Abstract

The utility model discloses an LED (light-emitting diode) bulb light, comprising a light cover, a heat dissipation platform, a power supply driving device and a light holder. The LED bulb light is characterized in that the upper end of the heat dissipation platform is an upward projection, the top surface and the side wall of the projection are provided with an LED assembly respectively, and the LED assemblies are connected with the power supply driving device. According to the LED bulb light disclosed by the utility model, the upper end of the heat dissipation platform is the upward projection, and the LED assemblies are fixed on the top surface and the side wall of the projection, thus lights emitted by LED can be irradiated to the upward side and the periphery and also can be irradiated sideway and downward, the defect that the original technical light emitting distribution is uneven is overcome, light emitting range of the LED bulb light is effectively increased, and full-angle light emitting is basically realized.

Description

The LED bulb lamp

Technical field

The utility model relates to a kind of light fixture, specifically is a kind of LED bulb lamp.

Background technology

Because characteristics such as long service life, the energy consumption of LED lamp are low, it has been widely used in the daily life as light source, such as the LED bulb lamp.The LED bulb lamp of prior art comprises lampshade, LED lamp, heat radiation platform, power source drive device and lamp holder.Said lampshade is fixed on the heat radiation platform, and the LED lamp is positioned at lampshade, and the LED lamp is connected with power source drive device; Power source drive device is connected with lamp holder, lamp holder is fixedly connected through the lower end of lamp bracket with the heat radiation platform, and the upper surface of the platform that dispels the heat is a level; The LED lamp is fixed on heat radiation platform upper surface; The luminous directionality spatially of this LED bulb lamp is very strong, and luminescence distribution is inhomogeneous, and general light emitting region is all in 180 degree; Scope beyond 180 degree just can't shine, and this just lets the use of LED bulb lamp receive certain restriction.Moreover the lampshade of the LED bulb lamp of prior art is processed by glass basically, when installing or transporting, is easy to fragmentation.

The utility model content

The technical problem that the utility model will solve provides the wide LED bulb lamp of a kind of light emitting region.

In order to achieve the above object; The technical scheme that the utility model provides is: a kind of LED bulb lamp; Comprise lampshade, heat radiation platform, power source drive device and lamp holder; The upper end of said heat radiation platform is provided with the LED assembly for convexity upwards, protruding top end face and sidewall, and the LED assembly links to each other with power source drive device.

As preferably, said convexity is a cylindrical protrusions, and said LED assembly is positioned on the top end face and outer circumference surface of cylindrical protrusions.This structural design can make the LED assembly distribute around the outer circumference surface of cylindrical protrusions, makes that the luminescence distribution of LED bulb lamp is more even.

As preferably, said LED assembly comprises a plurality of paster LEDs and flexible PCB, and a plurality of paster LEDs all are connected on the flexible PCB, and flexible PCB is fixed on the protruding top end face and sidewall.Paster LED need not the warm lamp time, and it is faster than general electric light to light response speed, and electro-optical efficiency is high, and power consumption is little, and flexible PCB then can free bend, make things convenient for layout, and the flexible PCB thermal diffusivity is good, helps the paster LED heat radiation.

As preferably, said a plurality of paster LEDs evenly distribute on flexible PCB.This structural design make paster LED luminous brightness even, avoid occurring local dim situation.

As preferably, said lampshade is a plastic lamp shade.Plastics are difficult for breaking into pieces, can play a protective role to the whole LED bulb lamp.

After adopting technique scheme, the utility model compared with prior art has the following advantages: the heat radiation platform upper end of the utility model LED ball bubble is convexity upwards; The LED assembly is fixed on the protruding top end face and sidewall; The light that sends of LED can not only shine the top with all around like this, also can shine oblique below simultaneously, overcomes the uneven shortcoming of original technological luminescence distribution; Effectively increase the light emitting region of LED bulb lamp, accomplish that basically full angle is luminous.
