Abstract

The utility model relates to an LED spot light which comprises a heat radiating element for fixing illuminating components, an external electronic drive and a plastic lampshade sleeved at the periphery of the heat radiating element. The illuminating component consists of LED lights and aluminum base board used for fixing LED lights, and each LED light is sleeved with a light-focusing component; the heat radiating element is provided with a groove, and the illuminating components which are inclined with each other are arranged in the groove of the heat radiating element. The LED spot light improves the structure of the prior LED spot light and installs illuminating sets which are inclined with each other in the groove of the heat radiating element, thereby increasing the light utilization rate and saving electrical energy; wherein, each illuminating set includes three or more than three illuminating components. In addition, since light from a plurality of illuminating components are overlapped and supplemented, the light evenness is improved, thereby achieving less brightness differences among all illuminated surfaces.

The utility model content
Technical problem to be solved in the utility model is the defective that overcomes prior art, and a kind of smooth good evenness, LED Projecting Lamp that utilization rate is high are provided.
The utility model is achieved through the following technical solutions: a kind of LED Projecting Lamp, comprise fixedly radiating piece, optically focused parts, the external electronic driver of luminescence component and the plastic lamp shade that is placed in the radiating piece periphery, described luminescence component is made up of the aluminium base of LED lamp and fixed L ED lamp, be with the optically focused parts on each LED lamp, the optically focused parts are lens or the reflector with different beam angles, radiating piece is provided with groove, and luminescence component is installed in the groove in the mode of mutual inclination.
Described luminescence component to be being one group more than three or three, and the two or more luminescence components in every group become the reverse inclination direction to be fixed in bottom portion of groove, and another or an above luminescence component are fixed on the groove center of radiating piece.
Described radiating piece is a stripe shape, and the groove in the radiating piece vertically is provided with, and is provided with conduit and the through hole that waterproof adhesive tape is installed in the radiating piece periphery.
External electronic driver electrically connects by outlet and LED lamp, outlet is interspersed in the waterproof plug, be fixed with the waterproof wire clamp on the waterproof plug, be lined with waterproof pad between waterproof plug and the radiating piece, waterproof plug, waterproof pad are fixed on the radiating piece by screw, and the waterproof adhesive tape of vertical setting is installed in the radiating piece periphery.
The utility model is by being provided with groove in radiating piece, bottom portion of groove is equipped with luminescence component, with three or three above luminescence components is one group, wherein two or more luminescence components become the reverse inclination direction to be fixed in bottom portion of groove, one or more luminescence components are fixed in the groove center, form three kinds of planes with different direction of illuminations, all be with the lens or the reflector of different beam angles on each LED lamp, the plane of three kinds of different direction of illuminations is in conjunction with the lens or the reflector of different beam angles, form a kind of asymmetric luminous intensity distribution, improve light utilization efficiency, saved electric energy; In addition, the light mutual superposition of a plurality of luminescence component irradiations is replenished, and makes the uniformity of light better, and face to be illuminated brightness separately is more or less the same.
