Description
Technical field
Technical field of LED illumination is the utility model is related to, specifically a kind of LEDbulb lamp using modeling alclad technology.
Background technology
LED luminescent screens for illumination can produce a large amount of heat energy when work, commonly used in the trade to solve heat dissipation problem
Means one be air velocity forced heat radiation is improved using fan, two be to utilize metal fin increase area of dissipation active heat removal；
Because fan inevitably results from noise and consumes electric energy, with having many defects, existing LED in LED illumination device
Bulb lamp mostly uses the radiating mode of metal fin, and still, this outer surface is exposed, inner surface directly contacts luminescent screen
Not only complex manufacturing, production cost are high for metal fin, the danger got an electric shock also be present.
The content of the invention
The purpose of this utility model is to provide a kind of LED ball rational in infrastructure, good heat dissipation effect using modeling alclad technology
Lamp is steeped, its simple production process, manufacturing cost are low, thoroughly prevent Danger Electric shock risk.
To achieve the above object, the utility model uses following technical scheme：
A kind of LEDbulb lamp using modeling alclad technology described in the utility model includes columned housing, is connected to shell
The taper changeover portion of body upper end, the interface for being connected to taper changeover portion upper end, LED is installed in the inner chamber of the housing and lighted
Plate, the LED luminescent screens are fixedly connected on the bottom of heat conduction cup, and the heat conduction cup is by cylindric wall of cup and is arranged on wall of cup
The goblet that the bottom of a cup of bottom is formed, the heat conduction cup interference fit are sleeved in housing, connected in the lower end of housing by buckle
It is connected to the lampshade of spherical shell shape.
The housing, taper changeover portion and lampshade are made by engineering plastics, and the heat conduction cup is made up of aluminium alloy.
The fin being axially distributed is provided with the outer surface of housing.
After adopting the above technical scheme, the LED lamp bulb structure is reasonable, good heat dissipation effect, while have production technology simple
Singly, the characteristics of manufacturing cost is low, and thoroughly prevent Danger Electric shock risk, it is safe and reliable.
Specifically, the LEDbulb lamp compares traditional heat-dissipating mode, has following features：
First, heat-conducting area is big.Inside is using punching press aluminium cup and PBT engineering plastics combinations, as LED luminescent screens
Radiator., can be effective by heat caused by LED light emitting sources by increasing the contact area of LED luminescent screens and punching press aluminium cup
It is delivered on aluminium cup radiator.Second, heat dissipation path is short.The shell that internal punching press aluminium cup is done with PBT engineering plastics, passes through interference
Coordinate technique to be in close contact, substantially reduce LED luminescent screens to radiator, then the distance distributed to air.LED luminescent screens are normal
Heat transfer path greatly shortens during work, is advantageous to the transmission of heat energy.3rd, heat loss through radiation effect is good.With reference to aluminium cup heat conduction
Good, plastics heat loss through radiation is good, and how the not many consideration light fixture of heat loss through radiation is put.Bulb lamp is set to coordinate original lampshade, will not
LED light source light decay is influenceed because of convection effects difference.4th, heatsink weight is light, and materials are few.It is actual by taking bulb lamp 45W as an example
The use of 1060 type aluminium alloy weight is 114g, PBT engineering plastics 168g.And traditional 50W heatsink weights are typically in 800-
1000g, the dosage of metal aluminium is greatly reduced, reduce radiator cost.5th, good insulation preformance, the test of light fixture safety
Easily pass through.Due to using plastic wraps punching aluminum component mode, lamp outer casing is engineering plastics, and whole lamp insulating properties are greatly carried
Rise.Using the technology, rated voltage 220V light fixture, the pressure-resistant numerical value of insulation of whole lamp reaches 5000V, is marked considerably beyond country
It is accurate.And non-isolated power supply can be adapted to, power supply cost reduces by more than 50% when can compare isolation.
