Abstract

A wide-angle LED (Light Emitting Diode) lamp comprises a lamp holder, LED light sources and a lamp cover which covers exteriors of the LED light sources; a vertical column which extends into the lamp cover is arranged on the lamp holder; a PCB (Printed Circuit Board) which is perpendicular to the vertical column is installed on the end portion of the vertical column; the LED light sources are distributed and packaged on the upper surface and the lower surface of the PCB; the PCB is a transparent board. According to the wide-angle LED lamp, light emitted from the integral LED lamp can cover a wide range due to the fact that the LED light sources are packaged on the upper surface and the lower surface of the transparent PCB; a lead is protected, space is saved, and the attractive appearance of the integral lamp is guaranteed due to the fact that the lead hides inside the vertical column which is hollow; LED lamp production and maintenance are convenient and lamp production costs are reduced due to the facts that a driving power source which drives the LED light sources to operate utilizes an IC (Integrated Circuit) and the LED light sources and the IC are packaged on the PCB.

Description

A kind of wide-angle LED lamp

Technical field

The utility model relates to a kind of improvement technology of LED light fixture, specifically a kind of comprehensive irradiant wide-angle LED lamp.

Background technology

The shortcomings such as everyone knows, it is high that traditional incandescent lamp has energy consumption, and efficiency is low.Based on energy-conservation and consideration environmental protection, incandescent lamp is all progressively being planned to stop continuing to sell in the ground such as North America, Europe, Japan and Taiwan.LED bulb lamp, has the advantages such as high brightness, low-power consumption, long-life and environmental protection due to it, become the first-selection that substitutes conventional incandescent.But, because LED is directional light, need to there is a kind of effective light figure conversion regime to realize and convert low-angle bright dipping to omnibearing bright dipping.For all-directional illumination, the star of american energy has been made strict difinition, that is: within the scope of 0o-135o vertical angle light intensity change should be mild, the light intensity at any angle in this interval, must be between the 80%-120% of this interval average intensity value, at least 5% of total light flux need be between 135o-180o.

Analyze technically, want to replace conventional incandescent, generally adopt two kinds of means, a kind of is to utilize optical element, as lens, speculum and diffuser etc. regulate luminous pattern, makes it to produce omnibearing luminous.Another is by the arrangement to the 3 D stereo of LED chip, allow chip in all directions to go out light intensity distributions even.

The comprehensive LED modulated structure of existing major part is more complicated, is unpack format between LED light source and driving power, easy care not, and cost is also higher, is difficult to apply.

Summary of the invention

For above-mentioned prior art, the technical problems to be solved in the utility model is to provide that a kind of light range of exposures is wide, the wide-angle LED lamp of science simple for structure.

In order to address the above problem, the utility model adopts following technical scheme to realize:

A kind of wide-angle LED lamp, comprise lamp holder, LED light source and the lampshade that covers in LED light source outside, on lamp holder, be provided with a column extending in lampshade, in post end, the pcb board that one vertical pillars arranges is installed, LED light source distributes and is packaged in upper surface and the lower surface of this pcb board, and this pcb board is transparent panel.

As the improvement to such scheme, described column is hollow, and the wire connecting between lamp holder and LED light source is arranged in column.

As further improvement of these options, described LED light source is connected with the integrated IC that guarantees its operating voltage, and this integrated IC and LED light source are all packaged on pcb board.

The utility model is packaged in transparent pcb board upper surface and lower surface by LED light source, and the light that whole LED lamp is sent can cover wider scope, forms all-directional illumination.And the column that adopts hollow, is hidden in wire in column, gets final product guardwire, can save space again, guarantee the attractive in appearance of light fixture integral body.Meanwhile, the driving power of driving LED light source works has adopted integrated IC, and LED light source and integrated IC are all packaged on pcb board, has facilitated making and the maintenance of such LED lamp, has reduced the cost of manufacture of light fixture.

Accompanying drawing explanation

Fig. 1 is the utility model embodiment cross-sectional view.

The specific embodiment

In order to allow those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further elaborated.

As shown in Figure 1.The wide-angle LED lamp monnolithic case that the present embodiment discloses is consistent with existing most of LED ball bulb, the glass lampshade 3 processed that has lamp holder 1, LED light source 2 and cover in the printing opacity of LED light source 2 outsides.

Compare with existing LED lamp, the improvements of the present embodiment maximum for being provided with a column 4 extending in lampshade 3 on lamp holder 1, the pcb board 5 that one vertical pillars 4 arranges is installed in column 4 ends, LED light source 2 is a plurality of, distribute and be packaged in upper surface and the lower surface of this pcb board 5, by column 4, make each LED light source 2 be positioned at the center that approaches of lampshade 3, be more conducive to light and disperse to surrounding.And this pcb board 5 has adopted transparent panel.Under this version, each LED light source 2 can emit beam to multiple directions, and light can cover wider scope, forms all-directional illumination, by test, can meet the all-directional illumination specification requirement of the star definition of american energy completely.

In addition, the column 4 of the present embodiment design is hollow, and the wire connecting between lamp holder 1 and LED light source 2 is arranged in column 4.This structure is guardwire effectively, can save space again, guarantees the attractive in appearance of light fixture integral body.

And, in order to facilitate making and the maintenance of LED lamp, reduced the cost of manufacture of light fixture, the driving power of assurance LED light source 2 operating voltages that adopt in the present embodiment is integrated IC6, LED light source 2 is directly connected with integrated IC6, and this integrated IC6 and LED light source 2 are all packaged on pcb board 5.

The integrated IC6 adopting in the present embodiment is existing technology, can direct commercially available acquisition, at this, do not repeat.In addition, for the quantity of the LED light source 2 of pcb board 5 upper surfaces and lower surface, can require determine according to the power of whole LED lamp etc., at this, also not be restricted.

It is more than preferably implementation of the utility model; it should be noted that; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art be when can make various corresponding changes and distortion according to the utility model, but within these changes and distortion all should belong to protection domain of the present utility model.
