Prison lighting solutions

Current situation of prison lighting:

According to an uncompleted statistic, the annual electricity consumption of factories in the national prison is about 43649.28 kwh, about 223 million 976 thousand yuan. If add the other factories, office buildings and dormitories, the cost of lighting is an amazing figure. In addition, poor color rendering, low color reduction, delayed startup, and power consumption are the Shortcomings of traditional light source, it’s detrimental to prison administration.

    The traditional light source is a point light source, incomplete coverage can easily lead to blind area monitoring, which can be used by criminals.

    Infrared light is invisible, the effect of light supply is not obvious, black-and-white imaging, low clarity. When camera monitoring depth and field of view are inconsistent, it is easy to cause deformation and backlight.

    It will take 8-10 minutes to restart the traditional light source. During this period, both the lighting and video surveillance can’t work immediately, which is a security vulnerability that can be exploited.

    The light will have an impact on the prisoner's mood. High color temperature easily makes people feel irritable, nervous, depressed and other negative emotions.

    The energy consumption of ordinary prisons is high, resulting in power waste and environmental pollution.


    Through these illuminating States, we find that the color, illumination angle and delay of light source have important influence on prison safety. Good lighting environment can provide support for building a safe and healthy prison environment. Besides, prison lighting not only has a significant impact on safety, but also affects mental health of prisoners. Therefore, we need to pay attention to prison lighting, do a good job in prison lighting, and provide a safe and healthy lighting environment for prisons.


Special floodlight must be used in the warning area.

It’s necessary to purchase lamps with good sealing properties. The level of protection must not be less than IP65, and good heat dissipation to prevent excessive temperature; Moderate light intensity and uniform illumination can prevent visual fatigue, effectively prevent the adverse effects caused by visual blind area, and improve the safety factor. The areas with high corrosion gas content such as acid and alkali in the air should be used with good corrosion resistance lamps, drop proof, spray proof, splash proof, spray proof, water tightness and pressurized water tight lamps and lanterns. The corrosion may lead to the unsafety of the lamps, and should have adequate rust protection and protection.

 

      The energy is coupled to the bulb by high frequency induction magnetic field, which ionize the gas avalanche in the bulb to form plasma, and when the excited plasma atoms return to the original state, the energy obtained will be radiated in the form of 253.7nm ultraviolet rays to complete an energy conversion process. The phosphors inside the bulb emit visible light by ultraviolet excitation.
