The existing camping lamp cannot achieve the effect of simultaneously considering three properties of portability, storage performance and illumination range, and the common camping lamp convenient to carry cannot provide various illumination ranges and illumination brightness selections; or can only be used as the lantern and use, optimized portability, but when it does not use, because lamp shade 24 is located the outside of lantern, damage lamp shade 24 easily when accomodating to in order to increase the illumination zone, lamp shade 24 uses 360 to encircle the setting, has further increased the degree of difficulty of accomodating, causes lamp shade 24 to damage easily.

The inventor of the present application has thus developed a camping lamp, one embodiment of which is shown in fig. 1 to 22, comprising a base 1 and a lamp cap assembly 2, wherein the lamp cap assembly 2 is rotatably disposed on the left and right sides of the base 1, and the external force along the circumferential direction is adapted to drive the lamp cap assembly 2 to rotate so as to be in a storage mode disposed opposite to each other and a lantern mode disposed opposite to each other; the lamp cap assembly 2 comprises a lamp cap seat 23 and a lamp shade 24, wherein an accommodating cavity 25 is defined by the lamp shade 24 and the inner wall of the lamp cap seat 23, a reflecting bowl 21 and an LED lamp panel 22 are arranged in the accommodating cavity 25, and the LED lamp panel 22 is fixedly arranged at the focus of the reflecting bowl 21; when in the storage mode, the lamp covers 24 on the left side and the right side are arranged oppositely, the reflecting bowl 21 on the left side and the right side are also arranged oppositely, the reflecting bowl 21 is in a concave state, and the bowl mouth of the reflecting bowl 21 faces to the inner side; when in the lantern mode, the lamp covers 24 on the left side and the right side are arranged in a back-to-back manner, the reflecting bowl 21 on the left side and the right side are also arranged in a back-to-back manner, and the external force along the left-to-right direction is suitable for forcing the lamp holder 23 to elastically deform and invade the accommodating cavity 25, and the lamp holder 23 is suitable for driving the LED lamp panel 22 to move outwards and driving the bowl bottom of the reflecting bowl 21 to move outwards until the reflecting bowl 21 is in a protruding state.

The inventor of the present application has developed a camping lamp having various operation modes including a storage mode, a lantern mode and a camping mode, in which, when in the storage mode, as shown in fig. 1, lamp cap assemblies 2 are arranged opposite to each other from left to right, lamp covers 24 are also arranged opposite to and facing inward, and a lamp cap base 23 for fixing the lamp covers 24 is arranged at the outer side of the lamp covers 24, so that the lamp covers 24 can be protected from being damaged by being pressed by a heavy load; when the lamp is in the lantern mode, as shown in fig. 2a and 2b, the lamp cap assembly 2 is driven to rotate circumferentially, so that the lamp cap bases 23 are arranged oppositely, and the lamp covers 24 are arranged oppositely and face outwards, so that the light rays emitted by the LED lamp panels 22 can pass through the lamp covers 24 to be emitted outwards; when in camping mode, as shown in fig. 3, the lamp cap assembly 2 is driven to rotate downwards, so that the angle between the lamp cap assemblies 2 arranged in opposite directions is enlarged, the illumination range of the lamp cap assembly 2 is changed, and the lamp cap assembly is matched with the external support 100, so that illumination in a larger range can be realized, and the camping use is more convenient. In addition, the handle 200 is further arranged on the lamp cap assembly 2, so that the lamp cap assembly is convenient to carry and store, and the lamp cap assembly 2 is convenient to rotate through the handle 200.

It should be noted that, in the storage mode, as shown in fig. 4, the reflective bowl 21 disposed in the accommodating cavity 25 is also disposed opposite to each other, and the reflective bowl 21 is in a concave state; in the state shown in fig. 4, the lamp cap assembly 2 is rotated along the circumferential direction, and the lamp cap assembly 2 is rotated downwards, so that the camping lamp is in a camping mode, as shown in fig. 3, the reflector 21 is still in a concave state, light rays emitted by the LED lamp panel 22 can be focused and emitted by the reflector 21, the maximum application of the light rays is realized, illumination of an angle (namely, light focusing, brightness increase and increase of luminous flux of a position facing the lamp shade 24) is realized through the external bracket 100, and at the moment, most of the light rays emitted from the lamp shade 24 are emitted in parallel under the action of the reflector 21, and the ground clearance of the lamp cap assembly 2 is increased through the external bracket 100, so that a better illumination effect is realized; at this time, the lamp cap assembly 2 is driven to rotate upwards, that is, the angle between the two lamp cap assemblies 2 is reduced, the two lamp cap assemblies 2 are arranged in opposite directions and are parallel to each other, at this time, an external force in the left-right direction is applied, the back of the lamp holder 23 is forced to elastically deform and invade the accommodating cavity 25, as shown in fig. 5 to 7, thereby driving the LED lamp panel 22 to move outwards, and driving the bowl bottom of the reflector 21 to move outwards, so that the reflector 21 is in a convex state, when the reflector 21 is in a convex state, the reflector 21 does not generate a condensation effect, and the distance between the LED lamp panel 22 and the lamp shade 24 is reduced, so that light rays emitted by the LED lamp panel 22 are directly emitted from the lamp shade 24 due to no condensation effect, at this time, the angle between the light rays emitted from the lamp shade 24 is large, and illumination (that light rays scatter, brightness is reduced, but illumination range is enlarged) in a larger range in space is realized, and the use of the lantern is more facilitated. In addition, when the lantern is used as the lantern, due to light scattering, the illumination range of the lantern is larger, the surrounding environment is more convenient to observe, and the visual angle is increased.

The reflecting bowl 21 has two working states, namely a concave state and a convex state, when the reflecting bowl 21 is in the concave state, each reflecting surface 213 of the reflecting bowl 21 is arranged inwards, and light rays emitted by the LED lamp panel 22 are focused and emitted under the action of the reflecting bowl 21; when the reflector 21 is in a convex state, each reflective surface 213 of the reflector 21 is arranged outwards, and light emitted by the LED lamp panel 22 is directly output without being reflected by the reflector 21, so that the LED lamp panel has a larger illumination angle and illumination range.

As shown in fig. 2a and fig. 5, the lamp shade 24 is provided with a plurality of light emitting surfaces 241, the light emitting surfaces 241 are not parallel to each other, and the plurality of light emitting surfaces 241 can cooperate with the convex state of the reflector 21 to realize that light rays with multiple directions and multiple angles can be emitted from the light emitting surfaces 241, so as to realize a larger range of illumination effect in the lantern mode. As shown in fig. 4, the reflective surfaces 213 are disposed opposite to each other, and the reflector 21 is in a concave state.

As a preference, as shown in fig. 1 to 7, the number of the lamp cap assemblies 2 is two, and is distributed on the left and right sides of the base 1; the base 1 is provided with a rotary connecting component 11 corresponding to the lamp cap component 2, the bottom of the lamp cap component 2 is rotatably connected with the rotary connecting component 11, and external force along the circumferential direction is suitable for driving the lamp cap component 2 to rotate around the rotary connecting component 11; the distance between the rotary connecting component 11 and the front surface of the lampshade 24 is L1, the distance between the rotary connecting component 11 and the back surface of the lamp holder 23 is L2, and the condition that L2 is more than L1 is satisfied. As shown in fig. 4 and 5, the lamp cap assembly 2 is circumferentially rotated according to the arrow direction, so that the lamp cap assembly 2 can be switched from a storage mode in which the lamp cap assembly is oppositely arranged to a storage mode in which the lamp cap assembly is oppositely arranged, and the external force along the arrow direction in fig. 5 drives the lamp cap base 23 to elastically deform so as to invade the accommodating cavity 25, so that the switching of the lantern mode can be completed.

The distance between L1 and L2 is very important, because in the lantern mode, the thickness of the lantern needs to be reduced as much as possible for convenience in carrying, and in the camping mode or the storage mode, the requirements of protection, heat dissipation, sealing and the like of the lampshade 24 need to be increased, and the volume of the accommodating cavity 25 needs to be increased, so that the elastically deformable lamp holder seats 23 are arranged to realize the requirements of accommodating cavities 25 with different volumes, and when l1=l2, the lamp holder seats 23 of the two lamp holder assemblies 2 do not collide with each other in the lantern mode, so that the thickness is not reduced in the lantern mode, and the lantern is inconvenient to carry; when L1 > L2, the distance between the bases 23 of the two base assemblies 2 is greater when in lantern mode, further reducing portability. Therefore, when L2 > L1 is required, the distance between the two lamp holders 23 can be reduced in the lantern mode, and the overall thickness and the volume can be reduced.
