Abstract
The utility model relates to a selectable auxiliary light source for a camera, which mainly comprises an LED (light-emitting diode) array, a lamp panel, a case, a battery socket and control buttons, wherein the LED array comprises infrared LED lamps and white-light LED lamps which are arranged in an intersection way; the lamp panel is an aluminium-base lamp panel with a high heat-conducting property; and two light sources, namely the infrared LED lamps and the white-light LED lamps, are selected by switching selection circuits. The appearance structure of the selectable auxiliary light source for the camera adopts a dustproof and waterproof design, and thus the selectable auxiliary light source is suitable for being used outdoors; the selectable auxiliary light source has a good heat-conducting property and long service life; and with selection on the infrared LED lamps and the white-light LED lamps, the camera can be ensured to take clear pictures at night, and humanized choices are added on the camera, and therefore, the selectable auxiliary light source is applicable to a wider field compared with similar equipment in the prior art so as to have wide application and promotion values.
Description
Technical field
The utility model relates to video camera secondary light source device, particularly a kind of selective video camera secondary light source.
Background technology
At present, use the demand that the infrared video camera secondary light source that conduct is used always with white LED lamp is realized round-the-clock monitoring in 24 hours in the monitoring technique field.Some ccd image sensor has very wide sensitization spectral range; Its sensitization spectrum not only comprises the visible region; Also extend to region of ultra-red, utilize this characteristic, can not have under the situation of visible illumination at night; With auxiliary infrared light supply illumination ccd image sensor is formed images clearly, but the image that under the situation that infrared lamp is opened, forms is a black and white.And colour TV camera is for ability transmitting color signal; From the output signal of CCD device, isolate turquoise red three kinds of primary video signals; Synthetic then colour TV signal, its sensitization spectrum increases the demand that infrared illuminator can not realize night monitoring only in the visible region; At this moment can increase white led lamps and throw light on as secondary light source, the image that under white led lamps, forms under the situation is colored.
But single secondary light source can not satisfy the inconsistency requirement of different user to image (black and white/colour), and needs to cooperate the kind of video camera to match.Therefore, how to address this problem with regard to the technician that becomes the present technique field the problem that will study and solve.In order to address the above problem, studying novel video camera secondary light source is a feasible approach.
Summary of the invention
The purpose of the utility model is exactly for overcoming the deficiency of prior art, provide a kind of satisfy be used for different user demands, and reduce design proposal to the dependent novel video camera secondary light source of video camera.Design this time is incorporated into on a kind of device with white LED lamp infrared, and two kinds of secondary light sources can be selected according to user's demand.Picture quality is had relatively high expectations and need the place of color display at factories and miness, underground pipeline etc., can select white LED light source through the button on the device; Only need show that when night black white image gets final product, the user selects infrared lamp as secondary light source through the button on the device.Make it can satisfy the needs that use under the night vision condition of different industries like this.
The utility model is to realize through such technical scheme: selective video camera secondary light source, it is characterized in that, and mainly constitute by led array, lamp plate, shell, attaching plug, control knob;
Led array comprises infrared LED lamp and white LED lamp, wherein infrared LED lamp and white light LEDs cross arrangement, and lamp plate 2 adopts the aluminium base lamp plate of high thermal conductivities;
Infrared LED lamp in the led array is connected control switching circuit respectively with white LED lamp, by the break-make in control switching circuit control infrared LED lamp and white LED lamp loop.
The beneficial effect of the utility model is: through switching selecting circuit it is selected to two kinds of light sources; Lamp plate adopts the aluminium base lamp plate of high thermal conductivity, and design dustproof, waterproof that selective video camera secondary light source contour structures adopts is applicable to outdoor; Its good heat conductivity; Equipment life is long, not only guarantees can absorb distinct image night through the selection to infrared lamp and white LED lamp, and has increased the selection of hommization; Therefore existing same category of device suitable application area is more wide, has and uses widely and promotional value.

Embodiment
Understand the utility model for clearer, describe the utility model in detail in conjunction with accompanying drawing and embodiment:
To shown in Figure 5, selective video camera secondary light source mainly is made up of led array 1, lamp plate 2, shell 3, attaching plug 4, control knob 5 like Fig. 1,
Adopt 140 Φ 5mm type LED lamps, LED be square tube core bonding or sintering on lead frame, the positive pole of tube core is an internal lead through spherical contact point and gold wire bonding, and links to each other with a pin, another pin of negative pole and lead frame links to each other.Through switching selecting circuit it is selected to two kinds of light sources.Lamp plate adopts the aluminium base lamp plate of high thermal conductivity, good heat conductivity, and equipment life is long.Design dustproof, waterproof that selective video camera secondary light source contour structures adopts is applicable to outdoor.
Make secondary light source reach request for utilization like this, and good looking appearance cost performance rational in infrastructure is high.Not only guarantee to absorb distinct image night through selection, and increased the selection of hommization infrared lamp and white LED lamp.Therefore existing same category of device suitable application area is more wide, has and uses widely and promotional value.
Selective video camera secondary light source can be used for the place of monitoring in 24 hours round the clock, and the user can independently select according to the specific requirement to display image (colour/black and white).Important technological parameters is following:
Led light source: infrared lamp/white LED lamp
Classification of waterproof: IP65
Operating temperature: 0 ° of C-50 ° C
Delay time: 5-60s
Level angle: 120 °
Depression angle: 86 °
Light source control: can manually select infrared lamp/white LED lamp light source
According to above-mentioned explanation, can realize the scheme of the utility model in conjunction with art technology.
