Abstract
The invention discloses an LED (Light Emitting Diode) lamp bar which at least comprises two LED lamps, a substrate and a light diffusion structure, wherein the LED lamps are fixed on the substrate, and the light diffusion structure is positioned right above the LED lamps. The LED lamp bar disclosed by the invention has the advantages that the light emitting angle is large, and the light emitting utilization rate is high.
Description
Technical field
The present invention relates to a kind of LED (Light-Emitting Diode, light emitting diode) technology, particularly a kind of LED lamp bar.
Background technology
LED is a kind of solid-state semiconductor devices that electric energy can be converted into visible light, and it can directly be converted into light to electricity, but the lighting angle of existing LED lamp bar is little, and luminous utilization rate is low.
Summary of the invention
Technical problem to be solved by this invention provides a kind of LED lamp bar, the high and luminous utilization rate height of its lighting angle.
For solveing the technical problem, the invention provides a kind of LED lamp bar, it is characterized in that it comprises two LED lamps, substrate, astigmatic structure at least, the LED lamp is fixed on the substrate, astigmatic structure be positioned at the LED lamp directly over.
Preferably, described astigmatic structure is shaped as triangle.
Preferably, described astigmatic structure is shaped as circle.
Positive progressive effect of the present invention is: the big and luminous utilization rate height of LED lamp bar lighting angle of the present invention.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the structural representation of another embodiment of the present invention.
The specific embodiment
Lift a preferred embodiment below, and come the clearer the present invention that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, LED lamp bar of the present invention comprises two LED lamps 1, substrate 2, leg-of-mutton astigmatic structure 3 at least, LED lamp 1 is fixed on the substrate 2, leg-of-mutton astigmatic structure 3 is positioned at the top of LED lamp 1, the light that LED lamp 1 sends can spread angle after by leg-of-mutton astigmatic structure 3 and penetrate, the light that last LED lamp 1 sends is more even, luminous utilization rate height.
As shown in Figure 2, this embodiment and first embodiment are basic identical, and its main difference point is: circular astigmatic structure 4 replaces leg-of-mutton astigmatic structure 3, and the effect of this embodiment and the effect of first embodiment are basic identical.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these embodiments.Therefore, protection scope of the present invention is limited by appended claims.
