BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an LED lighting assembly, and more particularly to an LED lighting assembly for a school bus lamp to reduce a replacement cost.
2. Description of Related Art
The standards of the school bus lamp are regulated strictly by law. With reference to FIG. 8, a school bus lamp has a seat 90, a lighting element 91, a reflector 92 and a lampshade 93. The seat 90 has a plate 94 and a connecting hole 95 formed through the plate 94. The lighting element 91 is mounted on the seat 90. The lighting element 91 has a body 96, a plug 97 and a wing 98. The plug 97 is mounted on the body 96 and inserted into the connecting hole 95 of the seat 90. The wing 98 is mounted around the plug 97. The reflector 92 is mounted on the seat 90 and has a through hole. The reflector 92 is connected to the wing 98 of the lighting element 91, and the lighting element 91 is inserted through the through hole. The lampshade 93 is mounted on the seat 90. The lampshade 93 has an inner surface, an outer surface, a first adjustment portion 931, a second adjustment portion 932 and a third adjustment portion 933. The inner surface faces the lighting element 91 and the reflector 92. The outer surface is opposite to the inner surface. The first adjustment portion 931 and the second adjustment portion 932 are mounted on the inner surface of the lampshade 93, and the second adjustment portion 932 is disposed around the first adjustment portion 931. The third adjustment portion 933 is mounted on the outer surface of the lampshade 93.
An LED (light emitting diode) is a point light source and has small volume and high luminance. Therefore, LED has been widely used in vehicle lamps. If the LED is substituted for the lighting element 91 of the school bus lamp, the seat 90, the reflector 92 and the lampshade 93 of the school bus lamp all need to be changed to comply with the regulations of the school bus lamp. Thus, the LED cannot be used in the school bus lamp directly, and the replacement cost of the school bus lamp is high.
To overcome the shortcomings, the present invention tends to provide an LED lighting assembly to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the invention is to provide an LED lighting assembly to suit a seat and a lampshade of a school bus lamp for reducing the replacement cost.
The LED lighting assembly for a school bus lamp has a reflector and an LED module. The reflector has a base, a reflecting wing, and a connector. The base has a first surface and a second surface opposite to the first surface. The reflecting wing is formed around the base and has a reflecting surface and a rear surface opposite to the reflecting surface. The connector is formed on the second surface of the base. The LED module is mounted on the reflector and has a circuit board, a loading board and at least one LED. The circuit board is mounted on the rear surface of the reflecting wing. The loading board is mounted on the first surface of the base. The at least one LED is mounted on the loading board and is electrically connected to the circuit board.
The LED lighting assembly can be mounted on the seat of the conventional school bus lamp and is covered with the lampshade of the conventional school bus lamp. The connector of the reflector is inserted into a connecting hole of the seat. The light emitted from the LED module illuminates the reflecting surface of the reflecting wing and is reflected to the lampshade by the reflecting surface. Therefore, the LED lighting assembly can be directly mounted on the seat of the conventional school bus lamp for reducing the replacement cost, and a lighting element of the conventional school bus lamp is replaced by the LED lighting assembly. So the LED lighting assembly as described is suitable for the seat and the lampshade of a conventional school bus lamp.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
