Description

A kind of LED bulb lamp

Technical field

The utility model relates to a kind of lighting apparatus, especially a kind of indoor LED lamp.

Background technology

Existing bulb lamp adopts traditional tungsten filament to prepare, and it is a thermal light source, not only lack service life, and waste of energy is serious, contaminated environment.Occurred the LED bulb lamp in recent years, and adopted solid state LED as illuminating source, but exist more problem, the popularization that has directly influenced the LED bulb lamp mainly contains following four problems with universal:

1,, cause in the use caloric value big, and the rising of temperature will directly influence the LED life-span, so the heat radiation of LED bulb lamp has been proposed higher requirement because the defective of led chip self is more;

2, LED belongs to the plane small area light source, and the light-emitting area that how to increase the ball bubble also is a difficult point;

3, white light LEDs adopts blue chip to excite the YAG powder technology more, but owing to lack red spectrum, causes the colour rendering of white light LEDs bulb lamp relatively poor, is lower than 80, and is difficult to obtain the white light LEDs of low colour temperature;

4, the LED driving power be installed in the radiator or metallic lamp holder in, most producers adopt directly installs or mode that the insulation film parcel is installed, owing to bulb is used in the power supply environment of 220V or 110V more, so exist bigger potential safety hazard.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned existence, provides that a kind of colour rendering is higher than 90, luminous efficiency is higher than 90lm/W, good heat dissipation effect, the luminous LED bulb lamp in safe, big zone.

The purpose of this utility model is finished by following technical solution, a kind of LED bulb lamp, and it includes:

One led light source parts comprise the led light source that is made of white light LEDs and red-light LED;

One power supply unit includes driving power;

One lamp body parts include lamp holder, lamp socket, insulating part, radiator, lid and lampshade;

Described driving power is arranged in the insulating part, and this insulating part is fixed in the groove at radiator middle part, and there is wire hole the insulating part top and the bottom, divides two-way respectively to white light LEDs and red-light LED power supply, and electric current is adjustable.

The ratio of described white light LEDs and red-light LED was at least 3: 1, and the ratio of described white light LEDs and red-light LED can be 4: 1.

Described led light source adopts COM (Chip on Metal) area source encapsulation technology, FPC is attached on the substrate, every chips adopts the independent grooves encapsulation, by the gold thread welding, reduces in the bonding wire process impact to chip between chip and the FPC.

Described groove is a metal groove, and the red-light LED groove is positioned at the middle part of white light LEDs groove, the spacing≤2mm between groove, and described groove top can be provided with lens.

Described substrate is that copper base material or aluminium base are made.

Cooperate by spiral between described lamp holder, lamp socket and the radiator.

Described lampshade is connected by bayonet socket or spiral with radiator.

Described lampshade is contracted by nothing and becomes the PC material or implosion guard is made frosting.

The utility model adopts technique scheme, and every chips adopts the independent grooves encapsulation, makes the chip overall heat reduce, and has increased the chip cooling area, improves the service life of chip; Every chips directly welds by gold thread with FPC, reduces in the bonding wire process impact to chip, raising chip stability; Adopt white light LEDs and red-light LED mixed light, improve whole color developing effect of light source and luminous efficiency; Driving power is fixed in the groove of radiator, isolates by insulating part and radiator, and the driving power thermal diffusivity is good, security performance is high, increases product service life.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done detailed introduction: shown in Fig. 1-5: a kind of LED bulb lamp, it includes:

One led light source parts comprise the led light source 7 that is made of white light LEDs 9 and red-light LED 10;

One power supply unit includes driving power 4;

One lamp body parts include lamp holder 1, lamp socket 2, insulating part 3, radiator 5, lid 6 and lampshade 8;

Described driving power 4 is fixed in the insulating part 3, and this insulating part 3 is fixed in the groove at radiator 5 middle parts, and there is wire hole insulating part 3 top and the bottom, divide two-way respectively to white light LED9 and red-light LED 10 power supplies, and electric current is adjustable.

The ratio of described white light LEDs 9 and red-light LED 10 was at least 3: 1, and the ratio of described white light LEDs 9 and red-light LED 10 can be 4: 1.
