BACKGROUND
Technical Field
[0001] The present utility model relates to the field of lighting technologies, and more specifically, to a light source system and a lighting system.
Related Art
[0002] A light emitting diode (LED) is a semiconductor solid light source that can directly convert electricity into visible light, and compared with a conventional light source, has advantages of long life, high light efficiency, no radiation, and low power consumption. With exacerbation of problems plaguing the world in recent years, such as energy shortage and climate warming, semiconductor LED light sources are becoming more universally applied to various fields, and quite tend to replace conventional light sources.
[0003] For a current technology, in a normal working state, a maximum luminous flux of a single LED chip (with a size of 1 mm × 1 mm) does not exceed 300 lumina (lm). For some light source systems that require a relatively high luminous flux output, an LED array may be used for implementation. However, if a luminous flux output of a light source system is required to reach that of a conventional halogen lamp (1200 W to 1500 W), a quantity of LED chips of the LED array is required to be very large, consequently causing the light source system to have a very large volume and therefore fail to be applicable to some application occasions. For example, if a luminous flux output of a stage light device using an LED array needs to reach that of the a conventional halogen lamp (1200 W to 1500 W), a volume of the stage light device is far beyond an acceptance range of a user, and consequently the stage light device cannot be used.
[0004] In the prior art, a laser diode (LD) has brightness that is far higher than that of an LED. Therefore, a light source system using an LD can not only have a high luminous flux output, but also have a volume that is effectively controlled. However, currently among LDs with various colors, even costs of a cheapest blue LD are far higher than that of an LED, and costs of a green LD or a red LD are far higher than that of the blue LD. Output light in an existing light source system has relatively weak green and red components and therefore needs to be enhanced. Therefore, if an LED is replaced with an LD to increase a luminous flux output of the light source system, extraordinarily expensive green and red LDs often need to be used, consequently causing costs of the light source system to be considerably increased. Therefore, in the prior art, when the light source system has a relatively high luminous flux output, a volume and costs of the light source system cannot be effectively controlled.
[0005] Another example of the prior art can be seen in document CN 102 662 301 A, which discloses a light source system according to the preamble of claim 1. Documents CN 104 456 429 A, CN 104 110 651 A and US 2012/147601 A1 also represent prior art relevant to the present invention.

[0021] As described in the related art, in the prior art, when the light source system has a relatively high luminous flux output, a volume and costs of the light source system cannot be effectively controlled.
[0022] Based on this, the embodiments of this application provide a light source system and a lighting apparatus, and mix an LED array and a laser light source array, to complement light emission of the LED array, increase a luminous flux output, and effectively control a volume and costs of the light source system.

To achieve the foregoing objective, the technical solutions provided in the embodiments of this application are as follows. Specifically, the technical solutions provided in the embodiments of this application are described in detail with reference to FIG. 1 to FIG. 4.

[0024] It should be noted that, by using a controller electrically connected to the laser light source array, the light source system provided in this embodiment of this application may further control the laser light source array to be switched on or off and control current intensity of the laser light source array, to control the first light-emitting subsystem to be switched on or off and adjust light source intensity of the first light-emitting subsystem.
[0025] According to the light source system provided in this embodiment of this application, laser light emitted by a laser light source is incident into the wavelength conversion apparatus; the wavelength conversion area of the wavelength conversion apparatus emits exciting light after being excited by the laser light; after passing through the first light transmitting hole, the exciting light is combined with light emitted by the first LED array and then incident into the light source shaping subsystem; combined light is first incident into the integration lens group, and after the integration lens group homogenizes the incident light, the incident light is output to the first condensing lens, and passing through the first condensing lens. When output light with a small light spot needs to be output from the light source system, the moveable optical block may be moved into the output light path of the first condensing lens, and the output light of the first condensing lens may be further converged by the moveable optical block and then output. In this case, not only light can be output with a small light spot, but also a light beam effect can be produced.

This needs to be designed based on actual application, and is not specifically limited in this embodiment of this application.
[0027] In addition, in the light source system in this embodiment of this application, light emission colors of a single laser light source of the laser light source array and a single LED chip of the first LED array are not specifically limited, and specific design needs to be performed based on colors of light that needs to be emitted by the first light-emitting subsystem and light that needs to be emitted by the light source system.

When the first light-emitting subsystem is required to emit white light, the laser light source array may be set to a blue light laser light source array, and a wavelength conversion area of the wavelength conversion apparatus may be set to a yellow Phosphor area; or the laser light source array may be set to ultraviolet laser light source array, and a wavelength conversion area of the wavelength conversion apparatus may be set to a green Phosphor area. When the light source system is required to emit white light, the laser light source array may be used to excite the wavelength conversion apparatus to emit exciting light of any color of red, green and blue, and the first LED array emits light of the other two colors. Then, the light of the three colors is combined to generate the white light.
[0028] The wavelength conversion apparatus in the embodiment shown in FIG. 1 is a wavelength conversion apparatus of a light transmitting type. The wavelength conversion apparatus provided in this embodiment of this application may further be a wavelength conversion apparatus of a reflection type.

[0029] In addition, to further improve the light emergence effect, the first light-emitting subsystem provided in this embodiment of this application further includes:
a first collimating lens 15 that is disposed on the light-emitting light path of the laser light source 111 and is located between the laser light source 111 and the reflector 13; and
a second condensing lens 16 disposed between the wavelength conversion apparatus 12 and the color separation apparatus 14.
[0030] Specifically, according to the first light-emitting subsystem shown in FIG. 2 in this embodiment of this application, laser light emitted by a laser light source is output to a reflector corresponding to the laser light source. The reflector reflects the output laser light to the color separation apparatus. The color separation apparatus may be a dichroic filter. The color separation apparatus is set to be capable of reflecting laser light of a color emitted by the laser light source, and transmitting exciting light of another color emitted by the wavelength conversion area after the wavelength conversion area is excited by the laser light; and therefore color separation is performed by using the color separation apparatus, to make the exciting light output to the first light transmitting hole.

A circuit board of the first LED array provided in this embodiment of this application may be a copper board or a board of another material. This is not specifically limited in this embodiment of this application.
[0032] In addition, to improve a heat dissipation effect of the light source system, referring to FIG. 3, FIG. 3 is a schematic structural diagram of a second light-emitting subsystem according to an embodiment of this application. The second light-emitting subsystem provided in this embodiment of this application further includes:
a heat pipe substrate 22 that is disposed on the back of the first LED array 21 and is located between the first LED array 21 and the first light-emitting subsystem, where the first light transmitting hole 211 penetrates the heat pipe substrate 22, and a quantity of heat pipes on the heat pipe substrate is not specifically limited in this embodiment of this application.
[0033] In addition, an embodiment of this application further provides another light source system. Specifically referring to FIG. 4, FIG. 4 is a schematic structural diagram of another light source system according to an embodiment of this application.

[0035] Specifically, an example in which the light source system needs to emit white light is used. The first LED array, the second LED array, and the third LED array emit light of different colors, which are respectively any one of red, green, and blue. In addition, the exciting light emitted by the wavelength conversion apparatus after the wavelength conversion apparatus is excited by the laser light source array has a color that is the same as that of the light emitted by the first LED array, thereby preventing the light combination apparatus from filtering the exciting light. Alternatively, the exciting light emitted by the wavelength conversion apparatus after the wavelength conversion apparatus is excited by the laser light source array is white light. Preferably, the first LED array emits green light, the laser light source array emits blue light or ultraviolet or near ultraviolet laser light, and green Phosphor is set on the wavelength conversion apparatus, so that green light emitted from a first light-emitting subsystem can be obtained.
[0036] Further, to ensure that exciting light passes through the light combination apparatus without a loss, referring to FIG. 4, the light combination apparatus provides in this embodiment of this application further includes a second light transmitting hole 253 that allows light to pass through and that coincides with the output light path of the wavelength conversion apparatus 12.
