Abstract
The utility model discloses a light-emitting diode (LED) lamp tube, which comprises a metal framework, a substrate, a diffuser, LED light sources and a plug, wherein the outer side of the metal framework is provided with diffuser troughs; the diffuser is provided with fasteners which correspond to the diffuser troughs; the metal framework is provided with a platform; the platform is provided with the substrate; the substrate is provided with the LED sources; inclined planes are formed at both sides of the substrate on the metal framework; reflective sheeting is pasted to each inclined plane; and the outer surface of the metal framework is provided with bulges. The surface area is increased by arranging the bulges on the metal framework, so that the metal framework can also be used as a radiator, and the service life of the LED light sources is prolonged. The inclined planes are formed at both sides of the substrate on the metal framework, and the reflective sheeting is pasted to each inclined plane, so that the light reflection is increased, the light loss is reduced, the light efficiency is increased, the light uniformity is increased, and obvious light spots are eliminated.
Description
Technical field
The utility model relates to a kind of light fixture, relates in particular to a kind of LED fluorescent tube.
Background technology
The LED fluorescent tube is to adopt a kind of fluorescent tube of LED as illuminator.Traditional fluorescent lamp contains the heavy metal pollution material; Make the fluorescent tube scrap to the pollution of environment very serious and, and the LED light pipe adopts light emitting diode as light source, the fluorescent tube heating less, noiseless, protection eyes, operating voltage range is wide, versatility good, coloury advantage; Light efficiency is higher, more energy-conservation, longer service life; And more environmental protection, generally be used for general lighting, room lightings such as office building, market, restaurant, school, family, factory.Become the ideal product that the current stage replaces fluorescent tube.What place the paster light source in the present LED fluorescent tube is a plane, and some light of energising back is absorbed by metal shell or substrate, causes the light waste.The planar light part can not directly reflex on the diffuser, and needs repeatedly reflection, wherein consume the part light energy, so light extraction efficiency can be lower.The lamp luminescence brightness irregularities can obviously be seen hot spot.Even use milky white light transmissive material also must use external power supply or special-shaped fluorescent tube can make bright dipping even.
The utility model content
The purpose of the utility model is to provide a kind of LED fluorescent tube, to solve the problem that luminous energy is wasted, light extraction efficiency is low, the lamp luminescence brightness irregularities can obviously be seen hot spot.
The purpose of the utility model is to realize through following technical scheme:
A kind of LED fluorescent tube comprises metal framework, substrate, diffuser, led light source, reaches plug, and said metal frame arranged outside has the diffuser draw-in groove, and said diffuser is provided with and the corresponding buckle of said diffuser draw-in groove; Have platform on the said metal framework, on the said platform substrate is installed, on the said substrate led light source is installed; The metal framework of said substrate both sides is the inclined plane; Be pasted with reflective sheeting on the said inclined plane.
Said inclined plane is a kind of in " V " font or " eight " font.
Said metal framework outer surface is provided with convexity.
The beneficial effect of the utility model is: metal framework is provided with convexity has increased surface area, and metal framework can be used as radiator simultaneously, has prolonged the life-span of led light source.The metal framework of substrate both sides is the inclined-plane, is pasted with reflective sheeting on the inclined-plane, increases reflection of light and the loss that reduces light, improves light efficiency, increases the uniformity of light, eliminates obvious hot spot problem.

According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the described LED fluorescent tube of a utility model three-dimensional exploded view.
Fig. 2 is that the described inclined-plane of the utility model becomes " V " font LED fluorescent tube sectional view.
Fig. 3 is that the described inclined-plane of the utility model becomes " eight " font LED fluorescent tube sectional view.
1, metal framework; 2, substrate; 3, reflective sheeting; 4, diffuser; 5, plug; 6, led light source; 7, convexity; 8, diffuser draw-in groove; 9, bayonet socket; 10, platform.
The specific embodiment
In Fig. 1～3 illustrated embodiments; Described, a kind of LED fluorescent tube of the utility model; Comprise metal framework 1, substrate 2, diffuser 4, led light source 6, reach plug 5; Said metal framework 1 arranged outside has diffuser draw-in groove 8, and said diffuser 4 is provided with and said diffuser draw-in groove 8 corresponding buckles 9; Have platform 10 on the said metal framework 1, on the said platform 10 substrate 2 is installed, on the said substrate 2 led light source 6 is installed; The metal framework 1 of said substrate 2 both sides is the inclined plane; Different according to needed ejaculation light opening angle, said inclined plane is set to " V " font or " eight " font; Be pasted with reflective sheeting 3 on the said inclined plane; Said metal framework 1 outer surface is provided with protruding 7.
Led light source 6 luminous back irradiate light directly reflex to light on the diffuser 4 through reflective sheeting 3 to the reflective sheeting 3 that sticks on the inclined plane, have reduced energy consumption, have improved light extraction efficiency.Metal framework 1 is provided with convexity 7, and the surface area that has increased considerably metal framework 1 has improved its heat dispersion.
Claims (3)
1. a LED fluorescent tube comprises metal framework, substrate, diffuser, led light source, reaches plug, and said metal frame arranged outside has the diffuser draw-in groove, and said diffuser is provided with and the corresponding buckle of said diffuser draw-in groove; Have platform on the said metal framework, on the said platform substrate is installed, on the said substrate led light source is installed; It is characterized in that: the metal framework of said substrate both sides is the inclined plane; Be pasted with reflective sheeting on the said inclined plane.
