Abstract: A vehicle lamp having a discharge bulb which prevents radiation of electromagnetic waves toward the forward positions of the lamp. Radiation into the other directions is prevented by shielding members disposed around the lamp. A shade disposed in front of a discharge bulb attached to a reflector is made of metal and a stem of the shade is secured to the reflector in a state where the stem is electrically connected to a socket fixture. The shade is placed at ground potential through the fixture. Thus, the front portion of the discharge bulb is shielded and prevents radiation of the electromagnetic waves to positions in front of the lamp.

Abstract: A protective assembly for a standard fluorescent lamp includes a protective tube that is preformed from a semi-rigid, non-frangible polymeric transparent or translucent material that is stabilized against ultraviolet radiation and is received over the glass tube with its inner surface substantially uniformly spaced apart from the outer surface of the glass tube to form an air space for insulation of the lamp. The desired uniform spacing between the lamp tube and the protective tube is established by a spacer ring located adjacent each end of the glass tube and adhesively bonded to the glass tube. Each spacer ring is formed of band of a semi-rigid polymeric foam strip material that is resistant to heat and ultraviolet radiation. The foam spacer ring forms a snug fit with an inner surface of the protective tube but allows the protective tube to be slid lengthwise onto the lamp.

Abstract: A probe light is provided with two power lines passed through a long tubular small diameter brass rod extended from a handle with a plug in socket connection to a power supply to a small cross sectional halogen lamp bulb socket for a small diameter halogen light bulb. The halogen light bulb used is a high intensity light bulb pulling relatively high amperage developing considerable heat. The tubular small diameter brass rod, that is bendable for use convenience, conducts heat away from the lamp bulb socket and the plug in leads of the lamp bulb are bent in a wave shape to insure good electrical contact through an extensive heat temperature range. The lamp bulb leads plug into internal openings in the two socket pins held within the lamp bulb socket with the socket pins being heavy duty pins also conducting heat away from the lamp bulb leads.

Abstract: The high pressure discharge lamp has containment structure in the outer envelope which encloses the discharge vessel. The containment structure consists of a glass cylindrical sleeve closed at its ends by a metal plate. The plates, the cylindrical sleeve and the discharge vessel are combined as a subassembly. The metal plates are provided with tongues bearing on the glass cylindrical sleeve and the outer envelope. The lamp has a flexible conductor which extends from the current lead-through conductor remote from the stem to the lamp stem and bears on the outer envelope. The containment structure prevents failure of the outer lamp envelope in the event of explosive failure of the discharge vessel.

Abstract: A high pressure metal halide discharge lamp having a containment sleeve closed by a pair of metallic end caps for containing arc tube fragments in the event of explosive failure of the arc tube. Insulators secured in the end caps electrically insulate the arc tube lead-throughs from the end caps. Metallic tubes fixed on the lead-throughs butt against the insulators to secure the arc tube between the end caps and hold the end caps against the containment sleeve. Photoelectric emission from the end caps is avoided by electrically isolating the end caps or by providing a dielectric coating on end cap surfaces exposed to ultraviolet radiation.

Abstract: A brooder lamp for small animals, especially pigs, has a stainless steel reflector housing a bulb socket and a resilient metal plate extending across the reflector, in front of the socket. An opening in the plate is sized to pass the narrow neck of the bulb but to engage the widening port and to bias it away from the socket. This provides a secure mounting for the bulb in the socket to inhibit damage due to impact with the lamp of playful animals.

Abstract: A miniature florescent tube assembly holder and adapter for use in conjunction with the original manufacture or retrofit replacement of the conventional incandescent bulb and socket assembly of a lamp.

Abstract: When it is desired to increase the light yield from fluorescent tube installations without reflectors by providing the fluorescent tubes with a reflector, it is often difficult to mount and position the reflector in an existing light fitting, and it is even more difficult when such fluorescent tubes sit freely on a wall or a ceiling, or are mounted externally on a fitting.For this purpose the reflector system comprises a reflector (4) of anodized aluminium and securing elements (1) consisting of spring straps which surround the fluorescent tube (5) and secure the reflector (4) to the fluorescent tube by means of friction between the securing element's strap (1) and the fluorescent tube (5).Also provided is a second embodiment of the securing element which is intended for fittings with a flat surface. In this case the securing element has some protruding ends which bear against the flat surface of the fitting and thus position and secure the reflector in the correct position.
