Specific embodiment
Below embodiment of the present utility model is elaborated, the present embodiment is being front with technical solutions of the utility model
Put and implemented, give detailed embodiment and specific operating process, but protection domain of the present utility model does not limit
In following embodiments.
Referring to Fig. 1, Fig. 2, present embodiment discloses a kind of refrigerator LED area light source, including temp. controlling box 2 and be arranged at temperature control
LED lamp panel 1 on box 2 and diffuser plate mask 3, temp. controlling box 2 is used for supporting LED lamp panel 1 and diffuser plate mask 3.In LED lamp panel 1
It is provided with multiple LED lamp bead 11, multiple LED lamp bead 11 are uniformly arranged in a row in LED lamp panel 1, for example, can be equal in a row
Three LED lamp bead 11 of even arrangement.Divider resistance 13, adapter 14 and pcb board 15 are additionally provided with LED lamp panel 1.LED lamp bead 11
It is covered with lens 12, diffuser plate mask 3 is be arranged in parallel with LED lamp panel 1, and diffuser plate mask 3 is located at the LED lamp bead of LED lamp panel 1
The side of 11 exiting surface, the distance between diffuser plate mask 3 and LED lamp panel 1 are 20～25mm, and distance closely easily produces very much light
, dazzle in source hot spot；Far it is easily reduced very much the brightness of area source, or even the defect of diffuser plate mask 3 edge no brightness occurs,
Thus diffuser plate mask 3 and LED lamp panel 1 are arranged on suitable in the distance and can reach the area source effect that brightness is high, uniformity is good.
Wherein, LED lamp bead 11 can adopt adopting surface mounted LED light emitting diode, glow color be white, colour temperature be 2700～
6500K, color rendering index minimum 80, representative value is 82, and half light intensity angle is 120 °.Lens 12 are the circular PMMA lens of hot spot,
Its a diameter of Φ 13mm, light transmittance is 92%, and refractive index is 1.49, and lens 12 can change LED lamp bead 11 light source by refraction and send out
The radiation direction going out, increases lighting angle and the uniformity of light.Divider resistance 13 is many 300 ohm of resistance, according to every 4
A road loop provides stable 3.3VDC running voltage to a LED lamp bead 11.Adapter 14 is a side-mounted power supply
Terminal, is connected with the wire harness of LED lamp panel 1, powers source as LED lamp panel 112VDC.Pcb board 15 is the base material of LED lamp panel 1,
Comprise wiring route, meet the flame retardant rating of UL 94V-0.
Diffuser plate mask 3 is frosting in the one side towards LED lamp panel 1, is provided with one layer of all light oxidant layer outside frosting.By
Increased one layer of all light oxidant layer outside the frosting of diffuser plate mask 3, possess high transmission rate, the optical signature such as high diffusibility,
Light fully can be scattered, strengthen uniformity, on the premise of reaching good light transmittance, possess good light source point
Battle array shielding.The thickness of this diffuser plate mask 3 is 1.5mm, and light transmittance is 50%～60%；Its frosting mist degree be 99.5 ±
1%.
After supplying 12VDC power supply to LED lamp panel 1 by adapter 14, acted on by the partial pressure of divider resistance 13, every
LED lamp bead 11 obtains stable 3.3VDC voltage respectively, lights luminous, and light reflects after lens 12 and sends, and changes former
The light trend come is so as to distribution face homogenization；Light increases emission of light angle so as to shine after lens 12 simultaneously
Penetrate face wider.Dissipated through all light oxidant layer of its frosting again when diffuser plate mask 3 is reached by the light after lens 12
Penetrate so as to the light distribution on diffuser plate mask 3 surface obtains full and uniform, it is achieved thereby that the purpose of area source, give brightness
Uniform area source effect.
In the design of refrigerator lighting, can be according to the size of illuminated area, the factor such as volume of refrigerator lighting, by changing
The size of LED lamp bead 11, the quantity of lens 12 and diffuser plate mask 3, shape etc., the area source effect required for realizing, strengthen
The experience sense of user is subject to.
This utility model is simple for structure, easy to assembly, low cost, portable strong, can be applicable in refrigerator lighting.
By this utility model, not only can solve the dazzle of point source, and achieve the effect of area source, enhance selling of refrigerator
Point.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model
Within the scope of shield.
