Description

Improved structure of the monitor

technical field

The utility model relates to a monitor, in particular to a structure using a light-emitting diode to generate auxiliary light for the monitor.

Background technique

As we all know, the monitor has a very high camera effect, and has been widely used by the police or the public as an auxiliary device to record the surroundings. It has the function of deterring before and checking after the event, and plays an indispensable role in public security and control. Since the dark place is the favorite of Xiaoxiao, it can avoid many eyes, so adding lights to the monitor has become the standard equipment of some products. But at the same time of lighting, there will be a reverse shadow zone, which is often used by people with good intentions, so light-emitting diodes (LEDs), which can project a better camera space, are slowly being applied to lighting. The general light-emitting diode is a cylindrical semi-circular head, which has its basic irradiation range, and when used in a monitor, the light-emitting diode is only arranged in a uniform ring around the lens in the middle, so the general lighting area used for irradiation is Circular, as shown in Figure 11, its shape is similar to the shape of the light beam emitted by a general flashlight.

In the camera lens of the monitor, the photosensitive coupling component standard is 4:3, so the illuminated area of the LED will form a circular 3:3 left and right sides insufficient state, or a 4:4 state with too much upper and lower sides , which are all uneconomical design methods and energy-consuming usage methods. For the 3:3 state, the four corner areas on both sides of the lens will become dead spots, either there is no light, or the light is insufficient, so the image is blurred. However, these areas are often key points. For those who know the law and want to break the law, this is a space that can be used, so there will be insufficient left and right light sources in 3:3. As for the state of 4:4, there is a problem of wasting light sources.

Detailed ways

The utility model provides an improved monitor structure which can not only ensure the illumination intensity on both sides of the lens, but also save the light source. Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figures 1 to 9, it is an improved structure of the monitor of the present invention, which has a ball 1 and a ball seat 2, and the ball 1 is pivotally connected to the ball seat 2. This structure has been used for a long time ( In the utility model, take this as an example, but not limited to this type), it is a basic configuration of a monitor, and the sphere 1 has an upper half shell 11 and a lower half shell 12 ( Please refer to Fig. 8 and Fig. 9, in Fig. 1 to Fig. 3, the sphere 1 is in the non-open state as a whole, while the sphere 1 in Fig. 4 is in the state after the upper half shell 11 is removed, leaving only Its lower half-shell 12 is for viewing), a camera unit 3 is arranged in the sphere 1, and the camera unit 3 has a bottom circuit board 4 (Fig. 7) and a top circuit board 5 (Fig. 6), and the bottom circuit board 4 is provided with a photosensitive A lens element 50 and a lens 51 are arranged on the top circuit board 5 of the coupling element 40; a light circuit board 6 is fixed above the top circuit board 5, and a photoresistor 61 and several light-emitting diodes 62 are arranged on the light circuit board 6; The lens 51 on the board 5 passes through the middle of the light circuit board 6 and is connected to the lens assembly 50; wherein,

The arrangement of the light emitting diodes 62 is an ellipse conforming to the standard of the photocoupler 40 to produce the best and most economical lighting design. Since the standard for coupling photosensitive components is 4:3, the aspect ratio of the ellipse is preferably 4:3. In order to form the ellipse, the arrangement of the light-emitting diodes can be as follows: two rings are arranged concentrically at intervals, and a pair of light-emitting diodes are respectively arranged on the left and right sides of the rings, for example: the number of light-emitting diodes is 24, and in the ring The number of light-emitting diodes in the inner circle can be 9, and the number of light-emitting diodes in the outer circle can be 11, so that the best 4:3 imaging can be formed.

The light emitting diode 62 is an infrared light emitting diode (but not limited thereto), and the infrared light emitting diode is provided for use in a dark place and at night. At this time, a photoresistor 61 can also be arranged on the light circuit board 6 to serve as a medium for starting the light emitting diode 62 .

The lens assembly 50 is provided with a lens holder 53, and the lens 51 is screwed on the lens holder 53, so that the lens 51 can be replaced conveniently. Wherein in Fig. 9, it is to show the lens of fixed type, simultaneously because there is no need to replace the lens, the top plate 13 of the upper half shell 11 of sphere 1 is closed, in contrast among Fig. 1 to Fig. 8, all are the lens that performance can be replaced Therefore, there is a through hole 14 in the middle of the top panel 13 of the half shell 11 on the sphere 1, so that the lens can pass through, and the lens can be directly replaced, such as 3.6mm F1.2 or 6.0mm F1.2, which can produce different The setting effect of focal length; Wherein, in Fig. 1, show to be provided with a lens cover 52, show in Fig. 8, lens 51 is cylindrical, external thread is connected with internal thread of lens holder 53, reaches the effect of easy replacement.
