Description
Technical field
The present invention relates to a kind of lamps.
Background technology
Currently known lamp cap is appropriate only for a kind of lamp holder.For example, it is suitably connected to E27 Edison's lamps without available
Seat and E40 Edison bases and/or it is suitable for the lamp cap being incorporated in E27 Edison bases and E40 Edison bases.In order to
The more flexible lamp for matching the different market demands is provided, it is expected a kind of adjustable lamp cap.
Invention content
It is an object of the present invention to provide a kind of lamps for being suitable for different lamp holders.
The purpose is to utilize to be solved according to the lamp described in independent claims.Preferred embodiment will by appurtenance
It asks, the description and the appended drawings provide.
Correspondingly, a kind of lamp is provided, which includes illumination portion and the lamp cap for lamp to be connect with lamp holder.Lamp cap has
The second lamp for the first lamp head for connecting the lamp with the first lamp holder and for the lamp to be connect with the second lamp holder
Head.First lamp head is between the illumination portion and second lamp head.
Therefore lamp described herein can be placed in the first lamp holder and the second lamp holder.First lamp holder and the second lamp holder can be with
It is different lamp holders.For example, the first lamp holder can be bigger than the second lamp holder.Particularly, the first lamp head can be assembled to the first lamp
In seat, the second lamp head can be assembled in the second lamp holder.This design of lamp cap allows the different demands for meeting user.Cause
This, the switching between different lamp holders can need not change lamp cap and/or using tool.Preferably, burner design is into causing without right
Illumination portion and/or lamp cap carry out size change.Therefore, which allows to provide the multifunctional headlamp with cramped construction,
Without dramatically increasing manufacture cost.
Preferably, the main shaft of lamp corresponds to the principal spread direction of lamp.First lamp head, the second lamp head and illumination portion can
With along main shaft arranged in succession.Lamp cap may be adapted to be electrically connected and/or be mechanically connected with lamp holder.Therefore lamp cap can be incorporated in lamp
In seat.Particularly, the first lamp head and the second lamp head may be adapted to respectively with the first lamp holder and the second lamp holder is electrically connected and/or machine
Tool connects.
According at least one embodiment of lamp, the first lamp head has first diameter, and the second lamp head has second diameter.
Herein and hereinafter, " diameter " can be maximum extension of the various pieces on the direction perpendicular to main shaft.Particularly,
Diameter can be the outer diameter of various pieces.Therefore, the first lamp head can be implemented as thicker than the second lamp head.Lamp holder therefore can be with
Attenuate since the first lamp holder towards the direction of the second lamp holder.
According to preferred embodiment, the first lamp head and/or the second lamp head of lamp are cylindrical.Particularly, lamp
