Abstract
The utility model discloses a ventilating and heat radiating LED lamp which comprises a lamp housing and an LED lamp body in the lamp housing. Air outlets are arranged on the upper side portion of the lamp housing in a left and right symmetrical way, and air inlets are arranged on the lower side portion of the lamp housing in a left and right symmetrical way. The center of the heat-generating body of the LED lamp body is arranged in the lamp housing and between the air inlets and the air outlets. The LED lamp is reasonable in design, and greatly improves heat radiation efficiency by placing the center of the heat-generating body in a position where best heat radiation effect is achieved. The LED lamp can be used in combination with other heat radiation structure. The performance of a large power LED lamp is guaranteed, and the service lifetime of the LED lamp is prolonged.
Description
Technical field
The utility model relates to a kind of LED lamp, particularly a kind of circulation radiating type LED lamp.
Background technology
The LED heat dissipation problem is the bottleneck of present semiconductor technology evolves.In the prior art, the photoelectric transformation efficiency of incandescent lamp only has 3%, and the photoelectric transformation efficiency of fluorescent lamp is about 15%, and the photoelectric transformation efficiency of LED is 10% ~ 40%, has 60% ~ 90% conversion to turn to heat.Junction temperature has significant impact to the LED life-span, when junction temperature when 60 ~ 80 spend, the LED thermal conversion efficiency is about 70% ~ 80%, 10 ℃ of the every risings of temperature of general electronic component, the life-span just becomes approximately half, 2 ℃ of the every risings of temperature, reliability will descend 10%.So the heat dissipation problem of LED is to improving its electricity conversion, improving its service life and reliability is significant.
Along with the continuous increase of LED lamp capacity, to the more and more higher requirement of heat dissipation proposition of LED lamp.In the prior art, LED lamp radiator mostly is gilled radiator, after heat conducts to gilled radiator, again by the fin heat loss through radiation.Although it is simple in structure that this radiator structure has, its LED lamp that is only applicable to low capacity, for the LED lamp of high power capacity, radiating efficiency is then too low.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and the circulation that a kind of structural design is more reasonable, result of ventilating heat dissipation is good radiating type LED lamp is provided.
Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is a kind of circulation radiating type LED lamp, comprise lamp housing and be located at the interior LED lamp body of lamp housing, be characterized in: the upper lateral part at lamp housing is provided with symmetrical air outlet, the following side is provided with symmetrical air inlet, and the heater center of LED lamp body is in the lamp housing between air inlet and the air outlet.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described circulation radiating type LED lamp is characterized in: the bore of described air inlet is greater than the bore of air outlet.
Structural design of the present utility model can be combined with gilled radiator, cooling fan or other radiator structure, can further improve its radiating effect.
Compared with prior art, the utility model reasonable in design, it is in the heater center by design and places best heat radiation position, it is high greatly to have improved radiating efficiency, can use in conjunction with other radiator structure, effectively guarantee the performance of high-powered LED lamp, prolong the service life of LED lamp.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not consist of its Copyright law.
