Detailed description of the invention
Describe embodiment of the present utility model in detail below with reference to drawings and Examples, to the utility model, how application technology means solve technical problem whereby, and the implementation procedure reaching technique effect can fully understand and implement according to this.
Embodiment 1
Attached Fig. 1 and 2 discloses a kind of LEDbulb lamp implemented according to the utility model, it specifically comprises: lampshade 10, substrate 20, lamp holder 30 and LED light source 30, wherein LED light source is installed on the base plate 20, substrate 20 one end is positioned at lampshade 10, the other end is positioned at lamp holder 30, and lampshade 10 is combined by buckle with lamp holder 30.
Concrete, the top of lampshade 10 and position, middle and lower part are provided with air vent and catch 11,12, realize forming cross-ventilation in bulb lamp inside, and wherein catch is connected with hole but does not affect cross-ventilation, can be one-sided combination or fence connection, enter in lampshade to prevent dust.In the present embodiment, the heat radiation that LED light source produces, under the prerequisite of LED light source bright dipping thus can be discharged outside bulb lamp by cross-ventilation as much as possible near LED light source at not shadow by the position of the air vent 12 of middle and lower part fast fast.Please refer to accompanying drawing 2, air vent 12 is positioned at the oblique below of LED light source 40, and it does not affect the bright dipping of LED light source 40 substantially, can the heat radiation that LED light source 40 produces be discharged fast outside bulb lamp fast again simultaneously.
Substrate 20 is for installing LED light source 40 and dispelling the heat, inside is provided with circuit, and surface is provided with LED source light, and in the direct bare metal of the area part not installing LED light source, carry out heat exchange for accelerating with air, wherein exposed metal is generally away from LED light source.Preferably, LED light source installation region and the neighbouring surface of substrate 20 also can be coated with insulation reflective material layer, while guarantee LED light source electrically safety, also can improve light extraction efficiency and the light mixed effect of LED light source.In the present embodiment, substrate 20 forms (certainly by two laminated structures intersections, substrate 20 is not limited to laminated structure, also can be bar shape structure), setting is set in lampshade 10, its material is the good materials of heat conductivility such as aluminium base, FR4 insulation board, copper base, and wherein when using FR4 insulation board, its surface is coated with metallic radiating layer.LED light source 40 to be arranged in the middle part of substrate 20 in 21 sidewall surfaces, top 22 and bottom 23 are non-LED light source installation region, its surface directly bare metal, the heat of substrate 20 can upwards be derived by metal that wherein substrate 20 top 22 is directly exposed fast, and discharged by the air vent 11 at lampshade 10 top, the directly exposed metal in substrate 20 bottom 23 can carry out heat exchange with air fast, thus is derived by the heat of substrate 20, and is discharged by the air vent 12 of lampshade middle and lower part.In the middle part of substrate 20,21 surfaces are coated with insulation reflective material layer.For increasing the contact area of the exposed metal of substrate and air, setting up fin 50 on the top 22 of substrate, to increase the heat exchange with air, thus increasing radiating effect.
