[0019] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0021] See Figure 1 An embodiment of the present application provides a lamp 100, which may be a lighting lamp, a photographic lamp, a stage lamp, or other lamps.

[0022] In some embodiments, the lamp 100 includes a housing 10, a light source module 20, and a light collecting lens 30. The light source module 20 is located in the housing 10 and can be used to emit white light.

[0023] In some embodiments, the light source module 20 may include a laser assembly 210 and a wavelength conversion device 220. The laser assembly 210 is located within the housing 10 and is used to emit laser light. The wavelength conversion device 220 is located in the optical path of the laser light emitted by the laser assembly 210 and is used to convert the laser light into fluorescent light. In this way, the laser light generated by the laser assembly 210 can achieve high brightness and color saturation, and the laser light has strong directionality, which facilitates the laser light to be accurately irradiated to a specified location on the wavelength conversion device 220, facilitating precise control of the light path and focus.

[0024] In some embodiments, the wavelength conversion device 220 may be a transmissive wavelength conversion device.

[0025] In some embodiments, the wavelength conversion device 220 may be a reflective wavelength conversion device.

[0026] In some embodiments, the laser assembly 210 can be used to emit blue light, that is, the blue light can be used as laser light. The wavelength conversion device 220 can receive the blue light and convert it into red light, green light, or yellow light to be used as fluorescent light.

[0027] In some embodiments, the laser assembly 210 may include a laser 211, a scattering plate 212, and a laser collecting lens 213. The scattering plate 212 is located in the light output path of the laser 211, the laser collecting lens 213 is located in the light output path of the scattering plate 212, and the wavelength conversion device 220 is located in the light output path of the laser collecting lens 213. In this way, the scattering plate 212 helps to disperse the laser beam emitted by the laser 211, and the laser collecting lens 213 helps to focus the scattered light onto the wavelength conversion device 220, thereby reducing light loss and helping to improve the utilization rate of the laser beam emitted by the laser 211.

[0028] In some embodiments, the scattering angle of the scattering sheet 212 can be greater than or equal to 0.3 degrees and less than or equal to 10 degrees. For example, the scattering angle of the scattering sheet 212 can be 0.3 degrees, 0.5 degrees, 1 degree, 1.5 degrees, 2 degrees, 2.5 degrees, 3 degrees, 3.5 degrees, 4 degrees, 4.5 degrees, 5 degrees, 5.5 degrees, 6 degrees, 6.5 degrees, 7 degrees, 7.5 degrees, 8 degrees, 8.5 degrees, 9 degrees, 9.5 degrees, 10 degrees, or any value in between. In this way, the heat dissipation angle of the heat sink is not too large, which helps to achieve higher illumination.

[0029] In some embodiments, the laser collecting lens 213 may include one or more optical lenses located in the light output path of the scattering plate 212. In this way, the optical lens helps to improve the utilization rate of the laser beam emitted by the laser 211 and reduce light loss.

[0030] In this application, the term "plurality" means greater than or equal to two, for example, the number of optical lenses can be two, three, four, five, six or other numbers.

[0031] In some embodiments, the optical lens may be a spherical lens or an aspherical lens.

[0032] In some embodiments, a light collecting lens 30 is removably mounted within the housing 10. The light collecting lens 30 is used to collect light emitted by the light source module 20. The light collecting lens 30 is provided with a filter film 310. The filter film 310 is located in the optical path of the light emitted by the light source module 20. The filter film 310 is configured to adjust the spectral distribution of the light emitted by the light source module 20 so as to maintain the color temperature of the light emitted by the light source module 20 within a predetermined range. This allows the user to conveniently install or remove the light collecting lens 30 from the housing 10 according to personal preferences or usage requirements. For example, when the light collecting lens 30 is installed in the housing 10, the filter film 310 of the light collecting lens 30 can maintain the color temperature of the light emitted by the light source module 20 within a predetermined range, thereby helping to maintain color temperature consistency.

[0033] In some embodiments, when the primary color effect of the light source module 20 is desired, the user can install a light collecting lens without the filter film 310 in the housing 10 so that the light collecting lens does not filter the light emitted by the light source module 20. When the color temperature of the white light emitted by the light source module 20 needs to be adjusted, the user can install the light collecting lens 30 in the housing 10. Since the light collecting lens 30 is provided with the filter film 310, the filter film 310 of the light collecting lens 30 can filter the white light emitted by the light source module 20 to adjust the color temperature of the white light.

[0034] exist Figure 2 and Figure 3In an example of two different filter films 310 , when the color temperature of the light emitted from the lamp 100 is required to be approximately 9700K, the coating curve of the filter film 310 of the light collecting lens 30 can be curve one 311. The color temperature of the light emitted from the light source module 20 remains consistent after passing through the filter film 310 coated with the curve one 311. Alternatively, when the color temperature of the light emitted from the lamp 100 is required to be approximately 8500K, the coating curve of the filter film 310 of the light collecting lens 30 can be curve two 312. The color temperature of the light emitted from the light source module 20 remains consistent after passing through the filter film 310 coated with the curve two 312.

[0035] in, Figure 2 The value of the horizontal axis represents the wavelength in nm; the value of the vertical axis represents the transmittance in percentage. Figure 3 The value of the horizontal axis represents the wavelength, the unit is nm; the value of the vertical axis represents the relative radiation energy, the unit is W.

[0036] In some embodiments, the predetermined range is 9700K ± 200K, or 8500K ± 200K. For example, the predetermined range can be 8300K, 8500K, 8700K, 9500K, 9700K, 9900K, or any value between any of the aforementioned adjacent values. This facilitates the use of the lamp 100 in applications requiring consistent color temperatures of 8500K, 9700K, and so on.

[0037] In some embodiments, the filter film 310 may be located on the light incident surface of the light collecting lens 30 , or the filter film 310 may be located on the light exiting surface of the light collecting lens 30 .

[0038] In some embodiments, the filter film 310 may be coated on the light incident surface or the light emitting surface of the light collecting lens 30 .

[0039] In some embodiments, the structure for detachably mounting the light collecting lens 30 in the housing 10 can adopt an existing detachable structure. For example, the light collecting lens 30 can be detachably mounted in the housing 10 by a snap-fit structure, a magnetic structure, a threaded structure, a plug-in structure, or the like.

[0040] In some embodiments, there may be multiple light collecting lenses 30, which are arranged in sequence along the optical path of the outgoing light from the light source module 20. Each light collecting lens 30 is provided with a filter film 310, and each light collecting lens 30 is detachably mounted in the housing 10. In this way, each light collecting lens 30 can be independently detachable and replaced, making it easy for users to replace light collecting lenses 30 in different positions according to actual needs, thereby increasing the flexibility of users in replacing light collecting lenses 30.

[0041] In some embodiments, the filter films 310 of different light collecting lenses 30 are configured to adjust the spectral distribution characteristics of the light emitted by the light source module 20 to different degrees. As each light collecting lens 30 has a unique transmittance characteristic, the user can adjust the color temperature of the light emitted by the lamp 100 to different degrees by combining different light collecting lenses 30, thereby helping to improve the application scenarios of the lamp 100.

[0042] In some embodiments, the transmittance of the filter film 310 of at least one light collecting lens 30 for the first wavelength of light 41 can be higher than its transmittance for the second wavelength of light 42, and the transmittance of the filter film 310 of at least one light collecting lens 30 for the second wavelength of light 42 can be higher than its transmittance for the first wavelength of light 41. In this way, the transmittance of the filter films 310 of at least two light collecting lenses 30 for the first wavelength of light 41 and the transmittance of the second wavelength of light 42 are different, which helps maintain the consistency of the color temperature of the light emitted by the lamp 100.
