Abstract
The utility model relates to the technical field of LED illumination, in particular to an LED cooling fin and an LED streetlamp. The LED cooling fin comprises a substrate and a plurality of cooling fin bodies evenly distributed on the substrate, wherein the cooling fin bodies are perpendicular to the substrate and are provided with multiple array through holes perpendicular to the cooling fin bodies, and the lower end of the substrate is provided with a clamping portion. By means of the arrangement of the cooling fin bodies, the heat dissipation area of the substrate is increased. Besides, by means of the arrangement of the array through holes, air can be exhausted or enter the cooling fin easily, heat exchange speed is increased, thermal discharge efficiency is improved, and accordingly the LED streetlamp always works in a safe temperature range.
Description
Technical field
The utility model relates to LED lighting technical field, particularly a kind of LED fin and LED street lamp.
Background technology
LED is light emitting diode, is a kind of semiconductor solid luminescence device.It is to utilize solid semiconductor chip as luminescent material, in semiconductor, by carrier, occurs compoundly to emit superfluous energy and cause photo emissions, directly sends each coloured light such as red, blue, green.LED illuminating product utilizes LED as the produced ligthing paraphernalia of light source exactly.Under the background raising once again in Present Global energy starved worry, saving the energy is the important problem that we face, at lighting field, the application of LED luminous product is just attracting common people's sight, LED is as a kind of novel green light source product, must be the development trend of lighting engineering, 21st century take the novel illumination light source epoch that LED is representative being.LED be called as the 4th generation lighting source or green light source, there is the features such as energy-saving and environmental protection, the life-span is long, volume is little, can be widely used in the fields such as various indications, demonstration, decoration, backlight, general lighting and urban landscape.
LED product has wide market prospects beyond any doubt, especially at lighting field, will be the revolution that the mankind are thrown light in history, but can't extensively promote at present by the restriction of the factors such as technology if LED light source is widely used in lighting field.First, no matter be the sealing problem what LED product is all faced with waterproof, protection against the tide, if process the bad service life that will directly affect LED product, and these safeguard procedures can cause LED lamp ambient temperature to rise; Secondly, after ambient temperature raises, LED light source internal resistance meeting reduces, if use voltage-stabilized power supply power supply can cause LED operating current to raise, after surpassing its rated operational current, can affect the service life of LED product, and the serious LED light source that will make " burns out ".So the LED lamp especially heat dissipation problem of high-powered LED lamp is the Main Bottleneck of its extensive use of restriction.
LED street lamp particularly, due to the efficient height of street lamp, therefore, the caloric value of LED street lamp is larger, if can not timely and effectively dispel the heat, is deposited in LED light source heat around and will causes light source to be decayed fast, and energy consumption increases, thereby affects life-span and the stability of LED lamp.
Utility model content
The utility model is a kind of LED fin providing and the LED street lamp with described LED fin in order to solve the undesirable problem of current LED road lamp cooling effect.
For reaching above-mentioned functions, the technical scheme that the utility model provides is:
A kind of LED fin, comprise substrate and be evenly arranged at several radiating fins on described substrate, described radiating fin is perpendicular to described substrate, offers the perpendicular array through-hole of several and described radiating fin on described radiating fin, and the lower end of described substrate is provided with holding section.
Preferably, on described holding section, offer slot.
Preferably, the thickness of described radiating fin is 0.5mm～1.5mm.
Preferably, the material of described fin is aluminium alloy or red copper.
The utility model also provides a kind of LED street lamp, and described LED street lamp comprises fin, and described fin is above-mentioned arbitrary LED fin.
The beneficial effects of the utility model are: a kind of LED fin, comprise substrate and be evenly arranged at several radiating fins on described substrate, described radiating fin is perpendicular to described substrate, on described radiating fin, offer the perpendicular array through-hole of several and described radiating fin, the lower end of described substrate is provided with holding section; By being set, improved some radiating fins the area of dissipation of substrate, in addition, and by array through-hole is set, make air easily discharge and enter fin, accelerated the speed of heat exchange, improved the efficiency of hot driving, thereby LED lamp is worked all the time in the temperature range of safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be further elaborated:
A kind of LED fin as shown in Figure 1, comprise substrate 1 and be evenly arranged at several radiating fins 2 on substrate 1, radiating fin 2 is perpendicular to substrate 1, offers the perpendicular array through-hole 21 of several and radiating fin 2 on radiating fin 2, and the lower end of substrate 1 is provided with holding section 3.Array through-hole 21 is set and is conducive to extraneous mobile normal temperature air and enters fin inside, take the air of fin internal high temperature simultaneously out of, thereby accelerated the speed of fin heat exchange, guarantee in the temperature range of fin in a safety.On holding section 3, offer slot 31, have the raised line of projection a little in slot 31, slot 31 is for being connected with lampshade.
In the present embodiment, comprehensive heat dispersion and price are considered, the preferential aluminium alloy of material of fin.Certainly fin we can follow according to product need to select other the material such as red copper, when reality is used, consider processing cost and material cost, the thickness employing 0.5mm～1.5mm of fin is good.
The LED street lamp that the utility model provides, preferably the fin of above-described embodiment is as the fin of LED street lamp.
The above embodiment, it is preferred embodiments of the present utility model, be not to limit practical range of the present utility model, the equivalence of doing according to structure, feature and principle described in the utility model claim therefore all changes or modifies, and all should be included in the utility model patent claim.
