subject: Tips To Save Energy With Police Car Lights [print this page] Police car lights and car police siren are equipment, which help you get the attention of other motorists, thereby requesting for a freeway or propagating a cautionary signal. There has been plenty of innovation and advancement in technology which has ensured that the modern emergency lights and sirens are extremely effective. A very important aspect of these emergency lights is the fact that they need to conserve energy. This is because emergency lights like light bars mounted on vehicle roofs might need to be operated for long hours at a stretch. So, it is imperative that you use equipment that is energy efficient so that you can rely on the equipment to last through a critical mission, especially when it is tough to carry backup power supply at all times.
A good idea to conserve energy is to use police car lights that make use of light emitting diodes. LEDs save energy in more than one way. For the same wattage, LEDs can produce a lot more luminosity compared to other sources of light. So, although halogen and xenon light heads are quite popular it is a good idea to make use of LED light heads which can give you brightness without really consuming too much energy. Car police siren and emergency lights both tend to make use of 12 24V DC power supply which is quite less. If your emergency lights have to function for longer periods with such a low power supply, you have to make use of LED light heads and LED strobes.
Police car lights making use of LEDs can save energy also because of the low heat dissipation of the LEDs. In spite of being used for long hours, LEDs don't get overly heated up and this is where a major chunk of the power saving happens. Moreover, these emergency lighting circuits don't have high currents flowing through them and that keeps the heat wastage low as well. The amperage could be lower than 5A in light bars and in equipment like car police siren the amperage could be sometimes lower than 1A. In spite of this low amperage there is ample security against voltage spikes, short circuiting and reverse polarity.
There are many different types of emergency lighting equipment which try to make efficient use of energy and conserve energy. Police car lights with intensity control modes can lower power consumption considering that you can use cruise lighting or low intensity modes in dark, when bright flashy lighting is not necessarily required to attract attention. Similarly, additional optical elements are used to make the most of the lighting emitted by the LEDs. For example, optic spreader filters and Fresnel inner and outer lenses are used to collect the LED lighting and spread the coverage. To enhance penetration and beam angle, parabolic reflectors are also used in some cases. Car police siren equipment is also used in sync with emergency lights like light bars for maximum effect, especially when there is lot of ambient light or noise.
