1. Field of the Invention
The present invention relates to a lamp tube and a lamp fixture for holding the lamp tube, and more particularly to a lamp tube and a lamp fixture with a fire sensing capability.
2. Description of Related Art
Fire is one of the common disasters in today's society. Fires are mostly started from a spark, and the spark gradually grows into a fire disaster. The fire disaster, which is hard to be extinguished, threatens people's lives, causes huge property damages, and increases social costs for putting out the fire. When the fire is weak, it is easy to extinguish the fire. Therefore, if the spark can be discovered as soon as possible, the damage and threat can be minimized.
A conventional flame detector can detect a fire source in a space by sensing smoke, concentration of carbon dioxide or temperature. When a fire occurs, a fire sprinkler firstly sprinkles water over the fire to extinguish the fire. Meanwhile, firemen are notified to assist people in an emergency evacuation. Because of the installation of the flame detector, people can be evacuated in a timely manner to reduce life threatening and the firemen can be immediately notified to extinguish fire so as to prevent the fire from continuing to expand and reduce property damages.
The conventional flame detector is installed at a fixed location within a space. However, fire can occur at any locations in the space. When the location where the fire occurs is far away from the installation location of the flame detector, the flame detector may fail to detect the fire source as soon as possible, such that a purpose of timely evacuating people cannot be achieved. Moreover, in the installation of flame detector, the flame detector needs a wire to be electrically connected to a power source to be workable. Accordingly, it is inconvenient for a user to connect the wire to the flame detector.
Since the location of the conventional flame detector is fixed, the occurrence of the fire cannot be detected accurately in a timely manner. In addition, the conventional flame detector needs a power line to be connected to a power source to acquire electric energy to be workable. Therefore, the installation of the conventional flame detector is inconvenient. An objective of the present invention is to provide a lamp tube with sensing capability and a lamp fixture with sensing capability, and the lamp tube and the lamp fixture can be easily installed in various locations.
In order to achieve the aforementioned objective, the lamp tube with sensing capability in the present invention comprises:
a lamp tube body comprising:
Since the lamp tube with sensing capability includes the sensing unit, the sensing unit can detect the occurrence of the fire and output a fire alarm signal to notify the firemen and evaluate the people nearby when the fire occurs. The shape of the lamp tube with sensing capability is the same as the normal lamp tube and the sensing tube can be directly installed in the current lamp fixture to receive power without additionally connecting the external power source via the power line to acquire the power energy. In addition, the lamp fixtures are the conventional equipments, which already exist and are normally installed at various locations within the room. When the lamp tube with sensing capability in the present invention is implemented, the original lamp tube is removed and replaced with the lamp tube with sensing capability in the present invention to detect the occurrence of the fire within the room so as to enhance the convenience of the installation.
A lamp fixture with sensing capability of the present invention comprises:
a power converting unit electrically connected to an external power source to receive an AC power, convert the AC power to a DC power, and output the DC power; and
a sensing unit electrically connected to the power converting unit for receiving the DC power and generating a fire alarm signal when the sensing unit detects an occurrence of a fire.
Since the lamp tube with sensing capability includes the sensing unit, the sensing unit can detect the occurrence of the fire and correspondingly output a fire alarm signal to notify the firemen or warn the people nearby to evacuate. The lamp fixture with sensing capability is for installing the LED lamp tube and is installed during interior decoration of the room. A bigger room would have more LED lamp tubes. The LED lamp tubes are evenly installed in the room to provide enough illumination to lighten the room. Therefore, the number of the lamp fixtures with sensing capability is increased and the lamp fixtures with sensing capability are evenly installed in the room. The lamp fixtures with sensing capability in the room include the sensing units respectively, so the condition at each of the corners can be detected to find out the occurrence of the fire so as to react in a timely manner.
These and other aspects of the embodiments herein will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings.
Please refer to
The power converting unit 11 is electrically connected to an external power source 20 for receiving alternating current (AC) power and converts the AC power to output a direct current (DC) power. The LED strip 12 is electrically connected to the power source converting unit 11 for receiving the DC power to illuminate the LED strip 12.
The sensing unit 13 is electrically connected to the power converting unit 11 for receiving the DC power, which is used for operating the sensing unit 13. When the sensing unit 13 detects an occurrence of a fire, the sensing unit 13 outputs a fire alarm signal to notify the firemen or evaluate the people nearby in a timely manner.

With reference to
The smoke sensing module 131 is used to sense whether smoke exists in the room and finds out if a smoke concentration is higher than a threshold value.
When the smoke sensing module 131 detects that the smoke concentration is higher than the threshold value in the room, the fire alarm signal is generated and the people nearby are notified to evacuate from the room.
The carbon monoxide sensing module 132 is for sensing whether carbon monoxide exists in the room. When the carbon monoxide exists in the air within the room, the alarm signal is generated to notify the firemen to take action. When the carbon monoxide exists in the air within the room, this means that the carbon monoxide is produced by incomplete combustion from use of the water heater or the gas stove. Since carbon monoxide is easier to be absorbed by human beings compared to oxygen, the humans cannot obtain the oxygen, resulting in hypoxia so as to lead to death. In addition, carbon monoxide is odorless and colorless, and it is not easy to be detected. The existence of carbon monoxide in the air within the room won't cause fire, but carbon monoxide is deadly dangerous for humans. Therefore, the carbon monoxide sensing module 132 is used to sense the air within the room. As long as the carbon monoxide exists in the air within the room, the firemen are notified to take action to avoid the occurrence of the incident.
The temperature sensing module 133 is for sensing the ambient temperature within the room. When the ambient temperature is higher than a threshold temperature, the alarm signal is generated to notify the firemen to take action and warn the people nearby to evacuate. Moreover, the temperature sensing module 133 further has an additional function. When the space of the room is huge, the temperature within the room at each of the corners won't be the same. For example, the overall space in an open office is huge, and the distribution of the temperature is uneven when air conditioning is turned on during summer or when heater is turned on during winter. It would cause the room colder at one side and hotter at the other side. Therefore, if one of the normal lamp tubes in one of the lamp fixtures in the office is replaced with the lamp tube with sensing capability 1, the temperature sensing module 133 in each of the lamp tubes with sensing capability 1 can sense the ambient temperature so as to detect the temperature at each corner of the office. The air conditioning system can be adjusted in accordance with the temperature at each corner to balance the temperature at each corner of the office so as to avoid uneven distribution of the temperature.
The carbon dioxide sensing module 134 is for sensing the concentration of the carbon dioxide within the room. When the concentration of the carbon dioxide in the room is greater than a concentration threshold value, the alarm signal is generated to notify the firemen to take action. In addition, the carbon dioxide sensing module 134 further has an additional function. When there are too many people in the room, the carbon dioxide concentration is increased in the room. The carbon dioxide won't lead to death, but people will be sleepy when the concentration of the carbon dioxide is high. Therefore, the carbon dioxide sensing module 134 can sense the concentration of the carbon dioxide and the oxygen content within the room can be controlled in accordance with the concentration of the carbon dioxide by adjusting the air conditioning system.
The sensing unit 13 further includes a power line signal transmitting module 135, a wireless module 136, and a warning module 137. The power line signal transmitting module 135 is electrically connected to the smoke sensing module 131, the carbon monoxide sensing module 132, and the temperature sensing module 133 for receiving the fire alarm signal and the fire alarm signal is transmitted to a power line signal receiving module 30 via a power line, which is connected between the power converting unit 11 and the external power source 20. Thereafter, the fire alarm signal is transmitted to a server 40 to timely notify the firemen.
The wireless module 136 is used to transmit data as the power line signal transmitting module 135, but the fire alarm signal is wirelessly transmitted by the wireless module 136 to a wireless receiving module 50 and further transmitted to the server 40 from the wireless receiving module 50 to notify the firemen.
The warning module 137 is for generating an alarm when the fire alarm signal is received to notify the people nearby to evacuate.
With reference to
The power converting unit 11 is electrically connected to the external power source 20 for receiving the AC power and converting the AC power to DC power to output the DC power. The sensing unit 13 is electrically connected to the power converting unit 11 for receiving the DC power, which is used for operating the sensing unit 13. When the sensing unit 13 detects an occurrence of a fire, a fire alarm signal is generated to notify the firemen or people nearby to evacuate in a timely manner.
The lamp fixture with sensing capability 4 is for installing at least one LED tube 5. When the LED tube 5 is installed on the lamp fixture with sensing capability 4, the LED tube 5 is electrically connected to the power converting unit 11 for receiving the DC power to illuminate the LED tube 5.
The sensing unit 13 of the lamp fixture with sensing capability 4 is similar to the sensing unit 13 of the lamp tube with sensing capability 1. The difference is that the sensing unit 13 of the lamp fixture with sensing capability 4 is directly installed on the lamp fixture with sensing capability 4 instead of being installed within the lamp tube.
Since the lamp fixture with sensing capability 4 is the lamp fixture for installing the LED tube 5, the lamp fixtures with sensing capability 4 have been installed during interior decoration of the house. When the house is bigger, the number of the installation of the lamps is increased and the lamps are evenly installed in the room to provide sufficient light within the room. Therefore, the lamp fixtures with sensing capability 4 are evenly installed within the room. Each of the lamp fixtures with sensing capability 4 in the room includes the sensing unit 13, so each corner within the room can be detected to find out if fire occurs so as to respond timely and proceed properly.
