Abstract

An LED floodlight, the structure of which includes a lamp housing, an LED driver, a circuit board, an LED light source, a lens and a cloth-patterned glass mask. The lens and the cloth-patterned glass mask are combined to form a lamp optical system, which changes the light field distribution of the LED and improves the glare phenomenon. The large-angle light distribution lens broadens the application range of the LED floodlight, and the high-transmittance cloth-patterned glass mask effectively improves the glare phenomenon of the LED floodlight without changing the light output effect of the lens, thereby improving the lighting quality and effect. This type of LED floodlight can not only be used for architectural decorative lighting and billboard lighting with large-area light distribution, but also can be used for main lighting in factories, workshops, power stations, large facilities, venues and other places.

Description

A kind of LED flood light

technical field

The utility model relates to the field of LED lighting, in particular to an LED floodlight.

Background technique

With the rapid development of modern lighting technology, LED, as a new generation of light source, has undergone long-term research and development experiments and market tests. With its obvious advantages such as energy saving, environmental protection, quick response, and long life, it is gradually replacing traditional light sources and becoming the mainstream of modern lighting products.

With the rapid development of LED lighting technology, LED floodlights are widely used in architectural decorative lighting and commercial space lighting. At present, when LED floodlights use high-power LEDs as light sources, the angle of light distribution of lenses used is relatively small, so they cannot be used for architectural decorative lighting that requires large-area light distribution, nor can they be used in factories, workshops, power stations, and large facilities and venues. Main lighting in other places. Moreover, the glare problem generally exists in LED lamps. If it is not solved well, it will affect the lighting effect of LED lamps. For example, Chinese patent CN201110231912.6 "A LED floodlight" is composed of a main body and a bottom bracket. When the light is distributed at a large angle, it is easy to produce glare.

Contents of the invention

In order to expand the market application of LED floodlights and improve the glare phenomenon of LED lamps, the LED floodlight of the utility model adopts a combination of lens and textured glass to form an optical system that changes the light field distribution of LEDs and improves glare. The projecting light fixture composed of the above optical system increases the application range of the light fixture in the lighting field, and improves the lighting quality and effect of the LED light fixture.

The technical scheme of the utility model is:

An LED floodlight, its structure includes a lamp housing, an LED driver, a circuit board, an LED light source, a lens, and a glass cover; the lamp housing includes a power cavity, a light source cavity, and a housing bracket; the LED driver is located cavity; the circuit board is mounted on the bottom of the light source cavity, the LED light source is mounted on the circuit board, the lens cover is above the LED light source, and the glass cover is located above the LED light source and the lens; the glass cover is a fabric Patterned glass mask, the texture direction of which is parallel or perpendicular to the light distribution direction of the lens; the wide angle direction of the lens is 90°~150°, and the light type is a batwing light distribution rectangular spot.

The light transmittance of the textured glass mask is greater than 90%.

A silicone sealing ring is used to seal the cloth-grained glass cover and the lamp housing.

The textured glass cover increases the light-emitting area of a single LED, reduces the glare caused by the high-brightness surface of the LED, thereby improving the glare phenomenon of the lamp; Parallel or vertical, it has little effect on the light distribution of the lens, and does not change the light output effect of the lens.

The utility model has the advantages that: the combination of the lens and the textured glass mask constitutes the optical system of the lamp, which changes the light field distribution of the LED and improves the glare phenomenon. The large-angle light distribution lens broadens the application range of LED floodlights, and the cloth pattern glass cover with high light transmittance can effectively improve the glare phenomenon of LED floodlights without changing the light output effect of the lens, thereby improving the lighting quality and Effect. This kind of LED floodlight can not only be used for architectural decoration lighting and billboard lighting with large-area light distribution, but also for main lighting in factories, workshops, power stations, large facilities, venues and other places.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Example 1

Referring to Fig. 1 and Fig. 2 , an LED floodlight, its structure includes a lamp housing, an LED driver, a circuit board, an LED light source, a lens, and a textured glass cover.

The lamp housing includes a power cavity, a light source cavity and a housing bracket. The housing bracket is connected to the lamp housing and can rotate around the connection point to facilitate adjustment of the projection angle of the floodlight.

The LED driver is located in the power supply cavity; the circuit board is installed at the bottom of the light source cavity, the LED light source is welded on the circuit board, and the lens cover is above the LED light source; the cloth glass cover is located above the LED light source and the lens, and the light transmittance is 92%. The pattern direction is parallel or perpendicular to the light distribution direction of the lens; the wide angle direction of the lens is 90°, and the light type is a batwing light distribution rectangular spot.

The cloth glass cover and the lamp housing are sealed with a silicone sealing ring to achieve dustproof and waterproof effects.

The lens changes the light field distribution of the LED light source to achieve the required light distribution and light pattern. The cloth pattern glass cover can improve the glare phenomenon of the lamp without changing the light output effect of the lens. The combination of the lens and the textured glass cover constitutes the optical system of the lamp, which increases the application range of the lamp in the lighting field and improves the lighting quality and effect of the lamp.
