Abstract

The utility model relates to a lamp tube, which is made into a double-spiral type. The utility model adopts a fluorescent lamp with an orange yellow light lamp tube with the transmission of orange yellow light. After the lamp tube is started, the range of the wavelength of the emission peak is between 585 nm and 615 nm, and the lamp tube adopts rotation in the same direction, forming a double-head spiral. The utility model has the characteristics of reasonable lamp tube light distribution, stable emission of orange yellow light, compact structure, and convenient operation.

Description

Brown yellow color double helix fluorescent lamp

One, technical field:

The utility model relates to a kind of fluorescent lamp tube of brown yellow color, and especially related fluorescent lamp tube is a double helical form.

Two, background technology:

The light source of radiation brown yellow color is widely used in road lighting, parking lot illumination, floodlighting, security personnel's illumination, the dark place illumination of photographic industry, fields such as CRT chromoscope optical graving screen illumination.The light source of existing radiation brown yellow color mostly is and adopts low-pressure sodium lamp and straight pipe type brown yellow color fluorescent lamp.But, can move low-pressure sodium lamp to ' cold-zone ' because managing interior sodium ion during operation, make sodium air pressure decline in the pipe, argon ion is absorbed by arctube walls in causing managing, cause trigger voltage to improve, light output reduces, that is bigger variation can take place along with the burning-point time lengthening in light intensity and luminous flux, so low-pressure sodium lamp is applicable to the fields such as road lighting that color identifying requirement and illumination requirement are very not strict usually.Straight pipe type brown yellow color fluorescent lamp power has 20W, 30W and the several kinds of 40W, and wherein effect is preferably the long 40W fluorescent lamp of 1.2M, but straight tube (line) type light source volume is bigger, and there is inconvenience the installation aspect, and application also is restricted.So produced the compact fluorescent lamp that can exchange with incandescent lamp bulb, now the compact type lamp fluorescent tube that generally adopts is the above many U type fluorescent tube of U type, 2U type and 3U, increased single-screw type fluorescent tube afterwards again, but adopt the fluorescent tube of above-mentioned shape, its profile can't be done very for a short time, distribution of fluorescent tube light and transmittance are also unreasonable, so the fluorescent tube effect is relatively low.

Three, summary of the invention:

The utility model aims to provide a kind of radiation brown yellow color, and fluorescent tube light distributes rationally, and orange transmittance is stable, the fluorescent lamp with high light photoelectric transformation efficiency and contour structures compactness.

In conjunction with embodiment of the present utility model, existing that the utility model content introduction is as follows:

1, the utility model by brown yellow color fluorescent tube (1) (1a), oxide coated cathode (2), the tube chamber (3) that contains mercury and inert gas, stem stem (4), fluorescent material bisque (5), seal wire (6) (6a) etc. form.It is characterized in that fluorescent tube (1) is (1a) all by equidirectional rotation, form twin-feed spiral, helical type lamp (1) end connection (1a) communicates, fluorescent tube (1) other end (1a) respectively is equipped with oxide coated cathode (2), oxide coated cathode (2) links to each other with seal wire (6), and seal wire (6) (6a) places in the stem stem.

When the utility model starts at fluorescent tube, because negative electrode adds thermal electron, electron excitation mercury sends ultraviolet ray, and then excitated fluorescent powder sends visible light, sends orange coloured light behind the visible transmission brown yellow color fluorescent tube, and orange-yellow photopeak value wavelength is 600 ± 15nm, colour temperature Tc is 1930 ± 50K, red ratio R is 0.400 ± 0.05, and colour temperature coordinate x is 0.556 ± 0.1, and y is 0.440 ± 0.1.In addition, the utility model has adopted the double helix of the equidirectional coilings of fluorescent tube two ends, makes the more compact structure of fluorescent tube.

Since the orange coloured light of the utility model fluorescent-lamp-use brown yellow color fluorescent tube transmission, good reliability, good reproducibility; Adopted twin-feed spiral type fluorescent tube simultaneously, the light that has improved fluorescent tube distributes and transmittance, has improved the fluorescent tube effect, has dwindled the fluorescent tube volume again, is convenient to install and use.

Four, description of drawings:

Fig. 1 is the structural representation of the utility model brown yellow color double helix fluorescent lamp tube;

(1) is the brown yellow color fluorescent tube (1a) among the figure, and (2) are oxide coated cathode, and (3) for containing the tube chamber of mercury and inert gas, (4) are stem stem, and (5) are the fluorescent material bisque, and (6) are seal wire (6a).

Claims (2)

1. brown yellow color double helix fluorescent lamp, comprise by fluorescent tube (1) (1a), oxide coated cathode (2), the tube chamber (3) that contains mercury and inert gas, stem stem (4), fluorescent material bisque (5), seal wire (6) (6a) etc. form, it is characterized in that: fluorescent tube (1) is (1a) all by equidirectional rotation, form twin-feed spiral, helical type lamp (1) end connection (1a) communicates, fluorescent tube (1) other end (1a) respectively is equipped with oxide coated cathode (2), oxide coated cathode (2) links to each other with seal wire (6), and seal wire (6) (6a) places in the stem stem.

2. brown yellow color double helix fluorescent lamp according to claim 1 is characterized in that fluorescent lamp adopts the orange coloured light of brown yellow color fluorescent tube transmission.
