(13) As shown in FIGS. 3 and 4, the light-concentrating structure 13 is mounted inside the shell 11 and is disposed between the light-emitting module 12 and the light-passing cover 111. The light-concentrating structure 13 comprises at least one condenser lens 131 corresponding to the at least one light-emitting unit 221, concentrating the light, and projecting the light toward the light-passing cover 111.

(14) As shown in FIGS. 2 to 4, the at least one pivotable connecting assembly 20 is connected between two adjacent light assemblies 10. To be more specific, one pivotable connecting assembly 20 is connected between two light assemblies 10. The at least one pivotable connecting assembly 20 comprises a joint seat 21, a middle pivotable rod 22 and a joint rod 23. The joint seat 21 is mounted at one of the two adjacent light assemblies 10 and has a joint hole 211. The middle pivotable rod 22 comprises a pivotable connecting end 221 and a pivot hole 222. The pivotable connecting end 221 is pivotably mounted at the joint hole 211 of the joint seat 21. The joint rod 23 is mounted at the other one of the two adjacent light assemblies 10 and is pivotably mounted at the pivot hole 222 of the middle pivotable rod 22. The two adjacent light assemblies 10 are connected to each other through the at least one pivotable connecting assembly 20, thereby being pivotable relative to each other.

(15) As shown in FIGS. 5 to 9, the project light device can project lights toward different directions simultaneously. The project light device comprises the multiple light assemblies 10, and two adjacent said light assemblies 10 are connected through the at least one pivotable connecting assembly 20 and so can pivot relative to each other. Therefore, after setting up the project light device, projecting directions and angles of the multiple light assemblies 10 can be adjusted respectively. The multiple light assemblies 10 can project lights toward different directions without being respectively adjusted with positions and setting angles, effectively increasing convenience in use.

(16) Additionally, as shown in FIGS. 1 and 5, the project light device comprises a ground post 30 pivotably connected to one of the multiple light assemblies 10 and connected to the shell 11 of said light assembly 10. The project light device can be easily and steadily mounted on the ground through the ground post 30, thereby facilitating ease in installation of the project light device.

(17) Preferably, as shown in FIGS. 2 to 4, the pivotable connecting end 221 of the middle pivotable rod 22 of the at least one pivotable connecting assembly 20 extends along a first direction D1. The pivot hole 222 of the middle pivotable rod 22 extends along a second direction D2. The first direction D1 and the second direction D2 are non-parallel. In this embodiment, the first direction D1 and the second direction D2 are perpendicular.

(18) As shown in FIGS. 5 and 6, in this embodiment, an amount of the multiple light assemblies 10 is three, and an amount of the at least one pivotable connecting assembly 20 is two. The ground post 30 is connected to the middle one of the three light assemblies 10. The joint seats 21 of the two pivotable connecting assemblies 20 are respectively mounted at two opposite sides of the middle light assembly 10. The three light assemblies 10 are arranged in a line.

(19) In addition, as shown in FIGS. 6 and 7, when pivoting the multiple light assemblies 10 axially along the first direction D1, the joint rod 23 and the middle pivotable rod 22 of the at least one pivotable connecting assembly 20 are pivoted relative to the joint seat 21. So, an arrangement of the multiple light assemblies 10 is adjusted. Besides, as shown in FIG. 8, when pivoting the multiple light assemblies 10 axially along the second direction D2, the joint rod 23 of the at least one pivotable connecting assembly 20 is pivoted relative to the middle pivotable rod 22. So, projecting directions and angles of the multiple light assemblies 10 are adjusted. Additionally, as shown in FIG. 9, when pivoting the multiple light assemblies 10 axially along the first direction D1 and the second direction D2, the arrangement, the projecting directions and angles of the multiple light assemblies 10 are adjusted simultaneously. Therefore, the multiple light assemblies 10 can project lights toward different directions, or the multiple light assemblies 10 can project light toward the same spot to increase brightness.

(20) In addition, as shown in FIGS. 2 to 4, the at least one pivotable connecting assembly 20 comprises multiple screws 24. The pivotable connecting end 221 is mounted at one of two opposite ends of the joint hole 211 of the joint seat 21. One of the multiple screws 24 extends into the other end of the joint hole 211 of the joint seat 21 and is screwed into the pivotable connecting end 221. The joint rod 23 is mounted at one of two opposite ends of the pivot hole 222 of the middle pivotable rod 22. One of the multiple screws 24 extends into the other end of the pivot hole 222 of the middle pivotable rod 22 and is screwed into the joint rod 23. Adjusting the multiple screws 24 can fix the projecting directions and angles of the multiple light assemblies 10.

(21) Preferably, as shown in FIGS. 1 and 5, the ground post 30 comprises a universal connecting mechanism 31 and three supporting sticks 32. The three supporting sticks 32 are connected to one end of the universal connecting mechanism 31, and another end of the universal connecting mechanism 31 is connected to the shell 11 of one of the multiple light assemblies 10. The three supporting sticks 32 are foldable. In addition, setting the project light device on the ground through the three supporting sticks 32 increases stability. The three supporting sticks 32 can be folded, hence facilitating ease in storage. Besides, the universal connecting mechanism 31 is connected between the light assemblies 10 and the three supporting sticks 32. So, angles of the multiple light assemblies 10 relative to the ground on which the ground post 30 is set can be adjusted, further enlarging adjustable scopes of projecting directions and angles of the multiple light assemblies 10.

(22) Furthermore, as shown in FIGS. 3 and 4, the light emitted from the at least one light-emitting unit 221 of the light-emitting module 12 of each one of the multiple light assemblies 10 is concentrated through the at least one condenser lens 131 corresponding to the at least one light-emitting unit 221 before being projected toward the light-passing cover 111. Therefore, intensity of the lights projected from the multiple light assemblies 10 is enhanced, increasing decorative ability and saving energy.

(23) Additionally, as shown in FIGS. 3 and 4, the light-concentrating structure 13 comprises an installing board 132. The at least one condenser lens 131 is mounted on the installing board 132.

(24) In addition, as shown in FIGS. 2 and 4, the shell 11 comprises a heat-dissipation-hole portion 112 having multiple heat-dissipation holes through the shell 11. The heat-dissipation-hole portion 112 dissipates heat generated by the light-emitting module 12 away from the shell 11, thereby increasing heat-dissipation ability. Preferably, the light-passing cover 111 and the heat-dissipation-hole portion 112 are disposed at two opposite sides of the shell 11.

(25) Furthermore, as shown in FIGS. 3 and 4, each one of the multiple light assemblies 10 comprises a heat-dissipation board 14 mounted inside the shell 11 and connected to the light-emitting module 12. The heat-dissipation board dissipates heat generated by the light-emitting module 12, thereby increasing heat-dissipation ability.

(26) Additionally, in another configuration of the light-passing cover 111, the light-passing cover 111 further comprises a figure. The figure is set on the light-passing cover 111, so when the light emitted by the light-emitting module passes through the light-passing cover 111, a projecting pattern corresponding to the figure is projected to the environmental objects toward which the project light device projects light, thereby providing a decorative effect.

(27) Besides, in this embodiment, as shown in FIGS. 3 and 4, an amount of the at least one light-emitting unit 221 of the light-emitting module 12 is multiple. Each one of the multiple light-emitting units 221 emits lights in multiple colors. Therefore, the environmental objects projected by the multiple light assemblies 10 have different colors to provide decorative effect.

(28) Furthermore, the light-emitting module 12 comprises a controlling unit electrically connected to the at least one light-emitting unit 221. The controlling unit controls the at least one light-emitting unit 221 to turn on or off, controls time periods during which the at least one light-emitting unit 221 turns on or off, and controls the at least one light-emitting unit 221 to emit lights in different colors. The controlling unit of the light-emitting module 12 of each one of the multiple light assemblies 10 controls the at least one light-emitting unit 221 of the light-emitting module 12 to emit lights in different colors and controls the at least one light-emitting unit 221 to turn on or off, so that the project light device provides decorative lighting effect according to needs.

(29) To sum up, the multiple light assemblies 10 of the project light device project lights toward different directions simultaneously without being respectively set with positions and setting angles, effectively increasing convenience in use. The light-concentrating structure 13 concentrates the lights emitted from the light-emitting module 12 to enhance light intensity and save power. Besides, the multiple light assemblies 10 can project lights in different colors to provide decorative effect.
