Embodiment
The utility model provides a kind of flashlamp, and its compact conformation, easy for installation can reduce light pollution.
Fig. 1 is the structural representation of the flashlamp of the utility model.Fig. 2 is the cut-open view of the flashlamp of the utility model.As depicted in figs. 1 and 2; The flashlamp of the utility model comprises: reflector 101; Be arranged at the flashlamp source 102 at reflector center; Be installed in the light grid 103 at the rim of a cup place of reflector 101, for flashlamp source 102 provides the wiring board 104 of control signal with the flash of light energy, and with each component packages housing 105 therein.
Wherein, as shown in Figure 1, the front panel of housing 105 has the opening 106 of the light ejaculation that supplies flashlamp source 102, and the position of this opening 106 is corresponding with the rim of a cup position of reflector 101.
This flashlamp comprises that further the wiring board 104 in housing 105 leads to the connecting line 107 beyond the housing 105, and connecting line 107 generally includes the power lead 201 and the control line 202 that is used to provide control signal that is used to provide the flash of light energy.
Can find out that from Fig. 1 and Fig. 2 the structural design of the flashlamp of the utility model is compact, all parts all are encapsulated in the housing 105; Therefore need not to be equipped with in addition the accessory bag; Only need connecting line 107 be connected and can accomplish on-the-spot the installation, it is more convenient that equipment is installed, and it is easier to safeguard.
In the utility model, housing 105 can adopt metal material such as aluminium alloy to process, and needs through the Mould Machining manufacturing.Reflector 101 is made of plastics, and needs through the Mould Machining manufacturing.And flashlamp source 102, light grid 103 etc. all can use existing finished product to assemble according to actual needs.
In addition; Owing to installed light grid 103 at the rim of a cup place of reflector 101; This light grid can make the light outgoing under unobstructed situation perpendicular to the light grid surface; Acutangulate light different according to the arrangement of the network of light grid surface and thickness then in the angular range with the light grid surface, with receiving stopping in various degree, thereby make light in working range, stronger luminance brightness can be provided through the outgoing of light grid; Then light is invisible outside working range, thereby solves the problem of light pollution.
The flashlamp of the utility model provides a kind of preferred embodiment of smooth grid.As shown in Figure 1, this light grid 103 comprises the regular hexagon grid of a plurality of adjacent arrangements, the regular hexagon grid adjacency that each regular hexagon grid all is adjacent through an one of which sidewall.
Preferably; The height of each regular hexagon grid is 7mm, and thickness is 15mm, and the positive light transmission of the cellular smooth grid of arranging by this way of hexagon is the strongest; Its marginal portion is visible with light in the scope of 20 ° of vertical light grid surfaces; And light is invisible in the scope beyond greater than 20 °, and promptly the light shooting angle α of this light grid is 40 °, thereby vehicle picture shot in effective range of guaranteeing to satisfy in the track is clear.
Further; For the cleanliness factor of the working environment that guarantees enclosure interior, as shown in Figure 2, printing opacity baffle plate 108 that is used to seal this opening 106 of opening 106 places installing of housing 105; It promptly can guarantee the closure of housing 105, can not stop the outgoing of light again.Preferably, this printing opacity baffle plate 108 is processed by tempered glass, and the surface is difficult for getting wet, and makes flashlamp can adapt to complex environment.
Generally, flashlamp source 102 provides the flash of light energy through discharging and recharging of electric capacity, and therefore, the wiring board 104 of the flashlamp of the utility model is provided with four electric capacity that the flash of light energy is provided for flashlamp.Further; In order to realize the light intensity regulating of flashlamp; The wiring board 104 of the flashlamp of the utility model is provided with I/O (I/O) port that is used to receive from the control signal of the video camera that is used with flashlamp, with the charging and discharging state according to four electric capacity of this control signal control.
Preferably, this control signal is divided into high-level control signal and low level control signal, so that flashlamp can two kinds of varying photonic intensities work.Usually, under the condition that irradiate light intensity is bigger by day, the light in the vehicle window can't satisfy the condition of under normal flash of light situation, seeing face characteristic clearly, and the intensity of illumination that therefore need strengthen flashlamp suppresses the interference of extraneous light.Then this moment, video camera shines state work to make flashlamp source 102 through discharging and recharging of four electric capacity with high-strength light through I/O port input high level control signal.And at night since extraneous light a little less than, under normal flash of light situation, can satisfy the condition of seeing face characteristic and car plate clearly.Then this moment, video camera shines state work to make flashlamp source 102 through discharging and recharging of two electric capacity in four electric capacity with LOIHT through I/O port input low level control signal.Like this; The flashlamp of the utility model can receive the input/output end port from the high-level control signal and the low level control signal of video camera through being provided with; Realized to make video camera can improve the quality of photographic images according to the light intensity of extraneous illumination condition real-time regulated flashlamp according to the purpose of control signal through the charging and discharging state realization control flashlamp light intensity of control capacitance; And can save the energy, reduce power consumption.
Can be known that by above embodiment the flash lamp design of the utility model is reasonable in design, outward appearance is small and exquisite complete, and all accessories all are encapsulated in the housing, only needs that connecting line is connected the scene of can accomplishing and installs, and maintains easily.
Further,, make this flashlamp only stronger luminance brightness is provided in working range, and invisible, solved the problem of light pollution at the working range UV light owing to increased the light grid in the flashlamp of the utility model.
In addition; The flashlamp of the utility model has the input/output end port that can receive high-level control signal and low level control signal; Can realize the purpose of control flashlamp light intensity according to control signal through the charging and discharging state of control capacitance; Thereby realized the light intensity of real-time regulated flashlamp, improved the quality of photographic images.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the scope of the utility model protection.
