As shown in FIG. 6-7, the second surface light source body 122 and the top wall 112 of the inner liner have a flash seam 50. In the present invention, in order to cover the flash seam 16, the second surface light source body 122 is away from the first surface. One end of the light source body 121 is provided with a decorative lamp 15, that is, the decorative lamp 15 is disposed adjacent to a door body (not shown) of the refrigerating compartment 10. Specifically, a second trim strip 14 is disposed at an end of the second surface light source body 122 away from the first surface light source body 121, and the decorative light 15 is disposed on the second trim strip 14. Further, the decorative light 15 includes a light source 151 and a light cover 152 that guides light emitted from the light source 151 to the top wall 112 of the inner casing to cover the flash seam 50.

The L-shaped surface light source assembly 12 further includes a first LED light bar (not shown) disposed in the first surface light source body 121 and a second LED light bar (not shown) disposed in the second surface light source body 122. . Preferably, the first LED light bar is disposed at one end of the first surface light source body 121 away from the second surface light source body 122, and the second LED light bar is disposed at an end of the second surface light source body 122 away from the first surface light source body 121. The light emitted by the two LED strips respectively enters the first surface light source body 121 and the second surface light source body 122 to illuminate the first surface light source body 121 and the second surface light source body 122, thereby increasing the inside of the refrigerating compartment 10. The illuminating area allows for good illumination inside the refrigerator compartment 10. Among them, only one LED strip emits light of adjustable color, and the other LED strip emits white light of a single color. The first surface light source body 121 and the second surface light source body 122 each include a reflective sheet (not shown), a light guide plate (not shown), a diffusion sheet (not shown), a film sheet (not shown), and the like. It has a frame structure made of aluminum alloy.

In the present invention, the L-profile source assembly 12 can emit different colored lights to correspond to different functional indications within the refrigerating compartment 10. The light emitted by the second LED strip disposed at the end of the second surface light source body 122 is adjustable color light, which includes LED lights capable of emitting red, green and blue colors and controlling red, green and blue colors. The color LED light switch and the brightness driving circuit (not shown), the driving circuit uses PWM signal to control the opening and closing of the red, green and blue LED lights, and adjusts the brightness of the three color lights and mixes with each other, thereby To form more color effects, the refrigerator (not shown) further includes a temperature sensor (not shown) for sensing the temperature in the refrigerating compartment 10, the temperature sensor is electrically connected to the driving circuit, and the driving circuit is configured to be based on the temperature sensor. The feedback temperature signal controls the switching and brightness of the red, green and blue LED lights. The first LED strip disposed at the end of the first surface light source body 121 emits only a single color of white light. The light emitted by the first LED strip and the second LED strip respectively enters from the L-shaped surface light source assembly 12 and meets at the arcuate junction 123 of the first surface light source body 121 and the second surface light source body 122 to satisfy the illumination. At the same time, the effect of colorful light is also achieved.

Specifically, as shown in FIG. 8, the second LED light bar includes an LED red light, an LED green light, an LED blue light, and a driving circuit that controls three light switches and brightness. LED red light, LED green light, LED blue light positive electrode connected to LED_VDD driving voltage, the negative electrode is connected with LED_G, LED_R, LED_B control signal respectively, these three control signals respectively pass through current limiting resistors R404, R405, R406 and MOS tube respectively Q401, Q402, and Q403 are electrically connected, and the MOS transistors are respectively controlled by LED_PWM_R, LED_PWM_G, and LED_PWM_B signals, and the LED_PWM_R, LED_PWM_G, and LED_PWM_B signals are electrically connected to the temperature sensor of the refrigerator. The LED light bar disposed at the end of the second surface light source body 122 emits light according to the principle of changing the intensity of the current flowing through the PN junction under the action of the diode driving voltage. As can be seen from FIG. 9, the LED_PWM_R input is high. Normally, the MOS transistor Q401 is turned on, LED_VDD acts on the LED red light and forms a loop with GND. The LED red light is driven by a suitable current limiting resistor R404. When the LED_PWM_R input is low, the MOS transistor Q401 is turned off, and the LED_VDD acts on LED red light but formed an open circuit with GND, LED red light no voltage current through, LED red light is extinguished. Similarly, the LED green light and the LED blue light are also controlled to be illuminated and extinguished by driving the high and low levels of LED_PWM_G and LED_PWM_B, respectively.

When LED_PWM_R inputs PWM signal, MOS tube Q401 becomes high frequency switch under the control of PWM signal, converts LED_VDD voltage acting on LED red light into high frequency square wave signal, and smoothes filtering by filter capacitor D604 to realize voltage transformation The magnitude of the voltage transformation can be adjusted by adjusting the duty cycle of the PWM signal to change the current flowing through the LED red light to adjust the luminous intensity. Similarly, the LED green light and the LED blue light are also adjusted to the luminous intensity by inputting the PWM signals LED_PWM_G and LED_PWM_B, respectively. Thereby, the temperature sensor senses the temperature at the corresponding position of the cooling compartment, and the driving circuit controls the light emitting effect of the second LED light bar according to the temperature signal fed back by the temperature sensor, thereby realizing controlling the LED red light, the LED green light, and the LED at different temperatures. The blue light switches and their respective luminous intensities, the L-shaped surface light source assembly 12 display different colors.
