Description

Lamp

This creation is about a luminaire.

Traditional lighting consumes a lot of energy, and developing lighting energy will be the most important new energy technology. Today, semiconductor lighting uses a high-power, high-brightness Light Emitting Diode (LED) as a light source. Light-emitting diodes have the potential to widely replace traditional lighting sources because of their high luminous efficiency, energy saving, longevity, environmental protection (without mercury), fast start-up, and directivity.

When high-power high-brightness light-emitting diodes are used as the light source for illumination, it is necessary to cooperate with a high-efficiency heat-dissipating mechanism to minimize the junction temperature of the light-emitting diodes in order to exert the above-mentioned advantages. Otherwise, the illuminating brightness and service life of the illuminating diode lamp will be greatly reduced, except that the energy-saving effect of the illuminating diode lamp will be inconsistent, and the reliability of the illuminating diode lamp will be directly impacted, or a serious light decay may be caused. The illuminating diode lamp is disabled.

However, the current structure of the recessed light products on the market has been unable to meet the requirements of the current lighting market for the size, luminous efficiency and heat dissipation efficiency of the recessed lamps. A recessed light product with a power of about 7-12 watts (Watt) In fact, there is currently no recessed light product on the market that can satisfy both large light-emitting area and thin design. Moreover, even if the heat sink is deliberately thinned, the heat-dissipating ability cannot be improved (limited by the volume requirement and the heat-dissipating area cannot be further increased), and the overall illumination of the lamp cannot meet the standard requirement. If the fan module is additionally added to increase the overall heat-dissipating capability of the luminaire, in addition to the increase in the overall manufacturing and energy consumption costs of the luminaire, increasing the number of types of parts can also cause complicated assembly, which leads to assembly time-consuming and Increase labor costs.

Therefore, it is proposed that a recessed light product that can satisfy the large light-emitting area and the thinned design is one of the problems that the industry is eager to invest in research and development resources.

The present application provides a luminaire that includes a heat sink, a light emitter, and a lens structure. The heat sink includes a cup body and a plurality of heat sink fins.

The light emitter is facing the light surface. The reflective layer is disposed on the wall surface and extends to the light incident surface to form a light passing region on the light incident surface. The light emitter is optically coupled to the body via a light pass region.

In an embodiment of the present invention, the light incident surface and the light exit surface are conical surfaces. The entrance surface is concave toward the light exit surface. The light exiting surface is concave toward the light entrance surface.

In an embodiment of the present invention, the light emitter described above includes a light source and a first lock. The light source is disposed at the bottom of the accommodating groove and is thermally connected to the cup body. The first locking device locks the light source to the bottom of the receiving slot.

In an embodiment of the present invention, the cup body further has a bearing portion. The bearing portion is located in the receiving groove and adjacent to the opening. The lens structure also includes an extension. The extension portion is formed by extending outward from the edge of the light-emitting surface, is limited to be located in the opening, and is carried on the bearing portion.

In an embodiment of the present invention, an annular groove is formed between the extension and the opening. The luminaire also contains an annular gasket. An annular gasket seals the annular groove.

In an embodiment of the present invention, the cup body further has an annular end surface. The annular end surface abuts the periphery of the opening and faces away from the outer surface. The cup also has a plurality of perforations. Each perforation communicates with the annular end face and the outer surface.

Specifically, the area of the light-emitting surface 140c of the main body 140 is larger than the area of the light-incident surface 140a. Therefore, the wall surface 140b is gradually expanded by the light-incident surface 140a toward the light-emitting surface 140c. The light emitter 12 of the luminaire 1 faces the light incident surface 140a of the body 140. The reflective layer 142 of the lens structure 14 is disposed on the wall surface 140b of the body 140 and extends to the light incident surface 140a to form a light-passing region 140a1 on the light-incident surface 140a. The light emitter 12 of the luminaire 1 is optically coupled to the body 140 of the lens structure 14 via the light-passing region 140a1 on the light-incident surface 140a (ie, the light emitted by the light emitter 12 passes through the light-passing region 140a1 and enters the body 140). . Thereby, the lens structure 14 of the present embodiment itself has the ability to reflect, so that not only the optical efficiency of the lamp 1 but also the distance between the light emitter 12 and the lens structure 14 can be effectively shortened, so that the lamp 1 can be made thinner.

Further, the light incident surface 140a and the light exit surface 140c of the body 140 are both conical surfaces. The light incident surface 140a of the body 140 is recessed toward the light exit surface 140c, and the light exit surface 140c is recessed toward the light incident surface 140a (as shown in FIG. 4). In an embodiment, the concave apex of the light incident surface 140a and the concave apex of the light exit surface 140c may be opposite to each other.

The light source 120 of the light emitter 12 is disposed at the bottom of the receiving groove 100b of the cup 100, and is thermally connected to the cup 100 (that is, the light source 120 and the cup 100 are connected in a manner capable of conducting heat energy). In other words, the heat generated by the light source 120 of the light emitter 12 during operation can be directly conducted to the heat sink 10 directly by heat conduction, and the heat sink 10 performs heat removal. In this embodiment, the light incident surface 140a of the body 140 is recessed toward the light exit surface 140c. The light source 120 of the light emitter 12 is raised upward relative to the equivalent focus of the lens structure 14, so that the height of the lens structure 14 can be further shortened and the luminaire 1 can be made thinner.

The annular gasket 16 of the luminaire 1 can be tightly clamped between the extension 144 of the lens structure 14 and the opening 100a of the cup 100 such that the lens structure 14 does not slide relative to the heat sink 10, thereby improving the lens structure 14 and Assembly stability between the heat sinks 10. Moreover, the annular gasket 16 sandwiched between the extending portion 144 of the lens structure 14 and the opening 100a of the cup 100 has the effect of sealing the annular groove G and has a waterproof function (that is, the liquid outside the lamp 1 can be prevented from passing through The annular groove G enters the receiving groove 100b) of the cup 100.

In the present embodiment, the mating annular gasket 16, the extension portion 144 of the lens structure 14, and the opening 100a of the cup 100 can achieve the IP44 waterproof rating, but the present invention is not limited thereto.

As shown in FIGS. 2A and 2B, in the present embodiment, the cup 100 of the heat sink 10 further has an annular end surface 100e.
