Description

Technical Field

[0001] The present application relates to the technical field of outdoor equipment, and particularly relates to a cold light source lighting device, a lighting adjustment method, and an outdoor lighting device. Background Art

[0002] In current outdoor sports, due to the relatively dim outdoor environment, it is difficult for users to quickly find the outdoor supplies they need in the dim environment. For this reason, some manufacturers have begun to set corresponding cold light source devices on various different types of outdoor products (such as headlamps, flashlights, and knives, etc.). The cold light source device has a certain self-luminous function, and at the same time has the characteristics of less heat generation, stable lighting effect, and long service life, so as to facilitate users to quickly locate the required items in the dim environment. Currently, the cold light source devices on the market generally use two forms: coating with radium luminous coating or using tritium tubes. However, both the radium luminous coating and the tritium tube structures have certain radiation, which is likely to affect the human body; moreover, the radium luminous coating is often coated on the device, using natural light as the energy source. When the natural light is not strong and the absorption amount is insufficient, it cannot emit light stably and is easily affected by the weather, resulting in limited use scenarios outdoors.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0043] With reference to Figure 1 and Figure 2 In the first embodiment of the present application, a cold light source lighting device 100 is provided and is disposed on an outdoor lighting device. The cold light source lighting device 100 includes a fluorescent member 110 and an LED module 130; the fluorescent member 110 includes a transparent body 111 and a fluorescent layer 113. The interior of the transparent body 111 is a receiving cavity 112, and the fluorescent layer 113 is disposed in the receiving cavity 112. Phosphors are provided inside the fluorescent layer 113; the light emitting direction of the LED module 130 is set towards the fluorescent member 110; when the LED module 130 emits light towards the fluorescent member 110, the phosphors absorb light for energy storage; when the phosphors absorb sufficient light for energy storage, the phosphors reach an excited state and then emit light.

[0044] The phosphors in the fluorescent member 110 reach an excited state after absorbing sufficient light for energy storage, and can continuously and stably emit light, so that it can be used in the case of insufficient outdoor light, and the emitted light is soft and has good light efficiency; and the phosphors are dispersed and have good heat dissipation ability, which can reduce the temperature and facilitate use. When natural light is not sufficient to supplement the energy of the phosphors, the LED module 130 can be used to charge the phosphors; the light emitting direction of the LED module 130 is set towards the fluorescent member 110, which can ensure that when the LED module 130 emits light, the emitted light directly irradiates on the fluorescent member 110, so that the phosphors in the fluorescent member 110 absorb light for energy storage.

[0045] By providing the fluorescent layer 113, the phosphors can be uniformly distributed in the receiving cavity 112 of the transparent body 111; at the same time, the transparent body 111 can also cover the fluorescent layer 113 and the phosphors to prevent the phosphors from being affected by the external environment and improve the light emitting efficiency and brightness of the phosphors. That is, the phosphors inside the fluorescent layer 113 are preferably uniformly distributed. In addition, the phosphors can also be provided on the surface of the fluorescent layer 113.

[0046] The cold light source lighting device 100 of this embodiment includes a fluorescent member 110 and an LED module 130. When there is natural light, the phosphor can directly absorb the natural light for energy storage. After energy storage, the phosphor can be excited to emit light, so it can be used at night. When the natural light is insufficient, the fluorescent member 110 cannot absorb enough natural light, then the LED module 130 can be turned on to illuminate the fluorescent member 110, thereby helping the phosphor in the fluorescent member 110 to store energy. Moreover, the fluorescent layer 113 is arranged in the accommodation cavity of the transparent main body 111, which can protect the fluorescent layer 113 from external damage and ensure uniform light emission. The light emitted by the phosphor has no impact on human health, and when the environmental light is insufficient, the cold light source lighting device 100 of the present application can also charge the fluorescent member 110 through the LED module 130, and then excite the phosphor to emit light, so that the phosphor can store enough energy and make the phosphor emit light even on cloudy days and in weather with insufficient light, and the application scenarios are more extensive.

[0047] The cold light source lighting device 100 of this embodiment can be applied to various situations, especially suitable for outdoor situations. Outdoors, the phosphor in the fluorescent member 110 can absorb visible light for energy storage and then emit light. At the same time, when the energy storage of the absorbed visible light is insufficient, it can absorb the light intermittently emitted by the LED module 130, and then emit light after energy storage. The cold light source lighting device 100 can be arranged on outdoor equipment, making the outdoor equipment an outdoor lighting device. In case of insufficient light, the outdoor lighting device can be quickly located by the light emitted by the phosphor. Moreover, the phosphor has no impact on human health, improving the safety of users during use.

[0048] In some embodiments, the cold light source lighting device 100 further includes an optical sensor 150 and a controller that are electrically connected to each other. The optical sensor 150 is arranged on the outdoor lighting device, and the controller is electrically connected to the LED module 130. When the optical sensor 150 senses the environmental brightness and sends a signal, the controller receives the signal to obtain the data of the environmental brightness. When the environmental brightness is lower than the second brightness range, the controller adjusts the LED module 130 to emit light intermittently to store energy for the fluorescent member 110. When the environmental brightness is within the second brightness range, the controller adjusts the LED module 130 to turn off. The controller can control the opening and closing of the LED module 130 at the same time. The controller can be arranged on the outdoor lighting device. When the environmental brightness is lower than the second brightness range, that is, when the visibility of the environment where the user is located is lower than the second brightness range, the optical sensor 150 sends a signal, and after receiving the signal, the controller controls and adjusts the LED module 130 to emit light intermittently to store energy for the fluorescent member 110.

[0049] When the ambient brightness is within the second brightness range, the LED module 130 is turned off. At this time, the brightness of the fluorescent element 110 or natural light can already meet the requirements of the user. In this case, turning off the LED module 130 can save the energy of the LED module 130 and facilitate its subsequent use as a backup energy source for the fluorescent element 110, thereby increasing the service life of the cold light source lighting device 100 outdoors and improving the outdoor survival rate of the user.

[0050] In the case where a stronger light effect is required, that is, for road lighting, the phosphor is preferably a combination of yellow phosphor and a small amount of green phosphor, with a mass ratio preferably of (5 - 10):1, and the particle size of the phosphor is preferably 15 - 25 μm; the yellow phosphor is a phosphor coated with alumina or silica; at this time, the LED chip of the LED module 130 is preferably a blue LED chip.

[0051] In the case where the ambient temperature is high and the device is required to have high stability and a long service life, the phosphor is preferably a combination of yellow phosphor and infrared phosphor, with a mass ratio preferably of (3 - 10):1, the particle size of the phosphor is preferably 25 - 30 μm, and the yellow phosphor is a phosphor coated with alumina or silica; at this time, the LED chip of the LED module 130 is preferably a UV LED chip (i.e., a purple LED chip).

[0052] In the case of rescue and warning, the phosphor is preferably a red phosphor, with a particle size preferably of 5 - 10 μm; at this time, the LED chip of the LED module 130 is preferably a UV LED chip.

[0053] In the case where concealment is required, such as for outdoor security, etc., the phosphor is preferably a near-infrared phosphor, with a particle size preferably less than 50 nm; at this time, the LED chip of the LED module 130 is preferably an infrared LED chip.

[0054] In the case where the ambient humidity is high, the phosphor is preferably a combination of yellow phosphor, green phosphor and red phosphor, and the ratio of the three is preferably (1 - 4):(1 - 4):1. The yellow phosphor is a yellow phosphor coated with alumina or silica, with a particle size preferably of 5 - 15 μm; at this time, the LED chip of the LED module 130 is preferably a blue LED chip.

[0055] The thickness of the phosphor can be set according to actual needs, preferably 10 - 100 μm, to prevent heat concentration during light emission caused by excessive stacking of the phosphor while ensuring uniform distribution of the phosphor, thereby extending the service life of the cold light source lighting device 100.

[0056] In some embodiments, the LED module 130 includes a plurality of LED chips, and the LED chips include UV LED chips.

[0057] That is, the use situation, stability, and service life factors of the cold light source lighting device 100 in high-temperature weather are given priority. The phosphor is energized by the UV lamp core. The phosphor is preferably a combination of yellow phosphor and infrared phosphor or red phosphor, which can emit strong brightness outdoors and has a strong reminder effect. Specifically, all the LED lamp cores can be UV lamp cores, or can be set as a combination of multiple lamp cores including UV lamp cores according to needs.

[0058] Combined with reference Figure 3 , in some embodiments, a plurality of protrusions are provided on the surface of the phosphor layer 113, and the cross-sectional width of the protrusions decreases in the direction away from the phosphor layer 113. By providing a plurality of protrusions, phosphor accumulation can be prevented, ensuring that the phosphor is evenly distributed, and preventing the phosphor from moving, thereby improving the light efficiency and stability.

[0059] Specifically, the phosphor member 110 can be a groove structure with a lower middle and higher ends, so that the light emitted by the phosphor therein can be concentrated in the direction of its central axis, thereby increasing the luminous intensity and further achieving a better reminder effect.

[0060] In some embodiments, a plurality of transparent protrusions 114 are provided between the bottom of the phosphor layer 113 and the transparent main body 111; phosphors are provided between adjacent transparent protrusions 114.

[0061] By arranging the phosphor layer 113 at the central position of the transparent main body 111 through the transparent protrusions 114, it is convenient for the light emitted by the phosphor to be emitted from the central position, improving the light efficiency and luminous intensity; in addition, phosphors are also provided between the transparent protrusions 114, so that the phosphors are evenly arranged in the accommodation cavity 112 of the transparent main body 111.

[0062] A heat sink or heat dissipation powder can also be provided between adjacent transparent protrusions 114. The heat sink or heat dissipation powder is used for the heat dissipation of the phosphor. When the phosphor enters the excited state and emits light, as the use time prolongs, the temperature will gradually rise. The setting of the heat sink or heat dissipation powder can reduce the temperature of the phosphor and the overall temperature in the accommodation cavity 112, thereby prolonging the service life of the phosphor. Specifically, a heat sink can also be provided on the surface of the phosphor layer 113 to further improve the heat dissipation effect.

[0063] The number of the transparent protrusions 114 can be set according to actual needs. Specifically, it needs to be set on the premise of satisfying the uniform distribution of the phosphor.

[0064] Combined with reference Figure 4 and Figure 5 , in some embodiments, a filter 120 is provided between the LED module 130 and the phosphor member 110; a base 140 is provided at the bottom of the LED module 130.

[0065] The filter 120 is used to prevent light leakage during the process of the LED module 130 energizing the phosphor during intermittent light emission, and improve the utilization rate of the light absorbed by the phosphor by the LED module 130. When the cold light source lighting device 100 is applied to equipment that requires high concealment, if light leakage occurs in the LED module 130, it will cause the position of the user to be exposed, resulting in the inability to meet the concealment requirements. The setting of the filter 120 can reduce or effectively prevent the occurrence of light leakage. The base 140 is used for fixing the LED module 130. The cold light source lighting device 100 can be stably connected to the outdoor lighting device through the base 140, so that the position of the outdoor lighting device can be quickly located through the cold light source lighting device 100 when the visibility outdoors is low.

[0066] Combined with reference Figure 6 , the second embodiment of the present application provides a light emission adjustment method using the cold light source lighting device 100 described in the first embodiment or any one of its implementation manners, including the following steps:

[0067] S1: Collect the current ambient brightness data through the optical sensor 150, and send the data to the controller for analysis and processing.

[0068] A first brightness range, a second brightness range, and a limited brightness time period are preset in the controller, and the highest value of the second brightness range is less than or equal to the highest value of the first brightness range.

[0069] The first brightness range includes the second brightness range, and the first brightness range and the second brightness range can be set according to actual needs, specifically according to the actual application scenario of the cold light source lighting device 100.

[0070] S11: When the ambient brightness is lower than the lowest value of the first brightness range, the controller determines whether the ambient brightness belongs to the second brightness range.

[0071] S111: When the ambient brightness is lower than the lowest value of the second brightness range, the controller controls the LED module 130 to emit light intermittently according to the trigger signal from the optical sensor 150, and performs energy storage processing on the fluorescent member 110.

[0072] When the ambient light is insufficient, the phosphor will slowly release the stored energy to emit light. Therefore, when the ambient brightness is lower than the lowest value of the second brightness range, the light emitted by the fluorescent member 110 is obviously not sufficient to play a good reminder role; at this time, the LED module 130 emits light intermittently, which can not only store energy for the fluorescent member 110, but also play a reminder role, facilitating the user or others to locate the position of the cold light source lighting device 100.

[0073] In some embodiments, when determining whether the ambient brightness belongs to the second brightness range, it further includes: S112: When the ambient brightness belongs to the second brightness range, the controller starts the timing module and enters the determination of the brightness persistence within the defined brightness time period.

[0074] Specifically, the defined time period is longer than an intermittent period of the intermittent light emission of the LED module 130. Therefore, it is possible to judge whether the cold light source lighting device 100 can emit light stably by the change of the ambient brightness within the defined time period.

[0075] S1121: When the ambient brightness remains within the second brightness range throughout the defined time period, the controller receives the hold signal of the optical sensor 150 and controls the LED module 130 to turn off.

[0076] At this time, the phosphor has absorbed enough energy and can emit light with sufficient intensity during the interval when the LED module 130 is not emitting light, so that the ambient brightness belongs to the second brightness range within the defined time period. Therefore, the LED module 130 can be turned off to reduce the power consumption of the LED module 130.

[0077] In some embodiments, when determining the brightness persistence within the defined brightness time period, it further includes: S1122: Within the defined brightness time period, when the ambient brightness cannot be maintained within the second brightness range, the controller adjusts the LED module 130 to continuously emit light intermittently.

[0078] At this time, the phosphor has not absorbed enough energy and cannot emit light with a brightness belonging to the second brightness range, so that the ambient brightness cannot continuously belong to the second brightness range within the defined time period. The LED module 130 continues to be in the intermittent light emission state, so as to store energy for the phosphor in the fluorescent member 110 through the LED module 130. Therefore, at this time, the cold light source lighting device 100 mainly plays a positioning and reminder role for the cold light source lighting device 100 through the LED module 130.

[0079] S113: When the ambient brightness is higher than the maximum value of the second brightness range, control the LED module 130 to turn off. At this time, the natural light or the light emitted by the fluorescent member 110 already meets the user's requirements.

[0080] S12: When the collected ambient brightness is greater than the maximum value of the first brightness range, the controller determines that the light is sufficient and terminates the current operation of the cold light source lighting device 100 without performing the next operation.

[0081] When the ambient brightness is higher than the set first brightness range, the brightness of the environment is sufficient for the user to see the items clearly, and there is no need to energize the phosphor in the fluorescent member 110. The phosphor directly stores energy by absorbing the ambient light, which can improve the energy utilization rate.

[0082] The light emission adjustment method of the cold light source light emitting device 100 in this embodiment can utilize the cold light source light emitting device 100 to perform light emission adjustment, so that the cold light source light emitting device 100 can stably emit light under low ambient brightness, thereby playing a role of positioning and reminder through the cold light source light emitting device 100; and through the setting of the first brightness range, the second brightness range and the limited time period, the LED module 130 of the cold light source light emitting device 100 can be further regulated, enabling the phosphor to stably emit light under specific conditions, saving the energy consumption of the LED module 130, and extending the service life of the LED module 130 and the cold light source light emitting device 100.

[0083] Combined with reference Figure 7 , the third embodiment of the present application provides an outdoor lighting device, including an outdoor device main body 200 and the cold light source light emitting device 100 as described in the first embodiment or any one of its implementation manners, and the cold light source light emitting device 100 is arranged on the outdoor device main body 200.

[0084] The outdoor lighting device in this embodiment is provided with the cold light source light emitting device 100 on the outdoor device main body 200. The outdoor device main body 200 itself does not emit light or cannot emit light according to the ambient brightness; therefore, in the case of low ambient brightness, through the light emitting characteristics of the cold light source light emitting device 100, the outdoor lighting device can be positioned and reminded, facilitating the user to find the outdoor device main body 200 they need.

[0085] In some implementation manners, the cold light source light emitting device 100 is arranged inside the outdoor device main body 200, and a slot 160 corresponding to the fluorescent member 110 is arranged on the outdoor device main body 200. The fluorescent member 110 of the cold light source light emitting device 100 faces the slot 160, and can emit light through the slot 160, thereby performing positioning and reminder.

[0086] The cold light source light emitting device 100 is arranged inside the outdoor device main body 200, and the fluorescent member 110 faces the slot 160, and can emit light through the slot 160; moreover, the outdoor device main body 200 can protect the cold light source light emitting device 100 from being damaged by the outside. There can be several slots 160, and their shapes and sizes are not limited, mainly used to let the light emitted by the cold light source light emitting device 100 pass through, so as to achieve the role of positioning and reminder through the emitted light. Specifically, the cross-section of the slot 160 can be rectangular, square, oval, circular, star-shaped, etc.

[0087] The optical sensor 150 is preferably disposed on the surface of the outdoor device main body 200, or a slot corresponding to the optical sensor 150 is provided on the outdoor device main body 200, and the optical sensor 150 is disposed inside the outdoor device main body 200 and is opposite to the central axis position of the light emitting direction of the fluorescent member 110 through the slot, facilitating the optical sensor 150 to sense the light emitting intensity of the fluorescent member 110.

[0088] In summary, the present application provides a cold light source light emitting device, a light emitting adjustment method, and an outdoor light emitting device. The cold light source light emitting device includes a fluorescent member and an LED module. When there is natural light, the phosphor can directly absorb the natural light for energy storage, and after energy storage, the phosphor can be excited to emit light for use at night. When the natural light is insufficient, the fluorescent member cannot absorb enough natural light, and then the LED module can be turned on to irradiate the fluorescent member to help the phosphor in the fluorescent member store energy. Moreover, the fluorescent layer is disposed in the accommodation cavity of the transparent main body, which can protect the fluorescent layer from external damage and ensure uniform light emission. The light emitted by the phosphor has no impact on human health, and when the environmental light is insufficient, the cold light source light emitting device of the present application can also charge the fluorescent member through the LED module, and then excite the phosphor to emit light, so that the phosphor can store enough energy and emit light even on cloudy days and in weather with insufficient light, and the application scenario is more extensive.

[0089] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application and are not intended to limit them. Although the present application has been described in detail with reference to the foregoing examples, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing examples or perform equivalent replacements for some of the technical features. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the examples of the present application.
