  • Patent number: 7476013
    Abstract: A light bar is described that is of a modular construction based on one or more large circuit boards that are populated with light beam assemblies and then fastened to an interior space of the light bar housing. Keys that automatically align the light beam assemblies on each of the boards precisely control placement of the assemblies on the board. In turn, each of the boards is keyed to the interior of the light bar housing so that when the board is fastened to the housing the light beam assemblies are automatically registered into alignment with the lenses in the housing so that the beams from the assemblies are properly oriented. The light bar is inexpensive to fabricate and can be assembled quickly and reliably, yet it provides for a high degree of customization, which is a requirement in the emergency vehicle lighting industry.

  • Patent number: 7473014
    Abstract: An LED lamp has a convex lens 3 which has an upper portion 5 and a lower portion 6. An upper curved surface 5A of the upper portion is different in shape from a lower curved surface 6A of the lower portion 6 so as to refract rays of light from an LED chip 2 more strongly than the lower curved surface 6A does. This avoids reflection of incident outside light toward a front and hence prevents misrecognition. An interface plane S1 between the upper and lower portions 5 and 6 of the convex lens 3 is located on an upper end face 2A to thereby prevent collection of outgoing light upon the interface plane S1 and generation of an irregular emission peak at the front.

  • Patent number: 7461958
    Abstract: A lamp holding apparatus for mounting a lamp to a lamp mounting member includes a mounting plate provided with a locking portion which protrudes to a base side, inserted into a mounting hole provided at the base and is lockable to a peripheral edge of a back side thereof. The mounting plate is provided with a pin which protrudes to an opposite side from the base side and is capable of being gripped by an operator at a time of being attached to and detached from the base. The locking portion is disposed at a position corresponding to a back side of the pin. As a result, when the locking portion is inserted into the mounting hole while gripping the pin, both the locking portion and the mounting hole are easily positioned.
