Description

A kind of LED decorative lamp

Technical field

The utility model relates to a kind of LED lamp more particularly to a kind of LED decorative lamps.

Background technique

LED light source is a kind of solid light source, due to its is small in size, fast response time, it is photochromic it is pure, low energy consumption, energy conservation and environmental protection, The advantages that service life is long is by the favor of illuminating industry, referred to as " green illumination light source ".LED light source is initially often used as indicating Lamp, display board etc., with the continuous progress of technology, LED be widely used in various instruction display backlights, decor, In the fields such as landscape light in city.

However, as ornament lamp, the substrate selected is mostly the opaque materials such as aluminium, due to one in LED lamp design Part light is blocked, so that the angle of divergence of light at most only has 180 °, the utilization rate of light is low.Secondly, LED chip is formed by light Unevenly, the high directivity of light, dazzling hot spot easy to form, and illumination effect is single, influences decorative effect.

Chinese patent 201020287415.9 propose it is a kind of enable light be refracted and/or diffusing reflection after project lampshade dress Adorn illuminator, light by it is random decompose, mixing, again decompose, again mixing ..., and be divided and the number of light mixing It is all random with effect, to enable the change of light coloring, lamplight brightness full of randomness.However the decorative illumination lamp is The color and brightness change for enriching light, do not increase new decorative elements, the randomness that color, brightness change but also These decorative elements are disorderly and unsystematic, and actual decorative effect is poor, and the utilization rate of light is relatively low.

Summary of the invention

The purpose of this utility model is to provide a kind of LED decorative lamps.On the one hand, guarantee that the angle of divergence of light reaches maximum, On the other hand, overcome the limitation of LED chip itself, not only prevented the generation of dazzling hot spot, but also guarantee that illuminating effect takes into account decoration The diversity and regularity of element.

In order to achieve the above objectives, the utility model uses following technical scheme:

Multiple anaclasis and/or scattering are carried out including pedestal, setting being used for made of translucent material on the base Lampshade and the light-transmissive substrates that are arranged in the lampshade, multiple LED chips are provided in the light-transmissive substrates, in LED chip It is provided with phosphor powder layer, each LED chip is vertically alternatively arranged in light-transmissive substrates.

Preferably, the lampshade is made of diffuser plate or prism plate.

Preferably, the lampshade uses the polyhedron being spliced by muti-piece diffuser plate or prism plate, alternatively, lampshade uses It is surrounded on the diffuser plate of the arc outside light-transmissive substrates.

Preferably, the light-transmissive substrates are used by rigid transparent material (such as organic glass, ito glass) or flexible and transparent material Expect plate body made of (such as PVC plastic).

Preferably, the pedestal includes the card slot being connected with light-transmissive substrates.

Preferably, the phosphor powder layer is coated on after mixing fluorescent powder according to mass ratio 1:10~1:30 with silica gel It is made in LED chip.

Preferably, the fluorescent powder includes one of yellow fluorescent powder, red fluorescence powder, green emitting phosphor or a variety of, LED chip emits blue light.

Preferably, each LED chip is supported on above pedestal by light-transmissive substrates, is provided in light-transmissive substrates each for connecting The circuit of LED chip and external power supply (plant-grid connection position is at the card slot of pedestal).

The beneficial effects of the utility model are embodied in:

In the utility model, light that LED chip and phosphor powder layer issue by lampshade Multiple Scattering, refraction (for example, by Constitute the diffuser plate or prism plate of lampshade), and increase light-emitting angle by light-transmissive substrates, not only increase the scattering of emergent ray It is dazzling since light is excessively concentrated to solve LED light source so that the dispersibility and uniformity of light are significantly improved for degree The problem of.Meanwhile also making illuminating effect no longer unification, have polychromatic light hot spot, mono-chromatic lamp cover lines of outline and more The decorative elements of a variety of organic assemblings such as astigmatism shadow atmosphere, decorative performance significantly improve.

Further, in the utility model, substrate, the material source of diffuser plate are extensive, cheap, production cost compared with It is low.

Further, in the utility model, the assembled shape of diffuser plate or prism plate can carry out a variety of different designs, Lampshade shape has very big flexibility, and illumination and decoration effect caused by different lampshade shapes is different, the same shape Lampshade is also different in the effect that different angle is seen.
