Abstract
The utility model relates to an infrared lighting device which is used together with a camera in the dark environment, which is characterized in that at least a fixed through hole is arranged on a casing of a support bracket; a plastic optical beam expander lens is fixed at the front end of each through hole; an infrared semiconductor laser is arranged at the rear end of each through hole; the pins of each infrared semiconductor laser are all connected with the power supply; a heat radiating embossed groove is arranged on the outer surface of the casing of the support bracket. The utility model has the advantages that the lighting distance is far, the power consumption is low and the heat dissipation is favorable.
Description
The utility model relates to the work of a kind of cooperation video camera, is used for the infrared illuminator at dark surrounds.
At present, general rectangle or the rhombus matrix formed by a plurality of infrarede emitting diodes of the infrared illuminator of Cai Yonging, because the infrarede emitting diode output power is little, even it is very big that rectangle of being made up of a plurality of infrarede emitting diodes or rhombus matrix are made, still can not observe remote target clearly, in addition, forming the infrarede emitting diode of matrix works simultaneously, strengthened power consumption, make himself and surrounding enviroment temperature raise rapidly, thereby shortened the life-span of infrarede emitting diode.
It is far away that the purpose of this utility model provides a kind of irradiation distance, low in energy consumption, is beneficial to the infrared illuminator of heat radiation.
The purpose of this utility model is achieved in that this infrared illuminator comprises bracing frame housing, light path shaping beam expanding lens sheet, infrared semiconductor laser, it is characterized in that: have more than one fixed via on the bracing frame housing at least, the front end of each through hole is fixed a light path shaping beam expanding lens sheet, an infrared semiconductor laser is fixed in the rear end of each through hole, the pin of each infrared semiconductor laser all is connected with power supply, and the appearance of bracing frame housing has the heat radiation tongue and groove.
Because the laser beam that adopts the such scheme infrared semiconductor laser to launch is carried out shaping, is expanded bundle by light path shaping beam expanding lens sheet, increased irradiated area, the infrared semiconductor laser that is adopted, make irradiation distance farther, reduced simultaneously power consumption again, the tongue and groove of bracing frame shell appearance has increased its surface area, helps heat radiation, and self is heating radiator.
Further specify below in conjunction with accompanying drawing team the utility model,
Fig. 1 is the infrared illuminator structural representation
As shown in Figure 1, the utility model infrared illuminator comprises bracing frame housing 1, the through hole 3 on the bracing frame housing, the apparent tongue and groove 2 of bracing frame housing, light path shaping beam expanding lens sheet 5, infrared semiconductor laser 4.
On bracing frame housing 1, has more than one fixed via 3 at least, the front end of each through hole is fixed a light path shaping beam expanding lens sheet 5, an infrared semiconductor laser 4 is fixed in the rear end of each through hole, the pin of each infrared semiconductor laser all is connected with power supply, and the appearance of bracing frame housing has heat radiation tongue and groove 2.
Owing to adopt such scheme, this infrared illuminator has the processing of being easy to, and easy for installation, volume is little, the longevity The characteristics such as life is long.
