Abstract

The utility model discloses a light board for LED spotlights, which comprises a substrate and a plurality of LED units arranged on the substrate, each LED unit comprises a plurality of LED chips, and the LED units are equidistantly distributed along a certain circumference with the center of the substrate as the center of a circle on the substrate. The light board for LED spotlights adopts a plurality of low-power LEDs to centrally distribute to form an LED unit replacing a single high-power LED, the LED units are equiangularly distributed on a circumference of the substrate, and can substitute for the optical distribution requirement of the high-power LEDs, so that high luminous efficiency can be achieved with low cost, moreover, the arrangement mode can perfectly ensure that the appearance of the lens can better meet the aesthetic requirement of consumers, and therefore the light board is more attractive.

Description

The lamp plate that is used for the LED shot-light

Technical field

The utility model relates to the LED technical field, relates more specifically to a kind of lamp plate for the LED shot-light.

Background technology

At present, led light source just progressively replaces conventional light source as the green energy conservation light source at lighting field.Simultaneously, the LED shot-light also progressively replaces traditional shot-light.And now on the market shot-light adopts great power LED as light source more, or low power LED lamp pearl carries out cellular arranging.For the LED shot-light, adopt its luminous point of great power LED cost few and attractive in appearance high, although adopt many low-power LED costs lower, complicated but luminous point is many, seem in appearance plain.Therefore, be necessary to provide a kind of lamp plate of high light effect and aesthetic of can realizing at lower cost to address the aforementioned drawbacks.

The utility model content

The purpose of this utility model provides a kind of have low cost, high light efficiency and the lamp plate that is used for the LED shot-light attractive in appearance.

To achieve these goals, the technical solution adopted in the utility model is: a kind of lamp plate for the LED shot-light is provided, it comprises substrate and is arranged at a plurality of LED unit on the substrate, each described LED unit is comprised of a plurality of led chips, described a plurality of LED unit on substrate along a certain circumference as the center of circle equidistantly distributes take the center of described substrate.

Its further technical scheme is: each described LED unit forms square structure by four led chips.

Its further technical scheme is: the quantity of described LED unit is no less than three.

Compared with prior art, the lamp plate that is used for the LED shot-light that the utility model provides adopts a plurality of low-power LEDs to concentrate LED unit of distribution formation to replace single great power LED, arrange in the mode of a circumference spaced at equal angles around of substrate in a plurality of LED unit, the optics light distribution requirements that can replace great power LED, thereby realize high light efficiency with low cost, and this arrangement mode can make the lens outward appearance more meet consumer's esthetic requirement well, has better aesthetic property.

By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
