Description
Technical field
The utility model relates to a kind of illuminating light source device, relates in particular to a kind of employing filamentray structure framework, can realize 360 ° of omnibearing luminous filament devices.
Background technology
At present, lighting industry is more and more important for the consideration of energy-conserving and environment-protective aspect, and along with emerging and universal use gradually of LED lamp, incandescent lamp is abandoned by people gradually, and LED light fixture has the life-span long.The features such as high, the radiationless and shock resistance of light efficiency, are progressively replacing incandescent lamp.
But because LED light source self is luminous, there is directive property, even if the light sending is after the diffusion of diffusion shell, compared with conventional incandescent lamp source that can omnirange luminous intensity distribution, the luminous intensity distribution angle of existing LED lamp still seems very narrow, luminous intensity distribution angle is generally all below 120 °, light can not reach the back of lamp, can form shadow.
At present, although there are some LED lamps can accomplish that wide-angle light distributes, use the optical elements such as a large amount of reflectors, lens, installed larger diffusing globe cell-shell.But using this kind of mode one is that LED light efficiency is reduced, the 2nd, make LED lamp need to greatly reduce heat-dissipating space when maintaining alternative form, thereby while making LED work, temperature can be in any more, LED power cannot be done greatly.Meanwhile, existing big-angle LED lamp all needs to use diffusion shell to carry out astigmatism, and illuminating effect and traditional incandescent lamp also have larger gap.
In recent years, the progress with semiconductor fabrication process that emerges in large numbers along with new material, there is the luminous LED filament of Liao Neng omnidirectional, can be luminous within the scope of 360 degree, but this kind of filament is because luminous quantity is large, therefore produce amount of heat, need heat radiation in time, the radiator of existing LED lamp is generally made by metal or pottery, and weight is heavier, easily degeneration or fracture, have larger potential safety hazard.And the LED support of the luminous LED filament of this type of omnidirectional is owing to being solid construction entirely, the 360 degree scopes that need to realize are when luminous, at least need the reverse installation of two LED wafers could realize the luminous of 360 degree, the effect that this has just greatly increased manufacturing cost and has affected heat radiation.
Summary of the invention
The purpose of this utility model is the existing defect of technology that solves omnibearing luminous filament device in prior art, a kind of 360 ° of all-round light modulation silk devices are provided, these 360 ° all-round light modulation silk devices pass through six luminous LED chip die bonds on the aperture of the hollow out of fine strip shape support, LED chip is across aperture as a bridge, the face all around of LED chip and end face all can be luminous, the light that send bottom surface sees through aperture ejaculation from appear at the back side of fine strip shape support, reaches omnibearing luminous object.
The utility model solves the technical scheme that its technical problem adopts: a kind of 360 ° of all-round light modulation silk devices, comprise fine strip shape support, in one end of fine strip shape support, be provided with electrode separation insulating part, the aperture of a plurality of hollow outs is set along straight line on fine strip shape support; On fine strip shape support, also die bond has and is positioned at all luminous LED chips of aperture top six, and each LED chip is connected in series successively with gold thread and separates insulating part with gold thread connecting electrode.This fine strip shape support utilizes stamping technology to stamp out aperture, and LED chip die bond on aperture, six of LED chips all can be luminous, the light-emitting area of LED chip bottom surface is irradiated to cradle back by aperture light, reaches 360 ° of omnibearing luminous objects.
Further, the fine strip shape metallic support that described fine strip shape support is metal material.Adopt fine strip shape metallic support simpler and convenient for aspects such as LED chip installation welding, its fastness is also very good.This fine strip shape metallic support is used as miniaturization, and similar toothpick shape can be realized the bottom printing opacity of LED chip.
Or described fine strip shape support is the fine strip shape glass supporter of clear glass material.Adopt glass material to make fine strip shape glass supporter, can be applied in lamp bar, light pipe and bulb lamp needs in the good field of light transmittance.
Further, in end face and the bottom surface of fine strip shape support, be respectively provided with a LED chip, two LED chips are sandwiched between corresponding aperture.This frame mode is to be equipped with a LED chip at the top of aperture and bottom, can make the luminous luminosity uniformity of each position angle.
Further, described aperture is I-shaped shape.The aperture of I-shaped shape meets 360 ° of omnibearing luminous needs of LED chip.
In sum, the advantage that 360 ° of all-round light modulation silk devices of the present utility model have is as follows: these 360 ° all-round light modulation silk devices pass through six luminous LED chip die bonds on the aperture of the hollow out of fine strip shape support, LED chip is across aperture as a bridge, the face all around of LED chip and end face all can be luminous, the light that send bottom surface sees through aperture ejaculation from appear at the back side of fine strip shape support, reaches omnibearing luminous object.
