Description
Technical field
the present invention relates to a kind of novel LED lamp pearl.
Background technology
Existing LED illuminating lamp on current domestic and international market, its lamp pearl, power supply is holistic structure to lamp housing, because the lamp pearl of existing LED lamp is all to adopt lamp pearl positive and negative to be extremely welded on the front of aluminium base, aluminium base source of welding current wire, when mounted LED lamp, the reverse side of aluminium base coagulates slurry by coated with thermally conductive and contacts with lamp socket (lamp housing) inner panel as silicone grease etc., this complex manufacturing technology, and as because damaging integral LED lamp, light emitting diode (LED) or a small components can not use, all scrap, and the cost of aluminium base accounts for sizable ratio in whole LED lamp, thereby cause the very large waste of material, cause the price of LED lamp high all the time, simultaneously, because the efficiency of LED lamp is easily subject to temperatures involved and sharply declines, hotlyyer after waste electric power, also produce, make temperature further rise, easily form vicious circle, except waste electric power, also can shorten the life-span of LED, therefore good heat radiation also has great motive force for applying of LED lamp, and existing LED lamp pearl adopts aluminium base as electric substrate the effect of dispelling the heat by the solidifying slurry of heat conduction applying not ideal enough.
Summary of the invention
Object of the present invention is to provide that a kind of simple in structure, lamp pearl body replaceable, cost of manufacture are low, the Novel LED lamp bulb of perfect heat-dissipating.
LED lamp pearl of the present invention, comprise lamp pearl body, described lamp pearl body comprises luminescence chip, silica-gel lens, cylindrical insulation plastic cement and positive and negative electrode bonding pad, the below of described luminescence chip is provided with chip cooling pedestal, described positive and negative electrode bonding pad is connected by conductive filament with luminescence chip, it is characterized in that: this LED lamp pearl also comprises that one for installing the lamp bulb seat of lamp pearl body, described lamp bulb seat comprises lamp bulb seat inner casing and lamp bulb seat shell, and the inner surface of described lamp bulb seat inner casing is covered with tapped positive and negative electrode contact plate; The periphery of described cylindrical insulation plastic cement is covered with is with externally threaded positive and negative electrode guide plate, and described positive and negative electrode guide plate is connected with positive and negative electrode bonding pad respectively; Described lamp pearl body is connected by internal and external screw thread with lamp bulb seat.
Between described lamp bulb seat inner casing and lamp bulb seat shell, be provided with stabilizing spring, the lower end of described lamp bulb seat inner casing is provided with step, and upper end is provided with guide slot, and the upper end of described lamp bulb seat shell is provided with the directional bond corresponding with guide slot.
On described positive and negative electrode guide plate and positive and negative electrode contact plate, be equipped with pole plate fixing hole.
Described lamp bulb seat shell is provided with lamp bulb seat fixing hole.
The cylindrical insulation plastic cement of described lamp pearl body is provided with the tooling hole for revolving light pearl body.
Described chip cooling pedestal abuts on lamp housing heat radiation inner panel.
Beneficial effect of the present invention is:
1, changed the unitary structure of traditional LED lamp pearl completely, what LED lamp pearl was designed to comprise lamp pearl body and lamp bulb seat can separation structure, lamp pearl body is separated with the rotatable dismounting of lamp bulb seat, in daily life in case of lamp pearl body or lamp bulb seat have been broken, directly pull down and more renew lamp pearl body or new lamp bulb seat, greatly reduce the use cost of LED lamp;
2, optimize and omitted aluminium base, on lamp bulb seat of the present invention, adopt stabilizing spring can make the chip cooling pedestal of lamp pearl body surely be attached on lamp housing heat sink, make heat radiation more direct, radiating effect is better, thereby also relatively extended the service life of LED lamp pearl, and do not use aluminium base to save raw material yet, and be conducive to environmental protection, reduced the production cost of LED lamp.
