Abstract
The invention discloses an LED (light emitting diode) street lamp structure with heat conducting holes and a hot runner, comprising a heat dissipation plate. The heat dissipation plate is provided with a plurality of convex cooling fins, and the side faces of the cooling fins are provided with a plurality of evenly distributed heat conducting holes. According to the LED street lamp structure with the heat conducting holes and the hot runner, the heat dissipation plate is provided with the plurality of evenly distributed cooling fins, two sides of the cooling fins are provided with the plurality of heat conducting holes, the cooling fins and the heat conducting holes are matched with holes in a dust cover above the cooling fins to form the hot runner, cool air can effectively flow from bottom to top and flow out through the dust cover; when the LED street lamp is hot, a channel effect is generated, and the heat dissipation performance of the street lamp is increased, therefore, the design is an effective heat dissipation design completely in accordance with a physical law. The design of the LED street lamp structure is simple, is easy to realize, and has good application prospects.
Description
Technical field
The invention belongs to the fitting structure technical field, be specifically related to a kind of LED lamp post structure with thermal hole hot flow path.
Background technology
Global climate warms up the great bodily injury that causes earth environment, and energy-saving and emission-reduction just become all responsibilities, because energy-conservation letter row's demand; The street lamp of road lighting begins to convert into the LED street lamp, with the conventional road lamp difference be that cold more conversion efficiency is high more for the LED street lamp, the design of present street lamp all has a sheet heat radiator; But Design of for heat sinks not exclusively rationally, has design to forward radiating fin to below to avoid bird dung dust to attach work at present, still but runs in the opposite direction toward the convective principles that rises with heat; So long-pending need of hot side significantly strengthened, and when radiating fin is located at the top, has only the side air-flow to get into; It is disadvantageous rising for heat; Can't produce the available heat disturbance, radiating effect is poor, causes LED street lamp conversion efficiency low.
Summary of the invention
The technical problem that the present invention solved is that to overcome in the prior art LED road lamp cooling structural design unreasonable, and radiating effect is poor, thereby causes the low problem of LED conversion efficiency.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopted is:
A kind of LED lamp post structure with thermal hole hot flow path comprises heat sink, it is characterized in that: said heat sink is provided with several protruding radiating fins, and the side of said radiating fin is provided with a plurality of equally distributed thermal holes.
Aforesaid LED lamp post structure with thermal hole hot flow path, it is characterized in that: the diameter of said thermal hole is between 3mm-5mm.
Aforesaid LED lamp post structure with thermal hole hot flow path is characterized in that: the thickness of said each radiating fin is between 1.0mm-1.5mm, between the height 7mm-12mm.
Aforesaid LED lamp post structure with thermal hole hot flow path is characterized in that: the thickness of said each radiating fin is 1.2mm, highly is 9mm.
The invention has the beneficial effects as follows:, heat sink is provided with several equally distributed radiating fins, and the radiating fin both sides are provided with a large amount of thermal holes; Cooperate the hole of top dust cover to form a hot flow path, let cold air effectively flow to the top, flow out through dust cover from the below; When the LDD street lamp is warm, then produce first-class channel effect, increased the heat dispersion of street lamp, meet the effective heat dissipation design of physical law fully; Simplicity of design realizes easily, has a good application prospect.
Description of drawings
A kind of LED lamp post structure sketch map of Fig. 1 with thermal hole hot flow path.
The implication of drawing reference numeral is following:
1: heat sink; 2: radiating fin; 3: thermal hole.
The specific embodiment
To combine Figure of description below, the present invention will be further described.
As shown in Figure 1, a kind of LED lamp post structure with thermal hole hot flow path comprises heat sink 1, and said heat sink 1 is provided with several equally distributed radiating fins 2 and a plurality of thermal holes 3; The empty quantity of the heat conduction of radiating fin 2 one sides here is designed to nine, and nine thermal holes 3 directly pass through to radiating fin 2 one sides from the below, and hot-air is a kind of physical effect toward rising, and flow air can high 1-5 times than static air heat transfer efficiency; Thermal hole 2 cooperates the hole of top dust cover to form a hot flow path, lets cold air effectively flow to the top from the below, flows out through dust cover; When LED street lamp adstante febre, then produce first-class channel effect, meet the effective heat dissipation design of physical law fully; And the diameter of each thermal hole 3 is between 3mm-5mm, and size to fit can play the effect of conducting air-flow; Can also prevent effectively that impurity from getting into lamp body, the thickness of each radiating fin 2 is between 1.0mm-1.5mm, between the height 7mm-12mm; Preferred thickness is 1.2mm, highly is the radiating fin 2 of 9mm, under the situation of saving material; Can better satisfy the thermal conduction effect of LED, heat dispersion and the efficient conversion performance that has increased the LED street lamp of the present invention, energy-conserving and environment-protective; Simplicity of design realizes easily, has a good application prospect.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
