Household L ED lamp with multiple light sources and adjustable illumination range
The invention relates to a large-range household L ED lamp with multiple light sources and adjustable illumination range.
L ED lamp is a electroluminescent semiconductor chip, which is solidified on the support by silver glue or white glue, then the chip and the circuit board are connected by silver or gold thread, the periphery is sealed by epoxy resin, which protects the inner core wire, finally the shell is installed, so the L ED lamp has good anti-seismic performance.
L ED illuminating lamps are widely used in the existing illumination field, but the functions of the existing L ED illuminating lamps are too single when the existing L ED illuminating lamps are used, and the L ED illuminating lamps are mostly designed in white, so that visual fatigue can be caused by long-time use of the lamps.
Disclosure of Invention
The invention aims to provide a household L ED lamp with multiple light sources and adjustable illumination range, which solves the problems in the background art.
In order to achieve the purpose, the invention provides the following technical scheme:
the utility model provides a domestic L ED lamps and lanterns of adjustable illumination zone of many light sources, includes the lamp stand, the outside bottom cover of lamp stand is equipped with the lamp shade, and L ED fluorescent tube is installed to the bottom of lamp stand, and the lateral wall bottom of lamp shade is equipped with the shot-light, the bottom of shot-light is articulated mutually with the lamp shade through first articulated seat, the outer wall axial symmetry of lamp shade sets up flutedly, be equipped with the screw rod in the recess, the bottom of screw rod is passed through the bearing frame and is rotated and install in the recess, still be equipped with the swivel nut on the screw rod, install the articulated seat of second on the outer wall of swivel nut, the articulated seat of second is connected and is served at the connecting rod, the other end of connecting rod is connected with third articulated seat, the top at the shot-light is installed to the third articulated seat, still be equipped with fixing bearing in the recess, the screw rod passes through fixing bearing and is connected with the recess rotation, the spout has been seted up on the diapire of recess.
As a further scheme of the invention: driven gear is installed on the top of screw rod, and annular mounting groove has been seted up to lamp stand outer wall upper level, and the lamp shade is outside to the mounting groove, installs the ring gear through the installation bearing in the mounting groove, and the ring gear meshes with driven gear mutually.
As a still further scheme of the invention: the outer diameter of the gear ring is larger than the diameter of the lamp holder, an outer sleeve is mounted at the top of the gear ring, and the outer sleeve and the base are coaxially arranged.
As a still further scheme of the invention: and the upper end of the outer wall of the outer sleeve is provided with a rotating plate.
As a still further scheme of the invention: threaded holes are formed in the side wall of the outer sleeve, and fastening screws are arranged in the threaded holes in a matched mode.
Compared with the prior art, the invention has the beneficial effects that: the invention has simple and reasonable structure, is fast and convenient to use, is hinged with the spot lamp on the outer side wall of the lampshade, and the outer sleeve is rotated by the rotating plate, the outer sleeve can drive the gear ring to rotate, the gear ring can drive the screw rod to rotate through the driven gear, when the screw rod rotates, the screw sleeve arranged on the screw rod can not rotate along with the screw rod because of the matching of the sliding block and the sliding groove, so the screw sleeve can only move along the sliding groove through the sliding groove, when the screw sleeve begins to slide in the chute, the screw sleeve can drive the top of the spot light to move through the connecting rod hinged on the outer wall of the screw sleeve, and the bottom of shot-light articulates on the lamp shade through first articulated shaft again, therefore when the shot-light top removed, contained angle between shot-light and the lamp shade will change, borrow this to realize the regulation of shot-light irradiation angle, can select suitable irradiation angle according to the occasion of difference, is fit for using widely.

The technical solution of the present patent will be described in further detail with reference to the following embodiments.
Referring to fig. 1-3, a household L ED lamp with multiple light sources and adjustable lighting range comprises a lamp holder 1, a lampshade 2 is sleeved at the bottom of the outside of the lamp holder 1, a L ED lamp tube 3 is installed at the bottom of the lamp holder 1, four spot lamps 5 are arranged at the bottom of the outer side wall of the lampshade 2, the four spot lamps 5 are uniformly distributed on the outer side wall of the lampshade 2, the bottom of each spot lamp 5 is hinged to the lampshade 2 through a first hinge seat 4, grooves 6 are axially symmetrically formed in the outer wall of the lampshade 2, screws 7 are arranged in the grooves 6, the bottom ends of the screws 7 are rotatably installed in the grooves 6 through bearing seats 8, screw sleeves 9 are further arranged on the screws 7, a second hinge seat 10 is installed on the outer wall of the screw sleeves 9, the second hinge seat 10 is connected to one end of a connecting rod 11, the other end of the connecting rod 11 is connected to a third hinge seat 12, the third hinge seat 12 is installed at the top of the spot lamp 5, a fixed bearing 13 is further arranged in the grooves 6, the screws 7 are rotatably connected to the grooves 6 through fixed bearings 13, a sliding groove 14 is formed in the bottom wall of the groove 6, a sliding block 14 is parallel to the sliding block 6, the sliding block 14 is arranged on the sliding block 14, when the sliding block 15 of the sliding block 5 is mounted on the sliding block 5, the sliding block 7 is capable of the sliding block 7, the sliding block 7 is capable of sliding block, when the sliding block 9, the sliding block 7 is capable of sliding block, the sliding block 9, the sliding block 7.
Driven gear 16 is installed on the top of screw rod 7, and annular mounting groove 17 has been seted up to lamp stand 1 outer wall upper level, and 2 outsides of lamp shade are located to mounting groove 17, install ring gear 19 through installation bearing 18 in the mounting groove 17, and ring gear 19 meshes with driven gear 16 mutually, and through rotating ring gear 19, ring gear 19 alright have rotated with driven gear 16 drive screw rod 7, realize unified regulation to screw rod 7.
The outer diameter of the gear ring 19 is larger than the diameter of the lamp holder 1, an outer sleeve 20 is arranged at the top of the gear ring 19, and the outer sleeve 20 and the base 1 are coaxially arranged.
The upper end of the outer wall of the outer sleeve 20 is provided with a rotating plate 21, and the gear ring 19 can be more easily rotated by rotating the outer sleeve 20 through the rotating plate 21, so that the adjustment of the spot lamp 5 is realized.
The side wall of the outer sleeve 20 is provided with a threaded hole 22, a fastening screw 23 is arranged in the threaded hole 22 in a matched mode, the fastening screw 23 can conveniently position the outer sleeve 20, and the outer sleeve 20 is prevented from rotating when the spotlight 5 is not required to be adjusted.
This practical theory of operation: during the use, rotate outer sleeve 20 through changeing board 21, outer sleeve 20 can drive ring gear 19 rotatory, ring gear 19 alright drive screw 7 through driven gear 16 and rotate, when screw 7 rotates, the swivel nut 9 of installation on the screw 7 can lead to swivel nut 9 can't follow screw 7 to rotate together because of slider 15 and the cooperation of spout 14, consequently swivel nut 9 can only remove along spout 14 through spout 15, when swivel nut 9 begins to slide in spout 14, swivel nut 9 just can drive the top removal of shot-light 5 through articulated connecting rod 11 on its outer wall, and the bottom of shot-light 5 articulates on lamp shade 2 through first articulated shaft 4 again, consequently, when the removal of shot-light 5 top, contained angle between shot-light 5 and the lamp shade 2 will change, borrow this realization to 5 regulation of shining the angle of shot-light.
Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
