[0024] Example

[0025] The technical solution of the utility model is: an energy-saving card cloth light box, comprising: a frame profile 1, wherein a mounting groove is arranged inside the frame for installing a bottom plate 2; the bottom plate 2 is fixedly connected to the frame profile 1 to form a receiving space with an open end; a back plate 3 is fixedly arranged in the receiving space for reflecting the light of an LED light strip 4, and the back plate 3 adopts tin foil with a reflectivity higher than 97% or PET reflective paper with a reflectivity higher than 95%; a plurality of LED light strips 4 are fixedly arranged in the receiving space and arranged regularly and equidistantly, and the length extension direction of each of the LED light strips 4 is consistent with the length extension direction of the frame profile 1, and the LED light strips 4 are greater than or equal to 200lm / w; a power supply 6, and the power supply 6 is respectively connected to the mains and the plurality of LED light strips 4; a card cloth screen 5 is detachably connected to the frame profile 1 to close the opening of the receiving space.

[0026] The technical solution of this embodiment uses tin foil with a reflectivity higher than 97% or PET reflective paper with a reflectivity higher than 95% as the backboard 3, which can fully and evenly reflect the light generated by the LED light bar 4. The LED light bar 4 uses a model higher than 200lm / w and uses a special lens light bar, which has a higher luminous efficiency. When the card cloth screen 5 needs to achieve the same brightness, the card cloth light box of this embodiment requires less electric energy, thereby achieving energy saving. Using the technical solution of this embodiment, when the power consumption per square is about 40W, the surface brightness can reach 4500LUX; when the power consumption per square is about 30W, the surface brightness can reach 3500LUX; when the power consumption per square is about 25W, the surface brightness can reach 2700LUX.

[0027] Preferably, it also includes: a light sensor, which is arranged outside the accommodating space and is used to collect the light intensity of the environment in which the Kabu light box is located; the power supply 6 is also connected to the light sensor signal, and the light sensor generates electric signals of different intensities based on different light intensities to trigger different electronic switches in the power supply 6 to provide different electric signals to the LED light strip 4, thereby changing the power of the LED light strip 4.

[0028] The technical solution of this embodiment also sets a light sensor outside the accommodating space of the light box. The light sensor can collect light intensity in real time and generate a corresponding electrical signal. The power supply 6 receives the electrical signal. Electrical signals of different intensities control different electronic switches in the power supply 6 to turn on for power supply. This part of the hardware circuit is a very common hardware control circuit, such as a comparator combined with a thyristor electronic switch, which will not be elaborated here.

[0029] Preferably, the conversion efficiency of the power supply 6 is greater than 90%, thereby further improving the power utilization efficiency of the entire light box and saving power.

[0030] Preferably, a power source 6 with a conversion efficiency of 90% can also be used. The higher the conversion efficiency of the power source 6 is, the more it can reduce the ineffective loss of electric energy during long-term operation and use, thereby improving the economic benefits of the entire Kabu light box.

[0031] Preferably, the power supply 6 is configured close to the side of the Kabu light box, and the output cable 7 of the power supply 6 is made of high-temperature resistant and flame-retardant wire and is fixed to the LED light strip 4 using wiring terminals or tinning, with electrical tape wrapped around the surface, and the output cable 7 of the power supply 6 is applied and fixed to the base plate 2.

[0032] Since the LED light bar 4 generates heat obviously, a high temperature resistant and flame retardant power supply 6 output cable 7 is used to improve the reliability of the entire device. At the same time, the output cable 7 is arranged on the bottom plate 2 and fixed to further extend the service life.

[0033] Preferably, the output cable 7 of the power supply 6 is less than 1.5 m in length.

[0034] In the prior art, the power supply 6 is often configured far away from the card light box, so that the power supply 6 output cable 7 connecting the output end of the power supply 6 and the LED light strip 4 is relatively long. Since the cable itself has line loss, the lower the current carrying capacity of the cable, the greater the resistance and the more obvious the voltage drop. In addition, the voltage at the output end of the power supply 6 is lower than the mains, so the voltage drop will be more obvious, which will affect the effective voltage and power generation received by the LED light strip 4. Therefore, the technical solution of this embodiment, which configures the power supply 6 close to the card light box, can effectively solve the above problems, reduce ineffective energy consumption, and improve the luminous efficiency of the LED light strip 4.

[0035] Preferably, a clock unit is disposed inside the power supply 6, and the clock unit is configured to shut off the power supply to the LED light strip 4 within a predetermined clock range.

[0036] The technical solution of this embodiment configures a clock unit inside the power supply 6. The clock unit is composed of a crystal oscillator, a frequency divider, a counter and other parts, so as to achieve time control management of the Kabu light box, which only lights up within a predetermined time, solves energy problems and reduces the possibility of complaints from residents.

[0037] Preferably, the card cloth screen 5 is made of card cloth material with a light transmittance higher than 55%.

[0038] In order to further improve energy efficiency, the cardboard screen 5 uses a cardboard material with a light transmittance of more than 55%, which is beneficial to reduce energy consumption.

[0039] Preferably, the plurality of LED light strips 4 are electrically connected to the power supply 6 in parallel, and the distance between adjacent LED light strips 4 ranges from 100 mm to 200 mm. Preferably, 110 mm can be used. This can fully utilize energy and obtain a uniform light display effect of the card cloth light box.

[0040] Preferably, the power supply 6 is a 220V AC to 12-24V DC power supply, and the rated power of the power supply 6 is in the range of 200W-400W, preferably 300W.

[0041] Preferably, it further comprises an energy storage battery, the output end of the energy storage battery is electrically connected to the power supply 6 , and the power supply 6 provides electrical energy to the LED light strip 4 .
