Abstract

A waterproof moisture-proof light-emitting diode (LED) landscape lamp comprises a casing, a plug with a water steam exchange channel, a support, a circuit board, LED lamp beads arranged on the circuit board and a transparent lamp shade board. The casing comprises a cavity and a groove. The circuit board is arranged on a base plate of the groove, an LED driving power supply is arranged in the cavity, the plug is detachably connected with two ends of the casing, and the support is detachably connected with the plug. The waterproof moisture-proof LED landscape lamp is characterized by further comprising a plurality of lenses with open inner cavities. The lenses cover the LED lamp beads, and the opening ends of the lenses are bonded to the circuit board. The end face in the length direction of the circuit board is bonded to a wall board of the groove through radiating sealing adhesive which covers the end faces at two ends of the circuit board in the length direction and is bonded to the base plate of the groove. By means of the structure, the welding points of the LED lamp beads and the circuit board and a circuit of the circuit board are separated from the external. The lamp has good radiating performance and prolongs service life.

Description

A kind of waterproof and dampproof LED Landscape Lamp

Technical field

The utility model relates to a kind of lighting equipment, especially a kind of LED Projecting Lamp.

Background technology

In recent years, the construction of city lighting engineering strengthens the image in city as the important measures of improvement and beautifying urban environment; Under the attention of Government and enterprise, the brightening construction has obtained unprecedented development.The light fixture that the tradition lighting engineering uses, as superseded in sodium vapor lamp, Metal halogen lamp etc., replaced by low energy consumption high life, coloury LED Projecting Lamp, but the element of LED Projecting Lamp is extremely sensitive to humidity and steam, so require the IP degree of protection of LED Projecting Lamp more than IP65, the guarantee normal operation.

The structure of existing LED Projecting Lamp employing conventional lamp or improvement form, its LED Projecting Lamp waterproof comprises shell, the plug with the water-vapor exchange passage, support, circuit board, is arranged on LED lamp pearl and clear lamp cover plate on circuit board, described shell comprises a die cavity and type groove, circuit board is arranged on the base plate of type groove, the LED driving power is arranged in die cavity, the two ends of plug and shell removably connect, and support and plug removably connect.Existing problems are: LED Projecting Lamp poor sealing performance, easily entry and cause and be short-circuited and damage; Or have water vapour to enter in the chamber, and circuit board is corroded, and reduction is short service life.

The utility model content

The purpose of this utility model is: a kind of waterproof and dampproof LED Landscape Lamp is provided, and it can prevent effectively that sealing or water vapour enter in lamp body, and waterproof and sealing energy property are good, avoid the circuit of circuit board to be corroded, and guarantees that the LED lamp normally uses, and is life-extending.

The utility model is achieved in that a kind of waterproof and dampproof LED Landscape Lamp, comprise shell, the plug with the water-vapor exchange passage, support, circuit board, be arranged on LED lamp pearl and clear lamp cover plate on circuit board, described shell comprises a die cavity and type groove, circuit board is arranged on the base plate of type groove, the LED driving power is arranged in die cavity, the two ends of plug and shell removably connect, and support and plug removably connect; Its special character is: comprise that also several have the lens of the inner chamber of opening, described lens cover LED lamp pearl and openend and circuit board and fit;

The surface of heat radiation sealed glue covering board mounted LED lamp bulb, and lens and circuit board are fixed together; Heat radiation sealed glue bonds together the length direction end face of circuit board and the wallboard of type groove, and the end face at the length direction two ends of heat radiation sealed glue covering board is also bonding with the base plate of type groove.

Described a kind of waterproof and dampproof LED Landscape Lamp, its special character is: the openend of described lens and circuit board are bonding with fluid sealant.

A kind of waterproof and dampproof LED Landscape Lamp of the utility model, owing to adopting such structure, the solder joint of LED lamp pearl and circuit board and the circuit of circuit board are isolated from the outside, and have good heat dispersion, thereby increase the service life.

Fig. 2 is stereogram of the present utility model.

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

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As Fig. 1, Fig. 2, shown in Figure 3, a kind of waterproof and dampproof LED Landscape Lamp, comprise shell 1, the plug 2 with the water-vapor exchange passage, support 3, circuit board 4, be arranged on LED lamp pearl 5 and clear lamp cover plate 6 on circuit board 4, described shell 1 comprises a die cavity 11 and type groove 12, circuit board 4 is arranged on the base plate of type groove 12, the LED driving power is arranged in die cavity 11, and plug 2 removably connects with the two ends of shell 1, and support 3 removably connects with plug 2;

The lens 7 that also comprise the inner chamber that several have opening, described lens 7 cover LED lamp pearl 5 and openend and circuit board 4 and fit;

The surface of heat radiation sealed glue 8 covering board 4 mounted LED lamp bulbs, and lens 7 and circuit board 4 are fixed together; Heat radiation sealed glue 8 bonds together the length direction end face of circuit board 4 and the wallboard of type groove 12, and the end face at the length direction two ends of heat radiation sealed glue 8 covering boards 4 is also bonding with the base plate of type groove 12.The steam heat exchange road discharge of the plug 2 of the heat band water-vapor exchange passage in die cavity 11 and type groove 12.

The openend of described lens 7 and circuit board 4 use fluid sealants are bonding.

Above-described is only preferential embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art, in the situation that do not break away from the utility model principle, can also make some improvement and modification, this also is considered as protection domain of the present utility model.
