RU216458U1 - Ceiling lamp based on gas discharge lamp - Google Patents

Abstract

The proposed utility model relates to lighting engineering, in particular to stationary ceiling lamps based on a high-pressure gas discharge lamp as the main light source. Ceiling luminaire based on a metal halide discharge lamp is designed for rooms with high requirements for light distribution of lighting equipment, such as living quarters, offices, libraries, etc. The claimed utility model is the main element of the lamp housing, which determines the light pattern from the lamp. Due to the use of a tubular bracket with a lamp vertically located on its lower platform, the light distribution has an almost spherical radiation pattern. The body of the lamp is made of metal. 2ill.

Description

The proposed utility model relates to lighting engineering, in particular to stationary ceiling lamps based on a high-pressure gas discharge lamp as the main light source. The luminaire is designed to illuminate rooms with increased requirements for light distribution, such as living quarters, offices, libraries, educational institutions, etc.

Luminaires based on gas-discharge metal halide or sodium lamps are known from the prior art, which are used to illuminate architectural objects, streets, industrial facilities, retail premises, greenhouses, etc., characterized in that they have a utilitarian housing in which a reflector, cartridge lamps and electronic ballast. The lamp and the reflector of such a lamp are usually covered with protective glass. Such luminaires are installed using a bracket on the floor, walls or ceiling of rooms or other objects. The bracket arrangement usually allows the luminaire to be tilted.

In addition, there are street lighting lamps with a circular hemispherical luminous flux, and a structure closed by one or more protective glasses.

Despite the obvious advantages of the latest generation of metal halide lamps, such as high light quality, similar to incandescent halogen lamps, long service life up to 20,000 hours, high color rendering index, high light output up to 120 lm / W, as well as high power of one lamp at a relatively small size, such lamps until now have practically not received any other application, except for commercial, industrial and architectural. This is facilitated by a number of shortcomings of metal halide lamps, their electronic ballasts and luminaire housings of such lamps. These disadvantages include directional light from such fixtures due to the use of a reflector. Also known fixtures that partially solve the problem of the proposed technical solution, for example RU18296U1, publ. 06/10/2001 or RU142628U1, publ. 06/27/2014 using other types of light sources, for example, based on LEDs, having a number of disadvantages, in particular, the impossibility of creating a compact high-power point light source due to the design of the light source and the problem of heat dissipation. For a similar reason, it is not possible to use halogen incandescent lamps due to their high heat and low energy efficiency of less than 26 lm/W.

The task to be solved by the claimed technical solution is to create a distribution of light flux close to spherical from a point source.

This task is achieved due to the fact that the luminaire housing includes a vertical tubular bracket 1, on the lower platform of which there is a cartridge 2 with a gas-discharge metal halide or sodium lamp 3 located vertically, the base down and a protective cover 4 lamps made of a quartz or glass heat-resistant tube with In this case, the upper end of the tube of the protective cover is plugged with a diffuser 5.

The technical result provided by the above set of features is a close to spherical distribution of the light flux, with the exception of shadows from the body elements.

Implementation Details

At the moment, design documentation and manufacturing technology for the claimed utility model have been developed. Prepared for small-scale production. This technology has already made several copies of lamps that are undergoing long-term testing in residential premises. The test specimens used third-generation metal halide lamps with a service life of more than 15,000 hours, a power of 70 and 150 W and a light output of 7,800 and 17,500 lm, respectively. The light of the proposed utility model is comparable to the light of halogen incandescent lamps and significantly improves the efficiency and quality of perception of details and textures of surfaces in comparison with LED lighting sources with equal power consumption.

Claims (1)

A luminaire characterized in that the housing includes a vertical tubular bracket, on the lower platform of which there is a cartridge with a gas-discharge metal halide or sodium lamp located vertically, with the base down, and a protective lamp shade made of a quartz or heat-resistant glass tube, while the upper end of the tube of the protective lamp muted diffuser.
