Background technology
At present, worldwide energy shortage has caused the great attention of various countries to power-saving technology.In field of illuminating device, the LED lamp more and more receives publicity with the characteristics of waiting so long in its efficient low-consume, energy-conserving and environment-protective, service life.Existing LED has been widely used on the various bulbs, is the existing light fixture of compatibility, and the structure that LED generally adopts is on existing bulb structure filament to be replaced with LED.But the LED lamp need be close to pcb board (drive circuit board) surface, is equivalent to a flat luminous source, can't shine the space of lamp holder bottom.Because the illumination of LED has this directionality, the illumination direction of LED is generally to be avoided lamp holder, pcb board and the covering of light is selected direction away from lamp holder, and just lamp holder is last, LED throw light on downwards or lamp holder down, the structure of LED up ligthing.
And the omnidirectional substantially illumination of existing incandescent lamp does not have this type of directional problems, so often do not consider the problem of directionality on supporting light fixture, adopts lamp holder following as common desk lamp, and lampshade is at last mounting means.When replacing with the LED bulb, the situation that can not illuminate under the bulb plane can appear causing, problem black under the serious lamp is arranged.So a lot of occasions of existing LED light fixture can't directly be replaced incandescent lamp, and must change supporting fitting structure or continue to use incandescent lamp, limit to the actual promotion and application of LED bulb.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of led light source of alternative incandescent light source is provided, this led light source adopts and realizes ray refraction by a transparent stem stem, reaches even light purpose, makes whole luminous well-balanced, stable.
Realization of the present utility model is finished by following technical scheme:
A kind of led light source of alternative incandescent light source, comprise Transparent lamp shade, the pedestal that links to each other with described Transparent lamp shade and be located at the lamp holder that is used to insert civil power of described base bottom, described pedestal top is equipped with LED lamp and led drive circuit, it is characterized in that: be vertically installed with a transparent stem stem that roughly is column type in the described lampshade, this transparent stem stem is coaxial with described LED lamp, and its top has a depressed part I, and wall is not smooth within the described depressed part I.
Described depressed part I is the cone shape coaxial with described stem stem, and its bottom outer rim overlaps with described stem stem upper end outer rim.
Described depressed part I has wall within the frosted.
The cone angle of described depressed part I is 60 degree-120 degree.
The cone angle of described depressed part I is 90 degree.
Described stem stem bottom offers a depressed part II, is used for coaxial ccontaining described LED lamp.
Described depressed part II is cylindric.
Described stem stem has the moulding that roughly is wavy corresponding to the outer surface of described depressed part II.
The interior place, nearly bottom of described lampshade is provided with an annular pressing plate, and described stem stem bottom is outward extended with flange, and described annular pressing plate is set in outside the described stem stem and with described flange and is fixed.
Described pedestal has good heat-conducting to constitute the radiator of described LED lamp and led drive circuit.
The utility model has the advantages that: by the refraction of stem stem, make bulb not have the directional problems of product in the past, can reach the equal light efficiency of incandescent lamp, can directly have replace incandescent bubble on the light fixture now, and owing to the characteristic reason of led light source, its life-span is 50 times of incandescent bubble, and energy saving reaches the effect of low-carbon environment-friendly more than 10 times.
Description of drawings
Accompanying drawing 1 is the utility model perspective view;
Accompanying drawing 2 is the utility model structural representation.
The specific embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technical staff's of the same trade understanding:
Shown in Fig. 1-2, mark 1-11 is not among the figure: Transparent lamp shade 1, pedestal 2, lamp holder 3, LED lamp 4, led drive circuit 5, transparent stem stem 6, depressed part I7, depressed part II8, astigmatic portion 9, annular pressing plate 10, flange 11.
Referring to Fig. 1-2, the led light source described in the present embodiment comprises Transparent lamp shade 1, the pedestal 2 that links to each other with described Transparent lamp shade 1 and is located at the lamp holder 3 that is used to insert civil power of described pedestal 2 bottoms that described pedestal 2 tops are equipped with LED lamp 4 and led drive circuit 5.This kind structure is the structure of this area LED bulb of commonly seeing, so do not repeat them here.
Different with existing LED bulb is:
One, is folding, the reflection that realizes light, and then reaches the purpose of even light.Present embodiment is vertically installed with a transparent stem stem 6 that roughly is column type in described Transparent lamp shade 1, this transparent stem stem 6 adopts acrylic materials to make, and has the good optical performance.Transparent stem stem 6 bottoms offer a depressed part II8, are used for coaxial ccontaining described LED lamp 4.This depressed part II8 roughly is cylindric, and and transparent stem stem 6 coaxial settings.Transparent stem stem 6 has the moulding that roughly is wavy corresponding to the outer surface of described depressed part II8, is configured for the astigmatic portion 9 of even light.The top of transparent stem stem 6 has a depressed part I7, and described depressed part I7 is the cone shape coaxial with described transparent stem stem 6, and its bottom outer rim overlaps with described transparent stem stem 6 upper end outer rims.The inwall of depressed part I7 is not smooth, has matte surface, to realize the effect of even light.The cone angle scope of the depressed part I7 of this cone shape is that preferred cone angle scope is 45 degree.
