Description

Technical Field

[0001] The utility model relates to a light bulb, more particularly to an LED light bulb. Background Art

[0002] LED bulbs are gradually replacing incandescent bulbs due to their long lifespan and low hazards. LED bulbs are commonly divided into household LED bulbs and special LED bulbs according to their particularity. One of the special places is the ship environment. Due to the characteristics of the ship environment such as high and low temperatures, vibration, and humidity, the bulbs need to be further optimized.

[0003] The specific problems are: Home LED bulbs often place the driver board in the shell cavity, and the exposed electronic component solder pins of the driver board are insulated by applying silicone or wrapping with insulating materials. The process is complicated and wastes resources. In addition, due to the vibration environment on the ship, the insulation can easily fall off and cause short circuit hazards. The driver board of home LED bulbs is mostly fixed to the LED light source board in the form of solder, and the driver board is mostly placed in the shell cavity without any fixed form. When used in the vibration environment on the ship, the driver board can easily fall off, causing the entire lamp to not light up, increasing maintenance costs and wasting manpower and material resources. It is not practical and safe, so these are not suitable for use in vibration environments such as ships. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an LED bulb that can withstand vibrations without falling off, has high insulation performance, is easy and simple to operate, has high timeliness, and can effectively improve product performance.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an LED light bulb, comprising a shell body, a light source board and a driving plate, wherein the driving plate is installed at the lower end of the light source board, the shell body is provided with an inner cavity for installing the driving plate, the inner cavity is provided with a card slot and an abutment surface, the driving plate is provided with a limiting surface and a guide portion, the guide portion is used to slide along the card slot, and the limiting surface is used to abut against the abutment surface.

[0006] The present invention is further configured as follows: the shell body includes a mounting surface, the mounting surface is located at the cavity opening of the inner cavity, and a limiting member is provided between the light source board and the mounting surface.

[0007] The utility model is further configured as follows: the limiting member includes screws or glue.

[0008] The utility model is further configured as follows: the shell body includes a shell radiator and a shell base, and the lower end of the shell base is connected to a lamp holder.

[0009] The utility model is further configured as follows: a thread groove is provided on the lamp holder seat, a threaded portion is provided on the outside of the shell base, and the lamp holder seat is screwed to the threaded portion.

[0010] The utility model is further configured as follows: the shell radiator is made of heat dissipation plastic material.

[0012] The present invention is further configured as follows: the clamping slot is arranged at the bottom of the inner cavity, and the guide portion is arranged at the bottom end of the driving plate.

[0013] The utility model is further configured to include a lampshade, which is detachably mounted on the upper end of the shell.

[0014] In summary, the utility model has the following beneficial effects: 1. During the installation of the driving plate and the light source board, the driving plate can move downward stably through the sliding cooperation of the guide part and the card slot until the abutting surface abuts the limit surface, thereby playing the role of positioning and fixing the driving plate.

[0015] 2. The lamp holder is screwed to the threaded part. After the thread is tightened and fixed, it is riveted to the shell by a riveting machine to achieve double fixation, so that the whole lamp will not fall off in a vibrating environment. It has high insulation performance, is firm and reliable, and is easy to install, which can greatly save manpower and material resources.

[0016] 3. The shell body is composed of a shell radiator (heat dissipating plastic and other materials) and a shell base (insulating plastic and other materials). The insulating material of the shell base wraps the cavity, which has the effect of low density and light weight. Even in a confined space, it can quickly conduct the heat generated by the LED away, ensuring that the bulb works stably for a long time without affecting performance or shortening life due to heat accumulation.
