Fig. 1 shows a lighting device 10 according to a first embodiment of the present application for illuminating a work area. The lighting device 10 is a portable stand light that is portable. When a user needs to work outdoors, the user may carry the lighting device 10 outdoors to provide lighting needs. The lighting device 10 of the present embodiment is different from a desk lamp, which is usually placed on a desk for illumination, but the lighting device 10 in fig. 1 is usually standing on the ground for illumination of a work area when in use, so the lighting device 10 may also be referred to as a ground standing lamp.

Regarding the energy source, the lighting device 10 of fig. 1 may be powered by the battery pack 30, so that the lighting device 10 may be powered by the battery pack 30 even when a user works outdoors and there is no commercial power around, thereby facilitating use. Thus, the lighting device 10 is different from the existing lamp which can be supplied only by alternating current, and the lighting device 10 may also be referred to as a direct current lighting device 10. Of course, it will be appreciated that the lighting device 10 is not limited to being powered using only the battery pack 30. If the lighting device 10 is powered by either the battery pack 30 or the ac power, the lighting device 10 may also be referred to as a dc standing lamp.

As shown in fig. 1 to 6, the lighting device 10 includes a standing mode and a storage mode, and it is understood that in the standing mode, the lighting device 10 is in an operating state, and a user can use the lighting device 10 to illuminate a working area. In the storage mode, the user can conveniently carry the lighting device 10.

In the present embodiment, the lighting device 10 includes: a support mechanism 11, a lighting mechanism 12 and a connecting mechanism 13. The support mechanism 11 includes a base 11a and support legs 11b connected to the base 11a. The base 11a includes a battery mounting portion 111, and the battery mounting portion 111 is used to connect and hold the battery pack 30. The lighting mechanism 12 comprises a base 121 for emitting light. The connection mechanism 13 is for supporting the base 121. The connection mechanism 13 is connected to the support mechanism 11.

As shown in fig. 1 and 3 to 5, when the lighting device 10 is in the standing mode, the lighting device 10 is configured to be supported by the placement surface 10a constituted by the support mechanism 11. It will be appreciated that the lighting device 10 is used in a standing mode in which the lighting device 10 is placed on a floor or work surface, with the support means 11 constituting a placement surface 10a which is in contact with the floor or work surface. By providing support, it is meant that the lighting device 10 can be stably placed on a floor or work surface without resorting to external forces.

The connection mechanism 13 includes: telescoping assembly 131. The telescoping assembly 131 is configured with a central axis 101. When the lighting device 10 is in the standing mode, the telescopic assembly 131 is extended and retracted in the direction of the central axis 101 to drive the lighting mechanism 12 away from and towards the support mechanism 11. The telescopic assembly 131 further comprises at least a first position and a second position, wherein, as shown in fig. 3 and 4, when the telescopic assembly 131 is in the first position, an included angle α between the central axis 101 and the placement surface 10a is greater than or equal to 0 ° and less than or equal to 30 °. In the present embodiment, in the first position, the limit position is such that the angle between the central axis 101 and the placement surface 10a is approximately 0 °, that is, the central axis 101 is disposed substantially parallel to the placement surface 10a. In this embodiment, the included angle α between the central axis 101 and the placement surface 10a is greater than or equal to 0 ° and less than or equal to 30 ° and any position point(s) within the included angle range falls within the scope of the first position of the present application. It should be noted that in actual adjustment, the central axis is not perfectly parallel to the placement surface 10a due to tolerances or manufacturing errors, and measurement related errors, and thus parallelism or substantial parallelism should be considered as disclosing a range defined by the absolute values of the two endpoints. Parallel or substantially parallel arrangement may refer to the central axis 101 being at an angle of 0 deg. plus or minus a percentage (e.g., 1%,5%,10% or more) to the placement surface 10a. In the first position, the projection of the lamp cap on the placement surface is positioned outside the projection of the supporting mechanism on the placement surface. In this embodiment, the projection of the burner onto the placement surface extends beyond the outer contour of the placement surface 10a. It will be appreciated that when the telescopic assembly 131 is in the first position, the telescopic mechanism 131 may still extend along the central axis, i.e. away from the position of the telescopic mechanism when the lighting device is in the storage mode. When the telescopic assembly 131 is in the first position, the telescopic mechanism 131 extends along the central axis to a length limit value, i.e. the longest state, of the telescopic mechanism 131. And at this time, the lighting device 10 can be stably placed on the ground or the working surface without depending on external force, and is supported by the placing surface 10a.

In the second position of the telescopic assembly 131, as shown in fig. 1 and 5, the central axis 101 is substantially perpendicular to the placement surface 10a, and it should be explained that in actual adjustment, the central axis is not completely perpendicular to the placement surface 10a due to tolerance or manufacturing errors, and measurement-related errors, and thus the perpendicular or substantially perpendicular should be considered as disclosing a range defined by the absolute values of the two end points. Vertical or substantially vertical arrangement may refer to the central axis 101 being at an angle of 90 deg. plus or minus a percentage (e.g., 1%,5%,10% or more) to the placement surface 10a.

In some embodiments, as shown in fig. 4, retraction assembly 131 further includes a plurality of rotational positions 131c in addition to first position 131a and second position 131b, including, but not limited to, central axis 101 at 45 °, 60 °, 75 ° from placement surface 10a.

It is understood that the angle α between the central axis 101 and the placement surface 10a refers to an acute angle formed by the central axis 101 and the placement surface 10a. In the present embodiment, the telescopic assembly 131 is rotatably connected to the base 11a with the second axis 102 as a rotation axis. The second axis 101 is perpendicular to the central axis 101. The telescopic member 131 rotates about the second axis 102 in a range of 0 ° to 180 ° with respect to the base 11a. Therefore, when the included angle between the central axis 101 and the placement surface 10a is determined, the angles between the central axis 101 and the placement surface 10a are all greater than or equal to 0 ° and less than or equal to 30 ° when the telescopic assembly 131 rotates to 0 ° to 30 ° and 150 ° to 180 ° relative to the base 11a with the second axis 102 as the rotation axis, that is, all the angles belong to the telescopic assembly 131 being in the first position 131a.

In this embodiment, the telescopic component 131 drives the lamp cap 121 to displace, and when the included angle between the central axis 101 of the telescopic component 131 and the placement surface 10a is greater than or equal to 0 ° and less than or equal to 30 °, the lamp cap 121 is closer to the placement surface 10a, so that the lighting device 10 in this embodiment can also use a shorter working condition and still be used stably. Unlike the illumination mechanism directly started in the storage mode, the telescopic assembly can still extend freely when the included angle between the central axis 101 of the telescopic assembly 131 and the placement surface 10a is greater than or equal to 0 ° and less than or equal to 30 °. And can be stably placed without external force support or holding. The lighting device 10 is configured for optimal illumination in a variety of operating conditions. The service scene of the bracket lamp or the standing bracket lamp is enlarged.

As illustrated in fig. 14 to 16, the base 121 includes: a base housing 121a and a lamp plate 1213. The lamp base 1213 is accommodated in the cap housing 121a, and the luminous flux of the light emitted from the cap 121 at the maximum power is 2200lm or more and the luminous flux of the light emitted from the cap 121 at the maximum power/the weight of the cap 121 is 9lm/g or more. In some embodiments, the weight of the base 121 is 310g or less. The weight of the base 121 is reduced and the luminous flux of the lighting tool is not affected. The lightweight design of the base 121 facilitates a stable center of gravity of the support lamp, in particular a standing support lamp with telescopic height adjustment. So that the standing lamp has various use conditions.

The lighting device 10 is described below by taking a standing mode as an example.

As shown in fig. 1, 3, 5, and 7 to 10, in the standing mode, the placement surface 10a of the support mechanism 11 supports the lighting device 10 for stable placement on the ground or the work surface without depending on an external force. The placement surface 10a of the support mechanism 11 is formed by at least one surface of the base 11a and the end portions of the support legs 11b. The support mechanism 11 further includes a first locking assembly 11c connecting the base 11a and the support leg 11b. The support leg 11b is rotatably connected to the base 11a about a third axis 103, and the first locking assembly 11c is configured to maintain the support leg 11b in a plurality of rotational positions relative to the base 11a. In the present embodiment, the number of support legs 11b is one. The third axis 103 is perpendicular to the second axis 102. The support leg 11b rotates within a range of 360 ° about the third axis 103 with respect to the base 11a. The third axis 103 passes through the first locking assembly 11c.

The base 11a is substantially rectangular. As shown in fig. 3 and 7, the base 11a has a length direction F1, a width direction F2, and a height direction F3. The dimension of the base 11a in the length direction F1 is larger than the dimension of the base 11a in the width direction F2 and larger than the dimension of the base 11a in the height direction F3. In the present embodiment, the base 11a includes a front end 112 and a rear end 113 in the length direction F1, an upper end 114 and a lower end 115 in the height direction F3, and a left end 116 and a right end 117 in the width direction F2.

The support leg 11b also extends along the length direction of the base 11a, and the middle position of the support leg 11b is rotatably connected with the front end 112 of the base 11a through the first locking assembly 11c. The specific shape of the support leg 11b is not limited to a rectangular shape. In some embodiments, the support leg 11b may also be formed as a T-shaped, Y-shaped, or other profiled mechanism.

As shown in fig. 7, the longitudinal direction F1' defining the support leg 11b coincides with the longitudinal direction F1 of the base 11a by a relative rotation of 0 ° and 360 °. The support leg 11b is in an initial state with respect to the base 11a at this time. As shown in fig. 1 and 8, when the support leg 11b rotates relative to the base 11a, the longitudinal direction F1' of the support leg 11b makes a rotation angle with the longitudinal direction F1 of the base 11a. Both ends of the support leg 11b extend beyond the base 11a in the width direction F2, i.e., the left and right sides, with respect to the base 11a, thereby enlarging the area of the placement surface 10a. The stability of the support of the lighting device 10 by the support mechanism 11 is increased. In the present embodiment, the support leg 11b extends in the length direction by the length of the base 11a when the support leg 11b is in the initial state. With the support legs 11b in the initial state, as shown in fig. 3 to 5, the lighting device 10 may still be in a standing mode, and the telescopic assembly 131 may drive the base 121 away from and close to the base 11a.

In the present embodiment, the support mechanism 11 includes a first support position and a second support position. As shown in fig. 1 to 4, the supporting mechanism 11 is in the first supporting position, and the base 11a is located at the first side surface of the lower end 115 and forms the placement surface 10a with the first end 118 of the supporting leg 11b. Wherein the first end 118 includes a plurality of raised contact surfaces 1181 that may be configured to allow for clearance and adjustment when the ground or work surface is uneven. As shown in fig. 5 to 6, the supporting mechanism 11 is in the second supporting position, and the second side surface of the base 11a at the rear end 113 forms the placement surface 10a. Wherein the rear end 113 portion of the base 11a has a greater weight than the front end 112 portion of the base 11a. In the present embodiment, the battery pack 30 is mounted on a portion of the base 11a near the rear end 113. Such as near the left or rear side of the rear end 113.

In other alternative embodiments, when the length of the support leg 11b extends to the rear end 113 of the base 11a, the second side surface and the second end of the support leg 11b form the placement surface 10a when the support mechanism 11 is in the second support position. In the present embodiment, the supporting mechanism 11 includes a plurality of supporting positions, and the working condition of the illumination mechanism 12 that can be used is further expanded due to the different areas of the placement surfaces 10a of the different supporting positions. In some embodiments, the supporting mechanism 11 further includes a third supporting position and more, and different shapes may be set for the base 11a to achieve different supporting positions.

In some alternative embodiments, the ends of the support legs 11b are rotatably connected to the base 11a. The specific shape of the support leg 11b and the connection position with the base 11a are not limiting as to the essential content of the present application. The support leg 11b is attached to the base 11a through one rotation axis as a member that forms the placement surface 10a together with the base 11a, and the area of the outer contour of the placement surface 10a is adjusted by adjusting the positional relationship between the support leg 11b and the base 11a. It should be noted that the outer contour of the placement surface 10a means that all portions of one base 11a and support leg 11b contacting the ground or the working surface are covered in shape. Alternatively, it is understood that the projections of the base 11a and the support legs 11b are each covered with a circular or rectangular shape along an aspect perpendicular to the ground or the working surface.

With continued reference to fig. 9-10, the first locking assembly 11c includes an operating member and a first locking structure 119. In this embodiment, the operating member is used for a user to operate and drive the locking structure to act. The operating member is provided at the support leg 11b or the base 11a. In the present embodiment, the operation member is a support leg 11b. In some embodiments, the operating member may be disposed at other locations of the lighting device 10. The operating member may be mechanically driven or electronically driven.

The first locking structure 119 includes: a first gear tooth 1192 connected to the base 11a, a second gear tooth 1193 connected to the support leg 11b, and a biasing element 1191 biasing the first gear tooth 1192 and the second gear tooth 1193 in close proximity. The first shift position tooth 1192 and the second shift position tooth 1193 are each provided with a protruding surface and first and

second engagement teeth

119a and 119b that are recessed inwardly in cooperation therewith along the circumferential direction of the third axis 103. After the engagement teeth of the first gear tooth 1192 and the second gear tooth 1193 are engaged with each other, the relative rotational displacement of the first gear tooth 1192 and the second gear tooth 1193 is restricted. Wherein the biasing element 1191 is connected between the support leg 11b and the second gear tooth 1193. The second gear tooth 1193 is circumferentially and limitedly connected to the support leg 11b, and the second gear tooth 1193 is axially displaced along the third axis 103 to compress the biasing element 1191. First gear tooth 1192 is formed or attached to base 11a. The engagement teeth are provided with a guide surface and a limit surface. When the support leg 11b is rotated, the second gear tooth 1193 is forced to rotate, and the limiting surface is driven by the first gear tooth 1192, the second gear tooth 1193 biases the biasing element 1191, so that the second gear tooth 1193 compresses the biasing element 1191, and the limiting surfaces of the two engaging teeth of the first engaging tooth 119a and the second engaging tooth 119b are engaged and disengaged. Continuing to rotate the support leg 11b, the limiting surface contacts with the next limiting surface after passing through the guiding surface, and the biasing element 1191 applies a biasing force to the second gear tooth 1193 towards the direction of the first gear tooth 1192, so that if no external force is applied to continue to rotate the support leg 11b, the engaging teeth of the first gear tooth 1192 and the second gear tooth 1193 are engaged with each other. In the present embodiment, the relative rotational position of the support leg 11b and the base 11a is determined according to the number and spacing of the engagement teeth on the first gear teeth 1192 and the second gear teeth 1193. In this embodiment, the first locking structure 119 further comprises a second biasing element 1195 and a ball 1194 for rotational guidance and limitation. Wherein the second biasing element 1195 is compressed and released in the third axial direction, the second biasing element 1195 is disposed within the base 11a. Specifically, the first gear teeth 1192 are disposed along the outer periphery. The ball 1194 contacts the second biasing member 1195 and the support leg 11b, respectively. When the support leg 11b rotates, the ball 1194 rolls itself with the support leg 11b. The second biasing member 1195 may be elastically deformed to equalize the axial and circumferential movement of the support leg 11b. In some embodiments, the first gear tooth 1192 and the second gear tooth 1193 may be used in a shift position. The second biasing member and ball are disposed within the support leg. And are not disclosed herein in any way without affecting the essence of the present application.

In some alternative embodiments, the locking structure comprises a motor, pneumatic, hydraulic or damping mechanism, the stop of which is not affected by the mechanical limiting mechanism, allowing a stepless adjustment of the relative position of the support leg 11b with respect to the base 11a.

In the present embodiment, in order to increase the weight of the supporting mechanism 11 so that the lighting device 10 can be stably placed in various forms, the battery pack 30 is disposed on the base 11a. In other alternative embodiments, the weight of the support mechanism 11 may be increased by increasing the weight of the base 11a or by adding other structures. When the telescopic assembly 131 moves between the first position and the second position, the projection of the center of gravity G of the lighting device 10 is located within the outer contour of the supporting mechanism 11, and in the up-down direction, the center of gravity is close to the supporting mechanism 11.

As shown in fig. 11 to 13, the connection mechanism 13 further includes a second locking assembly 132 that connects the telescopic assembly 131 and the base 11a. The telescopic assembly 131 is rotatably connected to the upper side of the base 11a by a second locking assembly 132. In the present embodiment, a hinge seat 1121 is formed at an upper side of the base 11a, and the second locking assembly 132 is rotatably coupled to the hinge seat 1121. The second axis 102 passes through the hinge mount 1121.

The second locking assembly 132 includes: a body portion 132a, a second operating member 1321, a first guide tooth 1322, a first guide groove 1323, a first limit tooth 1325, a first limit groove 1324, and a third biasing element 1326. Wherein the second operating member 1321 slides and rotates within the body portion 132a. The body 132a is fixedly connected to the telescopic member 131. The first guide teeth 1322 are disposed on the outer side surface of the second operating member 1321, and the first guide teeth 1322 are uniformly protruded in the circumferential direction. The first guide groove 1323 is provided on the inner sidewall of the hinge seat 1121. The first guide teeth 1322 are operated to axially slide within the first guide grooves 1323. The second operating member 1321 and the hinge base 1121 are restrained from rotating about the second axis 102 by the engagement of the first guide teeth 1322 and the first guide grooves 1323.
