Abstract

The invention discloses a high-power LED illuminating lamp, which comprises a housing cover, a lens, a power supply, a radiator, a PCB (printed circuit board) and a plurality of groups of LED light sources, wherein the power supply and the LED light sources are electrically connected; the PCB is mounted on the radiator; the lens is mounted in a bayonet of the radiator and located below the PCB; the LED light sources comprise a plurality of LED components arranged side by side and mounted on the front side of the PCB; a plurality of reflection boards are also mounted on the radiator; each group of the LED light sources correspond to a reflection board; each reflection board is integrally manufactured through a flat plate, a plurality of anti-glare plates and arc boards which are located on two sides of the flat plate respectively and extend upwards; and each of the anti-glare plates is located between two adjacent LED components. According to the high-power LED illuminating lamp, the light extraction efficiency can be improved, and the dodging effect is achieved, so that discomfort for human bodies is reduced.

Description

High-power LED lighting fixture

Technical field

The present invention relates to a kind of high-power LED lighting fixture, belong to the LED lighting technical field.

Background technology

At present, dazzle refers in the visual field sensation due to the worry, the discomfort that cause much larger than the adaptable illumination of eyes or the performance that blinds.The light source of dazzle is divided into directly, as sunshine, too strong light etc., with indirectly, and reflective as from smooth object surface (express highway pavement or the water surface etc.).The consequence that produces according to dazzle mainly is summed up as three types: uncomfortable type dazzle, Light-adapted dazzle and funeral can the type dazzles.Because LED belongs to spot light, improperly very easily produce dazzle if use, and then have influence on user's physical and mental health.The traditional lighting light fixture adopts circular lampshade mostly, and light uses the zone from LED light source through arriving after penetrating outside circular lampshade, causes thus a large amount of light losings, makes the light fixture whole lighting efficiency reduce.

Summary of the invention

Technical problem to be solved by this invention is the defective that overcomes prior art, provides a kind of and can improve light extraction efficiency, reaches even light effect, thereby reduces the high-power LED lighting fixture to the human body sense of discomfort.

in order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of high-power LED lighting fixture, comprise cap, lens, power supply, radiator, pcb board and many group LED light sources, power supply is electrically connected to LED light source, pcb board is arranged on radiator, lens are installed in the radiator bayonet socket, and be positioned at below pcb board, LED light source is comprised of a plurality of LED assemblies that are arranged side by side, LED light source is arranged on the front of pcb board, a plurality of reflectors also are installed on described radiator, the corresponding reflector of each group LED light source, reflector is by flat board, a plurality of anti-dazzle tabula rasas and lay respectively at dull and stereotyped both sides and upwardly extending arc plate integral type and make, , a plurality of anti-dazzle tabula rasas lay respectively between adjacent LED assembly.

Further, at the back of cap, suspension ring are installed.

Further, described lens are slab construction.

Adopted technique scheme, the present invention has following beneficial effect:

1, improve light extraction efficiency, reached even light effect.Reflector of the present invention has higher reflectivity in visible wavelength range, make light form diffuse reflection, spot light evenly is converted to area source, thereby reaches even effect of light, increased simultaneously lighting angle, whole light source is more even, soft and full like this.

2, the setting of the anti-dazzle tabula rasa between adjacent LED assembly can reduce this lighting to the dazzle reaction of human body.

3, the LED power of composition LED assembly is very little, can be 0.3 watt, can effectively reduce the cost of product, the color matching luminous intensity distribution is more easily controlled quality, and assembly simultaneously is more flexible, can be according to the application scenario, be designed to different CCT, CRT, shape and size, satisfy different lighting demands.

The specific embodiment

Content of the present invention is easier to be expressly understood in order to make, and the below is according to specific embodiment and by reference to the accompanying drawings, and the present invention is further detailed explanation,

as shown in Fig. 1 ~ 4, a kind of high-power LED lighting fixture, comprise cap 9, lens 7, power supply 11, radiator 2, pcb board 4 and many group LED light sources, power supply 11 is electrically connected to LED light source, pcb board 4 is arranged on radiator 2, lens 7 are installed in radiator 2 bayonet sockets, and be positioned at pcb board 4 belows, LED light source is comprised of a plurality of LED assemblies 3 that are arranged side by side, LED light source is arranged on the front of pcb board 4, a plurality of reflectors 6 also are installed on radiator, the corresponding reflector 6 of each group LED light source, reflector 6 is by dull and stereotyped 6-1, a plurality of anti-dazzle tabula rasa 6-3 and lay respectively at dull and stereotyped 6-1 both sides and upwardly extending arc plate 6-2 integral type is made, a plurality of anti-dazzle tabula rasa 6-3 lay respectively between adjacent LED assembly 3.This structure has improved light extraction efficiency, has reached even light effect.Reflector 6 of the present invention has higher reflectivity in visible wavelength range, make light form diffuse reflection, spot light evenly is converted to area source, thereby reaches even effect of light, increased simultaneously lighting angle, whole light source is more even, soft and full like this.Anti-dazzle tabula rasa 6-3 can reduce this lighting to the dazzle reaction of human body.

For the ease of lifting this lighting, as shown in Figure 4, at the back of cap 9, suspension ring 14 are installed.

For irradiated area is larger, further avoid reflective loss simultaneously, as shown in Figure 3, lens 7 are slab construction.

As shown in Fig. 1 ~ 4, LED light source is two groups, and in Fig. 5 ~ 8, LED light source is four groups.

Above-described specific embodiment; purpose of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the above is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
