In this embodiment, since the adjusting assembly 120 can drive at least a portion of the illumination assembly 110 to rotate, so that the first direction is changed, the user can adjust the illumination direction of the illumination assembly 110 to the designated illumination area by adjusting the illumination direction of the illumination assembly 110, thereby further improving the illumination effect of the illumination area.

Since the adjusting assembly 120 only drives at least a portion of the lighting assembly 110 to rotate, the driving scheme is simple and reliable.

The lamp of the embodiment is applied to the roadway, the lower environment area of the roadway can be illuminated through the second illuminating device 200, and the upper environment area of the roadway can be illuminated through the first illuminating device 100, so that bidirectional illumination of the roadway is realized.

In the present embodiment, the adjusting component 120 is connected to the first light source component 112 and is used for driving the first light source component 112 to rotate, so that the first direction is changed. Through the rotational position of adjusting first light source subassembly 112, the luminous direction of adjustable first light source subassembly 112, and then change the light angle through first transparent 113 to realize the adjustment of lighting assembly 110's direction of illumination, in order to realize first lighting device 100's multi-angle illumination, because adjustment subassembly 120 only drives first light source subassembly 112 rotatory, the drive scheme is comparatively simple, and the reliability is high. Of course, in other embodiments, the adjusting assembly 120 may also be connected to the lighting assembly 110 and configured to drive the lighting assembly 110 to rotate, so as to change the first direction, and also realize the change of the lighting direction of the lighting assembly 110, and the driving scheme is also simpler and has higher reliability.

Preferably, the first transparent member 113 is at least partially arc-shaped, so that the first transparent member 113 can be a flood transparent member, so that the lighting assembly 110 can be flood-illuminated, and further, the multi-angle flood-illumination of the first lighting device 100 can be realized by adjusting the lighting direction of the lighting assembly 110. The curvature of the first transparent member 113 may be R11.6 mm.

Further, in the present embodiment, the adjusting assembly 120 includes a rotating button 121, a transmission assembly 122 and a supporting member 123, the supporting member 123 is accommodated in the first light source cavity 116 and is used for bearing the first light source assembly 112, the rotating button 121 is disposed outside the first light source cavity 116, the rotating button 121 is in transmission connection with the supporting member 123 through the transmission assembly 122, and pushing the rotating button 121 to rotate can cause the transmission assembly 122 to transmit a rotating motion to the supporting member 123, so that the supporting member 123 drives the first light source assembly 112 to rotate.

The user can push the rotation knob 121 to rotate, so as to adjust the rotation position of the first light source assembly 112, and thus adjust the illumination direction of the illumination assembly 110.

Preferably, the transmission assembly 122 includes a first gear 1221, a second gear 1222, and a transmission shaft 1223, the first gear 1221 and the second gear 1222 are disposed in the first light source cavity 116, the first gear 1221 is fixed to the support 123, the second gear 1222 is engaged with the first gear 1221, the transmission shaft 1223 penetrates a wall surface of the first housing 111, and connects the rotation knob 121 and the second gear 1222.

The driving assembly 122 is a gear set, and the stability and reliability of the rotation adjustment of the supporting member 123 can be ensured by a gear transmission manner, so as to ensure the stability and reliability of the adjustment of the rotation position of the first light source assembly 112.

Specifically, first light source cavity 116 is a cylindrical cavity, and support member 123 is semi-cylindrical and can rotate in first light source cavity 116 to securely fit support member 123 in first light source cavity 116.

It can be understood that, since the first light source cavity 116 is formed by enclosing the first housing 111 and the first transparent member 113, the light emitted from the first light source assembly 112 can only exit through the first transparent member 113, so as to realize the illumination of the illumination assembly 110.

Furthermore, when the adjusting assembly 120 drives the first light source assembly 112 to rotate and face the first transparent member 113, the intensity of the emergent light of the illuminating assembly 110 is higher; when the driving assembly drives the first light source assembly 112 to rotate to form an angle with the first transparent member 113, the intensity of the emergent light of the illumination assembly 110 is reduced, for example, the first light source assembly 112 may form an included angle of 20 ° with the horizontal plane; when the driving assembly drives the first light source assembly 112 to rotate to face away from the first transparent member 113 and face the first casing 111, the light emitted from the first light source assembly 112 is shielded by the first casing 111, and the illumination assembly 110 cannot realize illumination.

Therefore, the adjustment of the rotational position of the first light source assembly 112 by the adjustment assembly 120 can adjust not only the illumination direction of the illumination assembly 110, but also the illumination intensity of the illumination assembly 110.

In an embodiment, the light fixture further includes a support frame 310 and a connector 320, and the second lighting device 200 is rotatably connected to the support frame 310 through the connector 320. The second lighting device 200 is disposed on the supporting frame 310 by means of the rotation connection, which facilitates the adjustment of the lighting direction of the second lighting device 200 by the rotation connection.

Further, the support frame 310 is U-shaped, and the support frame 310 is provided with a fixing hole through which the support frame 310 can be fixed on the mounting surface, thereby completing the mounting of the lamp of the present embodiment. Specifically, the supporting frame 310 is formed by punching an A3 steel plate and is used for fixing the lamp on site.

Further, since the first lighting device 100 is disposed on the second lighting device 200, the lighting direction of the second lighting device 200 can be adjusted by rotating the connection, so that not only the lighting direction of the second lighting device 200 can be changed, but also the lighting direction of the first lighting device 100 can be changed, thereby increasing the variety of the lighting angle adjustment of the second lighting device 200.

During specific application, the angle of the second lighting device 200 relative to the supporting frame 310 can be adjusted to complete the adjustment of the lighting area below by the second lighting device 200, and then the lighting direction of the lighting assembly 110 is adjusted by the adjusting assembly 120, so as to complete the multi-angle floodlight adjustment of the first lighting device 100 above.

In an embodiment, the second illumination device 200 includes a second housing 210, a second light source assembly and a second transparent member 220, the second housing 210 and the second transparent member 220 are hermetically connected and enclose a second light source cavity, the second light source assembly is disposed in the second light source cavity, and the second light source assembly can emit light and emit the light through the second transparent member 220 for illumination.

Specifically, the first lighting device 100 further includes a first sealing ring 117, the first transparent member 113 is connected to the first housing 111 through the first sealing ring 117 in a sealing manner, the second device further includes a second sealing ring, and the second transparent member 220 is connected to the second housing 210 through the second sealing ring in a sealing manner.

The first housing 111 is provided with a first mounting post 114, the first mounting post 114 is provided with a first mounting hole 115, and the mounting member 1141 can penetrate through the first transparent member 113 and is fixedly connected with the first mounting hole 115, so as to fixedly connect the first transparent member 113 and the first housing 111.

Further, the first transparent member 113 is a lens injection-molded by optical-grade PC material, and plays a role in floodlighting of the lamp.

In the present embodiment, the second housing 210 includes a first side for mounting the second transparent member 220 and a second side facing away from the second transparent member 220, and the first lighting device 100 is disposed on the second side.

Since the illumination direction of the second illumination device 200 is the opposite direction of the second transparent member 220, and the first illumination device 100 is disposed on the second side away from the second transparent member 220, the illumination direction of the first illumination device 100 can be opposite to or at an angle with respect to the photographing direction of the second illumination device 200, and the illumination direction of the first illumination device 100 is not the same as the illumination direction of the second illumination device 200.

Further, the first transparent member 113 is disposed on a side of the first casing 111 facing away from the second transparent member 220.

It is understood that the second illumination device 200 is mainly used for illuminating the lower illumination region, the first 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 second light source module can be set to be larger than that of the first light source module 112, so as to save power consumption and ensure illumination effect.

In an embodiment, the luminaire further includes a driving device 400, and the driving device 400 is disposed on the second side and spaced apart from the first lighting device 100. The input end of the driving device 400 is connected to the mains and is used for supplying power to the first light source assembly 112 and the second light source assembly.

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 400 are arranged separately, and the first casing 111, the second casing 210 and the driving casing of the driving device 400 are used for respectively dissipating heat, so that the heat dissipation efficiency of the lamp can be improved, and the phenomenon that the larger heat generated by the first light source assembly 112 and the second light source assembly is transferred to the driving device 400, thereby influencing the service life of the driving device 400 is avoided, and further the market competitiveness of the lamp is improved.

Further, the first illumination device 100 is provided with a plurality of groups, and the plurality of groups of first illumination devices 100 can provide more illumination adjustment conditions, so as to better expand the illumination range and achieve better illumination effect.

Preferably, the first lighting devices 100 are provided in two groups, and are respectively disposed at both sides of the driving device 400. The two groups of first lighting devices 100 are symmetrically arranged relative to the driving device 400, so that the lighting range above the second lighting device 200 can be better expanded, and the lighting effect is better.

Specifically, referring to fig. 12, fig. 12 shows a schematic diagram of the light-emitting intensity of each direction of the lamp when the first lighting device 100 is adjusted to a certain angle, and the light-emitting intensity of each direction of the lamp of the first lighting device 100 can be changed by adjusting the rotation angle of the first lighting device 100.

Referring to the light emitting direction of fig. 4, in fig. 12, a curve i represents the light emitting intensity of the first lighting device 100 in the left and right directions, and a curve ii represents the light emitting intensity of the first lighting device 100 in the front and back directions.

Of course, in other embodiments, there may be four, six or more sets of the first lighting devices 100, and when there are four sets of the first lighting devices 100, there may be four sets of the second lighting devices 200 circumferentially distributed around the driving device 400.

In an embodiment, the second side is provided with a plurality of heat dissipation fins, which can accelerate the heat dissipation of the second illumination device 200, and since the power of the second illumination device 200 is higher and the heat generated by the second light source module is more, the heat dissipation fins are uniformly distributed on the side of the second casing 210 away from the second transparent component 220, so that the second casing 210 can meet the heat dissipation requirement of the high-power LED.

Specifically, the first housing 111 and the second housing 210 are die-cast from the ADC12 material. The first casing 111 is not only used for arranging the first light source assembly 112, but also used for dissipating heat generated by the operation of the first light source assembly 112 through the first casing 111, and a heat sink may be arranged on one side of the first casing 111 close to the second casing 210.
