A kind of energy-conserving and environment-protective bulb lamp of light source power integrated design
Technical field
The utility model relates to the energy-conserving and environment-protective bulb lamp of a kind of LED lamp, particularly a kind of light source power integrated design.
Background technology
LED is because of its energy-conserving and environment-protective that have, the harmful components such as not mercurous, the advantage such as caloric value is little, the safe and reliable life-span is long, the fields such as outdoor brightening, street illumination, LCD and room lighting have been widely used in, but most LED bulb lamps have adopted light source wiring board and power drives wiring board to divide two-part design, cause LED bulb malfunction rate can not to be in any more, be subject to the impact that power source life brings the service life of LED bulb lamp, and the aluminium base board cost that the light source wiring board adopts is higher, withstand voltage also existing problems.
Simultaneously, the electrochemical capacitor that the current stabilization effect has been arranged in the power supply of traditional LED, and its life-span only had about 10,000 hours, even the life-span of LED light source is very long, thereby also reduced the bulk life time of LED light fixture because of the life-span of power supply, this causes a kind of great wasting of resources, and does not meet the new custom of the current energy-saving and emission-reduction of advocating, environmental protection.
The utility model content
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of energy-conserving and environment-protective bulb lamp of light source power integrated design.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of energy-conserving and environment-protective bulb lamp of light source power integrated design, comprise shell, lampshade, circuit of light sources, power driving circuit, described circuit of light sources comprises the LED lamp, described power driving circuit comprises a rectifier bridge stack, Chip-R, electrochemical capacitor and electric wire, and described circuit of light sources, power driving circuit are integrated on same PCB wiring board.
Further, described PCB wiring board is the single face glass-fiber-plate.
Further, described power driving circuit comprises a CBB electric capacity.
The beneficial effect that the utility model brings has: the integrated design of light source and power drives, make the fault rate of bulb lamp greatly reduce, power supply is suitable with the LED life-span, overcome the bottleneck that the LED bulb lamp brings due to power supply, only use a PCB glass one-sided circuit board, also brought heat insulation, environmental protection, the advantage such as fire-retardant to product.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments,
Accompanying drawing 1 is the left view of the utility model circuit board structure figure;
Accompanying drawing 2 is front views of the utility model circuit board structure figure;
Accompanying drawing 3 is right views of the utility model circuit board structure figure;
Accompanying drawing 4 is the utility model bulb lamp package assembly schematic diagrames.
The specific embodiment
By reference to the accompanying drawings 1, accompanying drawing 2 and accompanying drawing 3, wiring board of the present utility model adopts the single face glass-fiber-plate, and is integrated with simultaneously circuit of light sources and power driving circuit on it.
Circuit of light sources includes some LED lamps 1, they are evenly distributed on PCB wiring board 4, and power driving circuit mainly comprises a rectifier bridge stack 2, Chip-R 3, CBB electric capacity 5, electrochemical capacitor 6 and electric wire 7, so visible power drives here is the mode that has adopted resistance-capacitance depressurization, it utilizes the capacitive reactance current limliting principle of electric capacity, electric main is converted to low-voltage direct driving LED bulb lamp luminous, has advantages of that volume is little, cost is low and simple and practical.
The integrated design of light source and power drives is key technology point of the present utility model.It has overcome, and in the prior art, be subject to the objective reality that power source life affects the service life of LED bulb lamp, reduced the fault rate of LED bulb lamp, makes power supply suitable with the LED life-span.And why adopt PCB glass one-sided circuit board, be because it not only can heat-insulating flame-retardant, also environmental protection more.
Shown in accompanying drawing 4 is the utility model bulb lamp package assembly schematic diagram, and shell 8 lamp bodies are aluminium, and lampshade 9 is the milky white plastic material of PC, and PCB wiring board 4 is positioned at lampshade 9 and is fixed by bolt or other modes.To sum up, the utility model overall structure is simple and clear, and is practical, demonstrated fully the concept of energy-saving and emission-reduction, environmental protection, embodied certain innovative value in the process of China's construction of harmonious society.
At last; although shown with reference to specific embodiment of the utility model and described basic condition of the present utility model; but those skilled in the art is to be understood that; the above is only preferential embodiment of the present utility model, as long as within realizing that with basic identical means the technical scheme of the utility model purpose all should belong to protection domain of the present utility model.
