Abstract
The utility model discloses an indicator for a life jacket, which is characterized in that a high brightness LED tube is adopted as a luminous source and positioned inside a lampshade on a housing, a battery and a control circuit board are positioned in the housing, the battery is respectively connected with and supplied for the control circuit board and the luminous source, two water contact switches are positioned directly on the lateral side of the housing, the head of a probe is extended out of the housing, the tail of the probe is positioned in the housing and connected with the control circuit board, acting as a control switch. The utility model has the advantages of increasing the visual distance of the indicator for the life jacket because the high brightness LED tube is adopted, enhancing the safety and reducing the size because the wire is removed, timely testing the perfectiveness of the luminous source and the battery because the contact switches are positioned on the lateral side of the housing, continuing to light for a short period when the indicator is out of water because a time delay circuit is positioned in the control circuit board, ensuring the luminous source to work a short period when the water contact switches are out of the water surface.
Description
One, technical field
The utility model relates to a kind of Escape and Survival Equipment, specifically is a kind of life jacket Position indication lamp, and it is installed on the life jacket, is used for various boats and ships, naval vessels, operation at sea personnel in its drowning position of indicating when in danger waterborne at night.
Two, background technology
The life jacket Position indication lamp is a kind of secondary lifesaving equipment according to maritime sector relevant criterion indispensability on life jacket, and it is used for water surface distress personnel in the location at night, is convenient to the rescue group and in time searches and rescues.Common lifesaving Position indication lamp is made up of circuit part in luminary, lampshade, lamp socket and the lamp socket, owing to adopt general dry battery, its volume, weight are bigger, battery life is shorter, need often to change, particularly the low-temperature characteristics of dry storage battery is very poor, and temperature is low more more can't normal operation, and dry storage battery is no longer worked when temperature is lower than-2 ℃; In addition, the switch of this lamp is a manual switch, and behind the man overboard usually because panic and forget and open switch or be difficult to touch switch, thereby the normal rescue of influence.One key name is called " life jacket Position indication lamp ", in the Chinese utility model patent of publication number CN2480288, with the battery altering in the former life jacket Position indication lamp is lithium cell, and link to each other by the lead water trigger switch that the control circuit in the Position indication lamp and lamp is outer, the brightness of lamp is increased, prolonged service life, owing to used the water trigger switch, also need not M/C can turn on light.But this life light also has its shortcoming, 1, bulb adopts conventional fluorescent tube, because conventional fluorescent tube consumption of current is big, when luminosity meets the requirements of 0.75CD, when the battery of capacity such as employing, its work life has only about 1/3 of LED fluorescent tube, extends working time if desired then must increase capacity of cell, this corresponding again volume that increases life light.2, the connection mode of lead and water trigger switch has not only increased cost, and the corresponding life light whole reliability that reduced of increase number of parts meeting, water trigger switch long period of soaking is intake in water the time easily, even after dried up, still may there be moisture in switch inside, causes stealthy conduction and expends electric power.3, this Position indication lamp is not easy to detect the integrity of bulb and battery.
Three, utility model content
Technical problem to be solved in the utility model provides a kind of life jacket Position indication lamp more energy-conservation on the basis of satisfying light intensity and work-hours, and this life jacket has been removed lead, makes more compact structure, and reliability is higher, also makes the more convenient detection of life jacket Position indication lamp.
A kind of life jacket Position indication lamp described in the utility model, comprise housing, lampshade, light emitting source, lithium cell, two water contact switchs and control circuit board, described light emitting source is installed in the lampshade, lampshade is installed on the housing, lithium cell and control circuit board are installed in the housing, lithium cell is connected respectively to both power supplies with control circuit board and light emitting source, the water contact switch is connected the effect of playing master cock with control circuit board, after lamp falls into the water, two water contact switchs are by the water conducting, two water contact switchs are directly arranged in the housing side, and its probe head stretches out housing, and afterbody then is positioned at housing; Light emitting source then is the LED fluorescent tube.
Owing to adopted the high LED fluorescent tube of brightness as light emitting source, this LED fluorescent tube is different from original common bulb, common bulb has optically focused, can't satisfy the requirement of International Commission on Illumination to Position indication lamp brightness, its brightness that is defined in lamp episphere each point must not be lower than 0.75CD, but the LED lamp luminescence that this product adopts is even in whole episphere brightness, satisfied international standard fully, improved the visual range of life jacket Position indication lamp greatly in all directions, the existing relatively life jacket Position indication lamp of the utility model has been removed lead, directly the water contact switch is located on the housing, has improved reliability, reduced volume.
In order to realize the convenient purpose that detects, be provided with in the housing side and a little touch switch, point touches switch and is connected with the control circuit board test port and is used to test light emitting source and battery integrity, this switch also has another function in addition, when the drowning people be rescued dried up after, can press this switch and close the Position indication lamp power supply, reduce power consumption; Point touches switch and can adopt the water proof rubber button, has improved sealing property.
Above-mentioned battery adopts lithium cell, and the international standard of Position indication lamp is that stream time must not be lower than 8 hours, and the utility model has been owing to adopted lithium cell, and its running time has surpassed 40 hours.
Stud with eye-splice at housing bottom, be convenient to any part that it is inserted in life jacket.
For the life jacket Position indication lamp still can be worked when dried up in the short time, in control circuit board, be provided with time delay circuit, can guarantee that light emitting source still can be worked a period of time after the water contact switch breaks away from the water surface.
