Abstract

The utility model discloses an LED line lamp which comprises a surface layer insulating metal wire, an LED chip, a transparent colloid and a transparent plastic sleeve, wherein the surface layer insulating metal wire is provided with a flat point with an exposed metal, the LED chip is electrically fixed on the flat point, the transparent colloid is packaged on the LED chip and is used for fixing, and a layer of transparent plastic sleeve is sleeved outside a lamp body. No welding point exists between a luminophor thereof and a connecting body, so that the reliability of a product is enhanced, procedures of single LED package, lamp string welding and the like are avoided, the material loss is reduced and the product cost is saved.

Description

LED line lamp

Affiliated technical field

The utility model relates to the illumination and decoration field, particularly a kind of LED line lamp.

Background technology

The LED bulb is because little, the advantages such as light is soft, rich color, safety and environmental protection of volume, be widely used in ornament lamp field in red-letter day, as flexible lighting product and the LED lamp string that west American-European countries uses Christmas Day, can set off festive air densely after adorning or hanging up.The type lamp string generally links up the weldering of LED bulb with tiny electric wire, can produce light fragmentarily after the energising.Though these lamp string structures and manufacture craft are simpler, be encapsulated into separately from LED and be welded into the lamp string, the middle need through multiple working procedure, during can produce problems such as material consumption increase, failure welding, technology are numerous and diverse, the raising of defective products rate.

Summary of the invention

For addressing the above problem, the utility model provides a kind of simple in structure, safe and reliable LED line lamp.

For achieving the above object, the technical scheme that the utility model adopted is: LED line lamp, comprise top layer insulated metallic filaments, led chip, transparent colloid and transparent plastic cover, the flat spot of revealing metal is arranged on the insulated metallic filaments of top layer, electrically be fixed with led chip on the flat spot, be packaged with transparent colloid on the led chip and fix, the lamp body outside is with the layer of transparent plastic sheath.

Compared with prior art, adopt led chip directly electrically to be fixed on the wire, be packaged with transparent colloid on the led chip and fix, do not had pad between illuminator and the connector, avoided the product problem that opens circuit, can be arbitrarily crooked, improved reliability of products, avoided operations such as independent encapsulation of LED and lamp series welding connect, work simplification, reduce spillage of material, compressed the production time, reduced the social cost of product significantly; The lamp body skin has overlapped the layer of transparent plastic sheath, the effect that can play waterproof and improve bright spot.

Below in conjunction with accompanying drawing the utility model is described further

With reference to Fig. 1,2, LED lamp string in the market generally is made of LED bulb (1), tiny electric wire (2).The LED bulb comprises cathode metal support (3), negative pole metallic support (4), led chip (5), gold thread (6) and epoxy resin (7), led chip (5) is fixed in (4) on the negative pole metallic support, connect encapsulation one deck epoxy resin (7) in outside between led chip (5) and the both positive and negative polarity metallic support (3,4) with gold thread (6).Link up with tiny electric wire (2) weldering between a plurality of LED bulbs (1) and make the lamp string.Owing to adopt between the LED bulb (1) electric wire (2) weldering to link up, pad (8) is easy to generate false problem such as weld, get rusty, thereby influences the quality problems of product; Be encapsulated into separately from LED bulb (1) and make the lamp string, during need through multiple working procedure, spillage of material increases, and is unfavorable for the reduction of product cost.

With reference to Fig. 3,4,5, the utility model provides a kind of embodiment, form by top layer insulated metallic filaments (9), led chip (5), epoxy resin (7) and transparent plastic cover (11), it is characterized in that the flat spot (10) of revealing metal is arranged on the insulated metallic filaments (9), led chip (5) electrically is fixed on the flat spot (10), led chip (5) and flat spot (10) skin are packaged with epoxy resin (7) to be fixed, and the lamp body skin is with layer of transparent plastic sheath (11), thereby makes LED line lamp.This lamp does not have pad (8), directly uses the flat spot (10) on epoxy resin (7) encapsulation fixed L ED chip (5) and the insulated metallic filaments, has improved reliability of products significantly; Simplify operation simultaneously, reduced spillage of material, helped saving the social cost of product; The lamp body skin has overlapped layer of transparent plastic sheath (11), the effect that can play waterproof and improve bright spot.

The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model, and promptly all equalizations of being done according to the utility model claim change and modify, and are all claim of the present utility model and contain.
