New description: [New technical field] This creation is about lighting fixtures, especially for lighting fixtures with a one-piece reflector housing. [Prior Art] Lighting fixtures, mobile devices, plasma display panels, and LCD TVs are capable of emitting visible light and have functions such as surrounding the casing, transmitting optical signals, or reflecting light images. Φ These machines usually have a reflector that reflects light to the reflector to increase the brightness of the light or change the direction of the light. Therefore, in order to prevent the light from being reflected to the reflecting plate, the amount of light is lowered, and the surface of the reflecting plate is required to have a high reflectance of visible light. Heretofore, as a means for improving the reflectance of the surface of the reflecting plate, a metal is polished to be a mirror surface or a white paint having a high reflectance is applied. Please refer to Figure 1, which is a general traditional lighting fixture iOO. It is mainly disposed on the light source carrier 130 having the accommodating space 120, and is provided with a corresponding two-clamp and the reflective plate 110 is embedded therein, and the reflection plate 110 is used to change the light transmitted through the reflection plate 110 to change the light. The direction of travel further increases the brightness of the luminaire 100. However, since the luminaire 100 made in this form is required to manually mount the reflector 110 in the luminaire 10', it is time consuming and labor-intensive and relatively labor-intensively increases the process cost. No. 7,416,774, entitled "Precoated metal sheet for light reflectors". The patent provides a reflecting plate having high diffusion and high reflectivity in visible light, which pre-coats the reflective film on one side of the metal plate or one side of the plated metal plate at a wavelength of 4 〇〇 mn 3 The reflectance under visible light of M410173 to 700 nm reaches 70°/❶ or more. This patent utilizes coating techniques and materials to provide visible light reflections with increased light utilization, but this technique increases process steps and increases process cost. In addition, reference is made to U.S. Patent No. 7,413,799, entitled "Reflective film and reflective plate", which utilizes a resin having a reflectance of less than 1.52 and a titanium dioxide having a reflectance of 2.5 to form a reflective film. And coated on the substrate to form a reflecting plate, which can reflect more than 95% of the light source at a wavelength of 550 nm. However, the fabrication of the reflector requires a process of coating the reflective film after the reflective substrate is formed, thereby increasing the cost of the product. In view of this, the creators of this creation carefully studied and proposed the lighting fixtures made by integrally forming the reflector lamp housing. The present invention discloses that a composite material having high reflectivity directly forms a lamp housing and a lighting fixture having high reflectivity, which can solve the problem that a conventional reflector needs to be coated with a reflective layer, thereby reducing the cost and time of the process. [New content] The main purpose of this creation is to provide an illumination lamp made by integrally forming a reflector lamp shell. By integrally forming a high-reflectance reflector lamp shell, the steps of the lamp manufacturing process are reduced and the illumination brightness of the lamp is improved. A secondary objective of the present invention is to provide an integrally formed reflector lamp housing that utilizes a composite material to be moved into a reflector lamp housing, which has the effect of reflecting visible light, thereby reducing reflection reversal steps and reducing process costs. In order to achieve the above-mentioned main purpose, the present invention proposes a lighting fixture manufactured by integrally forming a reflector lamp housing, which mainly comprises: a reflector lamp housing and at least a lamp source. Reflection M410173 lamp housing has a reflective surface and is made of composite material. The composite material consists of a plastic material and an organic modified reflective material. The light source device is disposed in the reflector lamp housing, and the light emitted by the lamp source is reflected by the reflective surface of the reflector lamp to be illuminated. In order to achieve the above secondary purpose, the present invention proposes a reflector lamp shell which is integrally formed by a composite material, and the reflector lamp shell has a high reflection curved surface for reflecting light emitted by a light source in a lighting fixture, and its characteristics. The composite material consists of a plastic material and an organic modified reflective material. The above and other objects, features, and advantages of the present invention will become more apparent and understood. [Embodiment] Although the present invention can be embodied in different forms, the embodiments shown in the drawings and the following description are preferred embodiments of the present invention, and it is understood that One example of creation is 'and is not intended to limit the present creation to the drawings and/or the particular embodiments described. Referring to FIG. 2, it is a lighting fixture 200' disclosed in the first embodiment of the present invention, which mainly comprises: a reflector lamp housing 21〇 and at least one lamp source 220. The reflector lamp housing 210 has a reflective curved surface and is integrally formed by a composite material. The light source 22 is powered by a power terminal 230, and the emitted light is reflected by the reflective surface of the reflector lamp housing 210. The composite material is composed of a plastic material and an organically modified reflective material. Please refer to FIG. 3 , which is a lighting fixture disclosed in the second embodiment of the present invention. 5 M410173 mainly comprises: a reflector lamp shell 310 and at least A light source no. The reflector lamp housing 3l has a reflective curved surface and is integrally formed by a composite material. The light source 32 turns, and the emitted light reflects light through the curved surface of the reflecting lamp housing 210. The composite material is composed of a plastic material and an organic modified reflective material. The light source 220, 320 used for the lighting fixture is used as the light source of the lighting fixture 200, 300. The light source can be selected from the group consisting of a tungsten filament lamp, a quartz halogen lamp, an incandescent lamp, a fluorescent lamp tube, a mercury cathode lamp cold cathode tube, a wide rainbow lamp, and a fluorescent lamp. And one of the lighting diodes (LEDs). The light source 220, 320 can be placed around the reflector housing 310 to provide an additional source of light for the reflector housing 310. For example, the lighting fixture can be used as a backlight module, that is, the light source 220, 320 can be a cold cathode tube or a light emitting diode (LED). In addition to the above-mentioned light source, any element having illuminating characteristics can also be used as the light source 220, 320 of the lighting fixture 200, 300 of the present invention. The reflector lamp shells 210, 310 are integrally formed by a composite material. The composite material is prepared by melting a plastic material and mixing it with an organically modified reflective material to form a molten mixture, and cooling the composite material to form a reflector of a predetermined shape as a reflector lamp shell; wherein the composite material is 90 to 99 weight percent (wt%) of plastic material and 1 to 10 weight percent (wt%) of reflective material. Wherein the formation of the composite material further comprises first forming a molten mixture which is melted and then mixed with the organically modified reflective material to form a molten mixture. Further, the step of forming a reflecting plate of a predetermined shape is preferably formed by injection, extrusion, casting or the like. Preferably, the reflector housing 210 of a predetermined shape is formed by injection molding. M410173 Among them, the plastic material is PE (polyethylene), PMMA (polyalkyl acrylate), ABS (acrylonitrile-butadiene-styrene copolymer), pet (polyester), PC (polycarbonate) , PVC (polyvinyl chloride), PP (polypropylene), pS (polystyrene), LDPE (low density polyethylene), PA (polyamine), p〇M (polyacetal), PET (poly pair) Ethylene phthalate), PBT (polybutylene terephthalate), xpE (Therai〇Plastic Elastomer), PC (polycarbonate), pps (polyphenylene sulfide), LCP (liquid crystal) Polyester), PEEK (polydiether ketone), PAR (polyaryl vinegar) and PI (polyimine). The preparation method of the organic modified reflective material is mainly to stir a solvent mixed with a decane coupling agent until the coupling agent is hydrolyzed into a decane coupling agent solution. Then, a reflective material is added, and the organic modified reflective material is obtained by stirring, centrifuging and drying. . The decane coupling agent is a binder of a reflective material and a plastic material, and may be aminopropyl oxalate, trimethoxy decane, epoxy group-containing decane, or a combination thereof. The reflective material is particularly preferably a material having a refractive index higher than 1.6, which may include titanium dioxide (Ti〇2), zinc oxide (ZnO), an oxidized oxide (Zr〇2), and an acid hindrance (CaC〇). 3), sulphate sulphate 4), oxidized Ming (Al2 〇 3), kaolin and iron oxide (pe2 〇 3). Among them, the reflective material is preferably titanium dioxide. The titanium dioxide used may be classified into anatase type and rutile type titanium dioxide depending on the crystal form, and rutile titanium oxide having a refractive index higher than 2.7 or more may be selected in order to increase the difference in refractive index from the plastic material. The reflector lamp shell is composed of 90 to 99 weight percent (wt%) of plastic material and 1 to 10 weight percent (wt%) of reflective material. In the preparation of the organic modified reflective material described above, the optimum time for the removal of the reflective material via the disturbing is between 30 minutes and 1 hour; and the optimum drying time is between 24 small 7 M410173 and 36 hours. . In a preferred embodiment of the organically modified reflective material, methanol and deionized water are mixed into a methanol aqueous solution at a volume ratio of 1:1, and acetic acid is added to adjust the pH of the aqueous methanol solution to about 4', and then an appropriate amount of Shi Xiyuan is added. The coupling agent (iwt%) is mixed until the coupling agent is hydrolyzed (the solution exhibits a transparent phase). At this time, add an appropriate amount of reflective material Ti〇2 powder for 3 minutes, after centrifugation, pour off the upper layer solution, the lower layer of the residue is washed twice with methanol, centrifuged, and dried at room temperature for 24 hours. Organically modified reflective material Ti〇2. However, in the step prior to forming the reflector lamp housings 210, 310, there are many ways or systems for filtering the molten mixture, such as sand filters or continuous melt filters. In the latter filter, a wire mesh (filter) placed on the piston can be used to push into the melt stream, preferably at least two filters at the same time, so that continuous operation is possible. In normal operation, the wire mesh filter is placed in the melt stream. When the filter is to be replaced, the filter is removed from the melt by the piston associated filter. The filter of the second filter is also replaced in a similar manner. According to this line, the mesh width of the mesh filter is preferably not more than 200 μm, and preferably 50 to ΙΟΟ μιη. The equipment used to form the composite material may be a twin-screw extruder, but is not limited to equipment. Any equipment that can melt the plastic material and mix with the organic modified reflective material to form a molten mixture and cool can be used to form a composite. material. This creation is based on double-carrying (four) as a real complement. The twin-screw extruder of the composite material has various parameters (such as ········································· The job rotation speed is preferably 200 ipm, preferably 3 rpm or more, and the best is 4 〇〇 fpm. 8 M410173 For the use of twin-screw extruders, up to 20 kg/hour of production capacity can be used up to the original formulation. Normal operation should always be carried out within a quarter of the upper limit of the production energy of the extruder used, and preferably within the maximum productivity and rate limits. The upper limit of productivity is determined by the maximum possible torque at the desired low temperature. The shape of the spiral of the twin-screw extruder is also very important. Prior to the addition of the organically modified reflective material for mixing, the plastic material is kneaded via a kneading block to ensure a good molten state. A good melt must also be applied after the melt has formed to form a molten mixture to ensure that no hardening occurs prior to entering the injection tube of the injection machine. Further, if the thickness of the surface of the reflector lamp shells 210, 310 is Ra 〇 〇 5 〜 1.8 私 m', the diffuse reflectance can be made higher, which is more preferable. When visible light is incident on the reflector lamp, visible light rays that are not reflected by the reflector lamp shell are reflected on the surface of the reflector lamp housings 21, 310. Here, it has been found that if the surface roughness of the reflector lamp housing 210 is smaller than the wavelength of visible light (generally, the wavelength field of visible light is called 380 to 780 nm), a large amount is incident on the surface of the reflector lamp housing 210, 310. The visible light is difficult to diffuse and reflect and is easy to be reflected. On the other hand, when the surface roughness of the reflector lamp shells 210, 310 is much larger than the wavelength of the visible light, the incident light incident on the surfaces of the reflector lamp shells 210, 310 will invade the concave and convex gaps on the surface of the reflector lamp shells 210, 310, and is easy. It is absorbed by the reflector lamp housing 210. Therefore, if the Ra of the reflector lamp shells 210 and 310 is less than 0·05 μm, the visible light rays are hard to be diffused and reflected, which is not preferable. On the other hand, if Ra exceeds 1.8 μm, the visible light that is not reflected by the reflector lamp housing 210 and reaches the reflector lamp 210 is easily absorbed by the surface of the reflector lamp 210, which is not suitable. 9 M410173 In the first embodiment, please refer to (4) 2, which is a regenerative lamp 200 made of a cold cathode tube as a light source 220. The body of the present invention has a high reflectivity and a body shaped reflector lamp housing 210 will be a cold cathode tube. The emitted light source is reflected to the desired illumination area. Therefore, the shape of the lamp housing structure is not limited, and any lamp housing capable of accommodating the cold cathode tube can be used as the reflector lamp housing 210 of the present invention. In the second embodiment, please refer to FIG. 3, which is a lighting fixture 300 manufactured by using LED as a light source. The light source emitted by the LED is reflected by using the present invention to form a lamp housing 32 with high reflectivity. The area of illumination required. The color of the light emitted by the LED can be any one of the colors, wherein the outside of the reflector lamp housing 320 can be designed as a diffused light source structure and a concentrated light source structure. In summary, the effect of the creation is: 1. The lighting fixtures disclosed by the invention can solve the problem that the traditional reflector needs to be coated with a reflective layer, thereby reducing the cost and time of the process; 2. The reflector lamp shell of the present invention directly forms a reflector lamp shell through injection molding, This reduces the steps in the process, improves the production efficiency and the cost of the process; 3. The reflector of the present invention reflects light by a curved surface having an open reflection space, and the lamp reduces the ineffective diffused light by the reflector lamp shell. In addition, the temperature of the lamp housing cannot be accumulated, protecting the lamp from temperature damage and prolonging the service life, thereby slowing down the replacement rate of the lamp. 4. The high reflectivity reflector lamp shell of the present invention is capable of illuminating the light source of the reflector lamp housing. Re-reflecting to the area to be illuminated, so that the light source can be used again, thereby achieving the effect of energy saving and carbon reduction; and M410173 5· The composite material consists of a reflective material and a plastic material, so that the composite material has the property of reflecting visible light.
