Description

Sources illuminating structure with directive property

Technical field

The utility model provides a kind of sources illuminating structure with directive property, especially a kind of to use rigid LED filament The sources illuminating structure with directive property being composed with Double-layered transparent cover.

Background technique

In general illumination field, the luminescence component of light emitting diode (LED, Light Emitting Diode) application, And since it has many advantages, such as small in size, long service life, also, with environmental protection realize with carbon reduction it is gradually surging, more Old fluorescent lighting fixture is replaced with LED lamp come more multi-user, thus be widely used in the mankind daily life it In.With the fast development of lighting engineering, there is the LED incandescent lamp bulb for peddling a kind of pseudo-classic style tungsten lamp on the market at present, One or more light emitting diode filament (LEDF, Light Emitting Diode Filament) is mainly installed in by it In one light bulb, the tungsten wire illumination effect such as conventional incandescent is presented by LED filament, makes LED incandescent lamp bulb that there is trend of back-to-ancients Characteristic.

However, although the LED incandescent lamp bulb of the prior art for traditional LED spherical lamp bubble compared to having an opportunity to change It is apt to the problem that its weight is big and price is high, but the LED incandescent lamp bulb of the either aforementioned prior art or traditional LED ball type Light bulb itself because there is the metric system shape that has limited therefore fixed lamp holder must be used, in addition to this LED of the prior art is incandescent Still there are many potential problems for light bulb, such as due to the characteristic of LED high directivity, in order to reach similar conventional incandescent light bulb The wide-angle of complete cycle light and the illuminating effect of large area must then configure a large amount of filament, in addition to have fragile structure and assembling it is good Doubt in rate also expends various in material cost, built-up time and assembling cost, and LED illumination lamp is maximum at present Problem is still heat dissipation, and a large amount of LED filaments that must be tightly configured in order to modelled after an antique form the heat dissipation of illuminator Acid test.Because general configuration is to be in rolled form by long and narrow LED filament lamp bar and configure in traditional bulb-shaped shape shell In vivo, so heat dissipation is relatively difficult, therefore not only accelerate the luminous efficiency decline of LED filament, but also influence the longevity of LED grain Life, so the heat-sinking capability that how improve LED filament is the important issue of current LED illumination lamp.Because of foregoing problems, institute The wattage of LED filament is reduced with many manufacturers, reduces when LED filament is lighted and generates heat, but relative luminance is also dropped It is low, think that general bulb lamp will become primary illumination in the market, brightness is approximately in 1000 lumens or so, and currently on the market The brightness of some LED incandescent lamp bulbs then barely half, therefore current LED incandescent lamp bulb can only work as decorative lighting at most With, and primary illumination can not be worked as.

Therefore, after observing above-mentioned missing, and there is the generation of the utility model then.
