Abstract

The utility model relates to the technical field of light-emitting diode (LED) lighting, in particular to a novel LED fluorescent lamp. The novel LED fluorescent lamp comprises a lamp tube, an aluminum member, a lamp plate, and an LED lamp bead. The aluminum member is arranged along the length direction of the inner portion of the lamp tube. The LED lamp bead is connected with the lamp plate in a key mode. The cross section of the aluminum member is in an arc shape. A groove is formed in the middle of the upper surface of the aluminum member. Wiring grooves are formed at two sides of the lower surface of the aluminum member. The lamp plate is arranged in the groove of the aluminum member. The novel LED fluorescent lamp further comprises a packaging glue layer which is covered on the lamp plate and the LED lamp bead and is packaged inside the groove of the aluminum member. According to the novel LED fluorescent lamp, light rays are diffused through a high-reflective film, the aluminum member, the packaging glue layer and the lamp tube, meanwhile, a red LED supply light source is arranged in a stage mode, the light rays are enabled to be soft, and a color rendering index is increased. In addition, the lamp tube is used for insulation, full contact between the lamp plate and the aluminum member enables heat radiating performance to be stronger, the aluminum member is attached to the surface of the lamp tube, the distance between the LED lamp bead and a light permeable face of the lamp tube is enlarged, and the problems of faculae and shadows are avoided.

Description

A kind of Novel LED fluorescent lamp

Technical field

The utility model relates to the LED lighting technical field, especially a kind of Novel LED fluorescent lamp.

Background technology

Along with the development of semiconductor technology, the LED industry has obtained progress at full speed, as a kind of green energy resource, has been widely used in people's the work and life.Traditional LED fluorescent lamp consists of fluorescent tube by semicircle metal shell and semicircle Transparent lamp shade, in fluorescent tube, establish circuit board, distribute and be arranged on light that the LED lamp pearl on the circuit board the sends Transparent lamp shade by semicircle, thereby obtain evenly soft light, to satisfy people's needs.There are the problems such as the diffusion angle of light is little, light efficiency is not good enough, printing opacity is inhomogeneous in this LED fluorescent lamp; Simultaneously, traditional LED fluorescent lamp often needs to guarantee to greatest extent the insulating properties of fluorescent tube and the thermal diffusivity that affected fluorescent tube integral body, has had a strong impact on the service life of LED fluorescent lamp.

The utility model content

The purpose of this utility model provide a kind of simple in structure, colour rendering good, the Novel LED fluorescent lamp of luminous and good heat dissipation effect, is intended to solve the problems of the prior art.

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

A kind of Novel LED fluorescent lamp, it comprises fluorescent tube, al member, lamp plate and LED lamp pearl, described al member is arranged along the length direction of fluorescent tube inside, described LED lamp pearl is connected on the lamp plate, the cross section of described al member is curved, and the both sides that the middle part of its upper surface offers groove, lower surface offer the wire arrangements groove; Described lamp plate is arranged in the groove of al member;

This Novel LED fluorescent lamp also comprises:

The encapsulation glue-line, described encapsulation glue-line covers lamp plate and LED lamp pearl and be encapsulated in the groove of al member.

Preferably, described LED lamp pearl comprises the additional light source of red LED and common LED lamp pearl, and described red LED is replenished being arranged between the common LED lamp pearl of light source stage.

Preferably, also be provided with the highly reflecting films of offering porose position between described lamp plate and the encapsulation glue-line, described LED lamp pearl is connected on the lamp plate by the position, hole on the highly reflecting films.

Preferably, described fluorescent tube is glass tube or PC pipe.

Owing to adopted such scheme, LED lamp pearl of the present utility model carries out the diffusion of light by highly reflecting films, al member, encapsulation glue-line and fluorescent tube itself, luminous evenly, light efficiency is high; Simultaneously, the red LED that arranges by interim interval is replenished light source so that light is softer, colour rendering index further improves; In addition, because lamp body itself is to insulate by fluorescent tube, fully contacting also so that the thermal diffusivity of lamp body is stronger of lamp plate and al member prolonged service life; And the surface that the al member of arc section is pressed close to fluorescent tube is arranged, avoided occurring near fluorescent tube because of LED lamp pearl the problem of hot spot so that kept larger distance between LED lamp pearl and the fluorescent tube, the wire arrangements groove of al member lower surface setting has very strong practicality so that more conveniently when lamp body is assembled carry out line arrangement and installation and lamp body assembling.

Description of drawings

Fig. 2 is the lamp plate plan structure schematic diagram of the utility model embodiment.

Among the figure: 1, fluorescent tube; 2, al member; 21, wire arrangements groove; 3, lamp plate; 4, highly reflecting films; 5, LED lamp pearl; 51, red LED is replenished light source; 52, common LED lamp pearl; 6, encapsulation glue-line.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.

As illustrated in fig. 1 and 2, a kind of Novel LED fluorescent lamp that the utility model provides, it comprises fluorescent tube 1, al member 2, lamp plate 3 and LED lamp pearl 5; Wherein: fluorescent tube 1 is glass tube or PC pipe, and the effect of both having played the lamp body insulation also helps dispersing of light;

Al member 2 is as the bearing structure of lamp plate 3 time, also play the effect that strengthens lamp body thermal diffusivity and auxiliary divergence of beam, its length direction along fluorescent tube 1 inside is arranged, the cross section is curved, and the both sides that the middle part of its upper surface offers groove, lower surface offer wire arrangements groove 21.

LED lamp pearl 5 is connected on the lamp plate 3, covers and is encapsulated in the groove of al member 2 by encapsulation glue-line 6; Simultaneously, can offer porose highly reflecting films 4 in the upper surface setting of lamp plate 3 according to use, the Production requirement of reality, LED lamp pearl 5 is connected on the lamp plate 3 by the position, hole on the highly reflecting films 4, further improves the light efficiency of lamp with this.

Simultaneously, LED lamp pearl 5 comprises the additional light source 51 of red LED and common LED lamp pearl 52, and red LED is replenished being arranged between the common LED lamp pearl 52 of light source 51 stages, so that luminous softer, the raising colour rendering index of lamp body.

Because encapsulation glue-line 6 covers on the LED lamp pearl 5, realize breaing up, make lamp body luminous evenly light, improve luminous efficiency; Al member 2 adopts the arcuate structure body, it presses close to the sub-fraction of the inner surface of fluorescent tube 1, thereby so that kept larger distance to avoid because LED lamp pearl 5 problem of hot spot occurs near fluorescent tubes 1 between LED lamp pearl 5 and the fluorescent tube 1, the wire arrangements groove 21 of the lower surface setting of al member 2 so that when lamp body assemble more convenient carry out line arrangement and installation and lamp body assemble; In addition, the close contact of al member 2 and lamp plate 3 also helps the heat radiation of lamp body, and the edge of the groove of al member 2 does not have corner angle, and round and smooth being transitioned on the al member 2 of foot also helps dispersing of light, has very strong practicality.

The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
