Description
Technical field
The utility model relates to straight tube fluorescent lamp, relates in particular to the LED straight tube fluorescent lamp.
Background technology
Along with improving constantly of LED lighting engineering and production technology; The field of employment of LED is more and more wideer; Extend to reading lighting and common normal lighting field from original home decoration illumination; Since the advantage that the LED light fixture has energy-saving and environmental protection, long service life etc. to generally acknowledge, alternative traditional fluorescent lamp, Metal halogen lamp and conventional electricity-saving lamp.Conventional straight tube fluorescent lamp two ends all are provided with the civil power electrode, and straight tube fluorescent lamp leans between electrode that electric ballast and starter make lamp tube ends and the mercury grain and produces high-speed electron flow, relies on the fluorescent coating of high-speed electron flow activation tube inner wall luminous; All there are electrode and filament in this conventional fluorescent lamps two ends; Starting current is bigger, and voltage is very high, and filament is short service life; The light decay of fluorescent coating is than very fast; The bulk life time of fluorescent lamp has only 6~12 months usually, and when fluorescent lamp was scrapped, the mercury grain in it then polluted the environment.
The utility model content:
The purpose of the utility model provides a kind of single-ended direct current input LED straight tube fluorescent lamp, and the blue-violet light that its utilizes the LED luminescent device that can send royal purple light to send activates fluoresent coating on the tube inner wall, makes fluoresent coating luminous; Thereby make fluorescent tube continue luminous lighting, this fluorescent tube neither need use the mercury grain, need not in the fluorescent tube to vacuumize; And starting current is little, and voltage is steady, and fluoresent coating only receives the irradiation of royal purple light on the tube inner wall; Can not receive the impact of high voltage, big electric current, light decay is slow, and the bulk life time of fluorescent lamp reaches 6~10 years; When fluorescent lamp is scrapped, do not pollute the environment.
The technical scheme that the utility model is taked is:
A kind of single-ended direct current input LED straight tube fluorescent lamp; It is characterized in that: comprise LED photophore and fluorescent tube; Said fluorescent tube one end opening, other end sealing, the LED photophore is installed in the openend of fluorescent tube; Inwall at fluorescent tube scribbles fluorescent coating, and the peak wavelength of the spectrum of said LED light that photophore sends is 320nm~480nm.
Further, said LED photophore is that direct current is imported, and it comprises lamp socket, electrode, radiator, circuit board and LED lamp pearl; Wherein, the peak wavelength of the spectrum of LED lamp light that pearl sends is 320nm~480nm, passes lamp socket electrode insulation and is electrically connected with LED lamp pearl; All LED lamp pearls are installed on the front of circuit board, and are connected as a single entity through circuit preset on the circuit board, and radiator is fitted on the back side of circuit board; Radiator is installed in the lamp socket, and closely contacts with lamp socket.
Further, radiator and lamp socket are connected as a single entity.
Further, between back of circuit board and radiator, be provided with heat conductive silica gel, circuit board is fixedly connected with radiator.
Further, the openend of fluorescent tube is inserted in the connection endoporus of lamp socket.
Further, the openend at fluorescent tube is provided with tack coat with being connected of lamp socket between the endoporus.
Further, the material of radiator and lamp socket is red copper, copper alloy, aluminum or aluminum alloy.
Owing to the LED photophore that can send royal purple light has been installed at the openend of fluorescent tube; On the inwall of fluorescent tube, be provided with fluorescent coating; After royal purple illumination that the LED photophore sends is mapped to the fluorescent coating on the tube inner wall, just can the activated phosphor coating make it to continue luminous.Because the principle of luminosity of the utility model is different with the principle of luminosity of fluorescent lamp in the prior art; It is that the fluorescent coating that relies on the LED photophore to send on the royal purple illumination shot-light inside pipe wall comes luminogen; In activating luminescence process, do not have the impact of high-speed electron flow, so the light decay speed of fluorescent coating is very slow, simultaneously to fluorescent coating; The inner chamber of fluorescent tube also need not vacuumize; Both the split package assembly can be adopted between fluorescent tube and the LED photophore, after the arbitrary damage in fluorescent tube and the LED photophore, the substitute mode place under repair can be passed through.Also can adopt fixed connection structure between fluorescent tube and the LED photophore, increase user's selectivity, the undulating value of LED photophore voltage and current in the open and close process is less simultaneously, and is suitable when opening with closure with common incandescent lamp bulb.The effect of external ballast also is to convert electric main to direct current, for LED lamp pearl provides direct current.In the utility model, both used less than the mercury grain that pollutes the environment, fluorescent tube does not vacuumize again, and it had both had the energy-saving and environmental protection of LED light fixture, the advantage of long service life; It is big to have the fluorescent light flux again, and the characteristics that the unit power lumen is high are through testing oneself; The amount of lumens that the utility model is every watt is at 80~115 lumens; And the amount of lumens of every watt of conventional fluorescent lamps is about 60 lumens, and the brightness that the utility model is 14 watts is equivalent to 36 watts conventional fluorescent lamps, and energy-saving efficiency reaches 50%~60%; Can reach 6~80,000 hours service life, not only energy-conservation but also environmental protection.
