Note 1 |
||
To obtain the most accurate centering of the light beam of the reflector in the frame window, the centering principle shown in the figure is recommended.
Notes (edit)
1 The L dimension defines the distance between the lamp mounting surface and the frame plane.
2 The spring arrangement must be such that the edge of the reflector, regardless of its thickness, is pressed against the bottom and the mounting surface. The lamp reflector is pressed against the mounting surface or three base protrusions. The socket is provided with a base slot for inserting the base projection of the lamp to prevent it from rotating.
3 To reduce the axial displacement, the lower fixing point must be pressed against the edge of the fixing plane. This can be achieved by shaping the upper spring such that the edge of the reflector is pressed to the side rather than forward so that the opposite edge of the reflector is positioned on the mounting surface.
Dimension £, the space between the mounting plane and the optical axis of the projector, is considered an objective value.

REFLECTOR DIAMETER 50.8 MM AND CASE GX5.3 OR GY5.3 |
1 Types of fastening systems
a) push plug system
The lamp is fully attached to the edge of the reflector using a flexible electrical plug.
b) double-sided flexible fastening system
A complex device that provides fastening at both ends of the lamp.
2 System elements
2.1 Lamp sizes
Detailed dimensions for 2-inch one-piece reflector lamps are given in sheet 60357-IEC-1005. An accurate check of some of these dimensions is necessary to ensure proper operation of the two-way flexible attachment system.
2.2 Plinth dimensions
The dimensions of the GX5.3 and GY5.3 base / plinths are given in IEC 60061-1. It should be noted that it can be difficult to insert lamps with a socket with a maximum pin length of 7.62 mm.
2.3 Bezel centering devices
Sheet 60357-IEC-1004 specifies two methods for centering the reflector rim in the mounting system. They differ as method 1 (general method) and method 2 ( exact method). In each case, with any attachment system, a rim centering device can be used. Either of the two rim centering devices can be used with any mounting system.
2.4 Plugs and contact assemblies
The dimensions of the plugs and / or contact assemblies when used in these attachment systems are under consideration.
2.5 Ancillary attachment devices
As noted in 3 and 4, some variations of these attachment systems may require additional methods. mechanical fastening or force so that the edge of the reflector is pressed directly against the base surface of the rim-centering device. Details of such devices are not indicated for the possibility of free choice of design, while there should be no contradiction with standardized dimensions.
3 Push plug system
The bezel centering device allows the lamp to be positioned and guided when a spring or similar element holds the bezel of the lamp on the base surface of the centering device. The electrical connection is provided with a flexible cord plug. This system is designed to mount the lamp by simply sliding it towards the mechanical stop and base surface, and then slide the plug onto the base or vice versa.
4 Double-sided flexible mounting system
The double-sided system is a device that secures the reflector and lamp base. The rim centering device provides the initial attachment and functional position of the reflector rim. Booster springs or similar may be required to provide additional holding force. The contact assembly at the end of the base / plinth has two functions: provides electrical contact and secures. This system serves to insert the lamp by simply sliding it to the position of the reflector rim in the mechanical stop and the base surface while simultaneously inserting the pins of the base into the recesses of the contact assembly.
For a two-way flexible mounting system, the contact assembly must be able to move slightly in the direction of the lamp axis relative to the reference surface of the bezel-centered device. This movement allows the entire length of the lamp to be positioned in its normal operating position. Dimensions N-1 and L / 2 define the boundaries of this movement.
The attachment for the contact assembly can be designed to provide both partial and full ultimate compression so that the bezel of the reflector is pressed against the bezel-centered device. Springs or the like can be used to provide this ultimate force. The bearing surfaces of the contact assembly and lamp base are surfaces referred to as the "Z surface" for each part. Desirably, the surface Z of the socket of the socket has an entry angle at the edge where the surface Z of the base enters when the lamp is inserted.
The contact assembly can be located on a corresponding protrusion, allowing full insertion of the lamp up to the stop of the device, centering the rim, and ensuring contact with the pin of the base. The contact assembly or its contacts should move slightly in a plane perpendicular to the lamp axis to allow for some misalignment in the position of the lamp pins relative to the center of the device, centering on the bezel.
The contact assembly of the cartridge can be designed in two forms, depending on the applied voltage:
a) two pins simultaneously enter two corresponding grooves of the contact assembly;
b) both pins of the base fit into the same groove and the two contacts are positioned one above the other in their respective places.
Details of these contact assemblies are given in the lampholder standard (under consideration).
5 Acceptance control
The use of gauges to test these two types of fastening is under consideration.
For some lamps, the H dimension is given from the top of the filament. For dimensions, refer to the appropriate lamp data sheet.
BODY INCREASE REQUIREMENTS
Definitions (see page 1)
The base axis of the lamp is a line passing through a point in the middle between the axes of the pins when they exit the blade and through a point in the middle between the axes of the ends of the pins.
Lamp reference plane - the plane passing through the end of a pin corresponding to the full length of the pin and perpendicular to the reference plane.
In the front view, the line defining the filament generally forms a trapezoid. The height of the filament body (/?) Is the perpendicular between the parallel sides of the trapezoid. The width of the filament body (co) is the distance between the intersections of the center line of the parallel sides with the non-parallel sides of the trapezoid.
The height of the light center of the lamp (H) is the perpendicular between the reference plane and a parallel plane passing through the center or through the upper point of the filament in front view.
The front view of the filament body (A) is the perpendicular between the reference axis and the outside of the filament body.
The inclination of the filament body in the side view (a) is the angle between the parallel sides of the trapezoid and the reference plane.
Requirements
The values for the dimensions of the filament and its position indicated on the corresponding lamp data sheets apply to the filament under rated voltage. They are checked by the template system on p. 3. (These figures show the actual dimensions of the filament. As an exception for the angle a, these values can be multiplied by the appropriate factor.)
The image of the filament must be projected onto the fixed elements of the template system with the correct positioning of the reference axis and plane.
In the front view, the concentric movable contour templates should move until the filament image is symmetrical in these templates. Then apply the following:
The filament image must not be less than the inner contour template and larger than the outer contour template, an exception is allowed for the lower half of the outer template, when the image may overlap with vertical lines;
The center point M of the contour templates (or the top point T if the H dimension is given from the top of the filament body) must be within the fixed template in the front view;
The slope of the contour templates should be no more than the slope given for the fixed grid lines in the front view.
In the side view, the image of the filament should be located between fixed parallel lines.

Notes (edit)
1 Dimension L (working distance) is the distance from the seating surface (surface x) to the plane of the frame. This value depends on the objective lenses used as well as the contour of the lamp reflector. See lamp data sheets for specific values.
2 The shape of the device is not limited to that shown. Notches, bolts or other locking elements must be provided in the specified sheets.
3 The centering device is intended for use with a retention system that provides an axial force to bring the surface of the lamp rim into contact with the surface x of the device. This device provides the primary placement and holding function of the lamp.
