Abstract
The utility model discloses an energy-saving internal-reflection fluorescent tube which comprises a glass tube, a core column, a filament and a lamp holder, wherein the glass tube is filled with mercury steam and inert gas, and the inner wall of the glass tube is sequentially provided with a reflecting layer and a phosphor coating. The energy-saving internal-reflection fluorescent tube is excellent in light reflection and energy saving effects.
Description
Technical field
The utility model belongs to the electric light source technology field, particularly relates to a kind of internal reflection energy-saving fluorescent lamp.
Background technology
Existing fluorescent tube great majority are 360 ° of emission light, as strengthening the illumination of effective area, then fluorescent tube must be installed in the light fixture with good reflection effect.CN 2186442Y discloses a kind of fluorescent tube, it has the mercury coating with certain width on the fluorescent tube outside, and at mercury coating covering one deck sealing wax, this mercury coating is equivalent to a concave mirror, luminescence center is just on the focus of this concave mirror, the mercury reflecting surface to the pipe internal reflection, has strengthened effective illumination with light, reaches energy-conservation purpose.Yet, no matter be by the light fixture reflector or utilize the tube outer wall reflecting surface to come reverberation, all can only the reflecting part light splitting, as visible light, and can not realize to wavelength being the reflection of light of 253.7nm, therefore its reflecting effect is not satisfactory, and effectively the enhancing of illumination is also very limited, and energy-conserving action is not obvious.CN2580598Y discloses a kind of power saving fluorescent lamps, it is that glass-tube at fluorescent tube arranges special coating by the corresponding inwall of central angle alpha, described special coating has good reflex to light, can reflection wavelength be the light of 253.7nm particularly, can improve luminous intensity, increase effective illumination, energy-conservationly reach 30%.Yet experience is told us, and such result is far from satisfying.In electric light source research is made, the energy-saving and cost-reducing eternal target that must become pursuit of product.
Summary of the invention
The purpose of this utility model provides a kind of internal reflection energy-saving fluorescent lamp, and its light reflecting effect is better, and energy-saving effect is better.
The technical solution of the utility model is that a kind of internal reflection energy-saving fluorescent lamp comprises glass-tube, stem stem, filament and lamp holder, is filled with mercury vapor and inert gas in the glass-tube, it is characterized in that: described glass-tube inwall is provided with reflector and fluorescent coating successively.
As a kind of preferred, described reflector is arranged at glass-tube by on the corresponding inwall of central angle alpha; Described fluorescent coating is arranged on the whole inwall of glass-tube.
As a kind of preferred, described central angle alpha is 180 ° ~ 200 °.
The utility model at first is coated with the reflection powder at glass-tube by the corresponding inwall of central angle alpha, and the reflector namely is set, and is not coated with reflection powder place again and is coated with layer of fluorescent powder in the whole glass-tube on reflector and glass-tube, and fluorescent coating namely is set.It can reflection wavelength be the light of 253.7nm, its principle is: the fluorescent material of the ultraviolet ray excited whole glass-tube inwall of the 253.7nm of incident, the visible light that fluorescent material is produced shines out to that side of not establishing the reflector by the concentrated area, reflector of glass-tube one side again.The utility model coating structure is adapted to various low-pressure gaseous discharge lamp pipes.
In the utility model, described reflector can be selected titanium dioxide for use.
The utility model is that the glass-tube inwall is provided with reflector and fluorescent coating successively, namely is coated with reflection earlier and is coated with fluorescent material behind the powder.The good reflection that it has been realized light comprises to wavelength being the reflection of light of 253.7nm, under the suitable prerequisite of total light flux, with respect to not establishing reflector fluorescent tube energy-saving effect up to more than 50%; With respect at the glass-tube inwall fluorescent tube that fluorescent coating arranges the reflector again being set earlier, energy-saving effect reaches more than 15%.
