Detailed Description

The lighting device of the present invention will be described in detail with reference to the following embodiments and accompanying drawings.

For convenience of description, the light emitting direction side of the lighting fixture is defined as front/front, and the side facing away from the light emitting direction is defined as back/back. That is, the light fixture emits light toward the front of the light fixture.

Referring to fig. 1, in an embodiment, the lighting device of the present invention mainly includes a lamp housing 10 and two light source modules 20 assembled on the lamp housing 10. The lamp housing 10 is made of a metal material with good heat dissipation performance by integral molding, and the two light source modules are fixed on the lamp housing 10 at intervals and in parallel. A portion (bottom portion) of the lamp housing 10 located at the rear side of the light source modules 20 is formed with an opening 11 facing the space between the two light source modules 20. Thus, in addition to directly dissipating heat from the light source module 20 by directly conducting heat to the lamp shade 10, the heat itself dissipating to the surrounding air may cause air to flow, and the existence of the opening 11 allows the hot air to escape from the opening 11, while the cold air above the lamp enters from the opening 11, and convection air may be generated to dissipate heat more quickly. Particularly, the light-transmitting cover is not arranged in front of the light source module 20, so that air convection is smoother, and the heat dissipation effect is better.

More specifically, the globe 10 is flat and substantially square in bottom, and the sidewall transitioning with the bottom arc encloses all three sides of the bottom, with only one side serving as the first end 12 of the globe for connection to the light pole. In this embodiment, the inner cavity of the lamp housing 10 is divided into a light source chamber 14 and a power supply chamber 15 by an annular wall 13 extending substantially vertically from the bottom of the lamp housing. The cavity surrounded by the annular wall 13 is a power supply cavity 15, one side of the annular wall 13 is a first end 12, and the other side is a light source cavity 14. So that the power supply cavity 15 is located between the first end 12 and the light source cavity 14. The power supply cavity 15 is closed by a power supply cavity cover 16, and a gap between the two is sealed by a sealing rubber ring, so that the power supply module 60 inside the power supply cavity works in a dry environment. The lamp housing 10 and the power supply chamber cover 16 together form a lamp holder of the lighting fixture.

An opening 11 is formed at the bottom of the light source cavity 14. The light source cavity 14 is integrally formed with oppositely disposed light source fixing posts 141, the light source module 20 is mounted on the light source fixing posts 141, a part of the generated heat is directly conducted to the lamp shade 10 through the light source fixing posts 141, and the other part is conducted to the surrounding air. Because the front side opening of the light source cavity 14 is not shielded, and the bottom is provided with the opening 11, when the light source module works, convection air which passes through the front part of the light source cavity 14 and the rear bottom opening is extremely easy to generate, and the heat dissipation of the light source module is accelerated.

Referring to fig. 1 and 2, a lamp arm fixing structure is formed on the lamp housing 10 at the first end 12. The arm fixing structure includes two solid columns 121 integrally extending from the bottom of the lamp housing. The posts 121 are disposed adjacent to the sidewalls of the housing 10 such that a space is formed between the two posts into which the light pole can extend. The end of the column 121 is an arc surface, and a screw hole 122 and a plurality of parallel raised strips 123 are formed. The protrusion 123 protrudes from the arc-shaped mounting surface of the column and is disposed around the screw hole 122.

In addition, the solid column 121 is connected to the side wall of the power supply cavity, i.e. the annular wall 13, through a connecting wall 124 extending from the bottom of the lamp housing, so that when the lamp housing 10 is connected to a self-contained or external lamp arm, the bottom plate of the lamp housing 10, the column 121 and the annular wall 13 together bear the weight of the whole lighting lamp, and are strong and durable.

The first end 12 of the lamp housing further integrally extends from the bottom of the lamp housing to form two fixed arm fixing posts 125, the two fixed arm fixing posts 125 are located inside the connecting wall 124, and the side walls of the two fixed arm fixing posts 125 are integrally connected with the connecting wall 124 or the column 121. The space between the two fixed arm fixing posts 125 allows a cylindrical external arm to be inserted. The two fixed arm fixing posts 125 are used to fix a cylindrical external arm to the first end 12 by the fixed arm fixing fitting 40 shown in fig. 3, and the connection angle between the external arm and the lighting fixture is not adjustable. The fixing member 40 for fixing the arm is substantially in a long shape, fixing holes are formed near both ends, and the fixing member 40 can be fixed to the fixing arm fixing post 125 by screws 41, so that the outer circumference of the external arm is banded together with the bottom of the lamp housing and the fixing arm fixing post 125. When the fixing fitting 40 is configured, a lighting fixture as shown in fig. 7 can be assembled.

When the lighting fixture needs to be connected with an external lamp post in an angle-adjustable manner, the lighting fixture with the lamp post as shown in fig. 6 needs to be assembled by using the lamp arm 50 as shown in fig. 4 and 5 as an accessory. The arm 50 is used for connecting with an external light pole, and mainly includes a hollow cylindrical rod 51 and an arc-shaped mounting member 52 connected to one end of the rod 51. The rod body 51 is provided with a screw hole for fixing with an external lamp pole, and the rod body is provided with a bulge 512 for increasing the connection strength with the external lamp pole. The mounting member 52 is an arc-shaped metal plate, and two long holes 521 are formed at positions of the mounting member 52 opposite to the two screw holes 122, and a long strip-shaped wire hole 523 communicated with the inside of the rod body 51 is further formed. A plurality of parallel convex strips 522 corresponding to the convex strips 123 of the lampshade are formed on the periphery of the long hole 521. The lamp arm 50 and the lamp housing 10 are fastened together by means of screws 524 screwed into the screw holes 122 through the elongated holes 521. Meanwhile, when the screw 524 is located at different positions of the elongated hole 521, the specific positions at which the protruding strips of the lamp arm 50 and the lampshade 10 are engaged with each other are different, resulting in different connection angles between the lamp arm and the lampshade. That is, the position of the screw 524 in the elongated hole 521 is controlled to adjust the connection angle between the arm 50 and the housing 10, thereby controlling the connection angle between the lamp post and the lighting fixture. It will be appreciated that the slot 521 runs perpendicular to the axis of rotation of the arm 50 relative to the housing 10, and the ribs 123,522 should run parallel to the axis of rotation of the arm relative to the housing. The effect of the

convex strips

123 and 522 is the same as that of the gear teeth, the connection stability between the lamp arm 50 and the lamp shade 10 is increased by mutually clamping and meshing, and meanwhile, the adjustment of the connection angle and the precision of the angle adjustment are facilitated. The protrusion 123 protrudes from the top surface of the column 121, increasing the strength of the top surface, and it can be understood that in other embodiments, the protrusion 123 may be flush with or lower than the top surface of the column 121, as long as the protrusion can be engaged with the lamp arm and the lamp cover.

In addition, in order to achieve the sealing of the power supply chamber, the power supply line entering the power supply chamber should be sealed at the wire hole and other parts. The connection of the power supply cavity cover 16 and the power supply cavity 15 may be by means of a convenient opening of the power supply cavity cover 16, for example a snap-fit connection with a screw on one side and a hook-fit connecting rod on the other side.

In this embodiment, the first end of the lamp housing 10 is close to the power supply cavity 15, and it can be understood that in other embodiments, when the power supply cavity is not needed, or the power supply cavity is not located at the first end of the lamp housing, the structural arrangement of the lamp arm fixing structure is not affected. As long as the first end of lamp shade sets up two at least solid cylinders, the cylinder end is formed with the screw, is formed with many parallel arrangement's sand grip at the periphery of screw or one side of at least screw, can realize with lamp arm interconnect, angularly adjustable function. Because the screw hole is deep into the solid column, a large-size screw can be used for connecting the lamp arm and the lampshade, and the strength of the lamp arm fixing structure can be improved. If the solid column can be connected with the side wall of the lampshade, the strength of the fixing structure can be further increased.

In the above embodiment, only two light source modules are provided, and correspondingly, only one opening 11 is provided. It can be understood that the utility model discloses the accessible sets up the light source module of different quantity and can constitute the illumination lamps and lanterns of different size of a dimension and different power. Correspondingly, the number of the openings can be in one-to-one correspondence with the number of the gaps between the adjacent light source modules, and the number of the openings can also be less than the number of the gaps between the light source modules.

While the invention has been described in conjunction with the specific embodiments set forth above, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications, and variations that fall within the spirit and scope of the appended claims.
