The specific embodiment

Fig. 1

Shown in Fig. 1 instance, by the perimeter of embodiment of the invention illumination.Environment is shown as warehouse 101, and wherein first group of security camera 102,103,104 is fixed on first wall.Second group of

security camera

106 and 107. are provided on second wall 105

Lighting device in the embodiment of the invention is fixed on the position 108,109,110,111 and 112 of first wall.Lighting device 108 to 112 has illuminated the zone 113 that vehicle is parked, although possible, when lamp 108 to 112 and video camera 102 to 104 were mounted, this was not being known the most at the beginning.These lamps 108 to 112 are with video camera 102 to 104 co-operation, and monitoring is parked in the vehicle in zone 113, and require video camera 102 to 104 collection audio-visual-materials and reach the color of vehicle can be recognized.Therefore, in such cases, evidence shows which vehicle at rest is in zone 113 clearly.

Lighting device 114,115 and 116 is with

video camera

106 and 107 co-operation on second wall.Vehicle is through door 117 entering warehouses, but the individual should clear and definite definite vehicle attribute, and with normal use warehouse, so videograph is not extremely important.Accordingly, the illumination of type can be arranged and is used for illuminator 114 to 116 in addition, with respect to illuminator 108 to 112.

In addition, lighting device is provided at 118 and 119, effectively on door 120, illumination is provided.

Illumination

118 and 119 is not set for the purpose of ensuring public security, and does not have camera arrangements in these illuminations place, but illumination is to provide for purpose of safety.Therefore the color of light is not extremely important, considers that enough illuminations are provided at door 120 zones.

Can notice, can behind certain hour, change that therefore, for example in security is used, preferably adopt infrared illumination, it is visible to video camera, pollutes but can not produce unnecessary light to the requirement of illuminator shown in Figure 1.In application, the light that is provided is used for security purpose the most basically, and radiative actual color is not too important, considers enough bright of illumination.Therefore, emphasis should place on the efficient of illumination.Similarly, be important zone in the color of light, for example when the color of registration of vehicle, must adopt white light to guarantee that colouring information can be by accurate recording.The present invention is convenient to the transposing of individual LED equipment in the whole device, therefore allows such luminous lighting is taked to change, and relative is quick and convenient, to allow at the space lighting requirement of considering under the condition of replacing.

Embodiments of the invention can be arranged in such interior zone that can get into the people, and are as shown in Figure 2.Passing through through whole building is provided shown in the corridor 201.In this example, to public opening, and other times will receive strict restriction to this building at one day part-time.In normal entry time, illumination provides through conventional illuminator, possibly be installed in the suspended ceilings 202.Yet when during entrance area is by strict control, it is unnecessary that traditional lighting will be considered to, but the disappearance of any illumination will cause the security relevant issues.Therefore, in this embodiment, corridor 201 has been mounted security surveillance camera 203, although it does not need a large amount of light to operate, needs light to a certain degree.Therefore environment has benefited from incorporating of security light, and it will comprise video camera 203 with video recording apparatus one logical work.

Fig. 3 A

One embodiment of the present of invention are that wall is installed, and have therefore made things convenient for installation, maintenance and entering.In installation process, installing rack 301 firm being installed on the wall 302.

Fig. 3 B

After firmly installing rack 302 arrived wall 302, lighting device 303 was disposed on the frame 201, and its location can be adjusted like this, and lighting device can be changed as a whole.
