Detailed ways

The utility model provides an LED lighting lamp and a high-efficiency astigmatism plate thereof, which adopts high-efficiency light-transmitting material of high-transparency film, and is provided with a plurality of right-angled triangular pyramids. The characteristics of being perpendicular to each other, after different times of refraction in the triangular pyramid space, can play the role of diffuser and astigmatism, and can effectively reduce light resistance and energy loss, improve luminous efficiency, and can form a variety of three-dimensional luminous patterns, The brightness is at least 50% higher than that of the light guide plate type flat light of the same wattage, which effectively saves energy consumption. The present utility model will be described in detail below with reference to specific embodiments and accompanying drawings.

As shown in FIG. 1, the LED high-efficiency astigmatism plate 1 provided by the present invention is made of high-transparency film, including a back and a front. The front is provided with a number of right-angled triangular pyramids 2, and the three sides of the right-angled triangular pyramid 2 are perpendicular to each other, And the bottom side is attached to the front side. The right-angled triangular pyramid 2 can be engraved by laser.

The outer periphery of the front surface extends along its own vertical direction to form an enclosure plate 11 , and a transparent mirror surface is fixed on the outer edge of the enclosure plate 11 . Since the front of the LED high-efficiency light diffusing plate 1 is provided with a right-angled triangular pyramid 2, a transparent mirror is used to set it in the cavity enclosed by the enclosure plate 11, which can effectively prevent dust accumulation or damage on the front, and will not affect the transmittance of light. .

The bottom surface of the right-angled triangular pyramid 2 is an equilateral triangle, an isosceles triangle or a scalene triangle, as shown in Fig. 2 , Fig. 3 and Fig. 4 respectively, and the shapes are all intercepting a corner of a cube. Different shapes of the right-angled triangular pyramid 2 can produce apertures of different shapes.

The utility model also provides an LED lighting fixture, which includes the LED high-efficiency astigmatism plate 1 and the LED light strip 30 with the above-mentioned structure. A plurality of lamp beads 31 are arranged on the 30 at intervals, and the bottom surface of the right-angled triangular pyramid 2 is arranged corresponding to the lamp beads 21 . The LED light strip 30 is arranged on the back. Due to the structural characteristics of the right-angled triangular pyramid 2 and the high light transmittance of the high-transparency film, when the light from the lamp beads 31 on the LED light strip 30 is refracted multiple times from the bottom surface upward through the right-angled triangular pyramid 2 , will form a circular or hexagonal aperture, reduce light resistance and energy loss, and can improve the luminous efficiency.

A fixed aperture shape is refracted on the plate 1.

The bottom surface of the right-angled triangular pyramid 2 is correspondingly covered on one or two lamp beads 31 . If the size of the right-angled triangular pyramid 2 is too small, the refraction of the light from the lamp beads 31 through the right-angled triangular pyramid is very small, and the effect of improving the luminous efficiency cannot be achieved, but covering one or two lamp beads 31 can make the light produce sufficient refraction.

A plurality of right-angled triangular pyramids 2 can be arranged in sequence to form a circular, triangular or hexagonal pattern, and can be combined into various shapes according to needs, which can be used for identification or indication of various buildings.

The LED light strip 30 is arranged in a swivel S shape, the light box 3 is provided with a light trough matching the shape of the LED light strip 30 , and the LED light strip 30 is arranged in the light trough. Since the LED light strips 30 are provided with multiple rows, the LED light strips 30 are fixed by means of a light groove, which can effectively prevent the position from shifting.

The utility model adopts the high-efficiency light-transmitting material of high-transparency film, and a plurality of right-angled triangular pyramids are arranged. When the light spot irradiates the right-angled triangular pyramid, due to the characteristic that its three sides are perpendicular to each other, it passes through the triangular pyramid space for different times.
