Abstract

The utility model discloses a large-power LED illumination lamp which comprises a shell cover, a lens, a power supply, a heat sink, a PCB and a plurality of sets of LED light sources, wherein the power supply is electrically connected with the LED light sources, the PCB is arranged on the heat sink, the lens is arranged in a clamping port of the heat sink and located below the PCB, and the LED light sources are composed of a plurality of LED assemblies which are arranged side by side. The LED light sources are arranged on the front face of the PCB, the heat sink is further provided with a plurality of reflectors, each set of LED light sources correspond to one reflector, a flat plate, a plurality of anti-dazzle plates and arc plates are integrated to form each reflector, the arc plates are respectively located on two sides of each flat plate and extend upward, and each anti-dazzle plate is located between each two adjacent LED assemblies. The large-power LED illumination lamp can improve optical efficiency, achieves the dodging effect, and therefore reduces discomfort of the human body.

Description

High-power LED lighting fixture

Technical field

The utility model relates to a kind of high-power LED lighting fixture, belongs to the LED lighting technical field.

Background technology

At present, dazzle refers in the visual field sensation owing 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. and indirect, 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, the dazzle of light adaptation type 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 the circular lampshade, causes a large amount of light losings thus, makes the light fixture whole lighting efficiency reduce.

Summary of the invention

Technical problem to be solved in the utility model 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, the technical solution of the utility model 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 with led light source, pcb board is installed on the radiator, lens are installed in the radiator bayonet socket, and be positioned at the pcb board below, led light source is made up of a plurality of LED assemblies that are arranged side by side, led light source is installed in the front of pcb board, a plurality of reflectors also are installed on the 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 the adjacent LED assembly.

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

Further, described lens are slab construction.

Adopt technique scheme, the utlity model has following beneficial effect:

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

2, the setting of the anti-dazzle tabula rasa between the 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 easier control quality of color matching luminous intensity distribution, 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 utility model is easier to be expressly understood in order to make, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below,

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 with led light source, pcb board 4 is installed on the radiator 2, lens 7 are installed in radiator 2 bayonet sockets, and be positioned at pcb board 4 belows, led light source is made up of a plurality of LED assemblies 3 that are arranged side by side, led light source is installed in the front of pcb board 4, a plurality of reflectors 6 also are installed on the 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 and make, a plurality of anti-dazzle tabula rasa 6-3 lay respectively between the adjacent LED assembly 3.This structure has improved light extraction efficiency, has reached even light effect.Reflector 6 of the present utility model has higher reflectivity in visible wavelength range, make light form diffuse reflection, spot light evenly is converted to area source, thereby reaches the effect of even light, increased lighting angle simultaneously, Zheng Ti 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 bigger, further avoid reflective loss simultaneously, as shown in Figure 3, lens 7 are slab construction.
