The lighting fixture shown in fig. 1 includes six light source modules. The light source modules 20 are modular and can be arranged in the lamp holder in parallel, and different sizes and powers of the lighting lamps can be formed by arranging different numbers of light source modules. Therefore, the lighting device can be made into a high-power lighting device, and needs to be matched with the high-power supply module 30.

For convenience of description, the light emitting direction side of the light source module is defined as front/front, and the side facing away from the light emitting direction is defined as back/back.

The lamp holder is made of metal/alloy materials with good heat conduction performance, and is made of aluminum materials or aluminum alloys in the embodiment, so that the lamp holder can be used as radiators of the power supply module and the light source module, and the heat dissipation efficiency of the lamp is improved. The lamp holder mainly comprises a front end fixing part 11 and a power supply cavity 12 which are arranged in a spaced and opposite mode, two fixing arms 13 which are arranged in a spaced and opposite mode, and a lamp arm 14 which is rotatably connected to the outer wall of the power supply cavity 12.

The front end fixing portion 11 and the power supply cavity 12 are formed with steps 111 for fixing two end portions of the light source modules 20 arranged side by side and at intervals. The light source modules 20 are arranged at intervals, and natural wind can be used for dissipating heat of the light source modules 20, so that the heat dissipation efficiency is improved.

The lamp arm 14 rotatably fixed on the power supply cavity 12 is used for connecting with a lamp post, so that the angle between the lighting lamp and the lamp arm 14 can be adjusted, and the lamp post is suitable for lamp posts with different heights. Particularly, the lamp arm 14 is led out from one side of the power supply cavity 12, and compared with the scheme that the lamp arms are led out from two ends of the power supply cavity 12, the whole streamline of the lighting lamp is better, and the appearance is more attractive.

Referring to fig. 2 and fig. 3, a card slot 124 is formed on an inner wall of the power cavity 12, and an inlet of the card slot 124 faces an opening of the power cavity (in the embodiment, the opening is located opposite to the fixing arm 13). A fixing plate 123 for fixing the power module 30 is detachably provided in the card slot 124. The fixing plate 123 includes a rectangular base 1231 and a pair of flanges 1232 extending substantially perpendicularly from both sides of the base 1231. The fixing plate 123 is detachably disposed in the power supply chamber 12 in such a manner that the folded edge 1232 is inserted into the inlet of the card slot 124.

More specifically, in the present embodiment, the power supply cavity 12 is an extruded hollow profile, and includes a front plate 121, a rear plate 122 and side plates connecting the front plate and the rear plate, which are oppositely disposed, and the power supply cavity 12 is formed with openings at both ends and sealed by the fixing arm 13. Wherein, a card slot 124 is formed on the opposite side of the front plate 121 and the back plate 122, the extending direction of the card slot 124 is the same as the extrusion direction of the section bar, and the inlet of the card slot 124 is positioned at the opening of the power supply cavity 12. The card slot 124 includes a vertical wall 1211 and an L-shaped folded wall 1212, wherein the folded wall 1212 includes a portion parallel to the vertical wall 1211 and perpendicular to the front plate 121 and a portion extending toward the vertical wall 1211. And a gap larger than or equal to the thickness of the fixing plate is formed between the end of the folding wall 1212 and the vertical wall 1211. Correspondingly, a card slot 124 formed by a vertical wall 1211 and an L-shaped folding wall 1212 is also formed on one surface of the back plate 122 facing the front plate 121. The folded edge 1232 of the fixing plate 123 is matched with the folded wall 1212, so that the folded edge of the fixing plate 123 can be inserted into the clamping groove 124 of the front plate 121 and the rear plate 122, and the folded edge 1232 is buckled with the folded wall 1212, so that the fixing plate 123 can be detachably connected with the front plate 121 and the rear plate 122. The fixing plate 123 is preferably made of metal or metal alloy with good heat conductivity, and in this embodiment, is an aluminum alloy profile, which is convenient and fast to manufacture and has a stable structure.

The power module 30 of the lighting fixture is fastened on the fixing plate 123 through a fastening member, for example, a screw 31, so that the surface of the power module 30 is tightly attached to the fixing plate 123, the heat of the power module 30 can be efficiently conducted to the fixing plate 123, and then conducted to the power cavity 12 through the fixing plate 123, so that the whole lamp holder can be used as a heat dissipation structure of the power module, and the service life of the power module is prolonged.

In addition, the power module 30 may further have heat dissipation fins 32 formed thereon, and heat of the power module 30 may also be dissipated into the power cavity 12 through the heat dissipation fins 32, so that the heat is conducted to the power cavity 12 through air heat, thereby further increasing the heat dissipation efficiency.

Referring to fig. 4 to fig. 7, the light source module 20 mainly includes a heat sink 21, a circuit board 22 having one surface closely attached to the heat sink 21, an optical cover 23, and a fixing member 24. The fixing member 24 is connected with the heat sink 21, so that the optical cover 23 is pressed on the heat sink 21 in a manner that two sides of the optical cover are uniformly stressed, and the circuit board 22 is sealed between the optical cover and the heat sink.

One surface (back surface) of the circuit board 22 is in close contact with the heat sink 21, and the other surface (front surface) is provided with a plurality of light sources 221, which are LED light sources in this embodiment. The circuit board 22 is generally (substantially or approximately, as determined by one of ordinary skill) in the form of a rectangular plate having a width and length that are less than the width and length of the surface of the heat sink 21.

The optical cover 23 is preferably made of a transparent PC material with stable chemical properties. The optical cover 23 serves as a protective cover, a sealing cover, and an optical processing device for the light sources 221, and has a plurality of optical lenses 231 formed thereon in one-to-one correspondence with the light sources 221 on the circuit board to achieve a specific light effect.

The back of the optical cover 23 is formed with an annular groove for fixing the seal ring 26. Thus, water vapor can be prevented from entering the space where the circuit board 22 is located from the gap at the joint of the optical cover 23 and the heat sink, and good waterproof performance can be achieved. A groove or step 232 recessed upward and downward is formed on the long edge of the front surface of the optical cover 23. Preferably, the groove or step 232 extends through one end of the long side and does not extend through the other end of the long side to provide a stop.

The heat sink 21 has a flat fixing surface. Specifically, in this embodiment, the heat sink 21 mainly adopts an aluminum profile with a certain bend, and includes a rectangular first heat transfer plate 211 having a flat fixing surface, two second heat transfer plates 212 integrally extending from two sides (referring to long sides of the first heat transfer plate) of the back surface of the first heat transfer plate 211 or from positions close to the two sides, and a third heat transfer plate 213 connecting ends of the two second heat transfer plates. The first heat transfer plate, the second heat transfer plate, and the third heat transfer plate are each substantially rectangular plate-shaped, and the width of the third heat transfer plate 213 is smaller than the width of the first heat transfer plate 211. Preferably, the third heat transfer plate is parallel to the first heat transfer plate. The outer surface of the second heat transfer plate 212 integrally extends to form a plurality of heat dissipation fins 2121 parallel to the first heat transfer plate 211 or perpendicular to the second heat transfer plate 212. Therefore, on the premise of keeping the inner space of the radiator (being used for wiring and fixing small electronic equipment) larger, the area of the radiating fins is enlarged as much as possible, the radiating effect of the radiator is increased, and the radiator can be adapted to light sources with various powers.

A plurality of second heat dissipation fins 2131 integrally extend from the back surface of the third heat transfer plate 213. The second heat dissipating fins 2131 are preferably perpendicular to the third heat transferring plate 213 and have a low height, so that dirt and dirt are not easily stored, large dirt is not easily caught in the grooves 2132 between the second heat dissipating fins, and accumulated dust is easily washed away by rain.

In addition, the third heat transfer plate 213 has a plurality of through holes 2133 for fixing the bird guard 2134. The bird repelling device 2134 is formed by bending a single metal wire, and includes an elastically deformable fixing portion and two extension arms extending from the fixing portion, and the fixing portion is inserted into the through hole 2133 of the third heat transfer plate 213 to be fixed.

When assembling a plurality of light source modules, all leave the space between a plurality of light source modules 20, above-mentioned space forms the convection current groove between different light source modules 20, allows the air to get into between the second heat transfer plate to can utilize the chimney effect that hot-air rises cold air and supplyes to let the air produce the convection current and directly take away the heat on second heat transfer plate and the third heat transfer plate, thereby improve the radiating effect.

In addition, the length of the second heat transfer plate 212 and the third heat transfer plate 213 is smaller than that of the first heat transfer plate 211, so that when the third heat transfer plate 213 covers part of the first heat transfer plate 211 as seen from the lower surface perpendicular to the first heat transfer plate, the two ends of the first heat transfer plate 211 are in a state of extending out of the heat radiator 21 and can be bridged on the lamp holder, and therefore heat on the heat radiator 21 can be quickly transferred to the lamp holder, and the heat dissipation effect is better. The heat sink can be considered part of the lamp holder.

The first heat transfer plate 211 is further provided with wire holes and fixing holes, so that wires led out of the circuit board 22 can penetrate through the wire holes to the back of the first heat transfer plate 211, and the circuit board 22 can be fastened on the radiator through screws, so that the back of the circuit board is in close contact with the radiator, and the heat conduction effect is ensured.

The back of the first heat transfer plate 211 is also formed with a rib 2112, the rib 2112 is parallel to the long side of the first heat transfer plate, the fixing hole formed on the first heat transfer plate preferably does not penetrate the first heat transfer plate, and the fixing hole is arranged opposite to the rib 2112. Thus, the sealing performance of the light source module can be ensured, and the strength of the radiator can be increased.

The first heat transfer plate 211 has two side walls as long sides, and slide grooves 2114 are formed through the first and second sides. Specifically, the sliding groove 2114 is recessed from a side wall of the first heat transfer plate 211 toward the other side wall opposite thereto, and penetrates the entire side wall in the direction in which the long side extends.

In this embodiment, the optical cover 23 and the heat sink 21 are fixedly connected by the fixing member 24, and the optical cover 23 is not screwed to the heat sink by a fastening member such as a screw. The fixing member 24 is used for connecting with the heat sink 21 to press the optical cover 23 on the heat sink 21 in a manner that two long sides of the optical cover are uniformly stressed. In this embodiment, the fixing member 24 includes two sliders oppositely disposed, each slider includes a strip-shaped substrate and two slide rails extending from two long sides of the substrate, and the two slide rails are oppositely disposed to form a claw shape. One of the slide rails is inserted into the slide groove 2114 on the side wall of the first heat transfer plate 211, and the other slide rail is inserted into the groove or step 232 of the optical cover 23 and pressed against the bottom of the groove or step 232 from top to bottom. Thus, the two long sides of the optical cover are pressed on the heat radiator in a uniformly stressed mode.

The utility model discloses a light source module seals circuit board 23 in the sealed space that optical cover 23 and radiator 21 enclose by setting up at optical cover 23 below groove 2342 inboard waterproof rubber ring 26, setting in the line hole of radiator 21 and the waterproof rubber seat of fixed orifices or other sealing members or sealed glue. Because the optical cover is fixed on the radiator in a way that the long edge of the optical cover is uniformly stressed, the optical cover is not easy to crack even if the optical cover becomes brittle due to being exposed to alkaline environment, and the service performance can be ensured.

In the above embodiment, each heat sink is provided with two circuit boards and two optical covers. It will be appreciated that in other embodiments, only one circuit board and one optical cover may be provided, or one optical cover may be provided to receive two or more circuit boards. Of course, the light source module can be further expanded according to requirements, and only the size of the radiator needs to be adjusted. It will be appreciated that in other variations, three or more sets of circuit boards and optical covers may also be provided on each heat sink.

It is understood that in other embodiments, the optical cover may be fixed to the heat sink by other fixing members, such as screws.

In the above embodiment, the length of the fixing member 24 is substantially the same as the length of the long side of the first heat transfer plate of the heat sink, so that the long side of the optical cover is uniformly stressed. It will be appreciated that in other embodiments, the fixing member may be divided into separate segments instead of a single fixing member. Alternatively, the optical cover and the heat sink may be attached by directly clamping the edges of the optical cover and the first heat transfer plate using a retractable clip.

It will be appreciated that the fasteners such as screws preferably use spacers or washers, and that the surfaces of the spacers or washers that contact the mounting surface preferably conform to the mounting surface, thereby increasing the strength of the connection.

Compared with the first embodiment, the second embodiment is different from the first embodiment mainly in that the power supply cavity occupied by the lamp arm 14' of the lamp holder is smaller in area towards the lamp post and is of a single-arm structure.

In addition, a sighting telescope 15 for determining the irradiation direction of the lighting lamp is fixed on the lamp holder. When the lighting lamp is installed, the installation angle of the lighting lamp can be determined through the sighting telescope 15, and the installation accuracy of the lighting lamp is ensured. The scope 15 may be secured to the power supply cavity 12 adjacent the lamp arm 14' by a barrel fastener.

It is understood that in other embodiments, the sighting telescope may be fixed by forming a mounting hole in the lamp holder 10.

It can be understood that the lamp holder in the first embodiment can also be provided with a sighting telescope.
