Abstract
The invention discloses an energy-saving fluorescent lamp capable of internal reflection. The lamp comprises a glass-tube, a core column, lamp filaments and lamp heads. Mercury vapour and inert gas are stuffed in the glass-tube, and a reflecting layer and a fluorescent powder layer are sequentially arranged on the inner wall of the glass-tube. Therefore, the lamp is better in light reflection effect and in energy-saving effect.
Description
Technical field
The invention belongs to electric light source technology field, particularly relate to a kind of internal reflection energy-saving fluorescent lamp.
Background technology
Existing fluorescent tube great majority are 360 ° of emission of lights, as strengthened the illumination of effective area, fluorescent tube must be arranged in the light fixture with good reflection effect.CN 2186442Y discloses a kind of fluorescent tube, it has a mercury coating with certain width on fluorescent tube outside, and on mercury coating, cover one deck sealing wax, this mercury coating is equivalent to a concave mirror, luminescence center is just in the focus of this concave mirror, mercury reflecting surface to pipe internal reflection, has strengthened Effective Illuminance by light, reaches energy-conservation object.Yet, no matter be by lamp reflector or utilize tube outer wall reflecting surface to carry out reverberation, all can only reflecting part light splitting, as visible ray, and the reflection of light that can not to realize wavelength be 253.7nm, therefore its reflecting effect is not satisfactory, and the enhancing of Effective Illuminance is also very limited, and energy-conserving action is not obvious.CN2580598Y discloses a kind of power saving fluorescent lamps, it is, on the glass-tube of the fluorescent tube inwall corresponding by central angle alpha, special coating is set, described special coating has good reflex to light, particularly can reflection wavelength the light that is 253.7nm, can improve luminous intensity, increase Effective Illuminance, energy-conservationly reach 30%.Yet experience is told us, such result is far from meeting.In electric light source research is manufactured, the energy-saving and cost-reducing eternal target that must become pursuit of product.
Summary of the invention
The object of this invention is to provide a kind of internal reflection energy-saving fluorescent lamp, its light reflecting effect is better, and energy-saving effect is better.
Technical scheme of the present invention 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 glass-tube, it is characterized in that: described glass-tube inwall is provided with reflector and fluorescent coating successively.
As a kind of preferably, described reflector is arranged at glass-tube by 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 °.
First the present invention is coated with reflection powder on the glass-tube inwall corresponding by central angle alpha, and reflector is set, then on reflector and glass-tube, is not coated with reflection powder place and is coated with layer of fluorescent powder in whole glass-tube, and fluorescent coating is set.The light that it can reflection wavelength is 253.7nm, its principle is: the fluorescent material of the ultraviolet ray excited whole glass-tube inwall of the 253.7nm of incident, then the visible ray that fluorescent material is produced intensively irradiates out to that side of not establishing reflector by the reflector of glass-tube one side.Coating structure of the present invention is adapted to various low-pressure gaseous discharge lamp pipes.
In the present invention, titanium dioxide can be selected in described reflector.
The present invention is that glass-tube inwall is provided with reflector and fluorescent coating successively, after first painting reflection powder, is coated with fluorescent material.The good reflection that it has been realized light, the reflection of light that to comprise wavelength be 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 to the fluorescent tube that fluorescent coating arranges reflector being more first set at glass-tube inwall, energy-saving effect reaches more than 15%.
