Description

Ceiling light

The present invention relates to a lamp, and in particular to a ceiling lamp.

Lighting allows people to carry out various outdoor activities at night. Besides lighting, it also has the functions of decoration, atmosphere creation and visual change. Moreover, according to different usage environments and purposes, there are many types and styles of lights, such as ceiling lights, chandeliers, table lights, wall lights, floor lights, spotlights, etc. Among them, ceiling lights have various advantages such as space saving, uniform lighting, various design styles, various sizes, and high safety. They have become one of the most popular lights in recent years.

However, ceiling lamps are mainly used for downward lighting, so during use, the environmental experience is mainly changed through different methods such as the brightness, color temperature, and shape of the bulb. The above-mentioned change methods can no longer produce more visual change experiences to meet user needs.

Therefore, it is necessary to provide a novel and advanced ceiling lamp to solve the above problems.

The main purpose of the present invention is to provide a ceiling lamp, which can produce a variety of lighting scene changes and enrich the lighting effect by irradiating the supporting surface with a second light-emitting unit to form reflected light, and at the same time cooperate with the direct light of the first light-emitting unit below.

To achieve the above-mentioned object, the present invention provides a ceiling lamp, comprising: a lamp holder, a first light-emitting unit and a second light-emitting unit. The lamp holder is defined with a first side and a second side, the second side facing a support surface; the first light-emitting unit is disposed on the lamp holder at the first side; the second light-emitting unit is disposed on the lamp holder at the second side.

The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention. The "one" or "at least one" preceding the terms mentioned in the text does not limit the quantity, and it can also be "plural" according to needs. This change in quantity is also within the scope of protection, which should be explained in advance.

Please refer to FIG. 1 to FIG. 8 , which show an embodiment of the present invention. The ceiling lamp of the present invention includes: a lamp holder 1, a first light-emitting unit 3 and a second light-emitting unit 4.

The lamp holder 1 is defined with a first side 11 and a second side 12, wherein the second side 12 faces a supporting surface 7, such as a ceiling. The first light unit 3 is disposed on the lamp holder 1 at the first side 11 to illuminate the space below, and the second light unit 4 is disposed on the lamp holder 1 at the second side 12 to illuminate the space above. In this way, in addition to being able to fully illuminate the environment with two different directional light sources, the first light unit 3 provides direct light, and the second light unit 4 provides reflected light, and the combination of the two can produce more different lighting effects and lighting situations.

More specifically, the lamp holder 1 includes a positioning seat body 13 and a connecting seat body 2. The positioning seat body 13 is used to be positioned on the supporting surface 7. The positioning seat body 13 can be detachably assembled to the connecting seat body 2. The first light-emitting unit 3 is disposed on the connecting seat body 2, and the second light-emitting unit 4 is disposed on the positioning seat body 13.

More specifically, the positioning base 13 is combined with the connecting base 2 along an assembly direction 6, and the positioning base 13 is provided with a first light-transmitting portion 14 in a direction transverse to the assembly direction 6. The second light-emitting unit 4 is accommodated in the positioning base 13 and part of the light can penetrate through the first light-transmitting portion 14, that is, part of the light of the second light-emitting unit 4 is emitted in a direction transverse to the assembly direction 6. In this embodiment, the second light-emitting unit 4 is in a strip shape, and the second light-emitting unit 4 extends along the circumference of the positioning base 13, and a light-emitting side 41 of the second light-emitting unit 4 faces the first light-transmitting portion 14, so that most of the light is mainly penetrated from the first light-transmitting portion 14.

Preferably, the positioning base 13 further includes a second light-transmitting portion 15, and the connecting base 2 includes a third light-transmitting portion 21. When the positioning base 13 is assembled to the connecting base 2, the second light-transmitting portion 15 and the third light-transmitting portion 21 are arranged along the assembly direction 6, and part of the light from the second light-emitting unit 4 can penetrate the second light-transmitting portion 15 and the third light-transmitting portion 21. The light from the second light-emitting unit 4 can assist in illuminating the space below. For example, when the first light-emitting unit 3 does not emit light, the second light-emitting unit 4 can be used as a night light to illuminate the upper and lower spaces at the same time.

Another preferred embodiment is that the entire positioning base 13 is made of a light-transmitting material, thereby allowing the light from the second light-emitting unit 4 to penetrate more fully and widely.

The connecting seat 2 further includes a main component 22 and a sub-component 23, wherein the sub-component 23 is detachably mounted on the main component 22, and the positioning seat 13 is assembled to the main component 22. In a direction perpendicular to the assembly direction 6, the maximum size of the main component 22 is larger than the maximum size of the positioning seat 13. The main component 22 can be mass-produced as a core basic component with a unified size, while the peripheral sub-components 23 can have different sizes depending on the needs of consumers, so as to facilitate assembly into the connecting seat 2 after batch production.

Preferably, the first light emitting unit 3 includes a plurality of first light emitting bodies 31 and a plurality of second light emitting bodies 32 which are separably connected in series with each other. The plurality of first light emitting bodies 31 are disposed on the main component 22, and the plurality of second light emitting bodies 32 are disposed on the auxiliary component 23, so as to facilitate disassembly and separation.

Another preferred embodiment is that the entire main component 22 is made of a light-transmitting material so as to have a wider light-transmitting range, allowing the light from the first light-emitting unit 3 and the light from the second light-emitting unit 4 to penetrate through the main component 22 .

The ceiling lamp further includes a circuit substrate 5 for supplying electricity and connecting to an electric power source. The circuit substrate 5 is disposed on the positioning seat 13. The circuit substrate 5 is electrically connected to the second light-emitting unit 4. In the assembly direction 6, the second light-emitting unit 4 is located between the circuit substrate 5 and the third light-transmitting portion 21. Since the wires connected to the mains are electrically connected to the circuit substrate 5, and the circuit substrate 5 is disposed on the positioning seat 13, it is not necessary to move the electrically connected wires during the process of removing the connecting seat 2 from the positioning seat 13. Therefore, even ordinary people who are not familiar with circuits can replace the connecting seat 2 without worrying about the risk of electric shock and can be operated by one person, which is safe, convenient and fast.

More specifically, the positioning base 13 is provided with a second connector 16, which is electrically connected to the circuit substrate 5, and the connecting base 2 is provided with a first connector 24, which is electrically connected to the first light-emitting unit 3. More specifically, one of the first connector 24 and the second connector 16 includes a plurality of conductive coils arranged concentrically at intervals, and the other includes a plurality of conductive members arranged at intervals, and the plurality of conductive members can be detachably pressed against the plurality of conductive coils, so that the main component 22 can remain energized when it rotates to different angles relative to the positioning base 13.
