Description

An improved LED downlight

technical field

The utility model relates to a lamp, in particular to an improved LED downlight.

Background technique

With the gradual improvement of LED technology, the various performances of LED lamps for lighting have been greatly improved, and because of the advantages of high brightness, long life and significant energy saving, LED products have been widely recognized and have become the mainstream of energy-saving lamps. Existing LED downlights all have very dazzling glare, which can hardly be seen directly. Although some existing enterprises use frosted covers to deal with glare, the elimination is still incomplete. China Patent No.: 201020631514.4 discloses that the utility model discloses an LED downlight, including a lamp body part and a power supply part, the lamp body part is connected to the power supply part, the lamp body part includes a downlight base, a lens, and a There is an LED light source, the lens is arranged at the opening of the base of the downlight, and a light guide ring is also arranged at the junction of the lens and the base of the downlight. It can reduce light loss, the power supply part and the lamp body part are integrated, and the heat dissipation effect is good, but it still cannot eliminate glare, making people unable to look directly at it.

Utility model content

Therefore, aiming at the above problems, the utility model proposes an improved LED downlight with simple structure, novel shape, unique structure, glare elimination and good lighting effect.

In order to solve this technical problem, the utility model adopts the following solutions: an improved LED downlight, including a downlight housing, a plurality of LED light bars, a lens, a power module, a radiator and an aluminum substrate, and the lens is embedded in the tube At the opening in front of the bottom of the lamp housing, one end of the radiator is fixedly connected to the aluminum substrate, and the other end of the radiator is fixedly connected to the power module. It also includes multiple reflectors, and the aluminum substrate is fixed on the bottom of the downlight housing. , the inner wall of the downlight housing is provided with a reflective layer, and the side of the aluminum base plate away from the radiator is evenly provided with a plurality of convex lines with a triangular cross-section, and the inclined surfaces of each of the convex lines are respectively provided with For the LED light bar, each reflector plate is respectively arranged between every two convex strips, and each LED light bar is electrically connected to the power module through wires penetrating through the aluminum substrate and the heat sink.

A further improvement is to define an angle A formed between the hypotenuse of the convex line and the horizontal line of the aluminum substrate, and the angle A is 130°-140°.

As a further improvement, the reflective plate is 2-5cm higher than the top of the convex strip.

By adopting the aforementioned technical scheme, the beneficial effect of the utility model is: by setting the LED light bar on the inclined surface of the convex strips of the aluminum substrate, and at the same time setting a reflective plate between the convex strips, and setting a reflective layer on the inner wall of the downlight housing, As a result, the light emitted by the LED light bar is reflected from the lens through the reflective plate and the reflective layer, so that even if people look directly at the downlight, there will be no glare. At the same time, it has the advantages of good lighting effect, novel shape, and unique structure. Promote apps.

Description of drawings

Fig. 1 is a schematic diagram of a cross-sectional structure of an embodiment of the utility model.

Detailed ways

The utility model is further described now in conjunction with accompanying drawing and specific embodiment.

Referring to Fig. 1, the preferred improved LED downlight of the present invention includes a downlight housing 1, a plurality of LED light bars 2, a lens 3, a power module 4, a radiator 5, an aluminum substrate 6 and a plurality of reflectors 7 The lens 3 is embedded in the front opening of the bottom of the downlight housing 1, one end of the radiator 5 is fixedly connected to the aluminum substrate 6, the other end of the radiator 5 is fixedly connected to the power module 4, and the aluminum substrate 6 is fixed Located at the bottom of the downlight housing 1, the inner wall of the downlight housing 1 is provided with a reflective layer 11, and the outer wall of the downlight housing 1 is symmetrically provided with a pair of elastic buckles 12, which are used for hanging the downlight , the side of the aluminum substrate 6 far away from the radiator 5 is evenly provided with a plurality of convex strips 61 with a triangular cross-section, and LED light strips 2 are respectively arranged on the inclined surfaces of each of the convex strips 61. The reflectors 7 are respectively arranged between every two convex strips 61, and the LED light strips 2 of each strip are electrically connected to the power module 4 through the aluminum substrate 6 and the heat sink 5, defining the hypotenuse of the convex strips 61 and The included angle A formed between the horizontal lines of the aluminum substrate 6 is 135°, and the reflector 7 is 3 cm higher than the top of the triangular tip of the convex strip 61 .
