Description
Technical field
The utility model relates to the lamp heat-radiating device technical field, refers in particular to a kind of LED lamp cooling structure.
Background technology
LED gets most of the attention with characteristics such as its low-power consumption, long-life and high brightness, just gradually replace incandescent and fluorescent tube and become third generation lighting system.Each main scientific and technological power includes LED illumination project in its development plan.But LED will really become the main flow working flare, and heat dissipation problem must solve.If can not efficiently radiates heat, the LED internal temperature is raise, temperature is high more, and the luminous efficiency of LED is low more, and the life-span of LED is short more, under the serious situation, can cause the LED wafer to lose efficacy at once, and well-known heat radiation has three kinds of modes, conduction, convection current and radiation.In the great power LED cooling design, industry is generally worked hard aspect conduction, but only relies on conduction to arrive the limit, and radiator temperature is difficult to reduce again.Certainly a little temperature can also fall in weight and area of dissipation again that increase radiator, but limited eventually, so heat radiation is still the huge obstacle that great power LED is used.
Therefore, based on the defective of above-mentioned existing LED light fixture heat dissipation technology, need improve existing LED light fixture heat dissipation technology.
The utility model content
The purpose of this utility model is to provide a kind of LED lamp cooling structure at the deficiencies in the prior art, and this LED lamp cooling structure good heat dissipation effect can make led light source increase service life.
For achieving the above object, the utility model is achieved through the following technical solutions:
The LED lamp cooling structure comprises radiator, and the radiator periphery has several fins, has the heat loss through radiation dope layer on the radiator.
Described radiator top is equipped with the aluminium base that is used to install light source.
Described fin is along the radially moulding of radiator.
Has the heat loss through radiation dope layer on the described fin.
Has the heat loss through radiation dope layer on the described aluminium base.
The beneficial effects of the utility model are: by adopting conduction and two kinds of radiating modes of radiation, heat loss through conduction be the basis, heat be dispersed into radiator from light source, aluminium base, dependence be heat loss through conduction, scribbling the heat loss through radiation dope layer on radiator, fin, aluminium base, is heat loss through radiation; The utility model radiating effect is remarkable, can solve a LED light fixture heat radiation difficult problem effectively; Can satisfy the heat radiation requirement of various different lightings, and it is concisely compact, easy for installation, attractive and durable to have structure, characteristics such as good reliability.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an application schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See Fig. 1,2, the utility model LED lamp cooling structure comprises: radiator 1, and radiator 1 top is equipped with the aluminium base 2 that is used to install light source 3, and radiator 1 periphery has several fins 4, has the heat loss through radiation dope layer on the radiator 1.
Described radiator 1 is roughly cylindrical, and fin 4 is along the radially moulding of radiator 1.
Have the heat loss through radiation dope layer on the described fin 4, be higher than 55 ℃ for temperature, radiating effect is more obvious.
Have the heat loss through radiation dope layer on the described aluminium base 2, strengthen radiating effect.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, and unrestricted the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
