The surface mounted LED package disclosed herein includes an LED having a first surface, a second surface opposite to the first surface, two electrical contacts on the first surface, and a light emitting portion in the second surface; a housing mounted on the LED and having a generally rectangular parallelepipedal shape, a first passageway extending from a first surface of the housing part way through the housing, the first passageway being sized, shaped, and positioned to receive the second surface of the LED such that the light emitting portion of the second surface faces into the first passageway, and a second passageway extending from a second surface of the housing to a third surface of the housing and communicating with the first passageway; and a lens received in the second passageway and having a first radiating surface located outside the housing and an internal reflecting surface located inside the housing above the light emitting portion of the LED in position to reflect light from the light emitting portion of the LED toward the radiating surface.
The combination of a light pipe and a face plate having an opening to receive the light pipe. The light pipe and the face plate opening are formed with complementary polarizing features so that the light pipe can only be inserted into the opening with a predetermined angular orientation about its axis. After insertion into the opening, the light pipe is rotated about its axis to lock it in place. The face plate may then be secured to the edge of a circuit board with the light pipe in alignment to receive light emitted from an indicator light source mounted to the circuit board.
A light emitting diode mounting structure for a light emitting diode having four leads has two metal plates fixed to wire on a housing. The leads engage the metal plates in electrical contact therewith and are supported by the metal plates, a surface part of which reflects light from the light emitting diode.
A lightpipe or lightpipe array is utilized for redirecting light from a surface mounted LED. The lightpipe includes a first surface portion which is aligned with a surface mounted LED on a circuit board when the lightpipe is mounted on the circuit board, a first passageway comprising a plurality of first reflecting surfaces for redirecting light received at the first surface portion in a first direction, a second passageway extending from the first passageway comprising a plurality of second reflecting surfaces for redirecting the light received from the first passageway in a second direction which is different from the first direction, and a light radiating surface portion through which the light received from the second passageway exits so as to provide a visual indicator. Utilization of a plurality of lightpipes in a lightpipe array permits the array in the form of a single molded part to collect light from multiple LEDs and to redirect light to different locations without a perceptible mixture of light between adjacent LEDs.
A surface-mounted lighting system and method wherein a lamp (e.g., an LED) is mounted within a surface (e.g., a wall, the wall of a pool or spa, a panel, etc.) such that it casts light to one side of the surface. A lighting system of the present invention comprises a) a lens cap/light emitting diode/first connector subassembly and b) a second connector/wire subassembly. A first connector located on the lens cap/light emitting diode/first connector subassembly is connectable to the second connector located on the second connector/wire subassembly such that power may be delivered through the second connector/wire subassembly to the lamp. Thereafter, when it is desired to remove or change the lamp, the first connector is disconnected from the second connector and the entire Lens cap/LED/first connector subassembly may be removed and replaced. In this manner, the lamp may be changed from a front or exposed side surface of a wall in which the lamp is mounted without the need to access wiring that is concealed or enclosed behind or on the opposite side of that wall.
A lamp assembly (10) for use as a vehicle marker lamp or a vehicle clearance lamp is disclosed. A lamp assembly includes a multifaceted prismatic diffuser (12) to which a number of LEDs (14) are fitted. The diffuser has an outwardly directed portion (20), a center portion (22), and an inwardly directed portion (24). The outwardly directed portion and inwardly directed portion are both formed with angularly offset facets (26-38). The LEDs are fitted into openings (40) that are formed in the facets (32, 34) of the inwardly directed portion of the diffuser. When the LEDs are energized, the light emitted thereby is initially diffused throughout all of the diffuser. It is then emitted from the facets forming the outer portion of the diffuser such that it can be seen over a wide viewing angle.
