Description
Technical field
The utility model relates to the lighting design field, is specifically related to a kind of LED light fixture that is easy to dispel the heat.
Background technology
LED is light emitting diode, is the new technology that grows up mid-term in 20th century.It relies on the electronics in the heterojunction semiconductor directly luminous by the energy jump that potential barrier produces.
The light fixture of making by LED does not produce heat owing to luminescence process, and energy conversion efficiency approaches absolutely, and overlong service life is the developing direction of lighting engineering.
Generally, the LED light fixture comprises lampshade, the LED luminescence component between lamp socket and lampshade of lamp socket, lamp socket top and is located at LED luminescence component cooling mechanism all around.
During the work of LED luminescence component, will produce a large amount of heat, these caloric requirements lose by cooling mechanism, otherwise, with the life-span that greatly shortens the LED light fixture.
The application number radiator structure of a kind of LED that has been 200910037231.9 Chinese disclosure of the Invention comprise the radiator of being made by hot good conductor, and at least one is installed in the LED on the described radiator.It is to be provided with one or one or more groove at radiator, two pins of LED are electrically connected in the described groove of rear insertion by conducting connecting part, and be fixedly clamped or undertaken fasteningly by metal or nonmetal sieve silk by groove, LED pin and radiator keep the insulation isolation.
In the prior art, the heat energy of high-power LED lamp is directly delivered in aluminium alloy or the metal shell fin-shaped fin and dispels the heat, generally, the fin-shaped fin is along arranging perpendicular to the lamp socket direction, under some occasion, because the specific (special) requirements of LED lamp installation, air-flow is perpendicular to the fin-shaped fin, and then stopped by the fin-shaped fin, be unfavorable for taking away the heat that the LED luminescence component produces, shortened the service life of LED light fixture.
The utility model content
The utility model provides a kind of LED light fixture that is easy to dispel the heat, and is simple in structure, easy to use, can make things convenient for air-flow to flow along the annular fin of LED light fixture periphery, is beneficial to the heat loss of annular fin.
A kind of LED light fixture that is easy to dispel the heat comprises lamp socket, lampshade, the LED luminescence component between lamp socket and lampshade of lamp socket top and the cooling mechanism of being located at the lampshade periphery, and described cooling mechanism is the annular fin around the circumferential distribution of shell.
During the work of LED luminescence component, will produce a large amount of heats, these heats at first are passed on the fin that is positioned at the lampshade periphery, and described annular fin is beneficial to the air-flow parallel with lamp socket to be passed through, and by Air Flow, heat is taken away.
As preferably, described lampshade comprises:
The shell of tubular, an end of this shell is connected with described lamp socket, and described annular fin is around the circumferential distribution of shell;
Light-passing board covers the opening of the described shell other end;
Annular gland around described light-passing board edge distribution, is used for light-passing board is limited to described shell edge.
Described shell is approximately tubular, and an end is connected with described lamp socket by bolt or screw, and the other end is connected with described light-passing board by annular gland, and described annular fin is around the circumferential distribution of shell.
Described light-passing board is a side of LED luminescence component dorsad, also heat sink strip can be set, and increases the surface area of light-passing board, has also namely increased area of dissipation, is beneficial to heat radiation.
As preferably, the quantity of described annular fin is 2～6.
The quantity of described annular fin is very few, and then area of dissipation is limited, is unfavorable for heat radiation, if the quantity of annular fin is too much, arranges too closely, is unfavorable for passing through of air-flow, is unfavorable for equally dispelling the heat.
For the ease of passing through of air-flow, preferably, described annular fin is parallel to each other.
Should have suitable spacing between adjacent two annular fin, spacing is wide, is beneficial to passing through of air-flow, still, the quantity of annular fin is restricted, and spacing is narrow, is unfavorable for passing through of air-flow, be unfavorable for heat radiation, preferably, the spacing of adjacent two annular fin is 5～10mm.
As preferably, the thickness of described annular fin is 2～5mm.
Described annular fin should have suitable thickness, guarantees that it has certain intensity, if blocked up, at first causes cost to increase, and secondly, also can cause the heat of annular fin to be difficult for leaving.
As preferably, the width that described annular fin radially goes up at shell is 3～8mm.
The suitable width that annular fin radially goes up at shell can guarantee the intensity of annular fin and good heat dispersion.
A kind of LED light fixture that is easy to dispel the heat of the utility model, simple in structure, easy to use, can make things convenient for air-flow to flow along the annular fin of LED light fixture periphery, be beneficial to the heat loss of annular fin, prolong the service life of LED light fixture.
