Preferably, the housing is made of plastic.

Preferably, the aluminum-based circuit board is hermetically connected in the shell through an insert injection molding process.

Preferably, a power supply cavity is further formed in the shell, a power supply module is arranged in the power supply cavity, the power supply module is electrically connected with the aluminum-based circuit board, the back face of the power supply cavity is sealed, and a cover plate is arranged on an opening in the front face of the power supply cavity.

More preferably, the cover plate is integrally connected to the lens.

Compared with the prior art, the utility model has the following beneficial effects.

The utility model abandons the traditional method of sealing the circuit board in the lamp shell, adopts an innovative structure of embedding the aluminum-based circuit board in the shell frame, directly exposes the back of the aluminum-based circuit board in the air, realizes good heat dissipation effect, does not need to be provided with a radiator, leads the appearance of the lamp to be thinner, more beautiful and can reduce the cost.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and are not intended to limit the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1-3, the outdoor lamp of the present invention includes a housing 1 and an aluminum-based circuit board 2, and the aluminum-based circuit board 2 is provided with LED lamp beads 4. The shell 1 is provided with a hollowed-out embedding frame 11 (see fig. 4), the shape and size of the embedding frame 11 are matched with those of the aluminum-based circuit board 2, so that the aluminum-based circuit board 2 is just embedded in the embedding frame 11, the peripheral edge of the aluminum-based circuit board 2 is hermetically connected with the inner edge of the embedding frame 11, and the aluminum-based circuit board 2 is hermetically connected with the shell 1. In one embodiment of the present invention, the housing 1 is made of plastic, the aluminum-based circuit board 2 is hermetically connected in the housing 1 by an insert injection molding process, and the edge of the aluminum-based circuit board 2 is wrapped by the plastic of the housing 1 (see fig. 5 and 6), that is, in the process of injection molding the housing 1, the aluminum-based circuit board 2 is injection molded inside the housing 1 as an insert, so that the reliability of the hermetic connection between the aluminum-based circuit board 2 and the housing 1 can be ensured.

As shown in fig. 1 and 5, a lens 3 covers the front surface of the casing 1 (i.e. the bottom surface of fig. 1 and 5), and the LED lamp bead 4 is attached to the front surface of the aluminum-based circuit board 2 and faces the lens 3. The back surface (i.e. the top surface in fig. 1 and 5) of the aluminum-based circuit board 2 is not covered with a cover, so that the aluminum substrate on the back surface of the aluminum-based circuit board 2 is directly exposed in the air (as shown in fig. 2 and 7).

As shown in fig. 3 and 6, a power supply cavity 12 is further arranged in the housing 1, a power supply module 5 is arranged in the power supply cavity 12, and the power supply module 5 is electrically connected with the aluminum-based circuit board 2 to provide a driving power supply for the LED lamp bead 4. The back side of the power supply chamber 12 is closed and the front side of the power supply chamber 12 is provided with an opening and the opening is closed by a cover plate 3 ', the lens 3 and the cover plate 3' not being shown in fig. 3. In a preferred embodiment of the utility model, the cover 3 'is integrally connected to the lens 3, i.e. an extension of the lens 3 constitutes the cover 3' for covering the opening of the power supply chamber 12.

In the structure of the utility model, the heat generated by the LED lamp beads 4 can be directly dissipated into the air through the back surface of the aluminum-based circuit board 2 without an additional radiator, so that the lamp is lighter, thinner and more beautiful in appearance, and the cost can be reduced. The power module 5 is arranged in an independent power cavity 12 of the shell 1, and the heating of the power module 5 and the heating of the LED lamp beads 4 cannot affect each other.
