Description

A kind of LED lighting device

technical field

The utility model relates to an LED lighting device.

Background technique

Generally, LEDs (light-emitting diodes: hereinafter referred to as LEDs) are mainly used in display devices. At present, the application range of LEDs has a tendency to expand to lighting equipment or devices. As a cold light source, LED lights have the characteristics of low energy consumption and easy use. According to these characteristics, the use or application of LED can be diversified, such as widely used in large-screen electronic billboards, traffic lights and other lamps, as well as household lighting, decoration and other fields, such as LED lighting lamps, household decorative lamps such as Christmas tree decoration lights etc. When the traditional LED is used as a point light source, the connection wire is directly drawn from the housing, and no fixing measures are used between the connection wire and the housing, resulting in the appearance of the traditional lamp is not delicate, and the connection wire is easy to be removed from the circuit board during use. Pull off, and the existing LED lighting device has a large volume and limited application places, which greatly limits its scope of use.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides an LED lighting device with exquisite appearance, simple structure and small volume, which can prevent the connection wire from being pulled off the circuit board during use.

The technical scheme that the utility model solves its technical problem adopts is:

An LED light-emitting device, including a circuit board, on which a light-emitting device is installed, and the circuit board is connected to a control system circuit, and is characterized in that it also includes a bottom case, and a transparent cover or a translucent cover or a milky white cover is installed on the bottom case , the circuit board is installed in the bottom case, the side of the bottom case is provided with a connection strip, the connection strip is electrically connected to the circuit board, a groove is provided on the inner side wall of the bottom case, and a transparent cover or a translucent cover or The outer wall of the milky white cover is provided with a protrusion that can be engaged in the groove.

As a preferred embodiment of the present invention, the light-emitting device is a single LED lamp bead or a group of RGB three-color LED lamp beads.

As another preferred embodiment of the present invention, the light emitting device is a plurality of LED lamp beads or a plurality of groups of RGB three-color LED lamp beads.

The connecting belt of the utility model can be provided with two, which are relatively arranged on both sides of the bottom shell.

The control system of the utility model can be an external controller, or an IC controller built on a circuit board.

The beneficial effects of the utility model are: the utility model has the characteristics of simple structure, small volume, and exquisite appearance, and it can control each LED lamp bead or each group of RGB three-color LED lamp beads through a control system or a single-chip microcomputer, and can appear A variety of color changes, and centralized control of multiple light-emitting devices through an external control system, which can appear jumping, gradient, chasing, flowing water, colorful color changing and video effects, and can be widely used in LED point light sources, LED horse racing Lamps, LED video color screens, toy watches, replacement products for LED luminous rods commonly used by audiences at concerts, LED luminous belt heads, couple luminous watches and night lights, etc. The grooves are snapped together, which can effectively prevent the connecting wire from being pulled off the circuit board.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a three-dimensional exploded schematic view of an embodiment of the utility model;

FIG. 2 is a schematic perspective view of FIG. 1 .

Detailed ways

Referring to Fig. 1 and Fig. 2, a kind of LED lighting device disclosed by the utility model comprises a bottom shell 1, and a transparent cover or a translucent cover or a milky white cover 2 is installed on the bottom shell 1, a transparent cover or a translucent cover or a milky white cover 2. It can be made of PC, ABS and other materials. The bottom shell 1 can be made into a circle as shown in the figure, or can be made into a square, oval and other shapes.

In order to facilitate the installation and positioning of the transparent cover or translucent cover or milky white cover 2 on the bottom case 1, a groove 3 is provided on the inner side wall of the bottom case 1, and a groove 3 is provided on the outer side wall of the transparent cover or translucent cover or milky white cover 2. There is a protrusion 4 that can be engaged in the groove 3 .

A circuit board 5 is installed in the bottom case 1, and a light-emitting device 6 is installed on the circuit board 5. The light-emitting device 6 can use a single LED lamp bead or a group of RGB (red, green, blue) three-color LED lamp beads. Multiple LED lamp beads or multiple groups of RGB three-color LED lamp beads can be used. And when the utility model is used outdoors, the circuit board 5 and the light-emitting device 6 can be potted and sealed in the bottom case by resin to achieve a waterproof effect.

A control system is connected to the circuit board 5, and the control system may be an external controller or an IC controller (not shown) built in the circuit board.

A connecting strip 7 is arranged on the side of the bottom case 1, and the connecting strip 7 is electrically connected with the circuit board 5. The connecting strip 7 can be set as one or two, and the two connecting strips 7 can be arranged on the side of the bottom case oppositely. sides.

The utility model has the characteristics of simple structure and small volume. It can control each LED lamp bead or each group of RGB three-color LED lamp beads through a control system or a single-chip microcomputer, and various color changes can occur. The control system centrally controls multiple light-emitting devices, which can show jumping, gradual changing, chasing, flowing water, colorful color changing and video effects.

The utility model can be connected with an external high-voltage power supply and widely used as LED point light sources, LED marquees, LED video color screens and night lights. Replacement products for LED light sticks used, LED light belt heads and couple light watches.

The above is only a preferred embodiment of the utility model, and it does not constitute a limitation to the utility model. The utility model also has other structural changes, as long as it achieves the technical effect of the utility model by basically the same means, it should be Belong to the protection scope of the utility model.
