Description

A kind of LED bulb lamp

Technical field

The utility model relates to a kind of lighting, specifically refers to a kind of LED bulb lamp.

Background technology

Along with the progress of society, more energy-conservation LED bulb lamp has progressively replaced traditional incandescent lamp, becomes the principal home and uses lighting.In the prior art the most frequently used LED bulb lamp as shown in Figure 1, it comprises lamp socket 01, housing 02 and lampshade 03; Be provided with power module or power line for the work of driving LED lamp pearl in lamp socket 01 and the housing 02, the described lampshade 03 general collar 06 that passes through links to each other with housing 02, the upper end of housing 02 is equipped with base plate 04, lamp plate 05 is installed on the base plate 04, LED lamp pearl is installed on the lamp plate 05, and lampshade 03 covers on lamp plate 05 top.Because the outer circumference surface of housing 02 is provided with radiating fin 08 array, has certain clearance 07 between the adjacent radiating fin 08, in order to ensure radiating effect, the upper surface of housing 02 is passed in these gaps 07 always from bottom to top along the axis of housing 02.And the base plate 04 that install the upper surface of housing 02 just arranges for the facility that lamp plate 05 is installed, its is general, and what adopt is by the annular opening place that technology is fixed in the upper surface of housing 02 such as compressing, the area of base plate 04 just is slightly larger than the area of lamp plate 05, so that lamp plate can be mounted thereto; And collar 06 covers in the position of the upper surface of housing 02 and also fails to cover described interval, further combined with accompanying drawing 2 and accompanying drawing 3, collar 06 generally is to be spirally connected with housing 02 outer wall as can be seen, lampshade 03 again with collar 06 clamping, and the lower surface of lampshade 03 is unsettled and very narrow, do not prop up gap 07, even arrived to because the thickness of lampshade 03 can not design too thick, also not exclusively cover described gap 07, the space in the lampshade all the time can be by gap 07 and 03 outer being connected of lampshade like this.The LED bulb lamp of said structure in use because gap 07 exists, dust and insect are easy to enter in the lampshade 03, cause the short circuit on the lamp plate 05 easily and make the lampshade inner surface laying dust, have influenced the job stability of LED.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of dust and insect to be not easy to enter the interior LED bulb lamp of lampshade.

For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of LED bulb lamp, it comprises lamp socket, housing, lampshade and lamp plate, the lamp pearl is installed on the lamp plate, the upper end of described lamp socket links to each other with the lower end of housing, described lampshade covers on the housing by collar, and lamp plate is housed in the lampshade; Described housing outer peripheral face is provided with some fins for heat radiation, is provided with the gap between the adjacent fin; It is characterized in that: the upper end of housing is equipped be used to the dust excluding plate that covers the gap between the fin, the inwall of described collar is provided with step surface, the outward flange of dust excluding plate is pressed on the step surface, dust excluding plate is locked at the upper end of housing by tapping screw, lamp plate is fixed on the dust excluding plate, and dust excluding plate is provided with the through wires hole that the lead for lamp plate passes; Described dust excluding plate is aluminium sheet or aluminium alloy plate.

After adopting above structure, the utlity model has following advantage: the upper end of Al-alloy casing is equipped with the dust excluding plate that metal material is made, and the junction of the outer wall of described dust excluding plate and lampshade and collar is close to.Said structure has removed base plate of the prior art, directly do base plate with a dust excluding plate, it can cover the gap between each fin fully, dust and insect can not enter by the gap and save base plate in the lampshade simultaneously, reduced installation procedure, reduced production cost, be exactly that dust excluding plate is made by metal material in addition, when guaranteeing dustproof effect, can not have influence on the heat radiation between lamp plate and the Al-alloy casing fully, therefore, the utility model provides a kind of dust and insect to be not easy to enter the interior LED bulb lamp of lampshade.

As preferably, the lower end of described collar is provided with internal thread, and described housing upper end is provided with step, and the side of step is provided with external screw thread, and collar and housing are spirally connected.The spiro connection structure dismounting is convenient, and is not easy to enter dust in the helicitic texture.

As improvement, described housing is the aluminum or aluminum alloy housing.This material good heat dissipation effect, the intensity height.
