The specific embodiment
Refer to Fig. 1 to Fig. 4, the schematic diagram that Fig. 1 is LED lamp structure of the present utility model; Fig. 2 is the generalized section of LED lamp structure of the present utility model; Fig. 3 is the schematic diagram of the substrate of LED lamp structure of the present utility model; Fig. 4 is another schematic diagram of the substrate of LED lamp structure of the present utility model.As shown in the figure, LED lamp structure 1 comprises substrate 11, heat-conducting layer 12, heat conduction cylinder 13, a plurality of luminescence unit 14 and Control Component 15.Substrate 11 has a plurality of holes 111.Heat-conducting layer 12 covers the two sides of substrate 11 and the inner edge of a plurality of hole 111, and heat-conducting layer 12 can be copper layer or the good nonwoven fabric from filaments of other thermal conductivity.Heat conduction cylinder 13 is hollow-core construction, and to form accommodation space 131, substrate 11 is arranged on one end of heat conduction cylinder 13; Wherein the shape of heat conduction cylinder 13 can be the cylinder of cylinder, square column or other shapes, and heat conduction cylinder 13 may further be metal cartridge, as copper cylinder, yet, above are only example, with above-mentioned example, do not limit.A plurality of luminescence units are laid in the two sides of substrate 11 for 14 minutes.Control Component 15 is located among accommodation space 131, and is electrically connected each luminescence unit 14.
Wherein, the material of substrate 11 is not limited at this, yet, can with heat-conducting layer 12 mutually insulateds, if further contemplate manufacturing cost, substrate 11 preferably can be glass fibre basal plate or bakelite, but not as limit.
From the above, a plurality of holes 111, conduct to one of substrate 11 surperficial heat outside another surface after heat-conducting layer 12 coverage hole 111 inner edges except making, and hole 111 can also conveniently be laid a plurality of luminescence units 14 on the two sides of substrate 11.In more detail, the luminescence unit 14 that is located at the two sides of substrate 11 can interconnect by passing through hole 111; Also or relatively heat conduction cylinder 13 be arranged on a plurality of luminescence units 14 of the one side of substrate 11 can be through hole 111 another side to substrate 11, to connect Control Component 15.In other words, LED lamp structure 1 of the present utility model can be coated with by a plurality of inner edges the hole 111 of heat-conducting layer 12, increases the heat-conducting effect of LED lamp structure 1, and is reduced in the difficulty that luminescence unit 14 is laid on substrate 11 two sides.
In addition, due to the row of luminescence unit 14 establishes should be neat, corresponding heat conduction cylinder 13 is located at a plurality of luminescence units 14 of the one side of substrate 11 can be around the outer rim proper alignment of heat conduction cylinder 13.And a plurality of luminescence units 14 of another side also can substrate 11 or being shaped as according to arranging of heat conduction cylinder 13.Whereby, make a plurality of luminescence unit 14 marshallings; The brightness that in addition, can also make light source irradiate is even and angle is consistent.
Subsidiary one carries, and LED lamp structure 1 of the present utility model also comprises lampshade 16 and radiating seat 17.Lampshade 16 can be coated substrate 11 and heat conduction cylinder 13, and therefore, the shape size of substrate 11 and heat conduction cylinder 13 should meet lampshade 16 shape sizes, and vice versa.One end of radiating seat 17 connects the openend of lampshade 16 and the other end of heat conduction cylinder 13, and wherein radiating seat 17 can be metal and makes, as copper, aluminium.
Therefore, the heat that the substrate 11 of LED lamp structure 1 of the present utility model produces with respect to a plurality of luminescence units 14 in the one side of heat conduction cylinder 13, heat-conducting layer 12 conduction of this face by covering surfaces 11, and through covering the heat-conducting layer 12 of a plurality of hole 111 inner edges, conduct heat to the heat-conducting layer 12 of the another side of covered substrate 11; Finally, then the heat conduction cylinder 13 being connected by the heat-conducting layer 12 of the another side of covered substrate 11 by the torrid zone to radiating seat 17, and then by heat radiation to LED lamp structure 1.
Yet, for making the elements such as substrate 11, heat conduction cylinder 13 can be suitably and be reasonably placed in lampshade 16.This lampshade 16 can comprise the first lampshade 161 and the second lampshade 162; The opening inner edge of the first lampshade 161 can cave inward and form support portion 1611, with the opening of bearing substrate 11, the second lampshades 162, can be bonded with each other with the opening of this first lampshade 161.Yet, above are only the example of the present embodiment, not as limit.
In general, its Control Component of LED lamp structure is on the market located on substrate, and Control Component and each luminescence unit and connection line thereof are more and assorted, therefore, cause substrate to seem not attractive in appearance in a jumble.Therefore, the lampshade of LED lamp structure often corresponds to translucent lampshade, to avoid directly seeing inner substrate and related elements thereof from lampshade outside.
For this reason, Control Component 15 of the present utility model can be placed in the accommodation space 131 of heat conduction cylinder 13, and be located at above-mentioned one end of radiating seat 17, because the two ends of heat conduction cylinder 13 are connected with substrate 11 and radiating seat 17 respectively, therefore, accommodation space 131 forms confined space, and then cannot see Control Component 15 and circuit and element in accommodation space 131 in LED lamp structure 1 outside; And further, Control Component 15 has electrode unit 151 (positive and negative two electrodes of take are in the present embodiment example), electrode unit 151 can be located on substrate 11, and each luminescence unit 14 just can be by being electrically connected electrode unit 151, to set up the annexation between luminescence unit 14 and Control Component 15; And only by electrode unit 151, on substrate 11, for luminescence unit 14, connect.Whereby, simplify the circuit of substrate 11 and the configuration of related elements; Corresponding above-mentioned, lampshade 16 can adopt Transparent lamp shade, because lampshade 16 is Transparent lamp shade, thus the increase of light penetration rate, and then the brightness of illumination of LED lamp structure 1 improves thereupon.
It should be noted that heat conduction cylinder 13 of the present utility model can be connected and fixed substrate 11 and radiating seat 17 by a plurality of fixtures 132 (as screw); Yet, above are only example, it can by other means or mix various ways and connect, for example, put after glue connects and with screw, lock, at this, is not limited.
In addition, heat conduction cylinder 13 can have reflector layer 133, and reflector layer 133 is the outer surface of coated heat conduction cylinder 13, and reflector layer 133 may further be chromium layer, but not as limit; The light refraction that reflector layer 133 can be launched contiguous luminescence unit 14, strengthens the irradiating angle of LED lamp structure 1 whereby; For light angle is strengthened, and brightness of illumination is even, and heat conduction cylinder 13 preferably can be cylinder, coordinates the reflector layer 133 of outer surface, and then obtains good effect.
Take a broad view of above-mentioned; seeing through LED lamp structure of the present utility model clever thought in design changes; it is by a plurality of holes on substrate; and cooperation heat-conducting layer; so that the heat that the luminescence unit on substrate two sides produces heat loss through conduction effectively; for prior art institute can not and person; really reached the effect improved of wish; and also non-those skilled in the art easily expect; its progressive possessing, practicality; the application important document that has met patent therefore proposes patent application, to being protected accordingly in accordance with the law.
