle.
