Abstract

The utility model discloses an improved structure of an LED daylight lamp, comprising a lampshade, a light source module, a radiating lamp housing, a driving power supply and lamp cap seats, wherein the light source module is arranged on the outer wall of the radiating lamp housing; the lampshade is covered on the surface of the light source module; and the two lamp cap seats are respectively arranged at the two ends of the radiating lamp housing. The driving power supply consists of a rectifying filter module and a constant-current module which are electrically connected with each other and respectively taken as an independent part to be arranged at the two ends of the radiating lamp housing; the rectifying filter module is internally connected with one end of the light source module, and the constant-current module is internally connected with the other end of the light source module. In the utility model, the rectifying filter module and the constant-current module are respectively designed into one independent part to be electrically connected with the two ends of the radiating lamp housing, thus ensuring the basically consistent distance of a current circuit, and leading to uniform diversion of the whole light source module and more uniform brightness of the LED lamp in the light source module.

Description

The improvement structure of LED fluorescent lamp

Technical field

The utility model relates to a kind of light fixture, particularly relates to a kind of improvement structure of LED fluorescent lamp.

Background technology

At present, the LED fluorescent lamp energy-conservation owing to it, efficiently be widely used.The LED fluorescent lamp of commonly using (as shown in Figure 1 and Figure 2) comprises lampshade 1 ', light source module 2 ', heat-dissipation lamp housing 3 ', driving power 4 ', bulb socket 5 '.The driving power 4 ' of this LED of commonly using fluorescent lamp has only one, usually be installed in an end of heat-dissipation lamp housing 3, be electrically connected with an end of light source module 2 ', this structural design, when electric current when the A of light source module 2 ' holds the B end, middlely have long distance, can produce certain pressure drop, make that two ends (side a and b) electric current of light source module 2 ' can be inconsistent, cause the inequality of brightness.

The utility model content

The purpose of this utility model is to provide a kind of improvement structure of even brightness LED fluorescent lamp.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of improvement structure of LED fluorescent lamp; It comprises lampshade, light source module, heat-dissipation lamp housing, driving power, bulb socket; Described light source module is installed on the heat-dissipation lamp housing outer wall, and lampshade covers light source module surface and is fixed on the heat-dissipation lamp housing; Described two bulb sockets are installed in the heat-dissipation lamp housing two ends respectively, and driving power is installed on the heat-dissipation lamp housing; Described driving power is made of rectification filtering module and constant flow module, and rectification filtering module is electrically connected with constant flow module; Described rectification filtering module and constant flow module are installed in the two ends of heat-dissipation lamp housing respectively as parts independently; Described rectification filtering module external power supply, in be connected to an end of light source module, the external rectification filtering module of described constant flow module, in connect the other end of light source module.

Described constant flow module has a plurality of.

After adopting such scheme, because rectification filtering module and constant flow module in the utility model driving power are designed to two independently parts, be installed in the two ends of heat-dissipation lamp housing respectively and be electrically connected with the two ends of light source module respectively, so just can guarantee this current loop apart from basically identical, the voltage that is assigned on each LED lamp is average relatively, closely, LED modulating voltage at a distance differs less, the water conservancy diversion of whole light source module is average, this makes that the LED lamp brightness in the light source module is comparatively even.

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

Fig. 2 is a structural representation of commonly using the LED fluorescent lamp;

Fig. 3 is a three-dimensional exploded view of the present utility model;

Fig. 4 is a structural representation of the present utility model;

Fig. 5 is a circuit block diagram of the present utility model.

The specific embodiment

As shown in Figure 3, the utility model is a kind of improvement structure of LED fluorescent lamp; It comprises lampshade 1, light source module 2, heat-dissipation lamp housing 3, driving power 4, bulb socket 5.

Described light source module 2 is installed on heat-dissipation lamp housing 3 outer walls, and lampshade 1 covers light source module 2 surfaces and is fixed on the heat-dissipation lamp housing 3; Described two bulb sockets 5 are installed in heat-dissipation lamp housing 3 two ends respectively.

As Fig. 4, shown in Figure 5, described driving power 4 is made of rectification filtering module 41 and constant flow module 42.Described rectification filtering module 41 and constant flow module 42 are installed in the two ends (with reference to shown in Figure 3) of heat-dissipation lamp housing 3 respectively as parts independently.The input external power supply of rectification filtering module 41, its output connect the input of constant flow module 42 and the A end of light source module 2 respectively.The output of constant flow module 42 connects the B end of light source module 2.

Constant flow module 42 can be a plurality of, and this depends on the length of LED fluorescent tube, if the length of LED fluorescent tube is longer, then driving power 4 can be made of a rectification filtering module 41 and two constant flow modules 42.

Emphasis of the present utility model just is: described rectification filtering module and constant flow module are electrically connected the two ends of light source module respectively as parts independently.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
