Abstract
The utility model discloses an LED lamp with an efficient radiating structure. The LED lamp comprises a lamp cap (4) and an LED light source, the LED light source is arranged inside a lampshade (3), and primary radiating fins (1) and secondary radiating fins (2) are arranged on the periphery of the lampshade. By the aid of collocation of the different primary radiating fins and the secondary radiating fins and by various mix-matches and arrays of the primary radiating fins and the secondary radiating fins in variety (shape, size and the like) and quantity, radiation of the LED lamp can be achieved efficiently, and accordingly service life of the lamp is prolonged.
Description
Technical field
The utility model relates to high-powered LED lamp, relates in particular to a kind of high-power LED lamp with high-efficiency heat radiation structure.
Background technology
Existing LED light fixture all refers to the LED light fixture under normal condition usually.And be subjected to the restriction of size, and the area of dissipation less of light fixture, the power of LED light fixture is larger, the crystallization temperature of lamp housing and LED can be higher during use, and the light decay of LED will aggravate, and namely the life-span of LED light fixture just can shorten, so, under limited size, can not make the LED light fixture of relatively high power.In order to improve heat radiation, usually along with the increase of lamp power, be exactly to amplify accordingly.But be subjected to the occasion of size restrictions at some, because the appearance and size of light fixture is larger, then can't install, so that this kind LED light fixture can't extensive use.Amplify simultaneously, so that the weight of light fixture strengthens, cost rises.It very much not is a way that well solves heat radiation that obvious light fixture size adds.When usually if the LED lamp light source is arranged on below the radiating fin, the impact that up rushed by thermal energy, top radiating fin conduction and the width of cloth penetrate a large amount of thermal energy, thus the reduction lamp temperatures.But in some cases, light fixture needs to install conversely, and the installation that perhaps has certain gradient will make the temperature of light fixture improve significantly like this, thereby reduces the service life of light fixture.
Therefore, developing the light fixture with high-efficiency heat radiation structure, is the industry problem demanding prompt solution.
Summary of the invention
The utility model is in order to solve the problems of the technologies described above, but proposes a kind of LED light fixture of long service life of high efficiency and heat radiation.
A kind of light fixture with high-efficiency heat radiation structure that the utility model proposes, it comprises lamp holder, led light source, described led light source is located at lampshade inside, this lampshade is arranged with main radiating fin and inferior radiating fin outward.
Preferably, described main radiating fin and time radiating fin are symmetric arrays or asymmetric geometry.
Preferably, described main radiating fin becomes a kind of or irregularly shaped wavy shape of cylinder, polygon cylinder or rectangular cylinder etc. with time radiating fin permutation and combination.
Preferably, the sheet number of described main radiating fin and time radiating fin is odd number or is even number.
The angle of each main radiating fin and time radiating fin can be consistent, as all being longer than on the same plane, also can be inconsistent, and such as long respectively diverse location etc.
The utility model utilizes the collocation of different main radiating fins and time radiating fin, utilizes main radiating fin and kind (shape, size etc.), the quantity of time radiating fin to do various mixing and takes and arrange, and can solve efficiently the heat dissipation problem of LED light fixture.Under limited size, by the radiating fin of different directions, heat is farthest conducted and radiate, reduce lamp surface and LED crystallization temperature, thereby improve the life-span of light fixture.
Description of drawings
Below in conjunction with embodiment and accompanying drawing, the utility model is elaborated, wherein:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the structural representation of the utility model preferred embodiment, described light fixture with high-efficiency heat radiation structure comprises lamp holder 4, lampshade 3.Led light source is located at the inside of lampshade.These lampshade 3 outer main radiating fin 1 and time radiating fins 2 of being arranged with.Each main radiating fin and time radiating fin can be symmetric arrays or asymmetric geometry.Each main radiating fin and time radiating fin can be combined into into cylinder or polygon cylinder, rectangular cylinder.Each main radiating fin and time radiating fin can also form irregular shape or wavy shape etc.
The sheet number of main radiating fin and time radiating fin can be odd number, also can be even number.The angle of each main radiating fin and time radiating fin can be consistent, as all being longer than on the same plane, also can be inconsistent, and such as long respectively diverse location etc.The utility model does not limit number and the arrangement mode of main radiating fin and time radiating fin and generates plane and angle, only needs to reach the needed heat radiation of lighting and gets final product.
The utility model conducts and radiation mutually by main radiating fin and time radiating fin, and the heat that light source is sent in time conducts, radiate to extraneous (such as air), thereby reduces the crystallization temperature of light fixture and LED.When needs increase the light source of inside of light fixture, only need suitably to increase main radiating fin and time radiating fin gets final product.When light fixture needs any angle or any direction to put, because this radiator structure all can good heat conductive be gone out, namely can not increase lamp outer casing temperature and LED crystallization temperature, namely also can not affect the life-span of LED.
The utility model utilizes the collocation of different main radiating fins and time radiating fin, utilizing main radiating fin and kind (shape, size etc.), the quantity of time radiating fin to do various mixing takes and arranges, can solve efficiently the heat dissipation problem of LED light fixture, thereby improve the life-span of light fixture.
