Abstract
Disclosed in the utility model is an LED lamp holder comprising a plastic cylinder body. A copper pin riveting portion is arranged at a closing end of the cylinder body; a platform portion that extends outwardly along the periphery of the body wall is arranged at an opening end; and connecting columns for connecting with a radiator are arranged at the platform. Air cross-ventilation holes that enable the inner cavity space of the cylinder body to be communicated with the external world outside the cavity are arranged at the closing end and the platform portion, wherein the directions of the cross-ventilation holes are identical with the axial direction of the cylinder body. According to the scheme, a problem that heat dissipation at the bottom of a radiator can not be carried out smoothly because heat in a cavity space of a lamp holder can not be dissipated timely and thus the normal service life of an LED lamp bead is influenced in the prior art can be solved.
Description
Technical field:
The utility model relates to field of light fittings, relates in particular to a kind of LED lamp lamp holder.
Background technology:
As everybody knows, LED lamp contains radiator and the lens that serve as Lamp cup conventionally, LED lamp pearl and lamp holder, existing lamp holder has pottery and two kinds, plastics, the structure of Plastic lamp socket is that the closed end at cylinder is provided with copper pin caulking part, openend is provided with along the outward extending platform part of body wall circumference, on platform, be provided with the joint pin for being connected with radiator, its advantage is that production technology is simple, cost is low, not enough place is the bottom heat radiation that is unfavorable for radiator, its reason is, during use, described lamp holder is closely connected on the bottom of radiator, its cavity space forms the power line hole because of on base plate of radiator to communicate with the inner chamber of radiator, the temperature that causes the environment temperature of this cavity space to follow lumen of radiator rises, and the thermal conductivity factor of plastics is not high, so exist the heat in this cavity space not distribute in time, cause the bottom heat radiation of radiator to be obstructed, have influence on the problem of LED lamp pearl ordinary life.
Utility model content:
In order to make up the problems referred to above, the utility model is to provide a kind of LED lamp lamp holder, and compared with prior art, this lamp holder is provided with cross-ventilation hole, and its technical scheme is as follows:
A lamp lamp holder, contains plastic cylinder body, and the closed end of described cylinder is provided with copper pin caulking part, and openend is provided with along the outward extending platform part of body wall circumference, is provided with the joint pin for being connected with radiator on platform; In addition, described closed end and platform part are provided with and can make the intracavity space of cylinder and the cross-ventilation hole that chamber is interlinked to the outside, and the direction of described convection holes is axially identical with cylinder.
During use, after described lamp holder is closely connected on the bottom of radiator, now, the intracavity space of described cylinder is formed and communicates with the intracavity space of radiator by the power line hole on base plate of radiator, and but the intracavity space of cylinder communicates with the external world by described convection holes, and the convection holes being separately positioned in described closed end and platform part forms, the circulating window of lower two kinds of differing heights, so when cavity temperature raises, very easily produce thermal convection current with outside air, to improving heat Quick diffusing in chamber, restrain on lamp pearl operating ambient temperature and rise to good effect.
The beneficial effects of the utility model are: closed end and the platform part of described lamp holder are provided with convection holes, having solved prior art can not distribute in time because of the heat in burner cavity body space, cause the bottom heat radiation of radiator to be obstructed, have influence on the problem of LED lamp pearl ordinary life.
Accompanying drawing explanation:
1, Fig. 1 is the structural representation (top view) of described LED lamp lamp holder;
2, Fig. 2 is the cutaway view of A-A in Fig. 1;
The specific embodiment:
Below in conjunction with accompanying drawing, the novel described LED lamp lamp holder of this reality is further described.
With reference to figure 1, Fig. 2, as shown in these figures, described LED lamp lamp holder, contain plastic cylinder body 1, the closed end of described cylinder is provided with copper pin caulking part 6, and openend is provided with along the outward extending platform part 4 of body wall circumference, is provided with the joint pin 5 for being connected with radiator on platform; In addition, described closed end and platform part are provided with and can make the intracavity space of cylinder and the cross-ventilation hole 2 that chamber is interlinked to the outside, and the direction of described convection holes 2 is axially identical with cylinder 1.
