Abstract

The utility model discloses an LED bulb lamp compact in structure. The LED bulb lamp comprises a glass bulb, a rear cover, a power source, a radiator and an aluminum substrate with LEDs, wherein the aluminum substrate is installed in the glass bulb, the power source and the radiator are installed in an inner cavity of the rear cover, the glass bulb and the aluminum substrate are fixed to a middle plate, and the bottom of the middle plate compresses the radiator and is fixedly connected with the rear cover; the radiator comprises cooling fins and a hollow fixing plate, the cooling fins are evenly distributed in the fixing plate at equal intervals, the power source is located in the center of the cooling fins, and the outer wall of the fixing plate is correspondingly matched with the inner cavity of the rear cover in shape. The glass bulb and the aluminum substrate are fixed to the middle plate, the radiator is compressed through the middle plate and then fixed in the rear cover, due to the fact that the shape of the outer wall of the fixing plate is the same as that of the inner cavity of the rear cover, after the outer wall of the fixing plate is tightly matched with the inner cavity of the rear cover, the LED bulb lamp is more compact in structure and convenient to assemble and has the advantages of being reasonable in structure and convenient to produce compared with the prior art.

Description

A kind of LED bulb lamp of compact conformation

[technical field]

The utility model relates to technical field of lighting fixtures, particularly a kind of LED bulb lamp of compact conformation.

[background technology]

At present, realizing carbon reduction, green illumination cry surging period, incandescent lamp is eliminated just gradually, the substitute is the novel green lighting source take LED bulb lamp as representative.

The LED bulb lamp of prior art generally comprises glass envelope, with emitting led aluminium base, power supply and bonnet, aluminium base is arranged in glass envelope, power supply is arranged in the inner chamber of bonnet, the bottom of bonnet connects lamp holder, owing to forming, parts are more, make assembly technology more complicated, for some ball bulb convenient for assembly has expanded the volume of bonnet, simultaneously in order to guarantee radiating effect good in LED bulb lamp, in bonnet, add radiator, but in order to coordinate the installation of radiator, need further to expand the inner chamber of bonnet, make structure compact not, improve production cost.

[utility model content]

The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of LED bulb lamp of compact conformation, can strengthen reasonable structure, convenient for assembly and production.

For achieving the above object, the utility model proposes a kind of LED bulb lamp of compact conformation, comprise glass envelope, bonnet, power supply, radiator and with emitting led aluminium base, described aluminium base is arranged in glass envelope, described power supply and radiator are arranged in the inner chamber of bonnet, glass envelope and aluminium base are all fixed on middle plate, the bottom of described middle plate compresses radiator and is connected and fixed with bonnet, described radiator comprises the fixed head of radiating fin and hollow, radiating fin interval is evenly distributed in fixed head, power supply is positioned at the center of radiating fin, the shape of the outer wall of described fixed head coordinates corresponding with the inner chamber of bonnet.

As preferably, on the bottom end face of described middle plate, be provided with the raised line that is divergent shape, between two adjacent raised lines, form thermovent, on bonnet, offer ventilating opening, the passage of described ventilating opening through between adjacent two radiating fins is communicated with thermovent.

As preferably, described power supply is electrically connected with aluminium base through wire.

As preferably, described bonnet bottom is bolted and fixed with lamp holder.

As preferably, described lamp holder is screw type or buckle-type lamp holder.

The beneficial effects of the utility model: the utility model is by being fixed on glass envelope and aluminium base on middle plate, radiator is fixed in bonnet after being compressed by middle plate, because the shape of fixed head outer wall of radiator is identical with the inner chamber of bonnet, after fixed head outer wall and rear cover cavity closely cooperate, make the utility model structure compacter, easy to assembly, compared with prior art, the utlity model has advantage rational in infrastructure, convenient for production.

Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.

In figure: 1-glass envelope, 2-bonnet, 3-power supply, 4-radiator, 5-are emitting led, plate, 8-radiating fin, 9-fixed head, 10-raised line, 11-thermovent, 12-ventilating opening, 13-passage, 14-wire, 15-lamp holder in 6-aluminium base, 7-.

[specific embodiment]

Consult Fig. 1, Fig. 2 or Fig. 3, the utility model comprises glass envelope 1, bonnet 2, power supply 3, radiator 4 and with emitting led 5 aluminium base 6, described aluminium base 6 is arranged in glass envelope 1, described power supply 3 and radiator 4 are arranged in the inner chamber of bonnet 2, glass envelope 1 and aluminium base 6 are all fixed on middle plate 7, the bottom of described middle plate 7 compresses radiator 4 and is connected and fixed with bonnet 2, described radiator 4 comprises the fixed head 9 of radiating fin 8 and hollow, radiating fin 8 intervals are evenly distributed in fixed head 9, power supply 3 is positioned at the center of radiating fin 8, the shape of the outer wall of described fixed head 9 coordinates corresponding with the inner chamber of bonnet 2, on the bottom end face of described middle plate 7, be provided with the raised line 10 that is divergent shape, between two adjacent raised lines 10, form thermovent 11, on bonnet 2, offer ventilating opening 12, described ventilating opening 12 is communicated with thermovent 11 through the passage 13 of 8 of adjacent two radiating fins, described power supply 3 is electrically connected with aluminium base 6 through wire 14, described bonnet 2 bottoms are bolted and fixed with screw lamp holder 15.

Operation principle of the present utility model: the utility model is by being fixed on glass envelope 1 and aluminium base 6 on middle plate 7, radiator 4 is fixed in bonnet 2 after being compressed by middle plate 7, because the shape of fixed head 9 outer walls of radiator 4 and the inner chamber of bonnet 2 are identical circular-arc, fixed head 9 outer walls and bonnet 2 inner chambers can closely cooperate, because radiating fin 8 intervals in radiator 4 are evenly distributed in fixed head 9, radiating fin 8 surrounds a cavity in fixed head 9, this cavity can be used for installing power supply 3, power supply 3 can be realized effectively heat radiation by radiating fin around 8, not only extend the service life of power supply 3, and can give emitting led 5 good working environment is provided, extend the illumination life-span, by the raised line 10 that is divergent shape is set on the bottom end face at middle plate 7, between two adjacent raised lines, form thermovent 11, on bonnet 2, offer after ventilating opening 12, ventilating opening 12, the passage 13 that radiating fin is 8, thermovent 11 will be interconnected, the heat that is arranged in bonnet 2 and glass envelope 1 is dispersed into external environment condition smoothly, effectively reduce the temperature of emitting led 5 working environments, directly be connected with aluminium base 6 with wire 14, realize non-isolated power supply, improve Electrical Safety.
