Abstract
The utility model relates to an electromagnetic induction lamp, which belongs to the field of energy saving products. The low radiation electromagnetic induction lamp comprises an electromagnetic induction lamp body and a shell covering the electromagnetic induction lamp. The shell of the electromagnetic induction lamp is fully sealed. A group of closing coils is respectively arranged at the top and bottom of the shell of the electromagnetic induction lamp. The two groups of closing coils are completely same and winded by same copper wires in same number of turns, same winding direction and same coil diameter. In the utility model, same closing coils are further arranged at the top and bottom of current electromagnetic induction lamp and when the inner coils inside the electromagnetic induction bulb are electrified, an alternating magnetic field is formed. Outside closing coils further form a magnetic field to impede the variation trend of the primary magnetic field according to Lenz's law. Thus, the electromagnetic radiation outside the electromagnetic induction bulb is impeded and external electromagnetic radiation is reduce, thereby the utility model reduces the damage to human and is safe, energy saving and environmental friendly.
Description
Technical field
The utility model relates to a kind of electromagnetic induction lamp, relates in particular to a kind of electromagnetic induction lamp with low radiation.
Background technology
Energy-conservation and environmental protection is the two principal themes of current social development, also is the inexorable trend of social development.The electromagnetic induction lamp of no filament electrode arises at the historic moment, and its invention is a huge revolution for lighting industry.
The operation principle of electromagnetic induction lamp is:
Electromagnetic induction lamp does not have electrode, therefore claims that again it is electrodeless lamp.Since it does not lean on filament and electrode light-emitting, what is its principle of luminosity so? In fact, what its relied on is electromagnetic induction principle, mainly by a hollow discharge bulb, and coupler and radio-frequency generator composition.Behind the supply voltage of input certain limit; Radio-frequency generator produces the 2.65MHZ high frequency voltage and gives power coupler, in the discharge space of glass bulb, sets up high-frequency alternating magnetic field (magnetic field that promptly changes produces induced current, utilizes coupling concussion principle that the high frequency voltage that produces is injected in the glass tube of vacuum again) by power coupler; According to Faraday's electromagnetic induction law; The magnetic field that changes can produce induced current in fluorescent tube, cause the acceleration of free electron, thereby makes the mixed vapour of low-pressure mercury and inert gas produce discharge; And giving off strong ultraviolet light, the three primary colors fluorescent powder of glass inner wall receives strong uv light induction and is luminous.
The characteristics of electromagnetic induction lamp and deficiency:
Based on above-mentioned principle, with the comparison of other electricity-saving lamps in, electromagnetic induction lamp just has many advantages.
(1) energy-efficient.Its power factor is very high, generally about 0.98, than common energy-saving lamp economize on electricity 45%, than incandescent lamp economize on electricity 80%.In addition, luminous efficiency also reaches 80-85lm/w, belongs to high light efficiency.
(2) environmental protection.Adopt solid-state amalgam and no soda-lime glass, and apply materials can repeated application more than 98%.
(3) long-life.Because electromagnetic induction lamp does not have electrode; Thereby effectively avoided the loss of electrode burning-point; Life-span generally can reach more than the 60000h, than long about 100 times of ordinary incandescent lamp, also will exceed more than one times compared with the wider high-pressure sodium lamp of present application (the general life-span is 28000h).
(4) high-color rendering, free from glare, flicker free.Adopt three primary colors fluorescent powder, color rendering index makes can effectively help driver and pedestrian to differentiate various objects by the Well-recovered of color at night greater than 80.
(5) wide region of lamp power and supply voltage.Power scope of application 20-250w, voltage scope of application 85-250v has good versatility and stability.
Certainly electromagnetic induction lamp also exists other plurality of advantages, and high with coefficient such as the light tonneau, penetration capacity is strong or the like.
Electromagnetic induction lamp has brought many advantages, but also exists not enough.The most important thing is its electromagnetic radiation and electromagnetic interference problem.The magnetic field that changes at a high speed will certainly produce strong radiation, and radiation will inevitably produce harm to human body, if use electromagnetic induction lamp on a large scale, how effectively reducing radiation is the very important problem that need solve.
Summary of the invention
The utility model technical problem to be solved provides a kind of low electromagnetic radiation sense light, thereby solves present electromagnetic induction lamp because radiation has the defective that harm can't be promoted the use of on a large scale to human body strongly.
Technical scheme
A kind of low electromagnetic radiation sense light; The electromagnetic induction lamp housing that comprises the electromagnetic induction lamp body and cover outward; Said electromagnetic induction lamp housing is totally-enclosed, it is characterized in that: top and bottom at said electromagnetic induction lamp housing are separately installed with one group of closing coil, and two groups of closing coils are identical; Be entwined by identical copper cash, and the number of turn of twining is identical, around to identical, coil diameter is identical.
Said two groups of closing coils are for being symmetrical set up and down.
The central point of said two groups of closing coils lays respectively on the central point of said electromagnetic induction lamp housing top and bottom.
The diameter of said closing coil greater than 2 times of electromagnetic induction lamp Inside coil diameter and more than.
The length of said electromagnetic induction lamp housing is wide 2～3 times.
Said electromagnetic induction lamp housing is a cylinder, and said cylindrical electromagnetic induction lamp housing top and bottom are separately installed with the crown top of burner, and said closing coil is fixed in the said crown top of burner.
Beneficial effect
The electromagnetic induction lamp of the utility model is provided with identical closing coil on existing electromagnetic induction lamp top with the bottom increase; After electromagnetic induction bulb Inside coil energising work; Form an alternating magnetic field, according to Lenz's law, the closing coil of outside also can form a magnetic field and hinder original changes of magnetic field trend; So just can effectively hinder the outside electromagnetic radiation of electromagnetic induction bulb; Reduced outside electromagnetic radiation, become the electromagnetic induction lamp of low radiation, safety, energy-conservation environmental protection again.
Description of drawings
Fig. 1 is existing electromagnetic induction lamp schematic diagram.
Fig. 2 is the utility model sketch map.
Wherein: 1-electromagnetic induction lamp housing, the 2-closing coil, the 3-crown top of burner, the 4-power coupler, 5-fluorescent material, the 6-center cavity, the 7-main mercurial, 8-assists mercurial.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing, further set forth the utility model.
Be depicted as the principle schematic of existing electromagnetic induction lamp like accompanying drawing 1; Behind the supply voltage of input certain limit; Radio-frequency generator produces the 2.65MHZ high frequency voltage and gives power coupler 4, in the discharge space of electromagnetic induction lamp housing 1, sets up high-frequency alternating magnetic field by power coupler 4, and the magnetic field of variation produces induced current in fluorescent tube; Cause the acceleration of free electron; Thereby the mixed vapour that makes low-pressure mercury that main mercurial 7 and auxiliary mercurial 8 produce and inert gas produces and discharges, and gives off strong ultraviolet light, and the three primary colors fluorescent powder 5 of electromagnetic induction lamp housing 1 inwall receives strong uv light induction and luminous.Luminescence process is followed magnetic field, and radiation is very strong.
