Abstract

The utility model discloses a semi-ellipsoidal luminous light beam direct-inserting LED lamp, which relates to the field of LED lighting technology. The semi-ellipsoidal luminous light beam direct-inserting LED comprises two LED brackets and an epoxy resin package main body, wherein the top end of one LED bracket is provided with a reflecting cup, the reflecting cup comprises a cup bottom and a cup port, the cup bottom is elliptic or circular, and the cup port is in a circular or elliptic shape with a notch; and the epoxy resin package main body is provided with a bottom surface, the epoxy resin package main body is cut by a cross section vertical to the bottom surface to form an optical reflecting surface, and the plane on which the notch of the cup port is positioned is parallelly arranged with the optical reflecting surface. The semi-ellipsoidal luminous light beam direct-inserting LED lamp has the beneficial effects that: the light rays emitted by LED wafers can be distributed to areas below the horizontal line, the light utilization rate is improved, high display effect can be achieved by using wafers of low luminance, thereby reducing the cost, and satisfying the display demands in a particular direction.

Description

A kind of semielliptical shape luminous beam straight cutting LED lamp

[technical field]

The utility model relates to a kind of LED lighting, and in particular, the utility model relates to a kind of semielliptical shape luminous beam straight cutting LED lamp.

[background technology]

Along with the LED full color display is universal day by day, particularly outdoor display screen with its rich color and round-the-clock broadcast performance, is favored by users deeply.Because common straight cutting LED encapsulating structure, enclosure support structure are horizontal, vertically symmetrical, make light beam on level, vertical direction, also be symmetrically distributed, adopt this light source to make display screen, when using out of doors, can make the above light directive sky in horizontal line zone, thereby cause waste; In some specific application places, unnecessary beam distribution can cause the light pollution problem especially, influences resident's normal life.

[utility model content]

The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, and a kind of semielliptical shape luminous beam straight cutting LED lamp is provided, and the luminous beam of this LED lamp is distributed in horizontal line with lower area, has improved light utilization efficiency.

The technical solution of the utility model is achieved in that it comprises two led supports and an epoxy encapsulation main body, wherein the top of a led support has a reflector, at the bottom of described reflector has glass and rim of a cup, its improvements are: described rim of a cup is have a breach circular or oval for oval or circular at the described cup end; Described epoxy encapsulation main body has a bottom surface, and this epoxy encapsulation main body cut by a cross section vertical with the bottom surface, forms an optical reflection face, and plane and the optical reflection face at the breach place of described rim of a cup be arranged in parallel;

In the said structure, the cross section of described epoxy encapsulation main body is a half elliptic, and the top of epoxy encapsulation main body is seamlessly transit spherical;

In the said structure, described two led supports are respectively anodal support and negative pole support, and described reflector namely is arranged on the anodal support;

In the said structure,, fixedly there is a LED wafer at the cup end of described reflector.

The beneficial effects of the utility model are: the utility model is fixed on the light beam that sends of LED wafer at the cup end of reflector, reflection by reflector on the support, make light beam to the reflection stack of horizontal line below, secondary optics by the epoxy encapsulation main body reflects again, make distribution of light arrive horizontal line with lower area, improved light utilization efficiency, can use the brightness wafer of telling somebody what one's real intentions are to obtain high display effect, thereby reduce cost, can satisfy the demonstration demand on specific direction.

[embodiment]

The utility model will be further described below in conjunction with drawings and Examples.

With reference to shown in Figure 1, the utility model has disclosed a kind of semielliptical shape luminous beam straight cutting LED lamp, this LED lamp comprises two led supports 10 and an epoxy encapsulation main body 20, two led supports 10 are respectively anodal support 101 and negative pole support 102, in actual production, for the ease of distinguishing, two led supports different in size,, in the present embodiment, in conjunction with Fig. 2, wherein long led support is anodal support 101, another support of lacking some then is negative pole support 102, and with reference to shown in Figure 3, anodal support 101 tops have a reflector 30, at the bottom of this reflector 30 has glass 301 with rim of a cup 302, with reference to Fig. 4, the cup end 301 is oval, and cup is installed with one and is used for luminous LED wafer at the end 301; Rim of a cup 302 is the ellipse with a breach, and rim of a cup 302 is more bigger than the cup ends 301, so that reflector 30 integral body are the shape of similar round platform.

With reference to Fig. 5 and in conjunction with Fig. 2, above-mentioned epoxy encapsulation main body 20 has a bottom surface 201, this epoxy encapsulation main body 20 is cut by a cross section vertical with bottom surface 201, thereby form an optical reflection face 202, the top of epoxy encapsulation main body 20 is seamlessly transit spherical, this structure can be regarded a cross section as for oval, top are spherical cylinder, and the shape that the back forms is cut on a plane that is parallel to the cylinder center line.With reference to Fig. 1, Fig. 2, epoxy encapsulation main body 20 is fixed on above-mentioned led support 10 tops, reflector 30 is wrapped, and plane and the optical reflection face 202 at the breach place of rim of a cup 302 be arranged in parallel, this structure Design, the light beam that the feasible LED wafer that is fixed on the cup end 301 of reflector 30 sends is by the reflection of reflector 30, make light beam to the reflection stack of horizontal line below, secondary optics by epoxy encapsulation main body 20 reflects again, make distribution of light arrive horizontal line with lower area, improved light utilization efficiency, can use the brightness wafer of telling somebody what one's real intentions are to obtain high display effect, thereby reduce cost, can satisfy the demonstration demand on specific direction.

Described above only is preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, various distortion and modification can appear, and the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.
