The utility model discloses an LED light having a plurality of chips connected in parallel. The LED light having the chips connected in parallel includes an LED support and at least two small-size LED chips. The LED support includes an insulation base and a metal support fixed by the insulation base. The insulation base is provided with an accommodation concave cavity. The metal support includes a positive conducting terminal and a negative conducting terminal. The two small-size LED chips are arranged on the metal support fixedly and are disposed in the accommodation concave cavity. The two small-size LED chip are connected in parallel and are connected between the positive conducting terminal and the negative conducting terminal in a conducting manner. Thus, by arranging the at least two small-size LED chips to connect in parallel, a chip cost can be reduced effectively in a condition of guaranteeing the luminance of the LED light, and the manufacturing and producing cost of the LED light having the chips connected in parallel is reduced. Moreover, a production speed of adopting the small-size LED chips for manufacturing the LED light is higher than a speed of adopting large-size LED chips for manufacturing the LED chips. Thus, the production efficiency of the LED light having the chips connected in parallel is improved effectively, and the working hour consumption is reduced, thereby improving the productivity of the LED light having the chips connected in parallel fundamentally.

Multicore sheet tandem type LED lamp

Technical field

The utility model relates to LED lamp art, refers in particular to a kind of multicore sheet tandem type LED lamp.

Background technology

At present; Development along with lighting technology; Shortcoming is replaced by the LED lamp traditional incandescent lamp just gradually because highly energy-consuming, photoelectric conversion rate be low etc.; Compare with traditional incandescent lamp, the LED light fixture has that energy consumption is little, spotlight effect is good, reaction speed is fast, can bear advantages such as high impact forces, long service life, environmental protection.

The concrete structure of the LED lamp of conventional known has generally comprised led support and led chip; The metallic support that this led support includes insulating base and fixed by this insulating base; This insulating base is provided with ccontaining cavity; This chip is fixedly arranged on the metallic support and is accommodated in the ccontaining cavity of insulating base; For the light that the LED lamp is sent brighter; The lumen value is higher; Usually, the manufacturing of LED lamp adopts a large scale led chip in producing; This large scale led chip is fixedly arranged on the metallic support, and this large scale led chip conducting is connected between the anodal conducting terminal and negative pole conducting terminal of metallic support.

Above-mentioned existing LED modulated structure; Improve LED lamp lumen value though can offer the user, make the effect that the LED lamp is brighter to have progressive really; But, reality but finds still to have many deficiencies on himself structure and the serviceability when using; Cause existing LED lamp in practical application, fail to reach best result of use and task performance, its shortcoming is summarized as follows at present:

At first,, can not effectively practice thrift chip cost, improve the manufacturing production cost of product, and its speed of production is slow when adopting high-power chip to make the LED lamp, expends more man-hour, makes that the production capacity of LED lamp is lower because large scale led chip price is more expensive.

Secondly,, occupied the bigger space of led support, the ejaculation of light has been impacted, thereby cause the lumen value of LED lamp effectively not improve because the volume of large scale led chip is bigger.

The utility model content

In view of this, the utility model is to the disappearance of prior art existence, and its main purpose provides a kind of multicore sheet tandem type LED lamp, and it can effectively solve existing LED lamp and make the problem that production cost is high, production capacity is low.

Another purpose of the utility model provides a kind of multicore sheet tandem type LED lamp, and it can effectively solve the problem that existing LED lamp lumen value can not effectively be improved.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

A kind of multicore sheet tandem type LED lamp; Include led support and at least two small size led chips; This led support includes insulating base and by the fixing metallic support of this insulating base, this insulating base is provided with ccontaining cavity, and this metallic support includes anodal conducting terminal and negative pole conducting terminal; This two small sizes led chip is fixedly arranged on the metallic support and is placed in the ccontaining cavity, and this two small sizes led chip is connected in series and conducting is connected between anodal conducting terminal and the negative pole conducting terminal.

As a kind of preferred version, said each conducting terminal includes the connecting portion and that stretches in the ccontaining cavity and stretches out the outer weld part of insulating base, and aforementioned two small size led chips are fixedly arranged on the connecting portion of same conducting terminal.

As a kind of preferred version, said two small size led chips are connected in series through gold thread and are connected between anodal conducting terminal and the negative pole conducting terminal through the gold thread conducting.

The utility model compared with prior art has tangible advantage and beneficial effect, particularly, can be known by technique scheme:

One, replaced one of a tradition large scale led chip through utilizing at least two small size led chips to be connected in series; Make guaranteeing effectively to practice thrift chip cost under the luminous bright condition of LED lamp, reduced the manufacturing production cost of product, and; Speed of production when adopting the small size led chip to make the LED lamp is faster than the speed of production that adopts the large scale led chip; Can effectively improve production efficiency of products, that reduces work hours expends, and fundamentally improves the production capacity of LED lamp.

Two, replaced one of a tradition large scale led chip through utilizing at least two small size led chips to be connected in series; The space effective that makes led chip occupy led support reduces; Make the ejaculation of light more smooth; The real lumen value of LED lamp that makes effectively obtains improving, thereby makes the luminous brighter of LED lamp.
