Description

A kind of great power LED floodlight

Technical field

The utility model relates to a kind of lighting device, and definite says, is a kind of great power LED floodlight.

Background technology

In recent years, illuminating LED had had significant progress at cost, aspect of performance, compared with conventional light source, and the LED lighting has weak point long, start-up time in life-span, sound construction, advantage such as energy-conservation, is significant for environmental protection and energy savings.

But because LED is photoelectric device, very low of the conversion ratio that its electric energy is converted into luminous energy, most of energy has been converted to heat, if adopt great power LED then to generate heat more obvious.Height, especially normal appearance the in high-power LED lamp that so the temperature of LED light fixture just can be very because the LED that caloric value causes greatly decays, thus lighting quality influenced.

Summary of the invention

It is a kind of simple in structure that the purpose of the utility model is to provide, the high-power LED (light emitting diode) lighting equipment of good heat dissipation effect.

The utility model adopts following technology to realize:

A kind of great power LED floodlight; Comprise lampshade, bonnet, LED luminescence unit; The electronic devices and components of LED lamp group and be used to the support that connects the lead of external power source and signal and be used for fixing said LED lamp; Said LED luminescence unit is embedded on the lampshade, and the electronic devices and components of said LED lamp group are installed in the sealed cavity body, and the electronic devices and components sealed cavity body of the said LED of being equipped with lamp group is arranged on the bottom of bonnet.

As a kind of improvement of the utility model, heat radiation wing plate is set on the described lampshade surface.

As a kind of improvement of the utility model, said bonnet is conical.

As a kind of improvement of the utility model, the lens of said LED lamp group are an arc.

As a kind of improvement of the utility model, the lens of said LED lamp group adopt high borosilicate manufacturing.

As a kind of improvement of the utility model, said support is a travel(l)ing rest.

The utlity model has following advantage:

In the utility model, LED lamp group directly is embedded on the lampshade, and so the heat of LED luminescence unit generation directly passes on the radiating fin through lampshade; Reduced the heat radiation link like this; Improved radiating efficiency,, the electronic devices and components of LED lamp group are installed in the sealed cavity body in addition; The sealed cavity body that LED lamp group electronic devices and components are installed is arranged on the bottom of bonnet; The heat that the LED lamp gives out is to not influence of control element, makes the extraordinary heat conductivity of this product tool, prolonged the service life of electronic component.

The specific embodiment

Below in conjunction with Figure of description the utility model is further detailed:

A kind of great power LED floodlight as illustrated in figs. 1 and 2 comprises a lampshade 1, and said lampshade 1 is provided with heat radiation wing plate 2, and heat radiation wing plate 2 is an aluminium sheet; It is at lampshade, and on lampshade 1, embedding has LED lamp group 3, the employing of LED lamp group the high borosilicate lens of arc, become rectangular light spot; Have high temperature resistantly, printing opacity is good, and luminous intensity distribution is even, and a bonnet 5 is equipped with in lampshade 1 back; 5 one-tenth one taper shapes of bonnet also are provided with heat radiation wing plate on bonnet 5, strengthened area of dissipation through taper bonnet 5 and heat radiation wing plate.Make that this great power LED floodlight radiating effect is better.

In the utility model, also be provided with a sealed cavity body 7, be used to place LED lamp group electronic devices and components, sealed cavity body 7 is arranged on the bottom of bonnet 5.

The utility model also comprises the support 6 that is used for fixing said high-powered LED lamp, and said support 6 is a travel(l)ing rest.

[0018In the utility model; Said LED lamp group 3 directly is embedded on the lampshade 1, and so the heat of LED luminescence unit 4 generations directly passes on the radiating fin 2 through lampshade 1, has reduced the heat radiation link like this; Improve radiating efficiency, prolonged the service life of LED.

In the utility model; The electronic devices and components of said LED lamp group are installed in the sealed cavity body 7; The sealed cavity body 7 of the said LED of being equipped with lamp group electronic devices and components is arranged on the bottom of bonnet 5; The heat that the LED lamp gives out is to not influence of control element, makes the extraordinary heat conductivity of this product tool, prolonged the service life of electronic component.
