Description of drawings
Accompanying drawing constitutes the part of this specification, is used for helping further to understand the present invention.These accompanying drawings illustrate embodiments of the invention, and are used for illustrating principle of the present invention with specification.Identical in the accompanying drawings parts are represented with identical label.Shown in the figure:
Fig. 1 is the three-dimensional exploded view according to lamp socket of the present invention;
Fig. 2 is the sectional view according to lamp socket of the present invention;
Fig. 3 is the sectional view according to lighting device of the present invention.
The specific embodiment
Fig. 1 shows the three-dimensional exploded view according to lamp socket of the present invention.As seen from the figure, this lamp socket comprises housing 1 and the cooling-part 2 that is installed in the housing 1.Housing 1 has flaring perisporium 4, end cap 3 and dividing plate 5.End cap 3 covers on the smaller diameter end A1 of perisporium 4, and dividing plate 5 is arranged in the perisporium 4 abreast with end cap 3.Limit the first cavity R1 that holds cooling-part 2 by end cap 3, dividing plate 5 and the part perisporium 4 that is positioned between the two thus, dividing plate 5 and remaining perisporium 4 limit be used to the second cavity R2 (referring to Fig. 2 and Fig. 3) that holds lamp body 100, and this second cavity R2 has towards the opening in the external world, is the larger diameter end A2 of perisporium 4.Cooling-part 2 is placed in the different cavitys with lamp body 100 with being separated, and by means of 100 large-area covering and the protections of 4 pairs of lamp bodies of perisporium, can prevent that the dust in the external environment from invading in the lamp body 100 in large quantities.
Cooling-part 2 is the fan 8 with rotating shaft 9 at this.The bottom of rotating shaft 9 is fixed on the dividing plate 5, and the top is opened in locating hole 11 mortgage of end cap 3 central authorities, can fan 8 be fixed between end cap 3 and the dividing plate 5 to add the mode of holding thus, and this simple structure is conducive to fan is carried out installation and maintenance.
From Fig. 1 further as seen, in order between the first cavity R1, the second cavity R2 and external environment, to form the air-cooled circulation that air-flow communicates, therefore offer a plurality of second through holes 12 at end cap around locating hole 11, and correspondingly in the circumferential edge zone of dividing plate 5, offer a plurality of first through holes 6.According to the present invention, by driving cooling-part 2, being that fan rotates, can make air-flow pass a plurality of first and second through holes 6,12 respectively in lamp socket inside and enter in the external environment.For air-flow is circulated equably, these first, second through holes 6,12 are evenly distributed.
Fig. 2 shows the sectional view of lamp socket after assembling among Fig. 1.From this figure, can clearly be seen that the position of the first cavity R1 and the second cavity R2.Be provided with the electrical connection section 10 for lamp body 100 in the second cavity R2, this electrical connection section 10 is arranged on protruding of dividing plate 5 on the side of the second cavity R2 and from this side towards larger diameter end A2.Electrical connection section 10 has two electric-conductors 13 that are used for lamp body 100, and these two electric-conductors 13 pass dividing plate 5 and can be connected with the both positive and negative polarity of power line.In this embodiment, electrical connection section 10 is designed for the lamp body 100 that connection for example has the E27 lamp holder, so the inner peripheral surface of electrical connection section 10 is provided with screw thread.But also can be according to the present invention electrical connection section 10 be designed for the lamp body 100 that connection for example has GU lamp holder or other types lamp holder.
Fig. 3 shows according to lighting device of the present invention.This lighting device comprises lamp socket and is installed in lamp body 100 among the second cavity R2 of lamp socket.Lamp body 100 is designed to LED remodeling lamp at this, and has cell-shell 101 and the sidewall 102 that is designed to thermal component as exiting surface.For dustproof, the perisporium 4 of housing 1 surrounds and covers lamp body 100 in large area, and wherein cell-shell 101 stretches out the larger diameter end A2 of perisporium 4 at least in part.Be formed for water conservancy diversion zone 7 that air is flow through between the circumferential profile of circumferential profile, the particularly sidewall 102 of the perisporium 4 of housing 1 and lamp body 100, this water conservancy diversion zone 7 communicates with first through hole, 6 air-flows.Because lamp body 100 can produce a large amount of heats when work, these heats pass through sidewall 102 especially towards water conservancy diversion zone 7 radiation.Therefore for example can guide the air-flow among the second cavity R2 to flow into the first cavity R1 by water conservancy diversion zone 7 by driving cooling-part 2, and and then enter external environment by second through hole 12 on the end cap 3.Because the second cavity R2 is open cavity, therefore advantageously generate the air-cooled circulation in the cavity R2-of the external world-second first cavity R1-external world like this.
In order when not hindering fan 8 to rotate, to give fan 8 and lamp body 100 power supplies, therefore the supply lines that is used for fan 8 and lamp body 100 can be arranged in the rotating shaft 9 that is designed to hollow shaft.This design has also improved the compactedness of lamp socket.Fan 8 can be the fan that is directly driven by dc source in the present invention, also can be the fan that self has transformer.
In addition, because lamp body 100 is arranged in the second cavity R2, therefore in order not influence the optical efficiency of lighting device under the prerequisite that realizes good heat radiating, the circumferential zones towards exiting surface 101 according to the present invention with perisporium 4 is designed to reflecting surface F.By applying reflectorized material at this circumferential zones, the mode that reflecting layer or other are fit to is set realizes reflection.
Be the preferred embodiments of the present invention only below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.All any modifications of doing within the spirit and principles in the present invention, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
