Description

A kind of LED indoor illumination

[technical field]

The utility model relates to the LED lighting field, specifically refers to a kind of LED indoor illumination.

[background technology]

LED is energy-conservation, efficient with it, and the advantage of environmental protection progressively substitutes the traditional lighting light source.But because the led light source volume is little, the brightness height, the heat of its generation is more concentrated, therefore uses the lighting of LED as light source, effectively solves its heat dissipation problem and just becomes particularly important.Present common LED lighting, the overwhelming majority is provided with huge and heavy heat abstractor by the heat conduction heat to be distributed.This structure and heat dissipating method are nowhere near to high-power LED light source, therefore, occur that led light source is easy to be burnt out and the normal use that influences whole light fixture.

[utility model content]

The utility model purpose is to solve the above problems, and a kind of LED indoor illumination is provided, and not only its structure is light and handy, and good looking appearance is suitable for room lighting, and can effectively improve radiating efficiency, prolongs the life-span of LED, guarantees the normal use of LED illuminating lamp.

The utility model LED indoor illumination, comprise led light source and the wiring board that led light source is installed, be located at the printing opacity face shield of led light source outside and the lamp holder that is electrically connected, it is characterized in that: described wiring board is bonded on the heat abstractor, described heat abstractor is made into integration by the radiator of hollow and the chimney-like cylinder that is positioned on radiator one end face, along described radiator a plurality of radiating fins are set at interval circumferentially, described radiator, the compartment of chimney-like cylinder and radiating fin forms a plurality of direct and cross-ventilated heat dissipation channels, after described printing opacity face shield cover is buckled in described led light source, its lower limb and described radiator closely fasten and sealing, its top edge leaves an opening that cooperates with described chimney-like cylinder outer wall, and described chimney-like cylinder mouth is exposed to OFP by described opening.

Preferably, comprise that also one is built-in with the housing of power supply, this shell nozzle one end is provided with a dismountable cover plate and is connected with radiator, and the other end is connected with lamp holder relatively.

Be provided with radiator and described cover plate, the reference column of housing mechanical connection and the through hole that passes for a circuit positive and negative lead wires between the described adjacent radiating fin.

Described wiring board is a ring-type, and its center is passed the chimney-like cylinder and is bonded on radiator one end face by heat conductive silica gel.

Described led light source be arranged in described loop line plate around.

The inwall of described chimney-like cylinder is provided with fin.

The beneficial effect that the utility model brings: the wiring board that is welded with led light source is bonded on the radiator end face by the coating heat conductive silica gel, heat is transmitted on the heat abstractor, what the compartment of radiator, chimney-like cylinder and the radiating fin that is communicated with by hollow formed again a plurality ofly directly dispels the heat with cross-ventilated passage, improve radiating efficiency greatly, thereby made the purpose that is issued to effective solution heat dissipation problem in the situation that does not need to increase heat sink material and increase light fixture weight.

[specific embodiment]

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Be to be understood that concrete embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Referring to Fig. 1～Fig. 3, the LED indoor illumination of present embodiment comprises led light source 1, the wiring board 2 of led light source 1 is installed, described wiring board 2 can be each led light source independently, also can be shared one of all led light sources, present embodiment is a loop line plate.Heat abstractor is made into integration by the radiator 3 of hollow and the chimney-like hollow cylinder 4 that is positioned on radiator 3 one end faces, and its hollow space is communicated with.Circumferentially at interval a plurality of radiating fins 5 are set along described radiator 3, so can form some convection channel that directly contact at the compartment of radiator 3, chimney-like cylinder 4 and radiating fin 5 and dispel the heat with air.

One cavity housing 8 is set between radiator 3 and lamp holder 7, places Switching Power Supply in its chamber, housing 8 openings one end be provided with one can with the cover plate 9 of housing dismounting, cover plate 9 is connected with housing 8 by connecting screw 10.An end relative with openend on the housing 8 is connected with lamp holder 7 by screw thread or other mechanical systems.Be provided with reference column 11 between radiating fin 5, the reference column 11 that set screw 12 passes on housing 8, cover plate 9 and the radiator 3 couples together this three part.Through hole 14 and the via hole 15 on the cover plate 9 that the circuit positive and negative lead wires 13 of drawing on the wiring board 2 passes on the radiator 3 are connected on the Switching Power Supply of installing in the housing 8.

In addition, described led light source 1 evenly be arranged in loop line plate 2 around, the center of loop line plate 2 is passed chimney-like cylinder 4 usefulness heat conductive silica gels and is bonded on radiator 3 end faces.

For increasing area of dissipation, a series of fins 16 are set on the inwall of chimney-like cylinder 4.

Face shield 17 adopts the good material of light transmission, and can make light soft and even at some scattering diluents of its surface applied.After face shield 17 covers are buckled in the outside of led light source 1, its lower limb and radiator 3 closely fasten and sealing, its top edge leave one with the close-fitting opening 18 of outer wall of chimney-like cylinder 4, chimney-like cylinder mouth is exposed to the outside of face shield 3 by opening 18, like this, whole light fixture has just formed some and cross-ventilated heat dissipation channel at the radiator 3 of hollow, the cavity of chimney-like cylinder 4, the compartment of radiating fin 5, has improved radiating efficiency greatly.

In addition, described printing opacity face shield 17 can be made the rule body shape according to decoration and needs attractive in appearance, as cylinder, and spheroid, spheroid or other irregular body shapes.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
