Description
Technical field
The utility model belongs to the LED lighting, is meant that especially a kind of lampshade has two ventilating openings to utilize the light fixture structure-improved of cross-ventilation reinforced platoon thermal effect.
Background technology
LED becomes the light source of following illumination already, and uses LED also to become the trend of lighting as light source.Yet; In the electric energy because of the feasible input of thermal resistance LED in the LED luminescence process, the 15% effective compound light that is converted into of only having an appointment, most of (about 85%) is because of the invalid compound heat that is converted into; Produce a large amount of heat energy; Make the temperature of LED raise, and high temperature cause the deterioration even the damage of the performance of LED, makes the luminous efficiency of LED and service life reduce.
Therefore heat dissipation design is the design focal point of LED light fixture always.As use metal material as lamp socket and increase copper high thermal conductivity coefficient material and be beneficial to heat conduction, fin be set on lamp socket to increase area of dissipation, so that the heat energy that LED was produced is conducted dissipation rapidly.But except the heat exchange pattern via the contact of LED lamp plate, the air in the lampshade also contacts LED generation high temperature and is heated.Mostly the lampshade of existing LED bulb be hemispherical and connect airtight with lamp socket and form airtight space, and so that even bright dipping to be provided, but this structure makes too high its luminous efficiency that influences of temperature of lampshade inner air.
In view of this, the utility model provides a kind of light fixture structure-improved, utilizes the principle of thermal convection current to make the air in the lampshade be able to circulation, avoids influencing because lampshade structure changes the usefulness of light fixture simultaneously.
Summary of the invention
The main purpose of the utility model aims to provide the light fixture structure-improved that a kind of lampshade inner air can circulate.
For reaching above-mentioned purpose, the light fixture structure-improved of the utility model, a pedestal with hollow; This pedestal upper end has a lamp source decorating plate; And the upper limb of this pedestal is provided with a junction surface and a wind slot part, this junction surface and this lamp source decorating plate tubulose that is formed by connecting, and the internal diameter of this wind slot part is slightly larger than the internal diameter at this junction surface and is connected with this junction surface; This light fixture structure-improved has more a cross-ventilation formula lampshade and is sheathed on this pedestal and engages with this junction surface; This light fixture is structure improved to be characterised in that: this cross-ventilation formula lampshade presents the gill fungus shape, has a ventilation slot, and this ventilation slot and this wind slot part form one first ventilating opening of circulation of air; This cross-ventilation formula lampshade is provided with one second ventilating opening in addition, and this second ventilating opening is positioned at gill fungus pleat place and relative with this first ventilating opening.Wherein, this convection type lampshade is a light-transmitting materials.Wherein, this pedestal is the material of high thermal conductivity coefficient.Wherein, the external diameter of this ventilation slot is less than the internal diameter of this wind slot part.
Group is established for ease, and cross-ventilation formula lampshade has at least one assembled portion.And the external diameter of this assembled portion equals or is slightly larger than the internal diameter at this junction surface.
By said structure, the utility model provides a kind of light fixture structure-improved, and the channel of ventilation is offered in the appropriate location on lampshade, utilizes thermal convection principle to make the air in the lampshade be able to circulation, avoids influencing because lampshade structure changes the usefulness of light fixture bright dipping simultaneously.

The specific embodiment
For making your juror can know the content of understanding the utility model, sincerely graphic with the description collocation, please consult.
See also Fig. 1～Fig. 3, be constitutional diagram, exploded view and the profile of the utility model preferred embodiment.Shown in figure, the utility model light fixture structure-improved has a pedestal 1 of hollow, and is made by the material of high thermal conductivity coefficient, like aluminum metal.This pedestal 1 upper end has a lamp source decorating plate 10, and this lamp source decorating plate 10 and this pedestal 1 integrally formed processing are installed in so that a plurality of led light sources 5 and a plurality of driving power to be provided.The upper limb of this pedestal 1 is provided with a junction surface 12 and a wind slot part 14; This junction surface 12 and this lamp source decorating plate 10 tubulose that is formed by connecting; For sheathedly engaging with a cross-ventilation formula lampshade is mutual; This convection type lampshade is a light-transmitting materials, for these led light source 5 bright dippings of adjustment, makes this light fixture structure-improved that uniform light source is provided.This cross-ventilation formula lampshade 2 has at least one assembled portion 20, and the external diameter of this assembled portion 20 equals or be slightly larger than the internal diameter at this junction surface 12, for these junction surface 12 fits after closely affixed, this cross-ventilation formula lampshade 2 is bonded with each other with this pedestal 1.And the internal diameter of this wind slot part 14 is slightly larger than the internal diameter at this junction surface 12 and be connected with this junction surface 12, for circulation of air.This light fixture is structure improved to be characterised in that: this cross-ventilation formula lampshade 2 presents the gill fungus shape; And the edge of this cross-ventilation formula lampshade 2 has a ventilation slot 22; And the external diameter of this ventilation slot 22 is slightly less than the internal diameter of this wind slot part 14, makes this cross-ventilation formula lampshade 2 relative and form one first ventilating opening 4 of circulation of air in when assembling and this wind slot part 14.This cross-ventilation formula lampshade 2 is provided with one second ventilating opening 24 in addition, is positioned at gill fungus pleat place and relative with this first ventilating opening 4.This light fixture structure-improved is under user mode; Because air receives the heat energy of these led light sources 5 and the generation of these driving powers and heats; Air is just discharged outside this cross-ventilation formula lampshade 2 from this first ventilating opening 4; And cold air just gets into this cross-ventilation formula lampshade 2 from this second ventilating opening 24, makes the inner air themperature of lampshade descend, and reaches the effect of auxiliary heat dissipation.In addition; Because LED has the directive property characteristic; The illumination light white silk that bulb provides focuses mostly in the place ahead; The change influence of lampshade both sides profile is very little, so this cross-ventilation formula lampshade 2 of gill fungus shape design also has identical even light effect with the closed lampshade, makes these led light sources 5 of spot light be converted into uniform bright dipping.
The design that the ventilation channel is offered in the utility model appropriate location on lampshade; The not only ingenious air that utilizes is changed and thermal convection principle by heat density; Make the air in the lampshade be able to circulation, hot-air is discharged and cold air flows into naturally, reduction lampshade internal temperature.Simultaneously, the design of gill fungus shape lampshade can be avoided influencing the light fixture bright dipping because lampshade structure changes, and keeps and promote the usefulness of light fixture.
The above is merely the preferred embodiment of the utility model, is not the scope of implementing in order to qualification the utility model, and other transition regimes are also all among the category of this case; So done equivalence or change easily Deng being familiar with this technology, the equalization of under the spirit that does not break away from the utility model and scope, being done changes and modification, all should be covered by in the claim of the utility model.
