Abstract
The utility model discloses a heat radiating lamp cup, which comprises a lamp holder, a drive power supply which is installed inside the lamp holder, a cup-shaped glass shell which is connected with the lamp holder, a glass cover which is buckled onto the cup-shaped glass shell, a lamp panel and a light emitting diode (LED) which is welded onto the lamp panel, wherein the inner wall of the cup-shaped glass shell is fixedly provided with a ring-shaped heat radiating platform, the lamp panel is made of an aluminum substrate, and the lamp panel is fixed on the heat radiating platform through an aluminum ring. The heat radiating lamp cup has good heat radiation performance and long service life.
Description
Technical field
The utility model relates to a kind of heat radiation Lamp cup.
Background technology
In traditional LED Lamp cup structure, the lamp plate that directly will be welded with LED is bonded on the glass shell.Because lamp plate is phenolic aldehyde base (or epoxy radicals) sheet material, and the thermal conductivity of phenolic aldehyde base (or epoxy radicals) is very low, scatters after the last heat of LED is difficult to, and has accelerated the light decay of LED, has had a strong impact on the LED life-span
The utility model content
The utility model purpose is: to the problems referred to above, a kind of heat radiation Lamp cup is provided, this Lamp cup has good thermal diffusivity, long service life.
The technical scheme of the utility model is: a kind of heat radiation Lamp cup; Comprise lamp holder, be contained in lamp holder interior driving power, the cup-shaped glass shell that links to each other with lamp holder, be buckled in glass cover, the lamp plate on the cup-shaped glass shell and be welded in the LED on the lamp plate; Be fixed with the cooling platform of annular on the inwall of said cup-shaped glass shell; Said lamp plate adopts aluminium base to process, and this lamp plate is fixed on the said cooling platform through an aluminium circle.
Said cooling platform is an aluminum.
Be equipped with heat conductive silica gel between said lamp plate and the cup-shaped glass shell.
The utility model has the advantages that: the heat of LED can pass to cup-shaped glass shell through lamp plate and cooling platform on the utility model, sheds heat through cup-shaped glass shell again.Improved the heat dispersion of LED greatly.Reduce the LED light decay, prolonged the life-span of LED
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to introduce:
Fig. 1 is the stereogram of the utility model embodiment;
Fig. 2 is the explosive view of the utility model embodiment;
Wherein: 1-lamp holder, the cup-shaped glass shell of 2-, 3-driving power, 4-lamp plate, 5-LED, 6-glass cover, 7-cooling platform, 8-aluminium circle.
The specific embodiment
As depicted in figs. 1 and 2, the Lamp cup of present embodiment comprises lamp holder 1, driving power 3, cup-shaped glass shell 2, glass cover 6, lamp plate 4, LED5, and wherein: driving power 3 is contained in lamp holder 1 inside, and cup-shaped glass shell 2 is connected on the lamp holder 1, and LED5 is welded on the lamp plate 4.
Lamp plate 4 in this example adopts aluminium base to process, thereby makes this lamp plate have good heat conductivility.Be fixed with the aluminum cooling platform 7 of an annular on the inwall of cup-shaped glass shell 2, said lamp plate 4 is fixed on (lamp plate is stuck on the cooling platform through the aluminium circle) on this cooling platform 7 through an aluminium circle 8.
In order to let the heat of LED5 be delivered on the cup-shaped glass shell 2 by lamp plate 4 better, this example is equipped with heat conductive silica gel between lamp plate 4 and cup-shaped glass shell 2.
During work, LED5 has two heat dissipation path.Article one, heat dissipation path (main heat dissipation path) is: LED-lamp plate-heat conduction platform-cup-shaped glass shell; The second heat dissipation path is: LED-lamp plate-cup-shaped glass shell.Lamp plate 4 all has good heat conductivility with heat conduction platform 7, and cup-shaped glass shell 2 has good heat dispersion, has lowered the temperature of this Lamp cup greatly.
Certainly, the foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is the content that lets people can understand the utility model and implements according to this, can not limit the protection domain of the utility model with this.All equivalent transformation or modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection domain of the utility model.
