Abstract

The utility model discloses an LED bulb, which is formed by a luminous bulb and an electric connecting base which are combined, and is characterized that the luminous bulb formed by LEDs which are directly packed in a transparent astigmatism body, wherein the LEDs can be one or more than two, the transparent astigmatism body can be a cylindrical body or a sphere, the head end of the cylindrical body is spherical, the electric connecting base has two common structure styles of spiral style or pressing and touch style which are frequently seen, the transparent astigmatism body can enlarge the point-shaped light spots which are sent out by the LEDs into scattered light, which leads the illumination to be more even in the effective lighting scope. The utility model brings enormous change to a common bulb with filaments, which has the advantages of large illuminating brightness and long life span, and saves the utilization factor of energy source, and has significant sense in protecting the environment.

Description

A kind of LED bulb

Technical field

The utility model relates to a kind of bulb, particularly a kind of LED bulb.

Background technology

Existing compact illumination bulb, as the flashlight bulb, its principle of luminosity is luminous by the filament resistance in the bulb, and the luminous efficiency of this kind bulb is low, and power consumption is big, service life is short, irradiation light does not have directionality, when the needs fixed-direction shines, must add reflection shield in addition, increased cost, complex structure.

LED is the abbreviation of English Light Emitting Diode (light emitting diode); its basic structure is an electroluminescent semiconductor devices; place on the leaded shelf; use epoxy sealing then; play the effect of protection internal core, LED has advantages such as luminous efficacy height, life-span length.

If with LED and compact illumination bulb, combine with the structure of bulb as flashlight and to use, then can bring the huge advance made in the use, its brightness is increased, prolong service life greatly, and save electric energy, and structure is simplified.

The utility model content

The purpose of this utility model is low in order to solve existing miniature lamp luminous efficiency, and power consumption is big, complex structure, the problem that service life is short, and provide a kind of LED bulb that can overcome above-mentioned shortcoming, this LED bulb simple structure, brightness is big, long service life, and save electric energy.

The utility model is to be made of luminous bubble and electric connection socket combination, it is characterized in that luminous bubble is directly to be encapsulated in the transparent astigmatism body by LED to constitute, LED wherein can be more than one or two, transparent astigmatism body is a cylindrical body, and the head end of this cylindrical body is spherical; Electric connection socket has two kinds of common common versions, a kind of is spiral, another kind is a touch, the structure of spiral electric connection socket is, the tail end spacer insulator that spiral electrically contacts body is provided with and electrically contacts body, and the positive and negative wiring pin of LED electrically contacts body with spiral respectively and electrically contacts body and is electrically connected and fixes; The structure of touch electric connection socket is, be provided with by the tail end spacer insulator of electric shock contact to electrically contact body, the positive and negative wiring pin of LED respectively with by the electric shock contact with electrically contact body and is electrically connected and fixes.

In addition, transparent astigmatism body can be spheroid or ball-crown body.

The utility model is compared with common filament bulb, has following beneficial effect:

1, the used LED of the utility model, its luminous electron device is directly to be encapsulated in the transparent astigmatism body, installs astigmatism body more in addition additional and not be used on the basis of epoxy sealing;

2, this transparent astigmatism body point shaped laser spot that LED can be sent zooms into scattered light, makes the illumination in the effective lighting scope more even;

When 3, if the utility model need to be used to the directional lighting field, do not need reflection shield.

Though 4, the utility model is that common electric connection socket combines with the simple of LED; but this LED version is different with common LED; and this kind combination has special obvious improvement; brought huge change to common filament bulb; make its luminosity big, long service life, and save electric energy; improved energy utilization rate, environmental protection has been significant.

5, LED is the environmental protection light source, and whole international community is all advocating energetically and promoting, and the utility model has adapted to the development trend and the trend of current environmental protection light source.
