When the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.
[0032] The present application proposes a multi-light-source lighting device 100, please refer to Figs. 1-6, including a shell 1 and a lighting component 2; the lighting component 2 is connected to one end of the shell 1, the lighting component 2 comprises a mounting cavity 21, the mounting cavity 21 is provided with a lighting system 3, the lighting system 3 comprises an LED lamp group 31 and a light-transmitting lens group 32, the light-transmitting lens group 32 comprises a floodlight lens 321 and a spotlight lens 322, the spotlight lens 322 is provided with a channel 3221 in the middle, and the floodlight lens 321 is inserted into the channel 3221; wherein the floodlight lens 321 is provided with a light guide groove 3211 at one end facing the LED lamp group 31, the groove notch 3212 of the light guide groove 3211 is opposite to the LED lamp group 31 to guide the light source emitted by the LED lamp group 31 into the spotlight lens 322, and the diameter of the floodlight lens 321 opposite to one end of the LED lamp group 31 is greater than the diameter of the LED lamp group 31.
[0033] The shell 1 serves as a holding part of the multi-light source lighting device 100, and in order to facilitate the user to hold, the material of the shell 1 can be selected as polyvinyl chloride, which is light in weight and not easy to cause fatigue of the user in long-time use. In addition, the polyvinyl chloride also has good strength and toughness, can resist high-strength impact force and is not easy to be damaged, protects the electronic components inside the multi-light source lighting device 100 and prolongs the service life of the multi-light source lighting device 100. Further, in order to reduce the friction between the hand skin of the user and the shell 1, the shell 1 can be made of soft polyvinyl chloride, which is soft and elastic, and is not easy to cause friction damage to the skin of the user after long-time use of the multi-light source lighting device 100, thereby improving the use comfort of the user. Of course, the above is only exemplary, and the specific material can be determined according to actual needs, and the utility model is not limited herein.
[0034] The lighting component 2 is one of the core components of the multi-light source lighting device 100, and can emit light to the external environment under the control of the circuit board by being electrically connected with the electronic components inside the shell 1, for example, the circuit board. Further, the lighting system 3 is arranged in the mounting cavity 21 of the lighting component 2, and the lighting system 3 comprises the LED lamp group 31 and the light-transmitting lens group 32. The circuit board controls the LED lamp group 31 to emit light to the light-transmitting lens group 32, so that the light can be emitted to the external environment and the lighting is realized.
[0035] In some embodiments, the multi-light source lighting device 100 has a floodlighting mode. Please refer to Fig. 3 and Fig. 4 The light-transmitting lens group 32 comprises the floodlight lens 321, the LED lamp group 31 comprises a floodlight LED 311, and the floodlight LED 311 can emit a floodlight source. When the multi-light source lighting device 100 is switched to the floodlighting mode, the floodlight LED 311 emits a floodlight source with a beam angle of 60° to the floodlight lens 321. After the floodlight source enters the floodlight lens 321, it is reflected multiple times, and finally emitted to the external environment, forming a large-angle low beam light, realizing large-area low beam lighting.
[0036] It should be noted that the diameter of the one end of the floodlight lens 321 opposite to the LED lamp group 31 is greater than the diameter of the LED lamp group 31. Specifically, the diameter of the light-transmitting lens is greater than the diameter of the floodlight LED 311. After assembling the irradiation component, the bottom of the floodlight lens 321 can still cover the floodlight LED 311 after ensuring the maximum tolerance of the structural assembly, thereby maximizing the use of the floodlight light source.
[0037] In some embodiments, the multi-light source lighting device 100 of the utility model has a spotlighting mode. Please refer to Figs. 3-6 The light-transmitting lens group 32 includes a spotlighting lens 322, and the LED lamp group 31 includes a spotlighting LED 312, which is circularly arranged at the middle part of the floodlight LED 311. The groove bottom of the light guide groove 3211 protrudes to form a light guide surface 3213 in the direction of the LED lamp group 31, and the light guide surface 3213 is arc-shaped. When the multi-light source lighting device 100 is switched to the spotlighting mode, the spotlighting LED 312 emits a high-intensity and small-angle spotlighting light source toward the light guide groove 3211. Specifically, the angle of the spotlighting light source is 7°. The spotlighting light source enters the light guide groove 3211 through the groove opening 3212, part of the spotlighting light source is refracted by the groove wall of the light guide groove 3211 into the interior of the spotlighting lens 322, and then the spotlighting lens 322 reflects the part of the spotlighting light source to the outside environment relative to the vertical direction by the mirror wall. The remaining part of the spotlighting light source reaches the light guide surface 3213 of the groove bottom. Since the light guide surface 3213 is concave downward, the incidence angle of the spotlighting light source on the light guide surface 3213 is closer to the vertical direction, thereby reducing the reflection loss of the spotlighting light source, improving the light transmittance of the spotlighting light source, enabling more spotlighting light sources to be effectively emitted from the light guide surface 3213 and irradiated to the outside environment, forming a high-intensity far light spot, and highly converging the light rays to make the light intensity on the illuminated object higher than the surrounding environment.
[0038] It should be noted that the diameter of the groove opening 3212 of the light guide groove 3211 is smaller than the diameter of the spotlighting LED 312. Since there is a tolerance between the light-transmitting lens group 32 and the LED lamp group 31 when assembling the irradiation component, when the diameter of the groove opening 3212 is smaller than the diameter of the spotlighting LED 312, the error of the structural assembly can be compatible, and the spotlighting light source can be prevented from being emitted from the floodlight lens 321 after entering the light guide groove 3211, thereby preventing the spotlighting light source from appearing as a non-uniform bright circle.
[0039] In some embodiments, the multi-light source lighting device 100 of the utility model further has a spotlighting-floodlighting mode, in which the floodlight LED 311 and the spotlighting LED 312 emit light to the light-transmitting lens group 32 at the same time.
[0040] The utility model has the advantages of:
[0041] Firstly, by constructing the channel 3221 in the middle of the condenser lens 322, and inserting the floodlight lens 321 into the channel 3221, the light-transmitting lens set 32 is more compact in the installation cavity 21 of the illumination member, and does not occupy too much space of the installation cavity 21, and the layout of the whole illumination member 2 at one end of the shell 1 is also more reasonable and compact, which is beneficial to reduce the volume of the whole multi-light source illumination device 100, and facilitate carrying and using.
[0042] In addition, the light guide groove 3211 constructed at one end of the floodlight lens 321 towards the LED lamp set 31, and the slot 3212 of the light guide groove 3211 is opposite to the LED lamp set 31, which can effectively guide the light source emitted by the LED lamp set 31 into the condenser lens 322, reduce the dispersion and waste of light, and maximize the use of light emitted by the LED multi-light source lamp set, so that the illumination efficiency of the whole illumination device is improved, and better illumination brightness and effect are obtained under the same power consumption.
[0043] Finally, the diameter of the floodlight lens 321 opposite to one end of the LED lamp set 31 is greater than the diameter of the LED lamp set 31, so that the multi-light source illumination device 100 has good adaptability when facing LED lamp sets 31 of different specifications and different beam angles, without the need to make substantial changes to the overall structure, and the versatility of the multi-light source illumination device 100 is improved.
[0044] In some embodiments, please refer to Fig. 4 The condenser lens 322 is in a circular truncated cone structure, and the diameter of the first exit surface 3222 of the condenser lens 322 is greater than the diameter of the entrance surface 3223 of the condenser lens 322.
[0045] When the condensing light source is refracted from the light guide groove 3211 at the side of the entrance surface 3223 to the condenser lens 322, since the condenser lens 322 presents a shape gradually widening, the distance between the outer wall of the condenser lens 322 and the light guide groove 3211 gradually increases, and correspondingly, the refractive path of the condensing light source becomes larger, and finally a far light ray with a larger diameter is formed when exiting from the first exit surface 3222. When illuminating a target at a long distance, not only the central region has a strong brightness, but also a certain range around the central region is illuminated.
[0046] In some embodiments, please refer to Fig. 5 and Fig. 6 The floodlight lens 321 includes a first lens 3214 and a second lens 3215, a first step 3216 is constructed at the connection between the first lens 3214 and the second lens 3215, the channel 3221 is constructed with a second step 3224 matched with the first step 3216, and the first step 3216 abuts against the second step 3224 when the floodlight lens 321 is inserted into the channel 3221.
[0047] Firstly, when assembling the light-transmitting lens group 32, the floodlight lens 321 is inserted into the channel 3221 of the spotlight lens 322, and the first step 3216 abuts against the second step 3224. This design realizes the accurate positioning of the floodlight lens 321 in the spotlight lens 322. Through the mutual abutment between the steps, the axial position of the floodlight lens 321 in the channel 3221 can be accurately determined, avoiding the deviation of the installation position from the expectation, which leads to the poor lighting effect of the multi-light source lighting device 100, improving the efficiency and accuracy of the assembly, reducing the product failure rate caused by improper installation, and facilitating the smooth progress of the batch production process.
[0048] In addition, it can also avoid the axial sliding or displacement during use, ensuring the fixation of the relative position between the floodlight lens 321 and the spotlight lens 322. The light source emitted by the LED lamp group 31 can be refracted and propagated according to the designed lighting system 3 during the refraction from the light guide groove 3211 of the floodlight lens 321 to the spotlight lens 322, ensuring the overall optical performance of the light-transmitting lens group 32 and realizing more accurate light adjustment.
[0049] Finally, this step abutment structure makes the floodlight lens 321 and the spotlight lens 322 tightly combined together, which can effectively resist the influence of accidental bumps of the multi-light source lighting device 100, prevent the loosening and misalignment between the lenses caused by vibration, ensure the structural stability of the light-transmitting lens group 32 and even the entire lighting component 2, and further prolong the service life of the lighting device.
[0050] It should be noted that the first lens 3214 and the second lens 3215 are integrally formed, which ensures the continuity of the light path and the stable propagation of the floodlight source in the floodlight lens 321, helping to maintain stable and high-quality lighting effect. The integrally formed design enhances the connection strength between the first lens 3214 and the second lens 3215, avoids the phenomenon of breaking during use, and prolongs the service life of the multi-light source lighting device 100.
[0051] In order to improve the uniformity of the low beam spot of the floodlight source emitted from the floodlight lens 321, please refer to Fig. 7 and Fig. 8 The second emission surface 3217 of the floodlight lens 321 is provided with a plurality of light emission surface microstructures 3218, which are protruded from the second emission surface 3217 of the floodlight lens 321 in a dot shape. When the floodlight source passes through the refraction of the light emission surface microstructure 3218, the floodlight source will diverge outward, forming a larger effective illumination angle and achieving a larger range of illumination effect.
[0052] The light-exit surface microstructure 3218 has multiple choices.
[0053] The light-exit surface microstructure 3218 has multiple choices.
[0054] In some embodiments, the condensing lens 322 is a TIR lens (total internal reflection lens) for total internal reflection light source, controls the collimation of the light source, and is made of polycarbonate.
[0055] The total internal reflection characteristic of the TIR lens can minimize the loss of the light source caused by improper reflection and refraction when the light source propagates in the TIR lens.
[0056] The condensing lens 322 is made of polycarbonate and has excellent optical transparency and high transmittance to visible light, so that the light source can smoothly enter the condensing lens 322 when refracted from the light guide groove 3211 and be emitted to the outside through total reflection in the condensing lens 322 to achieve spotlighting.
[0057] The above are only some or preferred embodiments of the present application, and neither the text nor the drawings can limit the scope of protection of the present application. Any equivalent structural transformation or direct / indirect application in other related technical fields based on the content of the present application is included in the scope of protection of the present application.
