Description of the Invention: TECHNICAL FIELD The present disclosure relates to an illumination device, and more particularly to a lamp. [Prior Art] In recent years, people's demands for quality of life have become higher and higher, and lighting and lighting have gradually gained attention. As a result, related companies continue to innovate and develop a wide range of luminaires that are not only practical but also aesthetically pleasing. Nowadays, the light-emitting diode is mostly used as the light source of the lamp. However, when the light-emitting diode lamp is turned on, the user can directly see the position of each light-emitting body from the appearance, so that the process is too strong and unattractive. On the other hand, the light-emitting diode is a point light source, and the user's direct vision causes disability glare, and it is also easy to damage vision. Although the manufacturer sands or embosses the glass of the light exit, it is intended to reduce the damage of the light-emitting diode to the eyes of the user, but this will cause a waste of luminous flux. SUMMARY OF THE INVENTION Accordingly, it is a technical aspect of the present disclosure to provide a light fixture for improving the above-described light-emitting diode damage to a user's eyes and wasting light flux. In accordance with an embodiment of the present disclosure, a light fixture includes an elliptical curved reflector, at least one light source, at least one light guide, and at least one end reflector. The elliptical curved reflector has a light exit. The light source is opposite the elliptical curved reflector. The light-shaped light guide plate is disposed on one side of the light exit opening. The end face is reversed. The 201132897 is placed on the other side of the light exit port and is adjacent to the light guide plate. Therefore, the illuminator of the present disclosure can reflect the light and then emit the light by the elliptical curved reflector, and convert the light of the original point source into a surface reflection light source, thereby reducing the damage of the light-emitting diode to the eyes of the user. At the same time, the light guide plate and the end reflector are used to reduce the loss of luminous flux. Embodiments FIG. 1 is a perspective view of a lamp according to an embodiment of the present disclosure. As shown, the lamp 1A of the present embodiment includes an elliptical curved reflector 110, at least one light source 120, at least one light-guide plate 130, and at least one end reflector 140. The elliptical curved reflector 110 has a light exit 111. Light source 120 is opposite the elliptical curved reflector 110. The light-shaped light guide plate 130 is disposed on one side of the light exit port 111. The end reflector 140 is disposed on the other side of the light exit opening 111 and adjacent to the light guide plate 130. Please continue to refer to Fig. 2, which shows a cross-sectional view of the luminaire of Fig. 1 along line 2_2. The light emitted by the light source 12 is first reflected by the elliptical curved reflector 110, and is reflected by the light-guide plate 130 to reflect the illuminance again. On the other hand, the end light reflecting plate 140 reflects the light that is emitted side by side of the light source 120 or the light whose angle of reflection is too large, thereby reducing the loss of luminous flux. There are many choices of the light source 120. However, since the light-emitting diode has the characteristics of power saving and south efficiency, the present embodiment employs a light-emitting diode as the light source 120. The light source 120 is placed at one of the focal points 201132897 of the elliptical curved reflector 110. When the light is reflected by the elliptical curved reflector u, the original point source is converted into a surface light source, which not only changes the direction of the light travel, but also improves the optical uniformity. At the same time, avoid direct radiation damage to the user's eyes. On the other hand, the light that is reflected once is softer than the original light of the light-emitting diode to avoid ghosting and dislocation glare. The number of the light-shaped light guide plates 130 of the present embodiment is two, which are respectively disposed on opposite sides of the light exit opening 111 to allow the primary reflected light to be re-reflected again. Thus, the loss of luminous flux can be reduced. Although only two light-shaped light guide plates 130' are used in the present embodiment, if there is a special illumination requirement, the number of light-shaped light guide plates 130 can be increased or decreased according to the light shape required. In addition, a pivot 150 is disposed at the intersection of the light-shaped light guide plate 130 and the elliptical curved reflector 110, so that the light-shaped light guide plate 130 rotates left and right with the pivot 150 as a fulcrum, and the light-shaped light guide plate is adjusted according to the demand. The angle between the 130 and the elliptical curved reflector 110. On the other hand, for convenience of explanation, FIG. 2 further shows a substrate 121 for arranging the light source 120. In addition to the above, the pivot plate 150 is disposed at the intersection of the light-shaped light guide plate 130 and the elliptical curved reflector 110. A pivot 151 is disposed between the substrate 121 and the light-guide plate 130. Similarly, the light-guide plate 130 is pivoted with the pivot 151 as a fulcrum, and can be rotated left and right according to the requirements to adjust the relationship between the light-guide plate 130 and the substrate 121. angle. The number of the end reflectors 140 of the present embodiment is two, which are respectively disposed on the opposite sides of the light exit opening 111, and are used to reflect the light emitted by the light source 120 sideways and the light of the elliptical curved reflector 110 with a large angle of reflection. To reduce the loss of luminous flux. On the other hand, the end reflector 140 can be connected not only to the elliptical curved reflector 110 but also downwardly to the light guide 201132897, thereby reducing the loss of luminous flux. In order to reduce the energy loss caused by the reflection of the light-emitting diode and increase the uniformity of the light reflection, the present embodiment is plated on one side of the elliptical curved reflector 110, the light-shaped light guide plate 130 and the end-surface reflection plate 140 adjacent to the light-emitting port 111. The upper layer of metal coating. The coating method uses an optical grade coating to increase its reflectivity. On the other hand, in this embodiment, the light-emitting diode is used as the light source 120' under the high-power illumination of the light-emitting diode. The embodiment further includes a φ heat sink 160, such as a heat sink fin, and the heat-emitting diode. Connection to reduce the lighting temperature and increase the life of the LED. According to the embodiment of the above disclosure, the lamp 1 (10) of the present disclosure utilizes a combination of a sugar curved reflector 110, a light guide 13 〇 and an end reflector 140 to reduce the loss of luminous flux, and the metal coating improves the reflectance and reduces The waste of luminous flux can also maintain extremely high efficiency.
