Description

The heat-conducting substrate of high power lighting lamp

Technical field

This utility model is related to a kind of illuminations, particularly to a kind of heat-conducting substrate of high power lighting lamp.

Background technology

Led illuminating lamp have the characteristics that energy-conservation, can high-power light-emitting, its be widely used in various illuminating lamps use. However, implementing to beat power illumination using led luminous body, it can produce larger heat, if this heat removing not in time, a side Face can impact to led luminous body, on the other hand the wiring board that control led luminous body can be impacted, and leads to led to light The service life of body and wiring board shortens.At present, traditional heat-dissipating mode market and data occurring is as follows: sets on radiating seat Put wiring board, the installation place that wiring board is located at led luminous body is provided with through hole, and radiating seat mountain is provided through the heating column of through hole, led Luminous body is passed through heat sink plate and is welded with this heating column.Such radiating mode heat-conducting area is little, and heat-transfer rate and radiating rate are relatively Slowly, led luminous body thereon and wiring board are easily overheated impaired.

Content of the invention

In view of the shortcomings of the prior art, this utility model provides that a kind of heat-transfer rate is fast, heat transfer area big, structure The heat-conducting substrate of simple high power lighting lamp.

For achieving the above object, this utility model provides a kind of following technical scheme: the heat conduction base of high power lighting lamp Plate it is characterised in that: include heat conduction plate body, one end of heat conduction plate body is conduction of heat face, and the other end is to connect for led luminous body Connection plane.

Using technique scheme, the conduction of heat face on heat conduction plate body can be implemented face with radiating seat and be contacted, when heat conduction plate body On have outside heat when, quickly can transfer heat to radiating seat, so that this heat is quickly removed；Heat-conducting plate The connection plane of body is then used for installing led luminous body, and the heat that led luminous body produces quickly can be absorbed by heat conduction plate body and pass Pass, so not only heat transfer area is big for setting, and heat conduction and radiating rate are very fast.

This utility model is further arranged to: the connection plane of heat conduction plate body is provided with several mounting grooves, each mounting groove Between there is the heat conduction convex tendon of heat sink plate weld for led luminous body.

Using technique scheme, the setting of heat conduction convex tendon can be easy to led luminous body and be connected with the enforcement of heat conduction plate body, and each Between heat conduction convex tendon mounting groove be disposed to place insulation board, make between each led luminous body electrical connection, but can avoid mutually The situation of interference, prevents led luminous body from short circuit.

This utility model is further arranged to: heat conduction convex tendon is in step-like setting.

Using technique scheme, after led luminous body is installed on heat conduction convex tendon, because heat conduction convex tendon is in step-like setting Put, isolation channel therefore between led luminous body and the bottom of mounting groove, can be formed, be so disposed to further to prevent short Road.

This utility model is further set to: heat conduction plate body is cuboid, and described mounting groove is vertical along heat conduction plate body To arrangement, and heat conduction plate body is up to provided with row's mounting groove less.

Using technique scheme, so setting promotes the space on heat conduction plate body to be reasonably utilized.

This utility model is further set to: conduction of heat face be cambered surface or plane or some sections pass through fillet or chamfering rank The thermal conductive surface connecing.

Using such scheme, good heat conduction effect is so set, radiating rate is fast.

Below in conjunction with the accompanying drawings this utility model is further described.

Specific embodiment

A kind of heat-conducting substrate of the high power lighting lamp as shown in Fig. 1 Fig. 3, includes heat conduction plate body 1, heat conduction plate body 1 One end be conduction of heat face 11, the other end be for led luminous body connect joint face 12.In such scheme, on heat conduction plate body 1 Conduction of heat face 11 can be implemented face with radiating seat and be contacted, and when having the heat of outside on heat conduction plate body 1, quickly can pass heat Pass radiating seat, so that this heat is quickly removed；The connection plane 12 of heat conduction plate body 1 is then used for installing led luminous body, The heat that led luminous body produces quickly can be absorbed by heat conduction plate body 1 and transmit, and so not only heat transfer area is big for setting, and Heat conduction and radiating rate are very fast.

In this utility model embodiment 1, the connection plane 12 of heat conduction plate body 1 is provided with several mounting grooves 121, each peace There is between tankage 121 the heat conduction convex tendon 13 of the heat sink plate weld for led luminous body.The setting of heat conduction convex tendon 13 can be easy to led Luminous body and heat conduction plate body 1 are implemented to be connected, and between each heat conduction convex tendon 13 mounting groove 121 be disposed to placement insulation board, Make electrical connection between each led luminous body, but situation about interfering with each other can be avoided, prevent led luminous body from short circuit occurring.As Fig. 2 institute Show, in this utility model embodiment 1, mounting groove 121 is the cavity being on heat conduction plate body 1, and its one end has opening, another End has bottom end face；As shown in figure 3, in this utility model embodiment 2, mounting groove 121 is to observe leading to of heat conduction plate body 1 Hole, so setting save the material of heat conduction plate body 1, have saved production cost.

In this utility model embodiment, in order to prevent the led luminous body being installed on heat conduction plate body 1 from short circuit occurring, lead Hot convex tendon 13 is in step-like setting.After led luminous body is installed on heat conduction convex tendon 13, because heat conduction convex tendon 13 is in step-like setting Put, therefore can form isolation channel 131 between the bottom of led luminous body and mounting groove 121, should be in step-like setting by heat conduction convex tendon 13 The isolation channel 131 putting formation can prevent the short circuit of led luminous body.

Heat conduction plate body 1 in this utility model embodiment be cuboid, mounting groove 121 along the longitudinal arrangement of heat conduction plate body 1, And at least provided with row's mounting groove 121 on heat conduction plate body 1.So reasonably make use of the space on heat conduction plate body 1.Certainly, need It is noted that heat conduction plate body 1 is alternatively circular or triangle, depending on concrete shape can be according to design or needs.

It should be noted that in this utility model embodiment 1 and 2, in order to accelerate the heat-transfer rate of heat conduction plate body 1, leading The conduction of heat face 11 of hot plate body 1 can be cambered surface or plane or some sections of thermal conductive surfaces by fillet or chamfering linking.
