Abstract

The utility model relates to a single lens type LED (Light-emitting Diode) flood light, which belongs to the technical field of LED lighting. A packaging mode of an existing LED flood light is poor in heat dissipation effect and high in cost. The single lens type LED flood light comprises a base plate, wherein the base plate is arranged on a support seat; a light source installing area is arranged in the center of an upper surface of the base plate; an LED light source plate, a lens and a compression ring are sequentially arranged on the light source installing area from bottom to top; the light source plate is fixedly arranged on the light source installing area through an installing plate; a plurality of SMD (Surface Mount Device) LED light beads are fixedly arranged on the light source plate; the lens is a hemispheric convex lens with one side being convex and one side being concave, covers the upper sides of the LED light beads, and is matched with the light source plate; a flange extending outwards is arranged on an outer ring of the lens; a fitting part corresponding to the flange is arranged on the bottom part of the compression ring; the compression ring covers the lens in a pressed manner so as to enable the fitting part to press against the flange, the lens is tightly compressed and fixed on the light source installing area through a screw; a plurality of cooling fins arrayed at intervals are respectively arranged on the upper surface (except for the light source installing area) and the lower surface of the base plate. The single lens type LED floodlight is quick to radiate heat, and has a good light emitting effect and lower production cost.

Description

A kind of simple lens formula LED Projecting Lamp

Technical field

The utility model belongs to the LED lighting technical field, and is especially relevant with a kind of simple lens formula LED Projecting Lamp.

Background technology

Because LED has advantages such as energy-saving and environmental protection, life-span length, has been widely used in the various light fixtures.A lot of outdoor Projecting Lamps have all adopted led light source as lighting source in a large number, existing LED Projecting Lamp is installed in a plurality of LED elements on the planar circuit board usually, from the LED encapsulation mode, LED encapsulating structure on the existing market is generally the high-power integrated encapsulation of LED or LED COB encapsulates to increase light-emitting area or improves brightness of illumination, but the high-power integrated encapsulation mode of LED makes thermal resistance big greatly because of power, heat radiation slowly, make led light source have substantial degradation service life, more existing factories also have by improving the radiator structure of LED Projecting Lamp, though can improve radiating effect, but complex structure makes production cost higher; And the relative aforesaid way assembling of LED COB encapsulation mode is simple, but production cost is higher at present, and utilization rate is not very general.

The utility model content

The purpose of this utility model is intended to overcome the existing defective that LED Projecting Lamp thermal resistance is big, radiating effect is bad, service life is low, and a kind of simple lens formula LED Projecting Lamp that dispels the heat quick, simple in structure, that bright dipping is effective is provided.

For this reason, the utility model is by the following technical solutions: a kind of simple lens formula LED Projecting Lamp, comprise substrate and bearing, substrate is installed on the bearing, it is characterized in that described upper surface of base plate center is provided with the light source installing zone, the light source installing zone is equipped with led light source plate, lens and pressure ring from the bottom to top successively, described led light source plate is fixedly installed in described light source installing zone by an installing plate, is installed with a plurality of paster LED lamp pearls on the led light source plate; Described lens are the recessed hemispherical convex lens of the protruding one side of one side, has good optically focused, lens cover is loaded on the led light source top and cooperates installation with described light source board, protect LED lamp pearl to improve simultaneously and light effect, outer ring, described lens bottom is provided with outward extending flange, and described pressure ring bottom is provided with the sticking part corresponding with described flange, and the pressure ring gland is on lens, sticking part is pressed against on the flange, lens are compressed and is fixed in light source installing zone on the substrate by screw; Described upper surface of base plate has effectively improved radiating rate except being equipped with spaced a plurality of radiating fin on light source installing zone and the lower surface.

Use the utility model can reach following beneficial effect: by with paster LED lamp pearl as led light source, make the light source spread heat, and substrate upper bottom surface and bottom surface be provided with radiating fin, improved radiating rate greatly, prolonged service life; Lens cooperate installation respectively with light source board, fixedly connected by the pressure ring cooperation simultaneously, have effectively improved light effect, protect paster lamp pearl simultaneously; Lens adopt the hemispherical convex lens of evagination indent, can realize the multiple different light effect that goes out, and optically focused effect simultaneously is very good, has directly saved the parts of reflector, and fitting structure is simplified, and has reduced production cost.
