Description

The LED bulb

Technical field

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

Background technology

LED has advantages such as volume is little, caloric value is low, power consumption is low, the life-span is long as a kind of emerging light emitting semiconductor device, and therefore at present having occurred some on the market is the light fixture of light source with LED.Existing LED light fixture mostly is to form at the peripheral directly sheathed lampshade of LED, influenced the light extraction efficiency of LED, and its radiating effect is not good, has influenced the service life of light fixture greatly.

The utility model content

The purpose of the utility model is to overcome the defective that prior art exists, and a kind of high light efficiency, LED bulb that thermal diffusivity is good are provided.

The technical scheme that realizes the utility model purpose is: a kind of LED bulb has lamp holder, lamp socket, radiator and led light source assembly; Said lamp holder is fixedly connected with lamp socket; Said lamp socket is connected with fastener of radiator; Has radiator on the said radiator; Said led light source assembly is fixedly installed on the radiator; Have heat dissipation channel on the central shaft of said radiator.

Technique scheme also has power supply driver; Said power supply driver is fixedly installed on the lamp socket, and places in the heat radiation chamber of radiator, and power supply driver electrically connects with lamp holder and led light source assembly respectively through lead.

The said radiator of technique scheme has two installed surfaces at least, has at least one group of led light source assembly on each installed surface.

Technique scheme also has diffuser; Said diffuser is arranged on the installed surface of radiator, covers the led light source assembly.

Technique scheme also has reflection shield; Said reflection shield is fixedly installed in the installed surface of radiator.

The said radiator of technique scheme has four symmetrically arranged installed surfaces, has one group or two groups of led light source assemblies on each installed surface.

The said radiator of the technique scheme outside has the ventilation slot that is parallel to the bulb axis.

The utlity model has positive effect:

(1) the utility model has heat dissipation channel on the central shaft of radiator; Play thermolysis, improved the service life of bulb.

(2) power supply driver of the utility model is fixedly installed on the lamp socket, and places in the heat radiation chamber of radiator, and power supply driver electrically connects with lamp holder and led light source assembly respectively through lead; Power supply driver can convert the alternating voltage of outside input into the DC voltage of LED demand, accomplishes the power supply to LED.

(3) radiator of the utility model has two installed surfaces at least, has at least one group of led light source assembly on each installed surface; The realization full angle is luminous.

(4) the utlity model has reflection shield; Reflection shield is fixedly installed on the installed surface of radiator; When LED is luminous, can direct projection light directly be refracted to the diffuser outside, also can reflection ray be reflexed to the diffuser outside once more, reduce the light loss consumption, improve illumination brightness.

(5) radiator of the utility model outside has the ventilation slot that is parallel to the bulb axis; Can improve radiating effect.
