In Straight LED in the past, have and can not form a point problem for the lamp holder of half structure in precision highland.
That is, due in the lamp holder that inserts in the end for housing, can not carry out screw fix in the position of inserting for this housing, the position that therefore screw is fixed becomes the position of the leading section of deflection lamp holder., two balance of plant Floor screws of the main body forming lamp holder can not be fixed for this reason, therefore can not form this lamp holder in precision highland.Thus, produce such as the following problem: lamp holder precision highland can not be fixed on housing, or produce gap thus the light of LED is revealed from this gap between two parts of main body forming lamp holder, or dust enters from this gap.
The present invention completes to solve such problem, and its 3rd object is, provides and can form a point lamp for the lamp holder of half structure in precision highland.
In order to reach above-mentioned 3rd object, a mode of the 3rd lamp involved in the present invention is the lamp that a kind of socket via being arranged on ligthing paraphernalia is arranged on described ligthing paraphernalia, possesses: the housing of microscler shape, is provided with semiconductor light-emitting elements in inner side; Connecting portion, be arranged on end on the length direction of described housing and leading section is releasably connected with described socket, described connecting portion possesses the first main part and the second main part that are mutually fitted together to thus form the main body of described connecting portion, described first main part has from the different multiple juts of the distance on described length direction of the end of described housing, described second main part have with on each corresponding position of described multiple jut with each chimeric multiple fitting portion of described multiple jut.
Accordingly, the standby connecting portion as lamp holder of light fixture, this connecting portion possesses the first main part by chimeric formation main body and the second main part, first main part has the different multiple juts of the distance in the longitudinal direction of the end of the housing from microscler shape, and the second main part has each the chimeric multiple fitting portion with multiple jut.That is, screw is not carried out to fix and the plurality of jut and the plurality of fitting portion are fitted together to, thus form the main body of the first main part and the second main part formation, therefore have nothing to do with the position of the housing be inserted into, the first main part and the second main part can be fixed evenly.Thereby, it is possible to precision highland forms a point lamp holder for half structure.
In addition, in a mode of the 3rd lamp involved in the present invention, preferably described first main part has the first coincidence part, when described multiple jut and described multiple fitting portion are fitted together to, this this first coincidence part overlaps with described second main part with the mode in the gap of described second main part with obturation, described second main part has the second coincidence part, when described multiple jut and described multiple fitting portion are fitted together to, this second coincidence part overlaps with described first coincidence part with the mode in the gap of described first main part with obturation.
Accordingly, when multiple jut of the first main part and the second main part and multiple fitting portion chimeric, the first coincidence part and the second coincidence part overlap to make gap disappear.That is, the first main part and the second main part overlap and are fitted together to, therefore, it is possible to prevent from producing gap between the first main part and the second main part.Thereby, it is possible to prevent the light of LED from revealing between the first main part and the second main part, or dust, worm etc. enter.
In addition, in a mode of the 3rd lamp involved in the present invention, preferred described multiple jut is fitted together to described multiple fitting portion from the inner side of described second main part.
