Description
Technical field
The utility model relates to field of illuminating device, refer in particular to a kind of LED lamp cup conducive to height heat dissipation.
Background technique
LED light source is that a kind of combined light source constituted on one piece of circuit substrate is integrated in using LED lamp bead, with energy consumption
The features such as low, fever is low, small in size, and light efficiency is high, if radiating condition is good, service life will be far longer than conventional domestic light
Source, since LED light source is a kind of cold light source, it is a kind of green energy resource that its appearance, which has been linked closely environmental protection and energy-efficient theme,
The light sources such as the incandescent lamp and fluorescent lamp for being suitble to substitution traditional.
Although the fever of LED lamp bead is extremely low, its heat has all passed to circuit substrate by pin, and quantity is more
LED lamp bead after powering on and continuing for some time, considerable heat still can be generated, if this partial heat is unable to get effectively
It distributes, still can threaten to circuit substrate and power circuit.Even under serious situation, the high temperature of accumulation can puncture circuit
Plate causes lamps and lanterns to damage；And the closer lamps and lanterns in interval can be influenced each other due to heat dissipation, the structure size of LED lamp itself compared with
It is small, if absorbing a large amount of external heat, can also large effect be generated to lamps and lanterns.Currently, being mostly directly logical on the market
It crosses PC lamp housing outwardly to radiate, radiating efficiency is low, is unfavorable for the service life of lamps and lanterns.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of LED lamp cup conducive to height heat dissipation, by closing aluminium
Golden shell body is directly connected to lamp cap, and heating conduction is high, to be transferred to lamp holder, in air, realizes physics heat dissipation, directly reduction lamp
The heat of tool, heat dissipation performance further increase, to extend the service life of lamps and lanterns.
The utility model is realized in this way: a kind of LED lamp cup conducive to height heat dissipation, including lamp cap, PC shell, aluminium alloy
Shell, inner cavity retainer ring and aluminum substrate, the PC shell and the Al-alloy casing are hollow up-small and down-big horn-like shell,
The Al-alloy casing is set on the PC case inside wall, and the lower ending opening of the Al-alloy casing is located in PC shell,
Upper end opening extends PC shell upper outer, connect with the lamp cap above PC shell, and the inner cavity retainer ring is arranged in aluminium alloy
The inner sidewall edge of shell upper end opening；The aluminum substrate be set to inside the PC shell lower ending opening and with the Al alloy shell
The lower ending opening of body contacts.
Further, a plurality of positioning circular grooves are provided on the upper end opening lateral wall of the Al-alloy casing.
Further, two accentric support columns are set on the inner cavity retainer ring.
Utility model has the advantages that heating conduction is high, to pass by the way that Al-alloy casing and lamp cap to be directly connected to
It is handed to lamp holder, in air, realizes physics heat dissipation, the directly heat of reduction lamps and lanterns, heat dissipation performance further increases, to extend lamp
The service life of tool.
Detailed description of the invention
The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the utility model overall schematic；
Fig. 2 is the utility model section schematic diagram；
Drawing reference numeral explanation:
1, lamp cap 2, PC shell
3, Al-alloy casing 4, inner cavity retainer ring

Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
The utility model is further described with specific embodiment with reference to the accompanying drawing.
It please refers to shown in Fig. 1 and Fig. 2, a kind of LED lamp cup conducive to height heat dissipation, including lamp cap 1, PC shell 2, Al alloy shell
Body 3, inner cavity retainer ring 4 and aluminum substrate 7, the PC shell 2 and the Al-alloy casing 3 are hollow up-small and down-big horn-like shell
Body, the Al-alloy casing 3 are set on 2 inner sidewall of PC shell, and the lower ending opening of the Al-alloy casing 3 is located at PC shell
In body 2, upper end opening extends 2 upper outer of PC shell, connect with the lamp cap 1 of 2 top of PC shell, the inner cavity retainer ring 4 is set
It sets at the inner sidewall edge of 3 upper end opening of Al-alloy casing；The aluminum substrate be set to inside 2 lower ending opening of PC shell and with
The lower ending opening of the Al-alloy casing 3 contacts.
To enable aluminum alloy to shell 3 and lamp cap 1 by the stronger of interference fit, safety, the Al-alloy casing 3 it is upper
A plurality of positioning circular grooves 5 are provided on end opening lateral wall.
For better fixed power source plate, two accentric support columns 6 are set on the inner cavity retainer ring 4.
Working principle of the utility model is: the fever of LED lamp bead, its heat has all passed to aluminum substrate 7 by pin,
Aluminum substrate 7 is contacted by the aluminium of outer ring with Al-alloy casing 3, is being connected by Al-alloy casing 3 with lamp cap 1, however lamp cap 1 and
Lamp holder is connected, therefore heat is gradually transmitted to outside lamp, realizes physics heat dissipation.
The designing points of the utility model are that by the way that Al-alloy casing 3 and lamp cap 1 to be directly connected to, heating conduction is high,
To be transferred to lamp holder, in air, physics heat dissipation is realized, the directly heat of reduction lamps and lanterns, heat dissipation performance further increases, thus
Extend the service life of lamps and lanterns.
