Description

Lamp set

Technical Field

The utility model relates to the technical field of lighting fixtures, especially, relate to a lighting fixture.

Background

A lamp comprises a lamp holder and a lamp bulb. The lamp holder is a device for holding the position of the lamp and connecting the lamp to a power source. The lamp holder is used for connecting a lamp bulb, the lamp bulb is an incandescent lamp, and the incandescent lamp comprises a lamp holder, a glass bulb and a filament arranged in the glass bulb and is used for lighting. Incandescent lamps are commonly used bulbs in homes today. After the bulb is used for a period of time, the filament is blown and the bulb needs to be replaced.

When the bulb is replaced, the lamp holder is higher in installation position, a person generally needs to step on a stool, then the lamp holder is held by one hand, the broken bulb is screwed off by the other hand, and then the bulb capable of normally emitting light is screwed on. First, this process has the following problems: 1) when a person steps on the stool, the head is upward, the cervical vertebra is pressed, and the blood supply is insufficient, so that the center of gravity is unstable and the person is easy to fall down; 2) the hands are always upward, the arms are sore and easy to lose hands, so that the bulbs fall off, glass slag is generated, and the bulbs are difficult to clean; 3) when the filament of the bulb is blown, the bulb switch may be in an on or off state, and when the normally luminous bulb is screwed into the lamp holder, the bulb may suddenly light up, which suddenly causes strong light impact to human eyes and is difficult to relieve for a while.

SUMMERY OF THE UTILITY MODEL

To the deficiency of the prior art, the technical problem to be solved by the present patent application is: how to provide a lamp which is convenient for replacing a bulb, can be operated by a single hand, and has the advantages of time saving, labor saving and high safety.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a lamp comprises a mounting seat, a lampshade, an outer lamp holder, an inner lamp holder and an incandescent lamp; the lamp shade is fixedly arranged on the mounting seat, the outer lamp holder is fixedly arranged in the lamp shade, the inner lamp holder is in up-and-down sliding fit in the outer lamp holder, and the inner lamp holder and the outer lamp holder are connected through a sliding mechanism; a conductive inner screw is fixedly installed in the inner lamp holder, an internal thread is arranged in the conductive inner screw, a conductive outer screw is fixedly installed on the outer side of a lamp socket of the incandescent lamp, an external thread matched with the screw in the lead is arranged on the outer side of the conductive outer screw, a first soldering tin contact is arranged at the end part of the lamp socket of the incandescent lamp, a second soldering tin contact is arranged on the inner side of the inner lamp holder, opposite to the first soldering tin contact, the first soldering tin contact is connected with the conductive outer screw through a filament, and the filament is arranged in a glass shell of the incandescent lamp; the lamp comprises an inner lamp holder, an outer lamp holder, a conductive inner screw, a conductive sheet, an insulating sheet and an outer lamp holder, wherein a strip hole penetrates through the inner lamp holder from inside to outside, the outer side of the conductive inner screw is fixedly provided with the conductive sheet, the conductive sheet is fixedly arranged in the strip hole, the insulating sheet is arranged below the conductive sheet in the strip hole, the outer surfaces of the insulating sheet and the conductive sheet are positioned in the same vertical plane, and the outer lamp holder is provided with a conductive elastic sheet over against the strip; and electric wire through holes are formed in the outer lamp holder, the lampshade and the mounting seat in a penetrating manner.
