As shown in fig. 1, the outdoor optical fiber type lighting lamp includes a light source assembly, a mainoptical fiber 100, anoptical fiber splitter 200, suboptical fibers 300, anoptical system 500, and a light-emitting plate 600, wherein the light source assembly includes alight source 700 and a secondaryoptical system 800, thelight source 700 is connected to the mainoptical fiber 100 through the secondaryoptical system 800, light from thelight source 700 is transmitted to the mainoptical fiber 100 through the light-condensing effect of the secondaryoptical system 800, and light entering the mainoptical fiber 100 is distributed to a plurality of suboptical fibers 300 through theoptical fiber splitter 200. Theoptical system 500 includes a plurality of optical units, and thesub-fibers 300 extend into the respective optical units. The optical units are provided with light reflecting members, and the light transmitted to the corresponding optical units by thesub-fibers 300 is reflected to the light-emitting plate by the light reflecting members and finally transmitted from the light-emittingplate 600.

In the illumination lamp of the present invention, the optical component may be areflective cup 510. The reflecting cup belongs to one kind of reflecting device, and utilizes limited light energy to control the illumination distance and the illumination area of the main light spot through the light reflector. The reflecting cup can be divided into a metal reflecting cup, a plastic reflecting cup and a glass reflecting cup according to the material, and the metal reflecting cup has the advantages of deformation memory, low cost, temperature resistance and the like, so the metal reflecting cup is preferably used in the invention.

The reflecting mirror can be divided into a plane reflecting mirror, a spherical reflecting mirror and an aspheric reflecting mirror according to the shapes. The invention can select the type of the reflector according to the requirement of lighting effect.
Thelight source 700 may be an incandescent lamp, a fluorescent lamp, or an LED lamp. Thelight source 700 is preferably an LED lamp because of its advantages of small size, low power consumption, long life, high brightness, low heat, and robustness. When the LED lamp is used as a light source, the brightness of the illumination lamp can also be controlled by adjusting the color temperature of the light source. In order to conveniently adjust the color temperature of the outdoor optical fiber type illuminating lamp, acontrol box 900 may be connected to the illuminating lamp, and a component capable of adjusting the brightness and the color temperature of the light source is disposed on thecontrol box 900. The brightness and color temperature of thelight source 700 can be adjusted continuously or in steps. As shown in fig. 1, acontrol box 900 is connected to the illumination lamp, and the color temperature and brightness of the outdoor optical fiber illumination lamp can be adjusted by thecontrol box 900. For example, a color temperature adjusting button is provided on thecontrol box 900, and by operating the color temperature button, a control circuit connected to the color temperature adjusting button adjusts the light emitting brightness of the LED chip. The light source is set to be an LED chip combination with different color temperatures, such as a cold white LED chip and a warm white LED chip combination or an RGB LED chip and a white LED chip combination, and the color temperature is continuously adjusted by mixing the brightness of the cold white LED chip and the brightness of the warm white LED chip or the brightness of the RGB LED chip and the brightness of the white LED chip to obtain the color temperature with any required value.
For the more convenient of colour temperature regulation, still be provided with 5 shelves colour temperature pilot lamps on thecontrol box 900, the colour temperature value that the colour temperature pilot lamp instructed respectively is: 3000K, 4000K, 4500K, 5500K and 6000K. The five-gear color temperature values are common color temperatures, the color temperature of the numerical value can be obtained by operating the indicator lamp, and the color temperature can be quickly adjusted by one-key operation. After the color temperature is fixed, the brightness of the outdoor optical fiber type illuminating lamp can be adjusted to meet the illumination brightness requirements of different conditions. Thecontrol box 900 is provided with a brightness control button, and the brightness control button is operated to adjust the illumination brightness of the outdoor optical fiber type illuminating lamp without changing the ratio of the cold white LED chip illumination brightness to the warm white LED chip brightness or the ratio of the RGB LED chip brightness to the white LED chip brightness. Similarly, in order to realize rapid adjustment of the brightness, an 8-gear brightness indicator lamp is further disposed on thecontrol box 900, and the brightness can reach 100% at most and 30% at least with reference to the rated current of the LED chip. Through the operation the luminance instructs the button, realizes dividing the gear of outdoor optic fibre formula light luminance and adjusts to the luminance of outdoor optic fibre formula light is adjusted to accurate regulation.
When thelight source 700 starts to work, the generated heat will affect the service life of the light source if not dissipated in time. Therefore, in the present invention, aheat dissipation system 1000 is connected to thelight source 700 to dissipate the heat dissipated by the LEDs as soon as possible.
In the outdoor optical fiber type illumination lamp of the present invention, the mainoptical fiber 100 and the suboptical fiber 300 are multimode optical fibers. The diameter of the fiber core of the multimode fiber is relatively large, the multimode fiber can transmit light in multiple modes, the incident light has multiple angles entering the fiber core, and the forward propagation path is also multiple. The optical fiber can be divided into ultraviolet optical fiber, observable optical fiber, near infrared optical fiber and infrared optical fiber from the working wavelength, the illuminating light is visible light, and the optical fiber used by the illuminating lamp is the observable optical fiber. The optical fiber in the refractive index distribution is commonly a step-type optical fiber, a near-step-type optical fiber, or a graded-index optical fiber. The optical fiber is made of quartz glass, and has the advantages of low cost, good light transmission and convenience in processing.
When a soft lighting requirement is required, thelight emitting panel 600 may select a light diffusion panel having a diffuse transmission effect on light. The diffusion particles with light interference are added into the light diffusion plate, so that multiple refraction of light is realized due to different refractive indexes when the light passes through the base material, the light is uniformly dispersed, reflected and scattered, the direction of light transmission is adjusted, the point light source is changed into a surface light source, and the light is softer and free of glare due to loss of part of light. An acrylic plate or a PC plate may be optionally used as the light diffusion plate. The acrylic light diffusion plate is prepared by taking polymethyl methacrylate as a base material and adding a diffusing agent; the PC light diffusion plate is an optical PC endurance plate made of polycarbonate as a base material and a diffusing agent.
The outline of thelight extraction panel 600 may be designed in any shape, such as a regular geometric shape like a circle, a square, a triangle, a prism, or an irregular shape as shown in fig. 2. The light emitting surface of the light emitting plate can be a plane, and can also be designed into a non-plane with high and low fluctuation so as to form various three-dimensional shapes. For example, when the lighting lamp is placed in an elegant environment, the light-emitting surface of the light-emitting plate can be designed to have an artistic three-dimensional shape such as a rockery. The light-emitting surface of the light-emitting plate can be pasted with a light filter so as to transmit light with different colors according to requirements.
The outdoor optical fiber type illuminating lamp further comprises ahousing 400, and the optical unit is positioned in thehousing 400. As shown in fig. 1, thehousing 400 surrounds the optical unit, and the lower end portion thereof is connected to thelight emitting plate 600 to protect the optical unit. A hole for receiving the suboptical fiber 300 therethrough is provided on the housing so that the suboptical fiber 300 can protrude into the optical unit through the housing. Thehousing 400 is preferably made of an opaque material so that light entering the optical unit can be further prevented from being lost by transmission.
In the outdoor optical fiber type illumination lamp of the present invention, thehousing 400 is detachably connected to thelight emitting plate 600, such as by a screw connection or a snap connection. The threaded connection is a detachable fixed connection which is widely used, and has the advantages of simple structure, reliable connection, convenient assembly and disassembly and the like. The screw connection is to screw a screw directly into the screw holes of the lens module and thelight emitting panel 400, so as to achieve the effect of tightly connecting the lens module and thelight emitting panel 400. The snap connection is classified into a cantilever type snap connection (as shown in fig. 3), a cylinder type snap connection (as shown in fig. 4), and a ball type snap connection (as shown in fig. 5). When the lens module and thelight emitting panel 400 are connected by using a snap, the snap connection may be a cantilever type snap connection or a cylindrical type snap connection.
