Abstract

The utility model discloses an LED (light emitting diode) lamp mask, and aims to provide the big-radian LED lamp mask of which the wall thickness is continuously decreased progressively from the top to two ends. The LED lamp mask comprises a mask (1) and a clamping part (2), wherein the radian of the mask (1) is 4.2-6.2; the wall thickness of the mask (1) is decreased progressively from a mask top (4) to two ends; the wall thickness of the mask top (4) is 2.2-2.4mm; the wall thickness of a mask middle part (3) is 1.9-2.1mm; the wall thickness of the clamping part (2) is 1.7-1.8mm; and the height of the cavity of the mask (1) is 40-70mm. According to the LED lamp mask disclosed by the utility model, the ray refraction angle can be improved, the reasonable light distribution of a lamp is guaranteed, and heat generated by a light source is helped to emit.

Description

A kind of LED light fixture face shield

Technical field

The utility model relates to a kind of LED light fixture face shield, in particular, relates to the LED light fixture face shield that a kind of large radian, wall thickness constantly successively decrease toward two ends from mask top.

Background technology

LED is as solid state light emitter of new generation, have the many merits such as long, energy-efficient, environmental protection of life-span, be widely applied to lighting field, but because the led light source exiting surface is that its characteristics of luminescence of a plane is lambertian distribution, if when directly using or continuing to use the luminous intensity distribution way of conventional light source without suitable optical system processing, when human eye is directly seen led light source, can produce discomfort, have serious glare problem, can damage human eye when serious.Therefore, the utility model is designed a kind of LED light fixture face shield, utilizes the difference of face shield wall thickness, obtains different printing opacity and light mixing effect, reaches the purpose that reduces the light fixture dazzle; LED light fixture face shield is large radian, can improve the light refraction angle; Simultaneously, the cavity height of face shield is large, can help to distribute the heat that light source produces.

The utility model content

The utility model is for the deficiency of existing product, the LED light fixture face shield that provides a kind of large radian, wall thickness constantly to successively decrease toward two ends from mask top.

A kind of LED light fixture face shield of the present utility model comprises face shield, retained part, the radian of described face shield is 4.2-6.2, the wall thickness of face shield successively decreases toward two ends from mask top, the wall thickness of mask top is 2.2-2.4mm, the wall thickness at face shield middle part is 1.9-2.1mm, the wall thickness of retained part is 1.7-1.8mm, and the cavity height of described face shield is 40-70mm.

The beneficial effects of the utility model: (1) simple in structure, be easy to make; (2) practical, because the difference of face shield wall thickness obtains different printing opacity and light mixing effect, reduce the light fixture dazzle, guaranteed the reasonable luminous intensity distribution of light fixture; LED light fixture face shield is large radian, can improve the light refraction angle, makes face shield refraction rising angle greater than 180 °; The cavity height of face shield is large, has increased heat-dissipating space, has optimized radiating effect; (3) cost is low.

Description of drawings

Fig. 1 is structural representation of the present utility model; Fig. 2 is left view of the present utility model;

Among the figure: face shield 1, retained part 2, face shield middle part 3, mask top 4.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

In the drawings, a kind of LED light fixture face shield of the present utility model is comprised of face shield 1, retained part 2, face shield middle part 3 and mask top 4.

The radian of described face shield 1 is 5.41, and the wall thickness of face shield 1 successively decreases toward two ends from mask top 4, and the wall thickness of mask top 4 is 2.3mm, and the wall thickness at face shield middle part 3 is 2.0mm, and the wall thickness of retained part 2 is 1.8mm, and the cavity height of described face shield 1 is 45mm.

Because face shield 1 is large radian, radian is 5.41, makes face shield 1 refraction rising angle greater than 180 °, improves the light refraction angle; Face shield 1 wall thickness successively decreases toward two ends from mask top 4, obtains different printing opacity and light mixing effect, reduces the light fixture dazzle, has guaranteed the reasonable luminous intensity distribution of light fixture; The cavity height of face shield 1 is 45mm, has increased heat-dissipating space, has optimized radiating effect.

Claims

1. LED light fixture face shield, comprise face shield (1), retained part (2), it is characterized in that, the radian of described face shield (1) is 4.2-6.2, the wall thickness of face shield (1) successively decreases toward two ends from mask top (4), and the wall thickness of mask top (4) is 2.2-2.4mm, and the wall thickness at face shield middle part (3) is 1.9-2.1mm, the wall thickness of retained part (2) is 1.7-1.8mm, and the cavity height of described face shield (1) is 40-70mm.
