Furthermore, while pulse start lamps exist, these lamps are typically not interchangeable with probe start lamps (such as probe start QMH lamps) due to metal parts and insufficient clearance in the outer sheath where breakdown may occur

Embodiment Construction

[0041] What follows is a description of illustrative embodiments that exhibit the above-noted features and advantages, as well as additional features and advantages, when considered in conjunction with the following drawings. In the following description, illustrative details such as architectures, interfaces, technologies, element attributes, etc. are set forth for purposes of explanation rather than limitation. However, it will be apparent to one of ordinary skill in the art that other embodiments that depart from these details should still be understood to be within the scope of the appended claims. Also, for the purpose of clarity, detailed descriptions of well-known devices, circuits, tools, techniques and methods are omitted so as not to obscure the description of the present system. It should be expressly understood that the drawings are included for purposes of illustration and do not represent the scope of the present system. In the drawings, the same reference numbe...

Abstract

A high power ceramic discharge metal halide (CDM) lamp having a shroud-type enclosure assembly is disclosed. The lamp includes: a first shield (138) having a first wall forming a cylinder and defining a first cavity; a second shield (136) positioned within the first cavity and comprising A second wall forming a cylinder and defining a second cavity located within the first cavity of the first shroud; the first coil sections (140, 142) (respectively) located in the first and around at least one of the second shroud; a ceramic arc tube (102) is located in the second cavity and includes first and second openings, first and second leads (104, 106) with electrodes, and for A lamp cavity (103) that seals the filler.

Description

technical field [0001] The present system relates to a ceramic discharge metal halide (CDM) lamp, and more particularly, to a high power CDM lamp with enhanced containment components and a method of manufacturing the same. Background technique [0002] As energy prices increase, inefficient light bulbs are being replaced with energy-efficient retrofit light bulbs that save power and provide enhanced light. Typical retrofit bulb types include Quartz Metal Halide (QMH), Ceramic Discharge Metal Halide (CDM), and others. Unfortunately, as will be discussed below, conventional CDM lamps are limited to specific applications and typically cannot be used as drop-in replacements, such as probe start ballasts, for existing lighting systems. Furthermore, as the wattage (wattage rating) of a CDM lamp increases, the bulb is sealed in the event of a failure (eg as illustrated by seal tests such as the overpowered American National Standards Institute (ANSI) seal test, etc.) and It is di...
