Abstract

The utility model relates to an LED bulb lamp radiator which comprises a bottom cover, a heat conducting plate and a lampshade. The lower portion of the heat conducting plate and the bottom cover are fixed through bolts or buckles, a plurality of wave holes are arranged on the inner side wall of the bottom cover, a circle of air scattering windows communicated with the wave holes are arranged at a position, close to the bottom end, on the outer wall of the bottom cover, a plurality of heat radiating holes are circumferentially arranged on the inner side wall of the heat conducting plate, an LED aluminum substrate is fixed at the top of the heat conducting plate through heat conducting glue and screws, the lampshade is covered outside the heat conducting plate, and the lampshade and the heat conducting plate are fixed by a thread. The heat conducting plate can lead heat on an LED lamp piece on the LED aluminum substrate out of the lampshade, so that heat radiating space is increased; the holes between the bottom cover and the heat conducting plate can enable heat in the lamp to be led out of the LED lamp through air convection, so that heat radiating effect is improved; and mutual transmission of heat generated by the LED lamp piece and heat driven by an LED is avoided, and the heat of each part is led and discharged by the chimney principle to form circulation and convection, so that the service life of the whole lamp is guaranteed.

Description

A kind of LED bulb lamp heat radiator

Technical field

The utility model relates to a kind of thermal convection cooling type LED bulb lamp heat radiator.

Background technology

The LED lamp of traditional type because lamp sheet caloric value is large, can only dispel the heat with the upper cover that aluminium section bar heronsbill radiator is made, but processing cost and consumptive material is larger, and the LED lamp cost of making of plastics is low, but radiating effect is bad, and the light decay of LED lamp is fast, and the life-span is short.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of LED bulb lamp heat radiator simple in structure, easy to use, can not only successfully go out the thermal conductance of LED lamp sheet, the heat that produces in lamp is dispelled the heat through cross-ventilation, and material deterioration inside is little, and good heat dissipation effect is safe and reliable.

LED bulb lamp heat radiator of the present utility model, comprise bottom, heat-conducting plate and lampshade, fix by bolt or buckle between the bottom of described heat-conducting plate and bottom, the madial wall of bottom is provided with some waves holes, be provided with by positon of near bottom the loose transom window that a circle communicates with the wave hole on the outer wall of bottom, be circle distribution on the madial wall of heat-conducting plate some louvres are arranged, the top of heat-conducting plate is fixed with the LED aluminium base by heat-conducting glue and screw, the outside of heat-conducting plate is covered with lampshade, fixes by screw thread between lampshade and heat-conducting plate.

LED bulb lamp heat radiator of the present utility model, the inside of bottom is provided with locating dowel and buckle.

Compared with prior art the beneficial effects of the utility model are: the heat-conducting plate of LED bulb lamp heat radiator of the present utility model can export to the heat on the LED lamp sheet on the LED aluminium base outside of lampshade, increase heat-dissipating space, hole between bottom and heat-conducting plate can make the heat in lamp derive the outside of LED lamp through cross-ventilation in addition, improve radiating effect, avoid LED lamp sheet because the heat that produces heat and LED driving transmits mutually, utilize chimney principle formation circulation and convection current that the heat guide of each several part is gone out, guarantee the life-span of whole lamp.

The specific embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.

As shown in Figure 1, a kind of LED bulb lamp heat radiator, comprise bottom 1, heat-conducting plate 2 and lampshade 3, fix by bolt or buckle between the bottom of described heat-conducting plate 2 and bottom 1, the madial wall of bottom 1 is provided with some waves hole 4, be provided with by positon of near bottom the loose transom window that a circle communicates with wave hole 4 on the outer wall of bottom 1, be circle distribution on the madial wall of heat-conducting plate 2 some louvres 5 are arranged, the top of heat-conducting plate 2 is fixed with LED aluminium base 6 by heat-conducting glue and screw, the outside of heat-conducting plate 2 is covered with lampshade 3, fixes by screw thread between lampshade 3 and heat-conducting plate 2.

LED bulb lamp heat radiator of the present utility model, the inside of bottom 1 are provided with locating dowel 7 and buckle 8.

LED bulb lamp heat radiator of the present utility model is when concrete the use, and the heat radiation on the LED aluminium base is through heat-conducting glue and heat-conducting plate, thermal conductance to be gone out, and dispels the heat by louvre and the wave hole formation cross-ventilation of bottom.Heat in lampshade is by forming the cross-ventilation heat radiation between the gap of junction on the louvre on heat-conducting plate and lampshade and heat-conducting plate.The utility model can convection current due to the ambient air of heater element, and exports to the outside of LED lamp, so radiating efficiency is high, the LED lamp behaviour is stable, reduces aluminium, avoids the problem of plastics poor heat conductivity, and is safe and reliable.

The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
