The difference from the previous embodiment is that in the present embodiment, the user needs to push the second lighting device 200 to change the position of the second lighting device 200, and the position change of the second lighting device 200 is supported by the knuckle bearing, the lifting mechanism, and the swivel bearing, which provides higher reliability.

Of course, in other embodiments, the first adjusting component may be a joint bearing, the second adjusting component may be a linear motor, the third adjusting component may be a rotary motor, and the adjustment of the lighting direction, the lighting position, and the lighting angle of the second lighting device 200 relative to the first lighting device 100 may also be realized through the joint bearing, the linear motor, and the rotary motor, and the specific settings of the adjusting components may be changed according to the design requirements of the adjusting device 300.

The first lighting device 100 is disposed on the support frame 410 by means of the rotational connection, which facilitates the adjustment of the lighting direction of the first lighting device 100 by means of the rotational connection.

Further, the support frame 410 is U-shaped, and the support frame 410 is provided with a fixing hole 411, so that the support frame 410 can be fixed on the mounting surface through the fixing hole 411, thereby completing the mounting of the lamp of the embodiment. Specifically, the support frame 410 is formed by stamping an A3 steel plate and is used for fixing the lamp on site.

In an embodiment, referring to fig. 5 to 8, the first illumination device 100 includes a first housing 110, a first light source assembly 120 and a first transparent element 130, the first housing 110 and the first transparent element 130 are hermetically connected and enclose to form a first light source cavity, the first light source assembly 120 is disposed in the first light source cavity, and the first light source assembly 120 can emit light and emit light through the first transparent element 130 for illumination.

The second illumination device 200 includes a second housing 210, a second light source assembly 220 and a second transparent member 230, the second housing 210 is hermetically connected to the second transparent member 230 and encloses to form a second light source cavity, the second light source assembly 220 is disposed in the second light source cavity, and the second light source assembly 220 can emit light and emit light through the second transparent member 230 for illumination.

Specifically, the first lighting device 100 further includes a first sealing ring 140, the first transparent member 130 is hermetically connected to the first housing 110 through the first sealing ring 140, the second device further includes a second sealing ring 240, and the second transparent member 230 is hermetically connected to the second housing 210 through the second sealing ring 240.

Further, the first transparent member 130 is a lens formed by injection molding of an optical PC material, and is used for optical light distribution of a lamp. The second transparent member 230 is a lens injection molded from an optical grade PC material, and serves as a luminaire for flood lighting.

Further, the first light source assembly 120 includes an LED light source and an aluminum substrate, and the second light source assembly 220 includes an LED light source and an aluminum substrate, and has a light emitting function of the lamp.

In an embodiment, the first housing 110 includes a first side for mounting the first transparent member 130 and a second side facing away from the first transparent member 130, and the second lighting device 200 is disposed on the second side.

Since the illumination direction of the first illumination device 100 is the opposite direction of the first transparent member 130, and the second illumination device 200 is disposed on the second side away from the second transparent member 230, the illumination direction of the second illumination device 200 can be opposite to or at an angle with respect to the photographing direction of the first illumination device 100, and the illumination direction of the second illumination device 200 is not the same as the illumination direction of the first illumination device 100.

Further, the second transparent member 230 is disposed on a side of the second casing 210 facing away from the first transparent member 130.

It can be understood that the first illumination device 100 is mainly used for illuminating the lower illumination region, and the second illumination region is mainly used for illuminating the upper illumination region, and since the area of the lower illumination region is larger than that of the upper illumination region, the illumination power of the first light source assembly 120 can be set to be larger than that of the second light source assembly 220, so as to save power consumption and ensure illumination effect.

In an embodiment, the luminaire further includes a driving device 500, and the driving device 500 is disposed on the second side and spaced apart from the second lighting device 200. The input end of the driving device 500 is connected to the mains and is used for supplying power to the first light source assembly 120, the second light source assembly 220 and the adjusting device 300.

Because the first lighting device 100 and the second lighting device 200 can emit heat during lighting operation, in order to ensure the heat dissipation effect of the lamp, the first lighting device 100, the second lighting device 200 and the driving device 500 are arranged separately, and the first casing 110, the second casing 210 and the driving casing of the driving device 500 are used for respectively dissipating heat, so that the heat dissipation efficiency of the lamp can be improved, and the phenomenon that large heat generated by the first light source assembly 120 and the second light source assembly 220 is transferred to the driving device 500, thereby influencing the service life of the driving device 500 is avoided, and further the market competitiveness of the lamp is improved.

Further, the second lighting device 200 is provided with a plurality of groups, and the plurality of groups of second lighting devices 200 can provide more lighting adjustment conditions, so as to better expand the lighting range and achieve better lighting effect.

It can be understood that the heat dissipation of the first illumination device 100 can be accelerated by the heat dissipation sheet 111, and since the power of the first illumination device 100 is higher and the heat generated by the first light source assembly 120 is more, the heat dissipation sheets 111 are uniformly distributed on one side of the first casing 110 away from the first transparent member 130, so that the arrangement of the first casing 110 can meet the heat dissipation requirement of the high-power LED.

In an embodiment, the first housing 110 is provided with a first mounting post 113, the first mounting post 113 is provided with a first mounting hole 114, and the mounting member can penetrate through the second transparent member 230 and the second housing 210 and be connected and fixed with the first mounting hole 114 to fix the second lighting device 200 on the first lighting device 100.

It can be understood that, when the lighting direction, the lighting position and the lighting angle of the second lighting device 200 need to be adjusted, the mounting member needs to be detached to enable the second lighting device 200 to be in a free state relative to the first lighting device 100, which is an operating state of the lamp in the embodiment, when the second lighting device 200 is fixed to the first lighting device 100.

Further, a second mounting post 115 is disposed on the first housing 110, a second mounting hole 116 is disposed on the second mounting post 115, and the mounting member can penetrate through the mounting plate of the driving device 500 and is connected and fixed with the second mounting hole 116 to fix the driving device 500 on the first lighting device 100.

Further, a through hole 117 is further disposed on the first casing 110, and a wiring pipeline 430 is further disposed on the lamp, wherein one end of the wiring pipeline 430 is electrically connected to the first light source assembly 120 through the through hole 117, and the other end is electrically connected to the driving device 500.

Further, the first housing 110 is further provided with a mounting groove 118, and the adjusting device 300 is mounted in the mounting groove 118.

Specifically, the first housing 110 and the second housing 210 are die-cast from the ADC12 material.
