Abstract
The utility model discloses a heat dissipation LED lamp. The heat dissipation LED lamp comprises a top cover, a cooling fin and an LED lamp, the cooling fin is mounted above the LED lamp, the top cover is mounted above the cooling fin, the top cover is circular arc-shaped, the cooling fin and the top cover are connected through needle-shaped upright posts which are distributed uniformly, and a plurality of vent holes are uniformly formed in four sides of the top cover. The heat dissipation LED lamp dissipates heat through the cooling fin; the cooling fin is uniformly distributed with needle-shaped upright posts, the needle-shaped upright posts are connected to the top cover, so that the heat dissipation effect is strengthened; a gap is formed between each two needle-shaped upright posts, so that the heat dissipation LED lamp is capable of dissipating heat better and more quickly through the natural convection of air.
Description
Technical field
The utility model relates to technical field of lamps, particularly a kind of heat radiating LED lamp.
Background technology
In the broad regions such as outdoor road surface, square, traditional lighting is high-pressure mercury lamp or metal halide lamp.The light efficiency of high-pressure mercury lamp or metal halide lamp is 60～80lm/W, and the life-span is about 6000 hours.At present, the light efficiency of LED light fixture is 100～120lm/W, and the life-span is up to more than 25000 hours, and containing harmful mercury metal.Along with the development of semiconductor technology, the performance of these aspects is also improving constantly.Therefore in recent years, the LED lighting of environmental protection and energy saving started popular on market gradually.
The problem of heat radiation is the problem that LED lighting needs the best solution of continuous demand always, not resolving heat dissipation problem will affect the service life of light fixture, LED light source is generally all arranged in the shell of street lamp, only rely on the louvre arranging on shell in time dissipation of heat to be gone out, and in the energy consumption of LED, more than approximately 80% be converted into heat at present, and semiconductor devices is non-refractory, so many LED concentrates on relatively little space, the heat that continues accumulation will make LED chip temperature too high, if produced heat can not be dissipated immediately, at high temperature can there is the degradation in light efficiency and life-span in LED.
Utility model content
The utility model technical issues that need to address are that existing LED lighting heat radiation is bad, affect service life.
For solving the problems of the technologies described above, the utility model provides a kind of heat radiating LED lamp, comprise top cover, fin and LED lamp, above described LED lamp, be provided with fin, above described fin, be provided with top cover, described top cover is circular arc, and connects by equally distributed needle-like column between described fin and top cover, is also evenly provided with multiple ventilating openings around described top cover.A kind of heat radiating LED lamp of the present utility model, dispels the heat by fin, and on fin, has been uniformly distributed needle-like column, and needle-like column is connected on top cover, strengthen three people's effect, and had space between needle-like column, can dispel the heat better faster by the free convection of air.
As optimal technical scheme of the present utility model, the cross section of described needle-like column is circle, ellipse or cross; Around described top cover, be provided with the supporting surface that a circle tilts to the inside, on described supporting surface, be evenly provided with multiple ventilating openings.The cross section of needle-like column can be set to different shapes as required, is provided with the supporting surface that a circle tilts to the inside around top cover, and on supporting surface, ventilating opening is evenly set, and can prevent the inside that rainwater etc. enters etc., affects service life.
A kind of heat radiating LED lamp of the present utility model, is transferred to the heat of fin on top cover by needle-like column, simultaneously gapped between needle-like column, can dispel the heat by the convection current of air.A kind of heat radiating LED lamp of the present utility model, simple in structure, easy to make, good heat dissipation effect, can be widely used in the conventional fields of LED lamp such as street lamp simultaneously.
