Compared with the prior art, the external heat radiation structure radiates heat through the fin-shaped radiation fins arranged on the lamp body; the heat generated by the LED light source is radiated to the outside, so that an optimum working temperature for an LED of the LED lamp is achieved; the external heat radiation structure can be widely applied to an industrial miner lamp, a bulb lamp, a spot lamp, a lamp cup and other LED lamps; the external heat radiation structure is simple and very practical; and the purpose of the external heat radiation structure is achieved.
Description
Technical field
The utility model relates to a kind of radiator structure, particularly a kind of heat radiation structure outside that is applicable to the LED lamp.
Background technology
The abbreviation of so-called LED(Light-emitting Diode) lamp refers to adopt the semiconductor light-emitting-diode technology as a kind of novel environment friendly illuminating product of light emitting source.The LED light fixture has the characteristics such as power and energy saving, easy to control, non-maintaining, safety and environmental protection and long service life, can reach 50000-100000 hour its service life, far surpasses 1000 hours and 10000 hours of fluorescent lamp of traditional osram lamp.LED must be the trend of future development as a kind of novel energy-saving and environmental protection green light source product.
One of advantage of LED is to have very high photoelectric transformation efficiency, compare with conventional light source and to have greatly improved, but LED light fixture product still has some deficits at present, luminous efficiency is on the low side, the photoelectric transformation efficiency of main product probably still only has 15-20%, this means that nearly the electric energy of 80-85% has still converted heat to, can produce more heat when therefore working, need to use some heat dissipation equipments that heat is derived and is dispersed in the environment, otherwise will affect the service life of LED equipment even cause and to work.Owing to be subjected to the restriction of up till now technical development, heat dissipation problem is the significant challenge that the LED illumination faces always.
The main challenge that the LED heat radiation faces still is embodied in high-power lamp (such as bulkhead lamp capable, bulb lamp, shot-light and Lamp cup etc.), and the use of these great power LED equipment of stadium and court high brightness lamp heat radiation process.Because these LED plant capacities are large, required loose heat is also large.
At present the radiating mode of common LED street lamp mainly contains: Natural Heat Convection, install fan forced heat radiation, heat pipe and loop heat pipe heat radiation etc. additional.These several radiating modes have meaning and the effect of its existence, but its shortcoming and defect part is also arranged accordingly, fan cooling mode system slightly complicated for example, and low of reliability ratio often is that the life-span of fan is also shorter than chip, basically abandoned by industry now; Though and heat pipe heat radiation is accepted by industry, still comparatively forced on the extensive effect of usage comparison, often can not reach the optimum temperature that LED works.
Therefore, need especially a kind of heat radiation structure outside of LED lamp, to solve the above-mentioned existing problem that exists.
The utility model content
The purpose of this utility model is to provide a kind of heat radiation structure outside of LED lamp, for the deficiencies in the prior art, effectively plays thermolysis, makes the LED lamp reach the optimum temperature of LED work.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of heat radiation structure outside of LED lamp, it is characterized in that it comprises lamp body and the led light source that is connected with lamp body, evenly is provided with some fin-shaped fin in the outside of described lamp body, be provided with the gap between the described fin-shaped fin, the width in described gap is greater than the thickness of described fin-shaped fin.
In an embodiment of the present utility model, the setting party of described fin-shaped fin is to paralleling with the direction of illumination of described led light source.
In an embodiment of the present utility model, the setting party of described fin-shaped fin is to perpendicular with the direction of illumination of described led light source.
In an embodiment of the present utility model, the thickness of described fin-shaped fin is 0.13-0.14cm.
In an embodiment of the present utility model, the width in described gap is 0.15-0.25cm.
The heat radiation structure outside of LED lamp of the present utility model, compared with prior art, dispel the heat by the fin-shaped fin that is arranged on the lamp body, the dissipation of heat that led light source produces is gone out, make the LED lamp reach the optimum temperature of LED work, can be widely used in the LED light fixtures such as bulkhead lamp capable, bulb lamp, shot-light and Lamp cup, simple in structure, very use, realize the purpose of this utility model.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.
