Abstract
The utility model relates to the technical field of LED lamps, in particular to an LED bulb lamp. The LED bulb lamp comprises a spiral socket, a heat dissipation casing, a glass bulb and a constant current power supply module, the top of the spiral socket of the LED bulb lamp is connected with the heat dissipation casing, the constant current power supply module is arranged in the heat dissipation casing, the top of the heat dissipation casing is connected with the glass bulb, an LED lamp panel is mounted at a connecting position of the heat dissipation casing and the glass bulb, the heat dissipation casing is in a circular ring shape, uniformly distributed sectorial through holes are formed in the upper surface of the heat dissipation casing in the circular ring shape, sides of the sectorial through holes, which are close to an inner ring of the circular ring shape heat dissipation casing, are provided with a plurality of first upright heat dissipation plates, and sides of the sectorial through holes, which are close to an outer ring of the circular ring shape heat dissipation casing, are alternately provided with a plurality of second upright heat dissipation plates at intervals. Compared with traditional LED bulb lamps, the LED bulb lamp has the advantages that the structure is simple, the sectorial through holes and the upright heat dissipation plates are reasonably distributed in and on the heat dissipation casing, heat dissipation effects of the LED bulb lamp are improved, and the service life of the LED bulb lamp is prolonged.
Description
[technical field]
The utility model relates to LED lamp technical field, specifically a kind of LED bulb lamp.
[background technology]
Along with the LED light fixture is more and more universal, and the LED bulb lamp is widely used in various occasions because it has long, light efficiency high of energy-conservation, life-span, while working due to the LED bulb lamp, only having the small part electric energy conversion is luminous energy, most of electric energy is all because the bad heat energy that is converted into of heat radiation cause energy utilization rate low, and radiating effect missionary society affects the service life of power module, reduced the reliability of LED bulb lamp, so the heat dissipation problem of LED bulb lamp is the emphasis of research at present.
Domestic patent publication No. CN102798106 discloses a kind of LED bulb lamp heat abstractor and heat dissipating method, its composition comprises: pedestal, connect the aluminium base LED lamp plate with the LED lamp above described pedestal, connect heat-dissipating casing below described pedestal, described heat-dissipating casing connects lamp holder, described pedestal clamping lampshade, and described lamp holder connects driving power, this LED bulb lamp heat abstractor and heat dissipating method complex structure, and also there is improved space in radiating effect.
[utility model content]
In order to overcome existing LED bulb lamp above shortcomings and defect, the utility model provides the LED bulb lamp of a kind of good heat dissipation effect, long service life.
To achieve these goals, invent a kind of LED bulb lamp and comprise screwed socket (1), heat-dissipating casing (2), glass ball bulb (3), constant-current supply module (4), it is characterized in that: the screwed socket of described LED bulb lamp (1) top connects heat-dissipating casing (2), heat-dissipating casing (2) inside is provided with constant-current supply module (4), heat-dissipating casing (2) top connects glass ball bulb (3), heat-dissipating casing (2) is provided with the LED lamp panel with glass ball bulb (3) junction, described heat-dissipating casing (2) is circular, circular heat-dissipating casing upper surface is provided with equally distributed fan-shaped pylone, fan-shaped pylone is provided with the some first upright heat sink near circular heat-dissipating casing inner ring one side, fan-shaped pylone replaces the spaced apart some second upright heat sink near circular heat-dissipating casing outer ring one top-cross.
The described second upright heat sink bottom section shape matches with the fan-shaped pylone outer.
The utility model is compared with traditional LED ball bulb lamp structure, simple in structure, is uniformly distributed fan-shaped pylone the proportional spacing upright heat sink that distributes on heat-dissipating casing, has increased the radiating effect of LED bulb lamp, extends the service life of LED bulb lamp.
