a lighting device

Technical field:

The utility model relates to the technical field of light-emitting products, in particular to a light-emitting device with a simple structure and a decorative effect.

Background technique:

In addition to being used for lighting, the current lighting equipment is also used as a decorative device by people to beautify the environment and heighten the atmosphere. With the development of electronic technology and LED (Light Emitting Diode) technology, current lighting devices can produce various lighting effects, such as color transformation and so on. However, the structure of these light-emitting devices is relatively complicated at present, and it is difficult to realize artificial control of color changes.

Utility model content:

The technical problem to be solved by the utility model is to further improve the current product and provide a light-emitting device with simple structure and capable of manually controlling the change of light-emitting color.

In order to solve the above technical problems, the utility model adopts the following technical solution: the light emitting device includes: a base, a battery cavity formed on the base, and a circuit board fixed on the base, wherein the circuit board is provided with The illuminant is composed of a plurality of lamp bodies with different luminous colors, and a power control switch and a color-fixing switch are arranged at the bottom of the base.

The illuminant is an LED with three luminous colors of red, green and blue. These three LEDs are used as the three primary colors of color transformation, and through the light and dark combination of different color LEDs, different luminous colors are formed.

The power control switch and the color fixing switch are arranged at the bottom of the base. The power switch controls the opening or closing of the power supply; and the color change is realized by controlling the opening or closing of different colors through the fixed color switch.

The bottom of the base is also provided with a pull ring, the two ends of the pull ring are hinged to the bottom of the base, and a groove for accommodating the pull ring is formed on the bottom surface of the base. The pull ring can facilitate the base to be pulled out from the lampshade, so as to facilitate the disassembly of the product.

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is a perspective view of the utility model;

Fig. 2 is a three-dimensional exploded view of the utility model;

Fig. 3 is the top view of the utility model after removing the circuit board;

Fig. 4 is a bottom view of the utility model.

Detailed ways:

See Figures 1-4, the utility model includes: a base 1, a battery cavity 2 formed on the base 1, a circuit board 3 fixed on the base 1, wherein a luminous body 4 is arranged on the circuit board 3, In this embodiment, the illuminant 4 is an LED with three luminous colors of red, green, and blue. These three LEDs are used as three primary colors for color transformation, and different luminous colors are formed by combining bright and dark LEDs of different colors. Of course, other LED light-emitting lamps of different colors or different numbers can also be used, which can also achieve the purpose of color transformation. Alternatively, an individual RGB (red, green, blue) LED containing three colors can be used, that is, an individual LED can generate at least three different monochromatic lights. In addition, a power control switch 5 and a color fixing switch 6 are arranged at the bottom of the base 1 . The power switch 5 controls the opening or closing of the power supply; and the color-fixing switch 6 controls the opening or closing of different colors to realize the transformation of the color of the illuminant 4 .

The battery cavity 2 is molded on the base 1. The battery cavity 2 is three cylindrical cavities combined in the shape of "pin". The end cover of the battery cavity 2 is set on the base 1. bottom surface. Three batteries can be placed in the battery cavity 2 to provide power for the utility model. The cover plate 21 of the battery cavity 2 is arranged on the bottom surface of the base 1 .

The circuit board 3 is located at the top of the battery cavity 2 , and is clamped and fixed with the posts on the fixed surface of the battery cavity 2 . The battery in the battery cavity 2, the illuminant 4, the power control switch 5 and the color-fixing switch 6 are all electrically connected on the circuit board 3.

When using the utility model, after the power control switch 5 was connected, the whole circuit started to work, and the LED lamps of three colors just began to be combined and changed constantly. After the luminous body 4 appears a certain color that meets the user's needs, press the fixed color switch 6, and at this time, the signal on the circuit board 3 sends an abort signal, and the three LEDs no longer change colors, and the color of the luminous body 4 remains stable until it is turned on again. Press the color-fixing switch 6, and the luminous body 4 begins to continue the process of cyclically changing color. In order to protect the illuminant 4 , a cover body 41 can be set outside the illuminant 4 .

When the utility model is in use, a light-transmitting lampshade can be set on its outer cover, and the lampshade is fixed by the positioning clip 12 on the base 2 . That is, four positioning clips 12 distributed in a circle are molded on the base 1 . The lampshade is covered outside the positioning clamping plate 12 and forms a ferrule fit with the positioning clamping plate 12 . In order to facilitate pulling out the utility model from the lampshade, a pull ring 7 is provided at the bottom of the base 1 through which the user can pull the utility model out from the lampshade. Both ends of the pull ring 7 are hinged to the bottom of the base 1, and a groove 11 that can accommodate the pull ring 7 is formed on the bottom surface of the base 1, so that the pull ring 7 can be rotated to the concave position when the pull ring 7 is not in use. in slot 11.

To sum up, the utility model not only has a simple structure, but also can realize the color transformation of the artificially controlled light, which can bring more fun and decorative effect to users.

Of course, the above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the scope of implementation of the present utility model, so all equivalent changes made according to the shape, structure and principle of the present utility model should be covered by this utility model. within the scope of protection of utility models.
