Description

Lamp

The present invention relates to a luminaire, and more particularly to a luminaire for use in an indicator light.

The inner and outer surfaces of the lampshade of the conventional lamp are generally smooth, and the manufacturing method is simple, and has an aesthetic advantage.

However, if it is to be applied to the indicator light, since the main function of the indicator light is to remind other drivers that the vehicle is about to turn, the light emitted by the indicator light needs to have a wide range to remind other drivers to pay attention, but the traditional light fixture has its lampshade. The inner and outer surface shapes are all smooth surface design, which can not effectively diffuse the transmitted light at a large angle, so it has the disadvantage of small light exit angle, and is not suitable for application to the indicator light.

Therefore, the purpose of the present invention is to provide a luminaire that has a large light-emitting angle and can achieve a wide range of warning effects.

Therefore, the novel lamp comprises a base, a light emitting unit disposed on the base, and a lamp cover disposed on the base and covering the light emitting unit. The lampshade includes a first diverging region, the first diverging portion has a plurality of first diverging portions, each of the first diverging portions includes a light incident surface and a light exiting surface, and each of the first diverging portion has a light incident surface that is outwardly convex The curved surface of each of the first diverging portions is an inwardly concave curved surface, and the first diverging portions are configured to increase the light exiting angle of the light emitted by the light emitting unit.

The effect of the novel is that the light-shielding surface of the first diverging portion is matched with the shape of the light-emitting surface, and the light emitted by the light-emitting unit can be effectively diverged at a large angle, thereby increasing the overall brightness of the light-emitting device. The light-emitting angle enables the luminaire to be applied to the indicator light to achieve a wide range of warning effects to alert other drivers.

Other features and effects of the present invention will be apparent from the following description of the drawings. FIG. 1 is an exploded perspective view of a first embodiment of the present luminaire; FIG. 2 is the first embodiment. 3 is a cross-sectional view taken from line III-III in FIG. 2; FIG. 4 is a perspective assembled view of a second embodiment of the novel lamp; and FIG. 5 is from FIG. A cross-sectional view taken of the straight line VV.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , a first embodiment of the novel lamp comprises a base 1 , a lighting unit 2 and a lamp cover 3 . The base 1 includes a side plate 11 and a reflection plate 12 connecting the side plates 11. The light-emitting unit 2 includes a plurality of light-emitting elements 21, which are disposed on the side panel 11. The reflector 12 has a first reflective area 121 and a second reflective area 122. The lamp cover 3 includes a first diverging area 31 corresponding to the first reflective area 121, and a second diverging area 32 having a plurality of first diverging portions 311, and the first diverging portions The 311 is closely connected to each other, and the second diverging region 32 has a plurality of second diverging portions 321 .

Each of the first diverging portions 311 includes an outwardly convex and spherical light incident surface 312, and an inwardly concave and spherical light emitting surface 313. Each of the second diverging portions 321 includes a light-incident surface 322 that protrudes outward and has a spherical surface, and a light-emitting surface 323 that is a smooth surface. The first reflective area 121 of the reflector 12 can reflect light from the light-emitting elements 21 to the first diverging region 31 of the reticle 3, and the first diverging portions 311 of the first diverging region 31 are The planes of the light incident surface 312 and the light exit surface 313 cooperate to divergence the transmitted light from the first reflective region 121 at a large angle to increase the light exit angle. However, most of the light will penetrate the lamp cover 3, and a small portion of the light is reflected back to the reflector 12 by the lamp cover 3. The second reflection area 122 of the reflector 12 can reflect the light reflected by the lamp cover 3 to a second diverging region 32 of the reticle 3, the second diverging portions of the second diverging region 32 The 321 is matched by the surface shape of the light incident surface 322 and the light exit surface 323, thereby diffusing the light from the second reflective region 122 at a large angle to increase the light exit angle.

Referring to FIG. 4 and FIG. 5, a second embodiment of the luminaire of the present invention is different from the first embodiment in that the light-emitting surface 323 of each second diverging portion 321 is inwardly recessed and spherical. The surface design of the light incident surface 312 and the light exit surface 313 of the first diverging portion 311 of the first diverging region 31 of the globe 3 is further matched with the light entering the second diverging portion 321 of the second diverging region 32. The surface design of the surface 322 and the light-emitting surface 323 can effectively diffuse the light emitted by the light-emitting unit 2 at a large angle, so that the overall light-emitting angle of the light-emitting unit is larger and the warning range is wider, which makes it easier for other drivers to notice. .

In summary, the light-emitting surface 312 and the light-emitting surface 313 of the first diverging portion 311 of the first diverging portion 31 of the lamp cover 3 are designed to match the second divergent region 32. The surface design of the light-incident surface 322 and the light-emitting surface 323 of the second diverging portion 321 can increase the light-emitting angle of the light emitted by the light-emitting unit 2 via the light cover 3, and can be more easily reminded by being applied to the indicator light. The driver pays attention, so it can achieve the purpose of this new type.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
