Abstract

The utility model provides an LED (Light-Emitting Diode) lamp, comprising a lamp bracket and a plastic lamp holder molded on the lamp bracket, wherein an LED lamp body is located in the plastic lamp holder; the whole body of the lamp bracket is in an inward concave structure; the side wall of the lamp bracket is in a straight and vertical structure; preferably, the height of the side wall of the bottom of the lamp bracket is 0.05 mm; and the shapes of the residual walls except the bottom of the lamp bracket are in an arc surface shape. The size of the bottom of the lamp bracket is the same so that the molded shape of the plastic lamp holder is uniform and stable, and the uniformity and the consistency of the shape of the LED lamp body and outgoing lights are further guaranteed; the light-emitting effect of the LED lamp is consistent and the light-emitting refraction rate and the light-emitting lumen value of the LED lamp can be improved; and the light-emitting brightness of the LED lamp is higher and the finished product rate is obviously improved on the premise that the cost is not increased.

Description

A kind of LED lamp

Technical field

The utility model relates to a kind of LED lamp, relates in particular to the improvement to the LED lamp support in the LED lamp.

Background technology

The LED(light emitting diode) becomes gradually the mainstream development trend of lighting field with its good luminescent properties.Common LED lamp generally is by at the upper forming plastic cement lamp socket of lamp support (being generally copper product makes), fixes or interior edge LED circuit for lamp in the plastic lamp holder, and the LED lamp body that the circuit of LED lamp and lamp support are electrically connected in the rear drive plastic lamp holder is luminous.In the existing LED lamp, lamp support 1 totally is concave shape, is molded over plastic lamp holder 2 on the lamp support mostly for cup-shaped design, and wall of cup 10 generally is inclined design, and as shown in Figure 1, like this, the beam projecting direction of LED lamp often and disunity, stable; On the other hand, because lamp support generally is array-like and produces by batch, the size of support, plastic lamp holder position at the bottom of being positioned at glass is difficult in full accord, like this, the shape that is molded over the LED lamp body in the plastic lamp holder is disunity also, thereby causes non-uniform light after the LED lamp body energising in the plastic lamp holder, and the refractive index of LED light and flow valuve are bright not high, cause the defective products rate of product higher, can't guarantee the quality of product.

Summary of the invention

The purpose of this utility model provides a kind of LED lamp, is intended to solve not of uniform size the causing at the bottom of the plastic lamp holder cup of existing LED lamp, the technological deficiency that the refractive index that the LED lamp is luminous and luminous lumen value are not high.

For achieving the above object, a kind of LED lamp that the utility model provides comprises lamp support and the plastic lamp holder that is molded on the lamp support, and the LED lamp body is positioned at plastic lamp holder, it is characterized in that: described lamp support totally is concave inward structure, and the sidewall of lamp support bottom is rising structure.

More specifically, the sidewall height of described lamp support bottom is between the 0.03-0.07mm, highly is 0.05mm preferably.

More specifically, described lamp support all the other sidewall shape except the bottom are arc surfaced.

Adopt the LED lamp of said structure, because the shape of lamp support is improved, especially be designed with a downward structure of directly stretching in frame bottom, when the lamp support punch forming, be easy to make size, the bottom shape that shape is consistent, because plastic lamp holder just is molded in this lamp support, therefore be easy to guarantee that the unification of forming shape of plastic lamp holder is with stable, and then the shape of assurance LED lamp body, emergent ray evenly, unanimously, the illumination effect of guaranteeing the LED lamp is consistent, has improved luminous refractive index and the lumen value of LED lamp integral body, makes the luminosity of LED lamp higher, guarantee LED characteristic of a navigation light amount stability, reduced the defective products rate.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

Shown in Fig. 2, Fig. 3, Fig. 4, the LED lamp that the utility model preferred embodiment provides comprises the lamp support 1 that copper coin is made, and be molded over plastic lamp base 2 on the lamp support 1, LED lamp body (not shown) is positioned at plastic lamp holder 2 in due form, during actual fabrication, a plurality of plastic lamp bases 2 form array-like together with lamp support 1, so that the LED lamp that is placed in one also forms LED lamp array.

The lamp support of the utility model LED lamp totally is concave inward structure, and the sidewall 13 of lamp support bottom is rising structure.Rely on this upright bottom sidewall to form the downward structure of directly stretching, like this, take shape in this and directly stretch plastic lamp base 2 in the structure, more easily locate and definite its shape, when batch production, plastic lamp base 2 also can be evenly, unanimously together with the shape of LED lamp body, the emergent ray angle of LED lamp more easily reaches designing requirement, and namely the structure of directly stretching of the same size can guarantee that the illumination effect of LED lamp is consistent, thereby guaranteed LED characteristic of a navigation light amount stability, reduced the defective products rate.And these improvement only need to increase one and directly stretch corresponding protruding the getting final product of structure bottom lamp support in the mould structure design of moulding lamp support, need not to improve any cost of manufacture of lamp support.

More specifically, the sidewall 13 of described lamp support bottom highly is between the 0.03-0.07mm, preferred highly is 0.05mm, the utility model is specially adapted to the making of comparatively small LED lamp, the height of sidewall 13 generally should not be too dark, otherwise can affect the intensity of lamp support, but the too shallow typing that also is unfavorable for plastic lamp base 2 of the height of sidewall 13.

More specifically, described lamp support all the other sidewall 12 shapes except the bottom are arc surfaced.As shown in Figure 2, so-called " all the other sidewalls except the bottom " refer in the rack side wall of concave shape, is positioned at all the other sidewalls outside the sidewall of bottom, do not comprise the bottom surface.The purpose of design is so that the emergent ray of LED lamp body can radiate comprehensively like this, further improves luminous refractive index and the luminous lumen value of LED lamp, makes the luminosity of LED lamp higher, guarantees the service behaviour of LED lamp.
