Abstract
The utility model relates to an LED bulb with a ceramic isolation plate. The LED bulb comprises a lamp holder, a connecting piece, a heat dissipation shell body, an LED light-emitting component and a lampshade. The lampshade is arranged on the upper portion of the heat dissipation shell body, and the connecting piece connected in a threaded mode is arranged on the lower portion of the heat dissipation shell body. The lamp holder is connected to the lower portion of the connecting piece, an electronic driving assembly for driving the LED light-emitting component is arranged in a cavity formed in the middle of the connecting piece, the electronic driving assembly is connected with the LED light-emitting component through a power source wire, the LED light-emitting component is fixedly arranged on the plane of the upper portion of the heat dissipation shell body, and a layer of ceramic isolation plate is arranged between the heat dissipation shell body and the LED light-emitting component. Due to the fact that one layer of ceramic isolation plate is arranged between the LED light-emitting component and the heat dissipation shell body, a good isolation and insulation effects can be achieved, and the safety and the electric shock prevention character of the product are guaranteed. The heat produced when the LED light-emitting component works normally can be well transmitted to a heat dissipation device, and a good heat dissipation effect is achieved.
Description
Technical field:
The utility model relates to the field of lighting, relates in particular to a kind of LED bulb with ceramic division board.
Background technology:
Along with the superseded continuous propelling of incandescent lamp, directly the LED bulb of replace incandescent has also welcome great development opportunity, the LED light-emitting component is welded on the substrate, the LED light-emitting component can produce a large amount of heats when work, therefore, substrate is directly installed on the radiating element, so that the heat that the LED light-emitting component produces outwards distributes by radiating element.In addition, in the prior art, also have housing made with metal material, and radiating element is connected with housing, with housing also as radiating element, in order to reach better radiating effect.But there is such problem in this existing LED bulb, and the substrate in its LED light-emitting component is to be made by copper foil layer and aluminium base, and a layer insulating is arranged between copper foil layer and aluminium base, and in order to improve radiating effect, this insulating barrier is generally done very thinly.When abnormal high temperature appears in the LED lamp or have high voltage to scurry into, this layer insulating is easy to breakdown and damages, and the input voltage of built-in electric drive assembly reaches 100-240V, therefore, in case abnormal, high voltage can be scurried in the LED light-emitting component, cause aluminium base strip high-tension electricity, and conduct to radiating element, so housing, cause the hidden danger of electric shock.
The utility model content:
The technical problems to be solved in the utility model is the above-mentioned deficiency for prior art, provides a kind of high voltage that can prevent to scurry into, and reaches the LED bulb with ceramic division board of great heat radiation effect.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
LED bulb with ceramic division board, comprise lamp holder, connector, radiating shell, LED light-emitting component and lampshade, wherein, top at radiating shell is provided with lampshade, the bottom of radiating shell is provided with the connector that is threaded connection, the bottom of connector is connected with lamp holder, in the cavity that the middle part of connector forms, be provided with the electric drive assembly for the driving LED light-emitting component, the electric drive assembly is connected with the LED light-emitting component by power lead, the LED light-emitting component fixedly is located on the upper plane of radiating shell, is provided with one deck pottery division board in the centre of radiating shell and LED light-emitting component.
The beneficial effects of the utility model are: the LED bulb with ceramic division board of the present utility model is provided with one deck pottery division board between LED light-emitting component and radiating shell, and ceramic material has fabulous insulating properties, therefore, even the LED light-emitting component is scurried into because accident causes high voltage, the pottery division board can play good isolation and insulating effect, prevent that high voltage from further scurrying on the radiating shell, thereby guarantee security and the protection against electric shock characteristic of product.Simultaneously, ceramic material has preferably heat conductivility, and therefore, the heat that produces in the time of can preferably the LED light-emitting component being worked conducts to radiating element, keeps good thermolysis.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Referring to shown in Figure 1, a kind of LED bulb with ceramic division board of the present utility model, comprise lamp holder 1, connector 2, radiating shell 4, LED light-emitting component 6 and lampshade 7, wherein, be provided with lampshade 7 on the top of radiating shell 4, the bottom of radiating shell 4 is provided with the connector 2 that is threaded connection, the bottom of connector 2 is connected with lamp holder 1, in the cavity that the middle part of connector 2 forms, be provided with the electric drive assembly 3 for driving LED light-emitting component 6, electric drive assembly 3 is connected with LED light-emitting component 6 by power lead, LED light-emitting component 6 fixedly is located on the upper plane of radiating shell 4, be provided with one deck pottery division board 5 in the centre of radiating shell 4 and LED light-emitting component 6, to play the effect of isolation electric current and conduction heat.
