Abstract
The utility model relates to an LED (light-emitting diode) bulb lamp which comprises a lampshade (9), a copper screw base (1), a shell (4), a power driving component (3) and a self-tapping screw (8), wherein the copper screw base (1) is mounted at the lower end of a power bushing (2) in a threaded connection manner; the power driving component (3) is arranged inside the power bushing (2); an aluminum-based radiating plate (5) is arranged at the upper end of the shell (4); the power bushing (2) penetrates through the bottom part of the shell (4) to connect with the lower end of the aluminum-based radiating plate (5); a circuit board (6) is arranged on an upper surface of the aluminum-based radiating plate (5); the self-tapping screw (8) penetrates through the circuit board (6) and the aluminum-based radiating plate (5) and is fixed with the power bushing (2); and the lampshade (9) is connected and fixed with the aluminum-based radiating plate (5) by threads arranged on the lower end thereof and matched with the aluminum-based radiating plate (5). The LED bulb lamp provided by the utility model is simple in structure and obvious in heat dissipation effect, internal parts are protected and the service life is prolonged.
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) because high, life-span of its power consumption shortly gradually forbidden production by national governments; substitute products are electronic energy-saving lamps thereupon; although electronic energy-saving lamp has improved energy-saving effect; but owing to having 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 are not in the situation that need to change former conventional lamp pedestal and circuit just can use LED illuminating product of new generation.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 threaded connection the lower end that is installed in the 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 equipped with circuit board, 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 screw thread and the aluminium base heat sink that its lower end and aluminium base heat sink match.
The upper surface of described circuit board is welded with several light emitting diodes.
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; its shell adopts the fine aluminium shell; can heat luminous in the bulb be imported in the air with the heat radiation form of radiation 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 the fine aluminium shell, and radiating effect is obvious; can protect the bulb lamp internal part, prolong its service life.
