Abstract
A lighting apparatus comprises a lamp holder and a lamp stand which are socket-jointed together through a joint head and an adaptor. A sliding block for forming an angle between the joint head and the adaptor is held between the inner wall of the joint head and the adaptor, and the sliding block can move axially between the joint head and the adaptor in order to regulate the angle. By adopting the technical proposal, the angle between the joint head and the adaptor can be regulated by moving the sliding block between the joint head and the adaptor, thereby achieving to the purpose of regulating the inclination of the lamp holder in order to satisfy the requirement of light distribution.
Description
Technical field
The utility model relates to a kind of lighting device.
Background technology
Light fixtures such as street lamp are the requirement of satisfying luminous intensity distribution in installation process, lamp holder need be set certain inclination angle, transitional street lamps is usually all by realizing the crooked certain angle of lamp stand, yet, set the inclination angle in this way, just can't change easily once determining, thereby, which need adjust under the situation at light fixture inclination angle just inapplicable to.
The utility model content
In view of this, be necessary to provide a kind of light fixture of regulating the lamp holder inclination angle.
A kind of light fixture, comprise lamp holder and lamp stand, this lamp holder and this lamp stand are by a pullover and adaptor cup jointing together, being folded with one between described pullover internal face and the described joint makes this pullover and this joint form the slide block of an angle, this slide block can move between described pullover and described joint vertically, so that the size of described angle changes.
Owing to adopted technique scheme, by moving the slide block that is folded between pullover and joint, can regulate the corner dimension between pullover and the joint, thereby reach the purpose of regulating the lamp holder inclination angle, to satisfy light distribution requirements.
With reference to the accompanying drawings, the utility model will be further described in conjunction with specific embodiments.
Description of drawings
Fig. 1 is the three-dimensional assembly diagram of light fixture among embodiment of the utility model.
Fig. 2 is the partial enlarged drawing of the pullover and joint of light fixture among Fig. 1 when decomposing.
Fig. 3 is in the axial direction partial sectional view when pullover and joint make up under first state among Fig. 2.
Fig. 4 is in the axial direction partial sectional view when pullover and joint make up under second state among Fig. 2.
Fig. 5 is diametrically cutaway view when pullover and joint make up under second state among Fig. 2.
The specific embodiment
Fig. 1 and 2 shows the light fixture 1 in preferred embodiment of the utility model, and in the present embodiment, this light fixture 1 is the LED street lamp.This light fixture 1 mainly comprises lamp holder 10, lamp stand 20 and the slide block 30 that is used to regulate lamp holder 10 inclination angles.
The internal diameter of pullover 12 openends is slightly larger than the external diameter of joint 22, make pullover 12 can be socketed on the joint 22 by openend, and pullover 12 roof to the distance between diapire is dwindled (showing as Fig. 3) by close lamp holder body 11 places gradually to the direction of openend, after making pullover 12 to be socketed on the joint 22, form an annular gap between the outside wall surface of internal face pullover 12 and joint 22, and can make pullover 12 can swing up and down with respect to joint 22, to reach the purpose of adjusting pullover 12 and 12 angles of joint.
In the present embodiment, swing with respect to joint 22 in order to prevent pullover 12, the equal and opposite in direction (as shown in Figure 5) of slide block 30 left and right sides thickness spacing just and between joint 22 and pullover 12 both sides, make slide block 30 both sides outer rims respectively with pullover 12 both sides internal faces near.Also be provided with one the 3rd keeper 60 at pullover 12 upsides near in the screw 121 of open end, with fixing with pullover 12 with joint 22 in close open end.In the present embodiment, above-mentioned this first keeper 40, second keeper 50 and the 3rd keeper 60 are the column screw member, for example, and bolt, screw etc.
In addition, need to prove, the shape of slide block 30 is not limited to ring-type, it is configured to ring-type in the present embodiment mainly is for slide block 30 being combined with joint 22 preferably, in other occasions, having under the cooperation of suitable combination, slide block 30 can be provided with and be Any shape, for example, by the mode that forms dovetail groove forming the dovetail structure on the slide block on joint that slide block and junction is fashionable, slide block just can be provided with and be square shape etc.
Fig. 3 shows in the present embodiment pullover 12 in the axial direction partial sectional views when making up under first state with joint 22, as can be seen from the figure, slide block 30 is positioned at the position of pullover 12 the most close lamp holder bodies 11 this moment, correspondingly, 40 sides that are positioned at mounting hole 122 the most close lamp holder bodies 11 of first keeper that are attached thereto.The support portion of slide block 30 be folded in pullover 12 and joint 22 between, make pullover 12 and joint 22 between form an angle.
Fig. 4 shows in the present embodiment pullover 12 in the axial direction partial sectional views when making up under second state with joint 22, as can be seen from the figure, slide block 30 on joint 22 vertically to by having moved certain distance, at this moment, first keeper 40 is positioned at mounting hole 122 side of close openend, because the support portion thickness of slide block 30 is constant, it will promote pullover 12 upwards upsets in the process that moves right, make pullover 12 and joint 22 between angle increase, thereby the purpose that has realized regulating the light fixture inclination angle.Need to prove especially,, can be adjusted in any angle between the upper and lower bound of inclination angle as required, make the adjusting at lamp holder inclination angle practical more flexibly owing to adopt slide block 30 to endwisely slip to regulate the inclination angle in joint 12 upper edges.
Again together with reference to Fig. 2, in assembling process, at first take off the cover plate 124 of pullover 12 downsides, slide block 30 is put into pullover 12, make the projection 33 of slide block 30 upside support portions 31 extend in pullover 12 the mounting hole 122, carry out Primary Location with 40 pairs of slide blocks of first keeper 30.Then, be socketed on the joint 22 of lamp stand 20 pullover 12, and slide block 30 be set in position suitable on the joint 22 according to the needs of luminous intensity distribution.Fixing with slide block 30 with first keeper 40 again with pullover 12, with second keeper 50 that slide block 30 is fixing with joint 22, fix (as Fig. 3 show) with pullover 12 in open end and joint 22 with the 3rd keeper 60.At last, with screw 125 protecting cover 124 is covered in the perforation 124, protecting pullover 12 inside, and finish assembling, during dismounting, the reverse operating above-mentioned steps gets final product, and does not repeat them here.
