Abstract
The invention relates to a method for prolonging the service lives of infrared lamps. A rectangular aluminum alloy plate is used as an infrared lamp substrate plate, the infrared lamps are arrayed and mounted on the substrate plate in different groups, a shell is made of aluminum alloy, the outer surface of the shell is in the shape of radiating fins, and the infrared lamp substrate plate is mounted in the aluminum alloy shell and closely contacts with the same. Current is limited to supply power for the infrared lamps in a pulse width modulation mode, no matter how current inputted from the outside fluctuates, the current entering the infrared lamps via circuits is quite stable, so that the highest self efficiency of the infrared lamps is guaranteed, and the service lives of the infrared lamps are prolonged. The infrared lamps with long illumination distances and the infrared lamps with short illumination distances are arrayed at intervals in an infrared zooming camera, only a half quantity of the infrared lamps work regardless of long or short illumination distances, heating quantity is reduced, heat dissipation is more uniform, and the service lives of the infrared lamps are prolonged.
Description
Affiliated technical field
The present invention relates to the method that security protection equipment uses, particularly prolong the infrared lamp method in service life.
Background technology
Known infrared lamp in use can distribute great amount of heat energy, and infrared lamp is after startup, and the interior infrared lamp substrate plate of whole working time section has heat and concentrates, and makes the infrared lamp life-span reduce greatly.Because the radiant power of infraluminescence LED is to be directly proportional with electric current; A lot of nonstandard producers use the mode that strengthens electric current to improve radiation response; Though radiation response has improved, yet the big more temperature of electric current is high more, makes that infrared lamp LED itself is overheated to receive very big injury; Even can endanger the components and parts around the infrared lamp, be exactly direct victim like the CCD in the thermal camera.
Summary of the invention
Task of the present invention is to find a kind of infrared lamp method in service life that prolongs, and should improve the radiation response of infrared lamp, does not strengthen the electric current of infrared lamp again, also will make the infrared lamp heat radiation evenly, prolongs the service life of infrared lamp.
The technical solution adopted for the present invention to solve the technical problems is: reduce electric current and do not guaranteeing radiation response through the quantity that increases infrared lamp LED in the excess load; Adopting the pulse width modulation mode current limit is the infrared lamp power supply; The infrared lamp arranged in groups makes heat radiation more even; Far away and the near infrared lamp asynchronous working of irradiation distance of irradiation distance reduces caloric value; Adopt high conductivity raising radiating efficiencys such as aluminium alloy base plate; Increasing the shell area increases the heat-sinking capability of infrared lamp; Thereby promote infrared lamp service life.
Concrete grammar is following:
One, reduces electric current.Use the little infrared lamp of power consumption to replace the infrared lamp of big power consumption, reduced heat dissipation capacity, thereby promote infrared lamp service life.
Two, stable power-supplying.The power supply of employing pulse width modulation mode, no matter how the extraneous electric current of importing fluctuates, and the electric current that enters into infrared lamp through circuit is all highly stable, thereby guarantees the maximum efficient of infrared lamp performance self, prolongs the service life of infrared lamp.
Three, LED lamp arranged in groups makes heat radiation more even, prolongs the service life of infrared lamp.
Four, in the zoom thermal camera, adopt the near infrared lamp of irradiation distance infrared lamp far away and irradiation distance alternately, asynchronous working reduces caloric value, prolongs the service life of infrared lamp.
Five, infrared LED lamp plate and shell use the reasonable materials of heat radiation such as aluminium alloy, make radiating effect better, prolong the service life of infrared lamp.
The invention has the beneficial effects as follows: guarantee that infrared lamp is in good working order all the time, prolong infrared lamp service life.
The specific embodiment
Get the rectangle aluminium alloy plate and make the infrared lamp substrate plate, the infrared lamp arranged in groups is installed on the substrate plate; Aluminium alloy is made shell, and outer surface of outer cover is the heat radiation sheet; The infrared lamp substrate plate is installed in the aluminum alloy casing and closely contact, increases area of dissipation and promotes radiating effect, prolongs the service life of infrared lamp.Adopting the pulse width modulation mode current limit is the infrared lamp power supply, and no matter how the extraneous electric current of importing fluctuates, and the electric current that enters into infrared lamp through circuit is all highly stable, thereby guarantees the maximum efficient of infrared lamp performance self, prolongs the service life of infrared lamp.In the zoom thermal camera, adopt the near infrared lamp of irradiation distance infrared lamp far away and irradiation distance alternately, the irradiation distance distance all has only half infrared lamp in work, reduces caloric value, prolongs the service life of infrared lamp.
Claims (1)
1. prolong the infrared lamp method in service life, should improve the radiation response of infrared lamp, do not strengthen the electric current of infrared lamp again, also will make the infrared lamp heat radiation evenly, prolong the service life of infrared lamp; It is characterized in that using the rectangle aluminium alloy plate to make the infrared lamp substrate plate, the infrared lamp arranged in groups is installed on the substrate plate; Aluminium alloy is made shell, and outer surface of outer cover is the heat radiation sheet; The infrared lamp substrate plate is installed in the aluminum alloy casing and closely contact; Adopting the pulse width modulation mode current limit is the infrared lamp power supply; In the zoom thermal camera, adopt the near infrared lamp of irradiation distance infrared lamp far away and irradiation distance alternately.
