Ultra-thin LED indicator lamp saving energy

Abstract

The invention relates to an indication sign, in particular to an ultra-thin LED indicator lamp saving energy. The ultra-thin LED indicator lamp saving the energy comprises a lampshade provided with indication patterns in an engraving mode, and LED lamp bars. A light guide board is arranged in the lampshade. The two sides of the light guide board are provided with the LED lamp bars respectively. The light-emitting faces of the LED lamp bars directly face the side face of the light guide board. The bottom face of the light guide board is provided with a light reflection net point. The lampshade is of a three-layer structure formed by overlapping a transparent base layer, a self-luminous material coating and an indication pattern layer, wherein the transparent base layer, the self-luminous material coating and the indication pattern layer are sequentially arranged from inside to outside. According to the ultra-thin LED indicator lamp, as the light guide board is arranged, the light-emitting effect is good, the display brightness of the indicator lamp is improved, the light-emitting brightness of an LED light source is high, and the energy consumption is low; the self-luminous material coating is arranged on the lampshade, even if power is off or the LED lamp is damaged, the indication patterns on the indicator lamp can be displayed for a period of time, and therefore the risk of failure of the indicator lamp under the emergent circumstance can be reduced.

Description

technical field [0001] The invention relates to indicator signs, in particular to an LED ultra-thin energy-saving indicator light. Background technique [0002] Indicator lights are used in many occasions to indicate the exits, passages and various warnings of buildings such as cinemas and shopping malls. The current indicator lights are composed of lamp holders, lampshades, light-emitting lamps and circuits. They are installed in The luminescent lamp behind the lampshade is an ordinary lamp bead with high energy consumption. The entire indicator light is thick and has low brightness; [0003] When the indicator light is in the daytime or when the light is good, the pattern on the lampshade can be seen directly. At night or in the case of poor light, after the power is turned on, the pre-drawn pattern on the lampshade will appear. On the one hand, the energy consumption is high.

[0002] Indicator lights are used in many occasions to indicate the exits, passages and various warnings of buildings such as cinemas and shopping malls. The current indicator lights are composed of lamp holders, lampshades, light-emitting lamps and circuits. They are installed in The luminous lamp behind the lampshade is an ordinary lamp bead with high energy consumption. The entire indicator light is thick and has low brightness;

[0003] When the indicator light is in the daytime or when the light is good, the pattern on the lampshade can be seen directly. At night or in the case of poor light, after the power is turned on, the pre-drawn pattern on the lampshade will appear. On the one hand, the energy consumption is high. At night or when the light is not good, the lights need to be turned on all the time. More importantly, if the power is cut off in an emergency, the indicator lights will not work. Even if a backup power supply is used, frequent maintenance is required. , the lack of complex structure
