Preferably, described printing opacity cell-shell comprise the top cone and with the open column shape body of top cone one.

Preferably, the openend of described printing opacity cell-shell is equipped with the seal of a sealed cavity.

Preferably, be provided with a separator between the lamp base of described LED, described separator is positioned at the below of seal, and described separator is isolated lamp base and the partially conductive line of LED.

Preferably, described seal and separator are one machine-shaping.

Preferably, described seal is a tail plug, and described tail plug is provided with the jack that the lamp base with LED is complementary, and the lamp base of described LED passes jack and is electrically connected with conductor wire.

Preferably, the tail end of described tail plug is provided with a thrust plate, and described thrust plate contacts with the openend of printing opacity cell-shell.

Preferably, described seal is an end cover that is complementary with the afterbody of printing opacity cell-shell, and the bottom of described end cover is provided with the through hole that the lamp base with LED is complementary, and the lamp base of described LED passes through hole and is electrically connected with conductor wire.

The utility model adopts the lamp socket of injection molding type fundamentally to solve the waterproof problem of lamp holder, make the lamp string stand the erosion of rainwater for a long time out of doors and can not leak, leak electricity, in addition because lamp socket adopts the mode of beer notes to make, its tensile strength is far above combined type lamp holder of the prior art, and therefore lamp holder of the present utility model can normally use under various adverse circumstances.

The specific embodiment

In order to further specify the utility model structure, be described in detail below in conjunction with accompanying drawing.

As Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7: the holder structure that the utility model discloses a kind of injection molding type lamp string, comprise printing opacity cell-shell 2, one cavity 20 is set in the described cell-shell, and described cavity 20 comprises inwardly protruded top 21, columniform sidewall 22 and opening 23; Be placed on the LED1 in the described cavity 20, LED1 comprises lamp holder 11 and lamp base 1a, 1b; Lamp base 1a, the 1b of described LED is electrically connected with conductor wire 3, and the afterbody injection moulding of printing opacity cell-shell 2 forms a lamp socket 4, and described lamp socket 4 coats the afterbody and the partially conductive line 3 of printing opacity cell-shell 2.Because top 21 inwardly protrudings of cavity 20 can play the effect of optically focused, therefore when lighting, lamp holder can form another bright spot at the top 21 of printing opacity cell-shell 2, the utility model utilizes the special construction of cavity 20 to realize adopting the effect of the lamp holder simulated dual bright spot of single LEDs, compares traditional holder structure and has more ornamental.
