Description

Technical Field

[0001] This utility model belongs to the field of flashlight technology, and in particular relates to a high and low beam reflector module and a flashlight. Background Technology

[0002] Portable lighting devices such as flashlights and headlamps have become indispensable tools in various scenarios, including outdoor activities, emergency rescue, routine maintenance, and home backup. As users' demands for lighting functionality continue to increase, single high-beam lighting is no longer sufficient to meet the requirements of complex environments. Therefore, dual-source lighting devices with multiple beam patterns, such as high beam and low beam, are gradually becoming the mainstream in the market. These devices typically use a reflector structure to control the light source, transforming a point light source into an emitted beam with a specific beam pattern distribution through the design of the reflective surface, thereby achieving different lighting effects such as long-distance focused lighting and short-distance floodlighting.

[0003] However, in existing dual-light source flashlight designs, although the function of switching between high and low beams is realized, the low beam mode often suffers from poor beam uniformity. Specifically, this manifests as obvious unevenness in brightness and darkness, irregular shape, or localized overbrightness in the emitted beam, which seriously affects lighting comfort and visual experience.

[0004] Therefore, there is an urgent need for a high-beam and low-beam reflector module and flashlight that can improve the uniformity of the low-beam spot and visual comfort. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a high and low beam reflector module and a flashlight that can effectively control and optimize the light path. While ensuring high beam performance, it significantly improves the uniformity of the low beam spot and visual comfort, thereby enhancing the overall lighting quality and user experience.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high / low beam reflector module includes:

[0008] The reflector body includes a high beam reflector, the incident end of which is equipped with a high beam light source. The beam emitted by the high beam light source enters the high beam reflector through the incident end and is reflected and collimated by the inner wall of the high beam reflector, then exits from the exit end of the high beam reflector to form high beam. A light cup ring is arranged around the edge of the exit end of the high beam reflector, and multiple low beam reflectors are arranged around the light cup ring. The inner wall of the low beam reflector is a scale-like spliced ​​surface. A low beam light source is installed at the incident end of the low beam reflector. The beam emitted by the low beam light source enters the low beam reflector through the incident end and is reflected by the scale-like spliced ​​surface, causing its light path to disperse and overlap, and then exits from the exit end of the low beam reflector to form low beam.

[0009] Furthermore, the scale-like splicing surface is composed of multiple scale-like protrusions spliced ​​together.

[0010] Furthermore, the low beam light source includes a ring-shaped first substrate and multiple low beam LEDs arranged on the first substrate. The number of low beam LEDs is equal to the number of low beam reflectors. The first substrate is fitted onto the high beam reflector and installed at the incident end of the reflector ring assembly.

[0011] Furthermore, each of the low beam reflectors has a first mounting groove at its incident end, and the low beam LED is installed in the first mounting groove and extends into the first mounting groove.

[0012] Furthermore, the number of low beam reflectors on the light cup ring assembly is 12, and the number of low beam LEDs is 12, including 6 warm light LEDs and 6 cool light LEDs.

[0013] Furthermore, the high beam light source includes a second substrate and a high beam LED bead disposed at the center of the second substrate. The incident end of the high beam reflector is provided with a second mounting groove, and the high beam LED bead is correspondingly mounted to the second mounting groove.

[0014] Furthermore, a centering positioning plate is installed between the high beam light source and the second mounting slot, for the high beam lamp bead to be centered and aligned with the second mounting slot.

[0015] This utility model also provides a flashlight, including the aforementioned high and low beam reflector module, and further including a lamp body and a lamp head connected to the lamp body, wherein the high and low beam reflector module is installed inside the lamp head.

[0016] Furthermore, it also includes a glass and a pressure cap installed at the front end of the reflector body, the pressure cap being threadedly connected to the lamp head to fix the glass and the high and low beam reflector module inside the lamp head.

[0017] Furthermore, the lamp head is provided with an annular stepped portion, and the back of the low beam light source is mounted on the annular stepped portion.

[0018] The beneficial effects of this utility model are:

[0019] This invention utilizes a low-beam reflector with a scale-like splicing surface to disperse and overlap the low-beam light beam, reducing chromatic aberration and resulting in a uniform and soft low-beam spot. A first mounting groove at the incident end of each low-beam reflector facilitates precise positioning and installation of the low-beam LED, ensuring it is in the optimal reflection position and improving optical path control accuracy and light output efficiency. The inclusion of warm and cool-light LEDs allows for low-beam color temperature adjustment. A central positioning plate ensures precise alignment of the high-beam LED with the high-beam reflector. An annular stepped section within the flashlight head facilitates precise positioning and mounting of the low-beam light source. This invention enables effective control and optimization of the optical path, significantly improving the uniformity and visual comfort of the low-beam spot while maintaining high-beam performance, thereby enhancing overall lighting quality and user experience.

[0032] See appendix Figure 1 To be continued Figure 7The figure shows a specific embodiment of the high and low beam reflector module and flashlight provided by this utility model.

[0033] See appendix Figure 1 and attached Figure 2 The high and low beam reflector module includes:

[0034] The system includes a reflector body 1, which includes a high-beam reflector 110. A high-beam light source 2 is installed at the incident end of the high-beam reflector 110. The light beam emitted by the high-beam light source 2 enters the high-beam reflector 110 through its incident end, is reflected and collimated by the inner wall of the high-beam reflector 110, and exits from its exit end to form high beam. A light cup ring assembly 1 surrounds the edge of the exit end of the high-beam reflector 110. 20. Multiple low beam reflectors 130 are arranged around the light cup ring assembly 120. The inner sidewall of the low beam reflector 130 is a scale-like splicing surface 131. A low beam light source 3 is installed at the incident end of the low beam reflector 130. The light beam emitted by the low beam light source 3 enters the low beam reflector 130 through the incident end of the low beam reflector 130 and is reflected by the scale-like splicing surface 131, causing its light path to be dispersed and overlapped. Then it is emitted from the exit end of the low beam reflector 130 to form low beam.

[0035] See appendix Figure 6 and attached Figure 7 In the above embodiments, the high beam reflector 110 and the high beam source 2 work together to emit high beams for long-distance illumination, while the low beam reflector 130 and the low beam source 3 work together to emit low beams for short-distance flood illumination. Specifically, the beam of the high beam source 2 is reflected and collimated by the reflective surface of the inner wall of the high beam reflector 110, and the beam of the low beam source 3 is dispersed and overlapped by the scale-like splicing surface 131 within the low beam reflector 130, reducing dispersion and resulting in a uniform and soft emitted low beam spot, avoiding problems such as uneven low beam spots and localized overbrightness. For details, please refer to the appendix. Figure 3 and attached Figure 4 The scale-like splicing surface 131 is composed of multiple scale-like protrusions 132 spliced ​​together. In this embodiment, the scale-like protrusions 132 are convex curved surfaces, which realizes more precise and controllable reflection of the light path, optimizes the light distribution, and improves the uniformity of near-light.

[0036] See appendix Figure 2 and attached Figure 5In the above embodiment, the low beam light source 3 includes an annular first substrate 310 and multiple low beam LEDs 320 disposed on the first substrate 310. The number of low beam LEDs 320 is equal to the number of low beam reflectors 130. The first substrate 310 is fitted onto the high beam reflector 110 and installed at the incident end of the reflector ring assembly 120. Each low beam reflector 130 has a first mounting groove 133 at its incident end, and the low beam LEDs 320 are correspondingly installed in the first mounting groove 133 and extend into the first mounting groove 133. In this embodiment, by using an annular first substrate 310 and a corresponding number of low beam LEDs 320, a compact and integrated arrangement of the low beam light source 3 is achieved, which facilitates assembly and ensures that the low beam LEDs 320 correspond one-to-one with the low beam reflectors, thereby guaranteeing illumination efficiency and improving the accuracy of optical path control.

[0037] See appendix Figure 2 In the above embodiment, the number of low beam reflectors 130 on the reflector ring assembly 120 is 12, and the number of low beam LEDs 320 is 12, including 6 warm light LEDs and 6 cool light LEDs. In this embodiment, the cool light LEDs and warm light LEDs can be lit individually or all at once. When all the cool light LEDs and warm light LEDs are lit, the low beam spot not only has uniform brightness but also a moderate color temperature, resulting in a more comfortable visual experience.

[0038] See appendix Figure 5 In the above embodiment, the high beam source 2 includes a second substrate 210 and a high beam LED 220 disposed at the center of the second substrate 210. The incident end of the high beam reflector 110 is provided with a second mounting groove 111, and the high beam LED 220 is correspondingly mounted to the second mounting groove 111. In the above embodiment, a centering positioning plate 4 is also installed between the high beam source 2 and the second mounting groove 111 for centering the high beam LED 220 and the second mounting groove 111. In this embodiment, the centering positioning plate 4 achieves precise centering of the high beam source 2, enabling the high beam LED 220 to be precisely aligned with the focal point of the high beam reflector 110, facilitating assembly and ensuring that the high beam spot is centered and unbiased, thus guaranteeing the collimation and focusing effect of the high beam.

[0039] See appendix Figure 1 This embodiment also provides a flashlight, including the aforementioned high and low beam reflector module, a lamp body 5, and a lamp head 6 connected to the lamp body 5. The high and low beam reflector module is installed inside the lamp head 6. In this embodiment, the flashlight simultaneously possesses a high beam with excellent focusing and a uniform, glare-free low beam, achieving a high-quality illumination function with integrated dual beams.

[0040] See appendix Figure 1In the above embodiment, a glass 7 and a pressure cap 8 are also included, which are installed at the front end of the reflector body 1. The pressure cap 8 is threadedly connected to the lamp head 6 to fix the glass 7 and the high and low beam reflector module inside the lamp head 6. In the embodiment, the pressure cap 8 is screwed onto the lamp head 6 by threads, so as to firmly and sealingly fix the glass 7 and the reflector module inside the lamp head 6, thereby achieving a reliable protective effect.

[0041] See appendix Figure 1 In the above embodiment, the lamp head is provided with an annular stepped portion 610, and the back of the low beam light source 3 is mounted on the annular stepped portion 610. In this embodiment, the annular stepped portion 610 is used to support and fix the back of the first substrate 310, and the low beam lamp bead 320 is mounted on the front of the first substrate 310 and placed in the first mounting groove 133 of the low beam reflector 130. The annular stepped portion 610 makes the mounting structure of the low beam light source 3 in the lamp head 6 more stable.

[0042] In summary, this embodiment provides a high and low beam reflector module and a flashlight. By setting a low beam reflector 130 with a scale-like splicing surface 131, it achieves the dispersion and overlapping reflection of the low beam source 3, reducing dispersion and making the emitted low beam spot uniform and soft. By setting a first mounting groove 133 at the incident end of each low beam reflector 130, it facilitates the precise positioning and installation of the low beam LED 320, ensuring that the low beam LED 320 is in the optimal reflection position, improving the optical path control accuracy and light output efficiency. By setting warm-light and cool-light LED beads, the color temperature of the low beam can be adjusted; by setting a centering positioning plate 4, the high beam LED bead 220 can be precisely aligned with the focal point of the high beam reflector cup 110; by setting an annular stepped part 610 inside the flashlight head 6, the precise positioning and mounting of the low beam light source 3 can be facilitated; this embodiment can achieve effective control and optimization of the light path, while ensuring the performance of the high beam, significantly improving the uniformity of the low beam spot and visual comfort, thereby enhancing the overall lighting quality and user experience.
