Description
Technical field
The present invention relates to a kind of lighting source, particularly a kind of compact LED lamp.
Background technology
Compact LED lamp has characteristics such as efficient, environmental protection and volume are little, and the substitute that makes it to become incandescent lamp and electricity-saving lamp has become the target of the eager pursuit of people.But there is following problem in existing compact LED lamp: the one, and relatively poor its luminous efficiency and the stability of influencing of its heat dispersion, the 2nd, the relatively poor comfort level that influences its illumination of the uniformity of illumination, the 3rd, its structure is its production efficiency of complex effects and cost comparatively.So these technical problems of necessary solution.
Summary of the invention
The objective of the invention is to provide a kind of good heat dispersion performance, simple in structure and illumination uniformity compact LED lamp preferably.
In order to achieve the above object, the present invention adopts following technical scheme: according to the present invention, compact LED lamp is characterized in that it comprises: a lamp housing; A metal support that is constituted by metal buckets and metal terrace with edge; Go to the bottom and the bucket end of said metal buckets of said metal terrace with edge, fixed; Make said metal buckets and said metal terrace with edge constitute incorporate metal support, and each side of the metal terrace with edge of said metal support is provided with at least one LED assembly; An insulating part, the bung end of the metal buckets of its upper end and said metal support is fixed; A lamp holder, the lower end of it and said insulating part is fixed; A control circuit device; It is arranged on the inside of the metal buckets of said metal support; Its two inputs are electrically connected with two electrodes of said lamp holder, and its two outputs are electrically connected with two inputs of the load that is made up of said LED assembly.
In order to increase the luminous flux that compact LED lamp produces, on the upper bottom surface of the metal terrace with edge of said metal support, also the LED assembly can be set;
For the quality that alleviates compact LED lamp and reduce its cost; The metal terrace with edge of said metal support can be its inner and its middle part of going to the bottom all by the metal terrace with edge of hollow out, the bucket of the metal buckets of said metal support can be provided with at the end one with the identical through hole of said metal terrace with edge bottom surface shape.
Described lamp housing can be a bubble shape lamp housing, also can be the lamp housing of other shape.Described lamp housing can be a glass lamp housing, also can be the plastics lamp housing, can also be the lamp housing that other light transmissive material is processed.Certain color can be coated in inside at said lamp housing, as make it to become the lamp housing of coating white in the inner coated white of glass lamp housing.Described lamp housing can also carry out frosted to be handled to change its reflection of light characteristic, handles as on glass lamp housing, carrying out frosted.
In order to increase its radiating effect, on the outer surface of the metal buckets of said metal support, heat radiation rib (or being called fin) can be set.Its heat radiation rib can be the bar shaped heat radiation rib that the metal buckets along said metal support distributes up and down, also can be the annular heat radiation rib that the metal buckets around said metal support distributes.
The metal terrace with edge of described said metal support can be metal three terrace with edges, can be the metal truncated rectangular pyramids, also can be metal five terrace with edges, can also be other metal terrace with edge.
For the ease of ventilation and heat, in the bucket bottom of the metal buckets of said metal support air vent can be set, also air vent can be set in the bottom of said insulating part.
The employed material of said metal support is aluminum or aluminum alloy materials normally, also can be other metal material.
Described lamp holder can adopt screw socket type lamp holder, also can adopt the bayonet type lamp holder, can also adopt the lamp holder of other type.
The present invention has following good effect:
At first; Compact LED lamp of the present invention; Because the LED assembly is arranged on the side of metal terrace with edge of said metal support or on the upper bottom surface; The heat that its LED assembly is produced can pass to said metal support effectively, because the surface area of the metal buckets of its metal support is big and direct and surrounding air is carried out the convective exchange heat, so apparatus of the present invention have good heat-radiation effect; Secondly; The LED assembly of apparatus of the present invention is arranged on each side of metal terrace with edge of said metal support or on the upper bottom surface; Because the side of its metal terrace with edge has between certain space angle and each side with respect to upper bottom surface certain space angle is also arranged; So just make that the spatial distribution of luminous intensity of each LED assembly is different, make that its illumination uniformity of area of illumination is significantly improved in the space; At last,, make it simple in structure, have production efficiency height, characteristics that production cost is low because apparatus of the present invention have adopted the incorporate metal support that is made up of said metal buckets and said metal terrace with edge.
Description of drawings
Fig. 1 is the sketch map of compact LED lamp of the present invention;
Fig. 2 has showed second embodiment of compact LED lamp of the present invention.
The specific embodiment
Fig. 1 is the sketch map of compact LED lamp of the present invention.Visible from figure, apparatus of the present invention comprise: lamp housing 6; By the incorporate metal support that metal buckets 3 and metal terrace with edge 1 are constituted, going to the bottom of metal terrace with edge 1 is fixing with the bucket end 2 of metal buckets 3, and metal terrace with edge 1 is a metal truncated rectangular pyramids, on four sides of metal truncated rectangular pyramids, all is provided with a LED assembly 5; Insulating part 4, the bung end of the metal buckets of its upper end and said metal support is fixed; Lamp holder 8, the lower end of it and insulating part 4 is fixed; Control circuit device 7; It is arranged on the inside of the metal buckets of said metal support; Its two inputs are electrically connected (not drawing among the figure) with two electrodes of said lamp holder, and its two outputs are electrically connected (not drawing among the figure) with two inputs of the load that is made up of said LED assembly.
In the present embodiment: metal support adopts aluminum to use the integrated manufacturing of mould to form; Lamp housing 6 is a bubble opaque lamp housing, and lamp holder 8 is a screw socket type lamp holder.
When lamp holder 8 energisings; Control circuit device 7 provides operating current for described LED assembly 5; The heat that is produced during each LED lamp assembly work mainly passes on the metal truncated rectangular pyramids of metal support; Be delivered to again on the metal buckets of metal support, carry out heat exchange with ambient air then and be delivered to around environment in go, this kind structure has higher heat dispersion.Find out easily also that from figure this kind compact LED lamp is arranged on four LED assemblies on four sides of metal truncated rectangular pyramids, formed illumination range is big, and can form irradiation more uniformly at the area of space that shone.
