[Prior Art] The light sources used in conventional lamps are single-color temperature. In the case of street lamps, white light with high color temperature is generally used to illuminate in unrained or unfogged weather. For passers-by. There is not much problem. However, in the above-mentioned lamps, if it encounters rain or fogging weather, the white-lighted lamps will reduce the visibility of the passers-by due to insufficient penetration of the color temperature, and thus the traffic accident will easily occur. Therefore, how to conceive a kind of luminaire that can switch different color temperatures under different environmental conditions is the direction that the new model should work hard. [New content] Therefore, the purpose of the present invention is to provide a lamp that can automatically switch the color temperature. Therefore, the lamp of the present invention can automatically switch the color temperature, and comprises a casing, a lighting unit' and a sensing unit. The illuminating unit is disposed in the housing, and includes a first illuminating member respectively having different color temperatures, and a second illuminating member adjacent to the first illuminating member. The sensing unit is disposed in the housing, and includes a humidity sensor, a controller connected to the humidity sensor, and a switching module electrically connected to the light emitting unit and the controller, and the controller receives the sensing value sent by the humidity sensor And determining that a trigger signal is transmitted to the switching module, and the switching module performs switching between the first illuminating member and the second illuminating member of the illuminating unit. M412327 Preferably, the second illuminating member is disposed around the first illuminating member. Preferably, the first illuminating member of the illuminating unit is a plurality of illuminating diodes having a color temperature of 4200K to 5500K. Preferably, the second illuminating member of the illuminating unit is a plurality of illuminating two-pole ships having a color temperature of 2700K to 3000K. The effect of the novel is that the new type can be switched to use the first illuminating member or the second illuminating member to illuminate under different conditions by the setting of the sensing unit. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to FIG. 1 and FIG. 2, a preferred embodiment of the luminaire capable of automatically switching color temperature includes a housing 2, a illuminating unit 3, and a sensing unit 4. The light emitting unit 3 is disposed in the casing 2, and includes a first light emitting member 31 having different color temperatures, and a second light emitting member 32 disposed around the first light emitting member 31. In the present embodiment, 'there is a street lamp (not shown) as an illustration, and the first and second illuminating members 31, 32 are respectively composed of a plurality of light-emitting diodes, wherein the first illuminating member 31 is illuminated. The color temperature of the polar body is between 4200K and 5500K, which belongs to the white light range which is generally used for illumination. Moreover, the color temperature of the light-emitting diode of the second light-emitting element 32 is between 27〇〇κ and 3000Κ. In the environment with high rain, fog and high humidity, the red-yellow light range with better illumination is generally called red-yellow light penetration. Specifically, the first light-emitting member 31 used in the present embodiment has a color temperature of 42 〇〇 κ. The color temperature of the second illuminating member 32 is set to 2700 K, but is not limited thereto, and may be viewed separately. In the case of a demand or an actual situation, the value of the range disclosed above is changed, and the present invention is not limited. Referring to FIG. 3 and FIG. 4 , the sensing unit 4 is disposed on the housing 2 , and includes a humidity sensor 4 and a controller 42 connected to the humidity sensor 41 , and is electrically connected to the light emitting unit 3 and the controller 42 . Switching module 43. The controller 42 receives the sensing value from the humidity sensor 41 and determines that the trigger signal is transmitted to the switching module 43. At this time, the switching module 43 performs the first light-emitting component 31 and the second light-emitting component 32 of the light-emitting unit 3. Switching action between. In this embodiment, the controller 42 of the sensing unit 4 reads a predetermined humidity value, for example, 60% or 70. The predetermined humidity value can be stored in a memory connected to the controller 42 by the administrator. Not shown). The humidity sensor 41 is mainly used for detecting the humidity change of the surrounding environment, and is sent to the controller 42 for judgment. When the humidity value of the environment reaches the predetermined humidity value, the controller 42 sends a trigger signal to the switching module 43 to perform the foregoing. Switching action. In general, in the preferred embodiment, the effect of switching different color temperatures can be performed through the following scenarios: generally, the street lights have a preset starting time and the standby light is activated, and the sensing unit is connected together at this time. The sensor 1 of 4 performs the humidity measurement (S1) in the environment, and the controller 42 continuously receives the sensing value sent by the humidity sensor 41 during the detection process (S2), if the humidity in the environment is not up to the predetermined The humidity value (S21) is illuminated by the first illuminating member 31 of the illuminating unit 3 (S3) 'But when the weather is heavy (such as rain or fog), the ambient humidity gradually accumulates in the foregoing. When the humidity value is predetermined (S22)', the controller 42 sends a trigger signal to the switching module 42, and the M412327 simultaneously switches the illumination source to the second illuminating member 32 for illumination (54, S5), as previously described. Since the color temperature of the second illuminating member 32 is 27 〇〇κ, and has better penetrating power, it can provide a better line of sight for the passerby in fog or rain, and greatly reduce the visibility of the street lamp in the past due to the influence of the weather. In the event of an accident Sex. It is worth mentioning that although the lamp disclosed in the embodiment is a street lamp, it can be installed on a vehicle (not shown) as a lamp in practical applications, so that it can be used as a lamp. In the same way, the function of automatically switching the color temperature can be provided, thereby increasing the safety of the vehicle. In addition, the selection of the first and second illuminating members 31 and 32 can also be replaced by a gas lamp filled with an inert gas. Limit it. According to the setting of the sensing unit 4, the second illuminating member 32 having a lower color temperature can be automatically switched to the lower illuminating member 32 having a lower color temperature in a weather with a heavier line of rain or a dense fog such as a poor line of sight. Good penetrating power for illumination to avoid accidents due to poor line of sight. In addition, after the weather improves, switch back to the first light-emitting element 31 with a brighter color temperature, so that the design of the light source can be switched, which is not only beneficial to passers-by. By reducing the risk factors, it is indeed possible to achieve the purpose of this new type. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification made by the novel patent application scope and the novel description content, All remain within the scope of this new patent. 6 M412327 [Simple description of the diagram] Figure 1 is an architectural diagram illustrating the component architecture of the luminaire that can automatically switch color temperature; Figure 2 is a partial enlarged view of the preferred embodiment of the luminaire capable of automatically switching color temperature FIG. 3 is a top view of FIG. 2 illustrating a preferred embodiment of the luminaire capable of automatically switching color temperatures; and FIG. 4 is a schematic view illustrating a preferred embodiment of the luminaire capable of automatically switching color temperatures.
