Abstract

The utility model relates to a heat dissipating module for an LED (light emitting diode) street lamp. The heat dissipating module comprises a radiating fin body and is characterized in that heat conducting pillar components with triangular cross sections are distributed on the radiating fin body in an arrayed way. In addition, heat conducting areas are distributed among the heat conducting pillar components. Due to the heat dissipating module, the air convection current effect and integral heat dissipating area are greatly increased by relying on the coordination among the heat conducting pillar components and the heat conducting areas, the working heat dissipation of the LED street lamp is facilitated, the service life of the street lamp is prolonged, and the heat dissipating module is worth popularizing.

Description

LED street lamp radiating subassembly

Technical field

The utility model relates to a kind of radiating subassembly, relates in particular to a kind of LED street lamp radiating subassembly.

Background technology

Just at present, the LED lighting is the general designation of LED light fixture, and along with the further maturation of LED technology, LED will obtain more better development in the lighting field of designing and developing, room.The room Design of Luminaires of 21 century will be to be main flow with the LED Design of Luminaires, demonstrates fully the illumination development trend of energy-conservationization, healthization, art up and hommization simultaneously, becomes the leading of room light culture.In new century, the LED lighting will illuminate everyone room, changes everyone life, becomes the once great of light fixture development and Design and changes.

The LED light fixture amasss little light weight, can select for use different photochromic LED to be combined into the soft various modules of illumination, is installed in arbitrarily in the room, and the light source of room lighting may derive from ground, metope, windowsill, furniture, jewelry etc.Therefore, the illumination of following room will no longer be confined to single light fixture, and will be converted into the shadowless lamp of the integral illumination effect of no luminaire tool sense by single lamp lighting.Different photochromic and brightness can produce different influences to people's physiology with psychology, and people do not need very bright white light under many circumstances, and the light of possible gold-tinted or other color is more suitable for the needs of physiology and psychology.Three-primary color LED can be realized the continuous transformation and the selection of brightness, gray scale, color, makes illumination expand to the light of multiple color from the white light on the universal significance.

But present LED street lamp can produce bigger heat in work, need effective dissipation that preferable structure is carried out heat, not so influences the work of LED street lamp easily, shortens its service life.

The utility model content

The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of LED street lamp radiating subassembly is provided.

Be to realize the purpose of this utility model, the LED street lamp includes heat sink body with radiating subassembly, and wherein: to be distributed with cross section be leg-of-mutton heating column assembly to array on the described heat sink body; Be distributed with thermal conductivity region between the described heating column assembly.

Further, above-mentioned LED street lamp radiating subassembly, wherein, the height unanimity of described heating column assembly.

Further, above-mentioned LED street lamp radiating subassembly, wherein, described heating column assembly divides two zones mutually back to distribution is set.

Adopt technical solutions of the utility model, rely on cooperating of heating column assembly and thermal conductivity region, greatly strengthened cross-ventilation effect and whole area of dissipation, the work that helps the LED street lamp is dispelled the heat, and promotes its working life, is worthy to be popularized.

The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.

Description of drawings

Fig. 1 is the organigram of LED street lamp with radiating subassembly.

The implication of each Reference numeral is as follows among the figure:

1 heat sink body, 2 heating column assemblies

The specific embodiment

LED street lamp radiating subassembly as shown in Figure 1 includes heat sink body 1, and its unusual part is: array is distributed with heating column assembly 2 on heat sink body 1.And, between heating column assembly 2, be distributed with thermal conductivity region.

From implementation process of the present utility model, in order to help effective convection current of hot and cold air, the heating column assembly 2 of employing height unanimity each other.Further, consider that can carry out a single guiding to the trend of air-flow divides, allow air-flow shuttle back and forth fast in thermal conductivity region, the cross section of the heating column assembly 2 that the utility model adopted is a triangle.

Moreover, in order can effectively to dredge the air-flow of both direction simultaneously, to promote the flow efficiency of air-flow and then improve the effect of heat radiation, 2 fens two zones of leg-of-mutton heating column assembly are mutually back to setting, promptly as shown in Figure 1.Like this, the thermal current no matter work of LED street lamp produces from which direction flows out, and all can access and dredge.

By above-mentioned character express and in conjunction with the accompanying drawings as can be seen, adopt the utility model after, rely on cooperating of heating column assembly and thermal conductivity region, cross-ventilation effect and whole area of dissipation have greatly been strengthened, help the work heat radiation of LED street lamp, promote its working life, be worthy to be popularized.

Certainly, more than only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.

Claims

1.LED the street lamp radiating subassembly includes heat sink body, it is characterized in that: to be distributed with cross section be leg-of-mutton heating column assembly to array on the described heat sink body; Be distributed with thermal conductivity region between the described heating column assembly.
