Abstract

An LED illumination lamp bar comprises a substrate (1) and LED chips (3). Small holes (2) penetrating through the substrate (1) are formed in the substrate (1), the LED chips (3) are located in the small holes (2), and a copper-coating wire (4) connected between the LED chips (3) is arranged on the substrate (1). The small holes (2) penetrating through the substrate (1) are formed in the substrate (1), the LED chips (3) are located in the small holes (2), and the LED chips (3) can effectively light in the vertical direction of the substrate (1). The LED illumination lamp bar solves the problems in an LED lamp substrate in the prior art that lighting efficiency is influenced due to the fact that light transmittance is not high. Meanwhile, the LED illumination lamp bar improves the cooling effect and solves the problem in the prior art that the service life of the LED lamp is shortened due to the fact that heat is over concentrated, so that reliability of the LED lamp is improved, and the service life of the LED lamp is prolonged.

Description

A kind of LED illuminating lamp bar

Technical field

The utility model relates to a kind of LED lamp, particularly a kind of LED illuminating lamp bar.

Background technology

Due to plurality of advantages such as LED light fixture have energy-saving and environmental protection, stable performance, volume is little, the life-span is long, in a lot of fields, be widely used; LED lamp is more and more extensive in the application of lighting field, at lighting field, plays an important role.

In existing LED lamp, substrate adopts the limited transparent material of light transmittance, and because the light that the not high LED of the making wafer of substrate light transmittance sends can not all outwards be exported through substrate, this makes the light extraction efficiency of LED lamp lower; And the heat that this structure can not produce LED lamp spread out of rapidly, this heat that LED wafer is produced is too concentrated, and then causes the reliability of LED lamp to be linear rule declining, shortened the service life of LED lamp.

Utility model content

Not high in order to overcome the light transmittance that existing LED lamp substrate exists, heat is too concentrated the problem of the LED lamp shortening in service life causing, the utility model provides a kind of and can improve LED lamp light emission rate and improve the scheme of radiating effect, thereby has improved reliability and the service life of LED lamp.

In order to achieve the above object, the technical solution of the utility model is as follows:

A LED illuminating lamp bar, comprises substrate 1 and LED wafer 3, it is characterized in that substrate 1 is provided with the aperture 2 that penetrates substrate 1, and LED wafer 3 is positioned at aperture 2, and substrate 1 is provided with to be connected in and covers copper cash 4 between each LED wafer 3.LED wafer 3 of the present utility model can double-side, there is no blocking of substrate 1, and its luminous efficiency obviously improves, and further can improve radiating effect, improves life of product.

During concrete enforcement, on LED wafer 3, be coated with fluorescent material 5.

During concrete enforcement, be provided with transparent heat radiation coating 6, heat radiation coating 6 is wrapped in substrate 1 and LED wafer 3 peripheries.

During concrete enforcement, substrate 1 have one and more than, linearly shape or U-shaped, or spirality.The utility model can adopt linearly shape or U-shaped according to the needs of luminous intensity distribution and design, or spirality, improves luminous lighting degree, reliability and the service life of further having improved LED lamp.

The beneficial effects of the utility model are: the utility model substrate is provided with the aperture that penetrates substrate, LED wafer is positioned at aperture, LED wafer up and down all can be effectively luminous substrate, do not overcome light transmittance that the LED lamp substrate of prior art exists high and affect the problem of luminous efficiency, simultaneously, it has improved radiating effect, and the heat that overcomes prior art is too concentrated and problem that the LED lamp that causes shortens service life, thus reliability and the service life of having improved LED lamp.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, utility model is further illustrated.

Fig. 1 is the Facad structure schematic diagram of the utility model embodiment LED illuminating lamp bar.

Fig. 2 is partial cross section's structural representation of the utility model embodiment LED illuminating lamp bar.

Fig. 3 is the side structure schematic diagram of the utility model embodiment LED illuminating lamp bar.

In figure: 1, substrate 2, aperture 3, LED wafer 4, cover copper cash 5, fluorescent material 6, heat radiation coating.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is done in further non-limiting description: Fig. 1, Fig. 2 and Fig. 3, the linearly shape LED illuminating lamp bar of take is example, comprise substrate 1 and LED wafer 3, substrate 1 is provided with the aperture 2 that penetrates substrate 1, aperture 2 is slightly larger than the profile of LED wafer 3, LED wafer 3 is positioned at aperture 2, substrate 1 is provided with to be connected in and covers copper cash 4 between each LED wafer 3, on LED wafer 3, be coated with fluorescent material 5, be provided with transparent heat radiation coating 6, heat radiation coating 6 covers the upper and lower of base 1 and wraps up LED wafer 3 and the periphery of fluorescent material 5.

Substrate 1 of the present utility model can have one and more than, linearly shape or U-shaped, or spirality, does not just make marginal data at this.

The utility model substrate 1 is provided with the aperture 2 that penetrates substrate 1, LED wafer 3 is positioned at aperture 2, LED wafer 3 up and down all can be effectively luminous substrate 1, do not overcome light transmittance that the LED lamp substrate of prior art exists high and affect the problem of luminous efficiency, simultaneously, it has improved radiating effect, and the heat that overcomes prior art is too concentrated and problem that the LED lamp that causes shortens service life, thus reliability and the service life of having improved LED lamp.

Finally, it is also to be noted that, what more than enumerate is only specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, can also have many distortion.All distortion that those of ordinary skill in the art can directly derive or associate from disclosed content of the present utility model, all should think protection domain of the present utility model.
