Abstract
The utility model relates to a lighting device and a refrigerator using the same, which belongs to the field of home appliances and aims to solve the technical problem of achieving a good area light source effect while the illumination brightness of light-emitting diodes (LED) is not influenced. An LED lighting device comprises a lamp box of which one end is provided with an opening, LED lamp bulbs mounted in the lamp box, and a light guide plate sealing the opening of the lamp box, wherein the light guide plate is a nanometer light guide plate of which the inner part is evenly and dispersedly provided with nanometer particles. The refrigerator using the lighting device comprises a refrigerating bin, wherein the lamp box of the lighting device is embedded in a side wall of the refrigerating bin; and the plastic light guide plate extends out of the side wall of the refrigerating bin. Another refrigerator using the lighting device comprises the refrigerating bin, wherein the lamp box of the lighting device is mounted on the side wall of the refrigerating bin.
Description
Technical field:
The utility model relates to a kind of lighting device, also relates to a kind of refrigerator that uses this lighting device, belongs to field of household appliances.
Background technology:
LED is the abbreviation of English light emitting diode (light emitting diode); its basic structure is an electroluminescent semi-conducting material, places on the leaded shelf, uses epoxy sealing then all around; play the effect of protection internal core, so the anti-seismic performance of LED is good.Simultaneously compare the 80%-90% that to economize on electricity with traditional incandescent lamp; And the life-span can reach 8-10 ten thousand hours, was more than 10 times of incandescent lamp, and advantage such as LED has energy-conserving and environment-protective, luminous volume is little, reliability is high and the life-span is long.Along with the develop rapidly of semiconductor technology, the trend of various traditional lighting light source products has appearred tentatively substituting in LED lighting engineering at present.The interior lighting of household electrical appliance such as refrigerator also is a key areas in domestic lighting market, how the various advantages with the LED lighting engineering apply to this field, thereby when improving brightness, save inner space and power consumption, become an important problem.
Because the light that light emitting diode sends has axial property, what can illuminate is limited in scope, if expect the area source that scope is big, just LGP must be set outside light emitting diode.Traditional LGP generally prints reflective site or carves netted ruling on transparent acrylic sheet material, utilize the reflecting layer of LGP surface printing or the ruling of engraving to make the even diffusion of light; Perhaps directly will there be the lampshade of frosted finish effect to be installed on the LED lamp, but this type of structural design relates to a large amount of optical knowledges, with the brightness of LED, arrange, lampshade is all multifactor relevant apart from LED lamp distance etc., the big cost height of difficulty in addition will sacrificing luminance when realizing better area source effect.
The utility model content:
Technical problem to be solved in the utility model realizes area source effect preferably exactly when not sacrificing LED illumination brightness.
In order to solve above-mentioned technical problem, the utility model adopts following technical scheme:
A kind of LED lighting device comprises the lamp box of an end opening and is installed in the interior LED bulb of lamp box, and the LGP that seals up lamp box opening, and described LGP is the inner nanometer LGP that evenly disperses to be provided with nano particle.
A kind of refrigerator that uses above-mentioned lighting device comprises the refrigeration storehouse, and the lamp box of above-mentioned lighting device embeds the sidewall in refrigeration storehouse, and the nanometer LGP stretches out the sidewall in refrigeration storehouse.
The another kind of refrigerator that uses above-mentioned lighting device comprises the refrigeration storehouse, and the lamp box of above-mentioned lighting device is installed on the sidewall in refrigeration storehouse.
The beneficial effects of the utility model are, because be the inner nanometer LGP that evenly disperses to be provided with nano particle in the LGP, need not the surface of plastic cement LGP is printed or carve, just can reach the good light effect of sparing; And, can when saving complicated structural design, shorten the distance between LGP and the LED lamp because after adopting this nanometer LGP the distance between LGP and the LED lamp is not required, further reduce the loss of brightness.This LED lighting device is installed on the sidewall in refrigerator cold-storage storehouse, can well solves the lighting problem in the refrigerator.And adopt the design that this LED lighting device is embedded refrigeration storehouse sidewall, can when not influencing illuminating effect, further save the space in refrigeration storehouse.
Description of drawings:
Fig. 1 is the schematic diagram of this LED lighting device;
Fig. 2 is to use the schematic diagram of the refrigerator of this LED lighting device;
Fig. 3 is to use the schematic diagram of the another kind of refrigerator of this LED lighting device.
Description of reference numerals: 1-lamp box, the 2-LED bulb, 3-nanometer LGP, 4-refrigerates storehouse, 5-sidewall.
The specific embodiment:
Embodiment 1:
As shown in Figure 1; this LED lighting device; the lamp box 1 and the LED bulb 2 that is installed in interior relative opening one side of lamp box that comprise one one end opening; and the LGP 3 that seals up lamp box openend; for reaching even light effect; this LGP should have certain thickness; it in the LGP the inner nanometer LGP that the nano particle of dispersion evenly is set; in the prior art; in LGP, increase the method for nano particle and have the nano particle kind of even light effect all to belong to common practise; and therefore the protection domain that does not belong to utility model patent repeats no more.
Embodiment 2:
As shown in Figure 2, the sidewall 5 in refrigerator cold-storage storehouse 4 is embedded in the LED lighting device of installing among the embodiment 1, and wherein above-mentioned lamp box 1 embeds in the sidewall in refrigeration storehouse, and nanometer LGP 3 stretches out outside the sidewall in refrigeration storehouse.
Embodiment 3:
As shown in Figure 3, the difference of present embodiment and embodiment 2 is that lamp box 1 is installed on the sidewall 5 in refrigerator cold-storage storehouse 4.
In conjunction with the accompanying drawings the utility model preferred implementation has been done detailed description above, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skills possessed, can also under the prerequisite that does not break away from the utility model aim, make various variations.For example: above-mentioned LED lighting device also can use in other household electrical appliances such as ice box or micro-wave oven.
