Description

A kind of LED floodlight

Technical field

The utility model relates to the outdoor lighting equipment technical field, particularly a kind of LED (light emitting diode) floodlight.

Background technology

Floodlight in the market generally with incandescent lamp or electricity-saving lamp, but does not have LED Lantern Festival ability; And not having the LED lamp long-lived, the life-span of LED lamp can reach more than 50,000 hours, can be operated in fast state; And if frequent startup or the pass filament breaking of electricity-saving lamp will turn black, break down soon.The LED lamp can solid-stately encapsulate, and belongs to the cold light source type, and convenient transportation and installing can be installed in the equipment of any miniature and sealing, is not afraid of vibration; The environmental protection of LED lamp does not have harmful substances such as mercury in addition.Though existing floodlight also has utilization LED lamp, because it is combined as the master with single integrated optical source mostly, radiating effect is bad, and development cost is high, safeguards inconvenience etc.

The utility model content

The utility model provides that a kind of cost is low, the LED floodlight of good heat dissipation effect.

To achieve these goals, the utility model provides following technical scheme:

A kind of LED floodlight, it comprises: lamp housing, mounting bracket, reflection shield, cloche, power pack, heat conduction copper sheet and LED lamp, wherein:

Said LED lamp links to each other with said power pack; Said power pack is placed in the power pack; Said power pack and said heat conduction copper sheet are installed in the medial surface of said lamp housing bottom, and said LED lamp is fixedly installed on the said heat conduction copper sheet, also is equiped with reflection shield, cloche on the said lamp housing; And the LED lamp is stated in said reflection shield, said cloche and said jacket residence, and said lamp housing outside also is equiped with mounting bracket.

Preferably, said lamp housing comprises drain pan and face-piece, and said drain pan and said face-piece are fixed together through securing member.

Preferably, said drain pan is provided with continuous convexity.

Preferably, said securing member is screw rod and is assemblied in the nut on the said screw rod.

Preferably, said LED lamp is fixed on the said heat conduction copper sheet through screw.

Through implementing above technical scheme, have following technique effect: the LED floodlight that the utility model provides embeds the heat conduction copper sheet in the middle of lamp housing, can play better radiating effect, and simple in structure, easy to maintenance.

Description of drawings

The exploded view of the LED floodlight that Fig. 1 provides for the utility model embodiment;

The installation diagram of the LED floodlight that Fig. 2 provides for the utility model embodiment.

The specific embodiment

In order better to understand the technical scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.

The utility model embodiment provides a kind of LED floodlight; As depicted in figs. 1 and 2; It comprises: lamp housing, mounting bracket 107, reflection shield 103, cloche 113, power pack 108, heat conduction copper sheet 102 and LED lamp 106; Said lamp housing comprises drain pan 101 and face-piece 112, and said drain pan 101 is installed in face-piece 112 and forms said lamp housing together, and said drain pan 101 is the bottom of said lamp housing.Concrete, said drain pan 101 and said face-piece 110 are fixed together through securing member.More concrete, said securing member is screw rod 111 and is assemblied in the nut 110 on the said screw rod 111.To increase the fastness of this LED floodlight.This lamp housing is an aluminium section bar, easily heat radiation.

Said LED lamp 106 links to each other with said power pack 108; Said power pack 108 is placed in the power pack; Said power pack and said heat conduction copper sheet 102 are installed in the medial surface of said drain pan 101, and be concrete, and said heat conduction copper sheet 102 is embedded on the medial surface of said drain pan 101; Said LED lamp 106 is fixedly installed on the said heat conduction copper sheet 102; Preferably, said LED lamp 106 is fixed on said heat conduction copper sheet 102 the above said lamp housing through screw and also is equiped with reflection shield 103, cloche 113, and said reflection shield 103 is fixed on the said drain pan 101 through said face-piece 112 with said cloche 113.LED lamp 106 is stated in said reflection shield 103, said cloche 113 and said jacket residence, and said lamp housing outside also is equiped with said mounting bracket 107, and this mounting bracket 107 is used for this LED floodlight is installed in suspension place.This LED floodlight embeds the heat conduction copper sheet in the middle of lamp housing, can play better radiating effect.

In a further embodiment; The bottom of said lamp housing is provided with continuous convexity; Be that said drain pan 101 is provided with continuous convexity, this convexity has increased area of dissipation, helps better heat radiation; The heat conduction copper sheet can export to the heat that the LED lamp is distributed on the drain pan as soon as possible, helps faster and better heat radiation.

In addition; Be provided with first water-proof silica-gel 105 between said drain pan 101 and the said face-piece 112; The frame of said cloche is provided with second water-proof silica-gel 104; Said power pack 108 is provided with the 3rd water-proof silica-gel 109, and it is inner that these water-proof silica-gels are used to prevent that dust and water from getting into said LED floodlight.

Said reflection shield 103 adopts safety glass with cloche 113, to reach better reflective fruit.

More than a kind of LED floodlight that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
