Problems solved by technology

[0003] At present, star projection lamps on the market usually use laser diodes or LEDs as light sources, but laser diodes are almost monochromatic in red, green and blue, and cannot effectively synthesize white, so it is difficult to form white patterns; when using LEDs as light sources, in order to ensure Starry sky projection effect, usually only part of the light can be used, which reduces the utilization rate of the light source

Embodiment 1

[0027] like figure 1 As shown, the present invention provides a lamp, including a light source 10, the light emitted by the light source 10 is divided into two parts, wherein the first part of the light 101 is projected onto the projection unit 20 and emerges to form a star projection lamp, and the second part of the light 102 Projected onto the lighting unit 30 to form a lighting lamp. Preferably, the light source 10 can be a single-color LED light source or a multi-color LED light source, such as a white LED light source or a four-color LED light source, which respectively form a single-color or colored projection and lighting effect. Of course, it can also be other light sources, which will not be described here. limit. Specifically, a part of the light emitted by the light source 10 is projected onto the projection unit 20 to finally form a starry sky projection effect, which can play the role of creating an atmosphere and decorating; The role of lighting, the lamp has t...

Embodiment 2

[0036] like Figure 4-5 As shown, different from Embodiment 1, the optical guiding unit further includes a beam splitting unit 420 arranged behind the concave lens 410 along the optical path, and the beam splitting unit 420 includes a solid transparent member, and the solid transparent member Including an incident surface 421, a reflecting surface 422 and an outgoing surface 423, the reflecting surface 422 is a total internal reflection surface, and the light beam passing through the concave lens 410 passes through the incident surface 421 and the outgoing surface 423 or sequentially passes through the incident surface 421 , the reflective surface 422 and the outgoing surface 423 form a plurality of sub-beams with different propagation angles, and the sub-beams are projected onto the collimating lens 210 to be collimated and then incident on the mirror array 220 . Specifically, the solid transparent part divides the light beam passing through the concave lens 410 into multiple...

Embodiment 3

[0039] like Image 6 As shown, a uniform light guide 50 is sheathed on the outer periphery of the light source 10 , and the second part of light 102 is evenly projected onto the lampshade 310 after passing through the light uniform guide 50 . Specifically, the uniform light guide 50 can be a transparent lens or a transparent lampshade with uniform light and guiding functions, or other components that can realize the above functions. Image 6 Among them, the uniform light guide 50 is a hollow transparent lens, and the lens includes at least one side surface and a top surface. The first part of the light 101 exits after passing through the top surface of the lens, and enters the projection unit for use as projection light. The second part of the light 102 exits after passing through the side of the lens, and is projected onto the lampshade 310 for use as illumination light. In this embodiment, by optically designing the side of the uniform light guide 50 , the second part of li...

Abstract

The invention discloses a lamp, comprising a light source, wherein light emitted by the light source is divided into two parts, the first part of light is projected to a projection unit and exits to form a starry sky projection light, and the second part of light is projected to an illuminating unit to form an illuminating light. One part of light emitted by the light source is projected to the projection unit, to finally form a starry sky projection effect, and then play the roles of creating atmosphere and decorating; the other part of light is projected to the illuminating unit, to form a lighting effect of illuminating, so as to play a role of illuminating; the light has two module functions including the starry sky projection light and the illuminating light, and thus not only increasing the utilization rate of the light source, and avoiding light waste, but also improving the use diversity of the lamp, and meeting more use requirements; and the lamp is small in volume, low in cost and wider in application.

Description

technical field [0001] The invention relates to the technical field of decoration and lighting, in particular to a lamp. Background technique [0002] Star projection lamp is a decorative lighting device that projects countless stars or snowflakes on the walls, ceilings, and lawns. It is used indoors such as KTV boxes, and outdoors such as courtyards, lawns, and plants. It can create atmosphere and decorate The role of landscape has a very wide range of applications in life. [0003] At present, star projection lamps on the market usually use laser diodes or LEDs as light sources, but laser diodes are almost monochromatic in red, green and blue, and cannot effectively synthesize white, so it is difficult to form white patterns; when using LEDs as light sources, in order to ensure For the starry sky projection effect, usually only part of the light can be used, which reduces the utilization rate of the light source. Contents of the invention [0004] Aiming at the problem...
