Abstract
The utility model relates to an LED bulb lamp, which includes a lamp cap, a heat sink and a bulb. The bottom of the heat sink is fixed on the lamp cap, an LED light source in the bulb is mounted on the heat sink and is electrically connected with the lamp cap, the bulb is fixed on the upper end surface of the heat sink, and heat sink fins on the surface of the heat sink are spiral. The LED bulb lamp adopts the spiral heat sink fin structure, enlarges the heat dissipation area of the heat sink fins, and can improve the heat dissipation efficiency of the bulb.
Description
Technical field
The utility model relates to lighting technical field, relates in particular to a kind of LED bulb lamp.
Background technology
The LED bulb lamp is the novel energy-conserving light fixture that substitutes the conventional incandescent bulb.The conventional incandescent power consumption is high, the life-span is short; under the overall situation of global resources anxiety; gradually, forbidden producing by national governments; substitute products are electronic energy-saving lamps thereupon; though electronic energy-saving lamp has energy-saving advantages; but, run counter to the main trend of environmental protection again owing to used the heavy metal element of many contaminated environment.Only choosing along with the illumination of the high speed development LED of LED technology illumination becoming gradually novel green, LED is far superior to the traditional lighting product on the aspect of principle of luminosity, energy-saving and environmental protection, people arise at the historic moment with regard to spendable LED bulb lamp not needing to change under the situation of former conventional lamp pedestal and circuit.
And the bulb lamp radiator structure mostly is the vertical heat radiation rib that is distributed in spreader surface in the market, and radiating effect is not good.
The utility model content
The utility model provides a kind of LED bulb lamp at the above-mentioned defective of prior art, to improve the radiating efficiency of bulb.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of LED bulb lamp, comprise lamp holder, radiator, ball bubble, the radiator bottom is fixed on the lamp holder, and the led light source in the ball bubble is installed on the radiator and with lamp holder and is electrically connected, the ball bubble is fixed on the radiator upper surface, and the radiating fin of described spreader surface is a spirality.
Described radiator is a hemispherical dome structure.
As can be seen from the above technical solutions, the utility model adopts the spirality radiation fin structure, has increased the area of dissipation of radiating fin, has improved the radiating efficiency of bulb.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is described in further detail.
Shown in accompanying drawing, the utility model LED bulb lamp, comprise lamp holder 1, radiator 2, ball bubble 3, radiator 2 bottoms are fixed on the lamp holder 1, led light source in the ball bubble is installed on the radiator and with lamp holder and is electrically connected, ball bubble 3 is fixed on the radiator upper surface, and the radiating fin on described radiator 2 surfaces is a spirality.
As preferred implementation of the present utility model, described radiator 2 is a hemispherical dome structure.
Above-mentioned specific embodiment is purpose, feature and the effect that is used for describing in detail the utility model, for the personage who is familiar with this type of skill, according to the above description, may do part change and modification to this specific embodiment, its essence does not detach the spiritual category person of the utility model, all should be included in the claim of this case suitable first Chen Ming.
