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

[0012] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0013] Such as figure 1 , figure 2 , image 3 and Figure 4 A standard lamp for detecting luminous intensity 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 filament 6 Both ends are respectively connected with two guide wires 7, the glass bulb 4 is spherical, the inner wall of the glass bulb 4 is blackened, and only a rectangular or square transparent tube is provided on the glass bulb 4 directly in front of the plane where the filament 6 is located. The light window 9, the length of the light-transmitting window 9 is 18-20mm, and the width is 18mm. A fixed seat 3 is connected between the two 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...

Abstract

The invention relates to a luminous intensity detection standard lamp comprising a lamp head and a glass housing. The glass housing is internally provided with a core column and lamp filaments. The glass housing is in a ball shape. The inner wall of the glass housing is painted black; and only the glass housing, right ahead of the plane where the lamp filaments locate, is provided with a rectangular or square light-transmitting window, wherein the length of the light-transmitting window is 18-20 mm, and the width is 18 mm. A fixation base is connected between two guide wires. The fixation base is provided with a plurality of molybdenum wire hook groups. Each molybdenum wire hook group comprises upper and lower two molybdenum wire hooks. The hook portions of the upper and lower two molybdenum wire hooks are in the same vertical line. The lamp filaments sequentially pass through the hook portion on the top of each molybdenum wire hook from left to right in a square-wave shape, and the lamp filaments are in the same plane. The lamp filaments are located right in the center of the light-transmitting window. The influence of reflection light from every direction on the glass housing is reduced; and the adjustment of the lamp filament is simpler, with just guaranteeing the filaments to be in the center of the light-transmitting window, thereby reducing the processing difficulty that the filaments must be in the center of the glass housing in the past.

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...
