Embodiment Construction

[0016] In order to understand the present invention more clearly, describe the present invention in detail in conjunction with accompanying drawing and embodiment:

[0017] like Figure 1 to Figure 5 As shown, the combined auxiliary light source for the camera is mainly composed of an LED array 1, a light board 2, a housing 3, a power plug 4, and a control button 5.

[0018] The LED array 1 includes an infrared LED lamp 11 and a white LED lamp 12, wherein the infrared LED lamp 11 and the white LED lamp 12 are arranged crosswise, and the infrared LED lamp 11 and the white LED lamp 12 in the LED array are respectively connected to a switching control circuit and controlled by the switching control circuit Infrared LED lamp 11 and white LED lamp 12 loop on and off.

[0019] 140 pieces of Φ5mm LED lights are used. The LED is a square tube core bonded or sintered on the lead frame. The positive electrode of the tube core is bonded to the gold wire through a spherica...

Abstract

The invention relates to a combined auxiliary light source for a camera. The combined auxiliary light source mainly comprises a light emitting diode (LED) array, a lamp panel, a shell, a power supply plug and a control button; the LED array comprises infrared LED lamps and white LED lamps, wherein the infrared LED lamps and the white LED lamps are crossed; and the lamp panel is an aluminum-based lamp panel with high heat conducting property. Two light sources are selected by switching a selection circuit; the combined auxiliary light source for the camera can be applied outdoors due to dustproof and waterproof design of the external structure, and has good heat conducting property and long service life; and by selecting the infrared lamps and the white LED lamps, clear images can be shot at night, and humanized selection is increased, so that the combined auxiliary light source has broader application field and wide application and popularization value compared with conventional similar equipment.

Description

technical field [0001] The invention relates to a camera auxiliary light source device, in particular to a combined auxiliary light source for a camera. Background technique [0002] At present, in the field of monitoring technology, infrared and white LED lights are used as auxiliary light sources for cameras commonly used to achieve 24-hour monitoring needs. Some CCD image sensors have a very wide photosensitive spectrum range, and their photosensitive spectrum not only includes the visible light region, but also extends to the infrared region. Using this feature, the CCD image can also be illuminated by an auxiliary infrared light source at night when there is no visible light illumination. The sensor images are sharp, but with the IR lights turned on the resulting image is black and white. In order to transmit color signals, color cameras separate green, blue, and red primary color video signals from the output signal of the CCD device, and then synthesize color ...
