Description of the invention: [Technical field of invention] A light-shaped configuration method for plant cultivation, in particular, can reduce the total height outside the package, and irradiate the planted vegetables in a close and comprehensive manner, so that the growth of light waves is intensified. Incentive control, and energy saving and reduction of the phase two degrees, and uniform light color. [Prior Art] Using the catalysis of the growth light wave, it can stimulate the growth or flowering control of leafy vegetables. Generally, the light wave used is the color of the work blue, and the light source is a diode light-emitting element, and the projection temperature is milder. It does not burn the seedlings 'using the blue wavelength of the wavelength of 46 ,, which promotes the high growth of plants, while the red light source of 670 nm is used to control the flowering period of the plants. Regarding the design of the growth of plants using diode illuminators as radicals, there are Chinese patents M323194 and M339207, which switch between different wavelengths to stimulate the light wave of different plant growth requirements and patent M294837, which changes the wavelength. In addition, there is a simulation to change the working hours to change the day and night. China's patent No. M278822, which has a flat-shaped concentrating plate, the spoke surface sequence is widely distributed with a plurality of protruding diode luminescent grains, and the surface of the concentrating plate is provided with a far-infrared conversion coating, which is converted after receiving the light wave q. Far-infrared wave 'This wavelength is suitable for biological growth; early patent No. 421993, 匕ie is an artificial light source that uses blue and red diodes in a mixed configuration to form - between the two - wavelengths to provide lions The growth requirement is that the diodes of different wavelengths are arranged in a matrix orientation, side by side or staggered in a growth box, or modulated by a driver, but the beam density is not uniform, and the color of the light is uneven. And the invention 1231852' proposes a lighting device with a hybrid light source, which is used as a plant cultivation device. It consists of a plurality of lighting modules arranged in a different arrangement by a plurality of diodes on a luminaire and receiving a control module. Different waveforms are emitted to cope with different growth characteristics of the planting and breeding, and the mixing is electrically controlled, and different lighting modules are respectively operated after different basic growth wavelengths, and are interactively projected on the plant, which is regarded as a light mixing effect. However, without the actual mixing operation, the effect beam has the same density due to the orientation of the diodes, and thus the light color of the projection surface is not 201100695. The flowering wavelength control of the plant growth wavelength is earlier. Seeing that it is a blazing bubble that uses most of the moments of the car to arrange the light wave stimulation at night, the whistling growth period, and then the design of the indoor planting plant. It _ the ride of the fluorescent tube light lamp provides a large area The ^ source' is located in the incubator's Qing, projecting a nearly uniform beam density across the plant. Because the polar body has a special object, the female 'side incubator is also used as the light source as the above-mentioned widely-made diode light-emitting element, but its angle of emergence is relatively small (as shown in the figure), so it must be in a matrix manner. A large number of diodes are arranged in a manner in which a light-emitting device u composed of a diode ball 112 is disposed in the inside of the growing box, and the diode balls 112 are distributed in a sequence matrix on the working surface of the substrate (1). The dipole crystal spheres 112 respectively project the projection angle of the total illumination angle δθ to act on the plant above the planting and destroying 12, since the total illumination angle Δ 0 is narrow, the optical path south Η must be raised. Relatively, the optical path ΔΗ of the cultivating box j is raised to a high body shape, and becomes a vertical volume form. The width W thereof is narrow, and the length of the optical path height 11 is extended, and the radiance of the total irradiation angle can obtain a large area. And the special height of the optical path is made, so that the cultivating box i occupies a space for squatting, and the beam density is difficult to be uniform, so that the color of the light is uneven, which affects the plant growth balance. SUMMARY OF THE INVENTION In order to allow a planting device, or a body such as a cultivating box, to be able to dwarf a lower height space and uniform light color, a laser chip with a blue-red light wave is used to emit a laser chip with a disk-shaped circuit board. The end is surrounded by an optically reflective curved surface to create a wide-angle tapered shape, which is convenient for reducing the total high volume space outside the box, and forming an optical mixing chamber in the axial space of the exit end surface to make the outgoing light uniform. The main object of the invention. A further object of the invention is that the reflective curved surface can be formed via a reflective inner surface. The third object of the present invention is to form an optical mixing chamber in the light projecting device, which is end-capped by a refraction, and the refractor can achieve a light wave mixing effect by waterproof protection, light wave filtering and main internal reflection. The fourth object of the present invention is that the laser element used in the laser unit is erected via the circuit board, and can be placed adjacent to the heat dissipation substrate for rapid heat dissipation. 201100695 Radiation=;===Quantity can be provided _ [Embodiment] For the detailed implementation of the present invention, please refer to the following description of the drawings: 22 Read Figure 2, the light-emitting device 2 has a heat-dissipating bottom plate 22 The periphery of the heat dissipation substrate 有 has a perforation 23 provided, and a laser is arranged on the red surface of the heat dissipation substrate 22; the laser diode 32 is arranged on the outer surface of a circuit board 31, and the circuit board 〇 (4) The two j hot bottom plate 22 is connected 'and supplied with power to the laser wafer 32 by the wire 33, : the force source 'is symmetrically reflected on the periphery of the laser unit 3 according to the disk-shaped circuit board 31. The reflective curved surface 51 can be Formed by the anti-hybrids 5, the reflections 1, σ α are integrated in the heat-dissipating bottom plate 22', and the engaging portion 41 is provided in the mouth 4 of the heat-dissipating bottom plate 22. The laser single-it 3 is distributed to the surface of the chip-shaped circuit board 31. Different wavelengths, such as red light or 'others' of the outer surface of the recording laser wafer 32, may be additionally protected by a transparent encapsulating layer 34, which is in principle a 'beam excited by Wide angle, so it will be at least -0 degree angle The illumination light f Bn ' and the laser wafer 32 located at the center of the circuit board 31, which will form at least the beam Bn of the Q 0 degree angle or the laser light located at the periphery of the circuit board 31 as shown in FIG. a day 32, which will be adjacent to the side of the surface of the reflective curved surface 51, and then (4) the first wire βι acts on the surface of the reflective curved surface 51, and has a first reverse beam from its normal line according to the curved reflection principle. The second light beam β2 emitted from the side acts on the planting tray u (shown in Fig. 3) and divides a second reflected light beam according to its normal η, the first and second reflected light beams Βίο, Β2 . The angles and flaws formed are not equal. Referring to FIG. 6 again, the reason for the above-mentioned beam emission angle is as shown in FIG. 3 to FIG. 5, and the present invention further includes a refractor 6 at the port of the reflection 枉5, and the refractor 6 is utilized. The optical axis mixing chamber 6Q is formed by the coaxial portion of the reflection 枉5 curved surface. The inner surface of the refractor 6 is a light incident surface 61, and the outer surface is an exit surface 62. The laser wafers 32 distributed on the surface of the laser unit 3 respectively excite the light beams, and independently seek the direct 201100695 line path to emit, and have different traveling directions at different angles. The initial time of the laser beam excited by the laser chip is transparent. The refraction of the sealing layer 34, and thus its exit direction, may be slightly changed by the relationship of the refracting the dense object, but the change does not affect the overall terminal illumination requirement. The filament excited from the laser wafer 32 passes through the smooth surface of the anti-alias 5 and is then emitted, and the light beam Bn passes through the light incident surface 61 provided by the refractor 6 to form a through sBt, and some of the light is incident on the light. The surface 61 reflects the reflected-reflected light beam Br, and after the reflected light beam & acts on the surface of the reflective curved surface, the equal-angle separation according to the normal line η produces a reflected beam Βη, the reflected light beam & is the same at the pointing refractor 6, and The light Bb is formed, but when it is applied to the light incident surface 61, the light beam Bn is reflected and reflected by the aliquot of its normal η, so that the single-wire Bn reflects back to the reflection via the refracting portion of the refracting mirror 6. The curved surface 51 is further reflected by the reflective curved surface 51 and directed to the refractor 6 to be refracted, and then partially reflected. Therefore, the reflective 配置5 disposed by the refractor 6 is spatially coaxial and can form a mixing chamber of light waves. 6〇, the internal mixing of the mixing chamber 6〇, the smooth surface 340, the refractor 6 and the reflective curved surface 51 form a quadrant-free internal reflection space, and the laser wafer 32 incorporated in the inner portion of the smooth surface 340 is a plurality of different wavelength planes. Co-construction, initial range is different due to matrix orientation Each of the respective beams is directed toward an angular position oriented by the mechanical structure, and substantially each of the beams is a single bundle, interacting with the reflective surface 51 and the light incident surface 61 of the refractor 6 via the action of the smooth surface 340. After reflection, the beam interferes with the interaction in most of the reflection and reflection paths; then, on the exit surface 62, the beam is uniform, and thus the light color is equal. The refractor 6 can further filter harmful light waves such as heat radiation by applying a metal film layer on the surface of the refractor 6 by means of a conductive coating. The waste heat generated by the laser unit 3 after laser irradiation via the laser wafer 32 is provided, and the tape is absorbed by the heat dissipation substrate 22, and the circuit board 31 provided on the laser unit 3 and the back surface and the heat dissipation substrate 22 are further disposed. There is a thermal conductive adhesive layer 3〇, and the thermal connection of the thermal conductive adhesive layer 3〇 enables the waste heat of the laser wafer 32 to be completely and effectively transmitted to the heat dissipation substrate 22, and the circuit board 31 to which the laser wafer 32 is attached can have higher heat conduction efficiency. The material is preferably a thin material in principle. The growth box 1 (as shown in FIG. 3) is implemented by the above-described arrangement, and since the projection angle of the light projecting device 2 is a wide angle, the optical path Δ!! is reduced, and the growing box 1 includes the planting tray 12 The upper part is provided with a height η for controlling the light-emitting device 2 and a water supply device 13. The planting tray 12 201100695 is moved in and out synchronously, and when the door is closed, the light-transmissive door panel 15 is used as an independent ring to be scaled. The 'transparent door panel 15' is transparent, and it can be controlled at night. The remaining light of 2 is used as indoor luminous illumination, and the above electromechanical device is controlled by the electric panel of the two sides of the box, and the inner surface thereof can form a reflecting surface (10), and the presence of the reflection = 14G will be The county emitted by the light projecting device 2 reflects the light edge to gather the finite light source to the center of the growing box. Referring to FIG. 7 again, the light beam exit end of the light projecting device 2 is provided with an optical lens 7 with a variable radiation angle. The lens 7 can be located at the projection end of the laser unit 3, and the axis is aligned. The sleeve 71 and the via-joint 72 are supported to be fixed in the inner portion of the light projecting device 2, and the sleeve 71 is telescopically displaceable relative to the joint holder 72, so that the distance between the lens 7 and the laser unit 3 is modulated. The shape of the projection angle changes. The sleeve 71 and the joint seat 72 can be screwed (not shown), or the inner and outer circular movement tolerances can be matched, and a generally common annular elastic stop ring can be provided between the two, and the waterproof gap can be obtained. Gas enters the laser unit. By using the above-mentioned light shape angle modulation, after concentration, it can be used as a small area after planting a small amount of light. The present invention obtains a uniform beam density for the emitted light (as shown in Fig. 8), and the human light surface 6 of the reading mirror 6 at the exit end of the mixing chamber 60 can be formed with an optical diffusing element 8, and the stray element 8 The upper surface of the mechanical reflection surface 81 'reflecting curved surface 81 and the optical curved surface 5 constituting the mixing chamber 60' causes the initial light beam on the laser wafer 32 to be reflected in the mixing chamber 6 高频 in advance, causing interference with each other. The mixing effect causes the exit surface 62 to project a uniform composite beam. The working mode is guided by the principle of reflection, and the initial beam Β〇 is emitted from the laser wafer 32 from one direction. First, after being emitted through the light surface 340, the reflective curved surface 81 is applied to the diffusing element 8, and the normal line specification of the reflecting curved surface 81 is waited for The angular reflection, the reflected light beam βΓι has a great probability of being incident on the optical curved surface 51, and the other reflected light beam Bn is reflected by the curvature specification of the optical curved surface 51, and the reflected light beam Bn is returned to the reflective curved surface 81 and then reflected by the reflective curved surface 81. Forming a re-reflected beam Bn, and the reflected beam Bn acts on the optical surface η, thus intersecting and reflecting. In the principle that the light wave is an electromagnetic wave, the beams of different wavelengths are mixed and processed by the mixing chamber 6〇. In the process, the light paths are mutually interfered to obtain the mixing effect, and the synthesized beam is emitted outside through the refractor 6 . 7 201100695 Through the operation of the thief chamber 60, the (four) wavelength laser "32 _ the excited beam is indirectly over-mixed. The internal processing of the wave chamber 60 results in a uniform synthesis wavelength. The light beam emitted from the laser wafer 32 acts on the diffusion element 8, and the diffusion element 8 is transparent. The body' and the reflective curved surface 81 are separated by light, and some of the reflection from the laser wafer is refracted from the body of the diffusing element 8. When the curvature of the curved surface of the curved surface is changed, the curvature of the curved surface is changed. The beam reflection angle will be changed to obtain the change of the light diffusion angle. Please refer to Fig. 9 again. In this case, after the beam is mixed, it is necessary to obtain a more uniform beam at the 4th age, and the correlation is in the mixing chamber 60. The end σ of the reflection 枉 5 is spaced apart from the grating 9 with a plurality of apertures 90. The one side of the grating 9 is a reflection surface 91. The reflection surface 91 and the optical surface 5 are combined to form a mixing chamber 60. The light beam generated by the laser wafer 32 is directly emitted from the light hole 9, and the reflected light beam Bri, which is partially applied to the reflective surface 9 and reflected by the reflection surface 91, may be incident on the optical curved surface 51, and the reflected light beam Bn of the optical curved surface 51 is reflected again. The reflected beam & reproduces the reflected beam & acts on the smooth surface 34〇, and is reflected by the smooth surface 340. The reflected beam Βη acts on the optical curved surface 51, and another reflected light beam Brs occurs, which has a chance to pass through the aperture 90. The light hole 90 and the reflecting surface 9 are provided one by one. The _ of the second method can be obtained by comparing the total area of the aperture 9 〇 and the reflection surface 91. If the aperture 9 〇 is larger than the reflection surface 91, the beam of the laser chip 32 can be directly emitted. If the combined area of the reflecting surface 91 is larger than that of the light hole 90, a light beam is generated by the laser wafer 32, that is, a long optical path travels in the mixing chamber 60, and the mixing probability of the mixing chamber 6 is increased. The grating 9 may be present alone or attached to the exit surface 62 of Fig. 8 to multiply the higher beam average ratio. The above description is a description of a preferred embodiment of the present invention, and the main object of the present invention is to spread at a large angle of the light source. And the mixing operation, the uniform wavelength provides the planting requirement, and the optical projection 51 of the laser unit 3 is rotated with a concentric axis to provide an optical curved surface 51, and the optical curved surface 51 is provided with a refractor 6 by the refractor 6 The light-incident surface 61 is subjected to a high-frequency reflection operation, and the light is emitted to obtain a more uniform wavelength and uniform progress, so that the performance is more soft, please ask the examiner Ming Zhong, and the advice, and please give a reasonable approval.
