Problems solved by technology

At present, typical standard lamps for luminous intensity detection are generally only composed of bulbs and lamp holders. Stray light has a great influence, and it is difficult to obtain stable and uniform light intensity values. Some standard lamps for luminous intensity detection use Too complex structure increases production cost

Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments:

[0012] like figure 1 , figure 2 and image 3 The shown standard lamp for detection includes a lamp cap 1 and a glass bulb 4. The glass bulb 4 is provided with a stem 2 and a filament 6. Two guide wires 7 are drawn from the stem 2. The ends are respectively connected with two guide wires 7. When the lamp cap 1 is on the bottom and the glass bulb 4 is on the top, the lamp is in the shape of a rounded cone or a rounded truncated cone as a whole, and the upper end face of the glass bulb 4 is an arc surface; the two A fixed seat 3 is connected between the guide wires 7, and several molybdenum wire hook groups are arranged on the fixed seat 3. Each molybdenum wire hook group includes two high and low molybdenum wire hooks 5. The hooks of the two high and low molybdenum wire hooks 5 The parts 8 are in the same vertical line, and the fila...

Abstract

The invention relates to a standard lamp for detection. The standard lamp comprises a lamp cap and a glass bulb. A stem and lamp filaments are arranged in the glass bulb. Two guide wires are led out from the interior of the stem. The two ends of the lamp filaments are connected with the guide wires respectively. The upper end face of the glass bulb is of an arc-face back taper shape. A fixing base is connected between the two guide wires and provided with a plurality of molybdenum wire hook sets. Each molybdenum wire hook set comprises a high molybdenum wire hook and a low molybdenum wire hook. The hook portion of each high molybdenum wire hook and the hook portion of each low molybdenum wire hook are located on the same vertical line. The lamp filaments sequentially penetrate through the hook portions of the tops of the molybdenum wire hooks from left to right according to a square wave shape, and are arranged on the same plane. The standard lamp reduces influence of stray light, avoids the processing difficulty that the influence of the lamp filaments is reduced on the condition that the lamp filaments are located in the center of the glass bulb when the spherical glass bulb is adopted, and improves the qualified rate.

Description

technical field [0001] The invention relates to a lamp, in particular to a standard lamp for luminous intensity detection. Background technique [0002] The luminous intensity detection standard lamp is used to reflect and transmit the value of the luminous intensity unit (candela cd), and is an important standard instrument in the measurement of optical radiation. The luminous intensity detection standard lamp is generally made of incandescent lamp or tungsten halogen lamp. In order to make the filament the only illuminant of the luminous intensity detection standard lamp, the stray light of the glass bulb and other filament supports should be minimized. At present, typical luminous intensity detection standard lamps are generally only composed of bulbs and lamp sockets. The influence of stray light is large, and it is difficult to obtain a stable and uniform luminous intensity value. In order to reduce the influence of stray light, some luminous intensity detection standar...
