Abstract
The invention discloses a ventilating structure of a lamp. The ventilating structure comprises a lamp body, a light source arranged in the lamp body, and a light collecting cup which is used for covering the light source, wherein a light transmitting plate is arranged at the opening of the light collecting cup; the light collecting cup and the light transmitting plate are fixed on the lamp body by using a lamp holder connector; a plurality of lug bosses are arranged on the circumference of the inner side of the lamp holder connector; the light transmitting plate is clamped on the lug bosses; a plurality of through holes are formed in the circumference of the lamp holder connector; the through holes are used for ventilation by corresponding to gaps between the lug bosses; the opening edge of the light collecting cup leans against one side surface of each lug boss, so that the opening edge of the light collecting cup is isolated from the light transmitting plate; the internal space of the light collecting cup is directly communicated with the through holes so as to realize ventilation. Hot air sealed in the light collecting cup can flow out of the corresponding through holes in the lamp holder connector through the gaps between the lug bosses so as to form air convection, and thus rapid heat radiation is realized.
Description
Technical field
The present invention relates to light fixture, particularly a kind of ventilating structure of light fixture.
Background technology
Along with the development of illuminating industry, LED lamp is also more and more general, but LED caloric value is high, need good radiating effect, otherwise can affect service time, have now the light fixture that light source is sealed by diffuser by lamp such as Ceiling light, track lamp etc., its heat dissipation problem is never well solved, cause overheated and reduce service time, wasting resource like this.
Therefore, how realizing above-mentioned light fixture can have well ventilative heat radiation to be technical problem urgently to be resolved hurrily in the industry.
Summary of the invention
Main purpose of the present invention is to provide a kind of ventilating structure of light fixture, and being intended to realize light fixture can have well ventilative, radiating effect, extends the service time of light fixture, reduces the waste rate of resource.
The present invention proposes a kind of ventilating structure of light fixture, comprise the light source in lamp body, described lamp body, the prefocus cup covered on described light source, described prefocus cup opening part arranges a light transmission piece, is fixed on described lamp body with a lamp holder connector by described prefocus cup, light transmission piece; Described lamp holder connector inside circumference is provided with some boss, and described light transmission piece is stuck on described boss, and described lamp holder connector is circumferentially provided with some through holes, and described through hole correspondence communicates ventilative with the space between described some boss; The edge of opening of described prefocus cup withstands on a side of described boss, makes the spaced apart of the edge of opening of described prefocus cup and described light transmission piece, and in described prefocus cup, space is directly communicated with described through hole and breathes freely.
Preferably, the width of described boss is greater than the thickness of described light transmission piece.
Preferably, described lamp holder connector is fixedly connected with described lamp body by screw thread.
The ventilating structure of light fixture of the present invention can be used on various light fixture, such as track lamp, Ceiling light etc. other need the light fixture of enclosed light source, enclosed light source just needs the ventilating structure using this light fixture just can reach ventilative thermolysis.The hot gas be sealed in prefocus cup can be flowed out by through hole corresponding on the interstitial flow between boss to lamp holder connector, and the air outside lamp also can flow in prefocus cup by through hole, forms cross-ventilation, makes heat radiation fast.

Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, one embodiment of the ventilating structure of a kind of light fixture of the present invention is proposed, comprise the light source 2 in lamp body 1, described lamp body 1, the prefocus cup 3 covered on described light source 2, described prefocus cup 3 opening part arranges a light transmission piece 4, is fixed on described lamp body 1 with a lamp holder connector 5 by described prefocus cup 3, light transmission piece 4; Described lamp holder connector 5 inside circumference is provided with some boss 6, and described light transmission piece 4 is stuck on described boss 6, and described lamp holder connector 5 is circumferentially provided with some through holes 7, and described through hole 7 correspondence communicates ventilative with the space 8 between some boss 6; The edge of opening of described prefocus cup 3 withstands on a side 61 of described boss 6, makes the edge of opening of described prefocus cup 3 and the spaced apart of described light transmission piece 4, and in described prefocus cup 3, space is directly communicated with ventilative with described through hole 7.The hot gas be sealed in prefocus cup 3 can be flow to through hole 7 corresponding on lamp holder connector 5 and flow out by the space 8 between boss 6, air outside lamp also can flow in prefocus cup 3 by through hole 7, form cross-ventilation, make heat radiation fast, the service life of light fixture can be extended.
The width of described boss 6 is greater than the thickness of described light transmission piece 4, when the edge of opening of such prefocus cup 3 withstands on a side of boss 6, also has certain distance to form space and be convenient to air circulation between prefocus cup 3 and light transmission piece 4.Described lamp holder connector 5 is fixedly connected with described lamp body 1 by screw thread 9.The light transmission piece 4 that described light transmission piece 4 can be made for sheet glass, quartz plate, plastic sheet or other light transmissive material.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure transformation utilizing description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
