Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to LED flashlights. Background Technology

[0002] LED flashlights are widely used in various lighting scenarios due to their compact size and ease of handheld use. Besides everyday lighting needs, they are also commonly used in photography and videography, outdoor lighting, and night fishing lights.

[0003] Depending on the usage scenario, the light emission requirements of flashlights vary. For example, in the field of everyday lighting, the main requirement for flashlights is high-brightness white light; while in the fields of photography, videography, and fishing lights, there are higher and more personalized requirements for light emission uniformity, color temperature, and color.

[0004] However, in these fields with high requirements for light parameters, the performance of current flashlights cannot meet the needs. For example, in flashlights with colored LEDs, the flashlight typically contains three large LEDs, and white or colored light is obtained by adjusting the emission of each LED. At the same time, in order to achieve uniform light mixing, a zoomable lens group is usually installed in front of the flashlight light source, and the different colored LEDs are mixed by focusing. However, this solution increases the structural complexity of the flashlight and results in insufficient color rendering consistency. Users are easily limited by their own dimming experience and cannot easily achieve the desired light output effect. Utility Model Content

[0017] In one embodiment of this application, the longitudinal distance from the upper surface of the connecting portion to the light source is fixed.

[0018] In one embodiment of this application, the LED flashlight further includes a heat dissipation component and a battery component; both the heat dissipation component and the battery component are mounted on the lamp body, and the heat dissipation component is located between the light source and the battery component to dissipate heat from the light source; the battery component is electrically connected to the light element and the heat dissipation component to provide electrical energy.

[0019] In one embodiment of this application, the LED flashlight further includes a control module; the control module is mounted on the lamp body and electrically connected to the light element to control the luminous brightness of different types of light emitters.

Detailed Implementation

[0034] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0035] In the description of this utility model, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications will also change accordingly.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] In fields with high requirements for light parameters, current flashlight performance cannot meet the needs. For example, flashlights with colored LEDs typically contain three large LEDs, and white or colored light is obtained by adjusting the emission of each LED. Simultaneously, to ensure uniform light mixing, a zoomable lens assembly is usually installed in front of the flashlight's light source, allowing for the mixing of different colored LEDs through focusing. However, this approach increases the structural complexity of the flashlight and results in insufficient color rendering consistency. Users are also easily limited by their own dimming experience, making it difficult to easily achieve the desired light output. Therefore, this paper proposes an LED flashlight to solve the above problems.

[0038] The solution is further illustrated by the following examples:

[0039] Figure 1 This is a schematic diagram of an LED flashlight according to an embodiment of the present invention. Figure 2 yes Figure 1 Another schematic diagram of an LED flashlight. Figure 3 yes Figure 1 A cross-sectional view of an LED flashlight.

[0040] Please see Figure 1 , Figure 2 and Figure 3 The LED flashlight in this embodiment can be configured as a downlight, such as a flashlight, a downlight for illuminating museum exhibits, a downlight for night fishing, or other miniaturized cylindrical LED flashlight devices.

[0041] Specifically, an LED flashlight may include a lamp body 10 and a light source 20, with the light source 20 disposed on the lamp body 10 for emitting light.

[0042] In this embodiment, the lamp body 10 is provided with a receiving cavity 11, and one side of the receiving cavity 11 is open. The light source 20 is disposed at the opening, so that the light emitted by the light source 20 can be emitted outside the lamp body 10.

[0043] See Figure 3 The LED flashlight may also include a cover 30 and a light-transmitting element 31. The cover 30 is connected to the lamp body 10 and is located downstream of the light source 20 in the light-emitting direction. Specifically, the cover 30 is connected to the opening side of the lamp body 10 and covers the opening. Simultaneously, the cover 30 is provided with a light-emitting channel 32, which is positioned directly opposite the light source 20, allowing the light source 20 to emit light along the light-emitting channel 32.

[0044] Furthermore, the light-transmitting element 31 is mounted on the cover 30 and located within the light-emitting channel 32, covering the light-emitting channel 32 to protect the components located inside the accommodating cavity 11. The light-transmitting element 31 can be made of transparent glass or transparent plastic, or it can be an optical lens to change the propagation path of the light emitted from the light source 20.

[0045] In this embodiment, a connecting portion 33 is provided on the side of the cover 30 opposite to the lamp body 10. The connecting portion 33 is located at the light outlet of the light outlet channel 32, allowing the light outlet channel 32 to connect a light effect accessory. The longitudinal distance from the upper surface of the connecting portion 33 to the light source 20 is fixed, maintaining a relatively short distance between the light source 20 and the light outlet, eliminating the need to change the distance between the light source 20 and the light outlet to improve light mixing uniformity. The light effect accessory can be a lens, plane mirror, color filter, or projection sheet, etc., allowing the light emitted from the light source 20 to form different light effects after passing through the light effect accessory, thus enabling the LED flashlight to meet the needs of different scenarios.

[0046] The connecting part 33 can be configured as a snap-fit ​​groove or a magnetic structure, so that the cover 30 can be detachably connected to the light effect accessory.

[0047] See Figure 3 The LED flashlight may also include a heat dissipation component 40 and a battery component 50. Both the heat dissipation component 40 and the battery component 50 are mounted on the lamp body 10 and located within the receiving cavity 11. Specifically, the heat dissipation component 40 is located between the light source 20 and the battery component 50, enabling it to dissipate heat from the light source 20. The battery component 50 is electrically connected to the light element 22 and the heat dissipation component 40 to provide power, ensuring the light emission of the light element 22 and the operation of the heat dissipation component 40.

[0048] In this embodiment, the heat dissipation component 40 may include a heat sink 41 and a cooling fan 42. The heat sink 41 is attached to the light source 20 and located between the cooling fan 42. The cooling fan 42 is located between the heat sink 41 and the battery component 50, so that the heat generated when the light source 20 emits light can be dissipated through the heat sink 41 and the cooling fan, thereby ensuring the safety of the light source 20.

[0049] Furthermore, the battery assembly 50 may include a battery 51, conductive wires 52, and a battery PCB board 53. The battery 51 is housed within a receiving cavity 11, and the battery PCB board 53 is also housed within the receiving cavity 11, located at the end of the battery 51 facing the light source 20. The conductive wires 52 connect the battery 51 and the battery PCB board 53, so that the battery PCB board 53 is electrically connected to the battery 51. In this embodiment, the battery PCB board 53 is used to regulate the power supply of the battery 51, enabling the battery assembly 50 to supply power to the light source 20 and the heat dissipation assembly 40.

[0050] It should be noted that the lamp body 10 may include a lamp head housing 12 and a battery housing 13. The lamp head housing 12 is connected to the end of the battery housing 13, so that a receiving cavity 11 is formed inside the lamp head housing 12 and the battery housing 13. Specifically, the heat dissipation assembly 40 and the light source 20 are connected inside the lamp head housing 12, and the battery assembly 50 is connected inside the 13.

[0051] In addition, the lamp head housing 12 is provided with heat dissipation holes 121 and connection holes 122. The heat dissipation holes 121 are used to dissipate heat from the heat dissipation component 40, preventing heat from accumulating inside the lamp head housing 12. The connection holes 122 are used to connect with external connectors or brackets to facilitate the installation and fixing of the LED flashlight. Specifically, in this embodiment, the connection holes 122 are threaded holes to facilitate screwing the connection holes 122 with threaded connectors on external brackets.

[0052] See Figure 2 and Figure 3 The LED flashlight may also include a control module 60 and a control box 70. The control module 60 is mounted on the lamp body 10 and located within the accommodating cavity 11. The control module 60 is electrically connected to the optical element 22 to control the brightness of the light source 20.

[0053] Meanwhile, the control box 70 is connected to the lamp body 10 and located at the end of the lamp body 10 away from the cover 30. The control box 70 contains a control box PCB board 71, a charging interface 72, and a switch button 73. The control box PCB board 71 is electrically connected to the battery assembly 50. The charging interface 72 and the switch button 73 are both connected to the control box PCB board 71. The charging interface 72 is used to charge the battery assembly 50, and the switch button 73 is used to control the light source 20 and the heat dissipation assembly 40 to turn on or off.

Figure 6 yes Figure 1 Another schematic diagram of the light source of an LED flashlight. Figure 7 yes Figure 1 Another simplified diagram of the light source of an LED flashlight. Figure 8 yes Figure 1 A further simplified schematic diagram of the light source of an LED flashlight. Figure 9 yes Figure 1 Another simplified schematic diagram of the light source of an LED flashlight.

[0055] See Figure 4 , Figure 5 and Figure 6The light source 20 may include a lamp panel 21 and a light element 22. The light element 22 is disposed on the lamp panel 21 and is capable of emitting light.

[0056] In this embodiment, multiple light elements 22 are provided on the lamp panel 21, and the multiple light elements 22 are arranged in a matrix. Furthermore, the multiple light elements 22 are rectangular in shape, such as... Figure 4 As shown. Of course, in some other embodiments, while the multiple optical elements 22 are arranged in a matrix, the shape of the multiple optical elements 22 is approximately circular, such as... Figure 6 As shown.

[0057] In this embodiment, the multiple light elements 22 may include several light emitters 23 with different light emission types. Specifically, the light emitter 23 may be an LED light-emitting chip, an LED flashlight bead, etc. Furthermore, the multiple light elements 22 may include several light emitters 23 with different light emission types. For example, one type of light emitter 23 may be a warm white LED bead, and another type may be a cool white LED bead; or one type may be a yellow light-emitting chip, and another type may be a blue light-emitting chip; or one type may be a neutral white LED bead, and another type may be a cool white LED bead, etc. This allows the light source 20 to emit light with different luminous effects after the multiple light emitters 23 emit light and after the light is mixed with different types of light emitters 23.

[0058] It should be noted that the light emission type of multiple light emitters 23 can be set to two or more, so that multiple types of light emitters 23 can mix light to obtain a light emission effect that meets the requirements.

[0059] The specific principle of light mixing is as follows: LEDs of different colors are arranged alternately on a substrate, such as warm white LEDs and cool white LEDs arranged adjacently or alternately, or red, green, and blue LEDs arranged alternately. When these LEDs of different colors emit light, different colors of light can be received evenly at all locations in space. When the human eye observes at a distance, due to the persistence of vision and spatial mixing effect, the different colors of light are superimposed and mixed on the retina, thereby forming a new color perception, thus achieving light mixing.

[0060] For ease of description, in this embodiment, one type of light emitter 23 is referred to as the first light emitter 231, and the other type of light emitter 23 is referred to as the second light emitter 232. That is, when the first light emitter 231 is set as a warm white LED, the second light emitter 232 is set as a cool white LED; or, when the first light emitter 231 is set as a yellow LED chip, the second light emitter 232 is set as a blue LED chip; or, when the first light emitter 231 is set as a neutral white LED, the second light emitter 232 is set as a cool white LED.

[0061] Multiple first light-emitting elements 231 and second light-emitting elements 232 are provided on the light panel 21.

[0062] See Figure 4 and Figure 5 In this embodiment, the number of different types of light emitters 23 in each row of light elements 22 is the same, that is, the number of first light emitters 231 and second light emitters 232 is the same in the same row; at the same time, the number of different types of light emitters 23 in each column of light elements 22 is the same, that is, the number of first light emitters 231 and second light emitters 232 is the same in the same column. Alternatively, the different types of light emitters 23 in each row of light elements 22 are arranged alternately, that is, the first light emitters 231 and second light emitters 232 are arranged alternately in the same row; at the same time, the different types of light emitters 23 in each column of light elements 22 are arranged alternately, that is, the first light emitters 231 and second light emitters 232 are arranged alternately in the same column, thereby enabling uniform light mixing among the multiple light elements 22 of the lamp board 21.

[0063] In addition, such as Figure 4 , Figure 5 and Figure 7 As shown, in the same row of optical elements 22, multiple first light emitters 231 can be arranged adjacent to each other, and multiple second light emitters 232 can be arranged adjacent to each other. Of course, in the same row of optical elements 22, the multiple first light emitters 231 and second light emitters 232 can also be arranged alternately. Similarly, in the same column, multiple first light emitters 231 can be arranged adjacent to each other, and multiple second light emitters 232 can be arranged adjacent to each other. Of course, in the same column, the multiple first light emitters 231 and second light emitters 232 can also be arranged alternately.

[0064] See Figure 5 , Figure 7 and Figure 8 Among the multiple light elements 22 on the lamp panel 21, the light-emitting bodies 23 of the same type are all centrally symmetrically distributed. That is, the first light-emitting body 231 is centrally symmetrically distributed around the center of the lamp panel 21, and the second light-emitting body 232 is also centrally symmetrically distributed around the center of the lamp panel 21, so that the light-emitting bodies 23 on the lamp panel 21 are uniformly mixed with light, thereby enabling the light source 20 to emit uniformly mixed light.

[0065] Specifically, such as Figure 5 and Figure 7 As shown, in the same row of light elements 22, light emitters 23 of the same type are arranged adjacently or at intervals. That is, in the same row, the first light emitter 231 or the second light emitter 232 can be arranged adjacently or at intervals. At the same time, in the same column of light elements 22, light emitters 23 of the same type are arranged adjacently or at intervals. That is, in the same column, the first light emitter 231 or the second light emitter 232 can be arranged adjacently or at intervals, so that the multiple light emitters 23 on the lamp panel 21 can be uniformly mixed with light.

[0066] like Figure 8 As shown, the number of light emitters 23 of the same type in each row is the same, the number of light emitters 23 of the same type in each column is the same, and the different types of light emitters 23 in each row and column are arranged alternately. That is, in the light element 22 in the same row or column, the number of first light emitters 231 and second light emitters 232 is the same, and multiple first light emitters 231 and multiple second light emitters 232 are arranged alternately, so that multiple light emitters 23 on the lamp panel 21 can mix light evenly.

[0067] like Figure 9 As shown, the number of light-emitting bodies 23 of one type in each row is different from the number of light-emitting bodies 23 of another type, the number of light-emitting bodies 23 of one type in each column is different from the number of light-emitting bodies 23 of another type, and the different types of light-emitting bodies 23 in each row and each column are arranged alternately.

[0068] Specifically, in this embodiment, the number of first light-emitting bodies 231 and second light-emitting bodies 232 are different in the same row or column, and the multiple first light-emitting bodies 231 and multiple second light-emitting bodies 232 are arranged alternately, so that the multiple light-emitting bodies 23 on the lamp panel 21 can mix light evenly.

[0069] In some other embodiments, when there are two or more types of light-emitting elements 23 among the multiple light-emitting elements 23, the light-emitting elements 23 of each type are arranged alternately in the same row or column, so that the multiple light-emitting elements 23 on the lamp panel 21 can mix light evenly.

[0070] See Figure 5 , Figure 7 and Figure 8 The light spots formed by multiple light emitters 23 of the same type are elliptical; and the light spots formed by light emitters 23 of different types are concentrically arranged, while the major axes of each light spot are set at an angle.

[0071] For ease of description, the light spot formed by multiple first light emitters 231 is designated as light spot 233, and the light spot formed by multiple second light emitters 232 is designated as light spot 234.

[0072] In this embodiment, the ratio of the major axis to the minor axis of each light spot formed by multiple light emitters 23 of different types is the same. For example... Figure 5 , Figure 7 or Figure 8 As shown, Figure 5 The ratio of the major axis to the minor axis of the light spot 233 is the same as that of the light spot 234, meaning that the shapes and sizes of the light spots 233 and 234 are identical. Of course, in practical applications, the ratio of the major axis to the minor axis of the light spot 233 can be set to be essentially the same as that of the light spot 234, meaning that the shapes and sizes of the light spots 233 and 234 are essentially the same. This ensures that the distribution of multiple first light emitters 231 and multiple second light emitters 232 on the same light panel 21 is roughly the same, thereby enabling the light elements 22 on the light panel 21 to uniformly mix light and optimize the light mixing effect.

[0073] Furthermore, among the light spots formed by multiple light emitters 23 of different types, at least two light spots have their major axes orthogonal to each other. For example... Figure 5 As shown, when there are two types of light emitters 23 in the optical element 22, the major axis of the light spot 233 formed by the plurality of first light emitters 231 is orthogonal or approximately orthogonal to the major axis of the light spot 234 formed by the plurality of second light emitters 232. Of course, in some other embodiments, when there are multiple types of light emitters 23 in the optical element 22, such as four types of light emitters 23, the major axes of the light spots formed by two types of light emitters 23 are orthogonal, and the major axes of the light spots formed by the other two types of light emitters 23 are orthogonal, so that the light spots formed by the multiple types of light emitters 23 can be uniformly mixed.

[0074] like Figure 8 and Figure 9 As shown, the multiple optical elements 22 include two types of light emitters 23, and the two types of light emitters 23 in the same row are arranged adjacent to each other, and the two types of light emitters 23 in the same column are arranged adjacent to each other. That is, the first light emitter 231 and the second light emitter 232 are arranged adjacent to each other, and the number of light emitters 23 in each row or each column can be set to 4 or 5, so that the multiple light emitters 23 form a 4x4 matrix or a 5x5 matrix.

[0075] Figure 10 yes Figure 1 A schematic diagram illustrating the control principle of the light source in an LED flashlight.

[0076] See Figure 10In this embodiment, the control module 60 is electrically connected to the optical element 22 via the PWM power drive module 61 to control the luminous brightness of different types of light emitters 23. Specifically, the control module 60 connects to the first light emitter 231 and the second light emitter 232 via the PWM power drive module 61, thereby controlling the luminous brightness of the first light emitter 231 and the second light emitter 232 respectively, thus controlling the light mixing effect of the light source 20. This allows the user to directly adjust the luminous brightness and light mixing effect via adjustment buttons. Simultaneously, because the lamp bodies of the first light emitter 231 and the second light emitter 232 are arranged adjacently or intermittently, light mixing can occur between two adjacent lamp bodies of different types, resulting in a uniform overall light mixing effect of the light source 20.

[0077] In summary, the light source 20 is mounted on the lamp body 10. The light source 20 includes a lamp panel 21 and light elements 22. The light elements 22 are mounted on the lamp panel 21 for emitting light. Multiple light elements 22 are provided, each including several light-emitting bodies 23 of different light-emitting types, and the multiple light elements 22 are arranged in a matrix. The number of different types of light-emitting bodies 23 is the same in each row of light elements 22, and the number of different types of light-emitting bodies 23 is the same in each column of light elements 22. Alternatively, the different types of light-emitting bodies 23 in each row of light elements 22 are arranged alternately, and the different types of light-emitting bodies 23 in each column of light elements 22 are arranged alternately. This allows the multiple light elements 22 arranged in a matrix to emit light, enabling light mixing between the various light-emitting bodies 23, thus ensuring the light emission effect of the light source 20. Furthermore, the light emission effect of the light source 20 can be easily adjusted by adjusting the brightness of each light-emitting body 23.

[0078] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
