Abstract

An LED bulb lamp comprises a lamp cap, a heat radiation connecting component, a reflection cup and a lamp screen that are sequentially mounted. An LED driver for driving the operation of an LED light source is positioned inside the heat radiation connecting component, the LED light source is positioned at the lower part of the heat radiation connection component, the heat radiation connection component is hollow, and a lower heat radiation hole and an upper heat radiation hole that help air enter the interior of the heat radiation connecting component from the lower part and flow out from the upper part of the heat radiation connecting component are respectively formed at the lower part and the upper part of the heat radiation connecting component. The LED bulb lamp has reasonable structure and is convenient for assembly, and through the lower heat radiation hole and the upper heat radiation hole that are respectively formed at the lower part and the upper part of the heat radiation connecting component to help air enter the interior of the heat radiation connecting component from the lower part and flow out from the upper part of the heat radiation connecting component, the heat generated by the lamp is rapidly radiated to the outside of the lamp in an air natural convection manner, so as to ensure operating temperature of the lamp, ensure more stable operation of the lamp, prolong the service life of the lamp and facilitate safety regulation certification of the lamp.

Description

A kind of LED bulb lamp

Technical field

The utility model relates to a kind of LED light fixture, specifically a kind of improvement of LED bulb lamp structure.

Background technology

Along with the development of society and the raising of people's living standard, the LED bulb lamp will certainly substitute conventional incandescent bulb and power saving fluorescent lamps because of advantages such as it are of fine quality, durable, energy-conservation, light is soft, being applied in the daily life more and more widely.But the LED bulb lamp produces a large amount of heats in the course of the work, and heat such as untimely the evacuation will influence light fixture service behaviour and service life.

In the prior art, people are the radiator structure by improving the LED bulb lamp or establish air-vent on one's body at lamp and solve the bad problem of light fixture heat radiation mostly, but most of light fixture radiating effect still makes consumers in general dissatisfied, the poor reliability of light fixture, job insecurity, service life is short.

The utility model content

The technical problems to be solved in the utility model provides a kind of LED bulb lamp of good heat dissipation effect.

For solving the problems of the technologies described above, the utility model by the following technical solutions:

A kind of LED bulb lamp, comprise lamp holder, heat radiation coupling assembling and reflector and the lampshade installed successively, the led driver of driving LED light source works is arranged in the heat radiation coupling assembling, led light source is positioned at heat radiation coupling assembling bottom, described heat radiation coupling assembling is a hollow, heat radiation coupling assembling bottom and top offer respectively be beneficial to air enter from the bottom heat radiation coupling assembling following louvre inner and that flow out from heat radiation coupling assembling top and on louvre.

As improvement to such scheme, above-mentioned heat radiation coupling assembling comprises a tubular plastic cement connector and the radiating fin that is placed in plastic cement connector periphery together, plastic cement connector upper end is affixed with lamp holder, led light source directly is affixed on the radiating fin lower surface, and following louvre runs through radiating fin lower sides and radiating fin lower surface.

As further improvement of these options, above-mentioned led driver vertically stands in the heat radiation coupling assembling by the base plate that is fixed in the radiating fin lower surface, and following louvre runs through base plate.

Further, above-mentioned last louvre is opened in plastic cement connector upper surface shoulder.

The beneficial effects of the utility model:

The utility model is rational in infrastructure, easy to assembly, heat radiation coupling assembling bottom and top offer respectively be beneficial to air enter from the bottom radiating subassembly following louvre inner and that flow out from radiating subassembly top and on louvre, the heat that makes light fixture produce is dispersed into the light fixture outside rapidly under the natural convection air mode, guaranteed the operating temperature of light fixture, make the light fixture more stable work, the light fixture longer service life also more helps the authentication of product safety.

The specific embodiment

For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing:

As accompanying drawing 1-5, a kind of LED bulb lamp, comprise lamp holder 1, heat radiation coupling assembling 2 and reflector 3 and lampshade 4, led light source 7 and the led driver 8 installed successively, heat radiation coupling assembling 2 comprises a tubular plastic cement connector 21 and a radiating fin 22, led light source 7 is positioned at heat radiation coupling assembling 2 bottoms and directly is affixed on radiating fin 22 lower surfaces, led driver 8 vertically stands in the heat radiation coupling assembling 2 by the base plate 23 that is fixed in radiating fin 22 lower surfaces, and led driver 8 is used for 7 work of driving LED light source.

Wherein, above-mentioned heat radiation coupling assembling 2 is a hollow, and plastic cement connector 21 upper ends and lamp holder 1 are affixed, radiating fin 22 is placed in plastic cement connector 21 peripheries admittedly, radiating fin 21 is swirl shape and arranges that radiating fin 21 has increased the area of dissipation of light fixture, improves the light fixture radiating effect.Heat radiation coupling assembling 2 bottoms and top offer respectively down louvre 91 and on louvre 92, following louvre 91 runs through radiating fin 22 lower sides and radiating fin 22 lower surfaces, following louvre 91 also runs through base plate 23; Last louvre 92 is opened in plastic cement connector 21 upper surface shoulders, following louvre 91 and go up louvre 92 and help air enter heat radiation coupling assembling 2 from the bottom inner and flow out from heat radiation coupling assembling 2 tops.

In the present embodiment, the following louvre 91 of heat radiation coupling assembling 2 and 92 designs of last louvre are in order not influence the light fixture outward appearance, thereby will descend louvre 91 and last louvre 92 to hide design safely, following louvre 91 and the last louvre 92 formation stack effect that communicates, promptly under the natural convection air mode room air from following louvre 91 flow through base plate 23 from flow out the louvre 92, air is in light fixture in the process of circulation, a large amount of heats that 7 work of light fixture led light source produce are taken out of, thereby make heat be dispersed into the light fixture outside rapidly, guaranteed the operating temperature of light fixture, make the light fixture more stable work, the light fixture longer service life also more helps the authentication of product safety.

The foregoing description is the preferred version that the utility model is realized; and it is non-limiting exhaustive; the utility model can also have other variations under same idea; need to prove; under the prerequisite that does not break away from the present utility model design, any conspicuous replacement is all within the utility model protection domain.
