Abstract

The utility model discloses a waterproof ventilating structure of an LED lamp, comprising an LED lamp housing and fixed supports respectively connected at the two ends of the lamp housing, the waterproof ventilating structure is characterized in that the LED lamp housing comprises two end covers, two pipe heads, and a PC pipe; two pipe heads are connected to the two ends of the PC pipe, an L-shaped sealing ring is disposed between the PC pipe and the pipe head; the pipe heads and the end covers are connected via a cross recessed pan head self tapping screw, a waterproof ventilating film is disposed between the pipe heads and the end covers. The waterproof ventilating structure of an LED lamp in the utility model, compared with the prior art, is advantaged by providing waterproof ventilating effect for LED lamp, balancing internal and external lair pressures of LED lamp, and becoming more beneficial to heat radiation.

Description

The waterproof and breathable structure of LED lamp

Technical field

The utility model belongs to lighting technical field, especially relates to a kind of waterproof and breathable structure of LED lamp.

Background technology

As everyone knows, because the LED light fixture has luminous efficiency height, long service life, not fragile, advantage such as power consumption is few, environmental protection and volume are little, the LED lamp has been most important a kind of light emitting source in recent years.Early stage because luminosity deficiency usually is used in indicator lamp and display board luminous, but in recent years because the breakthrough of material and technology, and the lifting more than the brightness of LED lamp has had very makes the present conventional illumination device of LED lamp replacement gradually.Yet currently marketed LED lamp does not have the waterproof and breathable effect or the waterproof and breathable effect is very little, therefore is necessary to be improved.

The utility model content

The purpose of this utility model is to provide a kind of LED light fixture that can make that the waterproof and breathable effect is arranged in order to solve above-mentioned the deficiencies in the prior art, can balance LED lamp inner and outer air pressure, more help the waterproof and breathable structure of the LED lamp that dispels the heat.

To achieve these goals, the waterproof and breathable structure of a kind of LED lamp that the utility model is designed comprises the LED lamp housing and is connected the fixed support at lamp housing two ends, it is characterized in that described LED lamp housing is made of two end caps, two tube heads and PC pipe; PC pipe two ends are connected with two tube heads, are provided with the L RunddichtringO between the PC tube and tube head; Tube head is connected by cross recess coiled hair self-tapping screw with end cap, is provided with waterproof ventilated membrane between tube head and the end cap.Described PC pipe inside is provided with aluminium section bar, and aluminium section bar simultaneously is covered with the LED substrate, is provided with the current-limiting circuit plate between aluminium section bar and the LED substrate, and the another side of aluminium section bar is connected with current-limiting circuit plate plastic casing.Being provided with water joint, on water joint, be provided with the waterproof DC plug near on the tube head of current-limiting circuit plate plastic casing.

The waterproof and breathable structure of the LED lamp that the utility model obtains is compared the advantage that is had with prior art and is: make the LED light fixture that the waterproof and breathable effect be arranged, can balance LED lamp inner and outer air pressure, and more help heat radiation.

Fig. 1 is an overall structure schematic diagram of the present utility model.

Among the figure: waterproof ventilated membrane 1, tube head 2, current-limiting circuit plate plastic casing 3, current-limiting circuit plate 4, aluminium section bar 5, LED substrate 6, decoration plug 7, cross recess coiled hair self-tapping screw 8, little gasket seal 9, end cap 10, big gasket seal 11, water joint 12, waterproof DC plug 13, PC pipe 14, L RunddichtringO 15, fixed support 16.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Embodiment:

As shown in Figure 1, the waterproof and breathable structure of a kind of LED lamp that present embodiment provides comprises the LED lamp housing and is connected the fixed support 16 at lamp housing two ends, and described LED lamp housing is made of two end caps 10, two tube heads 2 and PC pipe 14; Be provided with L RunddichtringO 15 between PC pipe 14 and the tube head 2; Tube head 2 is connected by cross recess coiled hair self-tapping screw 8 with end cap 10, is furnished with little gasket seal 9 on the cross recess coiled hair self-tapping screw 8, and cross recess coiled hair self-tapping screw 8 outer being with are decorated plug 7, make the LED lamp more attractive in appearance; Post waterproof ventilated membrane 1 between tube head 2 and the end cap 10, waterproof ventilated membrane 1 has very strong water repellency, but can make air be easy to penetrate waterproof ventilated membrane 1, make the LED light fixture that the waterproof and breathable effect be arranged, can balance LED lamp inner and outer air pressure, more help heat radiation, be lined with big gasket seal 11 between waterproof ventilated membrane 1 and the end cap 10.PC manages 14 inside and is provided with aluminium section bar 5, and aluminium section bar 5 one sides are covered with LED substrate 6, are provided with current-limiting circuit plate 4 between aluminium section bar 5 and the LED substrate 6, and the another side of aluminium section bar 5 is connected with current-limiting circuit plate plastic casing 3.Being provided with water joint 12, on water joint 12, be provided with waterproof DC plug 13 near on the tube head 2 of current-limiting circuit plate plastic casing 3.At this, the PC pipe can adopt double-colored PC pipe.
