Range, to achieve increased brightness and efficiency of lighting.

According to the LED projection lamp, it is often used for architectural decoration lighting, such as interior decoration, space design, exhibition hall, exhibition lighting, and common lighting sources for exhibition venues. It is also often used in hypermarkets, outdoor sets, dance halls. KTV, PUB, as well as stage, performing arts occasions, exhibitions, restaurants, galleries, etc., can use LED projection lamps for the most outdoor lighting to highlight the contours of large buildings, exterior lighting of buildings, exterior lighting in buildings, indoor lighting LED lighting, LED lighting, billboard lighting, medical, cultural and other special facilities lighting, even the atmosphere of lighting in bars, dance halls and other entertainment venues, can use LED projection lights.

However, LED products are mainly due to excessive temperature, which will affect the LED product life cycle, luminous efficiency and luminous stability. Therefore, the design of heat dissipation has always been an important issue in LED lighting related products. In particular, LED projection lamps have stronger light sources and longer illumination time. Therefore, manufacturers must overcome the heat dissipation problem of LED projection lamps. .

In order to enhance the heat dissipation effect, the conventional LED projection lamp often adds an additional structure for promoting heat dissipation on the LED projection lamp. However, the conventional heat dissipation structure of the LED is large in size, heavy in weight, high in cost, and difficult to be used. Process assembly is not suitable for mass production, and maintenance is difficult. Moreover, although it is a heat dissipation structure, the heat dissipation area is insufficient, and the heat dissipation effect is not ideal, which is quite troublesome.

The creator specializes in the R&D and design of LED luminaires. It is well known that the use of traditional LED projection lamps does not meet the needs. It is necessary for reform, so it is the determination to create a creation, and with its own professional and years of experience. Work experience, finally after several trials, corrections and improvements, the first creation of this creation.

The present invention relates to an improvement of the structure of an LED projection lamp, in particular to a base having a heat dissipation function, and an improved structure of the LED projection lamp capable of improving the illumination range through the inclination angle of the base. The utility model mainly comprises a heat dissipation base, a light board and a lamp cover, wherein the heat dissipation base is formed by two sets of bilaterally symmetrical aluminum extruded bases, which are hollow and have a circular through hole and a number. a heat dissipation through hole and a heat dissipation fin; and the front surface of the heat dissipation base is a central protrusion, which is inclined to both sides to form two angled slopes, each of which is provided with a light board, and the lamp board is provided with a plurality of lamp beads; The utility model is embedded in the heat dissipation base and fixed by the positioning piece. When the two sets of left and right symmetrical bases are screwed together, and the assembly of the light board and the lamp cover is completed, the upper cover having the through hole corresponding to the heat dissipation base is further disposed. And the lower cover is screwed.

In use, the light board is respectively disposed on the angled slope of the heat dissipation base. When the light bulb on the light board is excited, the inclined surface of the LED lamp can be irradiated to a wider range, and the illumination area thereof is generated. Overlap, which can make the target of the projection receive more light sources, and the effect of the illumination is more obvious, so the brightness and efficiency of the illumination of the LED projection lamp can be increased; and the combined heat dissipation base can not only provide excellent performance. The heat dissipation effect is simple in assembly, which can improve production efficiency and reduce manufacturing cost, and is also convenient in future maintenance. It is obviously more practical and convenient than the conventional LED projection lamps.
