Abstract
The invention relates to a visible light excitation device of a fluorescent lamp. The conventional fluorescent lamp adopts mercury atoms in a mobile electron collision tube, which are generated in the discharging process, to emit ultraviolet rays; the ultraviolet rays irradiate fluorescent powder to emit visible light; and the method is greatly influenced by the temperature and has large environmental pollution. According to the invention, purple light LEDs are arranged on stems at both ends in a lamp tube by adopting a special process; and the purple light LEDs are adopted to emit purple light to excite the fluorescent powder to emit the visible light. The visible light excitation device has the advantages of high luminous efficiency, long service life, good color rendering property, soft color, no pollution and the like.
Description
Technical field
The present invention relates to a kind of LED power saving fluorescent lamp, particularly a kind of manufacturing process with luminous excitation material in the alternative existing fluorescent lamp of purple LED belongs to lighting technical field.
Background technology
Along with various new materials, new technology are constantly applied at lighting field, use fluorescent lamp tube cell, stem stem, filament, electronics powder, mercury power saving fluorescent lamp as main material, obtained the approval of all power saving fluorescent lamp producers and used comprehensively.The structure of this fluorescent tube is: at the two ends of different shape glass tube (spirality, U-shaped, H shape, straight tube shape, annular, D shape and all kinds of abnormity) or multiterminal melt and sealed one or more wicks, form the prerequisite of visible light as excitated fluorescent powder under vacuum state with this.Its feature is: in glass tube, be filled with the argon gas of easy discharge and the mercury of minute quantity, on the glass-tube inwall, be coated with fluorescent material, useful tungsten filament is made on the two ends wick of pipe two spirals or triple helical tungsten wire ring electrode; On electrode, be coated with the material of emission electronics; Under the vacuum "on" position, when lighting a lamp (startup), electric current flows through electrode and heating; From filament towards the interior thermoelectron of launching, and begin the discharge.Ultraviolet ray (253.7
takes place with the collision of the mercury atom in the pipe in the mobile electron of discharge generation).This ultraviolet ray irradiation fluorescent material becomes visible light.Along with the kind of fluorescent material is different, can send diversified photochromic.Thereby people's illumination needs have farthest been satisfied.But this fluorescent lamp can cause the variation of brightness because of variation of ambient temperature.This is because the cause that the vapour pressure of mercury changes with the variation of environment temperature in the glass tube: 1. if mercury vapor is pressed to be changed, then ultraviolet generation efficient changes, and luminous flux also changes thereupon.2. enclose the pressure of gas and the pressure ratio of mercury vapor and change, thereby starting characteristic also changes.Also have the light velocity characteristic that goes down: 1. fluorescent lamp reduces luminous flux because of melanism and fluorescent material deterioration etc. in the process of lighting a lamp simultaneously gradually.2. the coefficient of losses power of lamp does not almost change.3. various types of lamp is difference to some extent, the big more lamp of tube wall load (power of per unit area), and luminous flux goes down big more.4. in addition, the degradation of various fluorophor is different, and by the three-color fluorescent lamp of 3 ~ 4 kinds of fluorophor mixed luminescences, when brightness reduced, it is photochromic also to have some variations.But color rendering is almost constant.Although the production technology of all power saving fluorescent lamp producers is more or less the same; In actual mechanical process since the amount of mercury, argon gas, electronics powder control fine still difficulty very; This has just caused the quality of each manufacturer uneven, the loss of the mercury that the damage of the fluorescent tube in production operation and user's use and the life problems of lamp form thereby cause environmental pollution.So whether there is other lamp manufacturing process can replace existing manufacturing technique, thereby can eliminates the lamp manufacturing process that easily environment is polluted.
Summary of the invention
The object of the present invention is to provide a kind of purple light excited LED electricity-saving lamp; It is luminous with the purple LED excitated fluorescent powder; Thereby substituted traditional electronics powder and excited mercury, mercury sends the relatively low fluorescent lamp manufacturing process of high pollution life-span of purple light excited light-emitting phosphor.
To achieve these goals, technical scheme of the present invention is: it has the glass-tube of fluorescent material, stem stem to constitute by purple LED, coated inner wall, and said purple LED places on the said stem stem in the interior two ends of fluorescent tube.Violet wavelength that said purple LED sends be 253.7
.Its manufacture craft is: 1, get wavelength and be 253.7
purple LED; 2, above-mentioned purple LED is connected on the stem stem; 3, place coated inner wall that the glass-tube of fluorescent material is arranged the above-mentioned stem stem that is provided with purple LED, 4 encapsulate step 3 resulting part.
The present invention has the source efficiency height, and the life-span is long, good economy performance, and color rendering is good, and photochromic abundant, applied widely, light-emitting area is big, and shade is few, advantages such as environmental protection.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
In the accompanying drawings: 1, energising seal wire, 2, superconduction thermal conductance silk, 3, steam vent, 4, the heat conduction pin, 5, purple LED, 6, glass tube, 7, fluorescent material.
The specific embodiment
Shown in accompanying drawing, select for use purple LED 5 to become the raw material of visible light as the fluorescent material on the irradiation glass inwall among the present invention.Purple LED 5 is made single of specified wavelength (be generally 253.7
) or many need are made bar type, be welded on the energising seal wire 1 in the wick column of appointment.The LED cooling pad is through heat conduction pin 4,2 heat radiations of superconduction thermal conductance silk.Steam vent 3 is in the exhaust apparatus of working under the vacuum state for purple LED 5 at fluorescent tube, and fluorescent material 7 is coated on glass tube 6 inwalls, and the UV-irradiation that purple LED 5 energisings are sent inspires visible light on fluorescent material 7.Wick is that glass material is convenient to melt envelope with fluorescent tube among the present invention.The illumination advantage of LED and fluorescent lamp has been merged in the present invention, has realized high light efficiency, the life-span is long, colour rendering good, color is soft, pollution-free purpose.Example: making power is the fluorescent lamp of 7W, gets the glass-tube that inwall scribbles fluorescent material, the wick that the purple LED of two 1W will be housed melts on the two ends that are enclosed in glass-tube, and purple LED sends purple light after the energized, utilizes the light-emitting phosphor of purple light excited glass-tube inwall.Usually the wavelength that sends of purple LED be 253.7
best to light powder stimulation effect.Through combinations thereof and compound mode, can produce replacement mercury excited fluorescent lamp.
