Abstract
A kind of LED desk lamps with dimmer switch, are related to technical field of lamps, and what is solved is the technical problem for reducing desk lamp with dimmer switch power consumption.The desk lamp with dimmer switch includes circular substrate, and the multiple LED lamp beads on substrate, and for driving the LED drive power of each LED lamp bead, the LED lamp bead has two kinds of warm white lamp bead, cool white light lamp bead, each warm white lamp bead and each cool white light lamp bead are laid around the center alternate intervals of substrate；Each warm white lamp bead is serially connected, and constitutes a warm white light emitting circuit, and the positive pole of warm white light emitting circuit connects the positive pole of LED drive power, the negative pole ground connection of warm white light emitting circuit；Each cool white light lamp bead is serially connected, and constitutes a cool white light illuminating circuit, and cool white light illuminating circuit plus earth, the negative pole of the cool white light illuminating circuit connects the negative pole of LED drive power.The desk lamp with dimmer switch that the utility model is provided, in the case where equal full load works, it is possible to reduce the usage quantity of LED lamp bead.
Description
Technical field
The utility model is related to lamp technology, more particularly to a kind of technology of LED desk lamps with dimmer switch.
Background technology
In current daily light trade, LED lamp is by performances such as its good energy-efficient, small volume, long lifespans
Advantage, is increasingly becoming the main trend of illuminating industry development.Indoors in lighting use, people are not only satisfied with using a kind of
The light fixture of colour temperature.According to different scenes, people need the light fixture with the use of different-colour.Therefore the LED of adjustable color temperature
Tool arises at the historic moment.
Existing LED desk lamps with dimmer switch are both provided with cool white optical circuit parallel with one another（6500K）, warm white optical circuit（2700K）, lead to
Cool white optical circuit is overregulated with the current ratio of warm white optical circuit to realize the overall color temperature regulation of light fixture.This colour temperature regulation side
Formula needs to use more LED lamp bead, and because LED is low-voltage direct light source, the efficiency of LED drive power can be with power supply work(
Rate is reduced and reduced, and this colour temperature regulative mode can cause the output of LED drive power all the way therein to be in low-power all the time
State（Such as it is used to drive the power supply of cool white optical circuit to be in low power state all the time）, therefore power consumption defect high is there is,
So as to reduce the power savings advantages of LED.
Utility model content
For defect present in above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of low
The LED desk lamps with dimmer switch of power consumption.
In order to solve the above-mentioned technical problem, a kind of LED desk lamps with dimmer switch provided by the utility model, including circular substrate,
And the multiple LED lamp beads on substrate, and for driving the LED drive power of each LED lamp bead, it is characterised in that：
The LED lamp bead has two kinds, and a kind of LED lamp bead therein is for sending color temperature value warming up for the light of 2700K
White light lamp bead, another LED lamp bead is the cool white light lamp bead for sending the light that color temperature value is 6500K, each warm white lamp bead
And each cool white light lamp bead is laid around the center alternate intervals of substrate；
Each warm white lamp bead is serially connected, and constitutes a warm white light emitting circuit, and warm white light emitting circuit is just
Pole connects the positive pole of LED drive power, the negative pole ground connection of warm white light emitting circuit；
Each cool white light lamp bead is serially connected, and constitutes a cool white light illuminating circuit, and cool white light illuminating circuit is just
Pole is grounded, and the negative pole of the cool white light illuminating circuit connects the negative pole of LED drive power.
The LED desk lamps with dimmer switch that the utility model is provided, warm white light emitting circuit, cool white light illuminating circuit and LED drive power
Using special connection, traditional parallel connection method is different from, the use of LED lamp beads can be reduced in the case where only warm white is needed
Number, so as to reduce power consumption.
Brief description of the drawings
Fig. 1 is the structural representation of the LED desk lamps with dimmer switch of the utility model embodiment.
Specific embodiment
Below in conjunction with brief description of the drawings embodiment of the present utility model is described in further detail, but the present embodiment and without
It is every to use similar structure of the present utility model and its similar change in limitation the utility model, the utility model all should be listed in
Protection domain, the pause mark in the utility model represents the relation of sum.
As shown in figure 1, a kind of LED desk lamps with dimmer switch that the utility model embodiment is provided, including circular substrate 1, and peace
Dress multiple LED lamp beads on substrate 1, and for driving the LED drive power 2 of each LED lamp bead, it is characterised in that：
The LED lamp bead has two kinds, and a kind of LED lamp bead therein is for sending color temperature value warming up for the light of 2700K
White light lamp bead 31, another LED lamp bead is the cool white light lamp bead 32 for sending the light that color temperature value is 6500K, each warm white
Lamp bead 31 and each cool white light lamp bead 32 are laid around the center alternate intervals of substrate；
Each warm white lamp bead 31 is serially connected, one warm white light emitting circuit of composition, and warm white light emitting circuit
Positive pole connects the positive pole of LED drive power 2, the negative pole ground connection of warm white light emitting circuit；
Each cool white light lamp bead 32 is serially connected, one cool white light illuminating circuit of composition, and cool white light illuminating circuit
Plus earth, the negative pole of the cool white light illuminating circuit connects the negative pole of LED drive power 2.
Total power is not needed to use in the utility model embodiment, when only lighting warm white, so as to reduce power consumption；Need
During changes in temperature light mixed light（Colour temperature reaches 4200K）Warm white light emitting circuit can simultaneously be lighted with cool white light illuminating circuit, so that
The use number of LED lamp beads can be reduced in the case where only warm white is needed, so as to reduce the use of LED power, improve effect
Rate.
