Abstract
Description
technical field
[0001] The invention relates to a lighting teaching aid made by using waste lamp circuit boards and a manufacturing method thereof. Background technique
[0002] Energy-saving lamps are widely used at present, and energy-saving lamps that cannot be used normally are thrown away as waste. In fact, the main reason for the damage of energy-saving lamps is the damage of the lamp tube. Most of the circuit boards are good and can be reused, and their use time can be infinitely long. Throwing it away directly is a waste of resources, and most of the existing energy-saving lamps are damaged because the bulbs generate high heat and cannot dissipate heat in time, thereby affecting the service life of the energy-saving lamps. Contents of the invention
[0003] The object of the present invention is to provide a lighting teaching aid made of waste lamp circuit boards and its manufacturing method, which has a reasonable structure design, good heat dissipation effect, a...
Examples
Embodiment 1
[0034] See figure 1 and figure 2 , the lighting teaching aid that utilizes waste and old lamp circuit board to make of the present embodiment comprises waste and old energy-saving lamp circuit board 10, LED brightness adjustable circuit and copper-clad board 20; The output end of the board 10 is electrically connected with the input end of the LED brightness adjustable circuit; the LED brightness adjustable circuit is provided with several LEDs arranged on the copper-clad board.
[0035] Several LEDs include LED30 welded on the copper-clad board, several LED30 include three warm-color LEDs (LED1, LED2, LED3) and three cool-color LEDs (LED4, LED5, LED6), and warm-color LEDs and cool-color LEDs are alternately arranged on the copper-clad board 20 on. The copper-clad board 20 is provided with multiple wire slots; the multiple wire slots divide the copper-clad board into multiple areas, so that multiple warm-color LEDs can be serially connected in series, while multiple cool-co...
