The utility model content
Technical problem to be solved in the utility model is the defective that overcomes prior art, and a kind of good heat dissipation effect, LED underground lamp easy for installation are provided.
The utility model is achieved through the following technical solutions:
A kind of LED underground lamp, comprise lamp body and be installed on the luminescence component that comprises LED in the lamp body, at the lamp body front end transparent glass and light cover are installed, in lamp body, be provided with the step that has difference in height each other, step is divided into lamp body two cavitys that hold luminescence component and electric drive parts respectively, luminescence component is installed on each step surface, is distributed with fin in the step surface bottom.
As improvement to such scheme, between lamp body front end face and transparent glass, be lined with waterproof apron, between step surface, lamp body and the transparent glass seal chamber.
Above-mentioned luminescence component comprises the aluminium base of fixed L ED, and aluminium base directly is close on the step surface, is provided with optical lens in LED the place ahead, and optical lens is fixed on the aluminium base.
As further improvement of these options, be provided with air admission hole in lamp body bottom, the lamp body end face be provided with the step lower cavity together with venthole, the venthole height is higher than the lamp body end face, light cover is covered in the venthole top.Light cover is fixed on the lamp body by screw, is provided with the screw-threaded counterbore that is directed downwards in the light cover bottom surface, and screw passes lamp body from bottom to top and is fixed in the screw-threaded counterbore.
As the further improvement to such scheme, above-mentioned electric drive parts pass the step bottom with the lead that is connected of luminescence component, and interspersed lead place is provided with the waterproof plug at step.The electric drive parts that adopted are waterproof sealing structure, are fixed in the lamp body inner bottom part.
As further improving, described lamp body is fixed in one and directly is embedded in the underground built-in fitting again, and lamp body is fixed in the built-in fitting by screw.
Prior art is compared relatively, the utlity model has following advantage:
1. lamp body is divided into two-layerly, top is divided into hermetically-sealed construction, and the lower part is provided with fin, and guaranteed that by air admission hole and venthole inner air forms strong convection current with outside, heat-sinking capability is strong, bears power level increase at double, and the LED application of high-power illuminations such as trees and exterior wall is become a reality;
2. use installation to be kept to and have only fixed lamp body one procedure, make light cover waterproof control change factory's assembling control into, avoid waterproof human accident to occur by the electrician is installed by two procedures;
3. light cover does not expose screw terminal, helps outward appearance.
Description of drawings
Accompanying drawing 1 is the utility model embodiment decomposing state structural representation;
Accompanying drawing 3 is another vertical section structure schematic diagram of present embodiment
The specific embodiment
Understanding for the ease of those skilled in the art describes in further detail the utility model below in conjunction with the drawings and specific embodiments.
Shown in accompanying drawing 1～3, the LED underground lamp that this programme disclosed comprises built-in fitting 8, is fixed with lamp body 1 by screw in built-in fitting 8, and luminescence component 2 and electric drive parts 9 are installed in the lamp body 1, at lamp body 1 front end transparent glass 3 and light cover 4 is installed.Built-in fitting 8 is embedded in the ground, is used to isolate lamp body 1 and extraneous earth.Be provided with the step 11 that has difference in height each other in lamp body 1, step 11 is divided into two cavitys that hold luminescence component 2 and electric drive parts 9 respectively with lamp body 1, and luminescence component 2 is installed on each step surface, and is distributed with fin 15 in the step surface bottom.The assembly 2 of giving out light comprises the aluminium base 21 of LED22 and fixed L ED22, and aluminium base 21 directly is close on the step surface, in order to have good translucent effect, is provided with optical lens 23 in LED22 the place ahead, and optical lens 23 is fixed on the aluminium base 21 equally.
Between lamp body 1 front end face and transparent glass 3, be lined with waterproof apron 6, be seal chamber between step surface, lamp body 1 and the transparent glass 3, simultaneously, electric drive parts 9 pass step 11 bottoms with the lead that is connected of luminescence component 2,11 interspersed lead places are provided with waterproof plug 7 at step, and anti-sealing enters step 11 tops.And electric drive parts 9 are waterproof sealing structure also, are fixed in lamp body 1 inner bottom part.
