Abstract

The invention relates to an LED lighting device and belongs to the technical field of lighting facilities. The LED lighting device comprises a set of LED light-emitting devices which are in series connection with one another and/or are arrayed on a substrate to form lighting units after series connection, and the substrate is a transparent ceramic substrate. The transparent ceramic substrate features in good heat conduction and radiation cooling performance and is pervious to light, so that the problem about heat dissipation is solved; the LED lighting device can give out light on both the front side and the reverse side, so that lighting brightness is remarkably improved while the lighting range is remarkably enlarged.

Description

A kind of LED lighting device

Technical field

The present invention relates to a kind of lighting device, especially a kind of LED lighting device, belongs to lighting installation technical field.

Background technology

LED has advantages of energy-conserving and environment-protective as lighting installation, therefore obtains applying comparatively widely.According to the applicant understood, the LED lighting device of relatively high power all needs to arrange the backboard heat radiation structure with expansion area of dissipations such as radiating ribs at present.This type of radiator structure not only makes LED illuminator structure become complicated, and volume expands, and because radiator structure is light tight, thereby limited giving full play to of LED illumination functions.

Summary of the invention

The object of the invention is to: the shortcoming existing for above-mentioned prior art, proposes a kind of simple in structure, good heat dissipation effect, can comparatively give full play to the LED lighting device of LED photechic effect.

In order to reach above object, LED lighting device basic technical scheme of the present invention is: comprise one group of LED luminescent device, described LED luminescent device mutually connect and/or parallel connection after be arranged on substrate and form lighting unit, described substrate is light-transmittance ceramics substrate.Described light-transmittance ceramics can be one of sintered alumina, magnesia, beryllium oxide, yittrium oxide, yittrium oxide-zirconium dioxide, GaAs, zinc sulphide, zinc selenide, magnesium fluoride, calcirm-fluoride.

Not only there is good heat conduction because light-transmittance ceramics substrate has, heat loss through radiation performance, and there is the feature of printing opacity, after therefore adopting, in having solved heat dissipation problem, also make lighting device of the present invention positive and negative all luminous, thereby significantly improved brightness of illumination and illumination zone.

When enforcement, at least two described lighting units horizontal or vertically-arranged side by side, forms three-dimensional illumination structure, thereby can realize stereo luminous effect, due to the not shading each other of each lighting unit, therefore can give full play to LED photechic effect.

The present invention further improves, described lighting unit has at least upper and lower two-layer, the larger lighting unit projection nucleus of containment area is around the less lighting unit of adjacent containment area, and realizes mechanical connection and the electrical connection of adjacent layer by the metal column of the less lighting unit circumferential distribution of containment area simultaneously.

The present invention makes each lighting unit reasonable combination together, makes full use of space heat elimination, and luminous being independent of each other each other, thereby makes LED illuminator structure compactness of the present invention, stable performance, long service life.

The present invention further improves, distribute and form from top to bottom by circle or annular lighting unit, the uniform outward flange with perforation of lighting unit periphery that adjacent containment area is less, corresponding with the inward flange with perforation of Zhou Junbu in the larger lighting unit of adjacent containment area, support and be connected by metal column and securing member respectively each other.

The present invention further improves, and the LED luminescent device of described lighting unit is by parallel again after extending to the printed circuit of outward flange perforation place and mutually connecting.

The present invention further improves again, after described lighting device encapsulation, is placed in the glass bulb on lamp socket.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the present invention is further illustrated.

The specific embodiment

Embodiment mono-

The LED lighting device of the present embodiment as depicted in figs. 1 and 2, by lighting unit 2-1,2-2,2-3, the 2-4 of four layers of circle or annular form from top to bottom, the projection nucleus of lower one deck lighting unit that wherein containment area is larger is around the less lighting unit of adjacent last layer containment area, except the superiors, all the other lighting units are annular.Uniform three outward flanges with perforation of lighting unit periphery that adjacent containment area is less, corresponding with three inward flanges with perforation of Zhou Junbu in the larger lighting unit of adjacent containment area, support and be connected by metal column 2-5 and securing member respectively each other.

The lighting unit of the superiors as shown in Figure 3, comprises one group of LED luminescent device 2-7, and these LED luminescent devices are first connected into some rows as required, more parallel with one another by extending to the printed circuit 2-8 at outward flange perforation 2-9 place, is arranged on light-transmittance ceramics substrate 2-6.Like this, in the time adopting metallic copper post 2-5 by adjacent bed lighting unit mechanical connection, also realized required electrical connection.The lighting unit 2-2 of lower floor, 2-3,2-4 are except LED luminescent device is distributed in annular region, and other formation is not difficult to know by inference according to aforementioned.

When use, after the lighting device 2 of the present embodiment can encapsulate, as shown in Figure 4, be placed in the glass bulb 1 of lamp socket 3, thus the lighting of formation and existing lamp holder adaptation.

Test shows, the present embodiment compared with prior art, has following remarkable advantage:

1) ceramic substrate has light transmission, and lighting device positive and negative are luminous (luminosity of reverse side is about positive luminous 10%) all, can improve light efficiency more than 10%;

2) basic self the thermal conductivity of pottery is good, and lighting unit, not in same aspect, can fully dispel the heat by space delamination;

3) metallic copper post had both been realized mechanical connection, had realized again required electrical connection.

In addition to the implementation, the present invention can also have other embodiments.For example, two or more multi-disc lighting unit by how much rules horizontal or vertically-arranged side by side, form three-dimensional illumination structure; And for example, the shape of levels substrate is not limited to circle, annular, can be also arbitrary polygon, polygon ring, or other geometry; For another example, the magnitude setting of metal column and setting position can change as required; Etc..All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
