Description
Technical field
The present invention relates to the luminous type of respiration cooling LED bulb of a kind of wide-angle.
Background technology
The LED bulb using in the market mainly includes lampshade, light source assembly, radiator, bulb socket, and some LED lamp has also used vent window, available technology adopting to above-mentioned parts all there is more defect, below in these specific descriptions.
The lampshade entirety using on LED lamp is at present sealed, and has just opened an opening in end for bulb socket is installed.This enclosed lampshade radiating mode is mainly that radiator outer surface and extraneous air carry out heat exchange heat radiation, air cannot enter in bulb, thereby make the integral heat sink poor-performing of bulb, have a strong impact on like this service life of bulb, in addition, lampshade and bulb socket are mostly to adopt together with chemicals fixed bonding at present, so neither also cost of idleness comparatively of environmental protection.
In use overheated in order to prevent LED lamp source, all adopt at present and a radiator is installed below illuminator is dispelled the heat.For the heat dispersion of radiator is further provided, be mainly at present to adopt to increase the volume of radiator and the contact area of air, realize as increased the modes such as fin.Radiator inside is in order to install driving power, for safety, it supports fin and mostly adopts closed design, cause the contact area opposite edges of its inner space and air and the contact area of extraneous air much smaller, add heat radiation synergistic effect, the temperature of radiator internal core will be far above the temperature at edge, adopt the mode of above-mentioned increase and air contact area to dispel the heat, because air is almost static contacting with radiator, making radiator inside is to contact with the high temperature air of periphery all the time, and it is not fine causing its integral heat sink effect.
LED lamp vent window is mainly mounted in illuminator below at present, and in radiator outside, the ventilating opening on it is mainly rectangle and is array way layout.Adopt the vent window that array way is arranged can not enter in bulb with bulk cannot make air enter time, thus cannot wind gathering, make the radiating effect of radiator limited.Due to the mostly not contact with it in radiator outside of vent window, add the enclosed design of radiator, it is not very smooth and easy making the Air Flow in vent window, is not fine thereby make the radiating effect of bulb.
Summary of the invention
Object one of the present invention: be to provide the luminous type of respiration cooling LED bulb of a kind of wide-angle, solve the large light emitting anger, the working stability performance that how to improve bulb, the problem that life-span is long, can well dispel the heat while spending and carry out the technical problem of work thereby make bulb accomplish to be greater than 300 at lighting angle.
Object two of the present invention: be to provide the luminous type of respiration cooling LED bulb of a kind of wide-angle, air can be dispelled the heat in the mode flowing in radiator inside, thereby take away the heat of radiator inside, solve the technical problem of the heat dispersion that how to improve LED lamp entirety.

Described outer panel bottom is provided with bottom buckle, and this buckle lateral surface is provided with draw-in groove.
The invention has the beneficial effects as follows:
1, because lampshade light-emitting area is that radially spaced one-tenth is gathered shape and is arranged in lamp holder periphery below, in the middle of adjacent lampshade light-emitting area, be provided with the ventilative chamber that vent window is installed, extraneous air just can enter into the radiator in lampshade through lampshade like this, contact with the inner surface of radiator, form cold-hot air convection, thereby improve significantly the integral heat sink performance of bulb, extend the service life of bulb.
2, buckle is installed in the bottom of lampshade light-emitting area, thereby the annular protrusion on groove and bulb socket on this buckle matches lampshade and bulb socket is fixed together, and has replaced the use of bonding agent, when environmental protection, can reduce the cost.
3, because upper cover heating column and lower cover heating column that electroluminescent lamp is installed are to be intervally installed, the space that centre stays can be used for the vent window that installation can be ventilative, air just can flow to radiator inside radiator integral is carried out to abundant omnibearing heat exchange like this, heat after exchange flows out from the vent window of the relative direction of radiator, thereby heat is constantly flowed out from radiator is inner, make hot-air can not stop all the time in radiator inside, in addition, adopt this design, radiator inside is cavity structure, avoid hot synergistic effect, thereby make radiator reach quick heat radiating effect.
4, owing to thermal column being installed between upper cover and lower cover, make like this air do curve in radiator cavity and rotatablely move, the time of contact of prolongation and thermal column, radiator is carried out to sufficient heat exchange.
5,, owing to processing breach on thermal column, utilize like this aerology motion principle to make cold air and hot radiator carry out sufficient heat exchange.
6, owing to being also added with several thermal columns, the radiating effect of so further raising radiator in thermal column.
7, due to upper cover and under the heating column that covers be flute profile, the convenient lamp bar assembly of installing in bottom, the convenient vent window of installing of dual-side.
8, owing to being provided with fixing buckle in mounting seat bottom, replace original and screw thread bulb socket and bonding connection, simple, convenient, environmental protection, in addition, add after 2 stopper slots, and mounting seat and bulb socket are firmly installed together.
9,, owing to being processed with air-vent below mounting seat, air just can enter from these holes and flow out like this, further improves the radiating effect of radiator.
10, because the ventilating opening in ventilating opening group becomes horn-like, it is the same that this shape is equivalent to nozzle, making air outside bulb can form one enters in bulb, in addition, 4 ventilating openings become respectively upper and lower, left and right to arrange, thereby make a large amount of air enter in bulb and carry out heat exchange with radiator.
11, owing to being provided with and being the tight locking button being symmetrical set in interior plate middle part, this tight locking button inner surface camber, thus can make vent window firmly be fixed on radiator.
12, because upper cover heating column and lower cover heating column that electroluminescent lamp is installed are to be intervally installed, the space that centre stays can be used for the vent window that installation can be ventilative, air just can flow to radiator inside radiator integral is carried out to abundant omnibearing heat exchange like this, heat after exchange flows out from the vent window of the relative direction of radiator, thereby heat is constantly flowed out from radiator is inner, make hot-air can not stop all the time in radiator inside, in addition, adopt this design, radiator inside is cavity structure, avoid hot synergistic effect, thereby make radiator reach good radiating effect.
13, owing to thermal column being installed between upper cover and lower cover, make like this air do curve in radiator cavity and rotatablely move, the time of contact of prolongation and thermal column, radiator is carried out to sufficient heat exchange.
14, due to the similar pyriform of lampshade external form, LED light source assembly holds curved surface and installs along the thermal column surface of radiator, the luminous of all light sources has low-angle to be superimposed, it is luminous that formation is greater than the lighting angle of 300 degree, it has the advantages that the light emitting anger uniformity is greater than 300 degree, has effectively divided equally luminous intensity.
