The novel LED projector lamp comprises a housing, wherein the bottom of the housing is arranged on a supporting seat; the outer bottom surface of the housing is provided with heat radiating fins; the inner bottom of the housing is respectively provided with light reflection cups, two groups of light emitting assemblies, a glass plate and a pressing cover from bottom to top; each light emitting assembly comprises an LED light source, a light source plate and a lens; the LED light source comprises paster LED light beads; the lens is a semi-spherical convex lens with a convex surface and a concave surface, the outer circle of the lens is provided with a flange extending outwards, and a lens cover is arranged above the LED light source and is matched with the light source plate; the number of the light reflection cups corresponds to that of the light emitting assemblies, the bottom of each cup body is provided with a round through hole corresponding to the lens, the bottom of the cup body is pressed and arranged on the flange, the top of the cup body is provided with an extensional installing part which is fixedly connected with the housing through screw nails; and the glass plate is tightly compressed and fixedly arranged on the housing through the pressing cover. The novel LED projector lamp is quick in heat radiation, good in light emitting effect and lower in production cost.

Description

A kind of New LED Projecting Lamp

Technical field

The utility model belongs to the LED lighting technical field, and is especially relevant with a kind of New 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, because LED has specific lighting angle, the light of the LED element emission of planar alignment penetrates with the direction on perpendicular circuit board plane basically, causes at the hot spot of Projecting Lamp the place ahead formation less.There is producer to use reflector that hot spot is increased, big but traditional reflector goes out light loss in use, reduce result of use; 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, simultaneously cost is increased relatively; And LED COB encapsulation mode is assembled simply comparatively speaking, but production cost is higher at present, and utilization rate is not very general.

The utility model content

It is big that the purpose of this utility model is intended to overcome existing LED Projecting Lamp encapsulation mode thermal resistance, and service life is low, goes out the light effect defect of bad, and a kind of long service life, the effective New LED Projecting Lamp of bright dipping are provided.

For this reason, the utility model by the following technical solutions: a kind of New LED Projecting Lamp, comprise housing and bearing, housing bottom is installed on the bearing; The housing outer bottom is provided with radiating fin, the housing inner bottom part is respectively equipped with luminescence component, reflector, glass plate and gland from the bottom to top, described luminescence component comprises the light source board of led light source and fixed L ED light source and the lens with optically focused effect, it is characterized in that, described luminescence component quantity is two groups, described led light source is paster LED lamp pearl, can make the light source spread heat, improves service life; Described lens are the recessed hemispherical convex lens of the protruding one side of one side, and the lens outer ring is provided with outward extending flange, and lens cover is loaded on the led light source top and cooperates installation with described light source board; Described reflector quantity is corresponding with luminescence component, each bottom of cup is provided with the manhole corresponding with lens, bottom of cup press-fits on the flange of described lens, the cup top is provided with the installation portion that extends outward, described installation portion is fixedlyed connected with housing by screw, make reflector closely be connected with lens, improve and light effect; Described glass plate is fixed by gland and housing.

As to technique scheme replenish and perfect, the utility model also comprises following technical characterictic.

Described two reflector cups have superposed part, and this intersection breach communicates two reflector inner chambers.

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, improved service life, and production and processing is easy, technology difficulty is lower, has reduced production cost; By two groups of luminescence components are installed in the same housing, effectively improve illumination brightness and increase range of exposures; Lens respectively with the installation that closely cooperates of light source board and reflector, effectively improved and light effect, protect paster lamp pearl simultaneously; Lens adopt the hemispherical convex lens of evagination indent, and the corresponding reflector cup of each lens, can realize the multiple different light effect that goes out, and adapt to various environment light needs.
