Abstract
The invention discloses a total-reflection honeycomb backlight LED illuminating lamp of a refrigerator and the refrigerator using the illuminating lamp. The illuminating lamp comprises a plurality of surface mounted LED lamps arranged on the front surface of a lamp panel, light emitting surfaces of the LED lamps cling to one side of a light guide plate, reflective paper is pasted on the other three sides of the light guide plate, a honeycomb engraved groove is engraved on one surface of the light guide plate, a reflective plate is arranged on the side of the light guide plate with the engraved groove, the lamp panel, the light guide plate and a reflective plate are connected onto a refrigerator clamp, and a closed cavity is formed between the light guide plate and the reflective plate. The illuminating lamp has the advantages of safety, low power consumption, low heating value, large light emitting surfaces, and soft and uniform light, has no extremely dense area, and can bring fresh and bright use experience for users in both daytime and nighttime.
Description
Technical field:
The present invention relates to a kind of refrigerator total reflection honeycomb fashion LED illuminating lamp backlight, and the refrigerator that is equipped with this illuminating lamp.
Background technology:
At present, refrigerator case intraoral illumination adopts incandescent lamp or point-like LED lamp mostly, cooperates lampshade that spot light is dispersed.But because glow color problem and heating and spatial constraints; Can't ideally convert spot light into area source; Vision class and refrigerator configured in one piece are also inharmonious; Several moneys are installed in the scheme at low-transmittance floodlight plate rear owing to take up room excessively with LED on the market, and practicality is relatively poor, and high-end refrigerator is needed the illuminated by surface light source system that a low-power consumption, low heating, high brightness, low spatial take badly and matched with it.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of refrigerator total reflection honeycomb fashion LED illuminating lamp backlight, this installs simplicity of design, and processing technology is ripe, and simple installation is reliable.
The present invention further provides a kind of refrigerator that above-mentioned lighting device is housed, and this refrigerator is owing to adopt this ultra-thin LED lamp backlight, can outer air channel and the volume of occupying volume, thus rationally utilize the air channel and reduce the purpose that the refrigerator dischargeable capacity takies.
Technical solution problem of the present invention adopts following technical scheme:
Refrigerator total reflection honeycomb fashion LED illuminating lamp backlight; The lamp plate front is provided with several paster LED lamps, and the light outgoing plane of said LED lamp is close to a side of LGP, posts reflective sheeting in addition three sides of said LGP; The one side of said LGP is carved with honeycomb fashion engraving groove; Side at the LGP that is provided with the engraving groove is provided with reflector, and said lamp plate, LGP and reflector are connected on the refrigerator fastener, form sealed hollow between said LGP and the reflector.
The back side of said lamp plate is connected with fin, and said fin is connected on the said refrigerator fastener.
A kind of refrigerator comprises a chamber at least, is connected with above-mentioned total reflection honeycomb fashion LED illuminating lamp backlight through the refrigerator fastener on the one side in said chamber or a plurality of.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, adopt direct current 12V input, rated current is 100mA only, and the temperature rise of fin is 35K only, and other positions do not produce autonomous heat.The engraving groove of acrylic LGP and upward setting thereof converts the spot light of LED lamp into area source through total reflection.
2, refrigerator total reflection honeycomb fashion of the present invention LED illuminating lamp backlight, according to total reflection principle, all light of injecting outlet of bounce back air once more only have honeycomb engraving groove, and the light source utilization rate is high.With on equidistant, light intensity reaches as high as the twice of like product brightness, and light-emitting area is big, brightness is even, stingless eye spot or make us dizzy light beam.
3, the present invention's similar lighting device volume after installing takies reduction and reaches 60% at most.
Description of drawings:
Fig. 1 is the structural representation of refrigerator total reflection honeycomb fashion of the present invention LED lighting device backlight.
Fig. 2 is the center line cross-sectional plane sketch map of Fig. 1.
Fig. 3 analyses and observe schematic perspective view for center line of the present invention.
Fig. 4 is the A portion enlarged drawing of Fig. 2, light reflection in the reflection LGP, total reflection and refraction principle, and wherein arrow is represented reflection, the refraction route of light.
Label among the figure: 1 reflector, 2 fin, 3 fasteners, 4 LGPs, 5LED lamp, 6 lamp plates, 7 reflective sheetings, 8 engraving grooves.
Below pass through the specific embodiment, and combine accompanying drawing that the present invention is described further.
The specific embodiment:
Embodiment: referring to Fig. 1-4, the refrigerator total reflection honeycomb fashion LED illuminating lamp backlight of present embodiment, lamp plate 6 fronts are provided with several paster LED lamps 5; The light outgoing plane of LED lamp 5 is close to a side of LGP 4, posts reflective sheeting 7 in addition three sides of LGP 4, and the one side of LGP 4 is carved with honeycomb fashion engraving groove 8; Side at the LGP that is provided with the engraving groove is provided with reflector 1; Lamp plate 6, LGP 4 and reflector 1 are connected on the refrigerator fastener 3, are installed in through refrigerator fastener 3 on the inner face of refrigerator chamber, and wherein LGP 4 is towards the refrigerator inner room; Reflector forms sealed hollow towards the refrigerator inwall between LGP 4 and the reflector 1.In specifically being provided with, the back side of lamp plate 6 is connected with fin 2, and fin is connected on the refrigerator fastener 3.
After LED lamp 5 is lighted; Its high light that sends is directly injected LGP 4; Overwhelming majority incident light produces total reflection because the entering angle is bigger behind the entering LGP in plate, be passed to five faces away from LED lamp 5; The side reflective sheeting of LGP is light tight and the process mirror process, can light be reflected back once more.Along with the increase of light order of reflection in the plate, these light will constantly be passed to the surface of engraving groove 8, and the engraving rooved face is coarse and irregular, does not satisfy total reflection condition, and these light are basic point with the engraving groove, inject and then arrive at reflector 1 in the air.Whole soft uniform surface light source of the common formation of the positive a small amount of light that penetrates of all engraving groove luminous points, reflector and LGP.Shown in Figure 1, be connected with above-mentioned total reflection honeycomb fashion LED illuminating lamp backlight through the refrigerator fastener on the one side in the refrigerator chamber or a plurality of.
