Abstract
The utility model relates to a light-emitting diode (LED) bulb; a lamp cap is connected with an upper plastic piece; a lower plastic piece is arranged below the upper plastic piece; a printed circuit board (PCB) is arranged above the lower plastic piece; the LED is connected with the PCB; an outer shell is arranged outside the LED and is fixed above the lower plastic piece; and a metal substrate is arranged between the PCB and the LED. According to the LED bulb, the radiating metal substrate is added between the PCB and the LED, so that heat can be effectively radiated, and the service life of the LED is prolonged; in addition, the LED bulb can adapt to the requirement of wide voltage, has no stroboscopic effect, does not produce any pollution to a power grid, has no interference to electric appliances, and is green, environmental-friendly and energy-saving; and the light-emitting efficiency is high, and the heat output is low.
Description
Technical field
The utility model relates to the lighting apparatus field, relates in particular to a kind of LED lamp.
Background technology
Along with the continuous development of LED technology, LED not only is applied to special lighting fields such as indicator lamp, backlight, and begins to be widely used in various general lightings field as the substitute products of incandescent lamp, electricity-saving lamp.LED has long, advantage such as light efficiency is high, radiationless, shock resistance and low-power consumption of life-span, belong to energy-conservation environmental protection illumination, therefore the LED lamp that with LED is light source also continues to bring out, but existing LED lamp is that the LED light source directly is installed in plastic casing, the LED lantern festival of this mode produces a large amount of heats, and because radiating effect is poor, cause the low and life-span weak point of light efficiency, can't satisfy the needs of normal illumination.
The utility model content
In order to overcome problems such as existing LED lamp radiating effect is poor, service life is short, the utility model provides a kind of LED ball bubble.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of LED ball bubble, and the crown top of burner is connected with last plastic, and plastic is down installed in last plastic below, the PCB circuit board is installed on the following plastic, LED is connected with the PCB circuit board, and the LED outside is provided with shell, and shell is fixed on the following plastic.
Be provided with metal substrate between described PCB circuit board and the LED.
LED ball of the present utility model bubble has increased the heat radiating metal substrate between circuit board and LED, can efficiently radiates heat, prolonged the service life of LED; And can adapt to wide voltage request, no stroboscopic, pollution-free to electrical network, environment protecting and power-saving; The luminous efficiency height, caloric value is little.
Description of drawings
Fig. 1 is the structure chart of the utility model LED ball bubble.
The specific embodiment
LED ball bubble structure of the present utility model as shown in Figure 1, the crown top of burner 1 is connected with last plastic 2, plastic 3 is down installed in last plastic 2 belows, last plastic 2 is made of plastic with following plastic 3, plays the effect of insulation.PCB circuit board 4 is installed on the following plastic 3, LED 7 is connected with PCB circuit board 4, LED 7 is by 4 power supplies of PCB circuit board, LED 7 outsides are provided with shell 5, shell adopts glass to make, shell 5 is fixed in plastic 3 edges down, is provided with metal substrate 6 between PCB circuit board 4 and the LED 7, and metal substrate 6 is used for heat radiation.
Adopt said structure, between PCB circuit board 4 and LED 7, increased heat radiating metal substrate 6, can efficiently radiates heat, prolonged the service life of LED; And LED ball bubble of the present utility model can adapt to wide voltage request, and no stroboscopic is pollution-free to electrical network, environment protecting and power-saving; The luminous efficiency height, caloric value is little.
Claims (2)
1. a LED ball steeps, it is characterized in that: the crown top of burner (1) is connected with last plastic (2), plastic (3) is down installed in last plastic (2) below, following plastic (3) is gone up PCB circuit board (4) is installed, LED(7) be connected with PCB circuit board (4), LED(7) outside is provided with shell (5), and shell (5) is fixed on the following plastic (3).
