Embodiment Construction

[0023] Such as figure 1 , figure 2 As shown, they are the front schematic diagram and structural diagram of the LED light-emitting module in the desk lamp of the present invention, respectively. In this embodiment, the LEDs are a 2*3 matrix, and the PCB board 22 is connected to the LEDs 23 to control various states of the LEDs 23. , the PCB board 22 and the LED 23 are arranged in the module housing 24, and the light-emitting module mask 21 covers the LED 23 from the front of the LED 23 to protect the LED 23 and the PCB board 22, so that the entire LED light-emitting module forms A whole. Block assembling slots 25 are left on the module housing 24, through which a plurality of LED lighting modules can be assembled on the same plane or on different planes according to actual needs.

[0024] Such as image 3 Shown is the structure schematic diagram of the present invention, the desk lamp of the present invention, comprises base 1, and the light pole 2 of certain shape is hous...

Abstract

The invention relates to a reading lamp that includes lamp-house unit, control unit, constant current drive unit and power supply unit. The lamp-house unit includes one or more LED lighting module. The invention could effectively protect the eyesight of the user. The lighting board is made up of several LED-emitting modules that could be connected with each other by the method of inserting and drawing. And the same series of reading lamp uses the same series of module. Thus, it is convenient to install and maintain.

Description

technical field [0001] The invention relates to a lighting fixture, more specifically, to a desk lamp with a light emitting diode as a light source. Background technique [0002] At present, the table lamps commonly used at home and abroad basically use traditional light sources such as incandescent lamps and fluorescent lamps as illuminants, but incandescent lamps have low electro-optical conversion efficiency, large heat generation, and short service life, only 1000 to 3000 hours. A light emitting diode (Light Emitting Diode, LED) is a semiconductor light-emitting device that can convert electrical energy into light energy. Small quantity (low voltage, low current start), long life (more than 30,000 hours), fast response (can be operated at high frequency), environmental protection (shock resistance, impact resistance is not easy to break, waste can be recycled, no pollution), can Planar packaging has the advantages of being easy to develop into thin, light and short prod...
