Abstract
The utility model discloses a COB-LED (chip on board light-emitting diode) reflector lamp which comprises a lamp holder and a shell connected with the lamp holder. The shell is a hollow shell with one open end, a power supply, a cooling component, a COB surface light panel and a reflecting cover with a lens are arranged inside the shell, the power supply and the cooling component are fixed into the shell, the reflecting cover with the lens is fixed to the open end of the shell, the cooling component comprises a cooling aluminum ring and a cooling fan, the COB surface light panel is mounted on the cooling aluminum ring, and the cooling fan is fixed onto the cooling aluminum ring. A COB light source and the power supply are integrally arranged in the shell, the reflector lamp is small in mounting size, heat transfer and cooling are rapid by the aid of the fan and the cooling aluminum ring, and long-life normal operation of the reflector lamp can be ensured.
Description
Technical field
The utility model relates to a kind of light fixture, specifically relates to a kind of COB-LED shot-light.
Background technology
In LED lighting, adopt COB(chip on board, chip on board encapsulation) area source, light is soft, and brightness is high, can be applied to indoor, commercial lighting field, as LED bulb lamp, LED shot-light, LED Down lamp, LED Ceiling light, LED track lamp etc.As COB-LED shot-light, during work, to send amount of heat, a technical problem that solve is under less overall volume, to guarantee good heat radiation.Current COB-LED shot-light, in order to improve radiating effect, generally need to be done the surface areas such as shell greatly when making, and makes like this small product size increase, and weight increases, and hangs inconvenience, also affects spatial decoration attractive in appearance.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above defect, proposes the COB-LED shot-light of the little good heat dissipation of a kind of volume.
Technical problem of the present utility model realizes by following technological means.
A kind of COB-LED shot-light, comprise lamp holder, the shell being connected with lamp holder, described shell is the uncovered hollow shell in one end, its inside is provided with power supply, radiating subassembly, COB face tabula rasa, with the reflection shield of lens, described power supply and radiating subassembly are fixed on enclosure, and the described reflection shield with lens is fixed on shell opening end; Described radiating subassembly comprises radiation aluminium circle and radiator fan, and described COB face tabula rasa is mounted on radiation aluminium circle, and described radiator fan is fixed on radiation aluminium circle.
Also comprise support, described support is fixed on radiation aluminium circle and compresses COB face tabula rasa, and described reflection shield one end with lens is stuck on the draw-in groove of offering on support, and the other end withstands the fixture block at shell opening end edge.
Described radiation aluminium circle and power supply are screwed on shell.
The described reflection shield back with lens is provided with electrodeposited coating.
The utility model is compared with the prior art the beneficial effect having: in the utility model, adopt COB light source and power supply one to establish in the enclosure, installation volume is little, adopts fan and radiation aluminium circle, conducts heat and rapid heat dissipation, has guaranteed that shot-light can long-life normal work.
Accompanying drawing explanation
Fig. 1 is the structure chart of the specific embodiment.
Fig. 2 is with the structure chart of the reflection shield of lens in Fig. 1.
The specific embodiment
A COB-LED shot-light, as shown in Figure 1, comprises reflection shield 1, support 2, COB face tabula rasa 3, radiation aluminium circle 4, screw 5, radiator fan 6, power supply 7, shell 8, lamp holder 9 with lens.
Shell 8 is hollow, and one end is uncovered, and the other end is connected with lamp holder 9, and conical plastics material is used for protecting its inner power supply and light source.Power supply 7 is stuck in shell 8 internal collars, connects with lamp holder 9 electricity, gives COB face tabula rasa 3 power supplies.Radiator fan 6 and radiation aluminium circle 4 are thermal component, heat radiation while working for COB face tabula rasa, and radiation aluminium circle 4 is fixed on shell 8 by screw 5, and radiator fan 6 mounts and is fixed on radiation aluminium circle 4 one sides.The illuminating source that COB face tabula rasa 3 is 15W to 40W, is mounted on radiation aluminium circle 4 another sides, connects with power supply 7 electricity.Support 2 use screws 5 are fixed on radiation aluminium circle 4 and the same side that mounts COB face tabula rasa, also compress COB face tabula rasa 3 simultaneously.Beam angle with the reflection shield 1 of lens is 10 °-40 °, and one end is stuck on the draw-in groove of offering on support 2, and the other end withstands the fixture block at shell 8 opening end edges and fixes.As shown in Figure 2, with the reflection shield 1 of lens, be conical, near one end of light source, be provided with lens 10, the back of reflection shield 1 is electrodeposited coating 11, through the light of lens 10, can penetrate by almost parallel.
During assembling, take radiation aluminium circle 4 as pedestal, COB light source 3 is mounted on to one side, with screw 5, support 2 is fixed on to its same side, with one end of the reflection shield 1 of lens, be stuck on the draw-in groove of support 2; Radiator fan 6 is loaded onto in another relative side at radiation aluminium circle 4; With screw 5 by power supply 7 be fixed on the interior sky of shell 8 in; Radiation aluminium circle 4 use screws 5 are fixing with shell 8, with reflection shield 2 fastenings of lens at shell 8 opening end edges.
Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
