一种LED吸顶灯泡及吸顶灯具LED ceiling bulb and ceiling lamp
本发明涉及一种日常照明设备，尤其涉及一种吸顶灯设备。The invention relates to a daily lighting device, in particular to a ceiling lamp device.
照明行业经历了白炽灯、卤素灯、荧光灯、气体放电灯。目前，已进入LED照明时代。LED灯已得到各种场合的越来越多的应用，吸顶灯具也不例外地逐渐尝试采用LED光源。现行市场上的吸顶LED灯灯具是套用了原来的白炽灯(2D、环形荧光灯)的吸顶灯灯具，在这基础上进行改型设计而来。主要组成部件有：1、灯盘，2、PCB板(印制电路板)，3、灯罩，如图1a、图1b所示。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.
灯盘通过连接结构与天花板固定连接，灯盘需有一定的强度支撑整个吸顶灯具的重量，一般用铁皮制作。PCB板与灯盘固定连接，PCB板的下端面安装LED灯珠和驱动的放置。因要求灯具发出的光均匀，须把驱动放置在PCB板中央，周围均匀分布一定数量的LED灯珠。灯罩通过卡扣结构和灯盘可拆卸地连接。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.
对于LED灯珠有两种驱动方案。一种是隔离方案，另一种是非隔离方案。两种驱动方案比较如下：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，隔离驱动方案：a, isolated drive solution:
缺点：线路复杂，器件多，效率底，体积大，价格高。Disadvantages: complicated lines, many devices, efficient bottom, large size and high price.
b，非隔离驱动方案：b, non-isolated drive scheme:
优点：线路简单、器件少、效率高、体积小、价格底。Advantages: simple circuit, few devices, high efficiency, small size, and low price.
缺点：不绝缘。Disadvantages: not insulated.
因安装灯具时需打开灯具，由于LED灯珠较多，焊点更多，每个焊点都是导电体，灯具无法做到绝缘，这样非隔离驱动既是极具危险的选择，也是无法通过安全标准的，所以，只能选用隔离驱动方案。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.
结构形式。用户买回整套LED吸顶灯灯具。安装时需将灯罩拧下，然后，用螺丝把灯盘固定在天花板上，接好电源线，再拧上灯罩。以后，一旦灯具坏了，需把整个灯具卸下，换新的灯具。再重复上述安装过程。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.
综合上述，现有技术的LED吸顶灯存在以下缺点：In summary, the prior art LED ceiling lamps have the following disadvantages:
a，因安装时需打开灯具，LED灯珠又有很多，每个都有两个焊盘。无法绝缘，只能选用隔离驱动，无法使用非隔离驱动。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，因驱动和LED灯珠在灯盘的同一面上，且隔离驱动体积较大(有较厚的厚度)，为了消除中央的暗区就必须加高灯罩来消除阴影。只能做较厚的吸顶灯灯具，无法做薄型的吸顶灯灯具，如图1a、图1b所示。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，因灯盘与灯罩是可以打开的，之间有缝隙，长期使用会出现灯罩内有灰尘或小虫，影响美观和亮度。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，一旦灯具损坏需将灯具的灯盘整体拆除。更换不方便。d. Once the luminaire is damaged, the lamp panel of the luminaire should be removed as a whole. It is not convenient to replace.
并且这些灯具的安装、拆卸程序涉及到危险电压，需要由专业电工人员来操作的，非常麻烦。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.

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. Because the non-isolated driver is relatively small, the non-isolated driver and the LED lamp bead on the PCB can be separated by the upper end and the lower end. The LED lamp bead can be arranged evenly at the lower end of the PCB, so that the light source effect is very ideal. Under the lampshade, the lampshade can be designed to fit the thinness of the PCB board, which can truly become a lightweight and easy to replace integral bulb.
了LED吸顶灯泡中，只是另外设置了与之相匹配的结构简单的供电插座，该供电插座只提供卡扣连接、固定悬挂所述的LED吸顶灯泡，同时为其提供电源连接。而包含LED吸顶灯的大部分部件都整合成一个不可拆卸的灯泡中，这种巧妙的结构改良、大胆的设想，完全突破了传统的LED吸顶灯结构设计形式，从而获得了意想不到的技术效果和显著的技术进步。Due to the unique structural form of the invention, the lamp panel fixed to the roof of the traditional ceiling lamp is skillfully integrated into
In the LED ceiling lamp, only a simple structure power supply socket is provided, and the power socket only provides a snap connection, a fixed suspension of the LED ceiling lamp, and a power connection. Most of the components including LED ceiling lamps are integrated into a non-removable light bulb. This ingenious structural improvement and bold concept completely breaks through the traditional LED ceiling lamp structure design form, thus obtaining unexpected technical effects. And significant technological advances.
从安全性上的提升是很重要的，由于原来传统的LED吸顶灯的结构的局限，当大量的使用者在灯具损坏后都会凭借传统灯具修理的经验去拆卸检修，但是由于LED灯具的独特性以及大都采用隔离驱动的现状，灯具内部往往会带有具有人体伤害性的强电，这个即便是厂家一而再地加以安全提示，但是其可拆式结构往往会导致每年都会有很多不够专业的人员在检修、安装中收到不同程度的伤害。然而本发明的独特构思却是从根本上解决了这种安全隐患，我们提供的是一个把可能具有强电隐患的所有部件都巧妙整合成一个完整的LED吸顶灯泡，以及一个结构及其简单的供电插座的形式，一旦灯具有损坏，则只需将包含灯罩、PCB板和灯盘在内的LED吸顶灯泡整体废弃，重新购买一个LED吸顶灯泡与供电插座插接即可，这个过程及其简单而非常安全，即便是毫无专业知识的家庭主妇也可以顺利地完成灯泡的安装和更换，不像传统灯具需要专业电工安装、检修还安全隐患重重，所以本发明的巧妙结构所带来的意想不到的便捷性、安全性的极大提升是不可忽视的，而其间所带来的社会效益也是巨大的。The improvement from safety is very important. Due to the limitations of the traditional LED ceiling lamps, when a large number of users are damaged, they will be dismantled and repaired by the experience of traditional lamp repair, but due to the uniqueness of LED lamps. And most of them use the status quo of isolation drive. The inside of the lamp often has strong electric power with human body damage. Even if the manufacturer repeatedly gives safety tips, its detachable structure often leads to many unprofessional ones every year. Personnel receive different degrees of damage during maintenance and installation. However, the unique concept of the present invention fundamentally solves this security risk. We provide a complete LED ceiling light bulb with all the components that may have strong electrical hazards, and a simple structure. In the form of a power socket, once the lamp is damaged, it is only necessary to discard the LED ceiling bulb including the lampshade, the PCB board and the lamp panel, and re-purchase an LED ceiling bulb to be plugged into the power socket. It is simple and very safe. Even a housewife without professional knowledge can successfully complete the installation and replacement of the light bulb. Unlike traditional lamps, which require professional electricians to install and repair, it is also a safety hazard. Unexpected convenience and safety have not been neglected, and the social benefits brought about by it are enormous.
同时由于本发明的LED灯珠排布更趋合理，灯罩不需要考虑消除中央暗区等问题，其结构、形状形式也就可以设计成各种形状、各式各样，大大满足了日趋多样化的消费者的需求。At the same time, since the LED lamp bead arrangement of the invention is more reasonable, the lamp cover does not need to consider the problem of eliminating the central dark area, and the structure and shape form can be designed into various shapes and various types, which greatly meets the diversification. The needs of consumers.
所述的灯盘和灯罩之间密闭固定连接，从而形成一个密闭空间，这样紧密连接成一体的LED吸顶灯泡内部就完全杜绝了出现灰尘和钻入大量小虫的可能，而这些也正是大大影响灯具使用效果和使用寿命的长期难以解决的老大难问题。The lamp tray and the lamp cover are tightly and fixedly connected to form a closed space, so that the inside of the LED ceiling light bulb which is tightly connected and integrated can completely eliminate the possibility of dust and drilling a large number of bugs, and these are exactly A long-term problem that greatly affects the use effect and service life of the luminaire.
