Description

A kind of LED projecting lamp lighting device
Technical field
The utility model relates to a kind of lighting device, refers in particular to a kind of LED projecting lamp lighting device.
Background technology
Because LED is energy-conservation, therefore characteristics such as environmental protection and longevity replace the trend that the traditional lighting lamp has become modern development; But there is following problem simultaneously in LED when it uses, as the light decay that causes of the deficiency of dispelling the heat is too fast and service life of greatly reducing LED; Simultaneously since existing production firm often by being welded in a circuit board with LED is same, unified again external power supply, therefore such circuit is if wherein damaging appears in a LED, just representative needs to change the monoblock circuit board, bring the deuce to pay to the user, especially LED is used for heavy construction, as street lamp, when mine lamp or projecting lamp etc. use; Because also there is the reflector lamp phenomenon in the light of LED projection, therefore needs badly now and invent a kind of above-mentioned LED lighting device that solves simultaneously.
The utility model content
The utility model provides a kind of good heat dissipation, and circuit is stable, the uniform LED projecting lamp of light lighting device.
A kind of LED projecting lamp of the utility model lighting device comprises die cast aluminium alloy heat radiation module main body, LED control circuit board, lampshade and diffuser; Described heat radiation module main body top is provided with a plurality of radiating fins, and described heat radiation module lower body part is provided with accepting groove, and described LED control circuit board is fixed in the described accepting groove; Described lampshade is buckled on the described LED control circuit board; Described diffuser is fixed in described accepting groove lower end; Wherein said LED control circuit board is provided with many circuits, is electrically connected a plurality of LED on every circuit; Described lampshade is provided with a plurality of reflectors, and described reflector is the centrum shape, and described reflector is corresponding one by one with described LED.
The utility model LED projecting lamp lighting device by using the die cast aluminium alloy as heat sink material, and is established a plurality of radiating fins on heat radiation module main body top, therefore realizes the radiating effect that high speed is good; Simultaneously the LED control circuit is divided into many circuits, therefore independent control when line failure wherein, can not influence the use of All other routes, guaranteed the circuit stability of entire lighting device; In addition the utility model also is provided with lampshade, is provided with reflector on the lampshade, and the angle of reflector can be adjusted into best angle according to experiment, so the light that LED launches is through after the reflector, and light is more even.
Description of drawings
Accompanying drawing 1 is the side view of the utility model LED projecting lamp;
Accompanying drawing 2 is the upward view of the utility model LED projecting lamp;
Accompanying drawing 3 is the stereogram of the utility model LED projecting lamp
The specific embodiment
In order better to understand the utility model content, the utility model is further specified below in conjunction with accompanying drawing.
See also accompanying drawing 1 and accompanying drawing 2 and accompanying drawing 3, the utility model provides a kind of LED projecting lamp lighting device, comprises die cast aluminium alloy heat radiation module main body 1, LED control circuit board 2, lampshade 3 and diffuser 4.
Described heat radiation module main body 1 is handled through the anode on surface or sandblast anode processing again by the die cast aluminium alloy, can obviously increase radiating effect, described heat radiation module main body 1 top is provided with a plurality of radiating fins 12, described heat radiation module main body 1 bottom is provided with accepting groove 11, accepting groove 11 and radiating fin 12 shared same joint faces; Described LED control circuit board 2 is fixed in the described accepting groove 11, and concrete LED control circuit board 2 is fixed on the joint face; Described lampshade 3 is buckled on the described LED control circuit board 2, and fixes with joint face; Preferably, the cone-shaped reflector 6 that lampshade 3 is provided with above, it can be cone-shaped or circular cone build etc. on four sides, and described reflector 6 is corresponding one by one with described LED.Reflector 6 central authorities offer hole, use for LED and pass, and reflector 6 is provided with the four sides, the axis of each face and the angle of horizontal direction between 25 ° to 45 °, thereby control light just as the time can also avoid total reflection.Preferably, described diffuser 4 is fixed in described accepting groove 11 lower ends;
Preferably, described LED control circuit board 2 is provided with many circuits, is electrically connected a plurality of LED on every circuit; Change many circuits into by the whole piece circuit of inciting somebody to action in the past, and every circuit all is independent control, therefore when wherein arbitrary circuit breaks down, can exert an influence other circuit.
Preferably, heat radiation module main body 1 is handled through the anode on surface or sandblast anode processing again by the die cast aluminium alloy, can obviously increase radiating effect; And being made as many, a plurality of described radiating fins are the heat radiating fin slip that is arranged in parallel along X-direction, each described heat radiating fin slip comprises along Y direction and is a plurality of radiating fins 12 that are arranged in parallel, described radiating fin height is greater than 30mm, along the width of X-direction greater than 50mm, distance between the two adjacent described heat radiating fin slips greater than 3mm less than 8mm, therefore can reach best radiating effect, also can between circuit board and heat radiation module, can increase high hot order wire circuit aluminium base interface glue material simultaneously, be used for heat conduction, the heat conductivility of this Heat Conduction Material is far longer than general heat-conducting cream while can keep long radiating effect.
The utility model LED projecting lamp lighting device by using the die cast aluminium alloy as heat sink material, and is established a plurality of radiating fins on heat radiation module main body top, therefore realizes the radiating effect that high speed is good; In addition the utility model also is provided with lampshade, is provided with reflector on the lampshade, and the angle of reflector can be adjusted into best angle according to experiment, thus the light launched of LED through the emission cup after, light is more even.
Embodiment only is a preferred optimum implementation of the present utility model in sum; unintelligible is that protection domain of the present utility model is limited; for adjustment that does not exceed technical solutions of the utility model and the change that the technical work personnel of this area do according to the utility model, should think and drop in the protection domain of the present utility model.
