SPOTLIGHT

Famous Spotlight, presented in the Mulier licht Katayaoga for 1999, p. 30.

The known searchlight comprises a hollow body in the form of a truncated pyramid framed by a frame on the side of the larger base, a light reflector located inside the body, a light source equipped with current-carrying fittings and made in the form of an incandescent lamp mounted in a cartridge mounted on a side wall inside the body, a translucent panel fixed in the frame of the case and made of heat-resistant silicate glass, a seal for attaching the panel in the frame in the form of an elastic profile gasket made of organosilicon zines, the bracket at the bottom of the housing for mounting the spotlight to the supporting surface, and a voltage source connected to the current supply of the light source fitting.

A disadvantage of the known searchlight is its inefficiency, due to the short service life of halogen incandescent lamps and their significant power consumption during operation of the searchlight. In addition, the operational capabilities of the spotlight are also limited, t. To. Each time, if it is necessary to increase the lamp power, it is required to use a different type of projector spotlight.

The closest in technical essence to the claimed is a Floodlights searchlight, presented: in the AMIRA catalog for 2000-2001, p. 57, 58 and selected as a prototype.

The known searchlight comprises a hollow body in the form of a truncated pyramid, framed on the side of the larger base with a frame fixed to it with a translucent panel and installed with the possibility of providing access to the inside of the body, a light source in the form of a cartridge installed inside the body.

a discharge lamp connected by means of a power supply fixture with a start-and-control device located inside the projector’s housing and connected to a voltage source, a light reflector located inside the housing, and a bracket in the lower part of the housing on its outer side for mounting the searchlight to a supporting surface.

A disadvantage of the known searchlight is its limited operational capabilities, which is due to the location of the start-regulating device inside the searchlight housing: this leads to the need to use the next standard size of the searchlight if it is necessary to use a more powerful or less powerful lamp.

The purpose of the claimed utility model is to expand the operational capabilities of the searchlight.

The goal is achieved by the fact that in the searchlight containing a hollow body in the form of a truncated pyramid, framed on the side of the larger base by a frame with a translucent panel fixed therein and installed with the possibility of providing access to the inside of the housing, the light source is installed in a cartridge mounted inside the housing , a discharge lamp connected by means of current-carrying fittings with a start-regulating device connected to a voltage source, a light reflector located inside the housing, and a bracket in the bottom parts of the housing on its outer surface for mounting the spotlight to the supporting surface, ACCORDING TO THE USEFUL MODEL, the ballast is made in a separate housing and is located outside the floodlight housing.

In this case, the cartridge for the lamp can be filled with an internal screw thread or plinth clamps inside.

Placing the trigger control device outside the spotlight housing allows you to replace it if you need to use a more powerful lamp or, conversely, a lamp of lower power, which extends the operational capabilities of the searchlight; the lampholder is easy to replace without damage to the structure as a whole. In comparison with the prototype, the claimed searchlight has a novelty, differing from it by such significant features as the implementation of the start-regulating device in a separate housing and its placement outside the searchlight housing, ensuring the achievement of a given result.

The inventive searchlight can be widely used in lighting technology as a lighting device for illuminating squares, building facades, architectural monuments, building sites and other open spaces and therefore meets the criterion of industrial applicability. The utility model is illustrated by drawings, which are presented on:

-Fig. 1 - general view of the spotlight,

-Fig. 2 is a sectional view of a spotlight

-Fig. For and 36 - lamp mounting options in the cartridge;

-Fig. 4 - scan reflector.

The searchlight (Fig. 1) contains a hollow body 1 in the form of a truncated pyramid, framed on the larger base side by a frame 2, in which, using a seal (not shown in the drawing), a translucent panel 3 of heat-resistant, for example, silicate glass, is fixed. Frame 2 can recline on housing 1 for the necessary lamp change. A light reflector 4 is placed inside the housing (Fig. 4), made in particular of high-purity aluminum — cellular or smooth. Inside the walls of the housing 1, a light source 5 is installed in the form of a discharge lamp, mounted in a cartridge 6, and equipped with

current-carrying fittings (not shown in the drawing) connected to a voltage source 7 through a start-regulating device 8, made in a separate corne and placed outside the housing 1 of the projector. The cartridge 6, depending on the power of the discharge lamp 5, can have inside spring clips for its fastening (for a low-power lamp, for example, 35 W) and be fixed symmetrically inside the housing 1 (Fig. 36) or have an internal screw thread (for a more powerful lamps - with a power of more than 70 W) and installed on one of the side walls of the housing 1. In the lower part of the housing 1, a bracket 10 is attached to it from the outside to attach the spotlight to the supporting surface (not shown in the drawing). The housing 1 can be molded, for example, from aluminum. The start-regulating device 8, made in a separate housing, can be electromagnetic (weight 3-4 kg) and can be installed separately from the searchlight at a distance of 1-10 m or electronic (weighing "200 g) and mounted next to the searchlight. The electronic control and starting device 8 is better used with low voltage quality to increase the life of the lamp 7. As a voltage source 7, in particular, an electrical network can be used.

The searchlight can be made as follows. The case 1 in the form of a truncated pyramid, in particular, is molded, for example, from aluminum. A light reflector 4, for example, made of high-purity aluminum, is inserted into the housing according to the corresponding scan. The reflector 4 can also be made in the form of a coating deposited on the inner surface of the housing 1. On one of the inner side walls of the housing 1, a cartridge 6 with a thread under the lamp 5 is installed in the opening of the housing and the reflector. For lamps 5 of low power, use the cartridge 6 in the form

spring clips mounted symmetrically inside the housing 1. A frame 2 is attached to the housing 1 from the larger base side, in which a translucent panel 3 made of heat-resistant glass is secured by means of a seal so that the frame 2 with the panel 3 can be tilted, allowing access inside the housing 1. The lamp 5 by means of current-carrying fittings is connected to a start-regulating device 8 located in a separate housing outside the housing 1 of the searchlight, which is connected to a voltage source 7.

The inventive floodlight can also be obtained by refining from a finished floodlight, such as described in the prototype, using a halogen incandescent lamp as a light source. Improvement in the latter case is as follows. The frame 2 is tilted, a halogen incandescent lamp 5 is inserted from the cartridge 6. The old cartridge 6 is removed, the hole for the new cartridge 6 is expanded to the desired size, then a new cartridge 6 is fixed under the discharge lamp 5, which, depending on the power, is screwed into the cartridge 6 or installed in it using spring clips (Fig. 3). The starting and regulating device 8 required for the lamp of the required power is installed in a separate housing outside the spotlight outside its housing 1, its input is connected to a voltage source 7, and the output is connected to the lamp armature 5.

In comparison with the prototype of the claimed searchlight has a wider operational capabilities.
