Description

Can improve the led lamp of radiating efficiency

Technical field

The utility model is about a kind of led lamp, but refers to a kind of light fixture that quick heat radiating when making light emitting diode work is constructed in thermo-contact that sees through especially.

Background technology

In common people's daily life, lighting apparatus is indispensable people's livelihood necessity, because use is general and consumption is big, on the environmental protection subject under discussion of using electricity wisely, is the object that often is raised and examines therefore.With regard to lighting apparatus, the theme of self-criticism is nothing more than illumination efficiency and radiating effect.Wherein illumination efficiency is promptly relevant with the power consumption and the illumination usefulness of equipment, in the at present known light source, light emitting diode is considered to can meet the environmental protection notion, main cause is to possess advantages such as low power consumption and long working life, but be used on the lighting use, single light emitting diode is not sufficient to satisfy the demand of big illumination light fixture, thereby must be with several complete modular form teamworks, and one of advantage of light emitting diode tie up in when work temperature relatively low, in case after the teamwork, the heat dissipation problem of led lamp promptly has to actively face.

Summary of the invention

The purpose of this utility model is to provide a kind of led lamp that improves radiating efficiency, and it can utilize special thermo-contact structure, and the light-emitting diode (LED) module in the light fixture is dispelled the heat when work more efficiently.

The led lamp that improves radiating efficiency of the present utility model is characterized in that comprising:

One heat-conducting seat, this heat-conducting seat have an end face and a bottom surface, and this bottom surface indent forms an accommodation space, are formed with above together outstanding fixed part in the accommodation space, and this fixed part has at least one oblique sidewall;

More than one light-emitting diode (LED) module, the surface that mainly lies in a circuit board is provided with several light emitting diodes, and its bottom surface then sees through heat-conducting glue and is incorporated on the oblique sidewall of fixed part.

The mat said structure, but because of heat-conducting seat and on fixed part system constitute by the heat conductive metal material, so heat abstractor can directly be installed outside heat-conducting seat, the fixed part that light-emitting diode (LED) module then sees through in heat-conducting glue and the heat-conducting seat constitutes good thermo-contact, thereby the heat energy that light-emitting diode (LED) module when work produced waves diffusingly apace via heat-conducting seat, effectively promotes radiating efficiency.

The specific embodiment

About the preferred embodiment of one of the utility model, at first see also Fig. 1 to shown in Figure 4, it comprises a heat-conducting seat 10 and is located at light-emitting diode (LED) module 20 in the heat-conducting seat 10 more than one; Wherein:

In present embodiment, this heat-conducting seat 10 is a rectangular shape and have an end face and a bottom surface, its bottom surface inwardly concaves and forms an accommodation space 11, this accommodation space 11 also has an inner bottom surface 110, be formed with above together outstanding fixed part 12 again on the inner bottom surface 110 of accommodation space 11, in present embodiment, be formed with several fixed part that on a first direction, is arranged in parallel 12 in the accommodation space 11,12 ', each fixed part 12,12 ' is structure as a whole with heat-conducting seat 10, each fixed part 12 again, 12 ' possesses an oblique sidewall 120 at least, 120 ', in the present embodiment, the fixed part 12 ' that is positioned at accommodation space 11 dual-side positions only forms an oblique sidewall 120 ' on the relative inner limit, other fixed part 12 that is positioned between two fixed parts 12 ' then is formed with two relative oblique sidewalls 120, and the oblique sidewall 120 on each fixed part 12 is and adjacent fixed portion 12, oblique sidewall 120 on 12 ', 120 ' constitutes as splay external mutually rake angle.Oblique sidewall 120,120 ' two ends on each fixed part 12,12 ' are formed with a fixing hole 121,121 ' respectively again.

Still please cooperate and consult Fig. 1 to shown in Figure 4, the circuit board 21 that this light-emitting diode (LED) module 20 mainly lies in a narrow and long rectangular shape is provided with several light emitting diodes 22, in present embodiment, each light emitting diode 22 is to be evenly distributed on the outer surface of circuit board 21, the inner surface of circuit board 21 is then corresponding to each fixed part in the heat-conducting seat 10 12,12 ' oblique sidewall 120,120 ', being formed with two fixing holes 210 again on the circuit board 21, is the fixing hole 121,121 ' on respectively corresponding each fixed part 12,12 '.

Each light-emitting diode (LED) module 20 is mounted to the mode on the heat-conducting seat 10 again, elder generation of system is at circuit board 21 inner surfaces and/or heat-conducting seat 10 each fixed part 12 of light-emitting diode (LED) module 20,12 ' oblique sidewall 120,120 ' goes up evenly coating heat-conducting glue, again circuit board 21 is pasted at each fixed part 12 with its inner surface, 12 ' oblique sidewall 120,120 ' goes up and formation thermo-contact (as shown in Figure 3), then for guaranteeing that light-emitting diode (LED) module 20 is combined in fixed part 12 really, 12 ' oblique sidewall 120, on 120 ', further at circuit board 21 and oblique sidewall 120,120 ' goes up corresponding fixing hole 210,121, DRIVE SCREWS (not shown) in 121 ' is to strengthen this light-emitting diode (LED) module 20 at fixed part 12, on 12 ' in conjunction with effect.

As previously mentioned, because heat-conducting seat 10 and on fixed part 12,12 ' be to constitute by heat conductive metal material one, and light-emitting diode (LED) module 20 be with fixed part 12,12 ' on oblique sidewall 120,120 ' directly constitute thermo-contact, when light emitting diode 22 is started working, the heat energy of its generation can directly see through fixed part 12,12 ' and conduct to heat-conducting seat 10, heat-conducting seat 10 then can install heat abstractor additional at its end face and dispel the heat, the heat energy that produces when by this, light-emitting diode (LED) module 20 is worked can be waved diffusing apace.

As shown in Figure 5, the heat abstractor that aforementioned heat-conducting seat 10 end faces install additional can be a radiating seat 30, this radiating seat 30 can be by the extrusion molding of aluminium one, its surface is formed with several fin ribs, have one again and constitute the bottom surface of thermo-contact with heat-conducting seat 10 end faces, in present embodiment, the bottom surface of radiating seat 30 system sees through heat-conducting glue 50 and combines with heat-conducting seat 10 end faces, constitute good heat transfer medium by this, and wave the heat energy that produces when distributing the work of optical diode light fixture fast.
