Abstract
The utility model discloses a total-reflection cellular backlight LED (Light-Emitting Diode) head lamp of a refrigerator and a refrigerator using the head lamp. The head lamp comprises a plurality of patch LED lamps arranged on the front surface of a lamp panel, wherein the light emitting surfaces of the LED lamps cling with one side edge of a light guide plate. Other three side edges of the light guide plate are stuck with reflective paper. One surface of the light guide plate is carved with a cellular carved groove, and one side of the light guide plate provided with the carved groove is provided with a reflective plate. The lamp panel, the light guide plate and the reflective plate are connected on a refrigerator buckling piece, and a closed hollow cavity is formed between the light guide plate and the reflective plate. The head lamp has the advantages of safety, low power consumption, low heat, large luminous surface and soft and uniform light. The head lamp does not have an extreme concentration area, and the head lamp can bring fresh and beautiful use feelings for users day and night.
Description
Technical field:
The utility model 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 purpose of the utility model is to provide a kind of refrigerator total reflection honeycomb fashion LED illuminating lamp backlight, and this installs simplicity of design, and processing technology is ripe, and simple installation is reliable.
The utility model 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.
The utility model technical solution problem 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, the beneficial effect of the utility model 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, the refrigerator total reflection honeycomb fashion LED illuminating lamp backlight of the utility model, 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 utility model similar lighting device volume after installing takies reduction and reaches 60% at most.
Description of drawings:
Fig. 1 is the structural representation of the utility model refrigerator total reflection honeycomb fashion 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 the center line of the utility model.
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 utility model 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.
