Adjustable luminaire and its adjusting method
Technical field
The present invention relates to lighting apparatus and method and technology field, specifically a kind of adjustable luminaire and its adjusting side
Method.
Background technique
Lamps and lanterns, refer to can light transmission, distribution and the utensil for changing light source light distribution, including in addition to light source it is all for fixed and
Whole components needed for protecting light source.Normally, lamps and lanterns include lampshade, are located at lamp source periphery to optically focused, assemble light
Together, suitable brightness is set with structure in place.But existing lamps and lanterns and lampshade are usually fixed, Wu Fagen
Factually the case where border and the congregational rate of light is adjusted in demand.
Present applicant discloses a kind of adjustable luminaire in the patent that patent publication No. is CN204879611U
The device of exposure intensity and range realizes the rotation of adjustable side plate by steel ball, locating slot and rotation fixing axle, and passing through can
The rotation for adjusting side plate adjusts the exposure intensity and range of lamps and lanterns.But the device remains shortcoming, for example, should
Device can not be arranged to inclined surface in the two sides of lamp holder mounting portion, otherwise will stop the rotation of adjustable side plate, thus the dress
Vertical plane can only be arranged in the two sides of lamp holder mounting portion by setting, however, vertical plane can be to lamp source two sides compared with inclined surface
Range of exposures and exposure intensity, which are formed, to be hindered, and the set-up mode of inclined surface would be even more beneficial to the irradiation of lamp source, and therefore, it is necessary to set
Count a kind of novel adjustable luminaire and its adjusting method.

The gear assembled structure includes a fixing axle, and described fixing axle one end is connected with the fastening lampshades,
The other end of the fixing axle is connected with knob, by turning knob, enable to the gear assembled structure rotate from
And the rack combination structure rotation being meshed with gear assembled structure is driven, and drive the tune of moving parts progress position in turn
It is whole.
The position that the lamp bracket backboard corresponds to the fixing axle is equipped with through-hole, and the other end of the fixing axle is worn
It is connected after crossing the through-hole with the knob.
The lamp source is equipped with inter panel in the side of lamp bracket backboard opposite to each other, for reflecting the light beam of lamp source.
The gear assembled structure includes a fixing axle, and the fixing axle outer sheath is equipped with rotation gear, described
Rotation gear with rack combination structure for being meshed.
The sliding block that the rack combination structure includes slide track seat and matches with slide track seat, the sliding block side are equipped with
Mobile rack, the mobile rack with gear assembled structure for being meshed.
The present invention also designs a kind of adjusting method of adjustable luminaire, and the method is as follows:The rotation gear set
It closes structure and rack combination structure is made to generate displacement, to drive moving parts to carry out the adjustment of position and and then adjust movement
The spotlight effect of lampshade.
The present invention compared with the existing technology, the advantage is that:Structure novel and succinct feasible, by gear assembled structure and
The rational design of rack combination structure can easily realize the adjusting of lights crowds and lamps and lanterns range of exposures.

Specific embodiment
The present invention will be further explained below with reference to the attached drawings, and the structure and principle of this device and method are to this profession
It is very clearly for people.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
Referring to Fig. 1 and Fig. 2, in present embodiment, the adjustable luminaire includes lamp bracket backboard, lampshade backboard both ends to
Downside is opposite to be equipped with extended segment, and the outer end of extended segment is connected with lamp holder that is opposite and setting, can connect lamp source between lamp holder, extend
It is that fastening lampshades is equipped in the space between lamp source upside and lamp bracket backboard downside between section, in the middle part of the lamp bracket backboard and admittedly
Determine correspondingly to be equipped with the through-hole for being connected and fixed axis in the middle part of lampshade, fixing axle is by fixed hub and bolt is realized and lamp bracket
Backboard and fastening lampshades are rotatedly connected.Rotation gear, fixing axle and rotation gear structure are also arranged on the outside of the fixing axle
At gear assembled structure, rack combination structure includes being fixedly linked with mobile lampshade by bolt or welding or other connection types
