Abstract

The utility model discloses an LED (light-emitting diode) daylight lamp, and relates to the field of LED lamps. The LED daylight lamp comprises a lamp tube body, plugs and a metal base PCB (printed circuit board), the plugs are connected with two ends of the lamp tube body, the metal base PCB is arranged in the lamp tube body, a limit clamping strip is arranged in each plug, circular holes and screws are formed in two ends of the metal base PCB inserted into the plugs, and the screws penetrate the circular holes and are used for fixing the metal base PCB. By the aid of the positioning screws, the plugs can be fixed onto an LED daylight lamp tube, the metal base PCB can be fixed into the LED daylight lamp tube, and the structure of the LED daylight lamp is simplified. The positioning screws are made of plastic materials, and a metal portion outside the lamp tube body is omitted, so that the safety problem is solved. As the metal base PCB is fixed in a stretching mode, the problem of bending of the lamp tube after heating can be solved.

Description

A kind of LED fluorescent lamp

Technical field

The utility model relates to the LED field of light fittings, relates in particular to a kind of LED fluorescent lamp.

Background technology

Power supply plug and the fixed form between lamp tube body of existing LED fluorescent lamp probably have viscose glue, buckle, metal screw and snap ring, but the shortcoming of these several fixed forms:

1, viscose glue fixed form, there is the excessive glue cleaning in some glue, assembling and some glue process in this fixed form, and consuming time more, production efficiency lowly reaches the problems such as inconvenient maintenance;

2, buckle fixed form, this fixed form is punching on the aluminium alloy of fluorescent tube, utilize the strain of the one or more buckles on the plastic cement plug to be inserted in hole, but the insufficient strength that this mode is fixing, the body of plug is longer, the actual length of illumination of fluorescent tube has shortened, and plug also has swing, can not reach the standard of safety;

3, metal screw fixed form, the shortcoming of this fixed form is that production efficiency is low, have the safety problem, and plastic parts is more;

4, snap ring fixed form, the shortcoming of this fixed form is that structure is very complicated, production efficiency is low.

The utility model content

The utility model is for the shortcoming of fixed form and propose a kind of LED fluorescent lamp between power supply plug and lamp tube body in prior art, fixed form between this daylight lamp power source plug and lamp tube body solves the loosening problem of plug, product meets the safety standard, and the efficiency of production assembling is high.

The technical solution of the utility model is as follows:

A kind of LED fluorescent lamp, comprise lamp tube body and the plug be connected with the lamp tube body two ends, also comprise the Metal Substrate pcb board in lamp tube body, spacing card article is set in plug, the part of Metal Substrate pcb board two ends insertion plug has circular hole and fixes the screw of Metal Substrate pcb board through circular hole.

Above-mentioned Metal Substrate pcb board material is aluminium or copper.

Above-mentioned screw comprises the boss on base, base and invests in the shape of a spiral the fastener of boss side.

Above-mentioned screw is plastic cement material.

The beneficial effects of the utility model are: the LED fluorescent tube only just can synthesize plug by set screw and reach Metal Substrate PCB fixing in fluorescent tube on fluorescent tube, has accomplished simplification on structure; Because the set screw material is plastic rubber material, there is not the metal part in the lamp tube body outside, has therefore solved safety problem; Owing to adopting Metal Substrate PCB stretching fixed form, can solve the buckling phenomenon that fluorescent tube produces afterwards in heating.

The specific embodiment

Now be further described the utility model by reference to the accompanying drawings in order better to illustrate.

As shown in Figures 1 to 8, a kind of LED fluorescent lamp, comprise lamp tube body 1 and the plug 3 be connected with lamp tube body 1 two ends, also comprise the Metal Substrate pcb board 2 in lamp tube body 1, plug 3 is interior arranges spacing card article 4, and the part that plugs 3 are inserted at Metal Substrate pcb board 2 two ends has circular hole 6 and fixes the screw 5 of Metal Substrate pcb board through circular hole; Metal Substrate pcb board 2 materials are aluminium or copper; Screw 5 comprises the boss 13 on base 11, base and invests in the shape of a spiral the fastener 12 of boss side; Screw 5 is plastic cement material.

The assembling of the utility model LED fluorescent lamp: the structure before screw 5 is fixing as shown in Figure 2, screw 5 inserts from plug 3 tappings, through the circular hole 6 in Metal Substrate pcb board 2, utilize the boss 13 of screw 5, the screw 5 at difference rotating metallic base pcb board 2 two ends, Metal Substrate pcb board 2 is stretched to direction of both ends, the stretched lamp tube body 1 that makes of Metal Substrate pcb board 2 is subject to the compression stress to center from end face, under the effect of spacing card article 4, complete Metal Substrate pcb board 2 fixing in lamp tube body 1, the structure after screw 5 is fixing as shown in Figure 3; The dismounting of LED fluorescent lamp, only unclamp the screw 5 at end plug 3 places, the LED fluorescent lamp can be dismantled, thereby make LED fluorescent lamp of the present utility model have easy assembling and easily detachable advantage.
