Abstract

Disclosed is a light-emitting diode (LED) daylight lamp. The LED daylight lamp comprises an aluminum tube, plugs, LED lamp beads, an aluminum substrate, a poly carbonate (PC) cover and a driving power supply. The LED lamp beads are distributed on the aluminum substrate, the driving power supply supplies power to the LED lamp beads, the aluminum substrate is accommodated on the upper surface of the aluminum tube, the PC cover is buckled with the aluminum tube, and two ends of the buckled aluminum tube and PC cover are sealed through the plugs. The aluminum tube comprises a semi-circular cavity used for accommodating the driving power supply, an accommodating part for accommodating the aluminum substrate is formed on the upper surface of the semi-circular cavity, and a pair of inner clamping grooves which are arranged face to face are formed above the accommodating part. The PC cover comprises an arc-shaped light-guiding surface, and a pair of outer clamping hooks which are arranged back to back are formed on the end portions of two sides of the light-guiding surface. The outer clamping hooks are respectively buckled into the inner clamping grooves. After the LED daylight lamp is assembled, the PC cover is located above the LED lamp beads, and therefore a formed illumination angle is large, the light-guiding surface of the whole PC cover can be illuminated, and dark zones do not exist.

Description

The LED fluorescent lamp

[technical field]

The utility model relates to fluorescent lamp, particularly a kind of LED fluorescent lamp.

[background technology]

See also Fig. 1, present common LED fluorescent lamp mainly is comprised of following components: aluminum pipe 10, plug 20, LED light source 30, PC cover 40 and driving power 50.Driving power 50 is arranged in the space of aluminum pipe 10, is LED light source 30 power supplies.LED light source is laid on the upper surface of aluminum pipe 10, and with PC cover 40 and aluminum pipe 10 fastenings, LED light source 30 is covered.The two ends of the aluminum pipe 10 after fastening and PC cover 40 seal and use screw 60 lockings with plug 20.

Please in conjunction with consulting Fig. 2 and Fig. 3, in present LED fluorescent lamp, PC cover 40 is to adopt the mode of outer button with the manner of aluminum pipe 10, namely the buckle at PC cover 40 edges from outside snap in draw-in groove on aluminum pipe 10 (seeing Fig. 3 for details).The structure of this exterior buckle type can cause the LED fluorescent lamp to form the dark space, and its reason is that the grab of aluminum pipe 10 sides blocks the light that LED light source 30 sends, and makes the side be formed with the dark space.In addition, the structure of this exterior buckle type also can cause the situation of uneven illumination, and its reason is LED light source 30 above the fastening part, and distance P C cover is nearer, thereby can see LED light source 30 from outer, makes uneven illumination.

[utility model content]

In view of this, for overcoming the deficiencies in the prior art, the utility model provides a kind of LED fluorescent lamp of no dark space.

A kind of LED fluorescent lamp, comprise aluminum pipe, plug, LED lamp pearl, aluminium base, PC cover and driving power, described LED lamp pearl is distributed on described aluminium base, described driving power is described LED lamp pearl power supply, aluminium base is housed in the upper surface of described aluminum pipe, described PC cover fastens with described aluminum pipe, and the two ends of the described aluminum pipe after fastening and PC cover seal with described plug.Described aluminum pipe comprises the semicircular cavities of accommodating driving power, and the upper surface of described semicircular cavities is formed with the resettlement section of accommodating described aluminium base, and the top of described resettlement section is formed with a pair of inner card cage that arranges in opposite directions.Described PC cover comprises the light guiding surface of arc, and the end of the both sides of described light guiding surface is formed with the outer grab of a pair of opposing setting.Described outer grab fastens to respectively in described inner card cage.

Preferably, be distributed with the two described LED lamp pearls of row on described aluminium base, the whole described light guiding surface of described PC cover all is positioned on the upper surface of described lamp pearl, the center distance W of the two described lamp pearls of row is 7.2 millimeters, and the upper surface of described lamp pearl is 11.6 millimeters to the height H of the inside top of described light guiding surface.

Preferably, the two described lamp pearls of row and the formed maximum lighting angle α of described PC cover reach more than 150 °.

Preferably, be formed with the waveform leaded light striped of continuous distributed on the inner surface of the light guiding surface of described PC cover.

After LED fluorescent lamp assembling of the present utility model was completed, the PC cover was positioned at the top of LED lamp pearl, and formed lighting angle is large, on the light guiding surface 72 of whole PC cover 70, illumination was arranged all, did not have the dark space.

[specific embodiment]

For understanding better the utility model, below with reference to accompanying drawing and instantiation, the utility model is described in detail.

In order to improve the existing weak point of existing LED fluorescent lamp, the utility model improves the aluminum pipe of LED fluorescent lamp and the structure of PC cover.

LED fluorescent lamp of the present utility model equally mainly comprises aluminum pipe, plug, LED light source, PC cover and driving power.Driving power is arranged in the space of aluminum pipe, is the LED light source power supply.LED light source is laid on the upper surface of aluminium base, and with PC cover and aluminum pipe fastening, LED light source is covered.The two ends of the aluminum pipe after fastening and PC cover seal and use screw lock with plug.

The aluminum pipe 60 that the LED fluorescent lamp of preferred embodiment of the present utility model adopts as shown in Figure 4.Aluminum pipe 60 comprises the semicircular cavities 62 of accommodating LED drive circuit.The upper surface of semicircular cavities 62 is formed with the resettlement section 64 of accommodating LED light source aluminium base.The top of resettlement section 64 is formed with a pair of inner card cage 66 that arranges in opposite directions.

The PC cover 70 that the LED fluorescent lamp of preferred embodiment of the present utility model adopts as shown in Figure 5.PC cover 70 forms the light guiding surface 72 of arc, and the end of the both sides of light guiding surface 72 is formed with the outer grab 74 of a pair of opposing setting.The inner surface of light guiding surface 72 is formed with the waveform leaded light striped 76 of continuous distributed.
