Abstract

The utility model discloses a light source modular LED (Light Emitting Diode) down lamp. A light source part of the LED down lamp is designed in a modular way; a mounting ring for wrapping an LED light source therein is connected with a flange at the bottom of a radiator through thread in a matching way; a lower end face of the mounting ring is provided with an annular stop edge which wraps the outer side of the LED light source; through the structure, the LED light source and the radiator form a light source module; when the light source part is required to be maintained and replaced, only the mounting ring on the LED light source is required to be screwed off from the radiator to finish the disassembly work of the LED light source; and thus, the light source modular LED down lamp has the advantages of convenience in disassembly and convenience in maintenance and replacement of the light source accessory.

Description

Light source module type LED Down lamp

Technical field

The utility model relates to lighting field, mentions a kind of light source module type LED Down lamp especially.

Background technology

In lighting field, emerging LED semiconductor lighting technical application is just increasingly extensive.In the LED light fixture, the LED Down lamp is a kind of application LED light fixture more widely, is used for the trade dress illumination more.The structure of existing LED Down lamp generally all is an overall structure, and led light source partly is fixedly installed in cylindrical case inside; The installation that before dispatching from the factory, all has been fixed of led light source part; If when the LED Down lamp had the necrosis of partial L ED light to need to change, the user can not be from line operate, because unloading process extremely bothers; Can only entrust manufacturer to keep in repair, user's use is caused inconvenience.

The utility model content

To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of light source module type LED Down lamp, and it has the Lights section can be for convenience detach, is convenient to the advantage of maintain and replace light source accessory.

To achieve these goals; The technical scheme that the utility model adopted is: light source module type LED Down lamp; Comprise shell and be installed on the light source module in the shell, it is characterized in that said light source module comprises radiator and led light source; Also comprise led light source is coated on interior installing ring, the lower surface of said installing ring has the outside that the ring-type rib is coated on led light source; Said radiator bottom has flange, and the upper surface of said installing ring is placed on the said flange and both are through the threaded engagement connection.

Preferably, said led light source comprises light source cover, optical lens and the LED lamp plate that fits together successively, between said LED lamp plate is connected through screw with the light source cover and is clipped in said optical lens wherein.

Preferably, the thickness of flange on the said radiator is greater than the spacing between the said LED lamp plate back side and the said installing ring upper surface.

Preferably, said radiator center has through hole, the LED lamp plate back side of the said light source module of said through-hole alignment.

The utility model is compared the advantage that is had with prior art: through the Lights section modularity design with the LED Down lamp; Led light source is coated on the flange of interior installing ring and said radiator bottom; Both connect through threaded engagement, and the lower surface of said installing ring has the outside that the ring-type rib is coated on led light source, make led light source and radiator composition light source module through said structure; At needs during to the Lights section maintain and replace; Only need the installing ring on the led light source be backed out the dismantlement work that can accomplish led light source from radiator, therefore the utlity model has the Lights section can be for convenience detach, is convenient to the advantage of maintain and replace light source accessory.

The specific embodiment

The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.

Embodiment, see that Fig. 1 is to shown in Figure 5:

The utility model is a kind of light source module type LED Down lamp; Comprise shell 10 and be installed on the light source module 20 in the shell 10; It is characterized in that; Said light source module 20 comprises radiator 21 and led light source 22, also comprises led light source 22 is coated on interior installing ring 23, and the lower surface of said installing ring 23 has the outside that ring-type rib 24 is coated on led light source 22; Said radiator 21 bottoms have flange 25, and the upper surface of said installing ring 23 is placed on the said flange 25 and both are through the threaded engagement connection.The utility model is through the Lights section modularity design with the LED Down lamp; Led light source 22 is coated on the interior installing ring 23 and the flange 25 of said radiator 21 bottoms; Both connect through threaded engagement, and the lower surface of said installing ring 23 has the outside that ring-type rib 24 is coated on led light source 22, make led light source 22 and radiator 21 form light source modules 20 through said structure; At needs during to the Lights section maintain and replace; Only need the installing ring on the led light source 22 23 be backed out the dismantlement work that can accomplish led light source 22 from radiator 21, therefore the utlity model has the Lights section can be for convenience detach, is convenient to the advantage of maintain and replace light source accessory.

Such scheme is more convenient when changing whole LED light source 22, if but when having only minority light downright bad in the led light source 22, change whole LED light source 22 and seem that relatively waste and cost are higher, therefore only need change wherein downright bad light and get final product.For the replacing that makes light also more convenient easily; Said led light source 22 comprises the light source cover 26 that fits together successively, optical lens 27 and LED lamp plate 28, between said LED lamp plate 28 is connected through screw with light source cover 26 and is clipped in said optical lens 27 wherein.Only need the screw on the LED lamp plate 28 be backed out when changing light, bulb downright bad on the LED lamp plate 28 is pulled down and welded again and go up new bulb.

In addition; For being conducted on the radiator 21 fast, distributes heat on the led light source 22; The radiating effect that adds intense light source module 20, flange 25 thickness on the said radiator 21 are greater than the spacing between said LED lamp plate 28 back sides and said installing ring 23 upper surfaces, after led light source 22 is tight through the installing ring 23 and flange 25 threaded engagement of radiator 21; The back side of the LED lamp plate 28 of the lower surface of flange 25 and led light source 22 can fit tightly, the accelerated heat conduction; Simultaneously, said radiator 21 centers have through hole 29, and said through hole 29 is aimed at LED lamp plate 28 back sides of said light source module 20, and the heat on the LED lamp plate 28 can be distributed through cross-ventilation from through hole 29.

The light source module type LED Down lamp of the utility model, having the Lights section can be for convenience detach, is convenient to the advantage of maintain and replace light source accessory.
