Description

LED floodlight

Technical field

A kind of illuminator is the utility model is related to, more particularly to a kind of LED floodlight.

Background technology

Floodlight, be it is a kind of can to all the winds uniform irradiation spot light, what floodlight was sent is highly diffuse, nothing The light in direction rather than clear-cut light beam：Floodlight does not have electrode, is mutually tied with fluorescence discharge principle by electromagnetic induction principle Close and light, floodlight uses LED lighting, and luminescent material is used as by the use of solid Semi separation chip.LED floodlights at present Lamp is widely used in fields such as hotel's exterior wall, factory's field night scene, gardens brightening, interior decorations.

Such as " a kind of floodlight " is disclosed in the Chinese utility model patent that notification number is CN202561494U, including it is upper Lid, under be covered on floodlight lamp module between lower cover, it is general in use because the power of general floodlight is larger Light lamp module can produce substantial amounts of heat, and these heats can only be distributed by upper lid with lower cover, after long-time use easily Cause whole light fixture to be heated too high and damage, radiating fin can be typically provided with light fixture to improve heat dispersion, and it is existing The set-up mode of radiating fin effect on the thermal diffusivity for improving light fixture is unsatisfactory.

Utility model content

The purpose of this utility model is to provide a kind of preferable LED floodlight of radiating effect.

Above-mentioned technical purpose of the present utility model technical scheme is that：

A kind of LED floodlight, including protecgulum, the bonnet that is connected with protecgulum and the LED light source module covered after being fixed on, The bonnet includes being used for the first radiating wall for installing LED light source module, and the first radiating wall is departing from LED light source module Radiating subassembly is provided with surface, the radiating subassembly includes some spaced first radiating fins and some intervals are set The second radiating fin put, some first radiating fins and some second radiating fins apart from one another by and be arranged in parallel；Wherein One radiating fin includes the curved main radiating part of outline, and forward projection of second radiating fin on main radiating part falls completely Enter in the outline of main radiating part.

By using above-mentioned technical proposal, the heat overwhelming majority can be delivered to the first radiating as produced by LED light source module On wall, heat is distributed using the radiating subassembly being arranged on the first radiating wall, wherein the first radiating fin is as main Thermal component is set simultaneously is arranged to arc increasing heat radiation area by its outline, and the be spaced between two first radiating fins Two radiating fins are set as auxiliary heat dissipation part, and both, which combine, improves radiating effect, and its area of dissipation is reduced and made The heat-dissipating space that top is vacateed in the outline of the main radiating part of the first radiating fin must be projected in, is ensured in two first radiating fins Between space in air can smooth outflow, do not influenceed air flow by the setting of the second radiating fin, and then pole Good radiating effect.

Preferably, the bonnet also include from first radiating wall on along outward-dipping setting second radiate wall, First radiating fin also includes the secondary radiating part with main radiating part integrally connected, and the secondary radiating part is arranged on the second radiating On wall.

By using above-mentioned technical proposal, secondary radiating part further increases the area of dissipation of the first radiating fin, enters one Step improves the radiating effect of light fixture.

By using above-mentioned technical proposal, because floodlight is vertically-mounted, the first radiating fin is kept and floodlight Installation direction it is identical, heat can typically rise, and institute's shape between two the first adjacent radiating fins in heat uphill process Into heat dissipation channel be similarly and be vertically arranged so that heat can be smoothly passed over more, avoid due to the first radiating fin its His setting direction causes the situation that heat is blocked, further improving radiating effect.

Preferably, the bonnet also includes setting radiating wall both sides and the curved extension of outline, the expansion Exhibition portion offers arc groove, and separator sheets are provided with the arc groove.

By using above-mentioned technical proposal, the whole width for widening floodlight of setting of extension, and then improve illumination Projected area, and extension can equally play radiating effect；Secondly outline is arranged to arc and increases area of dissipation, exists in addition The arc groove opened up in extension can reduce material cost and overall weight, in addition separator sheets setting in arc groove Put the effect as reinforcement, will in the case where reducing weight proof strength.

As electedly, the LED floodlight also includes reflector, and the reflector includes some diffusions being obliquely installed Plate, light-transmitting opening is offered in the middle part of reflector, some diffuser plates converge at light-transmitting opening, and the LED light source module is placed in light-transmitting opening It is interior.

By using above-mentioned technical proposal, penetrated by the illumination that LED light source module radiates by the light-transmitting opening on reflector Go out, illumination can carry out concentration diffusion under the diffuser plate effect on reflector, improve the scope of illumination.

Preferably, the LED floodlight also includes the transparent glass for being fixed on bonnet, and the protecgulum opens up fenestrate Mouthful, the reflector abuts with transparent glass.

By using above-mentioned technical proposal, illumination can be carried out dodging by transparent glass so that the illumination projected is more To be soft.

Preferably, the bonnet also includes power pack, and the power pack is connected with support frame by pin rotation, The protection cap that the pin can be covered is additionally provided with power pack.

By using above-mentioned technical proposal, support frame can be real using pin as the support fixation of whole floodlight The now rotation connection with power pack and then the conveniently angle of regulation illumination, and being covered pin using protective cover, can avoid pin Follow closely collision exposed and occurring to play a protective role, secondly can also reduce the rust corrosion of pin, improve service life.

Preferably, angle scale is also arranged with the pin, the end set of support frame as described above has to be turned for identifying The mark breach of dynamic angle.

By using above-mentioned technical proposal, support frame can utilize the mark breach pair that end is opened up in rotation process Irradiation angle disk improves angular adjustment precision.

Preferably, the seal groove of annular is offered in the mating surface of the bonnet and protecgulum, the seal groove embeds Provided with sealing ring.

By using above-mentioned technical proposal, being embedded the sealing ring in seal groove can improve after both protecgulum and bonnet coordinate The sealing at edge.

In summary, the utility model has the advantages that：

1st, by the way that LED light source module is arranged on the first radiating wall so that heat is straight as caused by LED light source module Connect and be delivered to the first radiating wall, be incorporated in the first radiating fin set on the first radiating wall and the increase of the second radiating fin The area of dissipation of first radiating wall improves radiating effect, ensures secondly by the area of dissipation for reducing the second radiating fin two the There is larger heat-dissipating space between one radiating fin, improve the mobility of air；

2nd, by the synchronous area for increasing reflector of setting of extension, and then the projection scope of illumination is improved, and simultaneously Area of dissipation further is increased, plays auxiliary heat dissipation effect.
