Abstract
The utility model discloses an embedded high-power LED shot-light relates to the illumination field, including lamps and lanterns and LED light source, lamps and lanterns are the tube-shape, and the LED light source is installed in lamps and lanterns, the lamps and lanterns overcoat has the radiator of annular tube-shape, and the inlayer of radiator is the pipe with the lamps and lanterns contact, and the outer punching press of pipe goes out the heat radiation fins of multichannel evenly distributed on pipe surface and perpendicular to pipe center pin, connect for the indent arc between the adjacent heat radiation fins. This scheme increases heat radiating area through the length that changes lamps and lanterns, utilizes the annular scattering structure's of perpendicular to axis heat radiation fins reinforcing radiating effect, utilizes the current reduction circuit to make the luminous wafer out of work under the overfrequency state, has prolonged the life of LED lamp, uses 5 LED chips of 3W to increase the luminance of whole LED lamp. The scheme has the advantages of simple structure, lasting brightness and remarkable heat dissipation effect.
Description
Technical field
The utility model relates to lighting field, is specifically related to a kind of embedded great power LED shot-light that is with the radial radiating fin radiator of cylinder.
Background technology
At present; 50 watts of traditional high power jet lamps led light source commonly used is replaced; The LED lighting engineering is as light source technology of new generation; Have characteristics such as energy-saving and environmental protection, the life-span is long, volume is little, can be widely used in fields such as various indications, demonstration, decoration, backlight, general lighting and urban landscape.And the high-power LED shot-light needs good heat dissipation environment, and the fine or not degree direct influence of LED shot-light radiator the operating efficiency and the service life of led light source.The result of use and the brightness of existing 50 watts of high power jet lamps receive the influence of its overall dimensions and volume bigger; Radiator commonly used adopts the mode of arranging a plurality of fins on the plane to dispel the heat, and the characteristics of this radiator are that the big more radiating effect of contact area is good more, but 50 watts of high power jet lamp employings is not the plate armature of using always; But the structure of tubular; In this case, the structure of radiator and volume are just bigger to the influence of LED lamp, just present LED technical merit; Replace the brightness of 50 watts of high power jet lamps of tradition; Do not change full-sized light fixture again, just need a kind ofly both can effectively reduce the heat peak value, can embody the great power LED shot-light of low-carbon (LC) environment and energy-saving efficiency again.
The utility model content
Be the influence of the radiator that reduces great power LED shot-light in the prior art to LED brightness; Increase the radiating effect on the radiator unit are; Improve the brightness of shot-light; The utility model provides a kind of high-power radiator of tubular microflute diffusing structure, has realized both protecting the brightness of great power LED shot-light, has guaranteed the radiating effect of great power LED shot-light again.Concrete scheme is following: a kind of embedded great power LED shot-light of band shape microflute radiator, comprise light fixture and led light source, and said light fixture is a tubular; Led light source is installed in the light fixture; It is characterized in that said light fixture is with the radiator of annular canister shape outward, the internal layer of radiator is the pipe that contacts with light fixture; The skin of pipe stamps out multiple tracks and is evenly distributed on pipe surface and perpendicular to the radiating fin of pipe central shaft, is the connection of indent arc between the said adjacent radiating fin.
Another preferred version of the utility model: the length of said light fixture is 6～9 centimetres.
Another preferred version of the utility model: the mounted LEDs number of chips is 5 in the said led light source.
Another preferred version of the utility model: the power of said led chip is 3W.
Another preferred version of the utility model: said shot-light with fall current circuit and be connected, said fall current circuit be shot-light the required electric current of its led chip calibration power is provided 1/3～1/2.
This programme increases area of dissipation through the length that changes light fixture; Utilization strengthens radiating effect perpendicular to the radiating fin of the circumferential dispersion structure of axis; Current circuit falls in utilization is not operated under the overclocking state luminescent wafer; Prolong the service life of LED lamp, used the brightness of the led chip increasing whole LED lamp of 5 3W.This programme is simple in structure, brightness is lasting and radiating effect is remarkable.
Description of drawings

Current circuit, 5-LED substrate fall in 1-light fixture, 2-radiator, 3-radiating fin, 4-among the figure
The specific embodiment
Like Fig. 1, shown in 2; The utility model comprises light fixture 1 that led light source is installed and the radiator 2 that is used to dispel the heat, and wherein light fixture length is at 6～9 centimetres, and LED substrate 5 is installed in the light fixture; The led chip 6 of 5 3W is distributed on the LED substrate; What the power of led chip can adopt identical wattage also can select different wattages for use, and concrete led chip quantity can be calculated according to effective illuminating area, adjusting the quantity of concrete led chip; Led chip is to adopt the SMT mount technology to be encapsulated on the LED substrate, can reduce the peak value of heat in the LED light fixture so largely.For guaranteeing the service life of led chip; This programme employing is fallen 4 pairs of LED light fixtures of current circuit and is supplied power; Falling current circuit only provides its use electric current of 1/3～1/2 to the led chip of a standard, and promptly the led chip of the 3W led chip that only is equivalent to 1.5～2W uses, just the power of whole shot-light at 8～9W; But the incandescent lamp effect that is equivalent to 50W, and led chip is unlikely to overclocking at work and influences its service life.
It is outer that the radiator 2 of this programme is enclosed within light fixture; Radiator is the pipe shape; Outer surface at pipe utilizes stamping technology evenly to suppress a plurality of radiating fins 3 perpendicular to axis, adopts the arc of indent excessive between fin and the fin, so more helps distributing of light fixture heat; Adopt a plurality of independently fins can increase area of dissipation, the height of each fin is 1～2 centimetre.
