Abstract
The utility model relates to an infrared illuminator. The utility model comprises a housing, a lens and an infrared luminous tube. The front end of the housing is provided with a protective glass shell. A printed circuit board, a wind guide plate, a power supply of the luminous tube and an electric fan are installed in the housing, and the printed circuit board is provided with the infrared luminous tube and the lens. Ventilating openings are arranged on the housing and the printed circuit board. The device has the advantages of simple structure, favorable ventilation effect, far illumination distance and low cost. The novel infrared illuminator of the utility model has the popularized value.
Description
The utility model relates to a kind of infrared illuminator, for the ccd video camera video camera provides illumination.
At present, form by shell, infraluminescence pipe and printed-wiring board (PWB) for the infrared illuminator that cooperates ccd video camera to carry out video camera in the prior art.Dress printed-wiring board (PWB) in the shell, dress infraluminescence pipe on the printed-wiring board (PWB), the shell circumscripted power line, do not adorn lens in this infrared illuminator, so the optically focused poor performance, illuminating effect is not good, the shell circumscripted power line, use also inconvenience, and the setting of ventilating in the luminaire, aeration structure is very undesirable.
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of infrared illuminator that lens, luminotron power supply and fan wind deflector are housed is provided, and this luminaire both can independently use, and can combine use with ccd video camera again.
The utility model to achieve these goals; propose following technical scheme: this infrared illuminator comprises housing, lens and infraluminescence pipe; housing front end dress cover glass; anterior dress printed-wiring board (PWB) in the housing; dress infraluminescence pipe on the printed-wiring board (PWB); the head of infraluminescence pipe is contained in the center pore of lens opening bottom of support, adorns lens on the lens opening of support.Support also can be made up of the lens board and the luminous tube sheet of band lens opening, lens board is contained on the openend of luminous tube sheet cavity, luminous tube sheet bottom has the center pore relative with the lens opening center, and printed-wiring board (PWB) one end and housing sidewall front end are opened air vent, printed wire back dress
The type wind deflector, housing back, wind deflector back dress luminotron power supply and fan, perhaps at the printed-wiring board (PWB) two ends and housing back one end open the air port, the other dress of housing back ventilating opening
Dress luminotron power supply on the housing back in the type wind deflector, wind deflector.
The utility model is simple in structure, with the luminous angle of lens compression luminotron, has improved illumination distances.The luminotron power supply is housed in the device, uses easily, the fan in the device has improved aeration structure effectively, improved its serviceable life and luminescence efficiency greatly, and can independently use, can be used in combination with ccd video camera again, cheap, be easy to promote the use of.
Concrete structure of the present utility model is provided by accompanying drawing 1～3.
Fig. 1 is an infrared illuminator one-piece construction synoptic diagram.
Fig. 2 is the structural representation of support.
Fig. 3 is an infrared illuminator one-piece construction synoptic diagram.
Primary structure is among the figure: housing 1, cover glass 2, support 3, lens 4, infraluminescence pipe 5, ventilating opening 6, printed-wiring board (PWB) 7, wind deflector 8, luminotron power supply 9, fan 10, cavity 11, lens board 12, luminous tube sheet 13, pore 14, lens opening 15.
Below in conjunction with accompanying drawing the utility model is described in detail.
This infrared illuminator as shown in Figure 1; comprise housing 1, lens 4 and infraluminescence pipe 5; housing front end dress cover glass 2; anterior dress printed-wiring board (PWB) 7 in the housing; several infraluminescence pipes of dress on the printed-wiring board (PWB), the head of infraluminescence pipe is contained in the center pore 14 of lens opening 15 bottoms of support 3, adorns lens on the lens opening of support; the sidewall front end of printed-wiring board (PWB) one end and housing has ventilating opening 6, printed-wiring board (PWB) back dress
Type wind deflector 8; housing back, wind deflector back dress luminotron power supply 9 and fan 10; this structure makes the air-flow of enclosure interior form two passages; a passage is formed by cover glass and printed-wiring board (PWB); another is formed by printed-wiring board (PWB) and wind deflector, and the ventilating opening on the wiring board converges the air-flow in two passages and leads to fan.The support that infraluminescence pipe and lens are housed in this infrared illuminator also can be made up of the lens board 12 and the luminous tube sheet 13 of band lens opening 15, as shown in Figure 2, lens board is contained on cavity 11 openends of luminous tube sheet, luminous tube sheet bottom has the center pore relative with the lens opening center, as shown in Figure 3: this device also can have ventilating opening at the back of printed-wiring board (PWB) two ends and housing one end, the other dress of housing back ventilating opening
The type wind deflector; dress luminotron power supply on the housing back in the wind deflector; this structure also is divided into two passages by printed wire with the enclosure interior air-flow; a passage is formed by wiring board and wind deflector; another passage is formed by cover glass and wiring board; ventilating opening with the same end of ventilating opening on the wiring board separates air-flow, and the ventilating opening of the other end converges air-flow.Its ventilation of the structure of the above this device and illuminating effect have an improvement than conventional art is big, and direct dress luminotron power supply in the housing uses very convenient.
