Abstract

The utility model discloses an LED bulb lamp. The LED bulb lamp comprises a lamp cap connected with a power source, a drive plate for driving an LED lamp body, a lamp shade, and a thermal conductor mounted between the lamp cap and the lamp shade, wherein the LED lamp body placed on a base plate is positioned in the lamp shade; the thermal conductor has a hollow shape, and has a cross section with a closed outer edge; the outer edge of the thermal conductor is connected with the inner edge of the thermal conductor through a plurality of radiation ribs; independent radiation channels are formed by two adjacent radiation ribs, the inner edge and the outer edge of the thermal conductor; and radiation windows communicated with the radiation channels are correspondingly arranged in the inlaid position of the lamp cap and the thermal conductor. The outer surface of the thermal conductor can be processed smoothly to prevent from pricking the hand in the prior art or having discomfortable hand feeling, and the like. The LED bulb lamp has the advantages of simple structure and good head dissipation effect.

Description

The LED bulb lamp

Technical field

The utility model relates to light fixture, relates in particular to a kind of LED bulb lamp.

Background technology

The LED bulb lamp has advantages such as power saving, life-span length as the alternative source of light in places such as the modern life, office because of it, used very widely.The structure of existing LED bulb lamp generally includes: with the lamp holder that power supply joins, be used for the drive plate of driving LED lamp body, the LED lampshade is installed in the heat carrier 9 that is used for dispelling the heat between lamp holder and the LED lampshade, as shown in Figure 1.The most direct factor that influences the use of LED bulb lamp is its radiator structure, the effect of heat carrier in the LED bulb lamp is most important, existing heat carrier is generally heat conductivility preferred metal material or alloy material is made, its cross-sectional structure as shown in Figure 2, a plurality of fin are the dispersion shape of heronsbill shape, be provided with bigger radiating surface, with in time, fully conduct, distribute the heat that LED lamp body and drive plate produce, guarantee the long-term operate as normal of LED bulb lamp.

The major defect of the heat carrier of LED bulb lamp shown in Figure 2 is: the cross section is the heat carrier 9 of heronsbill shape diffusion sheet, its outer perimeter is also discontinuous, the cross section of outer rim is discontinuous, when concrete the making, though certain surface treatment, but still may leave burr with the contacted outer rim of human body position, make, install, scratching when safeguarding skin especially easily, therefore need further to be improved.

The utility model content

The purpose of this utility model provides a kind of LED bulb lamp, and the heat carrier that is intended to solve LED bulb lamp in the prior art easily scratches skin, takes up uncomfortable defective.

The LED bulb lamp that the utility model provides, comprise the lamp holder that joins with power supply, the drive plate that is used for the driving LED lamp body, lampshade, be installed in the heat carrier between lamp holder and the lampshade, place the LED lamp body on the substrate to be positioned at lampshade, it is characterized in that: described heat conductor shape is a hollow shape, its cross section outer rim is closed, is connected by a plurality of heat radiation ribs between outer rim and the inner edge.

Further, adjacent two heat radiation ribs and the inside and outside edge in the heat carrier forms independently heat dissipation channel jointly; Described lamp holder correspondingly is provided with a plurality of thermal windows that communicate with heat dissipation channel at the position of splicing with heat carrier.

The LED bulb lamp that the utility model provides, because heat conductor shape is a hollow shape, its cross section outer rim is closed, be connected by a plurality of heat radiation ribs between outer rim and the inner edge, like this, the utility model can be done the outer surface of heat carrier very smooth when making, and needle-holding hand of the prior art can not occur, or taking up phenomenons and simple in structure such as feel is uncomfortable, radiating effect is also fine.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

With reference to Fig. 3, Fig. 4 and Fig. 5, the LED bulb lamp that the utility model provides, comprise the lamp holder 1 that joins with power supply, the drive plate 3 that is used for driving LED lamp body 2, lampshade 4 is installed in the heat carrier 5 between lamp holder and the lampshade, place the LED lamp body 2 on the substrate 6 to be positioned at lampshade, described heat carrier 5 be shaped as hollow shape, its cross section outer rim 51 is closed, is connected by a plurality of heat radiation ribs 53 between outer rim 51 and the inner edge 52; Two sides of the surfaces externally and internally of outer rim 51, heat radiation rib 53 and the outer surface of inner edge 52 are all as radiating surface, in time conduct, distribute heat from LED lamp body and drive plate, to guarantee radiating effect, because cross section outer rim 51 is closed, the outer surface of heat carrier 5 is through simple surface treatment, that promptly can make is smooth, continuous, smooth, its cross section outline can present polygon or circle all can, like this, the phenomenon of burr can appear in its surface hardly, takes up also pleasant.After adopting the heat carrier of this structure, can also be at the random layout of the outer fringe surface of heat carrier, strengthen the aesthetic utility of LED bulb lamp, these advantages all are that the existing heat carrier that is heronsbill shape dispersion shape is not available.

Adjacent two heat radiation ribs and inside and outside edge in the heat carrier 5 form independently heat dissipation channel 54 jointly,, from cross-sectional view, form one by one independently thermal window that is, further guarantee ventilation, radiating effect; Described lamp holder promptly, in the exit of each heat dissipation channel, correspondingly is provided with the thermal window 11 that communicates with the Exit to all routes at the position of splicing with heat carrier.She Ji LED bulb lamp overall structure is more compact like this, also better appearance, and radiating effect also satisfies the instructions for use of LED bulb lamp fully, the prior art of comparing, the utility model both can dispel the heat by window, also can pass through surface radiating, therefore, practical effect is also very good.
