Description

The LED projecting lamp

Technical field

The utility model relates to a kind of LED projecting lamp.

Background technology

General projecting lamp is to be used in exhibition guild hall, department store's Window Display cabinet ... or the like, under the irradiation of projecting lamp light source, make displaying articles more beautiful, increase the texture of displaying articles, thereby improve the value of article itself, attract consumer's sight; Be must project graceful light type with described projecting lamp, form own also should have attractive in appearance and the refracted ray aesthetic feeling simultaneously, to set off overall value, more augments the aesthetic feeling of display case.

Yet, seeing also Fig. 1 is existing LED projecting lamp figure, it mainly is that the number LEDs directly is connected on the control circuit board for described existing projecting lamp A, and with described ccontaining being positioned in the lampshade 100 of control circuit board that is connected with several LEDs, and on described light cover 200, connect intrinsic several optical lens, rely on the described optical lens of screw 300 lockings in light cover 200 and lampshade 100, can form one is the lamp body of light emitting source with LED, uses for projection illumination;

Wherein, though described existing projecting lamp can be used as the light emitting source of lamp body, but it still has following disappearance: described existing LED directly is connected on the control circuit board, it there is no any radiating module is set, the heat energy that makes LED produce can't reach better heat radiating effect, and then shortens the service life of LED and electronic component; Existing LED projecting lamp by directly light cover being locked at lampshade, makes screw exposed outside, very not attractive in appearance with screw outward; Existing projecting lamp, behind the optical lens refracted ray, no transmission effects can not increase the atmosphere aesthetic feeling.

Therefore, how above-mentioned disappearance is forgone, be the place of the technical difficulties of this case utility model designer institute desire solution.

Compared with prior art, adopt the outstanding advantage that the utlity model has of technique scheme.

Existing disappearance:

1. existing projecting lamp does not have radiating fin, and the heat energy that LED is produced can not good heat radiating, and then impairment LED service life.

2. existing projecting lamp penetrates the screw hole locking and uses on the light cover plate, make outward appearance have the exposed structure external form of screw very not attractive in appearance.

3. existing projecting lamp, behind the optical lens refracted ray, the ring plate of the translucent color of the described tool of no transmission can not increase the atmosphere aesthetic feeling.

Advantage of the present utility model:

1. the utility model is provided with platen surface, radiating fin, and the heat energy that LED is produced reaches better heat radiating effect, and then prolongs LED service life.

2. light cover plate of the present utility model rear is provided with the screw hole locking that does not penetrate and uses, and makes outward appearance not have the exposed structure external form grace of screw.

3. optical lens refracted ray of the present utility model, the ring plate of the translucent color of the described tool of transmission increase aesthetic feeling atmosphere and form protection.
