Embodiment 1

[0033] figure 1 It is a schematic structural diagram of a refrigerator lighting device provided in Embodiment 1 of the present invention. Such as figure 1 As shown, the refrigerator lighting device may include a first light guide plate 1 and a second light guide plate 2 bonded together, a diffusion film 3 is arranged between the first light guide plate 1 and the second light guide plate 2, and at least A first light emitting diode light bar 4 is arranged on one side, and the light emitted by the first light emitting diode light bar 4 is incident into the first light guide plate 1 . Reflective dots 5 are arranged on the surface of the first light guide plate 1 away from the scattering film 3 . From figure 1 Viewing from the angle of view, from bottom to top are the first light guide plate 1 , the scattering film 3 and the second light guide plate 2 , and the lower surface of the first light guide plate 1 is provided with reflective dots 5 .

Embodiment 2

[0045] Figure 5 It is a schematic structural diagram of a refrigerator lighting device provided in Embodiment 2 of the present invention, Figure 6 Another structural schematic diagram of the refrigerator lighting device provided by Embodiment 2 of the present invention. Such as Figure 5 and Figure 6 As shown, on the basis of the above-mentioned technical solution, the refrigerator lighting device includes a first light guide plate 1 and a lampshade 9 with a scattering function. At least one side of the first light guide plate 1 is provided with a first light-emitting diode light bar 4 . The light emitted by an LED strip 4 is incident into the first light guide plate 1 . Wherein, the lampshade 9 can be made of a material with a scattering function, or the surface of the lampshade 9 adjacent to the first light guide plate 1 is coated with a scattering material, which can scatter the light emitted from the first light guide plate 1 . The lampshade 9 surrounds the first li...

Abstract

The invention provides a refrigerator lighting device and a refrigerator. The refrigerator lighting device comprises a first light guide plate and a second light guide plate, wherein the first light guide plate and the second light guide plate adhere to each other. A scattering film is arranged between the first light guide plate and the second light guide plate, a first light-emitting diode light bar is arranged on at least one side of the first light guide plate, light emitted by the first light-emitting diode light bar enters the first light guide plate, and light-reflecting net points are arranged on the surface, far away from the scattering film, of the first light guide plate. The refrigerator lighting device can solve the problem that an existing lighting device is large in size, and an occupied space of the lighting device in the refrigerator is reduced.

Description

technical field [0001] The invention relates to lighting technology, in particular to a refrigerator lighting device and a refrigerator. Background technique [0002] Light emitting diodes (Light Emitting Diode, LED for short) have high luminous efficiency and long service life, and are more and more widely used in various lighting devices. However, since LEDs are point light sources, they have certain limitations in large-area lighting. When the number of LEDs is fixed, the combined large-area lighting device has poor uniformity of illumination; if the number of LEDs is increased, the LED The density of the arrangement is improved to improve the uniformity, and the corresponding cost is also increased. [0003] The above-mentioned lighting device using LED as the light source can be applied to the back panel lighting of the refrigerator, which usually uses an acrylic plate as the light guide plate, and the front and back of the light guide plate are respectively provided w...
