[Prior Art] The lamp of the prior art includes a substrate n for reflecting light, a periphery f 12 extending from the outer edge of the substrate 11 and engaging with the substrate to form an accommodation space 15 A light source module 13 on the inner surface of the peripheral wall 12 and emitting light, and a light transmissive cover 412 disposed under the peripheral wall 12 and used to close the accommodating space 15. ▲ Referring to FIG. 2, the light emitted by the light source module 13 passes through the lower surface of the wire plate 11 and then 'projects downwardly and penetrates the light-transmissive cover μ, and the projected angle is presented (as shown in the figure). The imaginary line is too large and scattered, resulting in low illumination and low illumination uniformity. [New content] Therefore, the purpose of the present invention is to name the φ in the & 1, a luminaire that can improve the uniformity of illumination and illumination. Therefore, the lamp of the present invention capable of improving illuminance and illuminance includes a substrate, a peripheral wall extending downward from the edge of the substrate, at least one ninth source set disposed on the inner surface of the peripheral wall and capable of emitting light, and a reflector disposed on a lower surface of the substrate. The lower surface of the ruthenium reflector forms an optically reflective surface between the plurality of turns and each of which is placed at an acute angle with the substrate, and is used to make the light emitted by the σ海先源杈 group, The reflections of the optically reflective surfaces are reflected downward and substantially perpendicular to the direction of the substrate of M290967. As a result, e_J is only a small month and has a uniformity of illuminance and illuminance. /, [Embodiment] The following and other technical contents, features and effects, in the detailed description of the clear application of the application, will be able to = Figure 3 and Figure 4 'This model can improve illumination and illumination evenly The lamp of the nature is "the embodiment includes - the substrate 2, the wall 3, the two light source modules 4, a reflector 5, and a transparent cover 6. The substrate 2 is made of a metal material such as Ming's heat dissipation. The upper surface (4) of the substrate 2 forms a long groove 21 in which a plurality of wires increase the heat dissipation area. The peripheral wall 3 extends downward from the outer edge of the substrate 2 and cooperates with the substrate 2 to form an accommodation space 3 1 The light source modules 4 are respectively disposed opposite to the inner surface of the peripheral wall 3. In the preferred embodiment, the light source modules 4 are arranged in a plurality of light emitting diode (LED) modules arranged in a row. In practical applications, the light source modules 4 can also be a plurality of light emitting diode modules. The reflector 5 is disposed on the lower surface of the substrate 2 and is made of a metal material such as aluminum. The lower surface of the reflector 5 is formed at a plurality of intervals and each is sandwiched by the substrate 2 An optically reflective surface 51 of the acute angle 53, the angle between the angles of the optically reflective surface #51 and the light source module 4 adjacent to the optically reflective surface 51 varies from small to large The reflecting plate 5 further has a reflecting film 52 disposed on the optical reflecting surface portion 51 M290967 for improving the light reflectance. In the present embodiment, the substrate 2 and the reflecting plate 5 are respectively The manufacturing unit is separately manufactured, and the material is changed into an element which is integrally formed with the reflecting plate 5. The cover 6 is disposed under the peripheral wall 3 for sealing the space 31 and allowing light to pass therethrough. The light emitted by the light source module 4 passes through the optical reflecting surfaces

The above-mentioned 'by the arrangement of the reflector 5' causes the light sources of the light source modules 4 to be reflected by the optically reflective surface, and then projected downward and straightly in the direction of the substrate 2, The smaller and more concentrated projection angle improves the sound of the sound; the 5-day knife @h ... degree and the uniformity of the 々, degree, has indeed achieved the preferred embodiment of the new type of work, when the general application of this new type Equivalent changes and modifications indicate that the two light source modules are only described above, and only one of the novels cannot limit the scope of the new implementation, that is, the simplicity of the view and the new description is still Within the scope of the new patent. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of one of the conventional lamps; FIG. 2 is a projection angle of a light emitted from a side cross-sectional view of a conventional lamp; the figure shows that the present invention can improve illumination and illumination. An exploded perspective view of a preferred embodiment of the luminaire M290967; and FIG. 4 is a side cross-sectional view of the preferred embodiment illustrating the projection angle of the light emitted by the two light source modules.
