Summary of the invention
The purpose of this utility model is a kind of compact conformation will be provided, have the LED illuminating lamp than high heat dispersion.Another purpose of the present utility model is the LED illuminating lamp that will provide a kind of illumination range big.Another purpose of the present utility model is the LED illuminating lamp that a kind of energy replace incandescent will be provided.
In order to achieve the above object, the utility model adopts following technical scheme: according to the utility model, a kind of LED illuminating lamp is characterized in that it comprises: a lamp housing; A round metal tube, the afterbody of its upper end and described lamp housing is fixed, and its bottom and an insulating part are fixed, and the internal fixation in the top has a metal connecting piece; A prism-shaped metal mandril, it is positioned at the inside of described lamp housing, its lower end and described metal connecting piece are fixed, and it end face and each side on all be provided with at least one led light source; A lamp holder, it is fixed in the lower end of described insulating part; A control circuit device, it is arranged on the inside of described round metal tube, and two input is electrically connected with two electrodes of described lamp holder, and two output is electrically connected with two inputs by the load that described led light source constituted.
Described led light source is meant single led or the LED module.
For the weight that reduces the LED illuminating lamp and reduce its cost, can be provided with along the cavity of axis of a cylinder direction at the middle part of described prism-shaped metal mandril, and through hole is set at the middle part of described metal connecting piece.
Described metal connecting piece can be the circular metal connector, also can be the metal connecting piece of other 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 made.Certain color can be coated in inside at described 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 can carry out frosted on glass lamp housing.
In order to increase its radiating effect, fin (or being called the heat radiation rib) can be set on the outer surface of described round metal tube.Its fin can be the bar shaped fin that distributes up and down along round metal tube, also can be the annular fin that distributes around round metal tube.
For the ease of ventilation and heat, on described round metal tube, air vent can be set; On described insulating part, also air vent can be set.
Described prism-shaped metal mandril can be a triangular column metal mandril, can be quadrangular shape metal mandril, also can be pentagonal prism shape metal mandril, can also be other prism-shaped metal mandril.
Described prism-shaped metal mandril, metal connecting piece and round metal tube adopt the integrated manufacturing of mould usually, thereby form incorporate structure, have so promptly improved its production efficiency, have improved the radiating effect of its LED illuminating lamp again.About the employed material of prism-shaped metal mandril, metal connecting piece and round metal tube normally aluminum or aluminum alloy materials, also can be other metal material.
For the heat that described led light source is produced can effectively pass to described prism-shaped metal mandril, it is fixing that the bottom of described led light source makes itself and certain plane of described prism-shaped metal mandril directly contact usually, or make its contact fixing by the heat conduction binding agent.
On described prism-shaped metal mandril, the pcb board that fixedly has single or multiple mounting hole site can be set, the mounting hole site that is positioned on this pcb board of can passing described led light source is fixed on the described prism-shaped metal mandril, and each led light source can be electrically connected by the figure metal wire of pcb board; The figure metal wire also can be set on the described prism-shaped metal mandril and between figure metal wire and described prism-shaped metal mandril insulating barrier be set, each set led light source can be electrically connected by its figure metal wire.
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 utlity model has following good effect:
LED illuminating lamp of the present utility model, because its led light source is arranged on the end face and each side of prism-shaped metal mandril, can pass to the heat that led light source produced effectively described prism-shaped metal mandril, and prism-shaped metal mandril, metal connecting piece and round metal tube three closely are fixed together, therefore, its heat also can pass to described round metal tube effectively, because its round metal tube surface area is big and direct and surrounding air convective exchange heat, so the utlity model has good heat-radiation effect; In addition, can belong on the end face of stem stem and each side because its led light source is arranged on prism-shaped, its light that sends obviously relatively disperses, its illumination range is bigger; At last, compact conformation of the present utility model has production efficiency height, characteristics that production cost is low, also has the shape attractive in appearance of similar incandescent lamp simultaneously.
Description of drawings
Fig. 1 is the schematic diagram of LED illuminating lamp of the present utility model;
Fig. 2 has showed second embodiment of LED illuminating lamp of the present utility model.
The specific embodiment
Fig. 1 is the schematic diagram of LED illuminating lamp of the present utility model.As seen from the figure, the utility model comprises: lamp housing 6; Round metal tube 3, the afterbody of its upper end and lamp housing 6 is fixed, and its bottom and insulating part 4 are fixing, and the internal fixation in the top has metal connecting piece 2; Quadrangular shape metal mandril 1, it is positioned at the inside of lamp housing 6, and its lower end and metal connecting piece 2 are fixing, are provided with a led light source 5 on its end face, respectively are provided with a led light source 5 on its four sides; Screw socket type lamp holder 8, it is fixed in the lower end of insulating part 4; Control circuit device 7, it is arranged on the inside of round metal tube 3, two input is electrically connected (not drawing among the figure) with two electrodes of screw socket type lamp holder 8, and two output is electrically connected (not drawing among the figure) with two inputs by five loads that led light source constituted.
