Embodiment Construction

[0017] The embodiments will be described in detail below in conjunction with the accompanying drawings.

[0018] See attached figure 1 And attached figure 2 , a LED traffic signal light lens mask 10, including Fresnel lenses 1 of different shapes and lens holders 2, the Fresnel lenses 1 of different shapes are spliced ​​and combined to form an arrow shape, and the Fresnel lenses 1 are fixed on the On the lens holder 2; the Fresnel lenses 1 of different shapes are four rhombic Fresnel lenses 11 and two rectangular Fresnel lenses 12.

[0019] Further, for the four rhombic Fresnel lenses 11, two pattern faces are upward and two pattern faces are downward.

[0020] Further, the surface of the pattern of the lens mask 10 formed by splicing and combining the four rhombic Fresnel lenses 11 and the two rectangular Fresnel lenses 12 is all upward.

[0021] Further, each Fresnel lens 1 corresponds to an LED module 3, and the LED module 3 realizes various functions required for traff...

Abstract

The invention provides an LED traffic signal lens mask. The LED traffic signal lens mask comprises different shapes of Fresnel lenses and lens brackets. Different shapes of Fresnel lenses are combined to form an arrow shape in a splicing mode. The Fresnel lenses are fixed to the lens brackets. Different shapes of Fresnel lenses are four rhombus Fresnel lenses and two rectangular Fresnel lenses. According to the LED traffic signal lens mask, a plurality of different shapes of Fresnel lenses are combined to form a required collimated light field shape in a splicing mode, and each Fresnel lens corresponds to an LED module. The effect of using a plurality of Fresnel lenses for different light field pattern collimation is better than the effect of using a single Fresnel lens for collimation, and the sharpness of the pattern is greatly improved. Through the splicing combination form, a plurality of Fresnel lenses are used for splicing combination to form different shapes which traffic signals require.

Description

technical field [0001] The invention belongs to the technical field of optical masks, in particular to an LED traffic signal lamp lens mask. Background technique [0002] As a new light-emitting device with stable luminous performance, high photoelectric conversion efficiency and strong environmental tolerance, light-emitting diodes have been widely used in the field of traffic lights. In this field, two methods are usually used to realize traffic signal patterns with specific indication functions: the first one is to use multiple in-line low-power LED lamp beads to arrange traffic signal patterns; the second one is to use high-power LED , Fresnel lens and circular traffic signal pattern of pillow-shaped fly-eye lens array for light shielding to realize specific traffic indication pattern. Existing high-power LED traffic lights usually use a single-shaped Fresnel lens to collimate the large-angle outgoing beams from seven high-power LEDs. However, the peak brightness of th...
