Abstract

The utility model relates to an automatic lift lamp, comprising a lamp holder 1, a lift controller 2, a lift control switch, a reeling electric motor 3, a lamp head 4, a lead wire 5 and metal contact sheets 8. The lamp holder 1 is hanged on a fixed construction. The lift controller 2 and the reeling electric motor 3 are connected together by the lead wire 5 through the lamp holder 1 by a power line. The beginning end and the final end of the power line are respectively connected with the positive electrode and the negative electrode of a power supply. The two metal contact sheets 8 are respectively connected with the positive electrode and the negative electrode of the power supply. The reeling on the reeling electric motor 3 is a soft insulated wire. One end of the reeling is connected with the lamp head 4 with a bulb. Two metal contact sticks on the lamp head 4 respectively contact the metal contact sheets 8 at the two sides. The lamp head 4 can rotate to lift upward and downward along with the reeling electric motor 3. When people replace the bulb on the lamp, the lamp head 4 with the bulb can descend as long as the lift control switch is pressed at the ground. The lift control switch is pressed again after the bulb is replaced. The lamp head 4 can rise to the place of contacting the metal contact sheets 8.

Description

Lifting lamp

Affiliated field

But the utility model relates to a kind of light fixture of automatic lifting, the especially unsettled overhead liftable light fixture of higher position that is fixed on.

Background technology

The light fixture that people used, most of light fixture are unsettled being fixed on the overhead higher building, if lamp is spoilt, change very trouble.Occurred on the market that for this reason liftable High-Pole Lamp and hand-operated lifting light fixture are arranged, the lifting High-Pole Lamp is to make whole lamp panel lifting by lamp stand, and the hand-operated lifting lamp is to take manual form to make the light fixture lifting, and they use still very trouble.

Summary of the invention

But the purpose of this utility model provides a kind of light fixture of automatic lifting, as long as people click direction switch, just can make the unsettled light fixture oscilaltion that is fixed on the building, convenient when more changing the bulb.

For achieving the above object, the utility model is achieved like this, it is made up of lamp socket, lifting controller, lift control switch, coiling electric motor, lamp holder, lead, metal contact.Lamp socket is unsettled to be fixed on the eminence building, and power line is by lamp socket, and a utmost point of power line connects with lifting controller with lead, and the other end of lifting controller connects with coiling electric motor with lead; Lift control switch can be formula wireless remote control type or wired, the positive and negative rotation of motor on it and the supporting control coiling electric motor of lifting controller; Coiling electric motor is made up of motor and the coiling on motor rotation axis, winds the line to be the flexible insulation line; Lifting controller and coiling electric motor are fixed on lamp socket or the building, and motor can make the coiling of down stretching rise or descend when rotating, and another utmost point of the other end of coiling electric motor and power supply connects; The hook ring of lamp holder is connected with coiling on the coiling electric motor, and two metal contactting rods are arranged on the lamp holder; Two metal contacts connect with the power supply positive and negative electrode respectively with lead, and corresponding with the metal contactting rod position on both sides on the lamp holder, and when the lamp holder that has the electricity bubble was raised to the top, both sides metal contact can contact the metal contactting rod on both sides on the lamp holder respectively.When people will change bulb on the overhead higher light fixture, as long as click lift control switch on ground, coiling electric motor is rotated, thereby the lamp holder that bulb is housed is descended, replacing finishes by lift control switch again, can make the lamp holder that changed bulb be raised to both sides metal contactting rod and two metal contact position contacting on the original lamp holder again.After adopting such structure, during the bulb of people on changing the unsettled light fixture that is fixed on higher position overhead, just very convenient.

Embodiment

As shown in FIG., the utility model is made up of lamp socket 1, lifting controller 2, lift control switch, coiling electric motor 3, lamp holder 4, lead 5, metal contact 8.Lamp socket 1 unsettled being fixed on the eminence building, power line is by lamp socket 1, the positive pole 6 usefulness leads 5 of power line connect with lifting controller 2, the other end of lifting controller 2 connects with coiling electric motor 3 with lead 5, the other end of coiling electric motor 3 connects with power cathode 7, connecting between lifting controller 2 and the coiling electric motor 3 can be that many leads 5 connect (not drawing in the drawings) mutually, to reach the purpose of motor 11 positive and negative rotations on the control coiling electric motor 3; Two metal contact 8 usefulness leads 5 connect with positive source 6, negative pole 7 respectively; Lift control switch is a wireless remote control type, and it is an independently remote controller (not drawing in the drawings), with the motor 11 positive and negative rotations on the lifting controller 2 supporting control coiling electric motors 3; Coiling electric motor 3 is made up of motor 11 and the coiling 12 on motor 11 turning cylinders, and coiling 12 is the flexible insulation line, and lifting controller 2 and coiling electric motor 3 are fixed on lamp socket 1 or the building; Hook ring 10 on the lamp holder 4 is connected with coiling 12 on the motor 11, two metal contactting rods 9 are arranged on the lamp holder 4, and corresponding with metal contact 8 positions on both sides, when the lamp holder 4 that has the electricity bubble was raised to the top, both sides metal contact 8 can contact the metal contactting rod 9 on both sides on the lamp holder 4 respectively.When people will change bulb on the overhead higher light fixture, on ground as long as press lift control switch, circuit between lifting controller 2 and the coiling electric motor 3 is connected, thereby coiling electric motor 3 is rotated, motor 11 can make the coiling 12 of down stretching descend when rotating, thereby the lamp holder 4 that bulb is housed is descended, change and finish again, can make the lamp holder 4 that changed bulb be raised to both sides metal contactting rod 9 and both sides metal contact 8 position contacting on the original lamp holder 4 again by lift control switch.

Certainly, above-mentioned lifting controller 2 and the front and back position of coiling electric motor 3 in circuit can be changed mutually, it is also unqualified with the selection that connects of positive source 6, negative pole 7 that they connect head and the tail two ends, back, as long as after the entire circuit connection finishes, lifting controller 2 is got final product by the 3 positive and negative rotations of lift control switch control coiling electric motor; In order to protect bulb, lamp holder 4 can be fixed on the lampshade the inside, and hook ring 10 on the lamp holder 4 and metal contactting rod 9 stretch out the lampshade outside, and when lamp holder 4 liftings, lampshade is lifting thereupon also like this; Lift control switch can be wired formula, it and lifting controller 2 are integrated, they are fixed on are operating the position that can touch with hand, they are connected with coiling electric motor 3, to reach the purpose of controlling the motor 11 positive and negative rotations on the coiling electric motor 3 with long lead on ground.
