Abstract
The utility model discloses a fronting light source focusing illuminating device which comprises a shell, an LED light source and a heat radiating device, wherein the front end of the shell is provided with a concave mirror oriented reflection cup; the heat radiating device is arranged in front of the concave mirror oriented reflection cup; and the LED light source is arranged at one side of the heat radiating device close to the concave mirror oriented reflection cup. Because the heat radiating device and the LED lamp are arranged in front of the shell and not arranged in the shell, the heat radiating effect of the illuminating device is good.
Description
Technical field
The utility model relates to the lighting of the preposition focus reflection of a kind of a fitting structure part, especially light source.
Background technology
Traditional LED lighting device comprises shell, reflector and led light source, described reflector is installed in the leading section of product casing, led light source is located in the reflector, during the work of LED lighting device, can produce a large amount of heats, these heats can only pass through mount pad, shell heat radiation, and these parts interface when connecting all is the interface of high thermal resistance, greatly influenced the conduction of heat, therefore, radiating effect is bad.The great power LED of particularly current just a large amount of light level of using though luminous efficiency has been done large increase in recent years, for single LEDs, does not still reach the actual requirement of illumination.Therefore, the used LED number of existing products in markets is uneven, because LED number increases, the light fixture heat radiation has just become technological difficulties with luminous intensity distribution.
The utility model content
The purpose of this utility model is for a kind of 3 high-power preposition LED focus reflection lighting devices are provided, utilize structure of the present utility model, the lighting device good heat dissipation effect, pass through reflecting and light distributing, brightness can reach and enough reach actual requirement, and can adapt to the LED luminous efficiency and improve, product is selected for use more extensive to LED.
For achieving the above object, a kind of front located light source focus illumination device comprises shell, reflector, 3 high-power LED light sources and heat abstractor; Described shell front end is provided with the concave mirror reflector; Described heat abstractor is located at towards the place ahead of concave mirror reflector; Described led light source is located at the side of heat abstractor towards the concave mirror reflector.
The illumination that said structure, led light source send is mapped on the concave mirror reflector, then, and by light being reflected towards the concave mirror reflector.The heat that led light source produced spreads out of by heat abstractor, and also can be directly transferred in the air, therefore, and good heat dissipation effect.Structure of the present utility model, by adjusting led light source and can adjusting focal beam spot towards the distance of concave mirror reflector, because heat abstractor and led light source all are arranged on the place ahead of shell, therefore, it is convenient to adjust.
As improvement, described heat abstractor exposes in air.This structure after the heat that led light source produces is transmitted on the heat abstractor, can directly conduct heat in the air simultaneously, has further improved radiating effect.
As improvement, be connected with heat pipe between described heat abstractor and the shell.Heat pipe is set, and the part heat on the heat abstractor can be transmitted on the shell, has increased area of dissipation, has further improved radiating effect.
As improvement, described led light source comprises three, and three LEDs light sources are arranged on the same circumference.
As improvement, the angle between the adjacent LED light source is between 115 ° to 125 °.(different product requires to allow 10 ° of errors)

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
Front located light source focus illumination device as shown in Figure 1 to Figure 3 comprises shell 1, concave mirror reflector 2, led light source 3 and heat abstractor 6.
Structure of the present utility model, to shown in Figure 6, the light 4 that led light source 3 sends shines on concave mirror reflector 2 as Fig. 4, then, forms reverberation 5 by towards concave mirror reflector 2 light being reflected.On the heat heat loss through conduction device 6 that led light source 3 is produced, heat abstractor 6 spreads out of heat by dual mode, a kind of is directly to conduct heat in the air, another kind is that the heat on the heat abstractor 6 is transmitted on the shell 1 by heat pipe, so just increase area of dissipation, and the heat of led light source also can be directly transferred in the air, therefore, and good heat dissipation effect.Structure of the present utility model can be adjusted focal beam spot by adjusting led light source 3 with the distance of concave mirror reflector 2, and as shown in Figure 4 and Figure 5, the light that shot-light and Down lamp emit is certain angle light, and as shown in Figure 6, the light that lantern emits is directional light; Because heat abstractor and led light source all are arranged on the place ahead of shell, therefore, it is convenient to adjust.Three LEDs of the present utility model and depositing than two or four or plurality of LEDs more have superiority, and other three LEDs are best light distribution structures.
The utility model is simple in structure, light is concentrated also adjustable, the LED rapid heat dissipation of range of angle adjustable, light, can be applicable on the illuminating products such as indoor and outdoor shot-light, overlength distance lantern.
