Definitions

  • the present disclosure relates to a lamp.
  • lamps in a building are mostly installed on the ceiling to directly illuminate the interior space, so as to obtain maximum illumination.
  • the light of direct illumination is very harsh, which not only causes glare but also may make users feel fatigue and apathy, so recent trends are beginning to promote the use of indirect illumination.
  • Indirect illumination uses techniques in which lamps are installed below the ceiling, and the lamps illuminate toward the ceiling, so that the light emitted by the lamps will be illuminated on the ceiling, and then be reflected to the interior space by the ceiling, and thus softens the light. Therefore, indirect illumination not only can effectively improve the aforementioned disadvantages, but also can significantly improve the atmosphere in the interior space.
  • Indirect illumination must be reflected by the ceiling, therefore the illumination of the lamps are often significantly reduced, so the current practice is to install a main lamp on the ceiling used as direct illumination and install a plurality of auxiliary lamps used as indirect illumination. Therefore, the users can selectively use the direct illumination or the indirect illumination at any time in accordance with the needs.
  • the main lamp and the auxiliary lamps are independent units, so they not only occupy more interior space but also require a higher cost.
  • the auxiliary lamps must be installed adjacent to the ceiling to reduce the attenuation of illumination, so the lamps need to use several holders or additional shelves to fix the auxiliary lamps, which may result in even higher installation costs.
  • the disclosure provides a lamp.
  • the lamp includes a base and a light-emitting module.
  • the base has a hollow portion.
  • the hollow portion has a first opening and a second opening.
  • the first opening and the second opening are respectively located at two opposite sides of the base.
  • the base further includes a mounting surface and a first reflective surface located within the hollow portion.
  • the mounting surface faces toward the first opening.
  • the first reflective surface substantially faces toward the mounting surface and the second opening.
  • the light-emitting module is disposed at the mounting surface and emits a light toward the first opening. A part of the light is reflected by the first reflective surface and then leaves from the second opening.
  • the light-emitting module includes a circuit board and a plurality of light sources.
  • the circuit board is fixed to the mounting surface.
  • the light sources are disposed on the circuit board along an arrangement direction.
  • the circuit board further includes an electrical connector.
  • the electrical connector is located at an end of the circuit board.
  • the lamp further includes a connecting member and a plurality of fasteners.
  • the connecting member is configured to connect the base and another base of another lamp.
  • the fasteners are fastened to the connecting member respectively through the base and the another base, so that the base and the another base are fixed to the connecting member.
  • the connecting member has a passage.
  • the electrical connector and another electrical connector of the another lamp insert into the passage and are electrically connected to each other.
  • the light sources are blue light-emitting diodes.
  • the light-emitting module further includes a fluorescent powder mask.
  • the fluorescent powder mask is fixed to the circuit board and covers the light sources.
  • the lamp further includes a lampshade.
  • the lampshade is fixed to the base and covers the first opening.
  • the lampshade is transparent, and the material of the lampshade includes PMMA (Poly(methyl methacrylate)).
  • the hollow portion further has a third opening.
  • the third opening and the second opening are located at the same side of the base.
  • the base further includes a second reflective surface located within the hollow portion.
  • the mounting surface is located between the first reflective surface and the second reflective surface.
  • the second reflective surface substantially faces toward the mounting surface and the third opening. Another part of the light is reflected by the second reflective surface and then leaves from the third opening.
  • the lamp further includes a first diffusion sheet and a second diffusion sheet.
  • the first diffusion sheet is located at the second opening.
  • the second diffusion sheet is located at the third opening.
  • the base is an extruded aluminum substrate, and the first reflective surface and the second reflective surface are anodized surfaces.
  • the lamp of the disclosure disposes the light-emitting module in the hollow portion of the base, and the light-emitting module faces toward the first opening of the hollow portion, so that the light emitted out of the first opening by the light-emitting module can serve as direct illumination of the lamp.
  • the base of the lamp has the reflective surface in the hollow portion, and the reflective surface can reflect a part of the light emitted by the light-emitting module to the second opening of the hollow portion, so that the light emitted out of the second opening can serve as indirect illumination of the lamp. That is, the lamp of the disclosure is equipped with secondary optical design.
  • an extruded aluminum substrate is used as the base of the lamp, and the reflective surface is anodized to obtain excellent reflectance, so the lamp of the disclosure is lighter and thinner than conventional lamps in the market, and conventional reflective cups that are additionally installed can be replaced by the reflective surface of the lamp of the disclosure. Therefore, the lamp of the disclosure can achieve the purposes of reducing footprint, optical space, and acquisition costs.
  • the base made of the extruded aluminum substrate has a cooling effect, so the heat generated by the light-emitting module can be transmitted to the base via the circuit board of the light-emitting module, and then be directly dissipated from the surface of the base.
  • the circuit board has an autologous heat dissipation function, so the circuit board combined with the base made of the extruded aluminum substrate can dissipate the heat generated by an 18-25 W lamp.
  • Fig. 1A is a perspective view of a lamp 1 according to an embodiment of the disclosure.
  • Fig. 1B is an exploded view of the lamp 1 in Fig. 1A .
  • Fig. 2 is a cross-sectional view of the lamp 1 in Fig. 1A along line 3-3'.
  • the lamp 1 includes a base 10 and a light-emitting module 12.
  • the base 10 of the lamp 1 has a hollow portion 100.
  • the hollow portion 100 of the base 10 has a first opening 100a, a second opening 100b, and a third opening 100c.
  • the first opening 100a and the second opening 100b of the hollow portion 100 are respectively located at two opposite sides of the base 10 (i.e., the lower side and the upper side in Fig. 2 ), and third opening 100c and the second opening 100b are located at the same side of the base 10.
  • the base 10 further includes a mounting surface 102, a first reflective surface 104, and a second reflective surface 106 located within the hollow portion 100.
  • the mounting surface 102 of the base 10 faces toward the first opening 100a and located between the first reflective surface 104 and the second reflective surface 106.
  • the first reflective surface 104 of the base 10 substantially faces toward the mounting surface 102 and the second opening 100b.
  • the second reflective surface 106 of the base 10 substantially faces toward the mounting surface 102 and the third opening 100c.
  • the light-emitting module 12 of the lamp 1 is disposed at the mounting surface 102 of the base 10 and emits a light toward the first opening 100a of the hollow portion 100. Therefore, the light emitted out of the first opening 100a by the light-emitting module 12 can serve as direct illumination of the lamp 1.
  • the beam angle of the light-emitting module 12 covers at least a part of the first reflective surface 104 and at least a part of the second reflective surface 106, a part of the light emitted by the light-emitting module 12 is reflected by the first reflective surface 104 of the base 10 and then leaves from the second opening 100b of the hollow portion 100, and another part of the light emitted by the light-emitting module 12 is reflected by the second reflective surface 106 of the base 10 and then leaves from the third opening 100c of the hollow portion 100.
  • the light emitted out of the second opening 100b and the third opening 100c of the hollow portion 100 can serve as indirect illumination for the lamp 1.
  • the lamp 1 of the disclosure is equipped with secondary optical design within the hollow portion 100 of the base 10, so as to create lighting effects on the top side and the bottom side of the lamp 1.
  • the light emitted out of the second opening 100b and the third opening 100c are initially reflected by the first reflective surface 104 and the second reflective surface 106 respectively and then consequently reflected by the ceiling (not shown), so as to provide a light softening effect better than those provided by conventional lamps, and to make the atmosphere in the interior space more better.
  • the base 10 of the lamp 1 is an extruded aluminum substrate, and the first reflective surface 104 and the second reflective surface 106 are directly formed by extruding aluminum, so the lamp 1 of the disclosure is lighter and thinner than the conventional lamps in the market, and conventional reflective cups that are additionally installed can be omitted. Furthermore, in the embodiment of the disclosure, the first reflective surface 104 and the second reflective surface 106 of the base 10 are anodized surfaces, so as to obtain excellent reflectance. Hence, the lamp 1 of the disclosure can achieve the purposes of reducing footprint, optical space, and acquisition costs.
  • the first reflective surface 104 and the second reflective surface 106 of the base 10 are plated surfaces, so as to similarly obtain the excellent reflectance.
  • the first reflective surface 104 and the second reflective surface 106 of the base 10 are cambered surface and substantially recessed away from the light-emitting module 12, but the disclosure is not limited in this regard. In practical applications, the first reflective surface 104 and the second reflective surface 106 of the base 10 can also be flat surfaces.
  • the light-emitting module 12 of the lamp 1 includes a circuit board 120, a plurality of light sources 122, and a fluorescent powder mask 124.

  • An outer edge of the circuit board 120 is flush with that of the fluorescent powder mask 124 without protruding out of that of the fluorescent powder mask 124, so as to prevent the light leakage problem caused by that a part of the circuit board 120 is not covered by the fluorescent powder mask 124.
  • the light-emitting module 12 is a light bar type light-emitter.
  • the light sources 122 of the light-emitting module 12 are blue light-emitting diodes. After the blue light emitted by the light sources 122 passes through the fluorescent powder mask 124, the blue light is transformed into a white light by the fluorescent powder mask 124.
