Description

Refrigerator shelf area source

Technical field

The utility model belongs to field of lighting devices, more particularly to the separator face that a kind of refrigerating chamber to refrigerator is illuminated Light source.

Background technology

In order to realize the illumination of refrigerator inside, the top typically inside it is provided with an illuminating lamp, in order that illumination In bright refrigerator all, dividing plate typically uses transparent material, but after article is loaded in refrigerator, these articles can block light Line, and light is only by a little sending, therefore actual illuminating effect is undesirable.

First patent《Refrigerator shelf area source》(U of notification number CN 204085046) although solving the problems, such as illuminating effect, But light guide plate has certain water imbibition, used for a long time in refrigerator wet environment, can dilatancy, illuminating effect change Difference；Safety glass size is small compared with light guide plate, and article, which is placed on light guide plate, has potential safety hazard, is used as dividing plate, load-bearing is still Problem can be produced.

Utility model content

The problem of the utility model exists for above-mentioned prior art, proposes a kind of refrigerator shelf area source.

In order to achieve the above object, the technical solution adopted in the utility model is：

It is provided with a kind of refrigerator shelf area source, including the substrate being made up of safety glass, the substrate spherical glimmering Luminescence unit is installed on light particle, the substrate edges.

The luminescence unit includes being fixed on cooling stand on substrate, and is fixed on cooling stand and can be by base The end face of plate injects the light source of light into substrate.

The cooling stand includes upper plate, lower plate and side plate, and side plate upper and lower ends are connected with upper plate and lower plate respectively, described Substrate is located between upper plate and lower plate, and the light source is arranged on side plate, on the upper plate above the light source and below light source Projection is provided with lower plate.

Preferably, the raised height positioned at upper plate is more than the raised height for being located at lower plate.

Compared with prior art, advantage of the present utility model and good effect are：

1st, the substrate being directly made of safety glass simplifies the structure of area source, and will not inhale as light guide plate Water expands or deformed, and improves the usage amount of safety glass, improves the intensity of area source, enhances weight capacity.

2nd, light is scattered by the fluorescent grain set inside substrate, not only safety glass is replaced leaded light Plate, and light guiding points need not be set in substrate surface, the planarization of substrate surface is improved, and fluorescent grain can reduce steel Change the iron content of glass, the influence that influence iron ion conducts to light, and light can be made to be penetrated from substrate upper and lower surface Go out, improve illumination performance.

3rd, set raised on the cooling stand of luminescence unit, form it into heat dissipation channel, light source luminescent formation can be made Heat quickly sheds, and improves its service life, also mitigates influence of the heat to substrate.Projection above is compared to lower section Projection, space is larger, can accommodate the thermal current of more risings, improves radiating effect.

Brief description of the drawings

Fig. 1 is this refrigerator shelf area source structural representation.

Embodiment

Below, the utility model is specifically described by exemplary embodiment.It should be appreciated, however, that not having In the case of being further discussed below, element, structure and features in an embodiment can also be advantageously incorporated into other implementations In mode.

, it is necessary to explanation, term " interior ", " outer ", " on ", " under ", "front", "rear" etc. in description of the present utility model The orientation or position relationship of instruction are, based on position relationship shown in the drawings, to be for only for ease of description the utility model and simplification Description, rather than indicate or imply that the device or element of meaning must have specific orientation, with specific azimuth configuration and behaviour Make, therefore it is not intended that to limitation of the present utility model.In addition, term " first ", " second ", " the 3rd " are only used for describing mesh , and it is not intended that indicating or implying relative importance.

As shown in figure 1, refrigerator shelf area source, including the substrate 1 being made up of safety glass, it is provided with substrate 1 spherical Fluorescent grain 2, substrate 1 is provided with luminescence unit 3 on edge.

Luminescence unit 3 includes fixed cooling stand 3.1 on substrate 1, and is fixed on cooling stand 3.1 and can The light source 3.2 of light is injected into substrate 1 from the end face of substrate 1.

Cooling stand 3.1 includes upper plate 3.1.1, lower plate 3.1.2 and side plate 3.1.3.

Side plate 3.1.3 upper and lower ends are connected with upper plate 3.1.1 and lower plate 3.1.2 respectively, substrate 1 be located at upper plate 3.1.1 and Between lower plate 3.1.2, light source 3.2 is arranged on side plate 3.1.3, on the upper plate 3.1.1 of the top of the light source 3.2 and lower section of light source 3.2 Lower plate 3.1.2 on be provided with projection 4.

Fluorescent grain 2 in substrate 1 is made up of rare earth, during manufacture substrate 1, is machined directly in safety glass, can drop The content of iron ion in low safety glass.Because iron ion can influence the conduction of light, the reduction of iron ion content is improved The light conduction performance of safety glass, can be played and acted on light guide plate identical directly as substrate 1.

Light source 3.2 is the light-emitting devices such as LED light bar, and the end face that light source 3.2 has substrate 1 injects light, light into substrate 1 Conducted in substrate along the direction parallel with substrate surface.When light runs into the fluorescent grain 2 in substrate 1, due to fluorescence Particle is spherical, fluorescent grain 2 is scattered light, enables light along the direction perpendicular to substrate 1, by the upper table of substrate 1 Face and lower surface are projected, and can improve the illuminating effect in refrigerator to that can be irradiated above and below it.

Projection on upper plate 3.1.1 and lower plate 3.1.2, all forms strip space above and below light source 3.2, makees For heat dissipation channel, the luminous heat energy produced of light source 3.2 is set to be shed by heat dissipation channel, it is to avoid heat makes substrate 1 change colour, and prevents light Its service life is improved by heat ageing in source 3.2.

In order to further improve heat dispersion, the height positioned at upper plate 3.1.1 projection 4 is more than positioned at lower plate 3.1.2's The height of projection 4.

Make the space of the heat dissipation channel of the top of light source 3.2 bigger compared to the heat dissipation channel of lower section, due to thermal current can on Rise, heat can more enter the heat dissipation channel of the top of light source 3.2, the larger heat dissipation channel in space makes the thermal current of convergence more Shed soon, so as to improve heat dispersion.
