Description

A kind of long-range T8-LED lamp

Technical field

The utility model relates to a kind of fluorescent tube, relates in particular to a kind of long-range T8-LED lamp.

Background technology

T8 fluorescent tube is a kind of of fluorescent lamp (or claiming fluorescent lamp, light pipe, fluorescent tube), use electric power to activate mercury vapor in argon or neon, form plasma and send short wave ultraviolet, make phosphorus matter send visible fluorescence with illumination, general fluorescent tube is with glass manufacture, socket is housed to connect power supply and the fixing position of fluorescent tube at two ends, different from bulb, fluorescent tube must be provided with ballast, coordinates produce the instantaneous pressure that allows gas that ionization occurs with starter.Common T8 fluorescent tube service life is short, power consumption is large, and luminous transient voltage is very high, has potential safety hazard, and therefore T8-LED fluorescent tube has energy-saving and environmental protection, long service life, use safety lamp plurality of advantages now, has progressively replaced traditional T8 fluorescent tube.Existing T8-LED light source adopts many permutation and combination list LEDs through processing welding in the circuit board, then wiring board and heat-dissipating casing are fixed, and luminous towards one side, lighting angle is too little like this, and another single lamp pearl spaced apart, makes light inhomogeneous.

Chinese patent Granted publication number: CN202403033U, August 29 2012 Granted publication day, a kind of T8-LED fluorescent tube is disclosed, this T8-LED fluorescent tube comprises interconnective aluminium die casting heat-dissipating casing and PC cloudy surface light diffusion cover body, the cross section of aluminium die casting heat-dissipating casing is flat, the cross section of PC cloudy surface light diffusion cover body is oblate arc, and PC cloudy surface light diffusion shell body is positioned at the below of aluminium die casting heat-dissipating casing; On the downside of aluminium die casting heat-dissipating casing, be screwed pcb board, pcb board is between aluminium die casting heat-dissipating casing and PC cloudy surface light diffusion cover body; This T8-LED fluorescent tube also comprises the flattening lamp holder that is connected to aluminium die casting heat-dissipating casing two ends, and the outer face of flattening lamp holder is provided with two lamp bases.Its weak point is that this kind of T8-LED lamp luminescence angle is little, and the light sending is inhomogeneous.

Utility model content

The utility model is little in order to overcome the lighting angle of T8-LED fluorescent tube of the prior art, and the inhomogeneous deficiency of light, provides a kind of lighting angle large, the uniform long-range T8-LED lamp of light.

To achieve these goals, the utility model adopts following technical scheme:

A kind of long-range T8-LED lamp, comprise cylindrical printing opacity fluorescent tube, one side of described printing opacity fluorescent tube is provided with the groove distributing vertically, in described groove, be provided with light source connecting plate, described light source connecting plate inner side is connected in parallel to some LED chips, the bottom of described groove is provided with lamp pearl and dodges groove, described lamp pearl is dodged and in groove, is provided with fluorescence baffle plate, the opening part of described groove is provided with sealing blend stop, the two ends of described printing opacity fluorescent tube are provided with connector, and described light source connecting plate is electrically connected to connector.Connector is connected with external circuitry after energising, LED chip sends blue light, fluorescence baffle plate is provided with phosphor powder layer, and phosphor powder layer is by the blue-light excited rear Yellow light-emitting low temperature of small part, and gold-tinted is combined with remaining blue light and is generated white light, because the phosphor powder layer on fluorescence baffle plate is very even, therefore the white light that finally irradiates out from printing opacity fluorescent tube is very even, and whole printing opacity fluorescent tube is except the dorsal part of light source connecting plate, and remaining place has uniform light to penetrate, lighting angle is large, good illumination effect.

As preferably, the cross section of described fluorescence baffle plate is C font.The inside and outside side of fluorescence baffle plate is all arc surface, thereby keeps whole fluorescence baffle plate glazed thread continuously, evenly, and unchanged, the white light finally irradiating is more even.

As preferably, in described connector, be also provided with LED driver, described LED driver is electrically connected to light source connecting plate.LED driver is used for regulating electric current, voltage, thereby keep the voltage entering in LED chip to be positioned at the range of nominal tension, current stabilization, thereby the luminosity of maintenance LED chip the best, the two ends connector of printing opacity fluorescent tube directly can access in external circuitry, uses safer.

As preferably, fluorescence baffle plate is greater than 2/3 to the ultimate range between printing opacity fluorescent tube sidewall and the diameter ratio of printing opacity fluorescent tube.In order to increase as much as possible light irradiating angle, therefore the position of fluorescence baffle plate as much as possible away from the light ejecting end of printing opacity fluorescent tube, the scope of dwindling light source connecting plate dorsal part, thereby increase irradiating angle, range of exposures.

Therefore, the utlity model has lighting angle large, the uniform beneficial effect of light.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is further described:

A kind of long-range T8-LED lamp as depicted in figs. 1 and 2, comprise cylindrical printing opacity fluorescent tube 1, printing opacity fluorescent tube is made by glass or plastics, printing opacity light in the present embodiment is made by glass, one side of printing opacity fluorescent tube 1 is provided with the groove 2 distributing vertically, in described groove 2, be provided with light source connecting plate 3, light source connecting plate is provided with two parallel metal circuit boards, as shown in Figure 3, article two, on parallel metal circuit board, be connected in parallel to some LED chips 4, the bottom of groove 2 is provided with lamp pearl and dodges groove 5, LED chip stretches into lamp pearl and dodges in groove, lamp pearl is dodged and in groove 5, is provided with fluorescence baffle plate 6, the cross section of fluorescence baffle plate 6 is C font, the inner that fluorescence baffle plate is dodged groove from lamp pearl is stretched in printing opacity fluorescent tube, the opening part of groove 2 is provided with sealing blend stop 7, the two ends of printing opacity fluorescent tube 1 are provided with connector 8, light source connecting plate 3 is electrically connected to connector 8, in connector 8, be also provided with LED driver 9, LED driver 9 is electrically connected to light source connecting plate 3.After connector is connected with external circuitry power supply, LED chip sends blue light, fluorescence coating on fluorescence baffle plate produces gold-tinted after exciting under the irradiation of part blue light, gold-tinted is combined rear generation white light with remaining blue light, last white light irradiates out from the tube wall of printing opacity fluorescent tube, and white light is long-range light, can be irradiated to far distance, because the phosphor powder layer on fluorescence baffle plate is very even, so white light evenly continuously, evenly; In the present embodiment, fluorescence baffle plate 6 is 5/6 to the diameter ratio of the ultimate range between printing opacity fluorescent tube 1 sidewall and printing opacity fluorescent tube 1, in order to increase as much as possible light irradiating angle, therefore the position of fluorescence baffle plate as much as possible away from the light ejecting end of printing opacity fluorescent tube, dwindle the scope of light source connecting plate dorsal part, thereby increase irradiating angle, range of exposures.Therefore, the utlity model has lighting angle large, the uniform beneficial effect of light.
