Description
Technical field
The utility model relates to field of illuminating lamps, particularly a kind of LED bulb lamp.
Background technology
Under the overall situation of global resources anxiety; conventional incandescent (tengsten lamp) is because its power consumption is high, the life-span weak point is forbidden producing by national governments gradually; substitute products are electronic energy-saving lamps thereupon; although electronic energy-saving lamp has improved energy-saving effect; but owing to used the heavy metal element of many contaminated environment, run counter to again the main trend of environmental protection.Become gradually the only choosing of novel green illumination along with the high speed development LED illumination of LED technology, LED is far superior to the traditional lighting product on the aspect of principle of luminosity, energy-saving and environmental protection, LED illumination manufacturer must develop the LED illuminating product that meets existing interface and people's use habit, so that people just can use LED illuminating product of new generation not needing to change in the situation of former conventional lamp pedestal and circuit.So the LED bulb lamp just arises at the historic moment, replaced gradually incandescent lamp.Although and the LED bulb lamp is energy-conservation, also can produce a lot of heats in long-time use, too high heat can reduce its service life, so the radiator structure of LED bulb lamp self is very important.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of LED bulb lamp, and simple in structure, easily manufactured, radiating effect is obvious, and the protection internal part prolongs its service life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED bulb lamp is provided, comprise lampshade, the copper screw socket, shell, power drives assembly and self-tapping screw, described copper screw socket is mounted on the lower end of power supply sleeve, described power drives assembly is installed in the inside of power supply sleeve, the upper end of described shell is equipped with aluminium base heat sink, described power supply sleeve passes with the lower end of aluminium base heat sink from the bottom of shell and links to each other, the upper surface of described aluminium base heat sink is installed with circuit board by several cheese head screws, described several self-tapping screws pass circuit board and aluminium base heat sink and fix with the power supply sleeve, and described lampshade is connected and fixed by buckle and aluminium base heat sink.
The upper surface of described circuit board is welded with several light emitting diodes.
Evenly have fairshaped air groove around the outside of described shell.
Described lampshade is made by translucent PC engineering material.
Beneficial effect
The utility model relates to a kind of LED bulb lamp; simple in structure; have air groove around its shell; can heat luminous in the bulb be imported in the air with the heat radiation form of convection current and go; and driven unit and luminous lamp tube are isolated fully, and the heat that driven unit produces also imports in the air by air groove, and radiating effect is obvious; can protect the bulb lamp internal part, prolong its service life.
