Abstract

The utility model provides a spotlight. The spotlight comprises a lamp holder, a heat dissipation body arranged on the lamp holder, a plurality of LED lamps arranged on the lamp holder and a lens arranged above the LED lamps. The heat dissipation body is in the shape of a cup, a cavity is formed in the heat dissipation body, the LED lamps are installed on the lamp holder through the interior of the cavity, and the lens is arranged at an open end of the heat dissipation body and is detachably fixed to the heat dissipation body through a fixing ring. Being detachably fixed through the fixing ring, the lens of the spotlight is convenient to maintain; the spotlight is attractive in appearance, and light of the LED lamps is well gathered through the lens to achieve good luminance.

Description

Shot-light

Technical field

The utility model relates to a kind of lighting device, particularly a kind of shot-light.

Background technology

The LED light fixture assembled by the LED lamp is high because of its luminous efficiency, and power consumption is few, long service life, and security reliability is strong, and caloric value is little, can not produce mercury pollution and start the advantages such as fast, at lighting field, is widely used.Shot-light on existing market generally comprises lamp body, LED lamp and lens, lens are arranged on lamp body in LED lamp top, and lens are to be fixed on lamp body by the mode such as gluing, non-dismountable, when its internal part damages as LED lamp or circuit, take by force repairing apart and usually cause the damage of the parts such as lens or lamp body, be difficult to install again fixing.

The utility model content

The purpose of this utility model is to provide a kind of shot-light, and its lens are fixed on radiator by retainer ring, are beneficial to dismounting, is convenient to safeguard.

For achieving the above object, the utility model provides a kind of shot-light, it comprises: lamp holder, be located at radiator on lamp holder, be located at the several LED lamps on lamp holder and be located at the lens of LED lamp top, radiator is cup-shaped, be formed with cavity in it, several LED lamps are arranged on lamp holder in this cavity, and lens are placed in the radiator open end, by retainer ring, detachably fix on radiator.

Described lamp holder is provided with circuit board, and several LED lamps are installed and are electrically connected on this circuit board.

Described radiator open end circumference is provided with annular screens, on the radiator circumference of this annular screens top, also is concaved with fixed part, and the lens correspondence is placed in annular screens, and retainer ring coordinates and is fastened in fixed part, thereby lens are fixed on radiator.

Described radiator is the fin radiator, and fin is evenly distributed on its circumference and extends to surrounding.

Described radiator is adopted and is made of aluminum or copper.

Described retainer ring is the annulus with opening, and its diameter is greater than the diameter of radiator openend.

Described lens are simultaneously plane, and another side convexes with the transmittance section of corresponding LED lamp.

The transmittance section of described lens is transparence.

The beneficial effects of the utility model: shot-light of the present utility model, its lens are undertaken dismantled and assembled fixing by retainer ring, are convenient to safeguard, and this shot-light good looking appearance, the fine polymerization of the light by the LED lamp of scioptics, reach preferably illuminance.

In order further to understand feature of the present utility model and technology contents, refer to following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only provide with reference to and the explanation use, not be used for the utility model is limited.

The accompanying drawing explanation

Below in conjunction with accompanying drawing, by the specific embodiment of the present utility model is described in detail, will make the technical solution of the utility model and other beneficial effect apparent.

The decomposed structural representation that Fig. 1 is the utility model shot-light;

The combining structure schematic diagram that Fig. 2 is Fig. 1.

The specific embodiment

Technological means and the effect thereof for further setting forth the utility model, taked, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.

As shown in Figure 1-2, shot-light of the present utility model, comprise: lamp holder 1, be located at radiator 2 on lamp holder 1, be located at the several LED lamps 3 on lamp holder 1 and be located at the lens 4 of LED lamp 3 tops, lens 4 are placed in radiator 2 open end, by retainer ring 5, detachably fix on radiator 2.

Described lamp holder 1 is provided with circuit board 6, and several LED lamps 3 are installed and are electrically connected on this circuit board 6.Radiator 2 is cup-shaped, adopts and is made of aluminum or copper, and it can be the fin radiator, and fin is evenly distributed on its circumference and extends to surrounding, is formed with cavity in it, and several LED lamps 3 and circuit board 6 are arranged on lamp holder 1 in this cavity.Described radiator 2 open end circumference are provided with annular screens 21, also be concaved with fixed part 22 on radiator 2 circumference of these annular screens 21 tops, lens 4 correspondences are placed in

annular screens

21,5 cooperations of retainer ring are fastened in fixed part 22, thereby lens 4 are fixed on radiator 2, by setting firmly of these 5 pairs of lens 4 of retainer ring, be convenient to the dismounting of lens 4, when LED lamp 3 or circuit board 6 damage, can, by these lens 4 are pulled down and safeguarded, after completing, again lens 4 be installed by retainer ring 5.

Described retainer ring 5 is for having the annulus of opening, and its diameter is greater than the diameter of radiator 2 openends, thereby makes this retainer ring 5 have certain folding elasticity, so that it firmly is fastened in the fixed part 22 of radiator 2.Described lens 4 one sides are plane, and another side convexes with the transmittance section 41 of corresponding LED lamp 3.Described transmittance section 41 is transparence, and lens 4 other parts around it are the frosted shape, in the middle of this transmittance section 41, is formed with recess, and to locate accommodating LED lamp 3, and the light that LED lamp 3 is sent carries out the effects such as optically focused.These lens 4 are gone back the effect that cocoa serves as protecgulum, thereby LED lamp 3 is covered, and play a protective role, and then make shot-light integral body more attractive in appearance.

In sum, shot-light of the present utility model, its lens are undertaken dismantled and assembled fixing by retainer ring, are convenient to safeguard, and this shot-light good looking appearance, the fine polymerization of the light by the LED lamp of scioptics, reach preferably illuminance.

The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection domain of the utility model claim.
