Description

LED ceiling bulb and ceiling lamp

Technical field

The invention relates to a daily lighting device, in particular to a ceiling lamp device.

Background technique

The lighting industry has experienced incandescent, halogen, fluorescent, and gas discharge lamps. At present, it has entered the era of LED lighting. LED lamps have gained more and more applications in various occasions, and ceiling lamps have gradually tried to use LED light sources. The ceiling LED lamp on the current market is a ceiling lamp that uses the original incandescent lamp (2D, circular fluorescent lamp), and is retrofitted on this basis. The main components are: 1, lamp panel, 2, PCB board (printed circuit board), 3, lampshade, as shown in Figure 1a, Figure 1b.

The lamp panel is fixedly connected to the ceiling through a connection structure, and the lamp panel needs a certain strength to support the weight of the entire ceiling lamp, and is generally made of iron. The PCB board is fixedly connected to the lamp panel, and the lower end surface of the PCB board is mounted with LED lamp beads and driving. Because the light emitted by the luminaire is required to be uniform, the driver must be placed in the center of the PCB, and a certain number of LED beads are evenly distributed around. The lamp cover is detachably connected by the snap structure and the lamp panel.

There are two drive schemes for LED lamp beads. One is the isolation scheme and the other is the non-isolation scheme. The two drive schemes are compared as follows:

a, isolated drive solution:

Advantages: insulation.

Disadvantages: complicated lines, many devices, efficient bottom, large size and high price.

b, non-isolated drive scheme:

Advantages: simple circuit, few devices, high efficiency, small size, and low price.

Disadvantages: not insulated.

Because the lamps need to be turned on when installing the lamps, because there are more LED lamps and more solder joints, each solder joint is an electric conductor, and the lamps cannot be insulated. This non-isolated drive is a dangerous choice and cannot pass the safety. Standard, so only the isolation drive scheme can be selected.

Due to the use of a larger volume of isolated drive, shadows are easily created in the middle. In order to eliminate the middle shadow phenomenon, the central portion of the lampshade is raised to a certain height, and the light of the LED lamp bead driving the side is diffracted to the central portion, and the central shadow is eliminated in this way. Therefore, in general, the LED ceiling lamps in the prior art are fixed by the lamp panel and the ceiling, and then the PCB board with the LED lamp bead and the driver is mounted, and then the lampshade is installed. structure type. The user buys back the entire set of LED ceiling light fixtures. The lamp cover should be unscrewed during installation. Then, fix the lamp plate to the ceiling with screws, connect the power cable, and then screw on the lamp cover. In the future, once the luminaire is broken, the entire luminaire needs to be removed and replaced with new ones. Repeat the above installation process.

In summary, the prior art LED ceiling lamps have the following disadvantages:

a, because the lamp needs to be turned on during installation, there are many LED lamp beads, each with two pads. Cannot be insulated, only the isolated drive can be used, and the non-isolated drive cannot be used.

b, because the driving and LED lamp beads are on the same side of the lamp panel, and the isolation driving volume is large (having a thick thickness), in order to eliminate the central dark area, the lampshade must be raised to eliminate the shadow. Only thicker ceiling lamps can be made, and thin ceiling lamps cannot be made, as shown in Figure 1a and Figure 1b.

c, because the lamp panel and the lampshade can be opened, there is a gap between them, and there will be dust or bugs in the lampshade for long-term use, which affects the appearance and brightness.

d. Once the luminaire is damaged, the lamp panel of the luminaire should be removed as a whole. It is not convenient to replace.

Moreover, the installation and disassembly procedures of these lamps involve dangerous voltages, which need to be operated by a professional electrician, which is very troublesome.

Summary of the invention

The complete LED ceiling light bulb of the present invention has a unique and ingenious structure, and has great breakthrough and unexpected convenience and safety performance effects. The invention combines a lampshade, a PCB board and a lamp panel which have to be separated and disassembled at the same time by using a non-isolated driver to synthesize a non-detachable sealed bulb, and all the above components are selected and optimized by structural components. It's possible to be a lightweight, complete light bulb.
