Description
Technical field
The utility model relates to LED street lamp technical field, specifically a kind of heat dissipation LED road lamp.
Background technology
LED and light emitting diode are a kind of semiconducting solid luminescent devices.It utilizes solid semiconductor chip as luminescent material, releases superfluous energy in the semiconductors and cause photo emissions, directly send each coloured light such as red, blue, green by carrier generation compound.LED illumination product utilizes LED as the produced ligthing paraphernalia of light source exactly.Under the background that Present Global energy starved worry raises once again, economize energy is the important problem that we face, at lighting field, the application of LED luminous product is just attract the sight of common people, LED is as a kind of novel green light source product, the necessarily development trend of lighting engineering, 21st century take LED as novel illumination light source epoch of representative by being.LED is called as forth generation lighting source or green light source, has 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 instruction, display, decoration, backlight, general lighting and urban landscape.
LED product has wide market prospects beyond any doubt, especially at lighting field, if it will be the revolution that the mankind are thrown light in history that LED light source is widely used in lighting field, but can't extensively promote at present by the restriction of the factors such as technology.First, no matter be that what LED product is all faced with waterproof, moistureproof sealing problem, if process the bad service life that directly will affect LED product, and these safeguard procedures can cause LED ambient temperature to rise; Secondly, after ambient temperature raises, LED light source internal resistance can reduce, and LED operating current can be caused to raise if use voltage-stabilized power supply to power, after exceeding its rated operational current, can affect the service life of LED product, the serious LED light source that will make " burns out ".So the heat dissipation problem of LED especially high-powered LED lamp is the Main Bottleneck of its extensive use of restriction.
Particularly LED street lamp, 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, the heat be deposited in around LED light source will cause light source rapid decay, and energy consumption increases, thus affects life-span and the stability of LED.
Utility model content
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art, solves the technological deficiency existed at present, the utility model discloses a kind of heat dissipation LED road lamp.
The technical scheme that the utility model adopts is:
A kind of heat dissipation LED road lamp, comprise diffuser, LED light emitting source, pcb board, fin and cold drawing, described diffuser and fin are tightly connected, described LED light emitting source is installed on pcb board, described pcb board is pasted with fin and is connected, described fin groove is between any two provided with cold drawing, and described cold drawing is provided with cooling line, is filled with cooling fluid in described cooling line.
Further, described cold drawing and fin removably connect, and facilitate the maintenance to cold drawing, make cold drawing keep good heat dispersion.
The beneficial effects of the utility model are,
A kind of heat dissipation LED road lamp disclosed in the utility model, fin inherently can play good radiating effect, cold drawing is provided with at the groove of fin, cold drawing is provided with cooling line, cooling fluid is filled with in cooling line, thus more accelerate the heat radiation of fin, improve the heat dissipation of LED street lamp, ensure that service life and the stability of LED street lamp.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1, diffuser 2, LED light emitting source 3, pcb board 4, fin 5, cold drawing 6, cooling line.
Detailed description of the invention
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of heat dissipation LED road lamp, comprise diffuser 1, LED light emitting source 2, pcb board 3, fin 4 and cold drawing 5, diffuser 1 and fin 4 are tightly connected, LED light emitting source 2 is installed on pcb board 3, and pcb board 3 is pasted with fin 4 and is connected, and fin 4 groove is between any two provided with cold drawing 5, cold drawing 5 is provided with cooling line 6, is filled with cooling fluid in cooling line 6.
Further, cold drawing 5 and fin 4 removably connect.
A kind of heat dissipation LED road lamp disclosed in the utility model, fin inherently can play good radiating effect, cold drawing is provided with at the groove of fin, cold drawing is provided with cooling line, cooling fluid is filled with in cooling line, thus more accelerate the heat radiation of fin, improve the heat dissipation of LED street lamp, ensure that service life and the stability of LED street lamp.
Be noted that, the above embodiment is unrestricted to the explanation of technical solutions of the utility model, the equivalent replacement of art those of ordinary skill or other amendments made according to prior art, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the interest field required by the utility model.
