Abstract

The utility model relates to a full lighting-angle LED (light-emitting diode) bulb lamp which comprises a lamp cover, a reflection cup, LED light sources, a cooling fin and a lamp seat. A power supply is arranged on the inner side of the cooling fin, the LED light sources are arranged on the front portion of the cooling fin, the lamp cover is buckled on the upper portion of the cooling fin and the LED light sources, the lamp seat is installed on the rear end of the cooling fin, the LED light sources are fixed on the same cooling base board according to the light configuration requirement, the LED light sources distributed on the same cooling base board are separated into an outer part and an inner part by the frustum-shaped reflection cup, and a reflection membrane is arranged on the outer frustum surface of the reflection cup. According to the all-optical angle LED bulb lamp, the LED light sources distributed on the same cooling base board are separated into an outer part and an inner part by the frustum-shaped reflection cup, the light emitted by the outer part LED light sources are diffuse reflected through the reflection membrane layer of the outer frustum surface of the reflection cup to achieve the all angles lighting. The strong or weak of the main light and the back light can be achieved through the light resources distribution on the cooling base board.

Description

The LED bulb lamp of full optic angle

Technical field

The utility model relates to the LED lamp, refer in particular to here a kind of can wide-angle even the LED bulb lamp of full angle illumination.

Background technology

At present, full optic angle LED bulb lamp on the market, the generally illumination by many sides (three, on four sides, six faces) full optic angle of luminous realization, cost is high, around light is emitted as, under the low and lamp bottom of irradiation ground light efficiency without direct light, the bright vertical lower of lamp is bright not, the light efficiency utilization is poor, can cause like this waste of luminous energy, deviates from 10% the requirement that is not more than total light efficiency backlight of full optic angle LED bulb lamp.

The utility model content

The utility model provides a kind of LED bulb lamp of realizing full optic angle illumination for above-mentioned technical problem.

For achieving the above object, the utility model adopts following technical scheme:

The LED bulb lamp of full optic angle, it comprises lampshade, reflector, led light source, fin and lamp socket, in the fin installed inside power supply is arranged, led light source installation of heat radiator front end, lampshade is buckled in the top of radiator and led light source, and lamp socket is installed in the rear end of fin, and led light source need to be fixed on the same heat-radiating substrate with luminous intensity distribution, be distributed on the same heat-radiating substrate led light source and separated by the reflector of frustum and be inside and outside two parts, be provided with reflective membrane at the outer cone table top of reflector.

The reflexed light film of described reflector adopts vacuum coating, water film plating layer or reflectance coating pad pasting layer.

The beneficial effects of the utility model are: the utility model led light source on same heat-radiating substrate is separated by the reflector of frustum and is inside and outside two parts, the light that outer part led light source sends is realized the illumination of full angle by the reflexed light film diffuse reflection on the outer cone table top of reflector.Key light and strong and weak can the distribution by the led light source on the existing heat-radiating substrate backlight are realized.Cost is low, realizes simple.

Fig. 4 is the utility model three-dimensional exploded view.

The specific embodiment

The utility model is described in further detail below in conjunction with Figure of description:

See shown in Fig. 1-4, the LED bulb lamp of the disclosed full optic angle of the utility model, it comprises lampshade 1, led light source 3, fin 4 and lamp socket 5, in lamp socket 5 lower ends lamp holder 6 is installed, in fin 4 installed inside power supply is arranged, led light source 3 is installed fin 4 front ends, and lampshade 1 is buckled in the top of fin 4 and led light source 3, described lampshade 1 is the transparent body, and light can see through lampshade 1 and penetrate.Lamp socket 5 is installed in the rear end of fin 4, led light source 3 comprises center LED lamp body and all side LED lamp bodies, at the center LED lamp body outside back-off reflector 2 of frustum is arranged, be provided with reflexed light film at the outer cone table top of reflector 2, all side LED lamp bodies and center LED lamp body are separated by reflector.Week side LED lamp body arranges its position and number on substrate according to light distribution requirements.

The reflexed light film of described reflector 2 adopts vacuum coating, water film plating layer or reflectance coating pad pasting layer.

Wherein vacuum coating is present ripe technique for vacuum coating, and the water depositing process is also comparatively common, or directly uses the reflectance coating attaching to obtain.

The utility model led light source on same heat-radiating substrate is separated by the reflector 2 of frustum and is inside and outside two parts, and the light that outer part led light source sends is realized the illumination of full angle by the reflexed light film diffuse reflection on the outer cone table top of reflector 2.Key light and strong and weak can the distribution by the led light source on the existing heat-radiating substrate backlight are realized.Cost is low, realizes simple.

The above only is to preferred embodiment of the present utility model; be not that scope of the present utility model is limited; so under the prerequisite that does not break away from the utility model design spirit; the equivalence that the common engineers and technicians in this area do structure described in the utility model, feature and principle changes or decorates, and all should fall in the protection domain that the utility model applies for a patent.

Claims

1. the LED bulb lamp of full optic angle, it comprises lampshade, reflector, led light source, radiator and lamp socket, in the fin installed inside power supply is arranged, led light source installation of heat radiator front end, lampshade is buckled in the top of fin and led light source, and lamp socket is installed in the rear end of fin, it is characterized in that, led light source on the same heat-radiating substrate is separated inside and outside two parts by the reflector of frustum, is provided with reflexed light film at the outer cone table top of reflector.
