Abstract
The utility model belongs to the technical field of a lamp provided with a control pole which can change light intensity. The utility model relates to a brightness adjustable electronic desk lamp which comprises a base, a vertical rod movably connected with the base, a lamp shade arranged on the vertical rod, a light reflecting plate arranged in the lamp shade and a light emitting diode LED fixed on the output end of a control circuit in the lamp shade. The brightness adjustable electronic desk lamp uses the light emitting diode LED with a cold light source as a light source, which leads little energy of the desk lamp to be converted into thermal energy which is wasted. The brightness of lamp light can be adjusted, which is obtained without adopting voltage variation. The extinguishing and the luminescence of the partial light emitting diode lead the brightness to be adjusted. Therefore, no energy is lost.
Description
Technical field
The utility model belongs to the technical field of lamp of the control utmost point of the light intensity that changes.
Background technology
The various lamps of now daily or industrial usefulness; the overwhelming majority is active thermolamp; the energy that it consumed has only part to convert light to; and have quite a few power conversion to become heat waste to consume; the adjustment of its brightness; the overwhelming majority realizes so just having quite a few energy to be wasted by changing supply voltage.
Summary of the invention
In order to solve existing desk lamp power conversion is the low and problem that energy loss can not be saved in that the light accent is weak of luminous energy efficient, and the utility model provides the cold light source adjustable brightness electronic lamp that a kind of energy loss is minimum and required brightness cuts down the consumption of energy and also decreases.
This adjustable brightness electronic lamp comprises base, is movably connected in the vertical rod on the base, be contained in the vertical rod lampshade, be contained on the output of the control circuit of reflector in lampshade in the lampshade fixedly LED.
The beneficial effects of the utility model are, light source adopts the LED of cold light source, make this desk lamp almost not have energy conversion to become thermal waste to fall, the capacity usage ratio height, the adjusting of lamplight brightness is not to adopt voltage change to reach, but realize there is not the waste of the energy by extinguishing of part light emitting diode with luminous.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Figure 1 shows that the adjustable brightness electronic lamp office of facing cuts open figure;
Figure 2 shows that along the office of A-A line shown in Figure 1 and cut open figure;
