In this embodiment, the reflective structure 15 can slide along the outer wall of the transparent lampshade 14, so that the reflective cup 153 is sleeved around the LED light source 13, and light is reflected by the reflective cup 153 and emitted from the light outlet 1533, or the LED light source 13 is separated from the reflective cup 153, the LED light source 13 is covered with the lens 12, the lens 12 is gradually thickened from the middle to the periphery, and the light is refracted by the lens 12, so that the light emitting direction of the light is changed, the light emitted towards the transparent lampshade 14 can be increased, the utilization rate of the light towards the transparent lampshade 14 is improved, and the light intensity emitted from the transparent lampshade 14 is enhanced.

The lamp 1000 in this embodiment is a flashlight.

In the present embodiment, the lamp base 11 is cylindrical, the light-transmitting lamp cover 14 sleeved outside the lamp base 11 is cylindrical, and the light-reflecting structure 15 sleeved outside the light-transmitting lamp cover 14 is cylindrical.

Specifically, the LED light source 13 is mounted on the top of the lamp holder 11, the LED light source 13 is a patch LED lamp, and light of the LED light source 13 is scattered around. In other embodiments, the LED light source 13 may also be an LED lamp with a bulb, which is not limited herein.

Specifically, the lens 12 is a concave lens, and the thickness of the concave lens is thin in the middle and thick around, and gradually increases from the middle to the periphery. The lens 12 of the present embodiment may be a biconcave lens or a plano-concave lens.

The LED light source 13 is covered in the recess 121 of the lens 12, and the light of the LED light source 13 diverges from the other side after being refracted by the recess 121, and since the periphery of the lens 12 is a plane, the light emitted from the cambered surface of the recess 121 toward the periphery can be refracted in parallel and emitted from the light-transmitting lampshade 14.

Specifically, the transparent lampshade 14 is made of transparent material, so that the light of the LED light source 13 is emitted through the transparent lampshade 14. Of course, in other embodiments, the light-transmitting lampshade 14 may also be a hollowed lampshade, so that the light of the LED light source 13 is emitted from the hollowed-out portion, which is not limited herein.

In this embodiment, the lower end of the transparent lampshade 14 is fixed to the lamp base 11, the reflective structure 15 includes a sliding seat 151, the sliding seat 151 is sleeved outside the transparent lampshade 14 from above and can slide relative to the transparent lampshade 14, the upper end of the reflective cup 153 is fixed to the sliding seat 151, the reflective cup 153 can slide synchronously with the sliding seat 151, the reflective cup 153 is in a horn shape, and an opening 1532 of the reflective cup 153 facing one side of the LED light source 13 can be penetrated by the lens 12. The end of the reflecting cup 153 opposite to the opening 1532 is provided with a light outlet 1533, and the light reflected by the reflecting cup 153 is emitted from the light outlet 1533.

The LED light source 13 can enter the reflecting cup 153 through the opening 1532 and move towards the light outlet 1533, so that the LED light source 13 is positioned between the opening 1532 and the light outlet 1533, and the light of the LED light source 13 is reflected by the reflecting cup 153 to realize the function of spot lighting; the light can be separated from the reflecting cup 153 and moved towards the direction away from the light outlet 1533, so that the light of the LED light source 13 is emitted from the light-transmitting lampshade 14 towards the periphery in a divergent manner, and the function of ring illumination is realized.

Under the condition that the reflecting cup 153 slides to the position that the LED light source 13 is separated from the opening 1532 and the reflecting cup 153 is arranged, the lens 12 is covered outside the LED light source 13, light around the light is emitted towards the side, the light is refracted by the lens 12, the utilization rate of the light towards the light-transmitting lampshade 14 can be improved, the intensity of the light emitted from the light-transmitting lampshade 14 is enhanced, the circular illumination light distribution curve is as shown in fig. 12, the circular illumination function is realized, and the circular illumination light can be used as a circular illumination lamp at the moment.

Compared with the LED light source 13 without the lens 12, the lens 12 is covered on the LED light source 13, so that the light emitted horizontally towards the periphery can be increased, and the ambient light can be brighter.

When the light reflecting cup 153 slides to the bottom end of the LED light source 13 and the opening 1532 is level, the light reflecting cup 153 is covered outside the lens 12, light is refracted onto the light reflecting cup 153 through the lens 12, at this time, the light is emitted from the light emitting hole 1533 under the action of the light reflecting cup 153, a first light spot is generated on a plane by irradiation, and the light distribution curve of the first light spot is as shown in fig. 10, so that the function of spot light illumination is realized.

When the reflecting cup 153 slides to the opening 1532 and abuts against the top end of the lamp holder 11, the light is refracted onto the reflecting cup 153 through the lens 12, the light is emitted from the light emitting hole 1533, and irradiates on a plane to generate a second light spot, and the light distribution curve of the second light spot is as shown in fig. 11, so that the function of spot light illumination is realized. Because the LED light source 13 is closer to the light exit hole 1533 at this time, the size of the second light spot is larger than that of the first light spot, so that the light condensing effect of the second light spot is not as good as that of the first light spot, the second light spot is suitable for large-range light condensing illumination and can be used for outgoing path illumination, and the first light spot is suitable for local small-range light condensing illumination and can be used for fine operation illumination.

When the light source enters the light reflecting cup 153 and slides along with the light reflecting cup 153 far away from the light source, light is reflected and diverged through the light reflecting cup 153 to form light spots which gradually change from small to large, the position of the LED light source 13 in the light reflecting cup can be adjusted by sliding the light reflecting cup according to requirements, the light can be switched between a spotlight function or a floodlight function, and the flashlight can be used as a flashlight.

Since the light of the LED light source 13 is refracted by the lens 12, the light is refracted onto the reflective cup 153, and is reflected by the reflective cup 153 and emitted toward the light outlet 1533, the lens 12 is arranged on the outer cover of the LED light source 13, so that the effect of spot lighting is not affected, but the ring illumination light emitted horizontally around is enhanced.

In this embodiment, the lens 12 is a plano-concave lens, and one side of the lens 12 facing the LED light source 13 is concave 121 inward to form a spherical surface, and the other side is a cambered surface.

The inner wall of the recess 121 may be tapered, curved or rectangular, and the specific shape is not limited herein. In this embodiment, the shape of the recess 121 is an arc surface.

The LED light source 13 is covered in the concave 121 of the lens 12, and the light of the LED light source 13 is refracted to the cambered surface of the other side through the cambered surface of the concave 121, and is refracted again after reaching the cambered surface, and then is emitted from the light-transmitting lampshade 14.

Since the light of the LED light source 13 is emitted divergently, it reaches the conical surface of the lens 12 after being refracted by the cambered surface of the recess 121, and the conical surface of the lens 12 is refracted again to be emitted toward the light-transmitting globe 14. Because the lens 12 is conical, the area of the periphery of the lens 12 facing the light-transmitting lampshade 14 is larger than the area facing the opening 1532, the light emitted in the direction facing the opening 1532 is greatly reduced, the light emitted in the direction facing the light-transmitting lampshade 14 is increased by refraction of the lens 12, and compared with the case that the lens 12 is not covered on the LED light source 13, the light scattered in the periphery is increased to a greater extent, the utilization rate of the light facing the periphery is improved, and the intensity of the ring illumination is enhanced.

In other embodiments, the lens 12 may be a biconcave lens, where the biconcave lens is covered around the LED light source 13, and the LED light source 13 is located below the middle of the lens 12, and since the biconcave lens is planar around, the light beam is refracted by the recess 121 and then reaches the plane, and the light beam does not change the direction of the light beam and is emitted after reaching the plane.

Example III

Referring to fig. 5 and 7, in the present embodiment, a conical recess 121 is formed on a side of the lens 12 facing the LED light source 13.

Therefore, the light emitted to the conical surface of the concave 121 is also emitted towards the outer side of the lens 12 through the conical surface refraction of the concave 121, the conical surface is formed on the outer side of the lens 12, the light can be refracted again after reaching the conical surface of the lens 12, and the utilization rate of the ring illumination light can be improved to the greatest extent after the light is refracted twice.

Specifically, the concave 121 formed inward of the lens 12 toward the LED light source 13 side is tapered, and the thickness of the lens 12 is also increased from the middle toward the periphery.

In this embodiment, the central axis of the recess 121 coincides with the central axis of the lens 12, and meanwhile, the center of the LED light source 13 coincides with the central axis of the lens 12, the LED light source 13 diffuses toward the periphery, and since the light emitted to the central axis of the recess 121 can be directly emitted without refraction, the light emitted to the conical surface of the recess 121 can be emitted toward the outer side of the lens 12 through the refraction of the conical surface of the recess 121, the conical surface is also formed on the outer side of the lens 12, the light can be refracted again after reaching the conical surface of the lens 12, and after twice refraction, a large amount of scattered light is refracted to the greatest extent into the light toward the periphery, so that the light intensity of the periphery is enhanced.

The area of the cone-shaped recess 121 for receiving incident light is small, so that light emitted from the cone toward the light emitting hole 1533 of the reflector cup 153 is greatly reduced, light toward the periphery of the lens 12 is increased, the light emitting rate of the periphery of the lens 12 is effectively improved, and the utilization rate of the ambient light is maximally improved under the condition of the ambient illumination mode.

The specific refraction route of the light is as follows: the LED light source 13 is turned on, light is scattered around, light is emitted to the concave 121, light emitted to the central axis of the concave 121 is directly emitted without refraction, light emitted to the conical surface of the concave 121 is refracted around the other side of the lens 12 opposite to the concave 121, light reaching the outer side of the lens 12 is refracted around the lens 12 again, so that light originally facing the direction of the reflective cup 153 is changed to be emitted from the light-transmitting lampshade 14 after two times of refraction.

In other embodiments, the LED light source 13 is an LED lamp with a bulb, and the recess 121 may be changed according to the shape of the bulb of the LED lamp, so that the LED light source 13 can be placed in the recess 121, and the specific shape is not limited herein.
