Description of the Invention: [Technical Field of the Invention] The present invention relates to a lamp. [Prior Art] Advances in semiconductor technology 'Light-emitting diodes (LEDs) can achieve more and more power, and the intensity of the emitted light is getting higher and higher. In addition, the light-emitting diode has the advantages of power saving, long service life, environmental protection, fast startup, small size, and the like. Therefore, light-emitting diodes are also widely used in lighting equipment, traffic signs, displays, optical mice, etc., and there is a tendency to gradually replace traditional fluorescent lamps. The light-emitting body has directivity, that is, the light emitted by it is concentrated in one direction. When the light-emitting diode is used for general illumination %, it is usually necessary to arrange the light-emitting diodes so that the light can be directed in different directions, so that the light in the environment can be illuminated as much as possible. In a conventional light-emitting diode lamp, the light-emitting diodes are arranged to be rotationally symmetric with respect to a symmetry axis, and the light emitted by the light-emitting diodes is radiated in a radial direction perpendicular to the axis of symmetry. However, since the light is concentrated in the radial direction, such a light-emitting two-strip lamp has a problem that the illuminance is insufficient in the axial direction (the direction along the axis of symmetry). For example, when such a light-emitting diode lamp is mounted on a ceiling, the illumination below the light-emitting diode lamp is insufficient, which is disadvantageous for the user to read or engage in other activities that require lighting. 201128132 EL98017 3I361fw£doc/n The light emitted by his illuminating light-emitting diode will be emitted along the axial direction. ^: Hair = body must be used at the same time: set direction π 曰 'each Χ... The internal structure is too complicated, which is not conducive to political heat, and raises the cost of making the light-emitting diodes. SUMMARY OF THE INVENTION An adequate lamp provides a luminaire that can provide multiple directions at the same time. Embodiments provide a luminaire that includes a reflector llght module. The reflector has a bottom and a light exit section. A part of each of the light-emitting modules is disposed on the reflector lamp and each of the light-emitting modules includes a carrier plate and a plurality of light-emitting elements. These illuminations are configured on the carrier board. The portions of these illuminating elements are located between the lamp and between the bottom and the exit section, and the other portions of the illuminating elements are exposed outside the reflector. In one embodiment of the invention, each of the light emitting elements has an optical axis, and the optical axes of the light emitting elements are substantially parallel to the light exiting cross section. In an embodiment of the invention, each of the light-emitting elements is, for example, a light-emitting diode. In one embodiment of the x ft invention, the illuminating elements of each of the illuminating modules are arranged in a direction substantially perpendicular to the cross section of the light exiting. In one embodiment of the invention, the lighting modules are disposed around a central axis that passes through the 201128132 EL98017 31361 twf.doc/n light section. In one embodiment of the invention, the luminaire further includes a heat sink, a portion of the heat sink is disposed in the reflector, and the light modules are disposed on the heat sink. The heat sink can have a plurality of recesses' and the light emitting modules are respectively disposed in the recesses. These grooves may extend in a direction substantially perpendicular to the exit cross section. In an embodiment of the invention, the luminaire further includes a driving circuit, wherein φ is disposed at the bottom of the reflector and is located in the reflector, and the driving circuit is electrically connected to the illuminating modules. The luminaire can further include an electrical connector disposed on the bottom and outside the reflector, wherein the electrical connector is electrically connected to the driving circuit. In one embodiment of the invention, the luminaire further includes a light transmissive cover disposed on the reflector cover, wherein another portion of the illuminating elements exposed outside the reflector cover is received in the translucent cover. The light transmissive cover can have a plurality of venting openings and the venting openings extend through the translucent cover. In one embodiment of the invention, the reflector has a reflective surface that is located on the inner wall of the reflector. The light emitted by the light-emitting elements located in the reflector is reflected by the reflecting surface to the light-emitting section, and the light emitted by the portions of the light-emitting elements located in the reflector is transmitted through the light-emitting section in the direction away from the bottom. The reflecting surface is, for example, a concave surface. The reflector can have a plurality of venting openings and the venting openings extend through the reflector. Another embodiment of the present invention provides a light fixture comprising the above reflector lamp cover, the light emitting module and a light transmissive lamp cover. Each of the light-emitting modules is disposed around a central axis passing through the light-emitting section. The translucent lampshade is disposed on the reflector cover 201128132 EL980I7 3I36Itwf.doc/n, wherein the other portion of the light-emitting element exposed to the outside of the reflector cover is housed in the translucent lamp cover. Based on the above, in the lamp of the embodiment of the invention, a part of the light-emitting elements of the respective light-emitting modules are located inside the reflector, and the other portion is exposed outside the reflector. Since the light emitted by the light-emitting elements located in the reflector is reflected by the reflector, and is directed away from the bottom of the reflector, and the light emitted by the light-emitting elements exposed outside the reflector is directed to the other direction, The luminaire of an embodiment of the invention can provide sufficient illumination in multiple directions simultaneously.

The venting opening 118 and the venting opening 164 are, for example, elongated slits. However, in other embodiments, the venting opening U8 and the venting opening 164 may also be openings in other shapes. In summary, in the luminaire of the embodiment of the invention, a part of the illuminating elements of each illuminating module is located inside the reflector, and the other part is escaping outside the reflector. Since the light emitted by the illuminating element in the reflector is reflected by the reflector, it is directed away from the bottom of the reflector, in the direction of 201128132 EL98017 31361 twf.doc/n (such as the axial direction), and is exposed to the outside of the reflector. The light f of the element is directed to the other direction (such as the radial direction), so that the lamp of the present invention can provide sufficient illumination in multiple directions at the same time, for example, the intensity of the emitted light and the light emitted in the radial direction. The intensity is relatively close. The present invention has been disclosed in the above embodiments, but it is not intended to limit the invention. Any of the technical fields of the present invention may have a general knowledge, and may be modified and moistened without departing from the spirit and scope of the present invention.
