Problems solved by technology

However, this passive light-emitting method has limited luminous energy after all. In places with poor light, the human eyes cannot see the information of the sign, which is likely to cause inconvenience to passers-by and even cause disaster. The development of an active luminous sign product is promising. must do

Embodiment 1

[0043] Such as figure 1 As shown, the present invention provides a road light-emitting sign whose brightness can be automatically adjusted, including: a power supply module, a brightness adjustment module 108 and a light-emitting module 107. Control to provide constant current power to the light emitting module 107 . The brightness adjustment module 108 is used to control the brightness of the light emitting module 107 to be adjusted in time according to the intensity of ambient light.

[0044] For example, it is judged that when the ambient light illuminance is strong, the light emitting module 107 is made to emit light with high brightness, and when the ambient light illuminance is weak, the light emitting module 107 is made to emit light with low brightness.

[0045] For example, the control program is preset in the brightness adjustment module 108. When the ambient light illuminance reaches more than 100,000 LUX (outdoor on a sunny day in summer), the light emitting modul...

Embodiment 2

[0047] On the basis of Embodiment 1, this embodiment preferably adopts the following scheme to realize the brightness adjustment function of the brightness adjustment module 108, such as figure 2 As shown, the brightness adjustment module 108 includes a brightness sensing unit 1081, which is installed outside the light emitting module 107 in the open air, and is used to monitor changes in ambient light illumination. The analog quantity of ambient light and illuminance monitored by the sensing unit 1082 is converted into a digital signal that the system can recognize, and the control unit 1083 is connected with the analog-to-digital conversion unit 1082, and is used to output different control signals to the execution unit 1084 according to the above digital signal, and control the execution unit 1084 outputs different brightness data to the light-emitting module 107. In this way, the brightness of the light-emitting module 107 changes in real time under the control of the cont...

Embodiment 3

[0051] On the basis of the above-mentioned embodiments, in order to improve the safety and stability of the circuit operation and ensure that the sign can work normally in the case of power supply interruption, an emergency power supply module can also be set in the circuit, including the battery 104 and solar energy The electric panel 103, the solar electric panel 103 uses solar energy to charge the storage battery.

[0052] An example such as image 3 As shown, an overcharge protection device 106 is provided between the rectifier 102 and the battery 104 to stop charging the battery 104 when the voltage reaches the highest value. The over-discharge protection device 105 is used to stop the external discharge of the battery when the voltage of the battery reaches a minimum value. In this way, the battery can be protected and its service life can be extended.

Abstract

The invention discloses a luminous indicator comprising a power module, a bright adjusting module and at least a luminous module connected in sequence. By real-time monitoring the environment illumination intensity, the luminous indicator ensures the indicator to display different brightness according to different illumination intensity, which can both satisfy the visual need of human eyes and requirements of energy saving and safety.

Description

technical field [0001] The invention relates to the field of municipal traffic, in particular to a luminous sign with adjustable brightness. Background technique [0002] Road signs are an important municipal facility, mainly used in municipal engineering, road indication, street beautification and other fields, including but not limited to the following functions: [0003] Warning: A sign that warns vehicles and pedestrians of dangerous locations. [0004] Prohibition: A sign that prohibits or restricts the traffic behavior of vehicles and pedestrians. [0005] Instructions: signs indicating the movement of vehicles and pedestrians. [0006] Wayfinding: A sign that conveys road direction, location, and distance information. [0007] Tourist area: provide signs for the direction and distance of tourist attractions. [0008] Road construction safety: Signs announcing traffic in road construction areas. [0009] Most of the signboards currently used are passive reflective...
