A modular display case having a series of adjacent panels an upper portion of two panels supporting an item for display and base portion for support. The base portion may also include a chamber for housing an illuminating LED strip within the base of the case. The case is made from multiple layers of material the front panel and back panel which are connected with fasteners to allow the display to be taken apart to situated the item therein. The item held in the display is visible through the clear panel material which provides viewing windows on the front and rear of the case.

One embodiment provides a mapping device including a memory configured to store instructions. A processor is configured to execute the instructions to: receive geolocation information for the mapping device from a global positioning system (GPS) device; receive unique identification information; transmit the geolocation information and the unique identification information through a network; and cause an update to prior geolocation information that corresponds to an address in a mapping database.

A local light-emitting road sign board apparatus is disclosed. Local light-emitting panels, displaying road guides in the form of a character, numeral, symbol, or figure, are independently inserted and installed in openings for road sign units that are provided in a main substrate. A sub substrate and a retroreflective sheet are laminated and bonded on each local light-emitting panel so as to form a road sign unit. A retroreflective sheet is also bonded on the main substrate so as to form the background of a road sign unit. When one of road sign units fails, it is possible to simply separate, repair or replace, and reinstall only the failed road sign unit while leaving the others intact.

The invention relates to an emergency luminaire (1) with a housing (2) accommodating a light source (3) and control means (4) configured to control light emission of the light source (3). The housing (2) is configured for attaching an emergency sign unit (5) to the housing (2) such that the light emitted by the light source (3) lights the emergency sign unit (5) when the emergency sign unit is (5) attached. The control means (4) is configured to determine whether the emergency sign unit (5) is attached to the housing (2) or not; and control the light emission of the light source (3) according to a first operation mode when no emergency sign unit (5) is attached to the housing (2), and according to a second operation mode when the emergency sign unit (5) is attached to the housing. The second operation mode is different from the first operation mode.

The present disclosure provides an electronic shelf label with an integrated light guiding structure, including: a screen (6), a light guiding sleeve (7) and an indicator light (4). The light guiding sleeve (7) is disposed to sleeve the screen (6) along an edge thereof. A rear end face of the light guiding sleeve (7) is attached to the indicator light (4). A light guiding post (701) is formed at a position, which is on a front end face of the light guiding sleeve (7) and overlapped with the indicator light (4). The present disclosure solves the technical problems of complicated internal structure and high cost of the electronic shelf label.
