Background technology

Light emitting diode (Light Emitting Diode, LED) be a kind ofly to utilize mutually combining of electronics electricity hole that energy is released the semiconductor subassembly of sending out with the light form, because it is luminous to belong to cold light, have that volume is little, the life-span is long, power consumption is low, reaction rate is fast, the special advantage such as good of vibration strength, except can luminescence component as electric product, more can be extensively as the luminescence component of lighting.

Therefore in the streets promptly have many light-emitting diode lighting modules that are applied to take off lighting; As shown in Figure 1, be a kind of commonly seeing and use the lamp post structure schematic diagram of light-emitting diode lighting module, this street lamp mainly has a lighting module 20 that is equiped with a plurality of light-emitting diodes at lampshade 11 interior constructions; Its lighting module of commonly using mainly utilizes one to have the hard RF-4 printed circuit board (PCB) 21 of conducting function as being the support plate that carries light emitting diode 22.

Because general RF-4 printed circuit board (PCB) is inflexibility, make all light emitting diodes 22 of integral illumination module be merely able to arrange in the mode of identical flat face, not only applicability is lower, and effectively the light source of all light emitting diodes 22 is concentrated, therefore the projection effect of light is also desirable not as expection, especially general hard printed circuit board 21 does not possess any cooling mechanism, can't cooperate the thermal source that light emitting diode 22 is produced to disengage, cause the temperature overheating of integral illumination light fixture, and then influence the service life of lighting.

The utility model content

In view of this, technical problem to be solved in the utility model, promptly improved, aim to provide and a kind ofly have preferable heat dissipation at the lighting module structure in the middle of the lighting, and lighting and lighting module structure thereof with preferable light source projects effect.

Take off purpose on reaching, the technical solution of the utility model is that lighting module is made of a support plate and at least one light emitting diode; As for, support plate is a base material by a pliability bottom, and on the pliability bottom, be provided with heat conductive insulating layer and conductive layer in regular turn, each light emitting diode promptly is built on the conductive layer of support plate, see through conductive layer and power turn-on, in order to do lighting module being cooperated multi-form lampshade bending configuration, to obtain preferable light source projects effect, and utilize the heat conductive insulating layer that the thermal source that light emitting diode produced is directly disengaged through lampshade, to increase the radiating efficiency of integral illumination light fixture.

One of the beneficial effects of the utility model are to utilize soft support plate to cooperate structure bendings such as the lampshade of multi-form lighting or lamp bracket, can active set in the light source of light emitting diode, therefore have preferable ray cast effect.

Two of the beneficial effects of the utility model are that the integral illumination light fixture can conduct to lampshade with thermal source that light emitting diode produces release through the heat conductive insulating layer of support plate and discharge, and therefore have preferable heat dissipation.

The specific embodiment

Characteristics of the present utility model can be consulted the detailed description of the graphic and embodiment of this case and obtained to be well understood to.

Shown in Fig. 2 A, lighting of the present utility model has a lighting module 30 that uses light emitting diode 31 at a lampshade 11 interior constructions, and this lighting module 30 is made of a support plate 32 and at least one light emitting diode 31 basically; Please cooperate simultaneously with reference to shown in Figure 3, this support plate 32 is a base material by a pliability bottom 321, be a soft carrying board structure, and on pliability bottom 321, be provided with heat conductive insulating layer 323 and conductive layer 322 in regular turn, each light emitting diode 31 promptly is built on the conductive layer 322 of support plate 32, and the thickness of this pliability bottom 321 is less than or equal to 0.2mm.

When implementing, pliability bottom 321 can be by aluminium, copper, iron, the made soft structure of stainless steel and other metal materials; As for, conductive layer 322 can be comprehensively or the part be bedded on the heat conductive insulating layer 323, it has the circuit 3221 based on copper, and between circuit 3221, be provided with the insulation division 3222 that constitutes by insulating materials and supply light emitting diode 31 fixations, 311 cooperations of the lead of light emitting diode 31 continue to circuit 3221 places of conductive layer 32, and form with circuit 3221 and to electrically connect, allow to see through conductive layer 322 and power turn-on.
