Description

{A camera module including LED lamp with improved brightness}

The present invention relates to a camera module used in a parking lot, and in particular, an LED lamp with improved brightness that minimizes the number of LEDs on the one hand and maximizes the brightness of the area to be photographed by the camera on the other hand. It relates to a camera module that does

LED lamps (Light Emitting Diode Lamps) are installed in various places in the underground parking lot (hereinafter referred to as the parking lot) so that the driver can visually check the parking space and the parking lot road to move to the parking space. Recently, for post-processing of accidents occurring in parking lots and for unmanned management of parking lots, additional cameras were installed on lamps that were used only to illuminate the inside of parking lots, and the lamps illuminate the shooting area and the additional cameras were installed. A camera module that takes a picture of the area using the camera module is being commercialized.

Cameras with improved performance due to the development of optical technology can obtain high-quality images even in dark places. The downside is that it's not effective.

Recently, as the area of the parking lot is increasing and the number of unmanned parking lots is increasing, it is expected that the number of camera modules to be installed in the parking lot increases. There is an increasing demand for the performance to remain the same or to be improved while not increasing the purchase cost.

Hereinafter, the present invention will be described in detail by describing preferred embodiments of the present invention with reference to the accompanying drawings. Like reference numerals in each figure indicate like elements.

1 is a plan view and a side view of a camera module including an LED lamp with improved brightness according to the present invention.

The upper part of FIG. 1 is a plan view of a camera module 100 (hereinafter, referred to as a camera module) including an LED lamp with improved brightness, and a side view of the camera module is shown in the lower part.

Referring to FIG. 1 , it can be seen that the camera module 100 according to the present invention is coupled to the support 10 fixed to the ceiling of the parking lot.

2 is a side cross-sectional view and a rear view of a camera module according to the present invention.

A side cross-sectional view of the camera module 100 is shown in the upper part of FIG. 2 , and a rear view of the camera module 100 is shown in the lower part.

Referring to FIG. 2 , the camera module according to the present invention can be implemented with a coupling socket 110 , a shade 120 , a diffusion cover 130 , a holder 140 , a PCB 150 and an LED lamp 160 . it can be seen that

The coupling socket 110 is mounted on the socket insertion groove 11 installed on one surface of the support 10, and is electrically connected to an electrical connection means (not shown) installed on the inner surface of the socket insertion groove 11 to connect the camera The operating power of the module 100 is obtained. Since an external power source (not shown) supplies power to an electrical connection means installed on the inner surface of the socket insertion groove 11 is conventional, it will not be described in detail here.

The shade 120 covers the upper portion of the camera module 100 to protect the components installed therein, and the coupling socket 110 is coupled to the central portion. Referring to the embodiment shown in the upper part of Figure 1 and the lower part of Figure 2, the shade 120 is preferably implemented in a circular shape. Although the coupling socket 110 and the socket insertion groove 11 are electrically connected, the coupling socket 110 is electrically insulated from the shade 120 .

The diffusion cover 130 effectively disperses the light emitted from the plurality of LEDs constituting the LED lamp 160 installed therein to the lower portion of the camera module 100 while being coupled with the lower portion of the shade 120, so that the shooting area or Maximize the visibility of the area to be illuminated. By variously controlling the material and curved surface of the diffusion cover 130 , the light emitted from the LED may be evenly spread over a desired area of a wide range or may be focused on a specific area of a narrow range.
