The specific embodiment

In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

See also Fig. 1 and Fig. 2, be respectively partial exploded view of the present utility model and in-built combination schematic diagram.The utility model provides a kind of LED road lamp cap package assembly, comprises that a lampshade 1 and is located at the heat abstractor 2 in this lampshade 1; Wherein:

This lampshade 1 is made of a base 10 and a loam cake 11, its base 10 belows are in order to settle a LED unit 3, this LED unit 3 comprises a circuit board 30 and plural number is located at light emitting diode 31 on this circuit board 30, and the light source that each light emitting diode 31 of LED unit 3 is provided can throw (promptly as shown in Figure 4) towards lampshade 1 below.Base 10 forward and backward two sides are then erect respectively and are formed a shield 12, are cross-placed between two shields 12 by the aforementioned loam cake 11 that slightly is curved arc shape again, on shield 12 pore 120 can be set.

See also shown in Figure 3ly, this heat abstractor 2 is located in this lampshade 1, and comprises a heated sheet 20, at least one heat pipe 21 and a heat sink 22.Wherein, this heated sheet 20 dispels the heat to help LED unit 3 in order to be contacted with on above-mentioned LED unit 3 dorsal surfaces; And the utility model for embodiment in, as shown in Figure 4, this LED unit 3 attaches a heat conducting base 32 on its circuit board 30 dorsal surfaces, and these heat conducting base 32 bottom surfaces groove 320 that can further set to the concave, for imbedding in the groove 320 and ccontaining LED unit 3.

From the above, be concaved with at least one groove 200 on this heated sheet 20, imbed, and described groove 200 is good to be positioned at these heated sheet 20 bottom surfaces, because of pressing close to the thermal source of LED unit 3 for an end of above-mentioned heat pipe 21; In addition, also be concaved with at least one groove 220 on this heat sink 22, imbed for the other end of above-mentioned heat pipe 21, described groove 220 is good to be positioned at these heat sink 22 end faces then, because of than can be away from the thermal source of LED unit 3.Simultaneously, as shown in Figure 1, the loam cake 11 of above-mentioned lampshade 1 is provided with a posting port 110, just can pass through for it with respect to the position of this heat abstractor 2, and establish a cover plate 13 in these posting port 110 loam cakes, and the heat sink 22 of this heat abstractor 2 promptly is attached at this cover plate 13 belows.

After the main elder generation of the utility model is mounted on heat abstractor 2 tops by this cover plate 13, again this heat abstractor 2 is mounted in the lampshade 1 by posting port 110, to make heat abstractor 2 belows contact with the thermal source of LED unit 3, at this moment, relend and establish assembly 14 by plural number as spiral shells such as bolts and run through this cover plate 13 respectively and be located on the heated sheet 20 with spiral shell; And the utility model for embodiment in, this cover plate 13 is provided with for spiral shell and establishes the perforation 130 that assembly 14 runs through, and is provided with for spiral shell in heated sheet 2 and establishes the screw 201 that assembly 14 is screwed into.In addition, also can be provided with the perforation 131 of passing on this cover plate 13, affixed the closing of the two spiral shell contacted corresponding to the screw on the heat sink 22 221 for screw 15.Moreover, when this cover plate 13 is covered on the described posting port 110, also can passes its perforation 132 and be locked on the position on loam cake 11 and the screw 111 of nearly posting port 110 peripheries, to reach the purpose of assembling by screw 16.

In view of the above, as shown in Figure 4, the length that aforementioned spiral shell is established assembly 14 promptly is preset as just can be replaced heated sheet 20 to 3 back sides, LED unit or heat conducting base 32 end faces and contact with it; So, when heat abstractor 2 and cover plate 13 together are assembled on the loam cake 11, the heated sheet 20 that can guarantee this heat abstractor 2 contacts with the thermal source of LED unit 3, and is a kind of dismountable assembling mode, is beneficial in the future if desire is changed the replaceability of the convenience and the part of its inner spare part.

Therefore, by above-mentioned contexture, can obtain the utility model LED road lamp cap package assembly.

Therefore, by the utility model LED road lamp cap package assembly, because described spiral shell is established assembly 14 and can be passed through its by chance enough length, with the heated sheet 20 of heat abstractor 2 is replaced to LED unit 3 state of contact, and borrow each spiral shell to establish assembly 14 and keep this state, so this heat abstractor 2 can form dismountable package assembly by establishing with the group of cover plate 13, although assembling again after the dismounting, also can keep by each spiral shell and establish the contact condition that assembly 14 is kept heated sheet 20 and LED unit 3, and also can be between this heated sheet 20 and LED unit 3 dorsal surfaces, or and heat conducting base 32 end faces between heat-conducting mediums (figure slightly) such as coating one deck such as heat-conducting cream.In addition, the periphery of this heat abstractor 2 in lampshade 1 also can be set up other radiating subassembly 23.

In sum, the utility model is real to be rare innovation and creation product, it really can reach the application target of expection, and the disappearance of solution prior art, because of having novelty and progressive, meet the patent application important document of utility model fully, again so file an application according to Patent Law, would like to ask detailed survey and grant accurate this case patent, to ensure the present utility model people's right.

But, the above only is a preferable possible embodiments of the present utility model, and non-so promptly inflexible limit claim of the present utility model is so the equivalent structure that uses the utility model specification and accompanying drawing content to do such as changes, all in like manner all be contained in the scope of the present utility model, close and give Chen Ming.
