New Description: [New Technology Field] This creation is about a kind of light-emitting diode lamp, especially a reflective light-emitting diode lamp. [Prior Art] A fluorescent tube can be said to be a very important invention for indoor lighting. Most of the nighttime indoor lighting in the world is made up of fluorescent tubes. However, the disadvantages of the xenon tube are that it consumes a lot of power and requires high voltage operation. In addition, mercury in fluorescent tubes has been plagued by pollution to the global environment. Therefore, the search for new lighting equipment has aroused great interest from scientists and the business community. - The white light-emitting diode that began to develop in the late tenth century brought a glimmer of illumination.

The resulting yellow glory is then mixed with blue light to produce light (blue light emitting diode with YAG fluorescent powder), turning on the light emitting diode = the prelude to the lighting market. Self-lighting diodes have many advantages over traditional daylight, such as small size (multiple, multiple combinations), low ray "low radiation", low power consumption (low voltage, low current starting #, '1 long (1G 10,000 hours or more), fast response (high frequency 'nine percent protection (shockproof, impact resistant, not easy to break, waste can be recycled, no ^ 彳 planar packaging and easy to develop into thin and light products, etc.) According to some statistics, it has been possible to save the electricity of a nuclear power plant by replacing the fluorescent tube of Taiwan with white light. The 3 M413821 polar body device may save the electricity of a nuclear power plant. The use of solid inorganic inorganic and inorganic light-emitting diodes Fluorescent powder solves the problem of mercury pollution in the dawn lamp. Therefore, the best choice for white light emitting diodes and human future lighting equipment is also the goal of the joint efforts of the world's advanced countries. When a conventional light-emitting diode is used as a light-emitting illumination device, a problem occurs. That is, the light-emitting diode is a point light source, so that uneven light may appear under the irradiation of the distance, resulting in uneven light. In order to clarify the shortcomings of the above-mentioned light-emitting diode lamps, please refer to the first picture and the second picture at the same time: the first picture is a top view of a conventional light-emitting diode lamp; the second picture is a conventional light-emitting A cross-sectional view of a diode lamp includes a lamp 10A, a plurality of LEDs 12A, and a substrate 14A. The slab 14A is disposed in the lamp 1 。. The pole body 12A is worn on the substrate μα. The lamp tube 1QA is a long circular body. The substrate 14A is a printed circuit board, which is matched with a conventional circuit design _ and power supply (not shown). The light-emitting diodes 12A are driven to emit light. It can be seen from the figure that the light-emitting diodes 12A are caused by uneven light and ghosting because they are point light sources. Some of the light-emitting diodes 12A include two or more kinds of light-emitting colors of the light-emitting body.] Because it is a point source, the light-mixing process will require a considerable distance to complete, and a uniform mixed color can be exhibited. [New content] So 'Ben Chuang One of the purpose of the reflective light-emitting diode lamp is to improve the characteristics of the light source of the light-emitting diode to reduce the phenomenon that the light caused by the point light source is not uniform and ghosting. The reflective light-emitting diode lamp of the present invention Another purpose is to improve the light mixing effect of the conventional light-emitting diode lamp. To achieve the above object, the reflective light-emitting diode lamp of the present invention comprises: a lamp tube, at least one substrate and at least one light-emitting diode The lamp tube is a long circular body and includes a reflective housing and a transmissive cover. The reflective housing and the transmissive cover are respectively a long semi-circular body. The reflective housing has an inner side. The light transmissive cover is a light diffusing sheet. The substrates are disposed in the lamp tube. The light emitting diode systems are mounted on the substrates, and the light emitting direction is toward the reflective housing. The light reflecting surface of the reflective housing reflects light and is emitted from the transparent cover. In this way, the light-emitting diodes which are originally point light sources can be used to reflect the characteristics of the point light source and become a line light source, so that the light source will be close to the conventional fluorescent lamp tube, and the uneven light caused by the point light source can be greatly reduced. And the phenomenon of ghosts. In addition, since the characteristics of the point source are eliminated before the light is emitted from the transmissive cover, the light mixing effect is better than that of the conventional light-emitting diode lamp. [Embodiment] Referring to the third drawing, which is a side view of a preferred embodiment of the reflective light-emitting diode lamp of the present invention. Please also refer to the fourth and fifth figures at the same time: the fourth figure is the preferred embodiment of the reflective light-emitting diode lamp of the present invention.彳 view (ie, a cross-sectional view of the figure); Fig. 5 is a top view of a preferred embodiment of a reflective, illuminating one-pole luminaire (i.e., a top view of the first figure). The reflective light-emitting diode lamp according to the preferred embodiment of the present invention comprises: a lamp tube G, two substrates 14 and at least a light-emitting diode 5 M413821 body 12. The tube is a long circular body. The two substrates 14 are respectively disposed on one side of the inner wall of the tube 10 and on the opposite side. The light-emitting diodes 12 are mounted on the two substrates, and the number is not limited, and the brightness of the candle light required for the matching is increased or decreased. The δ illuminator 10 includes a reflective housing 16 and a transmissive cover 18. The reflective housing 16 of the tube 10 has a reflective surface on the inside for reflecting light. - The light-transmissive cover 18 of the Xuan Denguan 1 is a light-diffusing sheet, which can diffuse the light to reduce the phenomenon of the point source. The light-transmissive housing of the light tube and the light-transmissive cover 18 of the light-receiving lamp are respectively a long semi-circular body to constitute the light tube 10'. However, the reflective housing 16 and the transparent cover 18 may also be The integrally formed transparent casing is formed by providing a reflective surface corresponding to the elongated semicircular inner surface of the reflective casing 16. The two substrates 14 are printed circuit boards that are driven to illuminate the light-emitting diodes 12 in accordance with conventional circuit designs and power supplies (not shown). The light-emitting diodes 12 are directed toward the reflective housing 16 of the bulb 10, and the reflective surface of the reflective housing 16 of the bulb 10 reflects light from the tube 1 The translucent cover 18 is ejected. 'This will make the light-emitting diodes 12, which are originally point sources, use the reflection to make the point source characteristics disappear, and become a line source or a surface source. Therefore, the source will be close to the conventional fluorescent tube, and the point is greatly reduced. The phenomenon of uneven light and ghosting caused by the light source. In addition, since the light is removed from the light-transmissive cover 18 of the tube 1 before the light-emitting cover 18 is emitted, the light is mixed (that is, the light-emitting diodes 12 include two or more light-emitting diodes). The effect will be better than the conventional light-emitting diode lamps. In addition, the number of the substrate 14 is not limited to two, for example, may be 6 M413821, and is disposed on one side of the inner wall of the lamp ίο, or even at the bottom of the translucent cover 18 of the lamp tube 10, as long as The light-emitting diodes 12 are directed toward the reflective housing 16 of the bulb 10 to reflect light from the reflective surface of the reflective housing 16 of the tube 1 and then from the tube 1 The translucent cover 18 can be emitted. In summary, when Zhiben's creation has industrial applicability, novelty and progress, the structure of this creation has not been seen in similar products and public use, fully in line with the requirements for creating patent applications, and applied for patent law.
