Abstract
The utility model belongs to lighting field, and relates to a spot lamp, in particular to an MR16 spot lamp. The spot lamp comprises a lamp adapter, an aluminum outer casing for heat radiating, as well as LED light sources, an LED drive power supply and an optical lens, which are placed in an accommodating space formed by the lamp adapter and the aluminum outer casing; the aluminum outer casing is in the shape of a bowl; the optical lens is fixed at the larger end of the aluminum outer casing; the LED light sources are fixed in the aluminum outer casing through an aluminum circuit board; the LED light sources are fixed with the aluminum circuit board in a welding manner; a plurality of sinking grooves are symmetrically arranged along the top edge of the bowl opening of the aluminum outer casing; and a plurality of heat dissipation through-holes are formed in the sinking grooves. The device is applied to a radiating structure of the MR16 spot lamp.
Description
Technical field
The utility model belongs to lighting field, relates to a kind of shot-light, is specifically related to a kind of MR16 shot-light take LED as light source.
Background technology
Common MR16 shot-light, comprise bulb socket, LED light source, LED driving power, optical lens and the aluminium shell that is used for heat radiation, described LED light source, LED driving power and optical lens are placed in the accommodation space of described bulb socket and described aluminium shell composition.LED light source generally adopts several LED lamps to realize, described LED driving power adopts the Switching Power Supply power supply, and described aluminium shell is bowl-shape (as shown in Figure 1), and optical lens is fixed on the big opening end of aluminium shell, and optical lens is PMMA or PC material.Described LED light source is fixed on the inside of aluminium shell by aluminum base circuit board, be welded and fixed between LED light source and aluminum base circuit board.
In above-mentioned parts, as shown in Figure 1, aluminium shell is a plurality of louvres 101 for heat radiation evenly is provided with, and this slotting structure of wearing is single, and radiating effect is good not, causes life of product not long.
The utility model content
Technical problem to be solved in the utility model is, a kind of shot-light is provided, and its aluminium shell is improved, and increases area of dissipation, and forms convection channel more smoothly, the heat loss through convection better effects if, thus extend life of product.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is, a kind of shot-light, the aluminium shell that comprises bulb socket and be used for dispelling the heat, and interior LED light source, LED driving power and the optical lens of accommodation space that is placed in described bulb socket and described aluminium shell composition, described aluminium shell is bowl-shape, described optical lens is fixed on the big opening end of aluminium shell, described LED light source is fixed on the inside of aluminium shell by aluminum base circuit board, be welded and fixed between LED light source and aluminum base circuit board.Wherein, described aluminium shell is provided with several heat radiation through holes along being provided with symmetrically several deep gouges along side on the rim of a bowl in described deep gouge.
Further, described aluminium shell is along evenly being provided with 6 deep gouges along side on the rim of a bowl.
Further, be provided with 3 heat radiation through holes in described deep gouge.
Further, the bottom centre of described aluminium shell is provided with the square through hole that aluminum base circuit board is installed.
The utility model is by adopting such scheme, utilize the thermal conductive resin of aluminium shell, be transmitted on the cup and bowl wall of aluminium shell with the heat that sends during directly with the work of LED lamp source at the bottom of cup, and dispel the heat to air through deep gouge and louvre, the mode of wearing is inserted in this front and back, compared with prior art, have the following advantages:
1, appearance and modeling is novel: six uniform deep gouges visually change to insert and wear the single face shaping of structure;
2, save spillage of material: deep gouge makes as the aluminium shell of radiator lighter, more saves material;
3, by the cooperation of deep gouge and louvre, increased area of dissipation: simple inserting worn structure relatively, and area of dissipation is larger;
4, heat loss through convection is better: deep gouge forms convection channel more smoothly.
Description of drawings
Fig. 1 is the schematic diagram of the aluminium shell of prior art;
Fig. 2 is the overall schematic of embodiment of the present utility model;
Fig. 3 is the isometric front view of the aluminium shell of embodiment of the present utility model;
Fig. 4 is the rear isometric view of the aluminium shell of embodiment of the present utility model.
The specific embodiment
Now with the specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
as a specific embodiment, as Fig. 2-shown in Figure 4, a kind of MR16 shot-light of the present utility model, comprise pin 1, bulb socket 2 and be used for the aluminium shell 3 of heat radiation, and the interior LED light source 4 of accommodation space that is placed in described bulb socket 2 and described aluminium shell 3 compositions, LED driving power (not shown on figure) and optical lens (not shown on figure), described aluminium shell 3 is bowl-shape, described optical lens is fixed on the big opening end of aluminium shell, described LED light source 4 is fixed on the inside of aluminium shell 3 by aluminum base circuit board, be welded and fixed between LED light source 4 and aluminum base circuit board.Wherein, described aluminium shell 3 is provided with 3 heat radiation through holes 311 along being provided with symmetrically 6 deep gouges 31 along side on the rim of a bowl in described deep gouge 31.Certainly, the quantity of the quantity of deep gouge 31 and heat radiation through hole 311 can be customized by customer demand, is not limited to the number of this place statement.The bottom centre of described aluminium shell 3 is provided with the square through hole 32 that aluminum base circuit board is installed.
In sum, the utility model adopts the novel project organization of deep gouge and louvre, has significantly increased area of dissipation, and the thermal diffusivity of aluminium shell of having eliminated prior art is bad so that the impaired factor of shot-light working life has good practicality.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
