TWIN DOME DUAL POWER with ALARMWe have noticed that many sites are using aviation lights working on 230 AC. When there is a power failure the light will not switch on until the generator starts. Due to time delay provided in AMF panel or generator’s failure it is likely that generator may not switch on for few hours. This means that the site will not be compliant with the safety requirements. Also if the only light that is installed fails then again there is no light on tower. It could take a few days to notice and replace the light. To overcome this we propose a dual input voltage light which works as follows:
TWIN DOME, DUAL VOLTAGE with STANDBYThe model consists of TWO lights that are connected to a single Control panel. The control panel ensure that when the first light fails to switch ON (or consumes less than 65% of rated current) then the standby light is switched ON. In case of failure of light, additionally there is a Light Failure alarm provided thru potential free contacts. Control panel ensures that in case there is a failure of first light then the second one is automatically switched ON. Failure is defined as total failure or if the power consumption reduces to less than 65% (or as defined by user) In this case there is a NMS alarm (potential free contacts) is also activated. Appropriate junction box is provided to connect input cable. 3 core cable is required. Features of each light are:
SENSORSWe provide single photoelectric sensor for the two lights. The sensor is mounted outside the shelter. Sensor is provided with it's own mounting arrangement. Mounting arrangementWe provide a single stand that can mount two lights as shown in picture above. All the mounting accessories are provided. No cables are provided. Uniform light intensity feature (Common to all models)This is one of the two requirements of ICAO for aviation lights (the other being light intensity). Since the time, LED lights were introduced, it was a challenge as to how to produce uniform intensity from directional LEDs. Our engineers have come out with a solution, finally!! Due to the hard nature of PCB on which LEDs are mounted, most the lights in the market have 6 or 8 faces. Since the light from LED's is directional in nature, the light from such aviation light is not uniform but is a set of 6 or 8 streaks. Some people use secondary optics (Lenses) to make the intensity uniform, thereby wasting light intensity. However, in case of Spaceage lights, the light pattern is uniform on account of the large number of LED's and special base on which such LEDs are mounted that is perfectly curved. If we look from the top (PLAN view), then the light pattern will be as follows:
We actually took pictures of Light pattern at 1m and at 3 meters, we can see bright and dark spots due to varying intensity produced by such lights.
One of the popular models in market (at 3 m and at 1m) Other popular models in market (at 3 m and at 1m)
Spaceage Light pattern at 1m
Of course, it is matter of common knowledge that the light has to have uniform intensity. Incidentally, this is ICAO requirement too. Note: We reserve the right to revise features at any time, without any prior notice |
