Description

A kind of LED bulb

Technical field

The utility model relates to lighting field, relates in particular to a kind of LED bulb.

Background technology

Traditional bulb is an incandescent light bulb, and its light is not bright, not energy-conservation.The fluorescent lamp bulb after incandescent light bulb, occurred, though it is energy-conservation, light is also brighter, since a large amount of fluorescent material that uses, therefore not enough environmental protection, and the power that uses is all bigger, and service life is generally not long.Occurred more energy-conservation at present and LED lamp source environmental protection, produced the LED bulb thereupon, existing LED bulb common configuration is complicated; Mainly comprise three parts: lamp holder, neck and luminous sphere, lamp holder all are standard components, and neck generally has plastics and two kinds of materials of metal; Neck generally is lighttight; Be mainly used in to connect and dispel the heat and perhaps place driver, luminous sphere generally has plastics and two kinds of materials of metal, is used for printing opacity; And generally needing the extra heat abstractor of setting up, its profile is compared with the ordinary incandescent lamp bulb with internal structure has bigger difference.

Yet single LED illuminator luminance shortage, light fixture just can play illuminating effect under the situation of a plurality of LED illuminators.Existing light fixture generally all is to increase the luminous efficiency of LED illuminator through adding high-amperage; Its structure is a plurality of LED illuminators of welding on the pcb board of control circuit; This LED lamp current amount is also bigger, and caloric value is also bigger, has shortened the service life of LED light fixture greatly.

The utility model content

Be the problem that overcomes the not enough of prior art and exist, it is a kind of rational in infrastructure that the utility model provides, and luminous efficiency is high, and heat radiation is even, and radiating efficiency is high, the LED bulb of long service life.

The utility model is realized through following technical scheme: a kind of LED bulb; The Lamp cup that comprises lamp holder, lampshade, connection lamp holder and lampshade; The control circuit assembly is set in the said lamp holder, semiconductor light-emitting-diode is set in the lampshade, this semiconductor light-emitting-diode is connected with the control circuit electrical component; Be fixed with a substrate in the said lampshade, said semiconductor light-emitting-diode is arranged on this substrate; The opposite side of this substrate also is provided with a radiator.

Be provided with a tubular pedestal in the said lampshade, said substrate is fixed on this pedestal, and said radiator is located in this pedestal.Said radiator is to be finned radiator and the central shaft of column to hollow.

Said lampshade is olive-type or spherical, adopts glass or plastic material.

Said substrate, pedestal adopt aluminum material or copper material or ceramic material.

The utility model and prior art compare, and good looking appearance is rational in infrastructure; Luminous efficiency is high, and manufacturing cost is not high, owing to be provided with radiator; Dispel the heat simultaneously through substrate and radiator, improve radiating efficiency, make that the LED bulb heat radiation is more even; The heat that can in time semiconductor light-emitting-diode be produced leaves, and has effectively prolonged the service life of semiconductor light-emitting-diode, thereby can prolong the life-span of LED bulb.

Description of drawings

Fig. 1 is the cross-sectional view of prior art;

Fig. 2 is the cross-sectional view of the utility model.

Among the figure: 1-lamp holder, 2-lampshade, 3-Lamp cup, 31-shell, 32-joint, 4-control circuit assembly, 5-semiconductor light-emitting-diode, 7-substrate, 8-radiator, 81-standard shaft, 82-fin, 9-pedestal.

The specific embodiment

For the ease of those skilled in the art's understanding, the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.Should be pointed out that specific embodiment described herein only is used to explain the utility model, and be not used in qualification the utility model.

Shown in accompanying drawing 1; A kind of LED bulb comprises lamp holder 1, lampshade 2, connects the Lamp cup 3 of lamp holder 1 and lampshade 2, in the said lamp holder 1 control circuit assembly 4 is set; Semiconductor light-emitting-diode 5 is set in the lampshade 2; This semiconductor light-emitting-diode 5 is electrically connected with control circuit assembly 4, is fixed with a substrate 7 in the said lampshade 2, and said semiconductor light-emitting-diode 5 is arranged on this substrate 7; The opposite side of this substrate 7 also is provided with a radiator 8.The quantity of this semiconductor light-emitting-diode 5 is several, is the main light-emitting component of the utility model, has the high characteristics of luminous efficiency.This circuit board 4 comprises at least one circuit board.

Be provided with a tubular pedestal 9 in the said lampshade 2, these pedestal 9 one end openings, the other end is provided with the installation position, and said substrate 7 is fixed on the installation position of this

pedestal

9, and 8 in said radiator is installed in this pedestal 9.The heat that produces during the work of LED lamp can be transferred to radiator 8 through substrate 7 immediately.

Said radiator 8 for the finned radiator that is column and central shaft to hollow; Adopt aluminum extruded formula radiator; Comprise standard shaft 81 and some fins 82, said standard shaft 81 is the cylindrical body of a hollow, and said fin 82 is parallel to the central shaft of said standard shaft 81; And all the outer wall from said standard shaft 81 radially extends; Make entire radiator 8 be the cylindrical shape that outer wall is arranged deep trouth, heat is to all the winds dispersed rapidly from said standard shaft 81, reaches the technique effect that can obtain bigger area of dissipation under the small size situation.
