Abstract

The utility model discloses an LED bulb shell type lamp chain, which mainly comprises a conducting wire, an LED connected to the conducting wire, a plastic bulb shell sheathed outside the LED, water-proof glue filled in the bulb shell, and a heat-shrinkable tube sheathed outside the bulb shell. A resistor is connected in series between the LED and the conducting wire, and the resistor and the LED are sheathed in the plastic bulb shell. The resistor is also sheathed in the plastic bulb shell, the bulb shell is filled with the water-proof glue, and thus the utility model has the advantages of good waterproof property and long service life.

Description

A kind of LED cell-shell formula lamp string

Affiliated technical field

The utility model relates to a kind of decorative chain, especially a kind of LED cell-shell formula lamp string.

Background technology

Existing cell-shell formula lamp string mostly adopts pea lamp to make, not strip resistance, so its caloric value height, and also pea lamp is fragile, and the life-span falls short of.

Summary of the invention

The purpose of this utility model is that a kind of caloric value is low in order to provide, the life-span is long, water proofing property LED cell-shell formula lamp string preferably.

To achieve these goals, the technical solution adopted in the utility model is a kind of LED cell-shell formula lamp string, mainly comprises lead, the LED that is connected with lead, and described LED is equipped with the plastic cement cell-shell outward, be filled with marine glue in the plastic cement cell-shell, the plastic cement cell-shell is equipped with heat-shrinkable T bush outward; Be in series with resistance between described LED and the lead, this resistance and LED all are placed in the plastic cement cell-shell.

The utility model compared with prior art its beneficial effect has: owing to adopted LED, so the utility model caloric value is low, the life-span is long; Because described resistance also is placed in the plastic cement cell-shell, and is filled with marine glue in cell-shell, so good waterproof performance.

Description of drawings

Fig. 1 is an outside drawing of the present utility model;

Fig. 2 is STRUCTURE DECOMPOSITION figure of the present utility model;

Fig. 3 is the STRUCTURE DECOMPOSITION figure that plastic cement cell-shell of the present utility model is a both ends open.

The specific embodiment

Followingly the utility model is further described with reference to accompanying drawing:

With reference to Fig. 1, Fig. 2, the lead-foot-line 31 of LED3 is connected with lead 11, lead-foot-line 32 is connected with resistance 5, the other end of resistance 5 is connected with lead 1, the end of LED3, resistance 5 and lead 1 and 11 is filled in the plastic cement cell-shell 2, plastic cement cell-shell 2 is end openings, and marine glue injected in the cell-shell 2, make LED3, resistance 5, lead 1 and 11 and plastic cement cell-shell 2 fuse, encase with the end of heat-shrinkable T bush 4 then cell-shell 2 and lead 1 and 11, and heat hot Heat-Shrinkable Tubings 4 makes it to tighten, and forms a lamp body 6 like this.Repeat above-mentioned action, form some lamp body series connection of as above being done a string.Again that some strings are such lamp is in parallel to be inserted between lead 1a and the 1b, and lead 1a and 1b are communicated with attaching plug, constitute the utility model like this.In the lamp bar of each series connection, also can only have and contain resistance 5 in some lamp bodies, resistance 5 plays the current limliting dividing potential drop.Because the said structure form makes that the utility model caloric value is low, the life-span is long, and good waterproof performance.

In addition, plastic cement cell-shell described in the utility model also can be the structure of both ends open, and shown in 21 among Fig. 3, one of them openend is bigger than the external diameter of LED3, and another openend is just adaptive with the external diameter of LED3.Head with LED3 when assembling exposes half outside the smaller opening end of plastic cement cell-shell 21, and fills with the marine glue sealing in cell-shell 21 inside.All the other ways are same as shown in Figure 2.

Above illustrated embodiment only with convenient explanation the utility model, is not breaking away from creation spirit scope of the present utility model, is familiar with any simple covert and modification that the personage did of this technology, must be contained in the rights protection scope of the present utility model.

Claims

1, a kind of LED cell-shell formula lamp string mainly comprises lead, the LED that is connected with lead, and it is characterized in that: described LED is equipped with the plastic cement cell-shell outward, is filled with marine glue in the plastic cement cell-shell, and the plastic cement cell-shell is equipped with heat-shrinkable T bush outward; Be in series with resistance between described LED and the lead, this resistance and LED all are placed in the plastic cement cell-shell.
