Abstract
The utility model discloses a high-power LED reflector used for a searchlight, which comprises a reflector body and an LED wafer, and is characterized in that a shallow groove with through holes is formed on the back of the reflector body; the LED wafer is inlaid in the shallow groove; the luminous component of the LED wafer is exposed out of the through hole of the reflector body; the back of the LED wafer clings to a metal heating body; and the metal heating body and the reflector body are in firm connection; the design has the advantages of good heat dissipation effect, long service life, convenient installation, safety, durability and the like and can be widely applied to various portable lighting apparatus.
Description
Technical field
The utility model relates to the reflector that the field of lighting apparatus, particularly searchlight are used.
Background technology
Along with the popularization and application of new type light source light emitting diode (being led light source), its environmental protection, energy-conservation characteristics are rooted in the hearts of the people, and the application technology of led light source more and more is subjected to consumer's attention.At present, in the illuminating products such as tradition torch, searchlight, existing low power led light source is used, but because the restriction of power, can only adopt the many groups of set led light source to be loaded on the interior structure of reflector, cause the Lamp cup body bulky, but luminous intensity be still not enough, general only as floor light, this has also limited the large-scale promotion of led light source on this series products to a certain extent.And the high-power LED light source, because heat dissipation problem fails well to solve, when being applied to illuminating product such as torch, searchlight, often the service life of led light source is not long.Therefore, be necessary the reflecting cup structure of torch, searchlight etc. is improved.
The utility model content
The purpose of this utility model is the weak point that overcomes above-mentioned prior art, proposes the great power LED reflector that a kind of good heat dissipation effect, long service life, searchlight easy for installation, safety durable are used.
The purpose of this utility model is achieved by the following technical solution: the great power LED reflector that searchlight is used, include reflective cup and LED wafer, it is characterized in that the back side of reflective cup is formed with the shallow grooves of band through hole, the LED wafer is embedded in the shallow grooves, the luminous component of LED wafer is exposed to outside the through hole of reflective cup, the back side of LED wafer is glued with the heat dissipation metal body, and heat dissipation metal body and reflective cup are fastenedly connected.Further, for guaranteeing radiating effect, be coated with heat-conducting glue between LED wafer and the heat dissipation metal body.Be fixed L ED wafer, the shape of shallow grooves is corresponding with the outline of LED wafer, and carries out spacing to the LED wafer.And leave the breach that makes things convenient for the wiring of LED wafer to draw on the shallow grooves of reflective cup.
She Ji structure has tangible advantage like this:
1, by improving the syndeton of heat radiation, the heat dispersion of reflector is improved greatly, for the application of high-power LED light source is laid a good foundation.
2, when guaranteeing brightness, the overall dimensions of reflector can be reduced greatly, save the space.
3, connection is installed succinctly conveniently, safe and reliable, long service life.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is the solid partition schematic diagram of utility model.
The specific embodiment
Referring to Fig. 1-Fig. 2, the great power LED reflector of present embodiment is mainly used on torch, the searchlight.Main body is made of reflective cup 1, LED wafer 2, aluminous fin shape radiator 3 and securing member.Special feature is that the central authorities of reflective cup 1 have through hole 11, be formed with shallow grooves 12 on the reflective cup 1 at through hole 11 back sides, LED wafer 2 is embedded in the shallow grooves 12, the thickness of the thickness of shallow grooves 12 and LED wafer 2 is approaching, and the shape of shallow grooves 12 is corresponding with the outline of LED wafer, thereby LED wafer 2 is positioned in the shallow grooves 12, and the luminous component of LED wafer 2 is exposed to outside the through hole 11 of reflective cup 1, what be close to it at the back side of LED wafer 2 is aluminous fin shape radiator 3, preferably be coated with heat-conducting glue between them, simultaneously, aluminous fin shape radiator 3 is anchored on the erection column 13 of shallow grooves 12 sides by securing member, like this, the most of heat that is produced during the luminous work of LED wafer 2 has just passed to aluminous fin shape radiator 3, scatter and disappear behind from reflective cup 1, guarantee that LED wafer 2 works in proper temperature environment.In addition, leaving two place's breach 14 on shallow grooves 12, is to make things convenient for the wiring after LED wafer 2 is fixed to draw.
Certainly, only enumerated a kind of preferred implementation here, the protection category that other is equal to, structure roughly the same all should belong to this patent repeats no more here.
Claims (4)
1. the great power LED reflector used of searchlight, include reflective cup and LED wafer, it is characterized in that: the back side of reflective cup is formed with the shallow grooves of band through hole, the LED wafer is embedded in the shallow grooves, the luminous component of LED wafer is exposed to outside the through hole of reflective cup, the back side of LED wafer is glued with the heat dissipation metal body, and heat dissipation metal body and reflective cup are fastenedly connected.
2. LED reflector according to claim 1 is characterized in that being coated with heat-conducting glue between LED wafer and the heat dissipation metal body.
