Abstract

A LED light fixture with radiator in increasing decoration is disclosed herein comprising a LED chip and a radiator, wherein the radiator comprises two liquid storage tanks whereon one liquid storage tank is in thermo-contact with the LED chip, the two liquid storage tanks being internally provided in encapsulation with a cooling liquid, the two liquid storage tanks being connected to each other through a cooling liquid convection pipe, the cooling liquid convection pipe being entirely or partially made of light penetration materials, the light fixture being provided with a luminous element for irradiation to the cooling liquid inside the cooling liquid convection pipe. As the utility model employs the cooling liquid to conduct heat radiation on the LED chip, the radiation conducted inside the cooling liquid convection pipe by light emitted from the luminous element makes the cooling liquid convection pipe look like a lighting pipe where flowing of the cooling liquid is visible from outside, which makes the light fixture eye-catching and increases decoration for the LED light fixture.

Description

Utilize radiator to promote ornamental LED light fixture

Technical field

The utility model relates to the LED light fixture.

Background technology

With the LED light fixture of light-emitting diode chip for backlight unit (hereinafter to be referred as " led chip "), all has a radiator that helps the led chip heat radiation as light-emitting component.In the prior art, the radiator of most of LED light fixtures does not possess ornamental, radiator need be hidden, and it is certain ornamental that the moulding of the radiator heat-dissipation fin of minority LED light fixture reaches, but can not play noticeable effect, ornamental very weak.

The utility model content

The purpose of this utility model provides a kind of radiator that utilizes and promotes ornamental LED light fixture.

LED light fixture described in the utility model comprises led chip and radiator, described radiator comprises two fluid reservoirs, one of them fluid reservoir and led chip thermo-contact, be packaged with cooling fluid in two fluid reservoirs, be connected with the cooling fluid convection tube between two fluid reservoirs, all or part of cooling fluid convection tube adopts light transmissive material to make, and light fixture is provided with the light-emitting component of irradiation cooling fluid convection tube, and described light-emitting component shines the cooling fluid in the cooling fluid convection tube.

The utility model utilizes the convection current of cooling fluid to help the led chip heat radiation, the scattering process of light in the cooling fluid convection tube that utilizes light-emitting component to send simultaneously, make cooling fluid convection tube such as same luminous tube, and from can see that in appearance cooling fluid flows in luminous tube, very noticeable, noticeable, promoted the ornamental of LED light fixture.

The specific embodiment

Embodiment 1

Referring to Fig. 1, Fig. 2, the LED light fixture comprises two fluid reservoirs 1,2, one of them fluid reservoir 1 and led chip 3 thermo-contacts.The mode of thermo-contact comprises direct contact and the mediate contact that relies on heat carrier heat conduction.Be packaged with cooling fluid in two fluid reservoirs 1,2.Cooling fluid can be an existing known cooling fluid such as water, oil emulsion, ethylene glycol, propane diols.Be connected with cooling fluid convection tube 4 between two fluid reservoirs.Cooling fluid convection tube 4 is columned solid tubes made from light transmissive materials such as glass or acrylics, offers passage 5 in the solid tubes.Cooling fluid in two fluid reservoirs plays the effect that helps led chip 3 heat radiations via passage 5 convective flow.Light fixture is provided with light-emitting component 6.Light-emitting component 6 shines the cooling fluid in the passage 5 over against the end of passage 5, makes cooling fluid convection tube 4 as same luminous tube, and can see that from the light fixture outside cooling fluid flows in luminous tube.Light-emitting component 6 can adopt the low-power LED chip, and can be the led chip of color changeable, or the combination of the led chip of multiple color.

Embodiment 2

Referring to Fig. 3, Fig. 4, the characteristics that present embodiment is different from embodiment 1 be the cooling fluid convection tube by many separately independently hollow pipe 7 constitute.In order to protect the cooling fluid convection tube, also be provided with transparent protective shield 8, cooling fluid convection tube 7 is enclosed in the protective cover 8.Other structures of present embodiment can be with reference to embodiment 1.

Embodiment 3

Referring to Fig. 5, the characteristics that present embodiment is different from embodiment 1 are that the cooling fluid convection tube is made of the

hollow pipe

9,10 of two inside and outside sockets, cooling fluid flows between the tube wall of outer tube 9 and interior pipe 10, and light transmissive materials such as outer tube and interior effective glass or acrylic are made.Be inserted with leaded light post 11 in interior pipe, light transmissive materials such as leaded light post available fiber or acrylic are made.Be provided with small-power light-emitting component 12 in the end of leaded light post, pipe 10 in the light that this light-emitting component sends enters into via the guiding of leaded light post 11, and manage under the scattering process of leaded light post, shining in 10 and outer tube 9 between cooling fluid on.Referring to Fig. 6, between the tube wall of outer tube 9 and interior pipe 10, demarcation strip 13 can be set, the cavity between outer tube and the interior pipe is divided into many passages.Other structures of present embodiment can be with reference to embodiment 1.

Embodiment 4

Referring to Fig. 7, Fig. 8, the characteristics that present embodiment is different from embodiment 3 are that the cross section of outer tube 14 is a quadrangle, and interior pipe 15 has many, all are inserted with leaded light post 16 in every interior pipe.Other structures of present embodiment can be with reference to embodiment 3.

If the led chip of LED light fixture is more, a plurality of fluid reservoirs can be set, connect the cooling fluid convection tube between per two fluid reservoirs.Many cooling fluid convection tubes are arranged, and can be that all or part of cooling fluid convection tube adopts light transmissive material to make.
