摘要： The concave reflecting surface of a projector lamp reflector is shaped in the form of a plurality of radial bands and a plurality of concentric circular bands to provide a multiple faceted surface for spreading the image formed by the reflector into a larger and smoother pattern and reducing the amount of imaging of a lamp filament and support post in the projected light pattern. Longer life and improved reproducibility of the molding tool are achieved.

摘要： A compact lamp unit and associated socket for use in a projection system such as a slide projector, microfilm viewer, and so forth. The lamp unit includes a reflector molded from a plastic material and an electric lamp secured within the reflector. In order to decrease the axial dimension of the reflector and to avoid the use of pin connectors, electrical contacts for the lamp are pressed into recesses formed in the outer surface of the reflector. The reflector includes an opening at its apex through which electrical leads from the lamp extend outwardly of the reflector. The electrical leads are secured to the contacts by being forced into the recesses along with the contacts. This construction technique is fast and simple.The lamp unit also includes a handle to enable a heated lamp unit to be replaced by the user and a guide means to enable the lamp unit to be oriented quickly and accurately upon insertion into the socket. In their preferred forms, the handle and the guide means are identically configured and comprise fins extending outwardly of the convex surface of the reflector, the fins lying on opposite sides of the opening and in the same plane.The socket into which guide means is inserted includes a first upstanding member defining a reference plane against which a portion of the reflector is engaged in use. A second upstanding structure engages another portion of the reflector to securely retain the reflector when it is inserted into the socket. The socket includes a pair of flexible contacts engageable with the contacts carried by the lamp unit, the socket contacts being positioned in a plane substantially parallel with the reference plane. When the lamp unit is inserted into the socket, the socket contacts are flexed sufficiently to make good electrical contact with the contacts carried by the lamp unit. A retention mechanism in the form of a flexible bail may be used to prevent inadvertent displacement of the lamp unit from the socket.

摘要翻译： 用于投影系统（例如幻灯投影仪，微缩胶片观看器等）中的小型灯单元和相关插座。 灯单元包括由塑料材料模制的反射器和固定在反射器内的电灯。 为了减小反射器的轴向尺寸并避免使用针连接器，灯的电触点被压入形成在反射器的外表面中的凹槽中。 反射器包括在其顶点处的开口，来自灯的电引线通过该开口延伸到反射器的外部。 通过与触点一起被迫进入凹部，电引线固定到触点。 这种施工技术快速简单。 灯单元还包括手柄，以使得用户可以更换加热的灯单元，以及引导装置，以便在插入插座时使灯单元能够快速且准确地定向。 在其优选形式中，手柄和引导装置相同地构造并且包括从反射器的凸表面向外延伸的翅片，翅片位于开口的相对侧并位于同一平面中。 引导装置插入其中的插座包括限定反射器的一部分在使用中与其接合的参考平面的第一直立构件。 第二直立结构接合反射器的另一部分，以便当反射器插入插座时牢固地保持反射器。 插座包括可与灯单元携带的触点接合的一对柔性触点，插座触头位于基本平行于基准平面的平面中。 当灯具单元插入插座时，插座触点被充分弯曲，以使与灯单元承载的触点良好的电接触。 可以使用柔性吊环形式的保持机构来防止灯单元从插座中的意外移位。

摘要： Electrodes for a single ended arc discharge tube in which the electrodes diverging from the foil leads are generally concave towards each other between the lead-in wire ribbons and the free ends thereof from which the arc is drawn, the electrodes being spaced apart a greater distance at the point of entering the envelope than the distance between the ribbons.
