Description

TECHNICAL FIELD

[0001] The utility model relates to the field of lamps and lanterns, concretely relates to a light projecting lamp with good heat dissipation effect and long service life. BACKGROUND

[0002] Light projecting lamps are widely used in large-area work sites, building outlines, stadiums, overpasses, monuments, parks and flower beds and the like due to their unique lighting effect and wide application range. In these occasions, light projecting lamps can provide high-brightness and uniform lighting effect, meeting people's demand for lighting. The heat dissipation structure of the existing light projecting lamp has poor heat dissipation effect, resulting in a large amount of heat generated in the working process of the light projecting lamp. The heat cannot be dissipated in time, which will cause the temperature of the light source board chip to be too high. This will not only affect the light efficiency of the light projecting lamp and cause the light emitting efficiency to decrease, but also cause the lamp beads to burn out and the like, thereby greatly shortening the service life of the light projecting lamp. SUMMARY

[0003] The utility model solves the problem of poor heat dissipation effect of the existing light projecting lamp.

[0004] To achieve the above-mentioned purpose, the utility model provides a light projecting lamp, which comprises an aluminum die-casting lamp body, tempered glass and a support. The aluminum die-casting lamp body is surrounded by a peripheral protruding side wall to form a mounting groove. A light source board is attached to the bottom wall of the mounting groove. The back of the aluminum die-casting lamp body is provided with a plurality of heat dissipation strips. The heat generated when the light source board works can be quickly dissipated through the heat dissipation strips.

[0005] Further, the opening part of the mounting groove is provided with a glass placing groove, the tempered glass is arranged in the glass placing groove, and the light source board is arranged in the glass placing groove.

[0006] Further, the support comprises a first hinge part, a second hinge part and a connecting rod. The first hinge part and the second hinge part are connected by the connecting rod. The first hinge part is hingedly connected to one side of the aluminum die-casting lamp body by a hinge part, and the second hinge part is hingedly connected to the other side of the aluminum die-casting lamp body by a hinge part.

[0007] Further, the heat dissipation strips on the back of the aluminum die-casting lamp body are arranged vertically, and a heat dissipation channel is formed between each heat dissipation strip.

[0008] Further, the heat dissipation strips are integrally formed with the aluminum die-casting lamp body.

[0009] The utility model has the following technical effects and advantages: the back of the aluminum die-casting lamp body is provided with a plurality of integrally formed heat dissipation strips. The heat in the lamp can be quickly dissipated through the heat dissipation channels formed between the heat dissipation strips, thereby prolonging the service life of the lamp.

[0011] Fig. 2 is a back view of the utility model;

[0012] Fig. 3 is an exploded view of the utility model;

[0013] The drawing reference: die-casting aluminum lamp body 10, toughened glass 20, support 30, installation recess 11, light source plate 12, heat dissipation strip 13, glass placing groove 14, first hinged part 31, second hinged part 32, connecting rod 33, hinged component 34, heat dissipation channel 15. DETAILED DESCRIPTION

[0014] As Figs. 1 to 3 the utility model discloses a projecting lamp, including die-casting aluminum lamp body 10, toughened glass 20 and support 30, the die-casting aluminum lamp body 10 is formed installation recess 11 through the side wall of the peripheral convex, the bottom wall of installation recess 11 is attached with light source plate 12, the back of die-casting aluminum lamp body 10 is equipped with a plurality of heat dissipation strips 13, and the heat generated when the light source plate works can be quickly dissipated through the heat dissipation strip.

[0015] The opening part of installation recess 11 is equipped with glass placing groove 14, the toughened glass 20 is located in the glass placing groove 14, and the light source plate 12 is located in the glass placing groove 14, so that the toughened glass 20 can prevent foreign matters from affecting the normal use of the lamp in the interior of the lamp body when in use.

[0016] The support 30 includes a first hinged part 31, a second hinged part 32 and a connecting rod 33, the first hinged part 31 and the second hinged part 32 are connected through the connecting rod 33, the first hinged part 31 is hinged to one side of the die-casting aluminum lamp body 10 through the hinged component 34, the second hinged part 32 is hinged to the other side of the die-casting aluminum lamp body 10 through the hinged component 34, so that the support 30 and the die-casting aluminum lamp body 10 can be flipped with the hinged component 34 as the center to adjust the angle.

[0017] The heat dissipation strip 13 of the back of the die-casting aluminum lamp body 10 is vertically arranged, and the heat dissipation channel 15 is formed between each heat dissipation strip 13, so that the flowing air can quickly take away the heat of the lamp body through the heat dissipation channel 15 of the back of the die-casting aluminum lamp body 10 to accelerate the heat dissipation effect when in use.

[0018] In summary, the projecting lamp of the utility model, the back of the die-casting aluminum lamp body 10 is provided with a plurality of integrally formed heat dissipation strips 13, and the heat dissipation channel 15 formed between the heat dissipation strips 13 can quickly dissipate the heat in the lamp, thereby prolonging the service life of the lamp.
