Abstract

The utility model discloses an LED bulb lamp high in heat dissipation performance. The LED bulb lamp comprises a glass bulb, an LED, an aluminum substrate, a power source, a heat dissipation device and a rear cover, wherein the glass bulb is fixedly connected with the rear cover through a middle plate, protrusive strips are arranged on the end face of the bottom of the middle plate in a divergent shape, a heat dissipation port is formed between every two protrusive strips, and an inner cavity of the rear cover is communicated with the external environment through the heat dissipation ports. The glass bulb and the aluminum substrate with the LED are fixedly connected through the middle plate and the rear cover, the heat dissipation ports are formed in the end face of the bottom of the middle plate and dissipate heat in the rear cover and the glass bulb to the external environment, temperature of the working environment of the LED is effectively reduced, service life is prolonged, and compared with the prior art, the LED bulb lamp is more reasonable in structure and better in heat dissipation effect.

Description

A kind of LED bulb lamp of high-cooling property

[technical field]

The utility model relates to technical field of lighting fixtures, particularly a kind of LED bulb lamp of high-cooling property.

[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, emitting led, aluminium base, power supply, radiator and bonnet, emitting led being fixed on aluminium base, aluminium base is arranged in glass envelope, power supply and radiator are arranged in the inner chamber of bonnet, the bottom of bonnet connects lamp holder, in the application of LED light source, emitting led light decay and its node operating temperature have direct relation, the operating temperature that how to reduce node just becomes the light source reliability of assurance LED bulb lamp and the key of working life, current LED bulb lamp is enclosed unreasonable structure, make radiating efficiency poor, for the radiating effect having reached, often adopt the mode that strengthens radiator surface area, but the weight that the consequence of doing is like this radiator increases, also improved 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 high-cooling property, can strengthen reasonable structure, improves overall heat dispersion, increases the service life.

For achieving the above object, the utility model proposes a kind of LED bulb lamp of high-cooling property, comprise glass envelope, emitting led, aluminium base, power supply, radiator and bonnet, described emitting led being fixed on aluminium base, aluminium base is arranged in glass envelope, described power supply and radiator are arranged in the inner chamber of bonnet, the bottom of bonnet is provided with lamp holder, in described glass envelope warp, plate and bonnet are connected and fixed, 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, described thermovent is communicated with the inner chamber of bonnet with external environment condition.

As preferably, on described bonnet, offer ventilating opening.

As preferably, described ventilating opening is connected with the thermovent of middle plate.

As preferably, described radiator embeds and is fixed in bonnet.

As preferably, described lamp holder and bonnet are spirally connected fixing.

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

The beneficial effects of the utility model: the utility model is by being connected and fixed by glass envelope with plate and bonnet in emitting led aluminium base warp, on the bottom end face of middle plate, thermovent is set, thermovent by the dissipation of heat that is arranged in bonnet and glass envelope to external environment condition, effectively reduce the temperature of emitting led working environment, increase the service life, compared with prior art, the utility model structure is more reasonable, and radiating effect is stronger.

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

[accompanying drawing explanation]

Fig. 1 is structural representation of the present utility model;

Fig. 2 is decomposing schematic representation of the present utility model.

In figure: 1-glass envelope, 2-are emitting led, plate, 9-raised line, 10-thermovent, 11 ventilating openings, 12-wire in 3-aluminium base, 4-power supply, 5-radiator, 6-bonnet, 7-lamp holder, 8-.

[specific embodiment]

Consult Fig. 1 and Fig. 2, the utility model comprises glass envelope 1, emitting led 2, aluminium base 3, power supply 4, radiator 5 and bonnet 6, described emitting led 2 are fixed on aluminium base 3, aluminium base 3 is arranged in glass envelope 1, described power supply 4 and radiator 5 are arranged in the inner chamber of bonnet 6, the bottom of bonnet 6 is provided with lamp holder 7, in described glass envelope 1 warp, plate 8 is connected and fixed with bonnet 6, on the bottom end face of described middle plate 8, be provided with the raised line 9 that is divergent shape, between two adjacent raised lines 9, form thermovent 10, described thermovent 10 is communicated with the inner chamber of bonnet 6 with external environment condition, on described bonnet 6, offer ventilating opening 11, described ventilating opening 11 is connected with the thermovent 10 of middle plate, described radiator 5 embeds and is fixed in bonnet 6, described lamp holder 7 is spirally connected fixing with bonnet 6, described power supply 4 is electrically connected with aluminium base 3 through wire 12.
