Description

A kind of all-round luminous LED lamp

Technical field

The utility model relates to a kind of LED lamp with all-round illumination effect.

Background technology

LED light source has obvious directionality, is therefore forming general illumination light fixture, during especially for alternative all-round luminous traditional bulb lamp, must process its luminous beam, makes it beam angle and is increased.The all-round smooth LED bubble lamp of prior art, be generally to realize by opticses such as reflectors, but the whole light beam of this scheme is difficult to adjustment evenly, and its light beam projecting exists the hot spot that light and shade contrast is larger, and particularly dark space, cell-shell top is more obvious.

Utility model content

For the existing problem that the adjustment of the LED beam of light is inhomogeneous, cell-shell top exists dark space that realizes all-round light with optics, the utility model proposes a kind of all-round luminous LED lamp, its technical scheme is as follows:

A luminous LED lamp, it comprises:

One fixing body, its form is the polyhedron shrinking gradually from bottom to top, its side comprises the installed surface that the width of circumferential distribution diminishes gradually from bottom to top;

One radiator, thermal conductance is led in described fixing body, has and is exposed to airborne radiating surface; And

Some light source substrates, are fixed one by one in described installed surface, and its size shape is suitable with place installed surface; The surface distributed fixed L ED chip of this light source substrate; Wherein said LED chip and described light source substrate, fixing body and radiator form thermal conducting path.

This programme can have following improvement:

In better embodiment, the structure that described fixing body and radiator are formed in one.

Better, in embodiment, described installed surface is isosceles trapezoid or leg-of-mutton form.

Better, in embodiment, described installed surface has four, and Rotational Symmetry distributes.

Better, in embodiment, cover a cell-shell on described fixing body, this cell-shell and described radiator fix; This radiator is fixed a lamp holder with respect to the other end of this cell-shell; This radiator has the lamp housing of an insulation in it, the driver of light source substrate described in fixed drive in this lamp housing; Described driver, light source substrate and lamp holder all have electrical connection.

The beneficial effect of this programme has:

1. the light of light source substrate not only has the component of horizontal all-round illumination effect, and its cell-shell top also has obvious component, and this structure is resolved the problem of dark space, cell-shell top,, in its vertical space, is evenly distributed meanwhile.

2. whole lamp part project organization is simple, and cost is than low on existing market, high conformity.

Accompanying drawing explanation

Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:

Fig. 1 is the critical piece explosive view of the utility model one embodiment;

Fig. 2 is axle section embodiment illustrated in fig. 1 and with the schematic diagram of its distribution of light.

The specific embodiment

As depicted in figs. 1 and 2, the schematic diagram of the utility model one embodiment, wherein Fig. 1 has shown its critical piece; Fig. 2 is a profile of its duty.

The present embodiment, a kind of all-round luminous LED lamp, it comprises a fixing body 10, and these fixing body 10 its forms are the polyhedron shrinking gradually from bottom to top, and the lower of the present embodiment is the direction of lamp holder 70, is above the direction of cell-shell 40.The side of fixing body 10 comprises installed surface 11, and these installed surfaces 11 circumferentially distribute, and width separately diminishes to form the structure of contraction from bottom to top gradually.One radiator 20, has good thermal conductance path with fixing body 10, and has and be exposed to airborne radiating surface 21.

On each installed surface 11, all fixed a light source substrate 30, and light source substrate 30 matches with installed surface 11, the installed surface 11 at its size shape and place is suitable.The surface distributed fixed L ED chip 31 of this light source substrate 30; Wherein, LED chip 31 forms thermal conducting path with light source substrate 30, fixing body 10 and radiator 20.

As shown in Figure 2, under this structure, the luminous schematic diagram of the present embodiment, its light as shown by arrows, not only all has to both sides, top in figure the component that forms all-round illumination effect from the light of light source substrate 30 on fixing body 10, it is in Fig. 2 direction down, also be that cell-shell 40 tops also have obvious component, so, this structure make cell-shell 40 tops (under) problem of dark space is resolved, meanwhile, in its vertical space, be evenly distributed.

The present embodiment also has some other feature:

Fixing body 10 and the structure that radiator 20 is formed in one, simplified the quantity of global facility, keeps good mechanical strength, high conformity simultaneously; The form that installed surface 11 is isosceles trapezoid, makes light source substrate 30 can realize symmetrical structure when axial distribution.Especially, the present embodiment installed surface 11 has four, and Rotational Symmetry distributes, and under installed surface 11 prerequisites of minimum number, has realized circumferentially the most uniform illumination effect.

Cell-shell 40 covers on fixing body 10, and fixes with radiator 20, makes the light distance of fixing body 10 arrival cell-shell 40 inner surfaces suitable, realizes the brightness vision effect of cell-shell 40 surface uniforms; Radiator 20 is with respect to the fixing lamp holder 70 of the other end of this cell-shell 40; This radiator 20 has the lamp housing 50 of an insulation, the driver 50 of the interior fixed drive light source substrate 30 of this lamp housing 50 in it; Driver 50, light source substrate 31 and lamp holder 70 all have electrical connection.This structure is applicable to realize the light fixture of small diameter cell-shell 40, for example the dimensions of G45 type bulb.

The above, it is only the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of doing according to the utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that the utility model contains.
