Description

The LED bubble of lighting up

Technical field

The utility model belongs to the technical field of LED illumination, relates in particular to a kind of structure of LED candle bubble.

Background technology

The light source that tradition candle bubble generally uses is a tungsten light source, and not only power consumption is big, and the life-span is short, and because tungsten filament is the fine rule strip, therefore the fidelity of imitation candle flame is relatively poor.

On the other hand, along with continuous advancement in technology, the luminous efficiency of LED substantially exceeds incandescent lamp, even reaches the luminous efficiency of fluorescent lamp.Compare with the traditional electrical light source, the basic nonhazardous of led light source, no electromagnetic pollution, and have many-sided having a few such as volume is little, power consumption is low, light efficiency is high, caloric value is relatively low, long service life, spoilage is low, cost is low.In view of the obvious comprehensive benefit advantage that the relative conventional light source of led light source has, it can be used to substitute tradition candle bubble fully.In the existing commercially available prod, Shang Weijian has LED candle bubble.

The utility model content

The purpose of the utility model is to overcome above-mentioned shortcoming and a kind of LED candle bubble is provided, and it has high efficiency and heat radiation, low energy consumption, the good advantage of candle flame fidelity.

Its objective is such realization: this LED candle bubble comprises circular lamp holder, circular lamp receptacle, lampshade; Circular lamp receptacle is fixedly connected between circular lamp holder and the lampshade, and its main feature is that circular lamp receptacle also is installed with led driver, radiator; One end of radiator is installed with a slice main substrate; Main substrate is arranged in the lampshade inner chamber, has fixedly assigned some substrates on the main substrate, and some LEDs light sources are installed on the every substrate.

Be preferably, main substrate is perpendicular to the central axis of circular lamp holder, and said substrate fixedly oblique cutting is placed on the main substrate.

Be more preferably, the front of a part of substrate obliquely, a part of substrate positive oblique down.The front of so-called substrate is meant that one side that led light source is installed at substrate.

The positive level of each substrate staggers towards dispersion, the front deflection court left side of a part of substrate, and the front deflection court of a part of substrate is right, and be partial to forward in the front of a part of substrate, and be partial to backwards in the front of a part of substrate.

Said lamp socket preferably adopts engineering plastics to make and offer the heat radiation aperture.

It is cylindric that said radiator can be.

Said main substrate is preferably the thermal conductive ceramic main substrate.

Said substrate is preferably the thermal conductive ceramic substrate.

Dimming controlling module preferably is installed in the described led driver.

The utlity model has following advantage and effect:

One, the utility model application of LEDs light source is equipped with scientific and reasonable design as candle bubble light source, has advantages such as high light efficiency, stable, energy-saving and environmental protection.

Two, insulating properties, heat resistance, the heat dispersion of the utility model candle bubble are good, rational in infrastructure ingenious:

A, main substrate and substrate all adopt the highly heat-conductive carbon/ceramic ceramic material, have compared obviously better heat conductivility with conventional aluminium substrate, and insulating properties and heat resistance are also fine, have increased the security reliability of the utility model;

B, lamp socket offer the heat radiation aperture, help steeping the convective exchange of chamber inner air and outside air;

C, said radiator are cylindric; Not only area of dissipation is big; And radiator can be used as the support that main substrate and substrate are installed simultaneously; The inner chamber of radiator can also hold led driver, and the air of lumen of radiator directly is in communication with the outside through the heat radiation aperture, and These characteristics has shown the ingenious property of cylindric heat spreader structures.

Three, compare with traditional tungsten filament candle bubble, the candle bubble of the utility model can better imitate the candle flame, and fidelity is high:

The front of a, a part of substrate obliquely, a part of substrate positive oblique down; The positive level of each substrate staggers towards dispersion; The front deflection of part substrate is towards a left side, and the front of a part of substrate deflection is towards right, and the front deflection of a part of substrate forward; The front deflection of part substrate backwards; The light emission direction of led light source is evenly distributed, and directive is the different directions of front and back up and down, and rising angle is big.

B, because led light source is a dot matrix arranges, the distribution of arranging through the planning dot matrix can simulate the shape of candle flame better, through dimming controlling module respectively to the meticulous control of each LEDs light source, the jump effect that can also imitate out the candle flame better.
