Description

A kind of LED light fixture

Technical field

The utility model relates to a kind of LED light fixture that is used for normal lighting.

Background technology

The LED lighting apparatus enjoys great popularity as energy-conservation lighting apparatus; Use just more and more widely; But up to the present; The LED lighting apparatus mainly locates to bring into play enormous function at automotive lighting, billboard, dance hall, theater etc., that is to say that high bright demonstration and environmental decoration more are partial in the effect of LED illumination, seldom is used for normal lighting.Tracing it to its cause, is because led light source is a cold light source, and when illumination, undressed light is too dazzling gorgeous, and illumination effect is poor, and light efficiency is not soft, causes people's kopiopia during normal lighting easily.

Summary of the invention

The goal of the invention of the utility model provides a kind of novel structure, and illumination effect is good, the soft not dazzling LED light fixture of light efficiency.

In order to realize the foregoing invention purpose, the technical scheme below the utility model has adopted:

A kind of LED light fixture comprises PC substrate, LED lamp, first crystalline lens and second crystalline lens, and the LED lamp is fixedly mounted on the PC base plate bottom; The said first crystalline lens top is provided with the light trough that holds the LED lamp, and the LED lamp is in the light trough; The said second crystalline lens top is provided with the cavity volume that opening makes progress, and the lateral wall of second crystalline lens is provided with installation base, and first crystalline lens is in the cavity volume of second crystalline lens.

As preferably, the cavity volume wall of said second crystalline lens is a frosting, scribbles the dope layer that adds lustre on the frosting, and the dope layer that adds lustre to makes lighting effect further improve.

As preferably, said first crystalline lens and second crystalline lens are all rounded.

As preferably, the said first crystalline lens bottom surface is an inner concave, and the inner concave effect is to cooperate the cavity volume bottom surface, makes light on inner concave, reflect and reflects different angles, further improves light efficiency.

As preferably, said first crystalline lens and second crystalline lens all are square.

As preferably, said installation base is in the top of the second crystalline lens lateral wall, and installation base and second crystalline lens are connected as a single entity.

As preferably, said light trough and interior LED lamp thereof are many groups.

Adopted a kind of LED light fixture of technique scheme; The LED lamp all is in the corresponding light trough of first crystalline lens; The light that the LED lamp sends reaches in the cavity volume of second crystalline lens all through first crystalline lens again, because of first crystalline lens and second crystalline lens equipped; Light through many times reflection and refraction, finally shines out with multi-angle between two lens.This through the LED light fixture that passes light in two lens novel structure not only, and good illumination effect, light efficiency is soft not dazzling, and then suitable normal lighting.

Description of drawings

Fig. 1: the cross-sectional view of the utility model embodiment.

The specific embodiment

Below in conjunction with Fig. 1 the specific embodiment of the utility model is done a detailed explanation.

A kind of LED light fixture as shown in Figure 1; Comprise PC substrate 1, organize LED lamp 12, first crystalline lens 2 and second crystalline lens 3 more; Many group LED lamps 12 are fixedly mounted on PC substrate 1 bottom; The both positive and negative polarity that specifically is every group of LED lamp 12 is connected on the PC substrate 1, gathers through line layer and connects two current supply lines.First crystalline lens, 2 tops are provided with the many groups light trough 22 that holds the LED lamp; LED lamp 12 quantity Matching of the quantity of light trough 22 and PC substrate 1 bottom; The position is corresponding with LED lamp 12; Every group of LED lamp 12 joined a light trough 22 and extended in its corresponding light trough 22, and promptly this light fixture all is in the light trough 22 of first crystalline lens as the luminous LED lamp 12 that rises, and the light that above-mentioned LED lamp 12 sends is all through first crystalline lens 2.First crystalline lens, 2 bottom surfaces are inner concaves; Second crystalline lens, 3 tops are provided with the cavity volume 31 that opening makes progress, the form fit of the shape of cavity volume 31 and first crystalline lens 2, and first crystalline lens 2 is in the cavity volume 31 of second crystalline lens 3.The cavity volume wall of second crystalline lens 3 is frostings, scribbles the dope layer 32 that adds lustre on the frosting.The lateral wall of second crystalline lens 3 is provided with installation base 33; Installation base 33 positions are in the top of second crystalline lens, 3 lateral walls; And the edge at second crystalline lens, 3 lateral wall tops, edge specifically is a ring rib that is connected as a single entity with second crystalline lens 3 around setting.Second crystalline lens 3 is installed the whole LED light fixture through the installation base 33 in its outside again.Be in the below and the side of LED lamp 12 luminous back light directive first crystalline lens 2 in the light trough, promptly can reach the luminous of 270 degree, illumination effect is good; The light that these LED lamps 12 are launched all is to see through first crystalline lens 2 in the cavity volume 31 of second crystalline lens 3, to reflect for more than 32 time and refraction through the dope layer that adds lustre to again; This through passing the LED light fixture of light in two lens; Light efficiency is soft not dazzling, thereby very is fit to normal lighting.

Above-mentioned PC substrate 1, first crystalline lens 2 and second crystalline lens 3 is all rounded and all be provided with one heart up and down; The quantity of the LED lamp 12 and the light trough 22 that is complementary with it specifically is the 3-10 group, and the LED lamp 12 and the light trough 22 that is complementary with it are that the center is arranged and circularized with the center of circle of first crystalline lens 2.

In addition, the utility model scheme is not limited to above-mentioned PC substrate 1, first crystalline lens 2 and all rounded unique shape of second crystalline lens 3, and PC substrate 1, first crystalline lens 2 and second crystalline lens 3 can also be square.PC substrate 1, first crystalline lens 2 and second crystalline lens 3 can be that the center arrangement circularizes equally with the square center of first crystalline lens 2, also can be arranged in square accordingly.
