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

[0009] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0010] Such as figure 1 A standard lamp shown includes a lamp cap 1, a glass bulb 4, a stem 2 and a filament 6 are arranged inside the bulb 4, two guide wires 7 are drawn out of the stem 2, and the two ends of the filament 6 are respectively Connected with two guide wires 7, the glass bulb 4 is spherical, and a fixed seat 3 is connected between the two guide wires 7, and several high and low molybdenum wire hooks 5 are arranged on the fixed seat 3, and the filament 6 Pass through the hook portion 8 on the top of the molybdenum wire hook 5 sequentially from left to right, the filament 6 is distributed in an M shape, and the filament 6 is all on the same plane, and the distance from the plane to the front and rear glass bulbs 4 is equal, so The distance from the left end of the filament 6 to the left glass bulb 4 is equal to the distance from the...

Abstract

The invention relates to a standard lamp. The standard lamp comprises a lamp cap and a glass shell, wherein a core column and a lamp filament are arranged in the glass shell; two guide wires are led out of the core column; the two ends of the lamp filament are connected with the two guide wires respectively; the glass shell is spherical, a fixing base is connected between the two guide wires; a plurality of molybdenum wire hooks alternating high and low are arranged on the fixing base; the lamp filament penetrates through hook parts at the tops of the molybdenum wire hooks sequentially from left to right; the lamp filament is distributed in an M mode and located at the same plane; the distance between the plane and the front portion of the glass shell and the distance between the plane and the rear portion of the glass shell are equal; the distance between the left end of the lamp filament and the left side of the glass shell and the distance between the right end of the lamp filament and the right side of the glass shell are equal. The glass shell is spherical, the lamp filament is arranged in the right center of the glass shell, reflection light of the lamp filament in various directions of the glass shell coincides at the lamp filament, influence of stray light is reduced, and the light emission stability of the lamp filament is strengthened.

Description

technical field [0001] The invention relates to a lamp, in particular to a standard lamp for detecting luminous intensity. Background technique [0002] The standard lamp for luminous intensity detection 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 light radiation. Standard lamps for luminous intensity testing are generally made of incandescent lamps or tungsten halogen lamps. In order to make the filament the only illuminant of the standard lamp for luminous intensity testing, stray light from glass bulbs and other filament supports should be minimized. At present, typical standard lamps for luminous intensity detection are generally only composed of bulbs and lamp holders, and stray light has a greater impact, and it is difficult to obtain stable and uniform light intensity values. Some standard lamps for luminous intensity detection use An overly complex structure incr...
